Effect of ambient temperature on human skeletal muscle metabolism during fatiguing submaximal exercise. (1/372)

To examine the effect of ambient temperature on metabolism during fatiguing submaximal exercise, eight men cycled to exhaustion at a workload requiring 70% peak pulmonary oxygen uptake on three separate occasions, at least 1 wk apart. These trials were conducted in ambient temperatures of 3 degrees C (CT), 20 degrees C (NT), and 40 degrees C (HT). Although no differences in muscle or rectal temperature were observed before exercise, both muscle and rectal temperature were higher (P < 0.05) at fatigue in HT compared with CT and NT. Exercise time was longer in CT compared with NT, which, in turn, was longer compared with HT (85 +/- 8 vs. 60 +/- 11 vs. 30 +/- 3 min, respectively; P < 0.05). Plasma epinephrine concentration was not different at rest or at the point of fatigue when the three trials were compared, but concentrations of this hormone were higher (P < 0.05) when HT was compared with NT, which in turn was higher (P < 0.05) compared with CT after 20 min of exercise. Muscle glycogen concentration was not different at rest when the three trials were compared but was higher at fatigue in HT compared with NT and CT, which were not different (299 +/- 33 vs. 153 +/- 27 and 116 +/- 28 mmol/kg dry wt, respectively; P < 0.01). Intramuscular lactate concentration was not different at rest when the three trials were compared but was higher (P < 0.05) at fatigue in HT compared with CT. No differences in the concentration of the total intramuscular adenine nucleotide pool (ATP + ADP + AMP), phosphocreatine, or creatine were observed before or after exercise when the trials were compared. Although intramuscular IMP concentrations were not statistically different before or after exercise when the three trials were compared, there was an exercise-induced increase (P < 0.01) in IMP. These results demonstrate that fatigue during prolonged exercise in hot conditions is not related to carbohydrate availability. Furthermore, the increased endurance in CT compared with NT is probably due to a reduced glycogenolytic rate.  (+info)

African runners exhibit greater fatigue resistance, lower lactate accumulation, and higher oxidative enzyme activity. (2/372)

Nine African and eight Caucasian 10-km runners resident at sea level volunteered. Maximal O2 consumption and peak treadmill velocity (PTV) were measured by using a progressive test, and fatigue resistance [time to fatigue (TTF)] was measured by using a newly developed high-intensity running test: 5 min at 72, 80, and 88% of individual PTV followed by 92% PTV to exhaustion. Skeletal muscle enzyme activities were determined in 12 runners and 12 sedentary control subjects. In a comparison of African and Caucasian runners, mean 10-km race time, maximal O2 consumption, and PTV were similar. In African runners, TTF was 21% longer (P < 0.01), plasma lactate accumulation after 5 min at 88% PTV was 38% lower (P < 0.05), and citrate synthase activity was 50% higher (27.9 +/- 7.5 vs. 18.6 +/- 2.1 micromol. g wet wt-1. min-1, P = 0.02). Africans accumulated lactate at a slower rate with increasing exercise intensity (P < 0.05). Among the entire group of runners, a higher citrate synthase activity was associated with a longer TTF (r = 0.70, P < 0.05), a lower plasma lactate accumulation (r = -0.73, P = 0.01), and a lower respiratory exchange ratio (r = -0.63, P < 0.05). We conclude that the African and Caucasian runners in the present study differed with respect to oxidative enzyme activity, rate of lactate accumulation, and their ability to sustain high-intensity endurance exercise.  (+info)

Evidence of O2 supply-dependent VO2 max in the exercise-trained human quadriceps. (3/372)

Maximal O2 delivery and O2 uptake (VO2) per 100 g of active muscle mass are far greater during knee extensor (KE) than during cycle exercise: 73 and 60 ml. min-1. 100 g-1 (2.4 kg of muscle) (R. S. Richardson, D. R. Knight, D. C. Poole, S. S. Kurdak, M. C. Hogan, B. Grassi, and P. D. Wagner. Am. J. Physiol. 268 (Heart Circ. Physiol. 37): H1453-H1461, 1995) and 28 and 25 ml. min-1. 100 g-1 (7.5 kg of muscle) (D. R. Knight, W. Schaffartzik, H. J. Guy, R. Predilleto, M. C. Hogan, and P. D. Wagner. J. Appl. Physiol. 75: 2586-2593, 1993), respectively. Although this is evidence of muscle O2 supply dependence in itself, it raises the following question: With such high O2 delivery in KE, are the quadriceps still O2 supply dependent at maximal exercise? To answer this question, seven trained subjects performed maximum KE exercise in hypoxia [0.12 inspired O2 fraction (FIO2)], normoxia (0.21 FIO2), and hyperoxia (1.0 FIO2) in a balanced order. The protocol (after warm-up) was a square wave to a previously determined maximum work rate followed by incremental stages to ensure that a true maximum was achieved under each condition. Direct measures of arterial and venous blood O2 concentration in combination with a thermodilution blood flow technique allowed the determination of O2 delivery and muscle VO2. Maximal O2 delivery increased with inspired O2: 1.3 +/- 0.1, 1.6 +/- 0.2, and 1.9 +/- 0.2 l/min at 0.12, 0.21, and 1.0 FIO2, respectively (P < 0.05). Maximal work rate was affected by variations in inspired O2 (-25 and +14% at 0.12 and 1.0 FIO2, respectively, compared with normoxia, P < 0.05) as was maximal VO2 (VO2 max): 1.04 +/- 0.13, 1. 24 +/- 0.16, and 1.45 +/- 0.19 l/min at 0.12, 0.21, and 1.0 FIO2, respectively (P < 0.05). Calculated mean capillary PO2 also varied with FIO2 (28.3 +/- 1.0, 34.8 +/- 2.0, and 40.7 +/- 1.9 Torr at 0.12, 0.21, and 1.0 FIO2, respectively, P < 0.05) and was proportionally related to changes in VO2 max, supporting our previous finding that a decrease in O2 supply will proportionately decrease muscle VO2 max. As even in the isolated quadriceps (where normoxic O2 delivery is the highest recorded in humans) an increase in O2 supply by hyperoxia allows the achievement of a greater VO2 max, we conclude that, in normoxic conditions of isolated KE exercise, KE VO2 max in trained subjects is not limited by mitochondrial metabolic rate but, rather, by O2 supply.  (+info)

Exercise VE and physical performance at altitude are not affected by menstrual cycle phase. (4/372)

We hypothesized that progesterone-mediated ventilatory stimulation during the midluteal phase of the menstrual cycle would increase exercise minute ventilation (VE; l/min) at sea level (SL) and with acute altitude (AA) exposure but would only increase arterial O2 saturation (SaO2, %) with AA exposure. We further hypothesized that an increased exercise SaO2 with AA exposure would enhance O2 transport and improve both peak O2 uptake (VO2 peak; ml x kg-1 x min-1) and submaximal exercise time to exhaustion (Exh; min) in the midluteal phase. Eight female lowlanders [33 +/- 3 (mean +/- SD) yr, 58 +/- 6 kg] completed a VO2 peak and Exh test at 70% of their altitude-specific VO2 peak at SL and with AA exposure to 4,300 m in a hypobaric chamber (446 mmHg) in their early follicular and midluteal phases. Progesterone levels increased (P < 0.05) approximately 20-fold from the early follicular to midluteal phase at SL and AA. Peak VE (101 +/- 17) and submaximal VE (55 +/- 9) were not affected by cycle phase or altitude. Submaximal SaO2 did not differ between cycle phases at SL, but it was 3% higher during the midluteal phase with AA exposure. Neither VO2 peak nor Exh time was affected by cycle phase at SL or AA. We conclude that, despite significantly increased progesterone levels in the midluteal phase, exercise VE is not increased at SL or AA. Moreover, neither maximal nor submaximal exercise performance is affected by menstrual cycle phase at SL or AA.  (+info)

Explosive-strength training improves 5-km running time by improving running economy and muscle power. (5/372)

To investigate the effects of simultaneous explosive-strength and endurance training on physical performance characteristics, 10 experimental (E) and 8 control (C) endurance athletes trained for 9 wk. The total training volume was kept the same in both groups, but 32% of training in E and 3% in C was replaced by explosive-type strength training. A 5-km time trial (5K), running economy (RE), maximal 20-m speed (V20 m), and 5-jump (5J) tests were measured on a track. Maximal anaerobic (MART) and aerobic treadmill running tests were used to determine maximal velocity in the MART (VMART) and maximal oxygen uptake (VO2 max). The 5K time, RE, and VMART improved (P < 0.05) in E, but no changes were observed in C. V20 m and 5J increased in E (P < 0.01) and decreased in C (P < 0.05). VO2 max increased in C (P < 0.05), but no changes were observed in E. In the pooled data, the changes in the 5K velocity during 9 wk of training correlated (P < 0.05) with the changes in RE [O2 uptake (r = -0.54)] and VMART (r = 0.55). In conclusion, the present simultaneous explosive-strength and endurance training improved the 5K time in well-trained endurance athletes without changes in their VO2 max. This improvement was due to improved neuromuscular characteristics that were transferred into improved VMART and running economy.  (+info)

Role of the oxygen uptake efficiency slope in evaluating exercise tolerance. (6/372)

OBJECTIVE: To investigate the interprotocol agreement of oxygen uptake efficiency slope (OUES). METHODS: 16 Japanese children and adolescents (10 boys and six girls) underwent two sessions of maximal exercise testing according to the following two treadmill protocols: the standard Bruce protocol and the rapidly increasing staged (RIS) protocol. Maximal oxygen uptake (VO2max), the ventilatory anaerobic threshold (VAT), and the OUES were obtained from the gas analysis data. Agreement between the protocols was tested by means of the Bland-Altman method. RESULTS: Interprotocol agreement was excellent for the OUES (limit of agreement, -18% to 17% of the mean value), slightly less good for VO2max (limit of agreement, -20% to 24% of the mean value), and poor for the VAT (limit of agreement, -31% to 31% of the mean value). CONCLUSION: These results confirm the clinical usefulness of the OUES as a measure of evaluating exercise tolerance in the paediatric population.  (+info)

Analysis of the aerobic-anaerobic transition in elite cyclists during incremental exercise with the use of electromyography. (7/372)

OBJECTIVES: To investigate the validity and reliability of surface electromyography (EMG) as a new non-invasive determinant of the metabolic response to incremental exercise in elite cyclists. The relation between EMG activity and other more conventional methods for analysing the aerobic-anaerobic transition such as blood lactate measurements (lactate threshold (LT) and onset of blood lactate accumulation (OBLA)) and ventilatory parameters (ventilatory thresholds 1 and 2 (VT1 and VT2)) was studied. METHODS: Twenty eight elite road cyclists (age 24 (4) years; VO2MAX 69.9 (6.4) ml/kg/min; values mean (SD)) were selected as subjects. Each of them performed a ramp protocol (starting at 0 W, with increases of 5 W every 12 seconds) on a cycle ergometer (validity study). In addition, 15 of them performed the same test twice (reliability study). During the tests, data on gas exchange and blood lactate levels were collected to determine VT1, VT2, LT, and OBLA. The root mean squares of EMG signals (rms-EMG) were recorded from both the vastus lateralis and the rectus femoris at each intensity using surface electrodes. RESULTS: A two threshold response was detected in the rms-EMG recordings from both muscles in 90% of subjects, with two breakpoints, EMGT1 and EMGT2, at around 60-70% and 80-90% of VO2MAX respectively. The results of the reliability study showed no significant differences (p > 0.05) between mean values of EMGT1 and EMGT2 obtained in both tests. Furthermore, no significant differences (p > 0.05) existed between mean values of EMGT1, in the vastus lateralis and rectus femoris, and VT1 and LT (62.8 (14.5) and 69.0 (6.2) and 64.6 (6.4) and 68.7 (8.2)% of VO2MAX respectively), or between mean values of EMGT2, in the vastus lateralis and rectus femoris, and VT2 and OBLA (86.9 (9.0) and 88.0 (6.2) and 84.6 (6.5) and 87.7 (6.4)% of VO2MAX respectively). CONCLUSION: rms-EMG may be a useful complementary non-invasive method for analysing the aerobic-anaerobic transition (ventilatory and lactate thresholds) in elite cyclists.  (+info)

Exercise-induced changes in plasma atrial natriuretic peptide and brain natriuretic peptide concentrations in healthy subjects with chronic sleep deprivation. (8/372)

Recent observations have shown that plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) correlate with cardiac function or prognosis in heart failure patients. However, relatively little is known about changes in their plasma concentration during commonly occurring physiological states such as fatigue. Therefore, this study was designed to examine the physiological changes of plasma ANP and BNP concentrations using a chronic sleep-deprivation model. Bicycle ergometer cardiopulmonary exercise tests were performed in 10 healthy volunteers (mean age: 22.7 years). Blood samples for measuring ANP and BNP were drawn during the resting state and immediately after each exercise test. Cardiac output (CO) was measured during the exercise test by the impedance method. The study conditions were designed as follows: (A) a day following a period of normal sleep (control state) and (B) a day preceded by 1 month during which sleep lasted <60% of normal (chronic sleep-deprived state). Results were as follows. (1) Peak oxygen uptake and peak CO decreased during the sleep-deprived state compared with the control state. (2) There was no difference between peak heart rates measured during exercise under the 2 conditions. (3) Plasma ANP concentration during exercise increased significantly during the control state, whereas only a tendency toward increase was observed during the sleep-deprived state. (4) Plasma BNP concentration during exercise tended to increase in the control state compared with the resting state, whereas there was no difference in plasma BNP between after exercise and resting state in the sleep-deprived state. These results indicate that changes of ANP or BNP induced by exercise tended to be decreased by chronic sleep deprivation.  (+info)

Several studies have demonstrated the presence of a second rise in ventilation during incremental exercise, RCP, which is clearly distinguishable from the ventilatory threshold11,15-18 and must, hence, be based on different physiological mechanisms.6,13,19 There are indications from other studies that RCP occurs in response to an initial decrease in blood pH which represents the beginning of failure of the bodys buffering capacity. However, experimental proof was lacking. The present investigation indicates that blood pH is a relevant stimulus for the hyperventilation starting at RCP. However, other mechanisms must also be partly responsible for the hyperventilation.. To our knowledge, this investigation represents the first attempt to elucidate the physiological basis of RCP by directly, that is, intravenously, manipulating blood pH in human beings. Due to the invasiveness of the procedures, only a small number of subjects were recruited. However, their response to the bicarbonate intervention ...
Purpose. The aim of the study was to assess lactate and glucose concentrations as indicators of anaerobic capacity in a highlyranked female junior swimmer. Methods. Ten trials of a 5 × 200 m backstroke step test were performed between December 2008 and July 2011. Each trial was video-recorded and blood samples were drawn from the ear lobe 1 min after completion of each step to measure lactate and glucose concentrations. Results. During maximal effort, lactate concentrations of 5.1 to 13.1 mmol · l-1 were recorded, while glucose concentration varied from 6.6 to 8.1 mmol · l-1. Correlations between lactate and glucose concentrations were significant in most tests. The shape of lactate and glucose curves revealed an improvement in the swimmers endurance ability during subsequent tests. Conclusions. Analysis of fluctuations in lactate and glucose concentrations appears to be a relevant indicator of the anaerobic capacity of experienced swimmers ...
A rate responsive pacemaker measures a metabolic demand parameter of a patient. The metabolic demand parameter is converted to a corresponding metabolic indicated rate which determines the pulse rate of the pacer. The converting is based on a profile dependent on the predicted anaerobic threshold level of the patient, as well as his or her age and physical fitness.
Your anaerobic threshold is the level at which your body oeprates while exercising in which the lactic acid that builds up in your muscles is being created at a higher rate than that at which its being neutralized and reabsorbed. This threshold is characterized by pain and discomfort, but its also seen to be the ideal place to work out in terms of improving your overall short-duration fitness and strength.. Incorporating some training at or around your anaerobic threshold can help you to dramatically improve you short term strength, speed and agility. Athletes that participate in sports or events that are not characterized by sustained or long distance training will typically work out frequently at or around this level so as to best improve their fitness. However, because the anaerobic threshold is close to your bodys limit of how far you can push it while exercising, its important that you be aware of how to safely incorporate it into your workout.. Monitor the Threshold Closely. First, you ...
Results. Statistically significant changes between two measurement points were determined in variables: the speed of swimming at aerobic threshold (Vaet1, Vaet2; t=-3.13; P=0.035), the speed of swimming at anaerobic threshold (Vant1, Vant2; t=-8.57; P=0.001) and Red blood cells (RBC1, RBC2; t=-3.34; P=0.029). The speed of swimming at aerobic threshold (Vaet) increased by 4.1%, and 3.3% anaerobic threshold (Vant) after returning from altitude training. In the hematologic blood results, it can be seen that the number of red blood cells increased by 3.7% after returning from altitude training, while the level of haemoglobin and the percentage of haematocrite remained the same ...

The protocol started at a rate of 80 cycles per minute (cycle.min-1) for 2 min with subsequent increments of 10 cycle.min-1 every minute until exhaustion, with measurements of heart rate, oxygen uptake and ventilation throughout test. After, the two methods were used to determine the values of these variables corresponding to the AT for each of the exercises. Comparisons were made using two-way ANOVA for repeated measures with Bonferronis post hoc test. To correlate the same variables determined by the two methods, the intra-class correlation coefficient test (ICC) was used ...
Koldioxid är en central parameter för metabolismen i alla levande varelser. Hos människan regleras koldioxidhalten främst genom andningen. Därför är det viktigt att kunna mäta och övervaka koldioxidhalten i fysiologiska applikationer så väl inom sportmedicin som inom vården, till exempel på intensivvårdsavdelningar. Dessa mätningar kräver adekvat mätutrustning.. Syftet med denna avhandling är att kritiskt granska föreslagna metoder för övervakning av andningsaktiviteten, att föreslå och utveckla förbättringar, samt att föreslå och utveckla nya applikationer för mätning av koldioxidhalten i utandningsluften med hjälp av en elektroakustisk sensor.. Mätning av koldioxid i utandningsluften har den fördelen över andra föreslagna metoder för andningsövervakning att den även ger information om förhållandet i arteriellt blod då partialtrycket för koldioxid i slutet av ett andetag är lika stort som i artärblod hos lungfriska personer.. Den föreslagna tekniken ...

Yes, a HRM would be a great tool for you. The effect of the Beta-blocker is to keep your BP at safe levels by keeping your HR from going beyond your anaerobic threshold (AT). Right beyond this point of AT, however, your working muscles will start accumulating lots of lactic acid if you continue to make them work hard. Although the beta blocker keeps your cardiac-vascular system from straining, you can really tear up your legs by making work in while oxygen debt. ...

Results The maximal oxygen uptake of the participants was 53 ml/kg/min (95% CI 45 to 60). In an unassisted callout, a typical rucksack load was 17% of body mass. Ascent time was 56 min (95% CI 40 to 72), of which 82% (95% CI 66% to 98%) was completed at hard or very hard intensity (above the respiratory compensation point). Descent time with a stretcher was 58 min (95% CI 52 to 64), of which only 6% (95% CI −4% to 16%) was completed at hard or very hard intensity. Correlations between heart rate and oxygen uptake were similar (p=0.254 by analysis of variance) during laboratory (r=0.72) and field testing, especially for the ascent (r=0.75). ...
Methods and Results-This study was a double-blind, placebo-controlled, crossover trial conducted in children and young adults after Fontan. Subjects were randomized to receive placebo or sildenafil (20 mg three times daily) for 6 weeks. After a 6-week washout, subjects crossed over for an additional 6 weeks. Each subject underwent an exercise stress test at the start and finish of each phase. After taking sildenafil, subjects had a significantly decreased respiratory rate and decreased minute ventilation at peak exercise. At the anaerobic threshold, subjects had significantly decreased ventilatory equivalents of carbon dioxide. There was no change in oxygen consumption during peak exercise, although there was a suggestion of improved oxygen consumption at the anaerobic threshold. Improvement at the anaerobic threshold was limited to the subgroup with single left or mixed ventricular morphology and to the subgroup with baseline serum brain natriuretic peptide levels ≥100 pg/mL.. ...
On the second exercise test, those with MS and those who were healthy were able to repeat the same results on the exercise as on day one. However, those with CFS/ME were unable to achieve this and reached their anaerobic threshold faster and at a lower workload compared to day one," Dr. Hodges says.. "This suggests that even though they were as fit as the healthy controls, post-exertional malaise [the feeling of fatigue] after exercise, shows up by them not being able to achieve the same workload at anaerobic threshold or at their peak.". Dr. Hodges says there are still several factors that need to be examined. "Our study also showed that some individuals with CFS/ME took up to four weeks to recover following the two exercise tests, which was not apparent in the healthy individuals who were back to normal the following day.". To gain better understanding, Dr. Hodges is completing another trial examining the physiological differences in repeated maximal exercise at 48 hours and 72 hours. "We will ...
Changes in the participants VO2 max and peak power output increased significantly due to training effects, not specifically the mask, but there was not a difference in magnitude between groups.1 There were also no significant changes in the pulmonary function and hematological variables during the training period. So, things like hemoglobin levels, hematocrit levels, and forced expiratory volume in one minute, did not improve due to the mask. The respiratory compensation threshold (+10.2) and power output at respiratory compensation threshold (+16.4).1 Respiratory compensation is when plasma pH can be altered by a changing respiratory rate. 2 ...
Information provided by a lactate threshold test has a number of purposes. By understanding the role that lactate plays in exercise metabolism, the exercise physiologist can use the information from lactate threshold tests to predict proper racing and training paces, and assess the fitness of a subject or the efficacy of the training program.
Compared to the 8-minute duration, the use of 4- or 6-minute exercise intervals during an incremental-intensity test produces results that overestimate maximal lactate steady state exercise intensity for endurance trained runners. Implication. When testing athletes who have performed considerable endurance work, and an incremental test is used to assess anaerobic threshold, maximum lactate steady state, etc., the duration of each increment needs to be quite long because short-period intervals will lead to erroneous inferences. For trained runners, 8 minutes appears to be the minimum period to be spent at each step of an incremental testing procedure.. Return to Table of Contents for this issue. ...
The goal of radiation therapy is to give as much dose as possible to the exact target location and minimizing any dose to a normal tissue. Advances of Cyber-physical control systems allow planning and provide very accurate treatments. However, the current technology does not sufficiently compensate a respiratory movement that is especially important in case of lung (area) cancer. In this paper we present a model of radiation treatment system developed to analyze a system that compensates respiratory motion. We use Uppaal, an integrated tool environment for modeling, validation and verification of real-time systems modeled as networks of timed automata, extended with data types (bounded integers, arrays, etc.).. ...

... (MTB) is divided into cross-country and downhill disciplines. Within each discipline there are an array of competitive events. Most athletes specialise in one discipline due to the diverse physiological demands.. Cross-country races involve riders completing laps of a 5-9km circuit, including hill climbs and technical descents either solo or in teams of 2-10. An ability to maintain a high aerobic capacity over a prolonged duration is essential. Races include short course (maximum 6km circuit laps); Circuit (minimum 6km course; 1-2hrs & 12-24hrs); Enduro (1 or more days of different events); Point to Point (different start & finish; 25-100km). Downhill races typically involve riders competing at maximal intensity for a race of 2-4 minutes. A high degree of strength is required for the high power outputs required to be successful as well an advanced anaerobic capacity. Races include downhill (solo; 1.5-3.5km; technical; 2-5 min); 4-cross (4 riders pass a series of gates; 30-40 ...
Vulnerability to harvest, such as capture by trawl, is likely a complex, integrative characteristic influenced by several morphological and behavioural traits [13,25]. The ecological and evolutionary importance of intraspecific variation in phenotypes (e.g. animal personality) has been the focus of a large body of recent literature, and several studies have begun to highlight the importance of behavioural traits within the context of harvest vulnerability [13,17,18]. This study shows for the first time that physiological traits also play a key role in determining which individuals are captured during trawling and which are not. Fish displayed repeatable, intraspecific variation in vulnerability, directly influenced by anaerobic capacity and swimming ability, with additional links to aerobic swimming performance and SMR. The fact that some fish are consistently more prone to capture suggests that suites of traits that influence overall vulnerability to trawling could be selected by ...
Australia is a very large country but the main centre for CPET is in Melbourne where the pioneering work of Dr Older and Dr Hall on preoperative analysis of operative risk was performed. The work still continues but the laboratory at the Western Hospital is now headed up by Dr Simon Frenkel. He is a Respiratory Physician but has a major interest in preoperative CPET. He is strongly supported by Dr Robert Smith, an anaesthetist, who was also involved in the original work. Dr Older still visits the laboratory and is also involved with the Swinburne University of Technology where he is an Adjunct Professor. Dr Hall has moved to Brisbane and we hope to hear from him from time to time.. We get enquiries from many centres on just how we perform our tests on surgical patients. Firstly we do not push the elderly patients to their peak VO2 as we are more interested in the anaerobic threshold. The average age of our patients is 64 and despite thousands of patients being tested we have not had anyone ...

For most people, instead of the numbers swimming through the mind the whole time they are exercising, I would use a RPE test. RPE is the rate of perceived exertion. On a scale from 1-10, how are you feeling? Are you working your absolute hardest (10) or are you just now waking up (1)? An exerciser can not stay at a 10 for very long, so please don’t try! The upper RPEs are reserved to increase our stamina, not for calorie burning. In fact, this is the anaerobic threshold, where the body is no longer burning but conserving calories. In a solid cardio workout, where the heart rate stays evenly elevated for 20-90 minutes, the RPE should be around a 6 throughout. In an interval workout, alternate between a 3-4 and a 7-8 for the workout. This type of workout will increase stamina, strengthen the heart, challenge the muscles involved, and burn more calories. However, the constant cardio workout is important as well. In an average regimen, make sure both of these types of cardio activity are used.
The primary outcome measure for our trial will be the time taken to attain the anaerobic threshold, which is a performance marker of fatigability that is unaffected by patient motivation or perception ...

Lactate Threshold is the maximum steady state effort that can be maintained without lactate continually increasing. Train above the Lactate Threshold and you will bonk, overtrain, or not gain the benefits of training in the first place. Train suboptimally and your performance will not improve. Your body naturally produces lactate as you train from which it can conveniently create more glycogen to fuel your muscles. However, this isnt an instant process. If you use up too much glycogen before your body can reproduce it from lactic acid you will unfortunately, bonk. Hence, its essential to know your own personal lactate threshold for training and racing to perform optimally and avoid overtraining and the dreaded bonk. Take the guesswork out of training zones!. ...
Abstract The aim of this study was to compare the lactate (La) removal during active recovery at three different work rates below the individual anaerobic threshold (IAT). Recently, it has been recommended that exercise intensity should be determined in relation to the IAT instead of the percentage of maximal oxygen uptake (VO2max), especially for training and research purposes. Therefore, we defined the recovery work rates by calculating 50% of the threshold difference (DT) between the IAT and the individual ventilatory threshold (IVT) work rates, then choosing the IVT+50%DT, the IVT and the IVT50%DT. All these work rates fell within the range (30-70% VVO2max) previously reported for optimal La removal. After a 6-min treadmill run at 90% VV_ O2max, soccer players [n=12 male, age 22 (1) years] performed, in a random order, four 30-min recovery treatments: (1) run at IVT+50%DT, (2) at IVT, (3) at IVT50%DT, (4) passive recovery. La was obtained at 1, 3, 6, 9, 12, 15, 20, 25 and 30 min of recovery. ...
But as my knowledge of the subject is not in the same *country*, not to mention ballpark, I will quote from his book:. "It is now clear that the blood lactate concentrations do not show a clearly defined, abrupt threshold response during exercise of progressively increasing intensity. Rather, blood lactate concentrations begin to rise as soon as progressive exercise commences. However, at low exercise intensities, the rate of the increase is so slow that it is barely noticeable. Only when the exercise becomes more intense does the rise become apparent, which perhaps explains the erroneous impression that blood lactate concentrations increase abruptly when the lactate threshold is reached" (Lore of Running, Noakes, p.159). This is only scratching the surface of what he has to say on the subject, which I think is fascinating - even if (like you mentioned) its not particularly relevant to my training as a recreational racer. I *do* worry less about hitting some magical training intensity now, ...
Large Scale Evaluation of CPET as Predictor of Survival Outcome is Needed Researchers from the U.K. determined that preoperative cardiopulmonary exercise testing (CPET) is a specific predictor of 90-day survival following liver transplantation. Study results available in the February issue of Liver Transplantation, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases, shows that the CPET measurement-the anaerobic threshold or fitness level-significantly predicts mortality in patients post-transplantation. CPET is a non-invasive measure of cardiorespiratory fitness and has been previously used as a predictor of morbidity and mortality following other types of major surgeries. "Liver transplantation carries a significant mortality risk in the early days following surgery," explains Dr. James Prentis from Freeman Hospital in Newcastle upon Tyne in the U.K. "An accurate preoperative assessment like CPET could help minimize patient mortality and ...
Youre probably well versed in high-intensity interval training (HIIT), a form of training that utilises interval training of near maximal intensity followed by periods of low-intensity recovery. Possible benefits of HIIT are improved anaerobic capacity, anabolic hormone up-regulation, heart-rate recovery, and an increased max heart rate, all during a shorter workout period (fewer than 30 minutes).. A-Career -In -Fitness -Polaroid -14It has become very popular over the last few years as numerous products and services are promoting high-intensity training such as Insanity, boot camps and CrossFit. It has created an ever-increasing demand on the fitness industry to promote high-intensity training where the consumer feels like they are working to maximum effort and exhaustion. Unfortunately, this high-intensity training (HIT) has lost an I for interval in translation.. An interval can be defined as a pause or interlude, as between periods of intense activity. In many of the high-intensity ...
The purpose of this study was to determine the effects of the pre-workout supplement Assault™ (MusclePharm, Denver, CO, USA) on upper and lower body muscular endurance, aerobic and anaerobic capacity, and choice reaction time in recreationally-trained males. Subjective feelings of energy, fatigue, alertness, and focus were measured to examine associations between psychological factors and human performance. Twelve recreationally-trained males participated in a 3-week investigation (mean +/- SD, age: 28 +/- 5 y, height: 178 +/- 9 cm, weight: 79.2 +/- 15.7 kg, VO2max: 45.7 +/- 7.6 ml/kg/min). Subjects reported to the human performance laboratory on three separate occasions. All participants completed a baseline/familiarization day of testing that included a maximal graded exercise test for the determination of aerobic capacity (VO2max), one-rep maximum (1-RM) for bench and leg press to determine 75% of 1-RM, choice reaction tests, and intermittent critical velocity familiarization.

Why did Kurz say in the summer 1996 newsletter that aerobic burns mostly fat and very little glucose? I thought that if you did aerobic exercises at the aerobic zone (which would be at least 70% of your maximum heart while not reaching the anaerobic threshold), then your body would burn close to the same percent of carbs as fats. Also, I thought that at the beginning of increased exertion during aerobic exercise that the body undergoes glycolysis producing pyruvate which then reacts with oxygen (Krebs cycle) to produce carbon dioxide and water and releasing energy ...

A method and system for easily and automatically determining the extent of test coverage for a design-under-test (DUT). Incremental test coverage information is gathered from the application of test cases to the DUT, and cumulative test coverage information is maintained. The incremental test coverage and cumulative test coverage information are fed into a correlation process, which correlates valid bus transactions automatically generated from a configuration file describing the DUT with the incremental and cumulative test coverage information. The correlation process determines which valid bus transactions have or have not been applied in testing the DUT.

The aim of the present paper is to show how an approach based on human health risk analysis can be used as a decisional tool for the evaluation of impacts on population and for deciding between different waste treatment processes. The situation in which the increasing production of solid wastes cannot be confined in the old existing Municipal Solid Waste landfill (settled in Genoa, Liguria Region, Italy) is used as a case study. Risk assessment for human health due to air, surface water, groundwater and soil contamination is performed in different scenarios for the old landfill and compared with alternative Waste-to-Energy management solutions that consider thermal treatment by gasification of the total waste or gasification of the dry fraction coupled with anaerobic digestion of the wet fraction, plus biogas combustion with or without sludge and bottom ash/slag disposal in the old landfill ...
with 10 second rest periods] may be one of the best possible training protocols Dr. Tabata told Dick Winett in a personal communication: The rate of increase in VO2max [14% in only 6 weeks] is one of the highest ever reported in exercise science.

Several of the earliest articles on this website were about high intensity intervals for fitness and fat loss; articles 10 and 11 in our Aerobic Exercise category discuss Dr. Tabata s research. Because of my interest in high-intensity aerobics (I first wrote about it in Ripped 3), quite a number of people emailed about the recent research on sprint interval training done by Kirsten Burgomaster and colleagues at McMaster University, Hamilton, Ontario, Canada, and published in the Journal of Applied Physiology (June 2005).

The lactate threshold is like a watershed between the aerobic and anaerobic exercises. When below this threshold, the body is mainly based on aerobic metabolism while above this threshold, the body is changed to be based on anaerobic metabolism. It is a critical indicator for maintaining long-time high-strength aerobic exercise. By collecting enormous amount of running pace data via the running meter, it is possible to estimate your lactate threshold. Recommended Pace T and Heart Rate T can directly apply to your Strength T running training. ...
Pacing is critical. Suppose you are running those 800 meter bouts and you start out by sprinting the first 200 meters and then have a gradual slow-down for the next 600 meters. Your average pace might be on target, but you have failed to reach VO2 max since you started with this huge anaerobic effort and then settled into a pace slower than your VO2 max intensity.. There is something called a slow-component to VO2 max. This means that for any pace above lactate threshold, you will eventually reach VO2 max if the exercise is continued. So you do want to go fast, but to spend the most amount of time near VO2 max, you want a pace you can sustain for 2-3 minutes. If performed correctly your oxygen consumption will approach VO2 max about half-way through each hard effort. So if your workout is 6 x 2.5 minutes, you might in reality only spend a total of 7.5 minutes at VO2 max, which is fine. If performed poorly you may only spend a few seconds of each interval at VO2 max or none at all.. ...

Coachs Corner- By Alison Dunlap. What can I do this winter to get ready for my upcoming mountain bike season? Racing well during the summer requires a commitment to training in the off-season that you may not have done in years previous. The hard work you put in right now will pay huge dividends in May, June, and July. Even if you dont have any plans to race, training through the winter can keep you from losing the fitness you worked so hard to gain last summer as well as create a solid aerobic foundation upon which everything else in cycling is built upon. There are three major areas you need to focus on in your off-season; endurance, maximum sustainable power, and anaerobic power (Dave Morris, Performance Cycling; Training for Power, Endurance, and Speed, 2003 p. 55). A carefully constructed training plan will allow you to be ready to race in April and then peak for the big events in late June and July.. The first component of your off-season training plan should be endurance. Endurance ...

The purpose of this study was to compare the ventilatory threshold (VT) between treadmill walking against a horizontal impeding force (horizontal load walking) and a cycle ergometer exercise. Seven adult men volunteered to participate in this study. They performed horizontal load walking (velocity: 1.11 m/s) and a cycle ergometer exercise (pedaling frequency: 60 rpm), with loads imposed using a ramp slope technique. Oxygen uptake at the VT during horizontal load walking was greater than that during a cycle ergometer exercise (p
To the Editor:. In a recent issue of Circulation, Tolle et al reported on exercise-induced pulmonary arterial hypertension (PAH) as a well-circumscribed syndrome with clinical cardiopulmonary exercise testing and hemodynamic criteria.1 The authors are to be commended for this article, which is original and clinically relevant. However, we were intrigued by the presentation of their results as log-log plots of mean pulmonary arterial pressure (PAP) as a function of predicted oxygen consumption (V̇o2).. According to the authors, the logPAP-logV̇o2 relationship normally shows an inflection point with increased slope above the anaerobic threshold ("takeoff pattern"), in contrast to a "plateau pattern" identified in exercise-induced PAH and in established PAH. Because V̇o2 and cardiac output are tightly correlated, accounting for "highly concordant" PAP versus cardiac output (Q) and PAP versus V̇o2 log-log plots, the authors explain these patterns by exercise-induced pulmonary vasoconstriction in ...

The effect of different pedalling rates (40, 60, 80, 100 and 120 rev min-1) on power generating capability, oxygen uptake (O2) and blood lactate concentration [La]b during incremental tests was studied in seven subjects. No significant differences in O2,max were found (mean +/- S.D., 5.31 +/- 0.13 l min-1). The final external power output delivered to the ergometer during incremental tests (PI,max) was not significantly different when cycling at 60, 80 or 100 rev min-1 (366 +/- 5 W). A significant decrease in PI,max of 60 W was observed at 40 and 120 rev min-1 compared with 60 and 100 rev min-1, respectively (P , 0.01). At 120 rev min-1 there was also a pronounced upward shift of the O2-power output (O2-P) relationship. At 50 W O2 between 80 and 100 rev min-1 amounted to +0.43 l min-1 but to +0.87 l min-1 between 100 and 120 rev min-1.

Coachs Corner- By Alison Dunlap. What can I do this winter to get ready for my upcoming mountain bike season? Racing well during the summer requires a commitment to training in the off-season that you may not have done in years previous. The hard work you put in right now will pay huge dividends in May, June, and July. Even if you dont have any plans to race, training through the winter can keep you from losing the fitness you worked so hard to gain last summer as well as create a solid aerobic foundation upon which everything else in cycling is built upon. There are three major areas you need to focus on in your off-season; endurance, maximum sustainable power, and anaerobic power (Dave Morris, Performance Cycling; Training for Power, Endurance, and Speed, 2003 p. 55). A carefully constructed training plan will allow you to be ready to race in April and then peak for the big events in late June and July.. The first component of your off-season training plan should be endurance. Endurance ...

Objectives: To determine physical activity levels in pediatric patients who underwent the Fontan procedure, and their relationship to functional status and exercise capacity. Study Design: We studied 147 patients (ages 7 to 18 years) at a median of 8.1 years after Fontan, as part of the Pediatric Heart Network cross-sectional study of Fontan survivors. Assessment included medical history, self-reported physical activity, parent-completed Child Health Questionnaire (CHQ), cardiopulmonary exercise testing and measured physical activity level by accelerometry (MTI Actigraph). Results: Measured time spent in moderate and vigorous activity was markedly below normal at all ages, particularly in females, and was not significantly related to self-reported activity levels, or to maximum VO2, VO2 at anaerobic threshold or maximum work rate on exercise testing. Lower measured activity levels were significantly related to lower perceived general health, but not to self-esteem, physical functioning, social ...

F. Policarpo, I. Majdalane, S. Luna Cruz, & P. Roquetti Fernandes University Pedro de Valdívia, Chillan, Chile The need to establish trusted parameters of physical fitness, being the exercise a physical activity or focused on high performance, and the reliability of the results found in physical test as well as the development of new methods, have been the focus of several areas of research. PURPOSE: The objective of this study is to validate the applicability of equations to estimate consumption VO2máx developed on a treadmill to estimate consumption VO2máx using a cycle ergometer. METHODS: The study had a sample of 19 volunteers, men, (22 ± 3,5 years old, 70,3 ± 5,8 Kg, 176 ± 6 cm, 10,4 ± 4,5% of Body Fat), physically active and healthy, who have done maximal incremental test on a treadmill (add the maximal value of VO2máx for the test on treadmill) and incremental test on a cycle ergometer a week later, to establish the VO2máx 53,30±5,68 ml.kg-1.min-1 for a load of 269,74±28,36W,
Rationale: Salbutamol, was of 2010 relieved from WADAs prohibited list needing a strict diagnosis of asthma, and can now be used more freely among athletes. Some studies have showed enhancing effects of oral salbutamol on anaerobic power in recreational men and women. However, no studies have investigated this in elite athletes. The aim of this study was to examine whether oral salbutamol, taken acutely and over a period of two weeks, increases anaerobic power during repeated Wingate tests in elite cyclists.. Method: We enrolled 20 non-asthmatic elite cyclists (M), aged 25.8±4.4yrs, VO2max 68.6±5.8 ml/min/kg, and a training volume of 14.4±3.6 h/wk. The cyclists were randomized into either oral salbutamol 8 mg (SAL) or placebo (PLA) in a double-blinded parallel study. The protocol consisted of three 30-s Wingate tests separated by two minutes of recovery. The intervention consisted of study visits at baseline, after acute ingestion and after two week ingestion taken two-three hours prior to ...
An advantage of going slightly slower is that it leaves me with more energy to concentrate on other things, one of which is my posture on the bike. I have not been through a proper bike fitting process and I am not convinced the bike is set-up quite right for me. I have yet to find a decent way to do this without paying far more than I want at a bike shop. One problem that I have been having is lower back pain after a couple of hours riding. On this long ride though I paid more attention to my posture and realised I was slumping down in the saddle. My hips are rotating backwards while I slouch forward, this seems to happen more when I am putting in harder effort, up hills for example. So I am trying to make a concious effort to keep my back straight and maintain a better posture. It seemed to help on this ride as I felt much better at the end of the ride than I have for the last couple ...

Background Patients with systemic sclerosis (SSc) may develop exercise intolerance due to musculoskeletal involvement, restrictive lung disease, left ventricular dysfunction, or pulmonary vasculopathy (PV). The latter is particularly important since it may lead to lethal pulmonary arterial hypertension (PAH). We hypothesized that abnormalities during cardiopulmonary exercise testing (CPET) in patients with SSc can identify PV leading to overt PAH. Methods Thirty SSc patients from the Harbor-UCLA Rheumatology clinic, not clinically suspected of having significant pulmonary vascular disease, were referred for this prospective study. Resting pulmonary function and exercise gas exchange were assessed, including peakVO2, anaerobic threshold (AT), heart rate- VO2 relationship (O2-pulse), exercise breathing reserve and parameters of ventilation-perfusion mismatching, as evidenced by elevated ventilatory equivalent for CO2 (VE/VCO2) and reduced end-tidal pCO2 (PETCO2) at the AT. Results Gas exchange patterns
The relationship between exercise capacity, as assessed by peak oxygen consumption, and outcome is well established in heart failure (HF), but the predictive value of cardiopulmonary exercise testing (CPET) has been recently questioned, for two main reasons. First, the decisional power of CPET in the selection of heart transplantation candidates has diminished, since newer therapeutic options and the shortage of donor hearts have restricted this curative option to extremely advanced HF patients, frequently not able to perform a symptom-limited CPET. Secondly, the use of CPET has become more complex and sophisticated, with many promising new prognostic indexes proposed each year. Thus, a modern interpretation of CPET calls for selective expertise that is not routinely available in all HF centres. This position paper examines the history of CPET in risk stratification in HF. Throughout five phases of achievements, the journey from a single CPET parameter (i.e. peak oxygen consumption) to a ...
OBJECTIVE: To assess energy depletion in skeletal muscle in patients with congestive heart failure by measuring blood purine metabolites during exercise and, at the same time, determine the implications of the ammonia response to exercise in these patients. SETTING: Tottori University Hospital, Yonago, Japan. PATIENTS: 49 heart failure patients (New York Heart Association (NYHA) grades I-III) and 16 normal subjects. MAIN OUTCOME MEASURES: Blood lactate, ammonia, and hypoxanthine levels were measured during exercise with expired gas analysis. RESULTS: In normal exercising subjects as well as in each heart failure subgroup, the ammonia threshold was significantly higher than both the lactate threshold [control: 21.8 (SD 5.3) v 17.4 (3.3) ml/kg/min; NYHA class I: 18.9 (3.8) v 15.5 (2.6); class II: 14.8 (2.5) v 12.7 (2.4); class III: 13.5 (2.6) v 11.8 (2.5)] and the ventilatory threshold (P , 0.01). The difference between the ammonia and lactate thresholds was noted in all normal subjects and in all ...
For this study, we employed a single-blind, randomized, counterbalanced, crossover experimental design. Subjects visited the SSHES Physiology Laboratory on three different occasions. During the first visit, a preliminary incremental exercise test (2 min at 50 W + 50 W increments every 2 min) was performed until exhaustion [operationally defined as a pedal frequency of less than 60 revolutions/min (RPM) for more than 5 s despite strong verbal encouragement] on an electromagnetically braked cycle ergometer (Excalibur Sport, Lode, Groningen, The Netherlands) to measure V̇o2peak, and peak power output, which was calculated according to the equation of Kuipers et al. (35). The cycle ergometer was set in hyperbolic mode, which allows the power output to be set independently of pedal frequency over the range of 30-120 RPM. Before the incremental exercise test the position on the cycle ergometer was adjusted for each subject, and settings were recorded so that they could be reproduced at each ...

Supervised exercise (SE) in patients with type 2 diabetes improves oxygen uptake kinetics at the onset of exercise. Maintenance of these improvements, however, has not been examined when supervision is removed. We explored if potential improvements in oxygen uptake kinetics following a 12-week SE that combined aerobic and resistance training were maintained after a subsequent 12-week unsupervised exercise (UE). The involvement of cardiac output (CO) in these improvements was also tested. Nineteen volunteers with type 2 diabetes were recruited. Oxygen uptake kinetics and CO (inert gas rebreathing) responses to constant-load cycling at 50% ventilatory threshold (VT), 80% VT, and mid-point between VT and peak workload (50% Δ) were examined at baseline (on 2 occasions) and following each 12-week training period. Participants decided to exercise at a local gymnasium during the UE. Thirteen subjects completed all the interventions. The time constant of phase 2 of oxygen uptake was significantly ...
Results A lower aerobic capacity was significantly related to sick leave (HR=0.98; t=-0.018; 95% CI: 0.970 to 0.994). There was a significant positive relationship between aerobic capacity and work ability (a=0.165; 95% CI: 0.122 to 0.208). Also, lower work ability was significantly related to sick leave after controlling for aerobic capacity (HR=0.97; b=-0.033, 95% CI: 0.949 to 0.987). Work ability mediated 27.8% (95% CI: 10.4 to 45.2) of the total effect of aerobic capacity on sick leave. There was no influence of age on the relationship between aerobic capacity and sick leave.. ...
The electrical polarization of sodium iron phosphate glasses, containing from 5.3 to 14.9 mol% Na2O and with a constant Fe/P ratio of 0.67, was investigated by thermally stimulated polarization current (TSPC), and by depolarization current (TSDC) techniques. The partial TSDC measurements showed a group of distributed partial peaks, P1, whose maximum ranged from 186 to 227 K. A group of higher temperature peaks, P2, was found in a narrower temperature range from 257 to 264 K, with an additional process, P2′, at about 240 K. The process P1 was caused by a dipolar relaxation showing a compensation with the compensation point at Tc=247 K. The physical meaning of the compensation point could not be related to analogous phenomena in organic polymers. The higher temperature peaks represent space charge relaxations greatly affected by the increase in Na2O content and influenced by the remaining polarization and conductivity. The most likely cause for the electrical relaxation was an interaction between the Na

  • These sports are purely aerobic but, at times, the cyclist switches to a type of anaerobic work: knowing how far you can push certainly helps to better manage your oxygen and, consequently, athletic preparation and performance. (technogym.com)
  • The aim of this study was to make an approach on the importance of the anaerobic threshold (AT) and the peak oxygen uptake in soccer players, and compare the results found in players to those existing in the specialized literature. (scielo.br)
  • For the heat rate monitor, you need to use a specified protocol (fixed time intervals and speeds) and the Conconi test is one of the earliest (albeit controversial) test to measure Lactate Threshold. (speedendurance.com)
  • Threshold test: why measure the anaerobic threshold? (technogym.com)
  • The third method, the Conconi test, is the simplest and most used way to determine an athlete's anaerobic threshold. (technogym.com)
  • First off, congratulations on doing an Anaerobic Threshold Heart Rate (AT HR), test, or for having your Coach make you do it! (thepracticaltriathlete.com)
  • Purpose: To validate the Muscle Power Sprint Test (MPST) against the Wingate Anaerobic cycling Test (WAnT) in a group of youth with cerebral palsy (CP). (lww.com)
  • The Muscle Power Sprint Test was found to be a valid test for measuring anaerobic capacity in children and adolescens with cerebral palsy who are able to walk or run independently. (lww.com)
  • The more you perform high-intensity workouts, the better you can condition your anaerobic threshold and process lactate in the body - and the faster you'll be able to swim, bike, or run. (polar.com)
  • Interval training uses different work and rest periods allowing the body to temporarily exceed the lactate threshold at a high intensity, and then recover (reduce blood-lactate). (wikipedia.org)
  • Anaerobic threshold varies from athlete to athlete. (polar.com)
  • Most athletes enter the anaerobic threshold zone when they're putting in some serious work and a lot of power output over a short period of time - like during an interval or sprint. (polar.com)
  • What's the best way to measure anaerobic threshold? (polar.com)
  • 6. The pacemaker of claim 1 wherein said anaerobic threshold is related to a maximum nominal rate of said patient. (google.com)
  • The blood lactate concentration at the anaerobic threshold is called the "maximum steady-state lactate concentration" (MLSS). (wikipedia.org)
  • If you've ever done a track workout - say 400-meter repeats - you've probably gotten into the anaerobic zone on each repeat. (polar.com)
  • Spruit MA, Gosselink R, Decramer M. High Heart Rates at Anaerobic Threshold in Healthy Women. (jamanetwork.com)
  • To maintain total aerobic metabolism, there must be little inhomogeneity in the muscle blood flow/O 2 consumption ratio (Qm/V̇O 2 m) since a ratio of 5.5 or less would obligate anaerobic metabolism (Figure 1). (springer.com)
  • system analysis of human sports activity and anaerobic threshold definition in the system activity categories. (smjournal.ru)
  • Note that this individual has a very low anaerobic threshold (ATI), shown here at the elbow of the curve at about 60% of their MHR. (thefreedictionary.com)
  • Here's everything athletes should understand about anaerobic threshold. (polar.com)
  • On the other hand, our other study showed that the anaerobic threshold of CP subjects with lower physical activities decreased. (thefreedictionary.com)
  • For athletes who regularly do interval-style workouts , their anaerobic thresholds will be much higher and more conditioned than those who only do long, steady-state workouts - or don't train at all. (polar.com)
  • 16. The pacemaker of claim 15 wherein said additional mapping means is activated when said anaerobic threshold is outside said preselected range. (google.com)
