Wrist Curl (Wrist Flexion)

Major Muscles and Actions Involved

Wrist Curl (Wrist Flexion)The flexor carpi ulnaris and the flexor carpi radialis muscles are involved in wrist joint flexion. In this action the palm side of the hand moves toward the forearm. 

Sports Uses

Wrist joint flexion and the muscles involved are most important in almost all sports that require throwing actions. The sports include baseball, football, team handball, softball, javelin, and basketball. In the field events in track, wrist joint flexion is essential in the shot put and javelin throw. It is also very important in hitting actions such as the tennis, badminton and racquetball flat serves, smashes, and forehands, the volleyball spike, ice and field hockey hits and “throws” as in lacrosse. 

Did you know...

  • The flexor carpi radialis and ulnaris muscles cross both the wrist and elbow joints, and therefore have an action at each end. Because of this, in order to get a strong contraction at the wrist, your elbow must be firmly stabilized. It is also effective to stretch and tense the muscles at the elbow joint by straightening your arms. When the elbow is extended, the flexor muscle tendons become taut at the upper end.
