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.

Book High Intensity Exercise in Hypoxia Beneficial Aspects and Potential Drawbacks

Download or read book High Intensity Exercise in Hypoxia Beneficial Aspects and Potential Drawbacks written by Olivier Girard and published by Frontiers Media SA. 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.

This book was released on 2011 with total page 58 pages. Available in PDF, EPUB and Kindle. 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

Book Excess Post exercise Oxygen Consumption Response to a Bout of Resistance Exercise

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.
