Background:Marginal changes in the execution of competitive sports movements can represent a significant change for performance ***,such differences may emerge only at certain execution intensities and are not easily detectable through conventional biomechanical *** study aimed to investigate if and how competition standard and progression speed affect race walking kinematics from both a conventional and a coordination variability ***:Fifteen experienced athletes divided into three groups(elite,international,and national) were studied while race walking on a treadmill at two different speeds(12.0 and 15.5 km/h).Basic gait parameters,the angular displacement of the pelvis and lower limbs,and the variability in continuous relative phase between six different joint couplings were ***:Most of the spatio-temporal,kinematic,and coordination variability measures proved sensitive to the change in ***,non-linear dynamics measures highlighted differences between athletes of different competition standard when conventional analytical tools were not able to discriminate between different skill *** relative phase variability was higher for national level athletes than international and elite in two couplings(pelvis obliquity—hip flex/extension and pelvis rotation—ankle dorsi/plantarflexion) and gait phases(early stance for the first coupling,propulsive phase for the second) that are deemed fundamental for correct technique and ***:Measures of coordination variability showed to be a more sensitive tool for the fine detection of skill-dependent factors in competitive race walking,and showed good potential for being integrated in the assessment and monitoring of sports motor abilities.
