Webb20 dec. 2024 · Muscle fibers use two filaments (actin and myosin) to produce movement: a myosin grabs actin and pulls it towards the midline, thus shortening and stacking filaments (see sliding filament theory ). We call this a muscle contraction (or “twitch”). The faster this occurs, the fast the muscle contracts, the faster you move. Webb4 nov. 2024 · Dietary fiber — found mainly in fruits, vegetables, whole grains and legumes — is probably best known for its ability to prevent or relieve constipation.
