| the purpose of this article focus on normal gait of young men about the dynamics analysis of lower limb.The main method is experiment in this paper(VICON capture system,ATAM force platform,V-3D and LIFEMOD software),15 sophomore male students are selected as the subjects from the health department of Nanjing sport institute.The test of gait required that the subjects put on shoes and swimming trunk.The results: the average stride length: 1.419 m,the step width: 0.134 m,the pace: 1.341 m/s,the stance percentages: 60%,the swing percentage: 40%,the double stance time: 0.122 s,the average range of ankle angle: flexion and extension: 31°,adduction and abduction: 18°,intorsion and extorsion: 18°;Knee angle flexion range of motion: flexion and extension: 76°,adduction and abduction: 15°,intorsion and extorsion: 19°;The hip angle: flexion and extension:44°;adduction and abduction: 12°;intorsion and extorsion: 18°;The first peak GRF : 1.21,the minimum GRF 0.74;The second peak GRF : 1.09;The biggest strength value on the anterior tibial muscle act on the end stance period and the early swing period(0.42N/kg and 0.40 N/kg).Conclusion: the model is successful that imitates the the force value of muscle in gait. |
