Study of contribution rate for the main body momentum of the total momentum through take off in high jump Fosbury style

Abstract

Abstract:Movement quality greatly affect performance through take off in high jump activity. The athlete make good performance to achieve the best and this requires the participation of all body parts in the performance. The study aims at Identifying the main body momentum of the total momentum through take off in high jump Fosbury style. The researcher has used the descriptive method for its appropriates. The study sample consists of four jumpers who obtained the first ranks in Iraqi Youth Championship held at Erbil. Sport Club Team Stadium. Then the researcher used the following software: I-film, Premier, ACD See, AUTO CAD 2000 and Excel. The researcher also used statistical tools including mean, standard deviation and contribution ratio. The study concluded that the leading leg occupied the first rank with a ratio (0.998), then the trunk with a ratio (0,995), then the two arms with a ratio (0,963, 0,909) respectively, then the take off leg with a ratio (0,881).
