The aim of this study was to examine the relationships between short sprint time (30 metres) and several kinetic variables of the countermovement jump (CMJ) in a sample of trained athletes. A group of 12 trained athletes volunteered to participate in the study (mean ± SD: age 22.2 ± 1.2 years, body mass 67.5 ± 5.5 kg, body height 1.75 ± 0.02 m). Following a standard warm-up, participants performed three maximal CMJ trials on a Smith machine and three maximum effort sprints of 30 metres. The major findings of this study were the significant associations between 30 metre sprint time and the concentric phase of CMJ for both force and power parameters. In addition, non-significant predictive values were observed between sprint performance time and jump impulse values. The results are of practical interest for optimising training and assessment methods in sprint performance.
