Abstract


The aim of this study is to determine the influence of explosive strength and sprinting speed on a group of selected tests of agility. The sample of participants consisted of 77 second-year students of the Faculty of Sport in Ljubljana (28 females and 49 males). The tests of general motor skills were focused on the targeted motor characteristics of the participants (speed, agility, strength). The tests of agility and speed were measured using the Brower Timing System(Salt Lake City, UT, USA), and the tests of explosive strength using the Opto Jump (Microgate, Bolzano, Italy), an optical device which measures the duration of the contact and flight time, while the strength of the hand squeeze was measured using a Hydraulic hand dynamometer (Baseline, USA). The study determined a high correlation between speed and the criterion variables, especially in situations in which the eccentric-concentric contractions are not pronounced (zig-zag movement, lateral movement), and recognized the influence of the countermovement jump as a significant predictor in the manifestations which are characteristic of eccentric-concentric contractions.
