Expert Answer
- When you run after several days, there is a strain on your muscles.
- The demand for energy is high, but the supply of oxygen to produce the energy is limited.
- Then anaerobic respiration takes places in the muscle cells to fulfil the demand of energy.
- The cramps occur when muscle cells respire anaerobically.
- The partial breakdown of glucose produces lactic acid.
- The accumulation of lactic acid causes muscle cramps.
- We get relief from cramps after a hot water bath or a massage. Hot water bath or massage improves circulation of blood.
- As a result, the supply of oxygen to the muscle cells increases. The increase in the supply of oxygen results in the complete breakdown of lactic acid into carbon dioxide and water.
