Detailed explanation-1: -Exercise, especially strength-based training, forces our muscles fibres to contract and stretch repeatedly. This causes tiny tears in the fabric of the muscle, the size of which depends on the intensity of the exercise. This causes the feeling of muscle soreness you might be familiar with the day after exercise.
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: -High-intensity exercise can result in up to a 1, 000-fold increase in the rate of ATP demand compared to that at rest (Newsholme et al., 1983). To sustain muscle contraction, ATP needs to be regenerated at a rate complementary to ATP demand.
