Congested Fixtures: The Survival Guide
Recovering between games can be challenging, even for professional footballers. During a three game week, players typically have 48 hours of recovery between games. That means physical stress on the body is far greater, increasing the risk of injury and illness.
Amateur players can often face the same challenges at the end of a season as they’re faced with a bottleneck of fixtures as a result of winter postponements. Find out how SiS football supplements can help you to navigate your way through your congested fixture schedule from our experts.
