Abstract

ORIG EN

V originále

Among sport conditioning coaches, there is considerable discussion regarding the corelation between different types of speed and explosive power of lower limbs. However strong correlations between maximal strength output and explosive power output have been already proven. The aim of this study was to refute or confirm the conclusions of other researchers. Twenty semi-elite football players (n = 20; 25.1 ± 6.2 years) participated in the study. All participants were assessed using the following 5 tests: countermovement jump (CMJ), 5-0-5 Agility test with dominant lower limb turn and non-dominant lower limb turn, 10-meter linear sprint, 30-meter linear sprint to measure speed (acceleration, maximum speed, and change of direction speed) and explosive power. Pearson’s correlations (p ≤ 0.05) calculated the relationship between CMJ and speed tests. Subjects displayed a very large correlation between 10 and 30-meter sprints and CMJ (r = −0.75 and −0.76). There was a moderate correlation between 505 COD tests (non-dominant and dominant) and CMJ (r = −0.54 and −0.61, respectively). There are large to very large relationships between speed and power attributes in semi-elite soccer players, especially between linear speed and CMJ. Improving the explosiveness and power of lower limbs can lead to increasing velocity and enhancing sport-specific speed.
