HIIT cardio and the calories burned.
I do hiit cardio every other day. I have seen good results with it but I don't really know the science behind it.
I know that it makes ur body burn calories the whole day.
But by how much.
How many calories would I be burning at rest on cardio days compared to non cardio day?
2x mor 3x more?
And how much fat would someone lose when doing hiit compared to jst jogging?
I don't know this because my diet and routine are on point and even if I didn't do the hiit I would still be losing the fat
Some one shed some light on this please

your metabolism definitely stays more elevated for longer after hiit, but i don't know the exacts.
i would guess it varies person to person

How many calories your body burns are rest on cardio as opposed to cardio days will depend on far more than the cardio done, like whether or not you do resistance training on those days, eating habits, age, sex, muscle mass, etc.
It's also proven that high intensity cardio burns more fat than low-intensity, steady-state cardio. I actually have just written a brief article on high-intensity versus low-intensity cardio for fat loss for LG - it will be up on their new website (when the website is complete).

There's a more complex explanation involving Heart Rate, Heart Rhythm, Respiration Rhythm, Muscle Rhythm, Blood/Oxygen Demand & Circulation, Oxygen Debt and Muscle Adaptation that all equates to over-all increased metabolism. Not to mention some endocrinological effects that HIIT elicits that static cardio does not. However, without the need to understand all the mumbo jumbo, my first paragraph should paint some general clarity.

I use anywhere from 10.5-21g, but 10g per dose is sufficient.

Minus the micro technical aspect of distance traveled in my analogy, the macro comparison of HIIT vs static cardio using steady freeway drive vs light signal to light signal sprints still stands. I'm fine with giving college grade lectures if asked, but when someone doesn't comprehend with much depth the difference between HIIT and static cardio, the priority is to provide general clarity, not confusing technicalities, which I understand, you were not wrong factually, in pointing out.

If you consume any thing during or intra workout your body will use that for fuel. I take pre workoutbcaa &creatine but I take them one hr pre wo

I hate to be overly critical (I find your posts generally well informed and helpful), but when I was getting my graduate degree, it was always imparted on me that the mark of truly grasping a concept is possessing the ability to explain it so simply that "your grandmother could understand it".
I hate it when academics use high brow language to obscure their arguments--it smacks to me of a defense mechanism.

High Intensity Cardio for More Effective Fat Loss
THE CARDIO DEBATE FOR FAT LOSS:
HIGH INTENSITY VERSUS LOW INTENSITY
Written for LG Sciences by Rosie Chee Scott, BExSpSc
18 August 2010
It is a mistaken belief that long and slow, low intensity cardio is best for fat loss because it utilizes the aerobic system and burns fat during exercise. High intensity cardio is actually far superior and more effective for fat loss than low intensity cardio for several reasons. This article will briefly discuss the differences in high intensity and low intensity cardio, outlining the reasons why high intensity cardio is more efficient and effective for fat loss.
High intensity cardio requires less time to perform an effective session than low intensity cardio, which makes it a much more convenient mode of cardio for those with limited time in which to train.
Although high intensity cardio primarily uses carbohydrates for fuel, the higher oxygen deficit post-training causes the body to use fat for energy. High intensity cardio elicits a higher work response from the body than low intensity cardio, thus burning more overall calories throughout the day, even if not during the training session. Training the body to perform at a high intensity will also increase your body’s tolerance for work, and therefore the body will burn fat at a higher level, sparing muscle glycogen.
Because of the higher force of muscle contraction during high intensity cardio, there is a greater rate of GLUT-4 translocation within the muscles, creating a stronger nutrient repartitioning effect, which in turn enables the body more efficient and effective used of substrates.
High intensity cardio has a higher oxygen deficit than low intensity cardio. Training with a higher oxygen deficit actually increases the body’s maximum oxygen capacity more than low intensity cardio. The higher the body’s maximum oxygen capacity, the more efficient the body is at oxygen transportation, and thus more efficient the body is at burning fat, since fat requires oxygen to be oxidized.
High intensity cardio elicits a similar hormonal response from the body as resistance training does, but without the stress and strain on the body and the nervous system that resistance training has. Higher insulin sensitivity, more Growth Hormone and IGF-1 release makes the body more effective at burning fat.
Burning fewer calories during the training session makes high intensity cardio more muscle sparing and less catabolic than low intensity cardio.
High intensity cardio uses fast oxidative (i.e. Type IIa) and fast glycolytic (i.e. Type IIb) muscle fibres. Muscle hypertrophy occurs primarily through chronic anaerobic, high-intensity exercise. The more muscle mass an individual has, the greater the ability of their body to burn fat.
If you want to lose fat quickly and efficiently, high intensity cardio is the best mode of cardio to incorporate into your training programme. Not only does it require less time to complete, but it burns more overall calories throughout the day. High intensity cardio makes the body more efficient at using oxygen and elicits the same hormonal response as resistance training - without the stress on the body - allowing for the same fat burning ability. High intensity exercise is also muscle sparing, due to the shorter exercise period performed and less calories burned during the session, allowing the body to be a more effective fat burning machine, since more muscle mass means a greater ability for the body to lose fat.

Please note that this article provides a very brief overview on why high intensity cardio is more effective than low intensity cardio for fat loss. If a more in-depth explanation is required, I recommend doing some personal research on the topic.

I'm pretty sure I know how to learn and understand material if I've made it this far in academics. I could simplify like I said in my previous post, but not unless asked. I also keep information at a basic and superficial level as previously mentioned for the majority. If anyone feels like they need a further explanation feel free to seed me a PM.
