Explanation:
The pain in her legs could be because of the accumulation of lactic acid in
the muscles. During heavy exercise or running, etc., the muscle cells respire anaerobically and produce lactic acid.
The massage gave her reliefbecause it improves the circulation of blood leading to increased supply of oxygen to the muscle cells which helps in complete breakdown of lactic acid into CO, and water.
