本研究在探討棒球運動員使用動態伸展合併肌內效貼紮（肌貼）對平衡、衝刺表現與敏捷性之急性影響。30位健康男性成年的乙組棒球運動員自願參與研究，研究實驗為前測—後測控制組設計。實驗開始前，受試者隨機且平均分配至肌貼組或控制組（假貼組）。每位受試者在體適能指導員指導下進行動態伸展。動態伸展內容為直線20公尺距離內，伸展左、右腳各14次，共3組，組間休息1分鐘；伸展肌群為大腿前側、後側、內側，以及小腿後側，並於動態伸展前、動態伸展後進行Y字平衡、20公尺衝刺、5-10-5敏捷性測驗。本研究結果顯示，在三種測試上，組別與測驗時間因子的交互作用皆未達顯著水準。肌貼組和控制組的Y型平衡測驗總分在動態伸展後的表現顯著優於動態伸展前，但兩組之間未達顯著差異。然而，20公尺衝刺及5-10-5公尺敏捷性測驗的測試上，組別與測驗時間因子的主要效果未達顯著差異。本研究結論是肌貼加上動態伸展無法提供加乘效益來改善健康棒球運動員之運動表現。然而，動態伸展可能有助於提升下肢動態平衡的表現。

This study aimed to investigate the acute effect of dynamic stretching (DS) with Kinesio taping (KT) on sprint, agility and balance in baseball athletes. Thirty healthy amateur baseball players were participated in the experiment. This study was a pretest-posttest control group design. Participants were matched and randomly assigned into KT group or control group (sham taping). A fitness trainer instructed the participants to perform DS sequentially. Three sets of stretching per muscle group were performed (14 times for each muscle of both legs) with a 1-minute recovery between sets over a distance of 20 m. Stretching muscles included anterior, posterior and medial thighs as well as calves. All subjects performed Y balance, 20-m sprint and 5-10-5 agility tests before and after the DS instruction. The results showed that there was no significant interaction effect between the groups and time in three tests. Both groups after receiving DS had significantly greater performance on Y balance test compared with baseline. Nevertheless, no significant difference on Y balance test was observed between the KT and control groups. Furthermore, no significant group and time main effects were noticed on 20-m sprint and 5-10- 5 agility tests. In conclusion, this study suggests that KT incorporated with DS cannot provide a synergistic effect on exercise performance of healthy baseball players. However, performing DS may improve the dynamic balance in the lower limb.
