A Study on The Deaf’s knee Isokinetic Muscular Strength

&nbsp;&nbsp;The purpose of this study was to investigate and compare knee Isokinetic muscular strength of deaf and normal population.<BR>&nbsp;&nbsp;For this purpose, 32 subjects(8 untrained deaf, 8 trained deaf, 8 deaf national athlete, 8 untrained normal) were selected.<BR>&nbsp;&nbsp;The results were as followings.<BR>&nbsp;&nbsp;1. The peak torque in time of flexion 60°/sec(right, left) showed great significant difference(p＜.001), 180°/sec 5, 25 repetitions(left) showed great significant difference(p＜.01) and 240°/sec(right) showed significant difference(p＜.05). The peak torque in time of extension 60°/sec(left) showed great significant difference(p＜.01), 60°/sec(right), 180°/sec 5 repetitions(left), 25 repetitions(right, left) and 240°/sec(right, left) showed significant difference(p＜.05). And the others showed no significant difference.<BR>&nbsp;&nbsp;2. The peak torque%body weight in time of flexion 60°/sec(right) showed great significant difference(p＜.01), 60°/sec(left) showed significant difference(p＜.05). The peak torque%body weight in time of extension 60°/sec(left), 180°/sec 25 repetitions(left), 240°/sec(right) showed significant difference(p＜.05), 240°/sec(left) showed great significant difference(p＜.01). And the others showed no significant difference.<BR>&nbsp;&nbsp;3. The total work(BWR)%BW in time of flexion 60°/sec(left) showed significant difference(p＜.05). The total work(BWR)%BW in time of extension 60°/sec(left), 180°/sec 25 repetitions(left), 240°/sec(left) showed significant difference(p＜.05). And the others showed no significant difference.<BR>&nbsp;&nbsp;4. The average power(BWR)%BW in time of flexion 60°/sec(right, left) showed great significant difference(p＜.01). The average power(BWR)%BW in time of extension 60°/sec(left), 240°/sec(left) showed great significant difference(p＜.01). 240°/sec(right) showed significant difference(p＜.05). And the others showed no significant difference.<BR>&nbsp;&nbsp;5. The endurance ratio in time of extension 180°/sec 25 repetitions(left), 240°/sec(left) showed significant difference(p＜.05). And the others showed no significant difference.
