What happens to your engine at the end of a long car trip? It doesn’t require a degree in automotive engineering to know that once you’ve reached your destination, your car’s engine stays warm as it gradually cools to a resting temperature.
The same thing happens to your body after exercise. Similar to how a car’s engine remains warm after being turned off, once a workout is over and you’re back in your daily routine, your body’s metabolism can continue to burn more calories then when at complete rest. This physiological effect is called excess post-exercise oxygen consumption, also known as the afterburn effect. The afterburn effect is the amount of oxygen required to restore your body to its normal, resting level of metabolic function (called homeostasis). It also explains how your body can continue to burn calories long after you’ve finished your workout.
HIIT workouts appear to be superior to steady state running or lower intensity circuit training in creating the afteburn effect. There is some debate about the significance of the afterburn effect for the average exercise participant because the high intensity exercise required can be extremely challenging.
However, if you want results and are up for the challenge, increasing the intensity of your workouts will be worth it.
So to get the best results from your workouts and to maximise the afterburn keep your heart rate above 85% of its maximum (or 9/10 on the RPE scale) during work intervals.
