Danladi I. Musa, Samuel A. Adenirn, A. U. Dikko and Stephen P. Sayers. ​. Purpose: Examine the impact of an 8-week program of high-intensity interval training on high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC) and the atherogenic index (TC/HDL-C) in 36 untrained men ages 21 - 36.. ​. Conclusions: Findings support the recommendations of high-intensity interval training as an alternative mode of exercise to improve blood lipid profiles for individuals with acceptable physical fitness levels.. ​. IN PLAIN ENGLISH: Having high levels of HDL cholesterol can play a protective role against coronary atherosclerosis since it acts as a lipid scavenger. In past studies, continuous activity endurance training has been proven to elevate HDL-C. To also elevate HDL-C levels and protect against coronary issues, high-intensity interval training can also be used. ...
The popularity of high-intensity interval training (HIIT), which consists primarily of repeated bursts of high-intensity exercise, continues to soar because its effectiveness and efficiency have been proven in use by both elite athletes and general fitness enthusiasts. Surprisingly, few resources have attempted to explain both the science behind the HIIT movement and its sport-specific application to athlete training. Thats why Science and Application of High-Intensity Interval Training is a must-have resource for sport coaches, strength and conditioning professionals, personal trainers, and exercise physiologists, as well as for researchers and sport scientists who study high-intensity interval training.
Background Exercise may improve cardiorespiratory fitness in people with schizophrenia, however, possible condition-specific cardiorespiratory disadvantages, a scarcity of methodologically sound studies, and conflicting results raise questions about the effect of exercise on maximal oxygen uptake (VO2max) in this group. The primary aim of this study, therefore, was to investigate the effect of high-intensity interval training on VO2max in people with schizophrenia. Second, we sought to determine whether the intervention would have an effect on general physical activity (PA) level and body composition. Methods Eighty-two patients with schizophrenia were randomly assigned to supervised high-intensity interval training or computer gaming skills training, performed twice a week for 12 weeks. Oxygen uptake was measured directly, during a maximum exercise session on a treadmill. PA level were assessed using ActiGraph accelerometer, and body composition was assessed by bioelectrical impedance. ...
TY - JOUR. T1 - Transient increase in femoral arterial blood flow to the contralateral non-exercising limb during one-legged exercise. AU - Yoshizawa, Mutsuko. AU - Shimizu-Okuyama, Shizuyo. AU - Kagaya, Atsuko. PY - 2008/7/1. Y1 - 2008/7/1. N2 - We studied the effect of exercise intensity and duration on blood flow to the non-exercising leg during one-legged dynamic knee extension. Femoral arterial blood flow (FBF) to the non-exercising leg, blood pressure (BP), and heart rate (HR) were monitored during one-legged dynamic knee extension exercise at 15, 30, and 45% maximal voluntary contraction (MVC) in seven healthy females. There was an interaction between exercise intensity and duration for FBF and FVC (P , 0.01). During the initial phase of contralateral leg exercise at all intensities, FBF and femoral vascular conductance (FVC) of non-exercising leg increased, and the increase was larger at higher intensities (P , 0.01). After initial vasodilatation, FBF and FVC decreased to baseline, which ...

There is a high prevalence of women in South Africa with overweight and obesity which is associated with an increased risk of cardiometabolic disorders. Perceived barriers such as lack of time and motivation reduce engagement in beneficial activity behaviours for health. High-intensity interval training (HIIT) is a time-efficient and effective way to improve cardiometabolic risk profile regardless of a loss in body mass or change in body composition. This randomized controlled trial aims to determine the effects on cardiorespiratory fitness, body composition and cardiometabolic health and feasibility of a home-based 14-week HIIT program in women with overweight/obesity or normal body mass. One hundred and twenty women (18-40 years old) with a body mass index between 20 and 35 kg/m2, will be stratified according to their BMI (normal, BMI 20-24.9 kg/m2; or high BMI ≥25 kg/m2) and randomized into a HIIT exercising group (HIIT) or a non-exercising control group (CON). HIIT participants will perform
This study aimed to compare the effects of 8-week self-paced high-intensity interval training (HIIT) vs. self-paced moderate-intensity continuous training (MICT) on the physical performance and psychophysiological responses of young adults. Twenty-eight recreationally active young adults (age: 21.1 +/- 1.6 years) were randomly assigned to either the self-paced HIIT (n = 14) or the MICT (n = 14) group training protocol. The HIIT consisted of two 12-24 x 30 seconds of high-intensity runs interspersed by 30 seconds of recovery. The MICT completed 24-48 minutes of continuous running. Before and after the 8-week interventions the following tests were completed: maximum oxygen consumption (VO2max) estimated from the Yo-Yo Intermittent Recovery Test level 1 (YYIRTL-1), repeated sprint ability (RSA), 10-30-m sprint test, change of direction test (T-drill), countermovement jump (CMI) and squat jump (Si), and triple hop distance test (THD). Training rating of perceived exertion (RPE) and physical activity ...
Monitoring exercise-induced changes in glycemic control in type 2 diabetes. Influence of acute exercise on hyperglycemia in insulin-treated type 2 diabetes
In our study, moderate-intensity aerobic exercise, such as brisk walking, was associated with statistically significant decreases in IGF-I and IGFBP-3. Exercise was also associated with a borderline statistically significant decrease in insulin levels. If we assume the between-group difference in IGF and insulin minimizes the adverse associations among IGF, insulin, and breast cancer risk or prognosis that have recently been reported (1-3), then the beneficial effect of exercise is comparable with that of many commonly used adjuvant chemotherapies (10). The approximate 9% between-group difference in IGF-I levels is clinically meaningful and roughly half the change that has been observed with a 20 mg/d dose of tamoxifen (31).. Whereas three other studies have examined the effect of exercise on insulin (two of the studies also examined IGF) in breast cancer survivors (11-13), only the study conducted by Ligibel and colleagues showed a statistically significant decrease in insulin levels (11). ...
Introduction: Aerobic deconditioning is a major barrier to stroke recovery. Post stroke guidelines recommend moderate intensity continuous exercise (MICE) to improve aerobic fitness and mobility. High-intensity interval training (HIT) has been shown to be more effective than MICE for improving aerobic fitness among healthy adults and persons with heart disease. However, no previous study has compared HIT and MICE among persons with stroke. We hypothesized that HIT would elicit significantly greater improvement in both aerobic fitness and gait function relative to MICE in this population.. Methods: Fourteen subjects (mean ± SD age, 58 ± 10 years; years post stroke, 4.3 ± 2.9) were randomized to HIT (n=11) or MICE (n=5); each 25 min, 3x/week for 4 weeks. HIT involved repeated 30 sec bursts of treadmill (TM) gait at maximum tolerated speed (based on gait stability), alternated with 30-60 sec rest periods. MICE involved continuous TM gait at 45-50% heart rate reserve. Outcomes were measured by a ...
The present study examined the effect of an acute bout of aerobic exercise on sustained attention and discrimination ability in children with LD. With the intensity of exercise confirmed via HR and RPE monitoring, the results demonstrated that a single session of aerobic exercise led to shortened reaction times and improved accuracy rates on the DUAF sustained attention test and the determination test, even as the LD and TD control groups, which did not undergo the exercise session, showed no such improvements. The results provided strong evidence of acute exercise on childrens performance in tasks requiring sustained attention or discriminatory ability, with a high ES (25% of variance explained; Cohen, 1988, p. 287). Also, compared with the TD children who participated in the exercise treatment, the children with LD participating in acute exercise demonstrated greater positive impact in the reaction times and accuracy rates. Our findings suggest that higher accuracy rate and fast reaction time ...
The purpose of this study was to investigate the effect of acute high intensity aerobic training on ANP and Endothelin-1 in inactive obese women. In order to nineteen obese women mean age± SD: 27.94± 3.30, mean weight ±SD: 88.13 ±7.28, mean height ±SD: 163.00± 4.91, mean BMI ±SD: 32.96± 3.13 selected and were randomly allocated to experimental and control groups. Experimental group performed a session acute aerobic exercise on ergometer at intensity 25w that increased every two minute 25w to workload and performed to exhaustion every subject. Samples blood were taken after 12 hours fasting, before and after of program training. For analyzed of biochemical variables used ELISA method and for analyses data used ANOVA. Results of this study showed that acute aerobic training causes significant increase in level of plasma ANP in obese women (p=0.006). But no significant differences observe in plasma level of Endothelin-1. Also, any significant difference didnt observe between pre and ...

Objective: Reactive oxygen species (ROS) have been proposed as signaling molecules mediating exercise training adaptation, but the ROS source has remained unclear. This study aimed to investigate if increased NADPH oxidase (NOX)2-dependent activity during exercise is required for long-term high-intensity interval training (HIIT) in skeletal muscle using a mouse model lacking functional NOX2 complex due to absent p47phox (Ncf1) subunit expression (ncf1* mutation).. Methods: HIIT was investigated after an acute bout of exercise and after a chronic intervention (3x/week for 6 weeks) in wild-type (WT) vs. NOX2 activity-deficient (ncf1*) mice. NOX2 activation during HIIT was measured using an electroporated genetically-encoded biosensor. Immunoblotting and single-fiber microscopy was performed to measure classical exercise-training responsive endpoints in skeletal muscle.. Results: A single bout of HIIT increased NOX2 activity measured as p47-roGFP oxidation immediately after exercise but not 1 h or ...
Low- to moderate-intensity exercise has been widely recommended for people at any age to improve cardiovascular health due to its positive effects on blood lipids and lipoproteins. Recently, many people have been participating in not only low- to moderate-intensity, but high-intensity exercise as well in order to improve their cardiovascular health. However, it is unclear whether high-intensity exercise, particularly resistance exercise, can positively influence blood lipids and lipoproteins. Purpose: The current study examined the effects of low- and high-intensity of resistance exercise on changes in blood lipids and lipoproteins. Methods: In a randomized, cross-over design, 10 healthy recreationally resistance-trained (at least 3 to 6 days per week for a minimum of one year) college-aged men participated in the study. The participants performed a lower body resistance exercise, consisting of the leg press and unilateral knee extension, at two different exercise intensities (low-intensity: 50% of 1-RM
Background Vascular dysfunction is a precursor to the atherosclerotic cascade, significantly increasing susceptibility to cardiovascular events such as myocardial infarction or stroke. Previous studies have revealed a strong relationship between vascular function and cardiorespiratory fitness (CRF). Thus, since high-intensity interval training (HIIT) is a potent method of improving CRF, several small randomized trials have investigated the impact on vascular function of HIIT relative to moderate-intensity continuous training (MICT). Objective The aim of this study was to systematically review the evidence and quantify the impact on vascular function of HIIT compared with MICT. Methods Three electronic databases (PubMed, Embase, and MEDLINE) were searched (until May 2014) for randomized trials comparing the effect of at least 2 weeks ofHIITandMICT on vascular function. HIIT protocols involved predominantly aerobic exercise at a high intensity, interspersed with active or passive recovery periods. We

AU - Snowden, K. AU - Gore, Christopher. PY - 2012/12. Y1 - 2012/12. N2 - A high hemoglobin mass (Hbmass) is associated with a high maximum aerobic power (VO2max), however, the extent to which Hbmass is influenced by training is currently unclear. Accordingly, this study monitored changes in Hbmass and VO2max in 12 previously untrained adults (aged 18-25 years) following 40 days of regular physical activity. Hbmass and VO2max were assessed at the start and end of a 40-day physical activity program, which comprised of approximately 40min of daily, moderate-intensity physical activity. Relative VO2max increased by 11.3%, yet there was no significant change in relative Hbmass (1.7%) and body mass (0.2%) during the 40-day period. There was a significant correlation between Hbmass and VO2max at the start of ...

Purpose: To identify whether the use of active recovery (ACT) the day after high-intensity interval training (HIIT) benefits recovery and to assess whether individual responses to ACT are repeatable. Methods: Eleven well-trained, male intermittent-sport athletes (age: 25.5 ± 1.8 y) completed 4 HIIT sessions, each separated by a 2-week washout period. Of the 4 sessions, 2 were followed by passive recovery (PAS) and 2 by 60 minutes of moderate biking (ACT) 24 hours postexercise in the following sequences: ACT→PAS→ACT→PAS or PAS→ACT→PAS→ACT. Before and after HIIT and after 24 and 48 hours of recovery, maximal voluntary isometric strength (MVIC), countermovement jump height (CMJ), tensiomyographic markers of muscle fatigue (TMG), serum concentration of creatine kinase (CK), muscle soreness (MS), and perceived stress state (PS) were determined. Results: A 3-way repeated-measure analysis of variance with a triple-nested random effects model revealed a significant (P , .05) fatigue-related ...

Background: Recent studies have shown that increased circulating levels of adiponectin (AD) and high sensitive C reactive protein (hs-CRP) were associated with higher mortality in chronic heart failure (CHF) patients (pts). Exercise training improves functional capacity, however, there are concerns regarding what exercise training intensity is better to improve inflammatory markers and overload hormones evaluated by brain natriuretic peptide (BNP) in CHF.. Methods: 30 men, 54 ± 2 yrs (mean ± se), with non-ischemic dilated cardiomyopathy, functional class II-III, LVEF 28 ± 1%, peak oxygen consumption (VO2) = 17,4 ± 0,6 ml/kg/min were randomized into 3 groups: low intensity exercise training (LO) - 9 pts, high intensity exercise training (HI) -11 pts, and control (CO) - 10 pts, under optimal medical treatment. At baseline and at 6 months, all pts underwent maximal treadmill cardiopulmonary exercise testing, rest and peak BNP, rest hs-CRP and AD level and rest echocardiography (echo). Low ...

We identified 10 cohort studies on physical activity of moderate intensity and risk of type 2 diabetes, including a total of 301,221 participants and 9,367 incident cases. Table 1 shows the characteristics of the included studies. Fig. 1 shows the results for moderately intense physical activity and risk of type 2 diabetes with and without adjustment for BMI. For one study only BMI-unadjusted (13) and for one study only BMI-adjusted estimates were presented (22). The summary RR of type 2 diabetes without BMI adjustment was 0.69 (95% CI 0.58-0.83) for the highest as compared with the lowest category of moderate-intensity physical activity. The BMI-adjusted RR of diabetes was 0.83 (0.76-0.90). The P value for heterogeneity in study results was ,0.001 for the BMI-unadjusted and 0.24 for the BMI-adjusted estimates.. In five of the cohort studies the specific role of walking was examined (13,15,19,21,22). Figure 2 shows the results for walking and risk of type 2 diabetes. The BMI-unadjusted summary ...
While there are compelling observational data confirming that individuals who exercise are healthier, the efficacy of aerobic exercise interventions to reduce metabolic risk and improve insulin sensitivity in older people has not been fully elucidated. Furthermore, while low birth weight has been shown to predict adverse health outcomes later in life, its influence on the response to aerobic exercise is unknown. Our primary objective is to assess the efficacy of a fully supervised twelve week aerobic exercise intervention in reducing clustered metabolic risk in healthy older adults. A secondary objective is to determine the influence of low birth weight on the response to exercise in this group.We aim to recruit 100 participants born between 1931-1939, from the Hertfordshire Cohort Study and randomly assign them to no intervention or to 36 fully supervised one hour sessions on a cycle ergometer, over twelve weeks.

Background: With improved survival rates, there are growing numbers of cancer survivors. These individuals report impaired physical functioning, anxiety and depressed mood, fatigue, and reduced quality of life after treatment. In addition, they may be at increased risk for cardiovascular disease, obesity, osteoporosis and future cancers. Prior research has demonstrated that moderate-intensity physical activity (PA) can improve enhance physical functioning, reduce fatigue and improve vigor among cancer patients and those who have completed medical treatments. These efforts have not been integrated with the healthcare system. Data support the role of primary care providers in promoting PA among their sedentary patients; the role of oncologists in encouraging patients to become physically active has not been examined.. Objectives: This study aims at testing the efficacy of a PA intervention in an outpatient oncology setting. We plan to compare Brief Advice for PA (MD advice plus contact control) ...

Adults -- Adults gain substantial health benefits from two and one half hours a week of moderate intensity aerobic physical activity, or one hour and 15 minutes of vigorous physical activity. Walking briskly, water aerobics, ballroom dancing and general gardening are examples of moderate intensity aerobic activities. Vigorous intensity aerobic activities include racewalking, jogging or running, swimming laps, jumping rope and hiking uphill or with a heavy backpack. Aerobic activity should be performed in episodes of at least 10 minutes. For more extensive health benefits, adults should increase their aerobic physical activity to five hours a week moderate-intensity or two and one half hours a week of vigorous-intensity aerobic physical activity. Adults should incorporate muscle strengthening activities, such as weight training, push-ups, sit-ups and carrying heavy loads or heavy gardening, at least two days a week ...
High-intensity interval training (HIIT) helps to improve a person s fitness by decreasing exercise time and by simultaneously increasing metabolism.
Both weight training and exercise affect the production of ghrelin, but only aerobic exercise affects the role of peptide. As a result, aerobic exercise generally has a stronger effect on decreasing hunger.. Anaerobic vs. aerobic. Lets start with a definition of aerobic and anaerobic exercises. Aerobic exercises are exercises that are vigorous and require a lot of air. Anaerobic exercises require less cardiovascular effort and more intramuscular effort.. So basically, aerobic exercises include activities like running, walking, bicycling and swimming. Anaerobic exercises mostly involve weight training, sit-ups and pushups.. Generally, aerobic exercise is the type of exercise turned to in order to lose weight. But the obese will lose the most weight if they combine both anaerobic and aerobic exercises.. This is because muscles must pull calories away from the body in order to continue to grow and repair themselves.. Unless youre eating several hamburgers a day, your muscles will eventually need ...
The purpose of this study was to examine the impact of acute high-intensity interval training (HIIT) compared with continuous moderate-intensity (CMI) exercise on postprandial hyperglycemia in overweight or obese adults. Ten inactive, overweight or obese adults (41 ± 11 yrs, BMI = 36 ± 7 kg/m2) performed an acute bout of HIIT (10 × 1 min at approximately 90% peak heart rate (HRpeak) with 1-min recovery periods) or matched work CMI (30 min at approximately 65% HRpeak) in a randomized, counterbalanced fashion. Exercise was performed 2 h after breakfast, and glucose control was assessed by continuous glucose monitoring under standardized dietary conditions over 24 h. Postprandial glucose (PPG) responses to lunch, dinner, and the following days breakfast were analyzed and compared with a no-exercise control day. Exercise did not affect the PPG responses to lunch, but performing both HIIT and CMI in the morning significantly reduced the PPG incremental area under the curve (AUC) following dinner ...
Aerobic Exercise Training May Not Offset the Pro-inflammatory Effects of a High Fat Feeding. Katie C. Carpenter, Lisa Esposito, Kelley A. Strohacker, Richard J. Simpson, Brian K. McFarlin. University of Houston, Houston, TX Increased adiposity is associated with an increase in systemic inflammation, which is involved in the pathophysiology of various disease states. A current hypothesis in our laboratory suggests that the toll-like receptor 4 (TLR4) pathway may link physical activity and systemic inflammation. PURPOSE: The primary purpose was to determine if 6-weeks of aerobic exercise training (5 days per week, 1 hour per day. 21-22m/min) would limit the increase in systemic inflammation resulting from high-fat (60% of calories from fat) feeding. A secondary purpose was to determine if changes in cell-surface TLR4 expression would account for observed differences in inflammatory status between mice which exercise and those that remain sedentary. METHODS: 36 CD-1 male mice were randomly assigned to one

High-intensity interval training has a multitude of health benefits. Can it even slow cellular aging? Heres what new research shows.
1. Regular aerobic exercise causes cardiovascular, neural, humoral and metabolic changes. Many of these are likely to influence cardiovascular risk and the changes vary according to the level and duration of increased physical activity.. 2. The case for exercise exerting beneficial effects derives from epidemiological data showing that sedentary subjects have, on average, double the risk of cardiovascular disease of active individuals. Post-infarct rehabilitation studies are also consistent with a beneficial effect of exercise. Large randomized controlled intervention studies have not been performed.. 3. These benefits may be due to the effects of regular exercise on risk factors, direct effects on atheromatous vessels, or improvement in survivability in established coronary heart disease by reducing arrythmias or increasing tolerance of ischaemia.. 4. There are direct effects of regular exercise on blood pressure (BP) and lipid profiles. These occur at different levels of physical activity. ...

Perhaps it should be, because physical activity can be a valuable tool for controlling COVID-19 infections and maintaining quality of life. Physical activity is one of the most powerful forces for good health. Physical activity helps prevent and/or treat many physical and mental health conditions by improving functioning of numerous physiological systems. (Powell et al., 2018) In this piece we explain how harnessing the salutogenic power of physical activity could help ease the consequences of the coronavirus pandemic in four ways. First, physical activity has potential to reduce the severity of COVID-19 infections. This is related to what happens in the lungs during an infection. The immune system detects the virus invader in the lungs and attacks it. The conflict between the virus and immune cells creates ...

Title: Alberta physical activity and breast cancer prevention trial: sex hormone changes in a year-long exercise intervention among postmenopausal women.. Journal: J Clin Oncol 28(9):1458-66. Date: 2010 Mar 20. Abstract: PURPOSE: We examined how an aerobic exercise intervention influenced circulating estradiol, estrone, sex hormone-binding globulin (SHBG), androstenedione, and testosterone levels, which may be involved in the association between physical activity and breast cancer risk. METHODS: A two-center, two-arm randomized controlled trial of exercise was conducted in 320 postmenopausal, sedentary women age 50 to 74 years. Participants were randomly assigned to a 1-year aerobic exercise intervention of 225 min/wk (n = 160) or to a control group who maintained their usual level of ...
