1.Movement Analysis

1. Muscles!

   • Muscle Pairs
     • Examples
       • Quads & Hamstrings
       • Bicep & Tricep
       • Trapizius & Pectorals
     • Antagonist = Muscle that relaxes and assists the agonist
     • Agonist = Muscle producing the desired action (prime mover)
       • Antagonistic pair

2. Lever Systems

   • E3 - all other muscles - generates speed - mechanical disadvantage - most common
   • R2 - ankle - overcome heavy loads - mechanical advantage
   • F1 - tricep - generates speed & overcome heavy loads

3. Muscle Contractions

   • Isotonic = Contraction/ Tension of the muscle causes movement
     • Isotonic Eccentric = muscle required to control movement by acting as a break, counteracting gravity
       • EG = Downwards phase of bicep curl/ press up etc
     • Isotonic Concentric = muscle will shorten and fatten as it contracts
       • EG = Upwards phase of bicep curl/ press up etc
   • Isometric = Contraction/ Tension of muscle causes no movement
     • EG = Holding a balance in Gymnastics
