Is strolling sufficient? Science finds the right way to undo well being dangers of sitting all day

A brief stroll each half hour can assist reverse the well being harm related to lengthy durations of sitting, in response to a brand new examine.

Mounting proof means that sitting for lengthy durations – an inescapable actuality for a lot of staff – is hazardous to well being, even for individuals who train often.

Within the new examine, volunteers who bought up and walked for 5 minutes each half hour had decrease blood sugar and blood stress than those that sat on a regular basis.

To search out one of the simplest ways to fight the deleterious results of sitting, Diaz and his workforce examined 4 completely different “exercise snacks” on 11 volunteers: one minute of strolling each half-hour whereas seated, one minute after 60 minutes in a seated place, 5 minutes after half-hour in a seated place and 5 minutes after 60 minutes in a seated place. The consequences of every of those methods had been in comparison with these of sitting with out a break.

Every of the 11 grownup volunteers got here to the researchers’ lab the place they sat in an ergonomic chair for eight hours, getting up just for a restroom break and any exercise snacks they had been instructed to carry out. All 11 adopted every of the methods, one by one, together with an eight-hour interval throughout which they solely bought up for lavatory breaks.

Blood stress and blood sugar had been measured throughout every section of the examine. The technique that labored greatest was to stroll 5 minutes for half-hour in a seated place. This technique additionally had a dramatic impact on how the volunteers’ our bodies responded to massive meals, producing a 58% discount in blood stress spikes in comparison with sitting all day.

All strolling methods resulted in a big 4-5 level discount in blood stress, in comparison with sitting nonetheless each eight hours. Every kind of exercise snack, apart from a one-minute stroll each hour, additionally resulted in a big lower in fatigue and an enchancment in temper.
