Question: 1 / 430

What action is performed by supination of the hand?

Turning the palm downward

Turning the palm upward

Supination of the hand refers specifically to the action of turning the palm upward. This movement is an important aspect of forearm rotation and is commonly associated with movements that require the hand to be in a position to receive or hold objects, such as when you are holding a bowl or a cup.

In anatomical terms, supination occurs when the radius (one of the forearm bones) rotates around the ulna, resulting in the palm facing upward. This position is counter to pronation, where the palm faces downward.

Understanding supination is essential for trainers, as it plays a critical role in many exercises and daily activities. It can affect grip and the effectiveness of various weightlifting movements or functional tasks. Recognizing this can help trainers improve their clients' techniques to enhance performance and prevent injuries.
