This physiological effect is called excess post-exercise oxygen consumption, or EPOC. Also known as oxygen debt, EPOC is the amount of oxygen required to restore your body to its normal, resting level of metabolic function (called homeostasis).
What is EPOC used for?
In recovery, oxygen (EPOC) is used in the processes that restore the body to a resting state and adapt it to the exercise just performed. These include: hormone balancing, replenishment of fuel stores, cellular repair, innervation, and anabolism. Post-exercise oxygen consumption replenishes the phosphagen system.
What is an example of EPOC?
For example, if you did three workouts a week that had an average EPOC effect of 100 calories per workout, you’d be burning an extra 300 calories beyond what you burned during your workouts!
What exercise causes EPOC?
The key to inducing significant EPOC is to partake in high-intensity interval training, or HIIT. These short rounds of intense work are broken up with equally short recovery periods.
How does EPOC burn fat?
You need to up the intensity, but in a highly specific way. EPOC increases your body’s oxygen intake to redress its deficit, balance your hormones, replenish fuel stores and repair cells – all of which requires extra energy and, you guessed it, burns through more calories.
What is EPOC for weight loss?
EPOC (the Afterburn Effect) Defined
EPOC refers to the elevation in metabolism (rate that calories are burned) after an exercise session ends. The increased metabolism is linked to increased consumption of oxygen, which is required to help the body restore and return to its pre-exercise state.
Does HIIT change your metabolism?
Some researchers have even found that HIIT increases your metabolism after exercise more so than jogging or weight training ( 10 ). The same study also found that HIIT could shift the body’s metabolism toward using fat for energy rather than carbs.
How long does EPOC last after HIIT?
The EPOC effect for HIIT training lasts for 72 hours plus. In effect, what happens is that we “burn” a certain amount of calories during exercise, but depending on what type of exercise you do, you can extend the caloric burn for hours, on up to days after your exercise session.
Why do we need more oxygen after exercising?
Muscles performing work require increasing amounts of energy as the workload increases, which correspondingly requires more and more oxygen. We breathe more when we exercise to help remove the large amount of carbon dioxide (CO2) that is produced by the working muscles.
What happens to your breathing during EPOC?
Reynolds & Kravitz (2001) state that the following occurs during EPOC: replenishment of energy resources, re-oxygenation of blood and restoration of circulatory hormones, decrease in body temperature, and return to normal breathing rate and heart rate.
How many calories do you burn in EPOC?
Again, although every body is different and reacts differently to exercise, the EPOC effect burns roughly six to 15 percent of the total calories burned, Andrew said. So if you burned 200 calories during your workout, you will only burn an extra 12 to 30 calories after the fact.
Does HIIT have afterburn?
HIIT workouts typically utilize the latter more so than steady-state exercise, and will also require more oxygen post-sweat session-this is why these short bursts of intense, taxing exercise are associated with the afterburn effect.
Can you do HIIT every day?
HIIT is a great, safe, and effective workout, but there’s no need to do it every day. Keep it to three times per week. You’ll still reap the benefits and give your body time to recover properly.
Should you eat after a workout?
Eat after you exercise
To help your muscles recover and to replace their glycogen stores, eat a meal that contains both carbohydrates and protein within two hours of your exercise session if possible. Consider a snack if your meal is more than two hours away. Good post-workout food choices include: Yogurt and fruit.
Does your body keep burning fat after exercise?
You are always burning calories during your workout, but with the “afterburn effect,” your body continues to blast fat and calories long after you’ve left the gym.
Why is EPOC called afterburn?
Sometimes you might hear EPOC called “afterburn effect.” This references the calories that are burned after a workout when your body is repairing itself and getting back to its normal resting state.
What can cause oxygen debt in muscles?
Oxygen debt occurs when the body reaches a state of anaerobic respiration during intense exercise. When a person engages in high levels of physical activity, the body cannot distribute oxygen to the cells at a sufficiently rapid pace to keep up with the oxygen demand.
How long does EPOC last for?
Although some boutique fitness studios promise EPOC lasts 24 to 48 hours after an intense workout, Andrew said it’s much shorter than that: one to two hours, tops.
