Detailed explanation-1: -The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy.
Detailed explanation-2: -Adenosine triphosphate (ATP) is the sole fuel for muscle contraction. During near maximal intense exercise the muscle store of ATP will be depleted in < 1s, therefore, to maintain normal contractile function ATP must be continually resynthesized.
Detailed explanation-3: -The main types of “fuel” used by muscle for energy metabolism are glycogen, glucose, and free fatty acids [1-3]. The particular energy sources used by working muscle for aerobic metabolism depend upon a number of factors including the intensity, type, and duration of exercise, physical conditioning, and diet [4-6]:
