The Afterburn Effect
1Finalround HIIT workouts create an afterburn effect, but why is that important?
Oxygen deficit and compensation is a physiological effect that results in your body continuing to burn extra energy for up to 2 hours after a workout.
Your body uses oxygen to generate energy. The harder you workout the more oxygen you need. Our HIIT workouts cause a large increase for a short period of time in all your vitals; pulse, respiratory rate, body temperature and metabolism.
The magic of EPOC aka the oxygen debt
Within a few minutes of starting a 1FinalRound workout your body will take in as much oxygen as it needs, however, as your breathing gets heavier and you get short of breathe your body begins to run an oxygen deficit or debt. Like all debts this must be repaid. After your workout your body will begin to repay this debt with interest by absorbing more oxygen then is actually needed to repay the debt.
Additionally the body will attempt to return to its resting state of before the workout. In order to do this it will need to replenish fuel stores, rebalance hormones, conduct cellular repair and replenish the phosphagen system. All of these process require energy a large amount of energy to be used which contributes to the afterburn effect.
How long will the afterburn last?
Everyone is different but the harder the workout the longer the body will need to return to its pre workout state. Studies have shown the afterburn effect generally reaches its peak during the first hour after exercise before decreasing.
What does all this mean?
The effects from the afterburn effect vary from person to person but your body may burn an additional 20% of the energy consumed during the workout. It might not sound like much, but the extra 20% adds up over time. No other workout type promotes the afterburn effect as effectively as HIIT, making it ideal for weight loss.
