MUSCLE PHYSIOLOGY

Detailed explanation-1: -Isometric exercises are tightening (contractions) of a specific muscle or group of muscles. During isometric exercises, the muscle doesn’t noticeably change length. The affected joint also doesn’t move.

Detailed explanation-2: -Isometric exercises are exercises that involve the contraction of muscles without any movement in the surrounding joints. The constant tension on the muscles may help improve muscle endurance and support dynamic exercises.

Detailed explanation-3: -Isometric contraction: A muscle contracts, but the joint it controls does not move. Think of holding a weight with your elbow bent to 90 degrees and does not move. Isotonic contraction: A muscle contracts and the joint angle it controls increases and decreases while the muscle either shortens or lengthens.
