The aim of the present trial was to investigate the effect of two stretching programs, a dynamic and a static one, on the sprint ability of recreational volleyball players. The sample consisted of 27 male recreational volleyball players (age 21.6 ± 2.1 years, mean ± standard deviation, body mass 80.3 ± 8.9 kg, height 1.82 ± 0.06 m, body mass index 24.3 ± 2.5 kg.m, volleyball experience 7.7 ± 2.9 years). Participants were randomly divided into three groups: (a) the first performing dynamic stretching exercises three times per week, (b) the second following a static stretching protocol on the same frequency, and (c) the third being the control group, abstaining from any stretching protocol. The duration of the stretching exercise intervention period was 6 weeks, with all groups performing baseline and final field sprinting tests at 4.5 and 9 m. The post-test sprint times were faster in both the 4.5 ( = 0.027, η = 0.188) and 9 m tests ( < 0.001, η = 0.605) compared to the pre-test values. A large time × group interaction was shown in both the 4.5 ( = 0.007, η = 0.341) and 9 m tests ( = 0.004, η = 0.363) with the static and dynamic stretching groups being faster in the post-test than in the pre-test, whereas no change was found in the control group. The percentage change in the 4.5 m sprint time correlated with volleyball experience ( = -0.38, = 0.050), i.e., the longer the volleyball experience, the larger the improvement in the 4.5 m sprint. Thus, it is concluded that both stretching techniques have a positive effect on the velocity of recreational male volleyball players, when performed at a frequency of three times per week for 6 weeks under the same conditions as defined in the study protocol.
本试验旨在研究两种拉伸方案（动态和静态）对娱乐性排球运动员短跑能力的影响。样本由 27 名男性娱乐性排球运动员组成（年龄 21.6 ± 2.1 岁，均值 ± 标准差，体重 80.3 ± 8.9kg，身高 1.82 ± 0.06m，体重指数 24.3 ± 2.5kg·m，排球经验 7.7 ± 2.9 年）。参与者被随机分为三组：（a）第一组每周进行三次动态拉伸练习，（b）第二组按照相同的频率进行静态拉伸方案，（c）第三组为对照组，不进行任何拉伸方案。拉伸运动干预期持续 6 周，所有组均在 4.5m 和 9m 处进行基线和最终的场域冲刺测试。与预测试值相比，后测试的 4.5m（ = 0.027，η = 0.188）和 9m 测试（ < 0.001，η = 0.605）的冲刺时间都更快。4.5m（ = 0.007，η = 0.341）和 9m 测试（ = 0.004，η = 0.363）中均显示出较大的时间×组交互作用，静态和动态拉伸组在后测试中比在前测试中更快，而对照组则没有变化。4.5m 冲刺时间的百分比变化与排球经验相关（ = -0.38， = 0.050），即排球经验越长，4.5m 冲刺的提高幅度越大。因此，当在相同条件下每周进行三次、持续 6 周时，两种拉伸技术对娱乐性男性排球运动员的速度均有积极影响。
