Mayo Clinic Study on HIIT Exercise

Post by jocko6889 » Wed Jul 24, 2019 12:49 am

It's becoming more and more clear that the effects of NMN are greatly amplified by exercise. According to a new study by the Mayo Clinic, it looks like HIIT training (high intensity interval training) is the best way kick mitochondria into high gear.

"Mayo Clinic study: HIIT has 'anti-ageing benefits'

A study by Mayo Clinic has suggested that high-intensity interval training (HIIT) can reverse signs of ageing at the cellular level.

The research, published in the Cell Metabolism journal, studied 72 sedentary adults divided into two age groups of "young" (18 to 30 years old) and "older" (65 to 80 years old).
Each individual was then assigned one of three 12-week workout routines – HIIT cycling, strength training or a regime combining the two.

All training types improved lean body mass and insulin sensitivity, but only HIIT and combined training improved aerobic capacity and mitochondrial function for skeletal muscle. A decline in mitochondrial content and function are common in older adults.

HIIT also improved muscle protein content that not only enhanced energetic functions but also caused muscle enlargement, especially in older adults.

The researchers concluded that HIIT significantly enhances the cellular machinery responsible for making new proteins. That, in turn, contributes to protein synthesis which can reverse the adverse effects of ageing. Adding resistance training, however, is important to achieve significant muscle strength.

“We encourage everyone to exercise regularly, but the take-home message for ageing adults that supervised HIIT is probably best, because, both metabolically and at the molecular level, it confers the most benefits,” said K. Sreekumaran Nair, a Mayo Clinic endocrinologist and senior researcher on the study.

HIIT is great! I don't take any formal HIIT exercise classes but I try to incorporate some into my general exercise, like through running and swimming - for example, if I'm doing a short jog, I will do a couple of sprints in between; if I'm swimming, I will do some sprints in the pool to break up the monotony. Some sport are also great for HIIT, like hockey and basketball.

I agree - and generally any exercise that gets you into the aerobic phase, where you have an elevated heart rate for at least 15 minutes, is going to release or stimulate hormones, like endorphins as well as neurotransmitters like dopamine, nor-epinephrine, and serotonin.

They bathe your blood of bad hormones, like cortisol, and the stress related catecholamines, and thus act as a system wide anti-inflammatory.

A huge conflict with bodybuilding is gaining size while still trying to lose fat. HIIT is the key to get around this. To gain muscle you lift weight. To lose fat you do cardio. With tradition methods of cardio (such as 60 mins of running) we actually counteract the muscle gains attained by weight lifting and lose muscle mass.

With HIIT cardio you can deplete your energy stores by 15% with as little as 10 seconds of HIIT (something that could take up to 60 minutes with traditional cardio)
another added bonus to HIIT cardio is instead of burning fat for the duration of your workout, you actually burn fat ALL DAY LONG! and yet you maintain your muscle mass and can actually gain muscle from this practice.
