Agility, an essential aspect of various sports, has attracted increasing interest and has become a popular subject of research due to its direct influence on athletic performance.

Aim of the Study:
The aim of this study was to analyze an acute effect of training with VertiMax and inertial devices as mechanisms for post-activation performance enhancement (PAPE) in physically active individuals.

Material and Methods:
A sample consisted of 27 participants with an average age of 24.33 ± 2.89 years. Participants were randomly assigned to three groups: An inertial RSP-squat device group, a VertiMax device group, and a control group.

Frequentist analyses revealed a significant interaction between pretest and posttest conditions, although no significant differences were found between the study groups. These findings were confirmed by Bayesian analyses. Both experimental groups and the control group showed reductions in race times, although a percentage of change was higher for a VertiMax training protocol. Additionally, it was observed that rest periods of approximately five minutes between measurements were more effective in improving athletic performance.

Integration of PAPE-based training strategies with the use of devices can be crucial in optimizing athletic performance, although ongoing research is needed to inform practical and theoretical decisions in a field of physical conditioning
