Which muscle contraction occurs when the muscle lengthens under tension?
|
|
Isokinetic
|
|
|
Isometric
|
|
|
Eccentric
|
|
|
Concentric
|
Explanation:
Detailed explanation-1: -There are 2 types of isotonic contractions: concentric and eccentric . In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.
Detailed explanation-2: -Eccentric Muscle Contraction Extending your elbow during a bicep curl and lowering the forearm away from the shoulder is a eccentric contraction for the bicep muscles.
Detailed explanation-3: -Eccentric contractions cause muscles to elongate in response to a greater opposing force. Isometric contractions generate force without changing the length of the muscle.
