■这项研究检查了带有血流限制(BFR)的8周复杂训练(CT)对功率输出和棒速度的影响。
■26名健康的男性大学运动员(年龄:19.40±0.88岁)用BFR(CT_BFRT,n=13)或仅CT(即,对照)(n=13)每周(即,共24个会议)。在干预之前和之后,参与者完成了一次重复最大(1RM)深蹲评估的功率测量,深蹲跳跃(SJ),反运动跳跃(CMJ),和平均功率(MP),峰值功率(PP),平均棒材速度(Bar-MV),和半蹲跳跃期间的峰值杆速度(Bar-PV)。
■双向方差分析模型显示出时间的显着主要影响(p<0.001),而不是组(p>0.89)或组与时间之间的相互作用(p>0.37)。蹲,SJ,或CMJ;然而,在MP中观察到显著的相互作用(p=0.03,科恩的d=1.39),PP(p=0.03,科恩的d=1.14),Bar-MV(p=0.049,科恩的d=1.26),和Bar-PV(p=0.01,科恩的d=1.56)。事后分析显示,国会议员,PP,Bar-MV,与所有其他三种情况相比,使用BFRT进行CT后的Bar-PV明显更大(即,pre-CT_BFRT,仅在CT前后)。
■具有BFR的CT可能会在半深蹲跳跃过程中引起功率输出和杆速度的显着更大的改善,并在深蹲的1RM中引起可比的改善,SJ,和男性的CMJ相比,只有CT,这表明这种新型CT与BFR将是一个有希望的策略,以提高健康的男性大学运动员的力量表现。
UNASSIGNED: This
study examined the effects of 8-week complex training (CT) with blood flow restriction (BFR) on
power output and bar velocity.
UNASSIGNED: Twenty-six healthy male university athletes (age: 19.40 ± 0.88 years) completed three sessions of CT with BFR (CT_BFRT, n = 13) or CT-only (i.e., control) (n = 13) per week (i.e., 24 sessions in total). Before and immediately after intervention, participants completed power measurement as assessed by one-repetition maximum (1RM) squat, squat jump (SJ), countermovement jump (CMJ), and mean
power (MP), peak
power (PP), mean bar velocity (Bar-MV), and peak bar velocity (Bar-PV) during the half-squat jump.
UNASSIGNED: Two-way ANOVA models showed significant main effect of time (p < 0.001) but not group (p > 0.89) or interaction (p > 0.37) between group and time on 1RM of the squat, SJ, or CMJ; however, significant interactions were observed in MP (p = 0.03, Cohen\'s d = 1.39), PP (p = 0.03, Cohen\'s d = 1.14), Bar-MV (p = 0.049, Cohen\'s d = 1.26), and Bar-PV (p = 0.01, Cohen\'s d = 1.56). The post hoc analyses revealed that MP, PP, Bar-MV, and Bar-PV after CT with BFRT were significantly greater compared to all the other three conditions (i.e., pre-CT_BFRT, pre- and post-CT-only).
UNASSIGNED: CT with BFR may induce significantly greater improvements in
power output and bar velocity during half-squat jump and induce comparable improvements in 1RM of the squat, SJ, and CMJ of males as compared to CT only, suggesting this novel CT with BFR would be a promising strategy to enhance
power performance in healthy male university athletes.
