Effect of Plyometric Exercise on Stability in Professional Indoor Soccer Players: A Pilot Study

Study Overview
=================
Brief Summary
-----------------
A program is proposed for two groups of professional indoor soccer players where the effect of plyometric exercises on body stability will be evaluated on a stabilometric platform.

Detailed Description
-----------------
A program is proposed for two groups of professional indoor soccer players where the effect of plyometric exercises on body stability will be evaluated on a stabilometric platform. Four evaluations will be carried out. An initial measurement before the beginning of the first intervention phase (Visit 1), after the intervention (Visit 2; day 30), after a 15-day washout period (Visit 3; day 45) and after the second intervention phase (Visit 4; day 75).
