Abstract

This study examined the force-velocity and power-velocity relationships of the quadriceps muscles of children and adults. Measurements of muscle function were collected using the Contrex isokinetic dynamometer. Twenty adults and twenty children performed maximal effort knee extensions at nine different velocities. ANOVA revealed significant differences in the absolute values of peak torque and power between the two groups. When power values were corrected for lean muscle volume, no significant differences were found between the two groups.
