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).
If a runner doesnât follow instructions, they can suffer from a recurrent hamstring tear that can lead to a permanently injured muscle that never provides full function again. As a precaution, Dr. Post advises athletes to have a trusted source to turn to before an injury occurs.
