Asymmetry of supporting and stabilizing function of the lower extremities in alpine skiers
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2012, Vol 22, Issue 59
Abstract
[b]Introduction.[/b] Skiing like other sports has its own specific postural requirements for the competitor’s balance. The above specificity also refers to the asymmetry since each ski competition requires efficient mechanisms for bilateral control of athlete’s stability.[b]Aim of the study.[/b] Investigating the asymmetry level of stabilizing function in lower extremities of alpine skiers.[b]Material and methods.[/b] 11 participants, 3 women and 8 men – alpine skiers, were involved in the study aimed at identifying the level of functional asymmetry during stabilometric measurements performed with the use of stabliographic platform CQ Stab.[b]Results. [/b]The measurements reveal asymmetry mainly within the indicators of the frequency of correction foot pressure, the speed of oscillation and the surface area, and distance travelled by COP. Recorded values indicate the predominance of the left lower limb in a stabilizing function. This asymmetry does not manifest itself in distribution of mass but in worse indicators of the stability for this limb, especially in ML plane.[b]Conclusions.[/b] Asymmetry in stabilizing function found in young skiers corresponds to the observation made on not practicing skiing youth and adults. Further studies need to determine the relationship between the level of asymmetry and the effectiveness of a skier during the competition.
