Muscle injuries are very common in both professional and recreational athletes. They typically occur in muscles that cross two joints, during explosive activities such as sprinting, and when the athlete is suddenly increasing their exercise regimen (i.e., training camp).
Sprinting is a combination of acceleration, power, speed and technique. When you sprint, the fast twitch fibers in your muscles fire quickly and powerfully to drive explosive movement.
