​

Answer 1

Explanation:

so while playing our muscles activate and some people have cramps so rubbing will help to get our body in a normal way

Answer 2

During extensive physical activity as in track and field events our muscles require more energy, which cannot be supplied by normal respiration. Due to insufficient supply of oxygen, anaerobic respiration occurs and lactic acid is formed.

Collection of this lactic acid in his muscles, made Rajat suffer from cramps after participating in sports.

Robbing the muscles slowly, would supply oxygen to Rajat's muscle cells by blood circulation, which would break down the the lactic acid and ease the pain caused by the cramps.

Hope this helps
