On The Characteristics Of Identical Elements And Different Structures Of The Lower Limbs'Pedalled And Stretched Strength For Some Physique Dominated Event-group Sportsmen

The characteristics of identical elements and different structures of the strength abilities for sportsmen denote such a phenomenon that the strength abilities of different spoilsmen have the same constituent elements (maximal strength, speed strength, reactive strength and strength endurance), but the strength ability structures, which are composed of each element are different. With the example of some physique dominated event-group and the pedalled and stretched movement of lower limbs, this paper has made a demonstrated study of itWith advanced strength testing apparatus and proper strength testing methods, it has taken quantificational tests of the actual development of the maximal strength, speed strength, reactive strength and strength endurance of the lower limbs' pedalled and stretched strength for the sportsmen at different competitive levels and different sexes who are engaged in the events of weight lifting, sprinting hurdle, jump, throwing and middle and long distance running. A multi-morphological structure model of the lower limbs' pedalled and stretched strength ability has been established. The study has shown that the ability of the lower limbs'pedalled and stretched strength for athletes and weightlifters belonging to the physique dominated event-group has a significant feature of "identical elements" and "different structures".The main conclusion as follows:1 The "identical elements" is one of the main characteristics of the lower limbs' pedalled and stretched strength for weightlifters and athletes belonging to the physique dominated event-group.2 There exists a difference in various degrees among the developing levels of 4 compositive elements of the lower limbs' pedalled and stretched strength for weightlifters and athletes belonging to the physique dominated event- group from different events, at different competitive levels and with different sexes.3 The different structure model of the lower limbs pedalled and stretched strength for weightlifters and athletes belonging to the physique dominated event-group from different events, at different competitive levels and with different sexes. It has shown the diversity of ability structure of the lower limbs'pedalled and stretched strength and the general existence of the characteristics of "different structures". A series of structure models established by this study can be used for reference in the strength training practice.4 A certain difference has existed in the relation forms of each element of the lower limbs' pedalled and stretched strength for the sportsmen who are engaged in the events of weight lifting, sprinting hurdle, jump, throwing and middle and long distance running. Itrepresents the differences of coefficient correlation and the statistical significance. In allone-to-one interrelations, only both maximal strength and speed strength remain a closerlinear correlation. Either loose linear correlation or non-linear correlation exists amongother elements.The lower limbs' pedalled and stretched strength is dependent on the combined action ofthe maximum and speed strength factor, reactive strength factor, strength endurance factorand comprehensive factor. The 4 factors have reflected the most parts of information of thewhole strength ability.The factor which plays a dominant role in the lower limbs' pedalled and stretched strengthfor the sportsmen who are engaged in the events of weight lifting, sprinting hurdle, jump,throwing is the maximum and speed strength factor. The dominant factor in the lowerlimbs' pedalled and stretched strength for middle and long distance runners is the strengthendurance factor.The reactive strength factor in the lower limbs' pedalled and stretched strength for bothjumpers and throwers is the secondary dominant factor. It has reflected that they need thereactive strength more than that in other events.The secondary dominant factor in middle and long distance runners is the maximum andspeed strength factor and it is ra...
