發展健康運動員核心神經肌肉控制能力之評估系統

研究背景：核心穩定能力已被證實與下肢傷害及下背痛存在關聯性，許多測試方法也因應而生，但目前的測試方法多偏向評估核心穩定能力的肌耐力，但對於運動員來說，肌力、爆發力及神經肌肉控制能力則是核心穩定中更重要的環節，因此針對運動員應該有一套適用的測試系統。研究目的：本研究欲發展一套針對運動員核心能力表現的測試方法，了解此測試方法的信度及是否能藉由壓力重心移動之軌跡及區域來分辨受試者之間能力的差異。研究方法： 本研究中徵召20名20歲以上的現役大學運動員，必須接受過五年以上正規的訓練，並以肌電圖儀器及力板收取受試者在執行動作測試時的數據。結果與討論：研究結果顯示右手左腳抬起的鳥狗式之重心壓力移動區域與左側腹橫肌會呈現正向相關性(R=0.583, p=0.009)，右手左腳抬起的鳥狗式之重心壓力移動軌跡跟左側腹橫肌會呈現正向相關性(R=0.535, p=0.018)，而單因子變數分析則顯示七個核心測試動作的重心壓力移動區域及移動軌跡之間存在顯著差異性。 結論：只有右手左腳抬起的鳥狗式在執行時左側腹橫肌會與重心壓力移動區域及移動軌跡產生相關性，但從受試者七個動作的重心壓力移動軌跡及移動區域之表現中可看出核心穩定能力的差異。

Background: The connection between core stability and lower extremity injury and lower back pain has been reported.Currently, most assessment methods are used to test muscle endurance and core stability.However,because the activities of athletes tend to exhibit dynamic patterns, muscle strength, muscle power, and neuromuscular control are highly vital components of core stability; therefore, an assessment system that considers multiple components should be established for athletes. Purpose: The aim of this study was to develop acore stability assessment technique for athletes and prove its reliability and applicability in discriminating the core stability conditions among different subjects. Method: This study recruited 20 student athletes who had undergone formal training for more than 5 years.An electromyographic and force platform were used to record data whilethe athletes executed thesecore stability exercise, and their center of pressure (COP) were assessed. Result: Analysis results showed that when the athletes performed the Bird Dog exercise with the right hand and left leg raised, both the COP path length and COP path area demonstrated a positive moderate correlation. Conclusion: Only theBird Dog exercise with the right hand raisedinvolves a correlation between the COP and electromyographic signals, but the difference in core stability among the athletes can be determined because of the significant difference existon core stability movementswas found.
