Eccentric and concentric torques of knee and elbow extension in young and older men.

摘要: The purpose of this study was to compare the strength knee extensors and elbow in young older men under conditions eccentric loading concentric contractions. Twelve ages 23 32 years 12 60 75 were tested at two angular velocities movement, 90 180 degrees.s-1, on a KinCom isokinetic dynamometer. Compared men, had lower peak torque values for (31%) (32%) (p less than 0.05). group showed torques all comparisons (21% lower), extension slower velocity (20%). At faster velocity, did not differ from that younger men. Differences between age groups significantly muscle action one. observation maintained particularly fast warrants research defining mechanism.
