目的:探讨恢复时间和力量素质对后激活增强效应(postactivation potentiation,简称PAP)效果的影响。方法:受试者为23名体育大学体能班男生,根据受试者1 RM/体重数值分组,1 RM/体重〉2为L组,≤2为S组。使用90%1 RM重复5次间歇1 min为PAP诱导强度,PAP诱导前以及诱导后每4 min采集受试者下蹲跳(CMJ)相关指标:高度、峰值功率、峰值冲量、峰值力量变化率(RFD)。使用重复测量单因素方差分析的方法分析恢复时间是否对各指标存在影响。使用多元方差分析比较下肢力量对各指标的影响。显著性定义为一类误差概率小于0.05。结果:恢复时间对PAP效果存在显著影响,体现在峰值功率上(P〈0.05),诱导后4 min和8 min时峰值功率显著高于基础值(P〈0.008),其他指标均无显著变化(P〉0.05)。L组与S组间无显著差异。结论:90%1 RM重复5次间歇1 min的负重半蹲后4 min和8 min时爆发力有所提高。下肢相对力量对PAP效果并没有影响。PAP对下肢爆发力的增强效果存在较大的个体差异。
目的:探討恢複時間和力量素質對後激活增彊效應(postactivation potentiation,簡稱PAP)效果的影響。方法:受試者為23名體育大學體能班男生,根據受試者1 RM/體重數值分組,1 RM/體重〉2為L組,≤2為S組。使用90%1 RM重複5次間歇1 min為PAP誘導彊度,PAP誘導前以及誘導後每4 min採集受試者下蹲跳(CMJ)相關指標:高度、峰值功率、峰值遲量、峰值力量變化率(RFD)。使用重複測量單因素方差分析的方法分析恢複時間是否對各指標存在影響。使用多元方差分析比較下肢力量對各指標的影響。顯著性定義為一類誤差概率小于0.05。結果:恢複時間對PAP效果存在顯著影響,體現在峰值功率上(P〈0.05),誘導後4 min和8 min時峰值功率顯著高于基礎值(P〈0.008),其他指標均無顯著變化(P〉0.05)。L組與S組間無顯著差異。結論:90%1 RM重複5次間歇1 min的負重半蹲後4 min和8 min時爆髮力有所提高。下肢相對力量對PAP效果併沒有影響。PAP對下肢爆髮力的增彊效果存在較大的箇體差異。

Purpose:The aim of this study was to determine the effect of recovery time and strength quality on postaetivation potentiation (PAP). Methods :Twenty three male college students were recruited and divided into L group ( 1 RM / body weight 〉 2) and S group ( 1 RM/body weight ≤ 2). PAP was induced by half back-squat of five repetitions at 90% 1 RM with 1 min interval. Jumping height, peak power, peak impulse, and peak strengthen were measured every 4 min before and after PAP. The effect of recovery time on these parameters was analyzed by repeated-measures ANOVA, and the effect of lower extremity strength on these parameters was analyzed by multiva- riate analysis of variance. Results : The effect of recovery time on PAP is significant. But only peak power at 4 min and 8 min after PAP was higher than that at baseline (Ps 〈 0.01 ) , other parameters didn't change (Ps 〉 0. 05 ) . There was no difference between L and S groups. Conclusions : Explosive force is improved at 4 rain and 8 min af- ter half back-squat of five repetitions at 90% 1 RM with 1 min interval. Lower extremity strength doesn't affect PAP. The improvement of explosive force of lower extremity has individual difference.
