Question

give reasons
we feel exhausted after exercising ​

Answer 1

Answer:

We get tired after exercise because our muscle fibers get tired very quickly. This is due to the major source of energy for the muscle tissue, called adenosine triphosphate, or ATP. As the muscles make use of this supply of energy, they get tired and fatigue.

Answer 2

Allo !!!

• When we perform exercises constantly, there maybe shortage of oxygen in the the cells and therefore our muscles and other tissues perform anaerobic respiration.

• In this process lactic acid is formed (lack of O2 leads in the conversion of Glucose into lactic acid)

• Thus due to the accumulation of lactic acid (loss of energy in the muscles) we feel pain and fatigue.
