Detailed explanation-1: -In volleyball just like most sports, an eccentric muscle contractions (lengthening of muscles) is followed by concentric muscle contractions (shortening of muscles).
Detailed explanation-2: -Eccentric contraction occurs when the total length of the muscle increases as tension is produced. For example, the lowering phase of a biceps curl constitutes an eccentric contraction.
Detailed explanation-3: -Concentric Contractions A concentric contraction is a type of muscle contraction in which the muscles shorten while generating force, overcoming resistance. For example, when lifting a heavy weight, a concentric contraction of the biceps would cause the arm to bend at the elbow, lifting the weight towards the shoulder.
