Lift your way to men­tal sharp­ness

Hindustan Times (Patna) - Live - - Lifestyle -

You may be sur­prised by what a quick work­out ses­sion can do to your brain. A new study in­di­cates that lift­ing weights twice a week helps to com­bat a de­cline in brain health, par­tic­u­larly in women. Past stud­ies have ex­plored the ben­e­fi­cial im­pact of phys­i­cal ac­tiv­ity such as run­ning, walk­ing, and aer­o­bics on the body, but few have looked at lift­ing weights. This was no­ticed by re­searcher Teresa Liu-Am­brose of the Univer­sity of Bri­tish Columbia in Van­cou­ver, Canada. Her team sought to find out how en­gag­ing in sport would be ben­e­fi­cial for brain. They stud­ied the im­pact of lift­ing weights, which strength­ens and builds mus­cles. As in the brain, mus­cles tend to weaken and shrink with age, af­fect­ing move­ment, par­tic­u­larly walk­ing. The re­searchers sought to ver­ify if lift­ing weights could change this process and play a pos­i­tive role in the de­cline of the brain’s ca­pa­bil­i­ties. The find­ings in­di­cate that the women in the con­trol group showed a sig­nif­i­cant in­crease in the num­ber of white mat­ter le­sions. Also, the scans of the par­tic­i­pants who lifted weights twice a week showed less shrink­age of their white mat­ter. For this, how­ever, Liu-Am­brose says that “a min­i­mum thresh­old of ex­er­cise needs to be achieved,” noted the NY­Times.
