Purpose:
This study aimed to analyse the relationship between vertical jump parameters – jump height (JH), peak power output (PPO), and mean power output (MPO) – and specific physical performance in different sports using the allometric approach. In this sense, it was verified whether scaled power output for body mass might have a stronger correlation with physical performance than raw power output.

Methods:
The study involved 52 male athletes (21 judokas, 18 futsal players, and 13 sprint runners). They performed the following tests: vertical jumps (countermovement and squat), specific physical tests for judo (Special Judo Fitness Test), repeated sprint ability for futsal players, and sprint running (20 m and 200 m) for runners. A specific allometric exponent for PPO and MPO was established. Pearson’s correlation was used to determine the relationship between physical tests and vertical jump parameters for absolute and allometric scales.

Results:
Moderate to very large correlations were found between physical performance and JH (r: 0.47–0.87), PPO (r: 0.47–0.75), and MPO (r: 0.49–0.81). Considering power output scaled for body mass, the correlation between jump parameters and physical performance was greater than absolute values, in which the r values ranged 0.46–0.81 for PPO and 0.52–0.84 for MPO.

Conclusions:
JH and power output seem to correlate in a similar magnitude with physical performance tests for most variables and sports analysed. From a practical point of view, coaches and physical trainers are encouraged to use JH to monitor training, considering the cost of equipment and practicality.
