Summary

The goal of this clinical trial is to learn if a micro-dosed plyometric training program works as well as a traditional plyometric program for improving speed and explosive abilities in elite under-19 soccer players during the pre-season. The main questions are: 1. Does micro-dosed training improve explosive and speed abilites, such as jumping and sprinting, as much as traditional training? 2. Does it improve reactivity and change-of-direction ability ? Researchers will compare two groups: * Traditional Training Group: 2 sessions per week, about 40 minutes each. * Micro-dosed Group: 3-4 shorter sessions per week, about 20 minutes each. Both groups will complete the same total weekly training volume. Participants will: * Take part in an 8-week plyometric training program during pre-season. * Complete performance tests (CM jump tests, a 30-meter sprint, and a 15-0-5 change-of-direction test, broad jump test, drop jump test) before and after 8-week plyometric intervention, . This study will help coaches and players understand if shorter, more frequent plyometric training sessions can be a good alternative to traditional longer sessions when weekly training load is matched.

Interventions

Type	Name	Description
BEHAVIORAL	Traditional group training program	This intervention consists of two supervised plyometric training sessions per week, each lasting about 40 minutes. It represents the traditional approach with fewer but longer sessions. The total weekly training volume is equivalent to the micro-dosed group but distributed differently.
BEHAVIORAL	Micro-dosed group training program	This intervention consists of three to four shorter supervised plyometric sessions per week, each lasting about 20 minutes. It represents a micro-dosed approach, with higher frequency but shorter duration per session. The total weekly training volume is equivalent to the traditional group but distributed across more frequent sessions.
