Name the three types of muscle contractions in biomechanics.

The correct answer identifies the three types of muscle contractions commonly recognized in biomechanics: isometric, concentric, and eccentric contractions.

Isometric contractions occur when a muscle generates force without changing length, meaning that the muscle maintains a constant position against resistance. This type of contraction is important for stabilization and maintaining posture.

Concentric contractions involve the muscle shortening while producing tension; for example, during the upward phase of a bicep curl, the biceps shorten as it lifts the weight. This type of contraction is how muscles typically work to produce movement.

Eccentric contractions, on the other hand, occur when a muscle lengthens while under tension. This often happens when controlling movements, such as lowering a weight back down after a lift, and plays a crucial role in activities that require deceleration and control.

In contrast, the other provided options contain terms or combinations that do not accurately reflect the conventional classifications used to describe how muscles contract during physical activity.
