Stretching is a common component of an athletic warm-up even though many studies have demonstrated that pre-event static stretching can decrease strength and power performance. The purpose of this study was to examine the effects of acute static stretching of the throwing shoulder on pitching velocity and accuracy of National Collegiate Athletic Association Division III baseball players. Twelve collegiate baseball players, including 6 pitchers and 6 position players, participated in the study. Each participant completed 2 separate testing protocols over a span of 4-6 days. In the experimental condition (SS), 6 static stretches were applied to the throwing shoulder after an active warm-up. After a rest period of 5-10 minutes, participants were allowed 5 warm-up pitches from a pitching mound. Participants then threw 10 pitches measured for velocity and accuracy. The control condition (NS) followed the same procedure but did not include the 6 static stretches. Testing was conducted in an indoor practice facility during normal team practice. No significant differences were found in average velocity, maximum velocity, or accuracy measures when comparing the SS and NS conditions. These results suggest that acute static stretching of the throwing shoulder does not have a significant impact on baseball pitching performance. Static stretching of the shoulder may be performed during a warm-up before a throwing activity.
伸展是运动热身的常见组成部分，尽管许多研究表明，赛前静态伸展会降低力量和爆发力表现。本研究的目的是检查投掷肩部急性静态伸展对 NCAA 三级棒球运动员投球速度和准确性的影响。12 名大学生棒球运动员参加了这项研究，其中包括 6 名投手和 6 名位置球员。每个参与者在 4-6 天的时间内完成了 2 个单独的测试方案。在实验条件（SS）下，在主动热身后对投掷肩进行 6 次静态伸展。休息 5-10 分钟后，参与者被允许从投球丘进行 5 次热身投球。然后参与者投掷 10 次测量速度和准确性。对照条件（NS）遵循相同的程序，但不包括 6 次静态伸展。测试在室内练习设施中进行，在正常的团队练习期间进行。在比较 SS 和 NS 条件时，在平均速度、最大速度或准确性测量方面没有发现显著差异。这些结果表明，投掷肩部的急性静态伸展对棒球投球表现没有显著影响。肩部的静态伸展可以在投掷活动前的热身中进行。
