Sex differences in the cardiorespiratory and hemodynamic response to exercise exist due to differences in heart size, blood volume, and hemoglobin mass, eliciting a higher maximal oxygen uptake (VO2max) in men versus women. Data are equivocal on whether sex differences in training responsiveness occur. This study investigated potential sex differences in the hemodynamic response (stroke volume (SV) and cardiac output (CO)) to high intensity interval exercise (HIIE). Habitually active men (n=15) and women (n=13) underwent VO2max testing, followed by three HIIE sessions consisting of the 4X4, 10X1, and reduced exertion high intensity training (REHIT), whose order was randomized. During exercise, oxygen uptake (VO2) and hemodynamic responses were determined. Results showed no sex difference in peak relative VO2 (p=0.263), CO (p=0.277), or SV (p=0.116), although absolute values were higher in men (p0.05). Peak absolute (127.3 ± 20.6 vs. 115.2 ± 16.6 mL/beat, p=0.004, d=0.66) and relative SV (111.0 ± 15.5 vs. 100.7 ± 11.1 %max, p=0.005, d=0.78) were higher with REHIT versus 4X4. No sex differences in mean relative VO2, CO, or SV occurred (p0.05). Data showed lower mean VO2 during REHIT versus 4X4 (59.3 ± 6.8 vs. 65.8 ± 5.8 %VO2max, p

Peak diastolic blood pressure (DBP) responses to resting bursts of muscle sympathetic nerve activity (MSNA; sympathetic transduction) are inversely associated with aerobic fitness in young males, but not females. I tested the hypothesis that 12- weeks of high-intensity interval training (HIIT) would improve aerobic fitness in young, healthy adults, but only attenuate sympathetic transduction in males. Aerobic fitness (V̇ O2peak, via indirect calorimetry), as well as peroneal MSNA (microneurography), and DBP (finger photoplethysmography) were recorded for ~10-min during supine rest. HIIT improved absolute V̇ O2peak in both sexes (both, P≤ 0.004), with greater increases observed in males (P=0.004). There was no change in sympathetic transduction following HIIT for either sex (both, P≥0.523). However, nadir DBP responses following cardiac cycles absent of MSNA bursts were enhanced (more negative) following HIIT in females (group P=0.019, females P=0.016, males P=0.345). These results indicate that HIIT mediated increases in aerobic fitness did not alter sympathetic transduction in a group of younger males and females.

This text discusses how theoretical and applied aspects of exercise testing and exercise prescription must be modified due to the restrictions and/or limitations created by a specific health state. Topics covered include: general principles of exercise testing and exercise prescription; discussion of the importance of such general factors as age, gender, and environment; specific health states, general treatment, risk factors, how it may affect and be affected by exercise; how to modify exercise testing procedures; how to prescribe exercise; and the effects from exercise programs.

Sex and Cardiac Electrophysiology: Differences in Cardiac Electrical Disorders Between Men and Women is a comprehensive investigation into all aspects of sex differences in cardiac electrophysiology. As there are substantial differences between female and male patients in physiology, pathology triggering factors, disease progression, clinical approaches and treatment outcome, this book provides a comprehensive examination. In cardiology, the differences between women and men are more recognized, hence this title summarizes these important differences, providing the essential information needed for clinical specialists and researchers involved in the design and implementation of clinical studies. Explores topics ranging from the physiologic differences between women and men to the differences in clinical handling of arrhythmic disorders between female and male patients Provides sex differences in cardiac electrophysiology in separate chapters Covers the sex differences of cardiac electrical disorders, providing insights beyond cardiac metabolic syndrome, hypertension, atherogenesis and heart failure

Updated for its Fourth Edition with increased art and photos, this undergraduate exercise physiology textbook integrates basic exercise physiology with research studies to stimulate learning, allowing readers to apply principles in the widest variety of exercise and sport science careers. The book has comprehensive coverage, including integrated material on special populations, and a flexible organization of independent units, so instructors can teach according to their preferred approach. Each unit is designed with a consistent and comprehensive sequence of presentation: basic anatomy and physiology, the measurement and meaning of variables important to understanding exercise physiology, exercise responses, training principles, and special applications, problems, and considerations. Plowman & Smith provides a consistently organized, comprehensive approach to Exercise Physiology with excellent supporting ancillary materials. Its ability to relate up to date research to key concepts and integrate special populations makes this book ideal for classroom use.

This report from the Committee on Military Nutrition Research reviews the history of caffeine usage, the metabolism of caffeine, and its physiological effects. The effects of caffeine on physical performance, cognitive function and alertness, and alleviation of sleep deprivation impairments are discussed in light of recent scientific literature. The impact of caffeine consumption on various aspects of health, including cardiovascular disease, reproduction, bone mineral density, and fluid homeostasis are reviewed. The behavioral effects of caffeine are also discussed, including the effect of caffeine on reaction to stress, withdrawal effects, and detrimental effects of high intakes. The amounts of caffeine found to enhance vigilance and reaction time consistently are reviewed and recommendations are made with respect to amounts of caffeine appropriate for maintaining alertness of military personnel during field operations. Recommendations are also provided on the need for appropriate labeling of caffeine-containing supplements, and education of military personnel on the use of these supplements. A brief review of some alternatives to caffeine is also provided.
