Anaerobic Threshold
The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements.
Exercise Test
Controlled physical activity which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used.
Oxygen Consumption
The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)
Exercise Tolerance
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.

Pulmonary Gas Exchange
The exchange of OXYGEN and CARBON DIOXIDE between alveolar air and pulmonary capillary blood that occurs across the BLOOD-AIR BARRIER.
Exercise
Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.
Heart Rate

Sensory Thresholds
The minimum amount of stimulus energy necessary to elicit a sensory response.
Physical Endurance
The time span between the beginning of physical activity by an individual and the termination because of exhaustion.
Running
An activity in which the body is propelled by moving the legs rapidly. Running is performed at a moderate to rapid pace and should be differentiated from JOGGING, which is performed at a much slower pace.
Physical Fitness
The ability to carry out daily tasks and perform physical activities in a highly functional state, often as a result of physical conditioning.
Respiration
The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).
Heart Failure
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Carbon Dioxide
A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals.

Analysis of Variance
A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.
Auditory Threshold
The audibility limit of discriminating sound intensity and pitch.
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

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)

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 Practical Guide to the Interpretation of Cardiopulmonary Exercise Tests is a short, but comprehensive, guide for those who are involved in the supervision of exercise tests and interpretation of cardiopulmonary exercise test (CPET) data. It is a clear and concise guide which will also be of interest to those who request CPETs and who wish to understand more about how to use the results. The first four chapters cover the reasons why a CPET may be requested, pre-test assessment, supervision of the test to ensure that it is safe, and the practicalities of the test itself. Subsequent chapters look in detail at the key CPET measurements of heart rate, ventilation, oxygen uptake, and carbon dioxide output. There are chapters on the parameters that can be derived from these basic measurements: ventilatory equivalents, oxygen pulse, and the respiratory exchange ratio. Further chapters show how the anaerobic threshold and respiratory compensation point are obtained, and how they can be used to ...

In this study, the ability of microRNA-1906 (miR-1906) to attenuate bone loss in osteoporosis was evaluated by measuring the effects of a miR-1906 mimic and inhibitor on the cellular toxicity and cell viability of MC3T3‐E1 cells. Bone marrow-derived macrophage (BMM) cells were isolated from female mice, and tartrate-resistant acid phosphatase signalling was performed in miR-1906 mimic-treated, receptor-activated nuclear factor kappa-B (NF-κB) ligand (RANKL)-induced osteoclasts. In-vivo, osteoporosis was induced by ovariectomy (OVX). Rats were treated with 500 nmol/kg of the miR-1906 mimic via intrathecal administration for 10 consecutive days following surgery. The effect of the miR-1906 mimic on bone mineral density (BMD) in OVX rats was observed in the whole body, lumbar vertebrae and femur. Levels of biochemical parameters and cytokines in the serum of miR-1906 mimic-treated OVX rats were analysed. The mRNA expression of toll-like receptor 4 (TLR4), myeloid differentiation primary response ...

Lactate Test #2: What happened to aerobic capacity?Lactate Test #2: What happened to aerobic capacity?
On May 21st, I did my second lactate capacity test of the season. I planned on both an aerobic and anaerobic capacity check during the test. But the aerobic part of the test was too long. It likely caused a bit of glycogen depletion.. Depletion would have compromised the results of the anaerobic part of the test. To minimize interference between the two tests, I did the anaerobic part two days later. I may do that from now on.. The combined test had mixed results. By both heart rate and pace, my aerobic capacity appears to have weakened. (This is shown by the blue line being above and left of the red line) My anaerobic capacity appears to be the same as in early April (14.5 versus 14.6).. ...

Lactate Threshold Training | The Benefits & How To Do | MYPROTEIN™Lactate Threshold Training | The Benefits & How To Do | MYPROTEIN™
During cardiovascular exercise there are different levels of intensity you can choose to work at depending on your goal and ability. Each threshold intensity is identified by a percentage of your maximum heart rate (MHR); for instance, the aerobic zone is between 70%-80% of your MHR and focusses on developing the cardiovascular system. This article will address the lactate training threshold, which is a high-intensity state of cardiovascular exercise that still relies on oxygen for performance.. Depending on a individuals level of cardiovascular fitness, the lactate zone varies. For athletes this zone is usually between 75%-85% of MHR; those who have a higher level of fitness will tend to fall closer to the 85% mark than the 75% mark, and vice versa. As for untrained athletes, this zone can be around the 50%-60% mark. The lactate threshold edges very closely toward the anaerobic threshold, which is the zone of heart rate in which the body is performing at too high an intensity to gather enough ...

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. ...

The present study investigated the effects of pubertal status on peak oxygen uptake (VO2peak), respiratory compensation point (RCP), and ventilatory threshold (VT) in young soccer players using different body size descriptors. Seventy-nine soccer players (14 prepubescent, 38 pubescent and 27 postpubescent) participated in this study. A maximal exercise test was performed to determine the VO2peak, RCP, and VT. Ultrasonography was used to measure lower limb muscle volume (LLMV). LLMV (mL-b) was rated as the most effective body size descriptor to normalize VO2peak (mLO2•mL-0.43•min-1), RCP (mLO2•mL-0.48•min-1), and VT (mLO2•mL-0.40•min-1). The values of VO2peak, RCP, and VT relative to allometric exponents derived by LLMV were similar among groups (p , .05; 0.025 , η2 , 0.059) when the effect of chronological age was controlled. Allometric VO2peak, RCP, and VT values were: 100.1 ± 7.9, 107.5 ± 9.6, and 108.0 ± 10.3 mLO2.mL-0.43•min-1; 51.8 ± 5.3, 54.8 ± 4.7, and 57.3 ± 5.8 ...

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.. ...

Differentiating Chronic Fatigue Syndrome - National Pain ReportDifferentiating Chronic Fatigue Syndrome - National Pain Report
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 ...

Faster #7 - Heart Rate Monitors | Erics Arcana and RiderX
Lots of the cool guys have heart rate monitors. Should you get one?. Im going to assume that you are doing a set of structured workouts. So, if youre doing that, you need to set your training zones. You can do that by taking a percentage that you determine use 220-age or one of the other formulas, and then train based on that. But there are a few problems with that. First of all, none of the formulas to determine max hr are of much use, as there are wide variances of maximum heart rate across the population. But even if that formula does work for you, its a poor way to set ranges. Basically, one of your goals is to push your anaerobic threshold to a higher percentage of your maximum heart rate. To do this, you may need to work out near your anaerobic threshold. The problem is that that threshold is a moving target. A range set based on a maximum will likely be too high when you are untrained, and too low when you are well trained. The right way to set ranges is to use a field test, like the ...

lactate threshold Archives - Best Exercise Bike Review
As you can see, your lactate threshold essentially defines the upper limit of your sustainable efforts in training or even in competition.. Once you reach the point where you rely more heavily on your glycolytic system for energy, then youre exercising on borrowed time. You should try and save precious gylcogen and carbs for the sprint finish or defining moments of a race. The winner of a race usually isnt the strongest but is the one with the most energy left at the end. The longer time you can keep with the pace under or at your threshold the better chance you have of winning in the end. Therefore increasing your LT is like the holy grail of cycling.. When blood lactate accumulates, it will hinder your muscles ability to contract and forcing you to slow down or even stop. So naturally, the more work you can do before you reach your lactate threshold, the better. That will translate into better results.. Think of it this way, if the pace you can hold at your lactate threshold is higher than ...

Individual Differences
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. ...

Modeling and analysis of radiation therapy system with respiratory compensation using Uppaal - Murdoch Research RepositoryModeling and analysis of radiation therapy system with respiratory compensation using Uppaal - Murdoch Research Repository
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.).. ...

Mountain BikingMountain Biking
Mountain biking (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 ...

Anaerobic Metabolism and Catchability | Proceedings of the Royal Society of London B: Biological SciencesAnaerobic Metabolism and Catchability | Proceedings of the Royal Society of London B: Biological Sciences
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 ...

Metabolism & VO2Max - Savannah Sport and Wellness
VO2 stands for Volume of Oxygen. There is a direct link between your oxygen usage and your fitness level. The more oxygen your body can use, the more fit you are. Likewise, the higher the phyiscal demands you place on your body, the more oxygen is required to provide energy to meet those demands.. The amount of Oxygen you use can also indicate how many calories you burn at each intensity level.. A VO2 test measures your heart rate and oxygen consumption during a treadmill or bike test that increases in intensity until you are at your max effort. The results of the test include your VO2 and heart rate throughout the test and at your max effort. They will inform training zones heart rate and/or pace for optimal training and peak performance.. Training zones are determined by establishing 4 key threshold markers: resting, aerobic threshold, anaerobic threshold and max.. Aerobic Threshold is the intensity level at which your body can no longer provide all the oxygen required. Your body switches from ...

Calculating Maximum or Maximal Heart Rate | How Effective Is Your Exercise and Workout?
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.

7 tips to accelerating your vertical speed7 tips to accelerating your vertical speed
If its a trail race or a mountain run with big vertical ascents that youre training for, then its also critical to focus on your lactate threshold. Do this through longer duration interval workouts done at a slightly lower intensity than the V02 training outlined above. The goal is to work consistently until you cant work at that intensity anymore. After rest and recovery, your body will become stronger. Intervals should be between 10 to 30 minutes in length, with half the recovery time, and a total training time of around 45 to 60 minutes. For example ...

Father of Hunter Biden Says No One Wants Their Kids to Grow Up to Be Like President TrumpFather of Hunter Biden Says No One Wants Their Kids to Grow Up to Be Like President Trump
Posted on 12/18/2019 12:25:18 AM PST by conservative98. Democratic presidential candidate Joe Biden on Monday said nobody wants their children to grow up like President Donald Trump. As his son Hunter Biden faces allegations of drug abuse, soliciting prostitutes, and participating in an influence peddling scheme at a Ukrainian gas company, the former vice president assailed Trumps character while speaking at a New York City fundraiser. The American people, including the senators who are going to vote to acquit him, know no one wants their kid to grow up like him, Biden said. David Rutz breaks down the most important news about the enemies of freedom, here and around the world, in this comprehensive morning newsletter. No psychiatrist or anyone in the association can talk about the fact that this president has a serious problem, Biden said. Narcissism is a mental deficiency. And it means you cannot tolerate any criticism at all . Whether hes a narcissist or not, some people think hes a ...
