EPOC...Oh Snap.

[Joe Birch]

If there's no difference in fat loss then all the more reason to advocate high intensity exercise > LSD since there are countless peer reviewed examples (as well of plenty of opinions from those who've tried both) of the potential aerobic, anaerobic and strength benefits you can gain from short bouts of intense exercise compared to longer bouts of steady state exercise.

(P.S. not trying to imply that LSD has no role in some peoples training).

Derek,
There's no missing second E, it goes like this: "Excess Postexercise Oxygen Consumption".

I love my "LSD" hill walks on the weekends, great for stress relief and getting outdoors. Movement without much "effort" required, physical or mental. However, if I relied on those for my fitness, well, my fitness wouldn't be much at all.

When exercise is hard, make it hard, when it is easy, make it easy. Hanging around too long in that middle area is what I don't think people should do too much of.

There is a difference in FAT loss. For example:

http://www.exrx.net/FatLoss/HIITvsET.html

There is no difference in EPOC as EPOC calories burned are insignificant. That does not mean isn't a difference in body composition changes.... because of *nutrient partitioning.*

[Emily Mattes]

If there is still an ultimate difference in body composition changes, then why not advocate that as a reason to do interval-type training, and why worry about advocating EPOC at all? Seems silly to focus your advocacy on an effect that apparently doesn't exist when there are so many good effects that do exist.

[Derek Weaver]

Garrett,
Thanks. I need to brush up on my fancy fitness acronyms.

Emily,
Any hard training should improve p-ratio, through insulin sensitivity and other mechanisms. Interval training is simply the most fun way to achieve the desired effect.

[Mike ODonnell]

Most people who enjoy the benefits of interval training also usually have a high lifestyle activity factor (plenty of other activity to oxidize "burn" fat). Anyone selling intervals ONLY usually neglects to mention that whole part.....or just wants your money.

Someone else posted an article on here about how growth hormone is the main contributor to fat loss. Now, dont we all know that GH is released when you do short intense bursts of movements, aka, intervals?

On the flip side though, LSD training does train your body to burn fat instead of carbs for energy because there is no way to ingest enough carbs to cover a 3 hour race, let alone 24hr + races. But, it does inhibit GH as well as burn muscles.

For these reasons, id always push it up to 90%+ of max for the last few miles of my LSD runs to try and promote GH.

They both work, just differently, and for different reasons. We're trying to compare apples to oranges.

[Dave Van Skike]

eating less than is required for activity is the main contributor to fat loss.

see the faces of sly stallone, and mickey rourke for a clue on the amounts of GH required to make a Significant Difference in fat loss when compared to the whole eating thing....

one could devote a lot of time to navel gazing and pondering the exercise science in the hopes of beating researchers to the punch vis a vis manipulating one's hormonal profile...or, one could forget the whole line of BS and just.......you know,..... try it and see what works in the only experiment that matters.

Hence why you do some sort of short/explosive training for GH release and THEN go for some slower movements.....the combination works, not just doing 4 min of burpees and then going to sit and watch TV. GH releases the fat....then you still have to burn it in the muscle in an oxygen environment....aka aerobic state.

Allen, i believe he did say that but although he may have had the detail wrong he was still doing the right thing. He compared it to electricity saying that if we suddenly discovered that electricity worked completely differently to how we currently believed we would still flick the switch on the wall to light our homes.
