What is the process called when a muscle shortens during contraction?

The process of a muscle shortening during contraction is known as concentric contraction. This type of muscle contraction occurs when the force generated by the muscle exceeds the external resistance, leading to the muscle fibers becoming shorter as they contract.

For example, when performing a bicep curl, as you lift the weight towards your shoulder, your bicep muscle shortens to create the upward movement.

Understanding concentric contractions is crucial in sports medicine as they contribute to movements that involve lifting or accelerating limbs, playing a significant role in strength training and rehabilitation exercises. This knowledge helps athletes and practitioners design effective workout programs that optimize muscle function and performance while reducing the risk of injury.
