The human body has mainly two types of muscle fibres: slow-twitch and fast-twitch.  The { slow or fast} twitch  contract slowly and resist fatigue and produce most of their energy through { aerobic or anaerobis} rispiration. These muscle fibres are best used for activities like { weight lifting and playing tennis or biking and jogging} The { slow or fast} twitch  are adapted for the rapid regeneration of power. They can best be used in activities such as { weight lifting and playing tennis or biking and jogging}. They are rich in glycogen and depend on { aerobic or anaerobis} rispiration.  to produce energy. This leaves them vulnerable to the accumulation of lactate and they fatigue quickly. which one are those? the answers

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.
