<strong>AIM:</strong> The purpose of the present study<b> </b>was to investigate the correlation between acceleration and maximum running phase in 60-m sprint and vertical jump performance. Furthermore, to investigate the factors that affect the acceleration phase, maximum running phase, and overall 60-m sprint performance. <b>MATERIAL & METHOD:</b> Participants were 25 young amateur athletes, aged 18 ± 1 years, with body mass 64.64 ± 13.39 kg and body height 1.71 ± 0.11 m. We examined the correlation between the acceleration phase (0−30 m) and maximum running phase (30−60 m) and 60-m sprint performance, measured with photocells (Optojump), and vertical jump performance (take-off velocity, jump height, maximal velocity, maximal power), measured with a force plate (Bertec). Pearson correlation was used to examine the correlation between the forementioned parameters (SPSS, v. 21). <b>RESULTS: </b>There was a correlation between jump height and 60-m sprint performance (<i>r </i>= −0.713, <i>p < </i>0.001), maximum running phase (<i>r </i>= −0.512, <i>p = </i>0.15), and a weak correlation with acceleration phase (<i>r </i>= −0.495, <i>p</i> = 0.19). There was a correlation between take-off velocity and 60-m sprint performance (<i>r </i>= −0.732, <i>p < </i>0.001), maximum running phase (<i>r = </i>−0.553, <i>p = </i>0.08), and a weak correlation with acceleration phase (<i>r = </i>−0.472, <i>p = </i>0.27). There was a weak correlation between maximal velocity, acceleration phase (<i>r = </i>0.439, <i>p </i>= 0.41), and 60-m sprint performance (<i>r = </i>0.438, <i>p = </i>0.42). There was a correlation between maximal power and 60-m sprint performance (<i>r = </i>−0.739, <i>p < </i>0.001), acceleration phase (<i>p = </i>−0.635, <i>p = </i>0.02), and a weak correlation with maximum running phase (<i>r = </i>−0.437, <i>p = </i>0.042). There was a correlation between 60-m sprint performance and maximum running phase (<i>r = </i>0.792, <i>p < </i>0.001) and acceleration phase (<i>r = </i>0.596, <i>p = </i>0.03). Finally, there was a correlation between body height and 60-m sprint performance (<i>r = </i>−0.738, <i>p = </i>0.02) and maximum running phase (<i>r = </i>−0.666, <i>p = </i>0.07). <b>CONCLUSIONS:</b> According to our results, 60-m sprint performance was highly correlated with body height, maximum running phase and all the vertical jump parameters (explosive power), except for maximal power, which had a high correlation with the acceleration phase (sprint acceleration).
