"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.

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