Sažetak
Introduction: Most programs are design to improve strength and power in an effort to translate these improvements into decreases in sprint and change of direction times (Nimphius, McGuigan, & Newton, 2010). However, findings concerning relationships between power, speed and change of direction speed have been somewhat equivocal (Barnes et al., 2007). Therefore, the purpose of this study was to determine the relationships between sprint, change of direction speed and jump performance of young female volleyball players. Methods:Forty two national level young female volleyball players (age = 13.5±0.6 years, and 4.5 years of experience) participated in this study. The jumping ability of each player was determined using squat jump, countermovement jump (CMJ), and countermovement jump with arm movement (CMJAM). Speed on 5, 10 and 20m and the T test were assessed to determine the change of direction speed and sprint performance. Magnitude of effect for the correlations was based on the following scale. trivial:, 0.10, small:˂0.10–0.29, moderate:˂0.30–0.49, large:˂0.50–0.69, very large: ˂0.70–0.89, and nearly perfect: ˂0.90 (Hopkins, 2014). Results: The results of the Pearson correlation analysis indicated moderate to large correlations between jumping ability and change of direction speed (p˂0.01 ; r=‐ 0.418 to ‐0.514). Similarly, jumping ability showed moderate to large correlations with sprint performance with smallest correlation found between speed on 5m and jumping ability (p˂0.05 ; r = ‐0.320 to‐0.354). However, the results of correlation analysis indicated large correlation between speed on 10m and jumping ability (p˂0.01 ; r=‐0.554 to ‐0.602). Discussion & Conclusion: Because jumping ability is an obvious potential performance predictor for volleyball it is important to see if it is related with both, sprint and change of direction speed performance. The relationship between speed, change of direction speed and jumping performance found in this study is also in agreement with other studies in other sports. This suggests that training in the vertical domain may increase speed and change of direction performance.
