Analysis Of The Biomechanical Characteristics In The Support Technical Aspects In Men's 100m Running Phase

Running through the subjects meters Leg During kinematic data and EMG activities in the collection, then come to the relevant data in kinematic and EMG study. Hope that the data collected through the analysis and discussion, seeking elite 100-meter sprinter common special technical widespread phenomenon and principle, the final training for the project and methods of the theory provides a theoretical basis for and guidance. Materials and methods:This paper selected the six active sprinter is tested by a U.S. production Motion X ? high-speed camera and Germany to introduce the 16-meter lead Biovision EMG synchronization function tests, mainly men, support the technical aspects Running meters kinematic data and EMG indexes for the collection, kinematic data were independently developed by Shanghai Institute of Physical Education SBCAA & CAI SYSTEM-SBCAS kinematic processing software on each subject three times the effective data processing and data related to kinematics analysis. Surface electromyography of the original data processing software is BIOVISION EMG acquisition system comes with DasyLab10.0 software. Three times on each subject the raw EMG data were effective for high and low pass filtering (high pass which is 20HZ, low-pass for the 400HZ), remove noise and smooth the original data, then its full-wave rectifier, the negative wave into the normal mode; Finally, IEMG (IEMG), envelope, etc. dealing with the corresponding data.Conclusion:1) The center of gravity low athlete in the entire support phase of about 33.3% of time, the late stage after the tread is the body velocity increases the critical period, and the center of gravity vertical velocity of the late stage after the pedal gradually stabilized;2) After kicking in the buffer stage and phase of biceps femoris and semitendinosus muscle EMG was significantly higher than the contribution of a few other muscles, the muscles do work about 50% overall,Gluteus maximus is involved in development of the hip;3) Leg During muscle development effort in order are: gluteus maximums→rectus femoris→biceps femoris→semitendinosus→tensor fascia→lava tribalism anterior muscle, the trajectory of the development effort almost from the body side of the distal end of the transition;...
