Abstract
Post-activation potentiation enhancement (PAPE) refers to increased force generation following a muscular conditioning pre-activity that acutely enhances subsequent strength and power performance. Athlete apprehension to use heavy weights (i.e. >80%1RM) immediately before a competition or inability to use weights before the performance (e.g. due to regulations) prevent materialising the benefits of PAPE. Therefore, this study examined whether PAPE can be induced with bodyweight squats. Sixteen healthy, team sports players (male: 10, female: 6, mean ± SD: age 22.2 ± 3.0 years, height 1.67 ± 0.08 m, body mass 70.2 ± 8.2 kg) performed three sets of ten repetitions of bodyweight squats with 30 seconds recovery between each set. A countermovement jump was performed 5 minutes before, 2 and 4 minutes after the squat sets and jump height was calculated. The results showed existence of PAPE with the jump height increasing at both 2 (30.8 ± 5.6 cm, p = 0.045, g = 0.21) and 4 (30.8 ± 6.1 cm, p = 0.037, g = 0.20) minutes, compared to baseline (29.5 ± 6.4 cm). This is the first study to use bodyweight squats rather than loaded squats. Our findings indicate that three sets of ten repetitions of squats using bodyweight only can be a sufficient stimulus to induce PAPE.
激活后增强(PAPE)是指在肌肉调节前活动后产生的力量增加,从而显著增强随后的力量和动力表现。运动员在比赛前立即使用重物(即大于80%1RM)或在表演前无法使用重物(例如由于规定)会阻碍PAPE的效益实现。因此,本研究考察了体重深蹲是否可以诱发PAPE。16名健康的团体运动员(男10人,女6人,平均±标准差:年龄22.2±3.0岁,身高1.67±0.08 m,体重70.2±8.2 kg)进行3组体重深蹲,每组重复10次,每组之间恢复30秒。在深蹲练习前5分钟、后2分钟和后4分钟分别做一个反动作跳跃,并计算跳跃高度。结果显示,与基线(29.5±6.4 cm)相比,跳跃高度分别在2(30.8±5.6 cm, p = 0.045, g = 0.21)和4(30.8±6.1 cm, p = 0.037, g = 0.20) min时增加,存在PAPE。这是第一个使用体重深蹲而不是负重深蹲的研究。我们的研究结果表明,三组10次重复的深蹲只使用体重可以是一个足够的刺激,以诱导PAPE。
