Sponsor's own description
This study explores how different small-sided football games affect players' heart and technical skills. We will compare two ways of playing: "Free Play," where players act freely, and "Controlled Pass," where passing rules are used. Elite football players will participate in both types of games on small fields (3 vs 3 and 4 vs 4). We will measure heart responses (like heart rate) and how often players touch the ball. The goal is to help coaches choose the best game format to improve fitness and technical ability in training.
