An athlete suffers from muscular cramps while running a race. How can you help him overcome the cramps?

if an athlete suffers from a cramp we should help him by telling him to warm up. if u have seen any olympicks matches in tv u should have noticed that the athletes streaching therir legs  and arms to get warmed up.so they  do exercises like skipping and streaching to warm up and avoid these kind of cramps
 

we need to tell him to warm up before the the race by stretching hands and legs

when the athelete runs fast the body needs more energy ....so the muscles start working fast ......since the oxygen  required for producing energy is less so the muscles start to produce energy without oxygen ..thus they switch on to anaerobic respiration ....in this process lactic acid is produced as a by-product and gets accumulated in the muscles and so the muscle pains...hot water can help the muscles to get rid of the lactics acid
