Slow twitch
There are two types of muscle fibers, fast-twitch and slow-twitch. Each muscle is a combination of different proportions of these fibers. Muscles in different people have different compositions, which is why some athletes are better marathon runners, while others are better sprinters.
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.
fast-twitch NOT slow-twitch
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.
People who possess a high percentage of fast twitch muscles will generally be quicker, faster, and able to jump higher than people with a lower percentage of fast twitch muscles.
Fast-twitch fibers can deliver a quick burst of power.Slow-twitch fibers can maintain a contraction for a longer time! -Apex :]
yes
They contract very quickly
Fast twitch muscles contract quickly and are used for explosive movements, while slow twitch muscles contract more slowly and are used for endurance activities. Athletes with a higher proportion of fast twitch muscles may excel in activities requiring quick bursts of power, such as sprinting or weightlifting, while those with more slow twitch muscles may perform better in endurance activities like long-distance running or cycling. The ratio of fast to slow twitch muscles can impact an athlete's performance in different sports based on the specific demands of the activity.
