Research Of The Effect Of Teaching On "Ahead Of Apparatus" Throw Direct Force Of The Hip Extensor Resistance Exercise

Objective: To direct the force of hip extension exercises on resistance Shot"ahead of apparatus"Throw the effect of teaching to explain the biological mechanism of this method. Methods: This study used exercise testing and comparison studies. The subjects were never received technical training in 20 throwing ordinary male college students. The experimental group (10 people) used to design the direct force of hip extensor resistance training method and self-developed hip directly after the pedal force to conduct special training device technology to enhance practice of group: respectively, including 1) directly affected by heavy load force kicking hip Shot Put device in situ positive side to vote and to vote, 2) small load force directly kicking hip devices cast front and side shot cast in situ, and 3) to vote and hand the positive side shot cast in situ. Control group (10 persons) using the traditional training method for training hand technique, and strength training using weight-bearing squat and other exercises with the experimental groups were balanced load. Results: 1) the experimental group after the test the shoulder horizontal plane hip angle (clockwise) than the control group, (P <0.05; 2) Shot in experimental group after the test position to the maximum from the preparation process equipment beyond the horizontal displacement of the hip was than the control group P <0.05, shoulder horizontal displacement and the control group no significant difference P> 0.05; 3) the experimental group after the experiment beyond the equipment Shot to shot from the largest horizontal displacement of the shoulder was significantly greater than during the control group P <0.05 ; 4) Shot in situ after the test side of the experimental group dropped from the preparation position to the maximum beyond the device process (before the half) and from the biggest shot beyond the instruments to the process (after half) the level of shoulder movement time compared with the control group had no significant difference P> 0.05; 5) in situ after the test side of the experimental group dropped shot after shot moving average speed was significantly greater than half the control group P <0.01; 6) Shot in situ after the test side of the experimental group performed significantly better than throwing in control of lead group P <0.01. Conclusion: 1) directly affected by the force of the hip extensor resistance exercise can significantly improve the ability to stretch the hip; 2) directly affected by the force of resistance exercise can significantly improve hip extension beyond the range of instruments; 3) directly affected by the force of the hip extensor resistance exercise can significantly improve the shot Throwing the second half is beyond the equipment from the largest to the shot shot in the process of the average speed; 4) directly affected by the force of the hip extensor resistance exercise can significantly improve the shot put results; 5) directly affected by the force of the hip extensor resistance exercise in the shot " Beyond equipment, "Throwing technology training exercises than traditional hand has a better training effect.
