MUSCLE PHYSIOLOGY

Detailed explanation-1: -Riding a stationary bike, raising a dumbbell with a bicep curl, and holding a weight at a constant height are examples of isokinetic, isotonic, and isometric contractions, respectively.

Detailed explanation-2: -Concentric contractions occur when the muscles shorten while generating force. An example of concentric contraction would be the upward pull during a pull up. Eccentric contractions occur when the muscles lengthen while generating force.

Detailed explanation-3: -What are some forms of isotonic exercise? Aerobic exercises like walking, running, hiking, swimming, skiing, and dancing are all considered isotonic exercise. So are resistance training exercises that involve movement, such as squats, pushups, pull ups, bench presses, deadlifts, and bicep curls.

Detailed explanation-4: -Isometric: A muscular contraction in which the length of the muscle does not change. isotonic: A muscular contraction in which the length of the muscle changes. eccentric: An isotonic contraction where the muscle lengthens. concentric: An isotonic contraction where the muscle shortens.
