Effectiveness of a Home-based Telehealth Exercise Program on Adherence and Performance in Handball Players

The objective of this clinical trial is to determine whether Physitrack®, a telerehabilitation platform, improves players\' adherence to exercise programs. The secondary objectives are to assess whether its use enhances players\' jumping ability (speed, height, flight time) and to evaluate the usability of the Physitrack® application from the players\' perspective, considering aspects such as ease of use and user satisfaction. The main questions this study aims to answer are: Do exercise programs conducted through an online telemedicine platform achieve good adherence among handball players? Do exercise programs carried out via this telerehabilitation platform improve performance in vertical jumping? Do exercise programs performed using this platform provide good usability and user satisfaction results? To answer these questions, researchers will compare two groups following different exercise programs. The study will analyze whether, in addition to improving adherence, a specific program designed to enhance vertical jumping yields better results compared to a more general exercise program. Participants: Will perform a vertical jump test using force plates. Must follow the assigned eight-week exercise program according to randomization. Will repeat the vertical jump test at the end of the program.
