Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to evaluate the exercise intensity and energy expenditure of interval exercise compared to steady-state exercise on a cycle ergometer. Fourteen subjects completed a VO2max test on a cycle ergometer to determine their aerobic capacity. Subjects then completed an interval ride and a steady-state ride. The interval ride alternated one minute of high-intensity cycling at 90% of maximal power output followed by one minute of active rest for 20 minutes. The steady-state ride consisted of 20 minutes exercise at 90% of the subject's ventilatory threshold (VT). Total work was matched between conditions. Oxygen consumption (V02), heart rate (HR), lactate, and RPE values were measured. After completion of both trials, a post-exercise questionnaire was administered. No significant difference (p

This book was released on 2014 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to investigate the correlation between improvements in aerobic and anaerobic power with various acute physiological responses, including blood lactate accumulation (HLa), percent heart rate reserve (%HRR), Rating of Perceived Exertion (RPE), session RPE (sRPE), and the training impulse (TRIMP) during high intensity interval training (HIIT) compared to moderate intensity interval training and continuous training. Fifty-five subjects aged 18 to 29 completed a pre and post VO2max and Wingate test on the cycle ergometer. Subjects completed 24 sessions of either a steady-state exercise control at 90% of the power output (PO) at the ventilatory threshold (VT), a Meyer interval protocol with 30:60 seconds exercise-to-rest ratio at 100% of peak power output (PPO), or a Tabata interval protocol with 20:10 seconds exercise-to-rest ratio at 170% of VO2max.

Available in PDF, EPUB and Kindle. Book excerpt: 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. That’s 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.

This book was released on 2014 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: High intensity interval training (HIIT) has become an increasingly popular exercise phenomenon due to its cardiovascular effect and short duration. The purpose of this study was to compare the effects of two HIIT protocols and a steady-state protocol on aerobic capacity following an 8-week training period. Methods: Fifty-five untrained college-aged subjects (17 male, 38 female) were randomly assigned to one of the three training groups (steady-state, Tabata, or Meyer). The steady-state group (n=19) completed 20 minutes of exercise at 90% of ventilatory threshold. The Tabata group (n=21) completed eight intervals of 20 seconds at 170% VO2max, with 10 seconds rest in between each bout. The Meyer group (n=15) completed 13 sets of 30 seconds at 100% of the PPO at VO2max, with 60 seconds of active rest, yielding an output average of 90% of ventilatory threshold. Each subject completed 24 training sessions. Results: Significant increases in VO2max and Peak Power Output for each training group, with no significant differences between groups. There were no significant changes in maximal HR for any training group over the course of the study. The results of this study suggest that steadystate, Tabata, and Meyer protocols elicit similar increases in aerobic capacity.

Download or read book High Intensity Interval Training Vs Steady State Exercise and Relation to Post exercise Hypotension written by Brianna Roberts and published by . This book was released on 2014 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: High intensity interval training has become popular to produce various physiological benefits. There is much controversy over what type of interval training has the greatest effects. Purpose: This study was designed to compare high intensity interval groups to examine levels of post-exercise hypotension (PEH). Methods: Young, healthy volunteers (N=55) performed 24 workout sessions on a stationary bike over an 8 week period. Subjects were randomly placed into three different exercise groups: Tabata, Meyer, and steady state. Tabata (N=21) performed 20 seconds at 170% power output (PO) of VO2 max and 10 second rest for 8 bouts. Meyer (N=15) performed 30 seconds at 100% PO of VO2 max, with 60 seconds active recovery, for a total of 20 minutes. Steady state (N=19) performed 20 minutes of exercise at 90% ventilatory threshold (VT). Blood pressures were measured once a week and multiple times during those sessions. Measurements of PEH were taken 30 minutes after exercise. Results: There were significant differences in systolic blood pressure (SBP) between pre- and post-exercise but no significant differences between the three exercise groups. Averaged over eight weeks, steady state had PEH of 9.1 + 2.17, Meyer showed PEH of 8.3 + 1.83 while Tabata had PEH of 9.1 + 1.55. There was no significant difference in PEH between the weeks. Conclusions: Through this study, we have concluded that PEH occurs in SBP 30 minutes after exercise, regardless of exercise intensity. During the eight week training, PEH remained constant. Previous findings have concluded similar results, including studies involving blood pressure medication.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the study was to determine whether steady state exercise (SSE) or high intensity interval exercise (HIIE) would better improve energy expenditure (EE) during 90 minutes of excess post exercise oxygen consumption (EPOC) while attempting to match EE between both exercise protocols. We also wanted to examine physiological changes during post exercise measurements, which included VO2, RER, VE and HR. Twelve males aged between 19 and 24 were assigned to the SSE and HIIE conditions. A VO2max and a 30s-all-out sprint set at 150% of maximum workload was performed on a cycling ergometer interspersed by 5 minutes to ensure sufficient recovery time. Participants randomly completed SSE or HIIE followed by 90 minutes of EPOC. A gross efficiency (GE) of 18% was used in order to best quantify the anaerobic attributable EE during the HIIE in order to estimate total EE. Our results indicate that the HIIE expended less EE than SSE and from our pre-test EE estimations (p

Available in PDF, EPUB and Kindle. Book excerpt: Exercise-Cognition Interaction: Neuroscience Perspectives is the only book on the market that examines the neuroscientific correlation between exercise and cognitive functioning. The upsurge in research in recent years has confirmed that cognitive-psychology theory cannot account for the effects of exercise on cognition, and both acute and chronic exercise effect neurochemical and psychophysiological changes in the brain that, in turn, affect cognitive functioning. This book provides an overview of the research into these effects, from theoretical research through current studies that emphasize neuroscientific theories and rationales. It addition, users will find a thorough examination of the effects of exercise interventions on cognitive functioning in special populations, including the elderly, children, and those suffering from a variety of diseases, including schizophrenia, diabetes, and an array of neurological disorders. With contributions from leading researchers in the field, this book will be the go-to resource for neuroscientists, psychologists, medical professionals, and other researchers who need an understanding of the role exercise plays in cognitive functioning. Provides a comprehensive account of how exercise affects brain functioning, which in turn affects cognition Covers both theory and empirical research Presents a thorough examination of the effects of exercise interventions on cognitive functioning in special populations, including the elderly, children, and those suffering from a variety of diseases Examines neurochemical, psychophysiological, and genetic factors Covers acute and chronic exercise

Download or read book Effects of Exercise on Hypertension written by Linda S. Pescatello and published by Springer. This book was released on 2015-07-08 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.

Download or read book Perceived Exertion Laboratory Manual written by Luke Haile and published by Springer. This book was released on 2014-11-07 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​ ​This manual provides laboratory-based learning experiences in perceptually and psychosocially linked exercise assessment, prescription, and programming. The primary pedagogic outcome is the ability to use applied theory and practice in perceptual and psychosocial exercise assessment and program design to promote the adoption and maintenance of a physically active lifestyle, enhancing overall health fitness. Perceptual and psychosocial variables are presented in individual, stand-alone laboratory modules that can supplement existing curricula such as exercise and sport psychology, exercise physiology, exercise testing and prescription, and exercise training and conditioning. In addition, the complete modular set has a conceptual flow that allows its presentation as an entire, laboratory-based course. The laboratory modules are divided into three primary units: assessment (theoretical constructs, scales and procedures, tests), prescription (self-regulation, performance), and program evaluation. The manual uses a unique format in which case studies are embedded in the conceptual flow of each lab module facilitating translation of laboratory results to real-world application. The manual concludes with a discussion of perceptually and psychosocially linked exercise prescription and programming applications in public health, such as program monitoring and adherence.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This study compared the acute cardiopulmonary and metabolic effects of four high-intensity interval training (HIIT) protocols using varying intensities during the work and recovery periods. Eleven participants (5 males, 6 females) performed four, 20-minute HIIT protocols at a 1:1 "work:recovery" ratio on a cycle ergometer in random order. The work:recovery relative intensities, based upon previously determined maximum work rates, were: 80%:0%, 80%:50%, 100%:0%, and 100%:50%. Oxygen uptake, heart rate, blood lactate, and rating of perceived exertion were measured. Data were analyzed using a two-way, repeated measures ANOVA (p ≤ 0.05). Oxygen uptake and heart rate were expressed as a percentage of the peak values established during a prior graded exercise test. There were clear differences in physiological response between protocols. The 80:50 and 100:0 may produce the best combination of effects. The 100:50 produced the greatest physiological response, however, it may not be practical for the general population.

Download or read book The Effect of Different Interval Durations on Measures of Exercise Intensity written by Lauri A. Hrovatin and published by . This book was released on 1999 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring training loads during continuous exercise has been validated, however given the importance of interval training, this method (RPE * duration) has not been validated during interval training of different durations. Twelve well trained individuals (m = 6, f = 6) performed an incremental cycle ergometer test to failure and four randomly ordered 30 min tests on a Icde cycle. The four tests were steady state, 30-sec. I-min, and 2-min. with a work relief ratio of 1:1. Workloads were calculated according to the individual anaerobic thresliold (IAT) and physiological variables (HR, RPE, BLa, and VO2) were measured every 10-min. RPE was also acquired 30-min after the exercise bout and multiplied by the duration to obtain a session RPE score. Heart rate data were collected from a Polar Heart Rate Monitor and a summated HR score was calculated. All of the physiological variables behaved similarly during interval training and steady state training by rising from rest to 10-min and then leveling off. The session RPE score and summatcd HR score were compared and found to be closely related suggesting that the summated I-IR score and session RPE are essentially the same. In conclusion, the session I

Download or read book Post Exercise Recovery Fundamental and Interventional Physiology written by Sergej M. Ostojic and published by Frontiers Media SA. This book was released on 2016-05-25 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological responses after maximal and submaximal exercise are routinely monitored in a plethora of diseases (e.g. cardiovascular diseases, cancer, diabetes, asthma, neuromuscular disorders), and normal populations (e.g. athletes, youth, elderly), while slower or irregular post-exercise recovery usually indicates poor health and/or low fitness level. Abnormal post-exercise recovery (as assessed via blunted post-exercise heart rate dynamics) helps to predict the presence and severity of coronary artery disease, while differences in recovery outcomes in athletes might discriminate between fit and unfit individuals. Disturbances in post-exercise recovery might be due to acute or persistent changes in: (1) adaptive responses mediated by the autonomic nervous system and vasodilator substances, (2) cellular bioenergetics, and/or (3) muscular plasticity. Preliminary evidence suggests possible role of time-dependent modulation of nitric oxide synthase and adenosine receptors during post-exercise recovery, yet no molecular attributes of post-exercise recovery are revealed so far. Currently several markers of post-exercise recovery are used (e.g. heart rate measures, hormone profiles, biochemical and hematological indices); however none of them meets all criteria to make its use generally accepted as the gold standard. In addition, recent studies suggest that different pharmacological agents and dietary interventions, or manipulative actions (e.g. massage, cold-water immersion, compression garments, athletic training) administered before, during or immediately after exercise could positively affect post-exercise recovery. There is a growing interest to provide more evidence-based data concerning the effectiveness and safety of traditional and novel interventions to affect post-exercise recovery. The goals of this research topic are to critically evaluate the current advances on mechanisms and clinical implications of post-exercise recovery, and to summarize recent experimental data from interventional studies. This knowledge may help to identify the hierarchy of key mechanisms, and recognize methods to monitor and improve post-exercise recovery in both health and disease.
