  • Types of contraction
    • isotonic contraction
      • the muscle changes length
      • two types
        • concentric contraction
          • the muscle shortens to create the movement
          • >e.g. bicep curl
            • the bicep is contracting - making the movement
        • eccentric contraction
          • the muscle lengthens to create the movement
          • >e.g. the downwards phase of a push-up
            • the tricep is lengthening to control the movement
    • isometric
      • the muscles stays the same length
      • >e.g wall sit
        • the quadriceps and the hamstrings stay the same length
      • >e.g. crucifix in gymnastics
        • the arm muscle are contracting to keep them up in the position
