EFFECT OF VERTICAL JUMP ON QUICKNESS, AGILITY, ACCELERATION AND SPEED PERFORMANCE IN CHILDREN SWIMMER

The purposes of this study were to examine effect of vertical jump on quickness, agility, acceleration, and speed performance. Method. A total of 20 girls and boys swimmers volunteered to participate in this research. The mean (SD) age was 11,50±1,64 years, height was 1,46±0,11 m, and weight was 40,50±10,02 kg for the 8 girls swimmers. The mean (SD) age was 11,40±1,59 years, height was 1,45±0,12 m, and weight was 39,80±13,58 kg for the 12 boys swimmers. we applied a testing procedure that included measurements of the quickness, acceleration, speed, agility, and vertical jump. We was applied pro-agilty test for agility. Quicness was evaluated for 5 m. Acceleration was evaluated using a 15 m. Speed was evaluated using a 50 m test. Vertical jump evaluated using a jumping mat with electronic system. Each test was applied three times, with a 3-minute interval, and the best result was recorded. Results.A significant relationship existed between quickness, agility, acceleration and speed with vertical jumping (P<0.05). A unit increase in vertical jumping lead to a change in the rate of 0,9 %, 5,5 %, 2,4 % and 9 % respectively in quickness, agility, acceleration and speed performance. In conclusion, when swimmers have highest vertical jump, they can more success in agility and speed. This skills is important for quickly turns, fathoms. Conclusions. Vertical jump effected quickly less than acceleration. This situation may change to another branch of sport and age group.
