  1. Muscle Contractions & Exercise

  2. Types of Muscle Contractions Concentric (shortening): when muscle fibers shorten Eccentric (lengthening): when muscle fibres lengthen Isometric (static): when muscles fibres don’t change length

  3. Muscle Contraction & Exercise Isotonic Exercise: involves a controlled shortening and lengthening of the muscle. ex. weight training with dumbbells & free body weight exercises

  4. Muscle Contraction & Exercise Isometric Exercise: when the muscles fibres maintain a constant length throughout the entire contraction and there is no motion • Used for rehabilitation exercises • Quick and convenient method for strengthening muscles without special equipment • Little chance of injury

  5. Muscle Contraction & Exercise Isokinetic Exercise: the use of machines to control the speed of contractions within the range of a muscle’s motion • Combines isotonic & isometric • Allows force to be exerted at a constant and pre-set speed through the full ROM
