Abstract:

The purpose of this study was to investigate the relationship between velocity and power values during loaded-squat jump exercise and agility characteristic in trained athletes. In accordance with this purpose, 62 athletes (age: 20,9 ± 1,92 years; height: 178,1 ± 4,83 cm; weight: 71,2 ± 7,37 kg) who competed in the different sport brances (kick box, karate, taekwondo, wrestling and football) participated voluntarily in this study. Subjects were performed to illinois agility test and loaded-squat jump exercise by using an external load corresponding to 40 % of their body weight and velocity and power parameters were obtained as mean velocity (MV), mean propulsive velocity (MPV) and peak velocity (PV), mean power (MP), mean propulsive power (MPP) and peak power (PP). In the analysis of data; descriptive statistics, Shapiro wilk test and pearson correlation anaylsis were used. According to the analysis results; average running times of participates in agility test was obtained as 15,8 (± ,51 sec). While velocity values during loaded squat jump exercise were obtained as 1.38 (± ,08 m/s) for MV, 1.55 (± ,11 m/s) for MPV, 2.58 (± ,17 m/s) for PV; power values were obtained as 389,2 (± 51,6 W ) for MP, 642,6 (± 118,1 W) for MPP, and 1119,4 (± 184,6 W) for PP. In addition it was determined that there was a high-level, negative and statistically significant difference between MV (r = - ,516; p<0.01), MPV (r = - ,434; p<0.01), PV (r = - ,461; p<0.01), MP (r = - ,518; p<0.01), MPP (r = - ,487; p<0.01) and PP (r = - ,514; p<0.01) with running times in the agility test. Accordingly, as velocity and power values during loaded squat jump exercise increases, running times in agility test decreases. As a result, it can be suggested that velocity and power values during loaded-squat jump exercise have a positive effects on agility performance.
