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).
Exploding out of the sprinting blocks requires coordinated movements from your hips, knees and ankles. The muscles that control extension of these joints produce the power that propels you forward and sends you down the track. As you push off the blocks, your ankles perform a movement known as plantarflexion.
