The effects of fatigue on the mechanics of forward maximum velocity power skating in skilled and less-skilled skaters.

摘要

To compare the effects of fatigue on the mechanics of maximum velocity power skating, 16 subjects (eight skilled, six less-skilled) were videotaped using two cameras while subjects performed a maximum exertion test covering 380 metres. Subjects were assigned to the skilled or less-skilled group based on their individual task times. Mean task times were 57.09 seconds for the skilled group and 63.12 seconds for the less-skilled group. The task required subjects to start, skate forward, and stop. Subjects were videotaped over three trials. The two views for each trial were digitized and transformed into one three-dimensional view via a human motion analysis program. Analyses of variance tests were conducted for each dependent variable to indicate differences in the skating mechanics between skaters of different skill levels and changes that occurred due to fatigue. Few differences were found between the skilled and less-skilled group. Several changes in the mechanics of the skating pattern occurred with fatigue. (Abstract shortened by UMI.)Dept. of Kinesiology.
