| Popis: |
Up to now there are only a very few investigations of track start using EMG analysis. Despires (1973) compares standing start and crouch start technique and encounters significant advantage of the crouch start technique in terms of acceleration and load applied to the muscular system during the first second of the starting process. Jung (1984) measured electrical activity (EA) of four muscle groups of the rear leg using a telemetry device. Baranow (1973) studied the fact that the heel of the rear leg swings back during the push off phase because starting blocks normally support a part of the foot only. His result was that this causes a loss of time up to.12 s. |
