This book was released on 2008 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess post-exercise oxygen consumption (EPOC) is defined as an increase in oxygen consumption (VO2) following the completion of exercise. Previous research has primarily focused on the influence of endurance-type exercise on EPOC. Therefore, the purpose of this study was to compare the effect of a light versus heavy resistance exercise protocol of equal work on EPOC. Ten male subjects performed two days of one-repetition maximum (1-RM) testing and two experimental trials (Light: 3 sets of 15 repetitions at 40% 1-RM; Heavy: 4 sets of 4 to 8 repetitions at 80 to 87.5% 1-RM). VO2, caloric expenditure, blood lactate concentration, heart rate, and blood pressure were measured at baseline, 5, 15, 30, 60, 90 and 120 minutes post-exercise, and 24 hours post-exercise. For both exercise protocols, VO2 and caloric expenditure were significantly greater at 5 min post-exercise compared to baseline. In addition, at 5 min post-exercise, VO2 and caloric expenditure were greater during the light protocol compared to the heavy protocol. During the 120 minutes post exercise, there was no significant difference in EPOC (44.0 ± 43 and 39.1 ± 44.3 mL kg−1; P=0.786) or total caloric expenditure (15.1 ± 13.8 and 12.9 ± 16.9 kcal; P=0.742) between the light and heavy protocols. The data suggests that for resistance exercise protocols with an equal work volume, there is no difference in the magnitude and duration of EPOC.

This book was released on 2018-01-25 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, ‘traditional’ moderate-intensity continuous training (60-75% peak heart rate) was the type of physical activity most frequently recommended for both athletes and clinical populations (cf. American College of Sports Medicine guidelines). However, growing evidence indicates that high-intensity interval training (80-100% peak heart rate) could actually be associated with larger cardiorespiratory fitness and metabolic function benefits and, thereby, physical performance gains for athletes. Similarly, recent data in obese and hypertensive individuals indicate that various mechanisms – further improvement in endothelial function, reductions in sympathetic neural activity, or in arterial stiffness – might be involved in the larger cardiovascular protective effects associated with training at high exercise intensities. Concerning hypoxic training, similar trends have been observed from ‘traditional’ prolonged altitude sojourns (‘Live High Train High’ or ‘Live High Train Low’), which result in increased hemoglobin mass and blood carrying capacity. Recent innovative ‘Live Low Train High’ methods (‘Resistance Training in Hypoxia’ or ‘Repeated Sprint Training in Hypoxia’) have resulted in peripheral adaptations, such as hypertrophy or delay in muscle fatigue. Other interventions inducing peripheral hypoxia, such as vascular occlusion during endurance/resistance training or remote ischemic preconditioning (i.e. succession of ischemia/reperfusion episodes), have been proposed as methods for improving subsequent exercise performance or altitude tolerance (e.g. reduced severity of acute-mountain sickness symptoms). Postulated mechanisms behind these metabolic, neuro-humoral, hemodynamics, and systemic adaptations include stimulation of nitric oxide synthase, increase in anti-oxidant enzymes, and down-regulation of pro-inflammatory cytokines, although the amount of evidence is not yet significant enough. Improved O2 delivery/utilization conferred by hypoxic training interventions might also be effective in preventing and treating cardiovascular diseases, as well as contributing to improve exercise tolerance and health status of patients. For example, in obese subjects, combining exercise with hypoxic exposure enhances the negative energy balance, which further reduces weight and improves cardio-metabolic health. In hypertensive patients, the larger lowering of blood pressure through the endothelial nitric oxide synthase pathway and the associated compensatory vasodilation is taken to reflect the superiority of exercising in hypoxia compared to normoxia. A hypoxic stimulus, in addition to exercise at high vs. moderate intensity, has the potential to further ameliorate various aspects of the vascular function, as observed in healthy populations. This may have clinical implications for the reduction of cardiovascular risks. Key open questions are therefore of interest for patients suffering from chronic vascular or cellular hypoxia (e.g. work-rest or ischemia/reperfusion intermittent pattern; exercise intensity; hypoxic severity and exposure duration; type of hypoxia (normobaric vs. hypobaric); health risks; magnitude and maintenance of the benefits). Outside any potential beneficial effects of exercising in O2-deprived environments, there may also be long-term adverse consequences of chronic intermittent severe hypoxia. Sleep apnea syndrome, for instance, leads to oxidative stress and the production of reactive oxygen species, and ultimately systemic inflammation. Postulated pathophysiological changes associated with intermittent hypoxic exposure include alteration in baroreflex activity, increase in pulmonary arterial pressure and hematocrit, changes in heart structure and function, and an alteration in endothelial-dependent vasodilation in cerebral and muscular arteries. There is a need to explore the combination of exercising in hypoxia and association of hypertension, developmental defects, neuro-pathological and neuro-cognitive deficits, enhanced susceptibility to oxidative injury, and possibly increased myocardial and cerebral infarction in individuals sensitive to hypoxic stress. The aim of this Research Topic is to shed more light on the transcriptional, vascular, hemodynamics, neuro-humoral, and systemic consequences of training at high intensities under various hypoxic conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

This book was released on 2001 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: To examine the excess postexercise oxygen consumption (EPOC) response following a bout of heavy resistance exercise (HRE), seven healthy males (age = 22 f 3 yr; height = 177 -+ 8 cm; mass = 83 f 10 kg, percent body fat = 10.4 f 4.2%) who weight trained recreationaly, engaged in a 31-minute bout of HRE. The bout consisted of four circuits of bench press, power cleans, and squats, selected to recruit most major muscle groups. Each set was performed using the subject's predetmnined ten-repetition maximum and continued until failure. Each set was followed by a two-minute rest interval. Oxygen consumption (Va)m measurements were obtained at regular intervals throughout the day, before and after HRE (34 h pm, 29 h pre, 24 h pre, 10 h pre, 5 h pre, immediate post, 14 h post, 19 h post, 24 h post, 38 h post, 43 h post, 48 h post). Postexercise V02 measurements were compared to the baseline measurements that corresponded with the same time of day. A repeated measures ANOVA revealed that EPOC was significantly elevated @ 5 0.05) immediately, 14.19, and 38 hours post-exercise. Mean daily V q values for both post-exercise days were also significantly elevated above the baseline day. These results suggest that EPOC duration and magnitude following HRE may exceed the EPOC produced by following moderate aerobic exercise. Furthermore, the cumulative energy expenditure as a result of EPOC following HRE may exceed the combined total energy expended during and after aerobic exercise.
Book Synopsis Differences in Excess Post-exercise Oxygen Consumption (EPOC) After Reduced Exertion High-intensity Interval Training (REHIT) on the Cycle Ergometer and Rowing Ergometer by : Rasmus D. Clausen

Clausen and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Reduced exertion high intensity interval training (REHIT) is a form of sprint interval training (SIT) with extremely low volume that increases maximal oxygen uptake (V̇O2max) and reduces body fat with as little as 10 minutes of exercise per session. However, REHIT is rarely studied on other modalities than the cycle ergometer, on which SIT is often associated with feelings of displeasure and low enjoyment. The purpose of this study was to examine the differences in oxygen consumption (V̇O2), ventilation (V̇E), EPOC, energy expenditure (EE), and blood lactate concentration (BLa) in response to REHIT performed on the cycle ergometer and rowing ergometer. Methods: Eight habitually active men and women (age = 29 ± 9 yr) initially completed two assessments of maximal oxygen uptake at least 24 hours apart. Subsequently on two separate days, participants completed REHIT consisting of three 20 s "all-out" sprints on the cycle-ergometer (REHIT-CYC) and rowing ergometer (REHIT-ROW), followed by 60 minutes of rest during which gas exchange data and BLa were measured. Results: V̇O2 increased significantly in response to REHIT (0.18 ± 0.04 L/min vs. 1.11 ± 0.21 L/min and 0.18 ± 0.04 L/min vs. 1.35 ± 0.30 L/min, p 0.001) and remained elevated for 15 minutes post-exercise in both modalities (0.31 ± 0.07 L/min and 0.30 ± 0.06 L/min, p

Book excerpt: ABSTRACT: The present study sought to determine the effects of order of intensity presentation on fuel selection and excess post-exercise oxygen consumption (EPOC) during and following dual-intensity exercise. Eight males (mean +- SD: age = 23+- 3 years, peak oxygen consumption [VO2] = 47.7 +- 2.5 ml. kg-1 . min-1, weight = 74 +- 7 kg) completed a VO2 peak test and two submaximal trials. Trials consisted of 15 min of high-intensity (75% VO2 peak) and 15 min of low-intensity (50% VO2 peak) running. The researcher measured baseline VO2 during the final 10 min of a 30-min rest period prior to each trial and heart rate (HR; beats/min), respiratory exchange ratio (RER), expired ventilation (VE; L/min) and rating of perceived exertion (RPE) during and following each trial. When subjects began with the greater intensity (Hi-Lo), the researcher observed a lower (p
