Energy balance also has to do with whatâs going on in your cells. When youâre in a positive energy balance (more in than out) and when youâre in a negative energy balance (more out than in), everything from your metabolism, to your hormonal balance, to your mood is impacted.
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).
Cramps tend to occur when runners run farther or faster than they are used to and occur more often in muscles that cross more than one joint, such as the gastrocnemius muscle in the calf (which crosses the ankle and knee) and the biceps femoris (one of the hamstring muscles, which crosses the hip and knee).f you get a side stitch while running on trails, slow your pace a little and take some deep, even breaths. Try bending forward while tightening your abdominal muscles and massage the area with your fingers. For muscle cramps, stop and passively stretch the muscle.
