Biomechanical Analysis On The Fore Hand Straight Punch Technique Of 64 Kg Male Boxer Of Shandong Province

Research purpose: This research basis on the technology using statistical of male boxer of Shandong province in several domestic and foreign game. The research analysis the common and weak technical movement of athletes. Finding athletes technical movement existing strengths and weaknesses. Revealing each body joints trajectory and the relationship between the strike force. Put forward technical movement weakness of training methods. Provide training for athletes follow-up, powerful support for this project by potential advantage projects to advantage projects change make contribution.Research methods: High speed cameras and Kistler force-plates were synchronized to test the technique of five 64kg first-line male boxers (age:23.5±2.3year, height: 180.7±3.5cm,weight:63.6±1.5kg, training experience: more than 4 years)and five second-line boxers (age:16.5±1.7year, height: 177.4±2.2cm,weight: 64.8±2.3kg, training experience: 2-4 years) of Shandong province.Research results:1.Kinematics analysis Struck moment maximum speed of 64 kilograms first-line male boxers of Shandong province is 7.1±0.7 m/s. Elbow angle is 126±8; Pedal anchor knee angle is 165 + 5. Maximum speed of second-line boxers is 6.4±1.1 m/s. Elbow angle is 108±12. Pedal anchor knee angle is the 145±6. The speed loss value of first-line boxers is 0.52±0.17 m/s. The speed loss value of second-line boxers is 0.25±0.8 m/s.2.Dynamics analysis: Maximum vertical direction pedal fertility of 64 kilograms first-line male boxers of Shandong province is 1.05±0.09 times of their body weight, The biggest strike force of vertical direction is 5.88±0.21 times of their body weight. Maximum vertical direction pedal fertility of second-line boxers is 0.59±0.12 times of their body weight. The biggest strike force of vertical direction of is 4.60±0.18 times of their body weight. Conclusion: 1. Boxing speed of Straight Punch of 64kg first-line male boxers of Shandong province is slower than the elite boxers in the world. When first-line boxers play Straight Punch, the shoulder straight to punch process has some deficiencies.2. Pedal stretch of 64kg second-line male boxers of Shandong province is not completely, the pedal productivity of them is small, the Shoulder/hips rotating amplitude is small and the speed loss value of them is big. All of them impact the strength, struck distance and strike struck maximum speed of 64kg second-line male boxers of Shandong province.3. Most of 64kg male boxers of Shandong province play Straight Punch do not accordance with Lower limbs- torso- Upper limbs. The pedal stretch of some boxers is not completely.
