Summary

This study aims to investigate the differential effects of three training protocols: traditional Yo-Yo intermittent training, ball-dribbled Yo-Yo intermittent training, and small-sided games (SSGs) on aerobic capacity, anaerobic and exercise enjoyment in adolescent soccer players.

Conditions

• Soccer Training
• Aerobic Capacity
• Anaerobic Power
• Physical Activity Enjoyment

Interventions

Type	Name	Description
OTHER	Yo-Yo running training	Yo-Yo running training is a form of running-based high-intensity interval training characterized by repeated bouts of shuttle running with intermittent recovery periods. The training involves forward and backward running over a fixed distance at progressively increasing speeds, following standardized Yo-Yo test protocols.
OTHER	Ball-dribbled Yo-Yo training	Ball-dribbled Yo-Yo training is a modified form of Yo-Yo-based running training that integrates ball dribbling into an intermittent shuttle running format. This intervention combines repeated high-intensity running bouts with soccer-specific technical demands, requiring participants to control and dribble a ball while performing forward and backward shuttle runs at prescribed speeds.
OTHER	Small-sided games	Small-sided games (SSG) are a game-based soccer training intervention characterized by modified match play involving a reduced number of players on a smaller pitch. This intervention requires participants to engage in intermittent, high-intensity activities while performing soccer-specific technical and tactical actions under game-like conditions.
