Interval training enhances endurance in youth soccer

In young soccer players, the amount of field time can be tiresome. By increasing their endurance they can perform better on the field. A recent study measured the endurance of youth soccer players before and after a 10 week training program that incorporated intervals and high intensity aerobic exercise.
The intervals consisted of four bouts of 4 minute work periods, dribbling a soccer ball through a specific course. Each period was separated by a 3 minute jog. This was performed twice weekly at the conclusion of regular soccer training. It began 6 weeks before competition and continued for 4 weeks into the season. At the conclusion, sprinting and jumping ability were not affected. By utilizing specific techniques in preparation for competition, young soccer players can build endurance and enhance their skills during games.
