The purpose of this study was to investigate the torque-angle relationship of the knee flexor and extensor in healthy adults. Eighty-one subjects were participated in this study(men: forty, women: forty-one). The participants performed maximal voluntary isometric contractions at five knee joint angle(90, 70, 50, 30, 10). As for statistical verification, repeated measures ANOVA was conducted, and in case that there were significant differences in torque according to the changes in knee angle, contrast test for the rest of the knee angles based on peak angle was performed.
The maximal torque was greater in the men group than women group in all the knee angles(flexor, extensor). Torque-angle relationship curve was revealed similar pattern in previous study.
The torque estimation equations are as follows.
1. Flexor
male: y=0.652x³-10.79x²+59.42x+2.155 (R²=0.999)
female: y=0.424x³-6.601x²+34.65x-3.975 (R²=1)
2. Extensor
male: y=4.572x³-54.51x²+161.7x+37.46 (R²=0.994)
female: y=1.522x³-21.77x²+71.92x+28.76 (R²=0.999)| 번호 | 참고문헌 | 국회도서관 소장유무 |
