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).
Rest the muscle. When you strain a muscle, stop doing the activity that caused it to be strained. Pulled muscles are actually rips in muscle fibers, and further exertion could cause the tear to grow larger and lead to a serious injury. Let the amount of pain you feel be your guide. If a pulled muscle occurs while you're running or playing a sport, and you have to stop and catch your breath due to the severe pain, the best thing to do is sit the rest of the game out.
