Abstract:
This work refers to determining factors of skating performance in ice hockey. We suppose that the performance in the ice hockey tests is limited by some factors as the explosive power of lower limbs and dynamic balance. The skating tests with various difficulty and tests of maximal muscle strength of lower limbs, vertical jump with counter-movement and without counter-movement, standing long jump, single leg lateral jump from left and right foot and the test of dynamic balance on the right and left foot were put to the relationship analysis. In determining the performance limiting factors, we are coming up from the multiple correlations and regression analysis. For the reduction of indicators, the stepwise analysis was used. When speaking about the indicators of explosive power of lower limbs, the most influential parts of ice skating performance are the tests of muscle strength of lower limbs, lateral jumps and the vertical jump with counter-movement. Tests of dynamic balance have not been established as the limiting factors. The mentioned factors were showed as significant in the more challenging test as skating to the 5-7-5 meters (p<0,05) and in the Weave agility test (p<0,01). The complex of these factors explains significantly (p<0,05) with large effect (f²>0,35) the reliability of models on 55,0 % and 81,4 %. Selected tests, however, have shown as the statistically nonsignificant in the acceleration skating speed to the 10 meters and in Transition test. From the all ice skating tests, the highest consistency with the strength-power factors has the Weave test, which was proven statistically, practically and also by intercorrelation. An assumption about the impact of the explosiveness of lower limbs has been confirmed only in maximal muscle performance and in the lateral jump from the left and right foot.
