Changes in kinesthetic differentiation capacity in the ski learning process
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2008, Vol 18, Issue 44
Abstract
[b]The aim of the study[/b]. To investigate the changes occurring in kinesthetic differentiation capacity as a result of ski exercises. It has been assumed that in the process of learning new motor skills the sensations generated in the motor apparatus are increasingly differentiated, and that can be measured using the methods described hereunder.[b]Methods[/b]. The standard deviation from the initial model pressure expressed in kG and referred as pressure repeatability indicator (WP) has been defined as the measure of kinesthetic sensitivity (kinesthetic differentiation capacity). Pressures have been exercised alternately by the right and left foot on the kinesiometer platform equipped with tensometric sensors. They were then quantified through the medium of an analogical-digital processor and collected into individual files by a special computer programme.The measurement of the progress made in learning ski techniques (Haczkiewicz test) in the research was carried out in the same way as the tests undergone by students on the first day of their ski programme to divide hem into competence groups. The run times were measured to 0.01 second. The data was collected between the second and the ninth day of the ski programme. The progress was measured classically on a simple slalom. The test trajectory was defined by 10 single slalom poles disposed with 10 meter intervals. The slope inclination was 15–20 degrees.[b]Conclusions[/b]. In the process of motor learning (skiing) the perception of the sensations generated in the motor apparatus is progressively perfected. It has been confirmed that impulses from the motor apparatus and touch receptors can play an essential role in developing cutaneous and muscular sensitivity, which is proved by tests in ski boots and sport shoes. Multidimensional relationships between kinesthetic sensitivity indicators and the efficiency of ski learning point to the fact that the sensitivity of the signals linked to conscious motor perception can change along with the progress in motor learning. It is of fundamental importance and must be confirmed in other fields (swimming, shooting or figure skating).
