Question: How does a footballer run during a match

Marlene Lorgen answered on 10 Nov 2013:

Football players are constantly training to increase what is called stamina, the ability to keep on going. Training helps to build up muscle and make the lungs and heart stronger, which allows them to supply more oxygen to the muscles to keep them from getting tired. Professional players like Wayne Rooney can cover as much as 10km ( 6 miles) in ine match!
