Dehydration, most commonly
You can get a twitch from stimulation or damage to the muscles.
There are fast twitch muscles fibers in all of your muscles, especially in your legs.
Yes, slow twitch muscles generally have a higher concentration of mitochondria compared to fast twitch muscles. Mitochondria are responsible for producing energy in cells, and slow twitch muscles require more energy for sustained, endurance activities.
Slow twitch
when muscles twitch
fast-twitch NOT slow-twitch
because it makes you react quickly by using fast twitch fibres in your body which makes your muscles react.
Well, I'm not completely sure of this, but in my science class we were talking about slow- twitch muscles (like your esophagus for example) and fast twitch muscles (like your leg muscles). Anyway, I asked do sloths have slow twitch muscles in their legs, and he said to look it up, so I did, and it turns out they do! So the reason is they have slow twitch gastrocnemus (calf) muscles!
Cheetahs have mostly fast-twitch muscles, which allow them to achieve high speeds in short bursts during hunting. These muscles facilitate rapid acceleration and swift movements, making cheetahs the fastest land animals.
Activities that involve quick, explosive movements like sprinting, jumping, or weightlifting are ideal for fast-twitch muscles.
probably, because your muscles twitch because they don't know what to do but twitch. not for long though.
Slow-twitch
