本研究旨在确定作为调节活动(CA)的全量俯卧撑对高负荷卧推性能的影响。两组抗阻训练男性年龄(24.5±2.6岁,体重84.8±8kg)执行了两种CA方案之一:3组5次重复俯卧撑,组间休息间隔1分钟(PAPE;n=12)或相等时间的有氧热身(CONT;n=12)。完成CA方案后4分钟,参与者以70%1RM和两组之间4分钟的休息间隔进行了3组3次重复的卧推运动,以评估峰值功率输出(PP)的激活后差异。平均功率输出(MP),峰值棒材速度(PV),和条件之间的平均条速度(MV)。双向方差分析揭示了PP的显著条件×集合交互效应(p<0.01),MP(p<0.05),PV(p<0.01),和MV(p=0.02)。条件×集相互作用的事后显示,与基线(BA)相比,PAPE导致P-Set2和P-Set3的PP和PV显着降低。与BA和P-Set1相比,PAPE条件的MP和MV在P-Set3期间显著降低。Δ值的t检验比较显示P-Set1-BA在PP中PAPE和CONT之间存在显着差异(p<0.01),在MP中对于P-Set2-P-Set1(p<0.03)和对于P-Set3-P-Set1(p=0.04)。此外,P-Set3-BA;P-Set2-P-Set1;P-Set3-P-Set1的PV存在显着差异(p<0.01;p<0.01;p<0.02)。最后,P-Set1-BA;P-Set2-P-Set1和P-Set3-P-Set1的MV存在显着差异(p<0.01;p<0.01;p<0.02)。这项研究表明,在70%1RM的情况下,俯卧撑可以提高卧推运动的性能。仅在CA之后的第一组中观察到性能的提高,而P-Set2和P-Set3中记录了这些变量的显着减少。
The present study aimed to determine the effects of plyometric push-ups as a conditioning activity (CA) on high-loaded bench press performance. Two groups of resistance-trained males age (24.5 ± 2.6 years, body mass 84.8 ± 8 kg) performed one of two CA protocols: 3 sets of 5 repetitions of plyometric push-ups with a 1 min rest interval between sets (
PAPE; n=12) or equal time aerobic warm-up (CONT; n=12). Four minutes after completion of the CA protocols the participants performed 3 sets of 3 repetitions of the bench press exercise at 70%1RM and 4 min rest interval between sets to assess post-activation differences in peak power output (PP), mean power output (MP), peak bar velocity (PV), and mean bar velocity (MV) between conditions. The two-way ANOVA revealed significant condition × set interaction effect for PP (p<0.01), MP (p<0.05), PV (p<0.01), and MV (p=0.02). The post hoc for condition × set interaction showed that
PAPE caused a significant decrease in PP and PV for P-Set2 and P-Set3 when compared to baseline (BA). The MP and MV for the
PAPE condition decreased significantly during the P-Set3 compared to BA and to P-Set1. The t-test comparisons for delta values showed significant differences between
PAPE and CONT in PP for P-Set1 - BA (p<0.01), in MP for P-Set2 - P-Set1 (p<0.03) and for P-Set3 - P-Set1 (p=0.04). Furthermore, there were significant differences in PV for P-Set3 - BA; P-Set2 - P-Set1; P-Set3 - P-Set1 (p<0.01; p<0.01; p<0.02 respectively). Finally, there were significant differences in MV for P-Set1 - BA; P-Set2 - P-Set1 and P-Set3 - P-Set1 (p<0.01; p<0.01; p<0.02 respectively). This study demonstrated that plyometric push-ups lead to performance enhancement of the bench press exercise at 70%1RM. The increases in performance were observed only in the first set following the CA, while a significant decrease of these variables was registered in P-Set2 and P-Set3.
