Key Points

List 1	List 2
Muscle Contraction of the ankle joint in the downward phase	Eccentric: It is a phase of muscle contraction. It occurs when a force applied to the muscles exceeds the momentary force produced by the muscles. It results in the lengthening of the muscle. It occurs when the total length of muscle increases as tension is produced.
Muscle Contraction of the shoulder joint in the downward phase	Concentric: It is a phase of muscle contraction. It occurs when the total length of the muscle shortens as tension is produced. The upward phase of the biceps curl is a concentric contraction.
Active muscle group of the knee in the downward phase	Extensors: Extensors are the active muscles group that helps to do extension movements. The extension is the movements in which joint angles are increased. For example: in elbow extension, the triceps acts as extensors.
Active muscle group of the shoulder in the upward phase	Flexors: Flexors are the active muscle group that helps to perform flexion. Flexion is the movement in which the joints' angle decreases. For example: In elbow flexion, the biceps acts as flexors.
