Slow twitched fibers. The slow muscles are more efficient at using oxygen to generate more fuel (known as ATP) for continueous, extended muscle contractions over a long period, eg long endurance athletes, triathlon, marathon,...
Slow-twitch muscle fibers are used for low-intensity endurance.

Long distance running helps your body burn calories, build muscle, and increase overall fitness. It does cause additional strain to the legs and joins.
weight lifting uses white muscle. Red muscle is used for longer sustained, repetitive movements, like long distance running.
You can always use any kind of running. it really doesn't matter if you're a sprinter or not. Any running will help build muscle.
Generally the cause of cramp is not having enough salt in your diet.
You can make your thighs and legs skinner without gaining any muscle by running long distance
Type I (red) muscle fibers, which have slow oxidative characteristics, are those primarily called on for long-distance running. These are more commonly referred to as 'slow-twitch' muscle fibers.
It is not the muscle but the muscle fiber which works for when recruited for long duration. The red muscle fiber or the slow twitch fiber gets recruited for long term stress on the muscle for example if you do bench press on heavy weight explosively for 5 reps you extensively use fast twitch fibers but if you do bench flys for 15 reps in controlled fashion, you extensively use red fibers.
Running will not be enough to build muscle. If increased muscle mass is your goal, incorporate sprint and muscle training.
Muscle cells are called muscle fibers because of their long, slender shape that resembles a fiber. The structure of muscle cells allows them to contract and generate force, which is essential for muscle function. The term "fiber" is used to describe the long, cylindrical shape of these cells that run parallel to each other in muscle tissue.
