男子排球選手下肢肌力、腿後肌與股四頭肌力比值和跳躍表現之相關性

本研究目的在探討大專男子排球選手下肢肌力、腿後肌與股四頭肌力比值（hamstrings to quadriceps strength ratio, H/Q ratio）與不同跳躍表現之相關性。以14名大專男子排球選手在大專排球聯賽決賽前7天完成不同跳躍（下蹲跳、蹲踞跳、落地跳）測試與腿後肌群、股四頭的等速（60, 180, 300°/s）向心、離心收縮力矩峰值測試，所測得的肌力比值進一步計算傳統式H/Q比值與功能性H/Q比值。研究結果發現：功能性H/Q比值與男子排球運動員的下蹲跳有顯著負相關，腿後肌群在180角速度之下的向心肌力也與蹲踞跳高度達顯著負相關。本研究結論為：功能性H/Q比值相較於傳統式H/Q比值更能預測下蹲跳之表現，未來體能訓練師可透過腿後肌群的離心肌力與股四頭肌群的向心肌力比值作為肌力訓練編排之參考。

The purpose of this study was to investigate the relationships among muscle strength of lower extremities, hamstrings to quadriceps strength ratio (H/Q ratio), and jumping performances in collegiate men's volleyball players. Seven days prior to the University Volleyball League finals, 14 collegiate men's volleyball players performed countermovement jumps (CMJ), squat jumps (SJ), drop jumps (DJ) tests, and isokinetic concentric and eccentric contraction peak torque (PT) of their dominant quadriceps and hamstrings. The PT was measured at 60°/s, 180°/s, and 300°/s using an isokinetic dynamometer. Conventional H/Q ratio was calculated as the concentric hamstring to concentric quadriceps peak torque, and the functional H/Q ratios were calculated as the eccentric quadriceps to concentric hamstring peak torque. The results showed that there was a significantly negative relationship between functional H/Q ratio and countermovement jump performance in men's volleyball players. The hamstrings concentric PT at 180°/s also showed a significantly negative relationship with SJ. Based on the results, we conclude that the functional H/Q ratio is more effective than the conventional H/Q ratio in predicting the countermovement jump performance. H/Q ratio could have applications in strength and conditioning coach to modify the program of strength training.
