Which of the following factors helps promote growth and recovery after training and competition?

Promoting growth and recovery after training and competition involves several key factors, and reducing fatigue is particularly important in this context. Fatigue, whether physical or mental, can hamper an athlete's ability to recover effectively. When athletes experience fatigue, their muscles may need more time to recover, and their overall performance can decline.

By focusing on reducing fatigue, athletes are likely to enhance their recovery processes. This includes mechanisms like muscle repair, replenishment of energy stores, and mental recovery, all of which are critical for optimal performance in future training sessions or competitions. Proper management of fatigue can lead to better adaptation to training loads, ultimately contributing to improved athletic performance and growth.

While hydration and carbohydrate intake are also significant for recovery, and cognitive performance plays a role in overall athletic ability, they do not directly address the immediate impact of fatigue in the same way as focusing on its reduction.
