Question
Why we get muscle cramps after heavy exercise?
✓
Answer
During heavy exercise the demand for energy is high. But the supply of oxygen to produce energy is limited. Then anaerobic respiration takes place in the muscle cells to fulfil the demand of energy. Glucose in absence of oxygen → Lactic Acid + Energy. The cramps occur only when the muscle cells respire anaerobically. The partial breakdown of glucose produces lactic acid. The accumulation of lactic acid causes muscle cramps.
