目的:探究静力性拉伸(SS)和专项化动力性拉伸(DS)对高水平女运动员(19.9±1.6岁,1.80±0.06 m、76.87±9.95 kg)动力学指标(峰值力、起跳时间、发力速度)的影响。方法:收集3天的数据(随机选取研究对象,并安排对照训练)。在每一个拉伸组(SS组vs.DS组vs.对照组)的持续时间相同(总时间7 min;每一肌群进行30 s)。拉伸后1 min和15 min,受试者在测力台上进行下蹲式纵跳测试。与静力拉伸后1 min相比,动力拉伸组发力速度、峰值力以及腾空时间等动力学参数明显提高,但在15 min时没有发现显著作用。结论:当训练和比赛要求最快的跳跃,女运动员应结合动力性拉伸而不是静力拉伸作为赛前热身的一部分,但热身应在15 min之内进行以获得最大收益。
Objective: To investigate the effects of static stretch (SS) and special dynamic stretch (DS) on the dynamics of high-level female athletes (19.9 ± 1.6 years, 1.80 ± 0.06 m, 76.87 ± 9.95 kg) Time, force speed) impact. METHODS: Three days of data were collected (subjects were randomly selected and control training was arranged). The duration of each stretching group (SS vs. vs. DS vs. control) was the same for a total duration of 7 min; 30 s for each muscle group. At 1 min and 15 min after stretching, the subjects performed a squat test on the dynamometer. Compared with 1 min after static stretching, the kinetic parameters such as force-generating speed, peak force and emptying time of dynamic stretching group were significantly increased, but no significant effect was found at 15 min. Conclusion: When training and competition require the fastest jumps, the female athlete should incorporate dynamic stretch instead of static stretch as part of pre-match warm-up, but warm-up should take place within 15 minutes for maximum benefit.
