The purpose of this research was to identify the relationship between jump test results and acceleration phase of sprint performance in national and regional 100m sprinters. Fifteen male (age 21.89 ± 3.26 years; body height 1.72.66 ± 3.20 m; body mass 61.35 ± 11.40 kg; 100 m personal best: 11.67 + 0.46 s {11.00 - 12.19}) track sprinters at a national and regional competitive level performed 10 m sprints from a block start. Anthropometric dimensions, along with squat jump (SJ), countermovement jump (CMJ), continuous straight legged jump (SLJ), single leg hop for distance, and single leg triple hop for distance measures of power were also tested. Pearson correlation analysis revealed the single leg hop for distance with front and back leg (respectively, r = -0.74 and r = -0.76; p = 0.021 and p = 0.017), and the single leg triple hop for distance with front and/or back leg (respectively, r = -0.84 and r = -0.89; p = 0.004 and p = 0.001), generated capabilities to be strongly related to sprint performance. Further linear regression analysis predicted an increase in the single leg hop for distance with front and back leg of 10 cm, to both resulted in a decrease of 0.07 s in 10 m sprint performance. Further, an increase in the single leg triple hop for distance with front and/or back leg of 10 cm was predicted to result in a 0.08 s reduction in 10 m sprint time. The results of this study seem to suggest that the ability to gain more distance with the single leg hop and the single leg triple hop for distance to be good indicators for predicting sprint performance over 10 m from a block start.
