Research On The Theory System Of Physical Ability Of Chinese Top Men 100m Sprinters

The theoretical system of physical ability of 100m is a whole which consists of physical ability concepts,consistence and connection,the ways to achieve physical ability and the factors to promote and limit physical ability;the factors that affect physical ability;the factors that promote and improve physical ability.In process of motor performance,the functional state includes the period of process of keeping particular level and fatigue period.Sports fitness has five actions or moves process:slowing down and staring move,sporting acceleration,moving endurance,kinetic flexibility and moving nimbleness.The physical ability includes body form and structure,body function and sporting quality in any athletic events. The component of body form and structural parameter and sporting fitness have specified difference,only because of the difference of the athletics' characteristic in the events.Taking this as basis,the study has set forth the concepts and formation parameter of fundamental physical ability and majoring physical ability.At the same time,it analyzes and understands the concepts of physical ability of 100s.According to the athletic characteristics and the concepts of physical ability,the study has taken over the structural component and interrelation in 100ms physical ability elaborately.With training level improving the 100m athletes' step and tempo is a synchronous increase process at any times in 100m.Its reason is related to the difference of motor ability.The changes of step and tempo are that they increased synchronously,then change into the step continue increasing and the tempo increase slowly relatively,at last there are great extant of the step continue increasing and the tempo increase slowly relatively,Its reason has something to do with output rating size of the main energy resources metabolic muscles contraction in each moving phase.In training from lower level to middle level,100m athletes' step increase and time reduce are basic on the increased parts of supporting distance more than the reducing parts of flying distance,and through cutting down the displacement time of unit step distance to keep the displacement increasing and step time reducing in pace. And 100m athletes' step increasing and time reducing are basic on the increasing of step supporting distance and time,in training from advanced level to top level,and through cut down the displacement time of unit step distance and flying time to cause the reducing time of flying more than increasing time of supporting to fulfill the displacement distance increased and time reducedWhen the human runs 100m by unreasonable movement rhythm,the distance and time were affected and surely prolonged relatively by comprehensive fatigue, but by reasonable movement rhythm,the result is on the contrary.The fatigue degree of motion is the reason of balance or unbalance of motion speed and energy consumption when the motor performance slows down,and also leads to different various result at the end of time.To the 100m athletes,at any training level,their fastest speed at the procession of 30m is quicker than that of runninglOOm by reasonable movement rhythm.Their fastest speed at the procession of 30m is the basic to improve various local ability that running by reasonable movement rhythm.
