A Research On Muscular Strength Application Characteristics During Release For Chinese Elite Female Throwers

In this paper, China's preparations for and participation in the 2008 Beijing Olympic Games in elite female athletes throwing the final exertion technology for the study, most of them athletes achieved the A standard Olympic Games in Beijing, and participated in the Olympics, the passing game, especially in women's discus throw and shot put items in The final achieved good results, this use of literature, expert interviews, bio-mechanical testing methods, bio-mechanics analytical method, trace observation, mathematical statistics and other research methods, to our outstanding female athlete throwing the Last Push muscle force during the main performance characteristics and skills, research, and technical performance of their situation analysis and diagnosis, in order to identify their problems with their technical characteristics and the main reason for guidance training practice, the main findings are as follows:1. Throwing in the single-support phase of the project time is not as short as possible, using a straight-line run-up form of a single-support phase of the project focus on faster, using translational plus rotational single-support phase of the project focus on slower, but the single-support time is too a long and unreasonable.2.Single-support phase (transition phase) anchor leg muscle in the side of speed, integral area of more than contra lateral muscles and legs at the side of lower extremity muscle strength was first issued, the discharge is higher than the contra lateral lower limb muscle, single-support Stage vacated legs touched the ground before the discharge levels of the rapid increase in the completion of the ground motion.3. Throwing events in single-supporting phase is vacated foot forward by way of a "pawing style" the land vacated feet touch the ground, some instantaneous power forward, not just play a supporting role, but also play forward, "pawing" role. 4. Throwing events during the final legs force to accelerate the timing of the main support in a single stage, rather than double-support phase, the direction of the right hip to throw his left leg extended, mainly in the plot of land, not in, after being left foot forward.5. Javelin throw, discus throw, shot put three single-support phase of the project, right foot forced the order is the first to the left pedal, then pedal forward, the final stretch upward tread.6. Double support phase (phase force), the left lower extremity muscles than the right side of the muscles of high discharge levels, the left lower limb muscles of the forced movement of the contribution of lower extremity muscles than the right, eventually forced the main action is on the left lower extremity muscles completed.7. Exertion phase of the right foot Javelin Throw tread force stretched the most, the timing of the latest wave of peak value, the left pedal extension, in order, the order is right, upward and forward, pushing his left foot shot put the project right tread extension of the timing of early-wave peak time there is a right turn, forward, up, left foot discus throw in the direction of peak force before and after the emergence of the latest, the left pedal in the direction of extension time was right, upward and forward.
