在低强度运动和血流限制 (LI-BFR) 期间,短暂或长时间的休息期间会产生类似的肌肉生长和力量增长. 运动和疼痛等感知反应也显示LI-BFR休息间隔长度之间没有显著差异.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 肌肉生理学 肌肉生理学
背景情况:
- 具有血流限制的低强度运动 (LI-BFR) 可能会增强肌肉力量和肌肉缩.
- 在LI-BFR中增加集间休息间隔可能会增加代谢压力.
- 然而,较长的休息时间也可能会恶化感知反应,如感知到的劳累和疼痛.
研究的目的:
- 为了比较短 (60s) 与长 (120s) 间隔休息间隔对神经肌肉和感知反应对LI-BFR的影响.
- 调查不同休息时间是否会影响LI-BFR训练期间的肌肉适应和主观感受.
主要方法:
- 在13名身体活跃的男性中,采用了随机的受试者内部设计.
- 参与者进行单边LI-BFR (30%-1RM) 倾斜腿压,一只腿在两组之间休息60秒 (G60) 和另一只120秒 (G120).
- 训练包括3组15次重复,每周4次,持续3周,闭塞压力为80%.
- 肌肉横截面积 (CSA) 和1-RM在训练前和训练后被测量;RPE和疼痛在整个过程中被评估.
主要成果:
- G60和G120都显著增加了四肢体CSA和1-RM强度,两组之间没有显著差异.
- 在两组的训练期间,感知劳动力 (RPE) 和疼痛感知率显著下降.
- 对于CSA,1-RM,RPE或疼痛的变化,没有观察到显著的群体间差异.
结论:
- 短时间 (60s) 和长时间 (120s) 的间隔休息间隔都会产生与LI-BFR相比较的肌肉强度和缩适应.
- 对于LI-BFR训练的神经肌肉和感知反应是相似的,无论间隔休息的持续时间如何.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Blood Flow
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
