1.	What is fast twitch muscle fibre and slow twitch muscle fibre??
Answer» Plzz explain it in simple words...<br>Your body has two types of skeletal muscle fibers: slow-twitch (type I) and fast-twitch (type II).Slow-twitch muscles give you the stamina to nail endurance tasks like distance running. People use fast-twitch muscles in explosive actions, like sprinting, jumping, or playing a cameo in a “Fast and Furious” movie. (If you have furious-twitch muscle fibers, seek medical assistance.)During aerobic exercises like running or swimming, slow-twitch fibers are the first to contract. But when you’re throwing around heavy kettlebells or playing a sport, you’re using fast-twitch muscles.
