1.Movement Analysis
  1. Muscles!
    1. Muscle Pairs
      1. Examples
        1. Quads & Hamstrings
          1. Bicep & Tricep
            1. Trapizius & Pectorals
            2. Antagonist = Muscle that relaxes and assists the agonist
              1. Agonist = Muscle producing the desired action (prime mover)
                1. Antagonistic pair
            3. Lever Systems
              1. E3 - all other muscles - generates speed - mechanical disadvantage - most common
                1. R2 - ankle - overcome heavy loads - mechanical advantage
                  1. F1 - tricep - generates speed & overcome heavy loads
                  2. Muscle Contractions
                    1. Isotonic = Contraction/ Tension of the muscle causes movement
                      1. Isotonic Eccentric = muscle required to control movement by acting as a break, counteracting gravity
                        1. EG = Downwards phase of bicep curl/ press up etc
                        2. Isotonic Concentric = muscle will shorten and fatten as it contracts
                          1. EG = Upwards phase of bicep curl/ press up etc
                        3. Isometric = Contraction/ Tension of muscle causes no movement
                          1. EG = Holding a balance in Gymnastics
