The reflection kinesiology analysis of cross country skiing - classical technique diagonal stride and herring bone
Abstract
The study brings the comparison of the representative coordination parameters during cross-country skiing - classic technique-diagonal stride and herringbone. There was watched the kick in the compara-tive analysis because the kick is determinative for propulsion.
The activation of selected muscles on the legs during the skiing was monitored with surface electromyography. For the pinpoint of the boundary between two followed movement cycles, we used the synchronized accelerometer.
The gained data was processed by SW Mega Win and MatLab and analysed by the progressive triangle method and compared by ANOVA1. The monitored group was created by seven men who were members of Czech Cross-Country Ski Team.Base on the monitored data we may presume the high level of the lateral similarity of cross-country skiing classic technique and herringbone as well.
The base of significant differences in the muscles activation was found in the present the glide phase of movement cycle. The glide phase is very impor-tant during the diagonal stride cycle while the herringbone step is not contained any gliding.
During human phylogenies, no animal uses any gliding so the gliding by the diagonal stride is not nature and the man have to learn it.
