What is an atagonistic pair
Muscles that work together to create a movement
This happens when a muscle contracts
1 muscle is the agonist,1 is the antagonist
Muscle fibre (type 1)
-suit endurance activities-can work for long periods of timw
-darker in colour because they contain myoglobin,a red pigment that transports oxygen to working muscles.
Fast twitch(type IIa)
Type a-used in anaerobic work which can be improved through high intensity interval training.Increasing their resistance to fatigue
