Trends in changes of elite sportswomen’ technique, specializing in 20 km race walk, considering rising of their sports results
AbstractPurpose: on the base of bio-mechanical characteristics’ analysis determination of trends in technique’s changes of elite sportswomen, specializing in 20 kilometers’ race walk, with rising of their sport results. Material: the research covered 13 elite sportswomen, specializing in 20 kilometers’ race walk (396 measurements). Results: bio-mechanical characteristics of the best 20 kilometers’ race walk sportswomen at Ukrainian championships 2014-2015 have been elucidated. Comparative analysis of elite sportswomen, having different sport results, has been conducted. Conclusions: improvement of sportsmanship to world level (from 1:38:37 to 1:31:35) takes place at the account of increasing of step length to 1.10 m (S = 0,01); shortening of phase of single support X average = 0.26 sec.; S = 0.01) owing to reduction of shock absorption time to 0.08 sec.
