What is the effect of fatigued muscles on their performance after recovery?

The correct answer is that fatigued muscles, after a proper recovery period, can respond by becoming stronger and more capable. This phenomenon is associated with the principle of supercompensation, which occurs when muscles experience stress, such as during intense exercise, leading to fatigue. When they recover, they rebuild not only to their previous strength but often exceed it, as the body adapts to better handle similar stress in the future.

This adaptive response is a key concept in strength training and endurance sports, as muscles need time to repair and strengthen during recovery. When properly managed, this training cycle enhances overall performance, allowing individuals to lift heavier weights, endure longer exercise sessions, or improve their speed and agility after periods of rest.

Understanding this principle highlights the importance of incorporating rest and recovery into any training program. It emphasizes that while fatigue can temporarily diminish performance, adequate recovery and nourishment can lead to improved capability and strength over time.
