It is also called the jumper’s knee. Infrapatellar strap is a knee brace usually used for patellar tendinopathy. There were very little literatures regarding the effect of infrapatellar strap on athletic performance. Therefore, the purpose of this study was to investigate the effect of infrapatellar strap on quadriceps strength and jumping biomechanics. Methods: Fourteen healthy subjects participated in this study. Biodex isokinetic dynamometer and surface electromyography system were used to measure the quadriceps strength and muscle activation in isokinetic testing. A force plate was used to measure the ground reaction force, loading rate and flying time in counter movement jump, squat jump and drop jump. Paired t test was used to compare the differences between no strap and infrapatellar strap. Results: No significant difference was found on quadriceps strength and muscle activation in isokinetic testings with the angular velocity of 30 – 180 °/s. The use of infrapatellar strap significantly increased the vertical ground reaction force during taking off of squat jump. There was an increasing trend on the vertical ground reaction force of landing after the use of infrapatellar strap. Conclusion: This study suggested that the quadriceps strength and muscle activation would not be affected by infrapatellar strap. The jumping movements involved in stretch-shortening cycle would not be affected by infrapatellar strap. Infrapatellar strap would increase the push up force in squat jump.中文摘要.................................I Abstract.................................II 謝誌.....................................III 目錄.....................................IV 表目錄...................................VI 圖目錄...................................VII 第壹章 緒論............................1 第一節 研究背景........................1 第二節 研究動機........................4 第三節 研究目的........................6 第貳章 文獻回顧........................8 第一節 髕腱炎的簡介....................8 第二節 髕腱炎的發生率..................10 第三節 髕腱炎的機轉....................13 第四節 髕腱炎的影響因子................19 第五節 本章結語........................26 第叁章 研究方法與步驟..................28 第一節 研究對象........................28 第二節 實驗時間及地點..................29 第三節 實驗儀器與設備..................30 第四節 研究設計........................37 第五節 資料分析........................46 第六節 統計分析........................48 第肆章 結果............................49 第一節 研究參與者基本資料..............49 第二節 股四頭肌肌力的比較..............50 第三節 肌肉活化程度的比較..............52 第四節 不同跳躍模式之生物力學參數......58 第伍章 討論............................67 第一節 護具對肌力的影響................68 第二節 護具對肌肉活化程度的影響........70 第三節 護具對跳躍生物力學的影響........72 第四節 研究限制........................76 第陸章 結論與建議......................77 參考文獻................................791593546 bytesapplication/pdf膝護具;膝伸肌肌力;肌肉活化程度;垂直地面反作用力knee brace;knee extensor strength;muscle activation;vertical ground reaction forcethesis
