摘要

本研究旨在比较有和无血流限制(BFR)的有氧运动和体重抵抗运动对急性心血管和代谢的反应。久坐不动的人(8名男性,6名女性)参加了4个随机运动阶段:有BFR的步行、没有BFR的步行、有BFR的步行弓步和没有BFR的步行弓步。步行试验包括15分钟5公里/小时的速度,而步行弓步包括4组重复(30,16,16,16)。在60%的肢体闭塞压力下应用BFR。与步行(47% V˙O2 max, 61% HRmax)相比,步行弓步的代谢和心脏反应更高(57% V˙O2 max, 66% HRmax)。BFR的应用同样提高了步行弓步(BFR: 60% V˙O2 max, 70% HRmax)和步行(BFR: 53% V˙O2 max, 63% HRmax)的反应。这些相似的反应表明,体重步行弓步也可以被认为是有氧运动,就像步行一样。鉴于有氧步行和体重步行弓步之间的反应相似,并且与非BFR相比,BFR显著增强了这两种运动模式的反应,这些研究结果表明,从业者在选择有氧BFR运动模式时具有一定的灵活性,这些模式可能更适合个体。

Acute responses to aerobic and bodyweight exercises with and without blood flow restriction in sedentary individuals - A randomized crossover study.

This study aimed to compare the acute cardiovascular and metabolic responses to aerobic and bodyweight resistance exercises, both with and without blood flow restriction (BFR). Sedentary individuals (8 males, 6 females) participated in four randomized exercise sessions: walking with BFR, walking without BFR, walking lunges with BFR, and walking lunges without BFR. Walking trials involved 15 minutes at 5 km.h-1, while walking lunges comprised four repetition sets (30, 16, 16, 16). BFR was applied at 60% of limb occlusion pressure. Metabolic and cardiac responses were higher for walking lunges (57% V˙O2 max, 66% HRmax) compared with walking (47% V˙O2 max, 61% HRmax). BFR application increased these responses similarly for walking lunges (with BFR: 60% V˙O2 max, 70% HRmax) and walking (with BFR: 53% V˙O2 max, 63% HRmax). These similar responses suggest that bodyweight walking lunges may also be considered aerobic, like walking. Given the similarity of responses between aerobic walking and bodyweight walking lunges, and with BFR significantly enhancing the responses of both modes of exercise compared to their non-BFR equivalents, these findings suggest that practitioners have some flexibility in choice of aerobic BFR exercise modes to implement with individuals where these modes may be more suitable.

期刊介绍: The Journal of Sports Sciences has an international reputation for publishing articles of a high standard and is both Medline and Clarivate Analytics-listed. It publishes research on various aspects of the sports and exercise sciences, including anatomy, biochemistry, biomechanics, performance analysis, physiology, psychology, sports medicine and health, as well as coaching and talent identification, kinanthropometry and other interdisciplinary perspectives. The emphasis of the Journal is on the human sciences, broadly defined and applied to sport and exercise. Besides experimental work in human responses to exercise, the subjects covered will include human responses to technologies such as the design of sports equipment and playing facilities, research in training, selection, performance prediction or modification, and stress reduction or manifestation. Manuscripts considered for publication include those dealing with original investigations of exercise, validation of technological innovations in sport or comprehensive reviews of topics relevant to the scientific study of sport.
