MUSCLE DAMAGE OCCURRING IN WHEELCHAIR SPORTS PEOPLE

Seven college-age healthy men exercised on a wheelchair treadmill to e valuate muscle damage that may occur from wheelchair propulsion. An ex perimental model in which a participant performs up-hill running in a wheelchair was prepared. Plasma creatinekinase (CK), myoglobin (Mb) an d lactatedehydrogenase (LDH) were measured as parameters. Blood sample s were taken pre-, immediately after-, 24 h after- and 72 h after the exercise. All of these parameters significantly increased after the ex ercise, but their time-courses were apparently varied. It is concluded that wheelchair propulsion causes muscle damage in certain situations such as up-hill running.
