Lose Weight Quickly by Exercising the Right Way

gezondensnelafvallen

I heard from some body builders, that it is good to do a really hard work out for 10 minutes 4 times a day and rest every second day. That way you build up your metabolism and burn more calories.

Walking doesn’t have much of an after-burn effect but some exercises do.

6 second bursts of cycling for 10 reps… That’s the type of exercise that burns fat and your body needs to recover from.

Afterburn Effect: Burn 500+ Calories from 10 Minutes of Exercise?

Lose Weight - Dr Christopher Scott afterburn Afterburn Effect: Burn 500+ Calories from 10 Minutes of Exercise?

I have an interview below with Dr. Christopher Scott, PHD, who is an exercise physiology professor at the University of Southern Maine and one of the world’s foremost experts on the Afterburn Effect, which is calorie burn AFTER exercise.

As you’ll learn in a moment, you can harness the power of the afterburn effect to burn more fat in MUCH less time working out.

Surprisingly, very few people in the exercise physiology community and more generally in the fitness industry have acknowledged his pivotal research and its potential to change public health policy and your ability to burn more fat in less time.

I was able to get Chris on the phone and record a 40 minute conversation with him. You can play the audio of our conversation below, download the 20-Page transcript, or view the summary and highlights I put together below.

Summary & Highlights: Afterburn Interview

 

What is Energy Expenditure?

Energy expenditure refers to the amount of energy a person uses during all bodily activities from movement, to blood circulation, to breathing, to digestion. Energy Expenditure is measured in calories, a unit of heat, and is represented by the symbol kcal.

What is Aerobic vs. Anaerobic Exercise?

Aerobic exercise is a type of activity marked by long distances and slow paces like running, or cycling. Anaerobic exercise is marked by activities that require strength, speed, and power like weight lifting, or sprinting.

Understanding Energy Expenditure: 3 Components

afterburn effect of exercise 1 Afterburn Effect: Burn 500+ Calories from 10 Minutes of Exercise?

1) Calories Burned During Exercise (O2) – Oxygen uptake is proportional to heat expenditure during normal aerobic exercise. For this reason, calorie burn during aerobic exercise is easy to estimate using a metabolic cart.

2) Calories Burned From Exercise (EPOC) – At higher exercise intensities, oxygen uptake is NOT proportional to heat expenditure. An oxygen debt is created, where EPOC (excess post-exercise oxygen consumption) is used to help restore the body to a resting state and adapt it to the exercise just performed, which requires energy.

3) Lactic Acid Contribution of Exercise – EPOC is NOT enough to fully account for anaerobic contribution of exercise to total energy expenditure. This is a VERY important point and what differentiates Chris’ research. Chris has proposed that by measuring blood lactate reasonable estimates of rapid glycolitic ATP turnover are available and should not be omitted from the estimation of energy expenditure from anaerobic exercise, especially when anaerobic contributions are large.

The Afterburn Effect Can Be BIG

Energy Expenditure component #2 is typically referred to as the “Afterburn Effect”, when it should really be #2 and #3. The afterburn effect is minimal for traditional cardio, but can be significant for strength and power related activities.

In his first major study, Chris proposed that as much as 95% of the calorie cost of intense anaerobic exercise can come AFTER exercise! While Chris says the numbers are not perfect estimates and were used to help highlight the importance of anaerobic contribution to exercise, they are still revealing.

Why Most Exercise Physiologists Estimate Anaerboic Exercise Incorrectly

One reason may be that the exercise industry is dominated by aerobic exercisers like runners, cyclists, and triathletes:

“I think that the way scientists have started the origins of exercise physiology are pretty much all aerobic exercise. That’s what it is. Now many people are applying aerobic exercise concepts like long-distance running and cycling, and they’re using what they found there and applying it to resistance training and weight lifting. That’s where I pretty much have drawn the line. I’m not going to do that.”

A Possible 4th Component of Energy Expenditure – Hypertrophy

While Chris did not separate out the effects of Hypertrophy as a possible 4th component, he did note that it does require energy and that it’s not being estimated/measured.

“If you’re working your muscle to the point where you’re causing damage at the microscopic level, it’s going to take energy to repair that… breaking proteins and laying down new proteins, that is most certainly going to be raising your energy expenditure…There’s also medical issues, if you will, that increase energy expenditure, and the largest one is burns. If you’re a burn victim, you can literally double your resting metabolic rate with severe burns. The reason why is you look at your skin, which is mostly protein, you’re laying down new protein. Your nutritional demands are literally off the chart.”

High Intensity Anaerobic Exercise Burns More Fat Than Cardio

“There was a study I saw years ago, and I still quote it, and they were doing these six-second bursts of all-out cycling. It was 10, 15 sets of this, and they found this unheard of amount of free fatty acids that were broken down from fat stores within the muscle. It begs the question why, during an anaerobic activity that clearly utilizes glucose as a fuel, why is so much fat being broken down?

The answer appears to be, well, the exercise component is six seconds long, and that’s using glucose, but however long the recovery component is, that’s when you’re burning fat. If you add all these intermittent periods together…you’re primarily burning lactate and fatty acids, and that’s where the body composition stuff comes in.

If you want to lose weight, lose body fat, get ripped, I’m under that impression that intermittent bursts of high-intensity activity followed by rest periods, that’s the way to do it.”

And one more add on:

“A similar thinking [by many health organizations] was that if you wanted to burn fat, you would have to do long, slow, distance activity because that’s going to burn the most fat. We’re starting to realize now that in fact it’s the other way around that during really brief, intense intermittent bouts of strength, speed and power-related stuff, I’m under the impression you can burn even more fat.”

Nutrition Is Still King For Losing Fat

“Then another thing I always tell people – I’m not a nutritionist, obviously, but I know a little bit about it – if you really were to come to me and wanted to lose weight, and we made a list of ten things, one through seven of them would be dietary, watching what you eat. Then eight, nine and ten would be exercise.”

The Afterburn Effect: Research Still Has a LONG Way to Go

“We have a long way to go before we understand this, and that there are times when it’s almost – for me, from a scientific standpoint – it’s almost overwhelming because we’re finding out that isotonic contractions are different than isometric, that are different from isokinetic. Then you add different one repetition maximums or ten repetition maximum, how much exercise time’s involved, number of reps, the number of sets, the number of rest periods in between sets.

We have a long way to go before we find the perfect exercise program, if you will. The truth of the matter is there’s probably not one perfect program. There’s probably dozens of perfect programs. Again, it all goes down to the independence of the person that’s involved. What’s actually best for them?

The bottom line, though, I think, though, Marc, and again, from anecdotal evidence that I’ve heard from you and others, is that when you really start doing the intermittent large muscle group, high-intensity-type exercise, that’s when people start getting into these ripped, cut, nice body composition adjustments.”
