1. The differences between isotonic, isometric, concentric, and eccentric contractions. 2. The factors that determine isotonic and isometric contractions. Introduction: The muscle fibers shorten in order to contract and produce a movement in the body. The contraction of skeletal muscles takes place by sliding of actin filaments over myosin filaments or by the cross-bridge formation between them. This results in shortening of the muscle length.
