【摘要】：目的:本研究旨在通过比较不同负荷的末端释放训练对下肢纵跳成绩的影响,来寻找末端释放训练诱导下肢纵跳的后激活效应的最佳负荷和间歇时间,从而为训练和比赛的热身活动提供参考和建议。方法:选取9名北京体育大学男性跳远项目的学生为受试对象,随机进行以下3种负荷的蹲跳训练干预:30%1RM或60%RM固定轨迹的无负重离心阶段的末端释放训练;30%1RM的固定轨迹的传统末端释放训练。随机休息2min、4min、8min后测试CMJ的峰值功率(w/kg)。将CMJ的峰值功率做重复测量方差分析,比较不同负荷和间歇时间后CMJ的峰值功率。结果:研究一结果显示两种形式的下蹲跳干预训练对CMJ峰值功率不存在显著的影响(P0.05),间歇时间对最大峰值功率改变量存在显著的影响(P0.05);无负重离心阶段的末端释放训练干预后2min、4min、8min时CMJ峰值功率显著性差异分别为0.016、0.006、0.355;传统末端释放训练干预后2min、4min、8min时CMJ峰值功率显著性差异分别0.073,0.002,0426;研究二结果显示无负重离心阶段的末端释放训练干预后,间歇时间对CMJ峰值功率存在极显著的影响(P0.01);训练负荷对CMJ峰值功率存在显著的影响(P0.05);间歇时间和训练负荷之间存在交互作用(P0.05),无负荷训练干预后2min、4min、8min时的CMJ峰值功率都无显著性差异(P0.05),分别为0.816、0.746、0.265;30%1RM训练干预后2min、4min、8min时CMJ峰值功率显著性差异分别0.025,0.000,0.067,;60%1RM训练干预后2min、4min、8min时CMJ峰值功率显著性差异分别0.003、0.899、0.001。结论:1.两种形式的下蹲跳末端释放训练后,在一定时间内都能对CMJ的成绩产生后激活效应,且二者使CMJ峰值功率出现显著性差异的间歇时间都是4min;2.无负重离心阶段的末端释放训练干预,CMJ峰值功率出现显著性提高的方案为30%1RM训练干预后4min、60%1RM训练干预后8min。
[Abstract]:Objective: the aim of this study was to find out the optimal load and interval time for the post-activation effect of end-release training on lower limb longitudinal jump by comparing the effects of end-release training on lower limb longitudinal jump performance. Thus provides the reference and the suggestion for the training and the match warm-up activity. Methods: nine male long jump students from Beijing physical Education University were selected as subjects. The following three kinds of squatting and jumping training were carried out randomly: 301RM or 60%RM fixed track end release training in the centrifuge stage without load and 301RM fixed track traditional end release training. The peak power of CMJ was measured at 2 min, 4 min and 8 min. The peak power of CMJ was measured repeatedly by variance analysis, and the peak power of CMJ was compared after different load and intermittent time. Results: the results of study 1 showed that there was no significant effect on peak power of CMJ by two forms of squatting and jumping intervention training, while intermittent time had a significant effect on the change of maximum peak power. The significant difference of peak power of CMJ at 2 min, 4 min and 8 min after radiation training was 0.016 ~ 0.006 ~ 0.355, respectively, and the difference of peak power of CMJ was significant at 2 min ~ 4 min ~ 8 min after conventional terminal release training, respectively. The results showed that the peak power of CMJ was 0.073 卤0.002 ~ 0426 in centrifugation stage, respectively. The effect of intermittent time on CMJ peak power was extremely significant (P0.01), training load had significant effect on CMJ peak power (P0.05), there was interaction between intermittent time and training load (P0.05), and the peak work of CMJ at 2 mins and 4 min ~ 8min after no load training intervention. There was no significant difference in the rate of CMJ between 0. 05% and 0. 05% (P 0. 05), which were 0. 816 ~ 0. 746- 0. 265m, respectively. The peak power of CMJ was 0. 025 ~ 0. 000 and 0. 067 ~ 601RM at 2 min and 0. 8min respectively. There was a significant difference in peak power of CMJ at 2 mins, 0. 8min and 0. 899t. 001, respectively. Conclusion 1. After two kinds of squat jump end release training, both of them can produce post-activation effect on CMJ scores in a certain time, and the interval between them to make the peak power of CMJ appear significant difference is 4 mins / 2. In the end release training without load, the peak power of CMJ increased significantly after 30%1RM training at 4 min, 601 min, 8 min after the intervention of RM training.
