MICROANATOMY

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: -In a concentric contraction, the force generated by the muscle is less than the muscle’s maximum, and the muscle begins to shorten. This type of contraction is widely known as muscle contraction. It requires more energy compared to the other two types, but this contraction generates the least force.

Detailed explanation-3: -Muscle contracture refers to physical shortening of muscle length, and it is often accompanied by physical shortening of other soft tissues such as fascia, nerves, blood vessels, and skin.

Detailed explanation-4: -Concentric Contractions This occurs throughout the length of the muscle, generating force at the musculo-tendinous junction; causing the muscle to shorten and the angle of the joint to change.
