Which muscle group is primarily solicited during the Arm Curl test?

The Arm Curl test primarily targets the biceps muscle group. This test is designed to assess upper body strength and specifically measures the strength of the arm flexors, which include the biceps brachii. During the test, participants perform curls by lifting a weight towards their shoulder, a motion that involves significant activation of the biceps as they contract to bend the elbow and lift the weight.

While other muscle groups, such as the triceps or shoulders, may be involved in the movement, they do not play the primary role in the action of curling the weight. The focus is on the biceps, which work specifically to lift and flex the arm, making them the key muscle group being evaluated in this particular test. Understanding this relationship between the exercise and the targeted muscle group helps emphasize the importance of bicep strength in overall upper body functionality, especially in older adults.
