Abstract

Relevance: Sporting activity contents consists of the various movements and actions. Their diversity is the result of the specificity of sports, training direction and competition rules. The main improvement direction of the athletes’ motor skills is teaching of motions and actions, increasing their diversity and aggravation of the performance conditions. Jumps performed in different directions are an integral part of the movements in majority of sports. They are performed with the interaction of the body and its support. Many difficult movements and actions are performed during playing basketball, but the impact of various jumps on basketball player motor skills and their general and specific preparedness is still not investigated enough, so there exist the reserves of its improvement (Karoblis, 2005; Stonkus, 2003; Radžiukynas, Muckus, 2006; Latash, Zatsiorskij, 2001). The aim of the study was to establish kinetic and kinematical indices of different directions jumps of Lithuanian basketball players (n = 76). Research methods: 1. Testing. 2. Tensodinamometry. 3. Mathematical statistics. The object of investigation is the jump of different directions, running. Research subjects were basketball players of different ages and skills level. It was found that the basketball player’s motor skills by jumping on the horizontal axis, an angle 45° to on the sides taking off with the both, left and right foot was statistically better compared with the same direction jumping backwards. Vertical jumps, taking off with both feet kinematic (take-length, jumping height) and kinetic parameters (take-off force, the relative power, leg muscle reactivity, the overall taking off-speed power potential) were better than the same indices taking off with left and right legs. Body movement speed and jumping height during 30 s vertical jumping (x = 44 jumps) taking off with one foot, from 7 s to 30 s reduced significantly (p < 0,025). Jumping indices has an influence on the body movement in horizontal direction (acceleration) results. Fast 30-60 m sprint from high start showed a high correlation relationship with the jump height, and length taking off with both feet, 30 m jumping on one foot forward, and the long jump taking off with the left foot in 45° angle forward right. Athletes - basketball player’s motor skills through various direction jumps and fast running are not the same and depends on the directions of body movement, jumping duration, of the transition period, the body position and amplitude of movements, taking off duration, strength, power.
