Professional football and soccer players run 11 kilometers (7 miles) every game on average. Professional football and soccer games are 90 minutes long, therefore (90 minutes) / (11 kilometers) = 8.18 minutes per kilometer. If you are a defender, midfielder, or forward, you will run between 5 and 11 kilometers over the whole game. A professional player covers about 7 miles every game. In addition to running, soccer players may be asked to jump, chase down balls, and make intense use of their muscles during games. All of this requires a great deal of energy! The average professional soccer player consumes about 3,500 calories per day during a season. That's about 200 calories more than the average person. In conclusion, professional soccer players must put in a lot of effort to succeed in their sport. They need to be strong, fast, and fit to play at a high level. Also, they must have a lot of courage because there will be times when they will be injured and unable to play. There are also risks involved with playing sports professionally. For example, if you are a baseball player you could suffer from arm pain due to all the throwing that is required of pitchers and fielders. In addition, soccer players risk injury when kicking balls during play or when making contact with opponents. There are also dangers associated with playing sports at a young age; for example, if you are a basketball player and you do not develop proper body control you could seriously injure yourself.
