摘要

本研究的主要目的是评估在卧推运动中,在休息时间施加不同的缺血压力对杠铃速度的影响。10 名接受过阻力训练的男性(年龄 = 23.2 ± 2.7 岁;体重 = 83.9 ± 9 千克;身高 = 181 ± 5.2 厘米;卧推单次最大重量 (1RM) = 125 ± 16.4 千克;训练年限 = 5.4 ± 3.4 年)参加了研究。在随机交叉设计的 4 次实验中,受试者在缺血(50% 或 80% 的动脉闭塞压力)、SHAM 缺血(20 mmHg)和无缺血(对照组)条件下,以 60% 的 1RM 负荷进行了 5 组 3 次卧推练习。在缺血条件下,每组开始前使用袖带 6.5 分钟,并在每组开始前 30 秒释放袖带作为再灌注(6.5 分钟缺血 + 0.5 分钟再灌注)。对照组不进行缺血。双向重复测量方差分析显示,平均杠速度(MV;P = 0.17)和峰值杠速度(PV;P = 0.66)没有明显的条件 × 组交互作用。此外,MV(p = 0.58)和 PV(p = 0.61)也没有条件的主效应。结果表明,缺血或 SHAM 处理(6.5 分钟缺血或 SHAM + 30 秒再灌注)不会影响卧推运动中的平均杆速和峰值杆速,与施加的压力无关。

Effects of different ischemic pressures on bar velocity during the bench press exercise: A randomized crossover trial.

The main objective of this study was to evaluate the effects of different ischemic pressures applied during rest intervals on bar velocity during the bench press exercise. 10 resistance-trained males (age = 23.2 ± 2.7 years; body mass = 83.9 ± 9 kg; body height = 181 ± 5.2 cm; bench press 1 repetition maximum (1RM) = 125 ± 16.4 kg; training experience = 5.4 ± 3.4 years) participated in the study. During 4 experimental sessions, following a randomized crossover design, the subjects performed 5 sets of 3 repetitions of the bench press exercise with a load of 60% 1RM under conditions: with ischemia (50% or 80% of arterial occlusion pressure), with SHAM ischemia (20 mmHg) and without ischemia (control condition). For the ischemic conditions cuffs were applied before each set for 6.5 min and released 30 s before the start of the set as reperfusion (6.5 min ischemia + 0.5 min reperfusion). In the control condition, ischemia was not applied. The two-way repeated measures ANOVA showed no significant condition × set interaction for mean bar velocity (MV; p = 0.17) and peak bar velocity (PV; p = 0.66). There was also no main effect of condition for MV (p = 0.58) and PV (p = 0.61). The results indicate that ischemic or SHAM treatment (6.5 minutes ischemia or SHAM + 30 s reperfusion) does not affect mean and peak bar velocity during the bench press exercise regardless of the applied pressure.
