Biomechanical substantiation of handicap in powerlifting for athletes with a disability | [Biomechaniczne uzasadnienie wyrównywania szans w trójboju siłowym dla niepełnosprawnych lekkoatletów]

Abstract

The aim of the research was to create a handicap model in powerlifting for athletes with a disability. Best athletes participated West Ukrainian Regional competition in 2007 were examined. The model of handicap was created on the estimation of the motor possibilities level of disabled athletes, based upon muscle testing. There is a strong positive correlation between the offi cial competitive result and the result of muscle testing that makes clear to calculate a compensation coeffi cient as a ratio of its maximally possible result to the individual muscle testing result. Objectivity of muscle testing is confi rmed by the signifi cant strong correlation between the offi cial competitive result and the result of dynamometry, and also correlation between muscle testing and dynamometry. Thanks the compensation coeffi cient the sportsmen with harder impairments moved to better positions. The most important role in the determination of the winners remains for the offi cial competitive result that is proved by winners’ rank stability
