碩士 === 國立體育學院 === 運動科學研究所 === 83 === The aim of this research is to compare the differences between two leg positions as applied in a forward or sideway kick we select five male students from a Taipei City university as the ones to take our tests. we ask each of them to perform four kinds of kicks:forward kick with a straight leg, sideway kick with a straight leg, forward kick with a leg stretching from their movements a set of data concerning the vertical reactionary forces from the ground which the testees have met, and electromyofraphical responses on the muscles of the legs which deliver the kicks Our conclusion is as follows: 1.The results of the tests confirm that the toes of the right leg which launches a kick in a straight position would reach maximum harizontal and combined speeds as they move past the "Third Point" meaning a point where the ankle of the kicking leg overlaps the nonkicking leg as seen from a side view. Such speeds are obviously faster than those shich kicks with legs stretching in attacking the lower body of an opponent. 2.The knee of the right leg which strikes a kick from a bowed position would claim much faster horizontal, vertical and combined speeds than its straight leg kick's. counterpart The three sorts of speeds mentioned above all happen before the appearance of the "Third Point." 3.The angle speed for the hip joint of the right leg which delivers a kick from a bowed position would be considerably faster than that for the straight leh kick. A maximum of the speed would ocurr right after the "Third Point" appears. Therefore a bowed knee would be much gelpful in making a powerful kick.
