不同熱身方式於慢性踝關節不穩定之成年人在運動表現之急性效益
Acute effects of different warm-ups on exercise performance in adults with chronic ankle instability
摘要
研究背景: 在運動場上腳踝扭傷是非常常見的運動傷害，而重覆性的扭傷可能就會導致慢性踝關節不穩定(chronic ankle instability, CAI)。熱身是減少運動傷害及促進運動表現的重要因子。目前震動滾筒應用於腳踝的研究不算太多，而針對於CAI的研究更是幾乎沒有。因此，本研究探討比較熱身時執行震動滾筒、非震動滾筒、靜態伸展於慢性踝關節不穩定成年人在運動表現之立即效益。 目的: 探討震動滾筒的介入相較於一般滾筒以及靜態伸展，對於成年人慢性踝關節不穩定在運動表現的立即影響。 方法: 本研究採取交叉試驗。16位符合CAI的受試者皆隨機完成3種不同的介入方式，分別是震動滾筒(vibration rolling, VR)、一般泡棉滾筒(foam rolling, FR)、靜態伸展(static stretching, SS)。實驗流程為前測(踝關節活動度、本體感覺、等速最大肌力、下肢動態平衡)，接著抽籤不同方式的熱身介入於小腿前測及後測(單腳6組30秒於小腿前漢後肌群，震動頻率為28Hz，滾動頻率為40下/分鐘)，而介入結束後進入後測。 結果: 與前測相比，VR能提升小腿背屈(提升33.34%,p = 0.008)、蹠曲(提升6.6%, p = 0.014)、內翻(提升12.06%, p = 0.008)、外翻活動度(提升37.21%, p = 0.034)、外翻120⁰/s(提升31.74%, p = 0.011)及內翻30⁰/s(提升30.46%, p = 0.027)的肌力，FR提升小腿背屈(提升23.68%, p = 0.029)、蹠曲活動度(提升4.59%, p = 0.029)及動態平衡能力(提升1.63%, p = 0.023)，SS提升蹠屈活動度(提升4.39%, p = 0.02)、外翻30⁰/s的肌力(提升8.43%, p = 0.012)；三組間比較，VR在背屈活動度以及外翻120⁰/s的最大肌力顯著地比SS好(背屈: p = 0.007; 外翻: p = 0.038)。 結論: 震動滾筒於小腿前後側肌群的介入是相當適合患有慢性踝關節不穩定的運動員於熱身時操作，不僅可以增加踝關節背屈的角度以及肌力，也不會使其失去本體感覺以及平衡能力。

Background: Ankle sprains is a common injury on the flied, and repeated ankle sprains may cause chronic ankle instability (CAI). Warm-up is an important factor in reducing sports injuries and enhancing sports performance. Therefore, this study explores the immediate benefits of performing vibrating rollers (VR), foam rollers (FR), and static stretching (SS) during warm-ups in adults with chronic ankle instability in sports performance. Aim: To explore the acute effect of the intervention of the vibrating roller on the sports performance of adults with chronic ankle instability compared with the foam rollers and static stretching. Method: This study was a crossover study. Sixteen adults with CAI were randomized to perform VR, FR, and SS as warm-up. These three interventions were performed by all participants in random order separated by 48 hours. The study procedure was: pre-test (ankle range of motion, proprioception test, muscle max strength test, lower-limb dynamic balance), intervention (30s*6sets*dorsiflexors and plantarflexors, vibrate frequency=28Hz, rolling frequency=40 times/minutes) and then did the post-test right after intervention. Result: Time effect: VR significantly improved ankle dorsiflexion (33.34%,p= 0.008), plantarflexion (6.6%, p= 0.014), inversion (12.06%, p= 0.008), eversion (37.21%, p= 0.034), eversion 120⁰/s max strength (31.74%, p= 0.011), inversion 30⁰/s max strength (30.46%, p= 0.027); FR improved ankle dorsiflexion (23.68%, p= 0.029), plantarflexion (4.59%, p= 0.029), dynamic balance (1.63%, p= 0.023); SS improved ankle plantarflexion (4.39%, p= 0.02), eversion 30⁰/s max strength (8.43%, p= 0.012). Group effect: VR significantly improved ankle dorsiflexion and eversion 120⁰/s max strength compared with SS. (dorsiflexion: p= 0.007; eversion 120⁰/s max strength: p= 0.038). Conclusion: The intervention of the vibrating roller on the anterior and posterior muscles is recommended for athletes with chronic ankle instability during warm-up. It can not only increase the ankle dorsiflexion range of motion and muscle strength, but also will not lose proprioception and balance ability
