Figure 1 shows an athlete in two different positions (A and B) as he performs a bicep curl.
Identify the joint action taking place at the elbow as the arm moves from A to B.
How to approach this question
Observe the change in the angle at the elbow joint as the athlete moves from position A (arm straight) to position B (arm bent). A decrease in the angle of a joint is known as flexion.
Full Answer
Flexion
In position A, the athlete's arm is extended at the elbow. In position B, the athlete has lifted the dumbbells, causing the angle at the elbow joint to decrease. The movement that decreases the angle of a joint is called flexion.
Common mistakes
Confusing flexion with extension.
