正常年輕成人膝伸肌與屈肌之等速肌力

　　　　　本研究主要目的在於了解正常年輕成人膝伸肌與屈肌之等速肌力。並討 論測試次序，慣用腳，及性別的影響。計有二十八位自願看(女11人，男17人)接 受測試。使用Cybex340，角速度分別在每秒60，180，240度進行。結果發現測試 次序及慣用腳的影響在統計上並無差異。兩男女性別上對肌力上呈現統計上有意 義的差別。但以膝屈肌與伸肌比表示時，則無統計上的差異。同時檢視Cybex340 之信度，其重複測試者及受測者接受不同測試者重複測試的信度範圍介於0.771 與0.938之間。
　　　　　The purpose of this study was to collectthe isokinetic torque of the knee extensors andflexors in normal young adults. Twenty-eightvolunteers (female 11. male 17) were testedwith Cybex 340 at the speed of 60, 180, 240deg/sec, respectively. This study found no effect of test sequence on the peak torque of theknee flexors and extensors and no signiFicantdifference in the peak torque between domunantand nondominant difference (p<0.01). But it did not significantly show the difference between males and females when the relationship of the knee exntensors and flexors wasexpressed as the ratio of hamstrings to quadriceps (H/Q). Interrater reliability was highly correlated on the knee flexors and extensors atthe speed of 60 deg/sec. Intrarater reliabilityhad high correlation on the knee flexors at thespeed of 60 deg/sec and the knee extensors at180 deg/sec. (JPTA ROC 1990; 3:52-57)
