3. Muscle Fiber Types: Fast Twitch Muscle Fiber and Slow Twitch Muscle Fiber
1. Slow Twitch
Muscles that are associated with aerobic work are called slow twitch. These are the muscles
working when we do the simpler yoga poses. Small force is produced over a sustained
period. It is suited for endurance activities such as running marathons.
2. Fast Twitch
These fibres are associated with anaerobic activity. They are used when we perform high
intensity activity which is sustained for shorter periods such as sprinting. The lactic acid
build up from these activities means they cannot be sustained for a long time.

4. Muscle Fiber Types: Fast Twitch Muscle Fiber and Slow Twitch Muscle Fiber
1) Fast oxidative glycolytic fibres
These are more resistant to fatigue that fast glycolytic fibres.
2) Fast glycolytic fibres
These fibres generate the largest amount of force and have the greatest anaerobic capacity.
