Description
We investigated the effects physiologic genu varum on side-step cutting performance. Eight bowed leg subjects and eight normal knee subjects between 18 and 23 yrs of age were recruited for this study. Participates performed each three trials of jump as quickly as possible to the front, back, left and right direction without reaction movement of arms. Floor reaction force and muscle reaction time were estimated from vertical force signal and jumping distance were measured. Although there were no alteration in maximum floor reaction force and jumping distance in jump performance to the all directions between both type subjects, bowed leg movement elicited a significant decreased contact time and increased rate of force decline in jump performance to the right and left directions. These results provide suggestion that subjects with genu varum compared with normal knee possess an advantage in muscle. reaction time during side-step cutting.
