Question

Why are muscles in a non dominant arm expected to fatigue faster?

Answer 1

This arm fatigued faster because it because harder to recruit more muscle fibers in a short amount of time which causes the readings togo down.

Answer 2

Answer:

This arm fatigued faster because it because harder to recruit more muscle fibers in a short amount of time which causes the readings togo down.

Explanation:

The muscle returns to its original form during relaxation due to the formation of the cross ridge between the actin and the myosin filaments.

• Muscles help for the movement of the body by contraction and relaxation.
• Muscle contraction and relaxation occurs in a cycle which uses and reuses the same components.
• Contraction means getting shorter whereas relaxation means fibres slide apart and he muscle gets thinner and longer.
• Relaxation starts when the never stops to stimulate.
• Muscles have proteins which they use to relax and contract.
• Protein molecules in the muscles are used to relax the muscle cells in the body.
• Actin and myosin are the muscle proteins which help the muscles to contract and relax.

Actin and myosin are the muscle proteins which helps the muscle that helpreturn to its original form during relaxation after getting shortened due to contraction.#SPJ2
