Ex­er­cise stim­u­lates help­ful hor­mone

Runner's World (UK) - - Warm Ups -

If you’re strug­gling for mo­ti­va­tion to get out for your next run, re­mind your­self of a re­cent find­ing from the Univer­sity of Florida, US. Re­searchers there have found that ex­er­cise trig­gers a surge of a hor­mone called irisin, which then launches a three-pronged at­tack on fat: it helps to turn your body’s calo­rie-stor­ing white-fat cells into en­ergy-hun­gry brown-fat cells; it in­creases the amount of en­ergy used by those cells; and it sup­presses the for­ma­tion of fatty tis­sue. Ear­lier stud­ies by the same sci­en­tists found that irisin also played a role in im­prov­ing car­dio­vas­cu­lar and bone health.
