中文摘要 | 有關等速向心與等長肌力之研究,過去30年之研究文獻在質與量方面已是十分之完整,但是有關等速離心肌力之探討仍是十分的缺乏與不足﹔本篇研究的目的在於探討甲組網球選手、乙組網球選手與一般健全人其肩旋轉肌群肌力特性,研究之問題主要分析三種族群等速向心、等速離心,及肩外轉肌與內轉肌等速肌力比值,藉此對於網球選手之肩旋轉肌肌力特性與肌力平衡問題有所了解﹔本研究以36名男性受試者參與,每一種組別有12位受試者,使用Kin-Com等速測力機分別測試受試者旋轉肌等速向心及等速離心肌力,使用之角速度60、120及180°/sec,統計T考驗將用於比較慣用邊與非慣用邊之差異,單因子變異數分析用來分析三組在旋轉肌群之差異﹔結果顯示(a)甲組網球選手及乙組網球選手之慣用邊及非慣用邊之內轉肌其向心或離心肌力有顯著差異﹔(b)除了乙組網球選手其慣用邊與非慣用邊外轉肌在60°/sec向心或離心肌力有顯著差異,其餘三組之慣用邊及非慣用邊之外轉肌無顯著差異﹔(c)三種族群中其肩外轉肌與肩內轉肌向心肌力比值並無顯著之差異,但非慣用邊在此平均比值大於1,同時非慣用邊在此比值有大於慣用邊的趨勢﹔經由本篇研究之結果可建議網球選手需注重旋轉肌群肌力比值平衡,藉此以減少因肌力不平衡而產生之運動傷害,建立之數據將可應用於網球訓練、臨床運動醫學及物理治療領域中。 |
英文摘要 | With regard to the research of isokinetic concentric and isometric strength, the quantities and qualities of literature in the previous thirty years were quite sufficient. However, the research on the analysis of isokinetic eccentric strength was still inadequate and far behind. The purpose of this study was to investigate the characteristics of shoulder rotators in elite tennis players, local tennis players, and healthy men. The main analysis focused on the examination of isokinetic concentric strength, isokinetic eccentric strength, and concentric strength ratios of shoulder external and internal rotators in order to identify the balance of strength of shoulder rotators. Thirty-six men (12 elite tennis players, 12 local tennis players and 12 healthy men) participated in this study. A Kin-Com isokinetic dynamometer was used to evaluate concentric and eccentric (angular velocities were 60, 120 and 180 deg/sec) strength of shoulder internal and external rotators. T-tests were used to compare dominant and non-dominant sides in three groups, respectively, and Oneway ANOVA tests were used to compare the differences of strength characteristics among three groups. Results showed that (a) there were significant differences in concentric and eccentric strength of internal rotators between dominant and non-dominant shoulders in three angular velocities at the elite and local tennis players; (b) there were not significant differences in concentric and eccentric strength of external rotators between dominant and non-dominant shoulders at three groups except concentric and eccentric strength of local players at 60 deg/sec; (c) there were not significant differences in concentric strength ratios of shoulder external and internal rotators among three groups, but the ratios in the non-dominant arm were greater than 1. The results of this study suggest that players need to notice the balance of strength of shoulder external and internal rotators in order to prevent or reduce the occurrence of shoulder injuries. In addition, the development of normative data may be applied in tennis training and clinical sports medicine. |
