Objective assessment of lower limbs explosive strength performed on the participants of the Polish Nationwide Special Olympics Football Tournament in the scope of both legs jump on the dynamographic platform

Introduction. Explosive strength is a motor ability defined as an ability to develop a maximum strength in the shortest time. It is an essential feature of many sportspeople, including football players. To assess this strength for lower limbs, the following tests are implemented: CMJ and DJ tests, defined determinants of McClymont reactive strength or K indicator according to Bartonietz. It is also possible to objectively assess the jump research with the use of a dynamographic platform. 12 Aim of the study. The aim of the research was to determine explosive strength of lower limbs with the use of GAMMA dynamographic platform. Material and method. The participants of the Polish Nationwide Special Olympics Football Tournament were examined with the use of the GAMMA dynamographic platform. 57 people aged 20-30 were researched (44 boys, 13 girls). On the basis of the results, lower limbs explosive strength was determined. Results. The research depicted a wide range of the lower limbs explosive strength values of the Football Special Olympics participants. This also suggests significant differences of motor abilities of particular participants taking part in the tournament. Conclusions. Results concerning the dynamographic platforms usefulness in assessing sportspeople motor abilities as well as explosive strength of young active participants of the Special Olympics were formed.
