MUSCLE PHYSIOLOGY

Detailed explanation-1: -Isometric contractions: The type of skeletal muscle contractions in which the length of the muscle remains constant but the pressure is increased. Example: Pushing against the wall.

Detailed explanation-2: -Isometric contraction occurs when muscle length remains relatively constant as tension is produced. For example, during a biceps curl, holding the dumbbell in a constant/static position rather than actively raising or lowering it is an example of isometric contraction.

Detailed explanation-3: -Pushing against a wall involves the muscle contracting in a way that doesn’t change the muscle’s length. This is known as an isometric contraction.

Detailed explanation-4: -What is an example of isotonic contraction? Isotonic exercises are any where the length of a muscle changes. Examples include bicep burls, push-ups, pull-ups, and contractions occurring in the legs while running.

Detailed explanation-5: -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.
