relaxes and assists the agonist
- Agonist = Muscle producing the
desired action (prime mover)
- Antagonistic pair
- Antagonistic pair
- Examples
- Muscle Pairs
- 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
- E3 - all other muscles - generates speed - mechanical disadvantage
- most common
- 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
- 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
- EG = Upwards phase of
bicep curl/ press up etc
- Isotonic Eccentric = muscle required to control
movement by acting as a break, counteracting gravity
- Isometric = Contraction/ Tension of muscle causes no movement
- EG = Holding a balance in Gymnastics
- EG = Holding a balance in Gymnastics
- Isotonic = Contraction/ Tension
of the muscle causes movement
