Cardiorespiratory Adaptations during Concurrent Aerobic and Strength Training in Men and Women
نویسندگان
چکیده
This study investigated the effects of endurance followed by strength training (ES, men n = 16; women n = 15), the reverse exercise order (SE, men n = 18, women n = 13) and concurrent endurance and strength training performed on alternating days (AD, men n = 21, women n = 18) on cardiorespiratory parameters. Peak oxygen consumption ([Formula: see text]O2peak) and oxygen consumption at sub-maximal power outputs ([Formula: see text]O2submax) of 50 to 175 Watts in men and 50 to 125 Watts in women were assessed during an incremental cycling test both before and after 24 weeks of training. Increases in [Formula: see text]O2peak in both men and women were statistically larger in AD (18±9% and 25±11%) compared to ES (7±9% and 12±12%, p = 0.002 and 0.009, respectively) and SE (7±9% and 10±8%, p = 0.005 and 0.008, respectively). No statistical group interaction was observed for [Formula: see text]O2submax in men, but in women [Formula: see text]O2submax was statistically lower at week 24 in ES compared to AD at 75 W (-2±6% vs. +3±6%, p = 0.027) and 125 W (-4±5% vs. +2±5%, p = 0.010). These findings indicate that endurance and strength training performed on alternating days may optimize the adaptations in [Formula: see text]O2peak in both sexes, while performing ES training in women may optimize cardiorespiratory fitness at sub-maximal power outputs.

Effect of Concurrent Training Order With Electromyostimulation on Physical Performance in Young Elderly Women
Introduction: Aging is one of the stages of life that needs special attention due to the special conditions of this period of life. Inactivity and myasthenia due to aging are important factors in reducing the physical and functional readiness of the elderly, which can reduce their quality of life. On the other hand, electromyostimulation (EMS) is one of the modern training methods that can be s...
