The aim of this study was to determine the influence of different percentages of blood flow restriction (BFR) and loads on mean propulsive velocity (MPV) and subjective perceived exertion during squat (SQ) and bench press (BP) exercises.
Higher percentages of BFR will positively affect dependent variables, increasing MPV and reducing perceived exertion.
Cross-sectional study.
Level 3.
Eight healthy young male athletes took part. Two sets of 6 repetitions at 70% 1-repetition maximum (1RM), 2 sets of 4 repetitions at 80% 1RM, and 2 sets of 2 repetitions at 90% 1RM were performed randomly; 5-minute recoveries were applied in all sets. The varying arterial occlusion pressure (AOP) applied randomly was 0% (Control [CON]), 80%, and 100%.
No statistically significant differences in MPV were found during the BP exercise at any percentage of BFR at any percentage 1RM. During the SQ exercise, MPV results showed statistically significant increases of 5.46% ( = 0.04; = 0.31) between CON and 100% AOP at 90% 1RM. The perceived exertion results for the BP exercise showed statistically significant reductions of -8.66% ( < 0.01; = 0.06) between CON and 100% AOP at 90% 1RM. During the SQ exercise, the perceived exertion results showed significant reductions of -10.04% ( = 0.04; = 0.40) between CON and 100% AOP at 80% 1RM; -5.47% ( = 0.02; = 0.48) between CON and 80% AOP at 90% 1RM; and -11.83% ( < 0.01; = 0.66) between CON and 100% AOP at 90% 1RM.
BFR percentages ~100% AOP at 90% 1RM improved acutely MPV (only in SQ exercises) and reduced acutely perceived exertion (in both exercises). These findings are important to consider when prescribing resistance training for healthy male athletes.
本研究的目的是确定不同百分比的血流限制（BFR）和负荷对深蹲（SQ）和卧推（BP）运动中平均推进速度（MPV）和主观疲劳感知的影响。
较高百分比的BFR将对因变量产生积极影响，增加MPV并降低疲劳感知。
横断面研究。
3级。
八名健康的年轻男性运动员参与。随机进行两组6次重复，负荷为1次重复最大值（1RM）的70%；两组4次重复，负荷为1RM的80%；两组2次重复，负荷为1RM的90%；所有组间均有5分钟的恢复时间。随机施加的不同动脉闭塞压力（AOP）分别为0%（对照组[CON]）、80%和100%。
在BP运动中，任何百分比1RM下的任何BFR百分比，MPV均未发现统计学上的显著差异。在SQ运动中，在90% 1RM时，CON与100% AOP之间的MPV结果显示出统计学上显著增加了5.46%（P = 0.04；Cohen's d = 0.31）。BP运动的疲劳感知结果显示，在90% 1RM时，CON与100% AOP之间有统计学上显著降低了-8.66%（P < 0.01；Cohen's d = 0.06）。在SQ运动中，疲劳感知结果显示，在80% 1RM时，CON与100% AOP之间显著降低了-10.04%（P = 0.04；Cohen's d = 0.40）；在90% 1RM时，CON与80% AOP之间降低了-5.47%（P = 0.02；Cohen's d = 0.48）；在90% 1RM时，CON与100% AOP之间降低了-11.83%（P < 0.01；Cohen's d = 0.66）。
在90% 1RM时，BFR百分比为~100% AOP可急性改善MPV（仅在SQ运动中）并急性降低疲劳感知（在两项运动中）。在为健康男性运动员制定抗阻训练计划时，这些发现具有重要的参考价值。
