Power output is acknowledged as an indicator of physical condition for athletes. Vertical jump height is a good predictor of muscle strength (power output), and therefore several types of vertical jump tests have been used to evaluate athletic performance. The aim of this study was to analyse the relationship between jumping and acceleration abilities in sprinters. Thirty-six sprinters from the national and international level took part in this study, completing Squat Jumps (SJ), Counter movement jumps (CMJ), and CMJ with progressive loads (CMJLoad), as well as 20m and 30m sprints. In this study, we obtained significant relationships between the CMJ (r=-0.65, p<0.01) and the CMJ with a load that generates the maximal power output in the CMJLoad test (r=-0.56, p<0.01), and the highest correlation was for the distance between 20m and 30m. In conclusion, time in shuttle distances (in this case the distance between 20m and 30m) would be the most reliable reference for verifying performance progression, and it would be advised that monitoring the changes introduced by speed training in the acceleration phase be conducted in a shuttle run distance. Furthermore, the load with which the maximum power output when jumping (CMJMP) is achieved should be used to monitor the progression of the athlete’s physical condition at any time during the training programme.
