Using Of Special Ability Indicators In Race Walking Athlete Selection

Purpose:1) Make clear the function, physical exercise capacity and special features of elite race walkers; 2) preliminary explore the index of athlete selection such as function, physical fitness and exercise capacity in specialized training.Methods:118 athletes who participate in the International Race Walking Challenge (National Race Walking Championships) in 2009 were involved in the study. International exercise master and exercise master is the outstanding group, levelâ… andâ…¡athletes is the general group. We used literature methods, expert interviews methods, experiments and mathematical statistics methods in this study.Results:1)The hemoglobin (Hb) level, a function indicator, is significantly higher (P<0.05) in female elite group than in normal group. The serum testosterone (T) levels of male and female walking athletes is significantly higher (P<0.05) in elite groups than in the general groups.2) Hip rotation around the roundabout, coordination test scores, two physical indicators, the female elite group were higher than normal group, and have significant differences (P<0.05). And for the men group this phenomenon was also happened together with the around the roundabout twist angle (P<0.01).3) Exercise capacity in specialized training has three indicators:5 KM best results,10KM best results and 20KM best results. The general group of female were lower than the expert group (P<0.01).5KM best result of male general race walkers was lower than the elite (P<0.05),10 KM and 20 KM best score was much significantly lower (P<0.01).4) We use factor analysis method to analysis the three indicators,5 KM best results,10KM best results,20KM best result, fined that two indicators is the principal component indicators:the first factor-endurance factor; second factor-speed endurance factor. Best influenced 20 KM and 5 KM race.Conclusions:1) Elite race walkers of our nation have normal immune function, aerobic ability, protein synthesis ability, muscle strength and good quality. Hemoglobin, serum testosterone can be used as functional aspects reference of elite walkers selection.2) Elite walkers of our nation have good ankle joint mobility and flexibility, fine lumbar spine and hip flexibility, strong stretch ligaments of surrounding muscles, so their body control ability is good, and can keep walking techniques during training and competition to improve athletic performance. Outstanding Female Race Selection indicators include physical aspects of hip rotation and coordination test scores; Elite male walker physical aspects of selection of indicators, including swivel angle, hip rotation and coordination test scores.3) Elite Walkers have good endurance and speed endurance capacity.5KM Race best results,20KM Race best results can be chosen as a good selection reference factor on athlete capacity.
