Is High Intensity Interval Training the fountain of youth?

It could be, says recent research into HIIT. A UK study showed that higher levels of exercise than the minimum requirement (150 minutes a week of moderate exercise or 75 minutes of brisk) improves your sex life, your sleep, your mood, energy, and helps battle diseases such as diabetes two, cardiovascular problems, and certain cancers. 

Most of us don't get the 150 minutes of brisk walking, classed as a moderate exercise, that doctors recommend. Only one in five take the time to do this, and this inaction, apparently, is a leading cause of premature death.

Research also shows that while moderate is good—extreme exercise, even in short bursts, is better. Experts recommend not only keeping active—but say that HIIT as the way to go. Even if you only take the stairs instead of waiting for the elevator, you'll be doing yourself a favor, as this gives you a burst of activity. Read the CBC Report for more.

HIIT can stop cellular aging and rejuvenate the cells that create 'old' age and cause damage in the body, they say. Mayo Clinic research examined whether strength training or HIIT (high-intensity cycling, for example) had better results. The outcome for HIIT was astonishing at the 'cellular level.'

Strength training versus high intensity

Strength training helped with muscle mass, as expected. For the HIIT group, the mitochondrial functioning, which is needed to sustain life, improved by 69 percent among older study participants.  It improved insulin levels, heart and lung health, and other age-related declines. The conclusion was that there is no substitute for exercise to delay your body's aging process. And your best choice to keep on rejuvenating? The recommendation is to switch every few days between strength and HIIT—and that even choosing to take the stairs as a form of HIIT can be of huge benefit. From the Sydney Morning Herald.
