Excessive Post-Exercise Oxygen Consumption, also know as the After Burn. When we complete an intense and strenuous workout we challenge our anaerobic threshold. This mean the ability to output energy with none or little oxygen. When we use energy like this we create a debt in oxygen. When we do this the body post workout needs to repay the debt to return to it's beloved steady state. During this transition the body requires oxygen to restore hormone, metabolic function and cellular repair. The body uses it's stored energy like fatty acid to complete this transition. A more oxidative system, as oxygen needs to be present to reset the body and recover.
Therefore, when your thinking how this effects your results it is simple. Our body can only truly be pushed in anaerobic threshold for short burst of intensities. So, keeping workouts short but sassy will stimulate E.P.O.C. Combined with the right effort to create greater debts of oxygen. Taking more energy and time to repay. More fat used and more calories burned. The "after burn" it can take up to 36 hours to establish it's steady state post workout.
How do you create E.P.O.C. effectively? Using more Metabolic Driven programs can condition this in time efficient, yet effective way. I am a fan of incorporating this type of conditioning into my programs. Both for clients and personally. They are adaptable and effective. I do believe we need to balance it out. Because creating that type of stress everyday on the body can have it's down falls. However, this is one of my favourite and most effective conditioning practice that I have seen in my career for weightloss and performance.
