New study links bet­ter car­diores­pi­ra­tory fit­ness with a longer life

Aer­o­bic fit­ness is some­thing that most pa­tients can con­trol. And we found in our study there is no limit to how much ex­er­cise is too much.

New large-scale re­search pub­lished in the Jour­nal of the Amer­i­can Med­i­cal As­so­ci­a­tion has found that a higher level of car­dio­vas­cu­lar fit­ness is linked to a lower risk of death, es­pe­cially in those with an ex­tremely high level of fit­ness. Car­ried out by re­searchers at Cleve­land Clinic in the US, the new study looked at 122,007 par­tic­i­pants who un­der­went ex­er­cise tread­mill test­ing to as­sess the as­so­ci­a­tion be­tween car­diores­pi­ra­tory fit­ness and all-cause mor­tal­ity.

Par­tic­i­pants were di­vided into five fit­ness per­for­mance groups – elite, high, above aver­age, be­low aver­age and low – with elite per­form­ers de­fined as hav­ing aer­o­bic fit­ness in the top two and half per­cent by age and gen­der, and demon­strat­ing fit­ness lev­els com­pa­ra­ble to those of en­durance ath­letes. The re­searchers also gath­ered data on age and sex of par­tic­i­pants, height, weight, and body mass in­dex, smok­ing sta­tus, and any med­i­ca­tions or ex­ist­ing dis­eases such as a his­tory of car­dio­vas­cu­lar dis­ease, di­a­betes, or hy­per­ten­sion.

Af­ter tak­ing into ac­count these fac­tors, the find­ings showed that in­creased car­diores­pi­ra­tory fit­ness was di­rectly as­so­ci­ated with re­duced long-term mor­tal­ity. In ad­di­tion, the re­searchers also found that there with no limit to the pos­i­tive ef­fects of aer­o­bic fit­ness, with ex­treme aer­o­bic fit­ness as­so­ci­ated with the great­est ben­e­fit.

This find­ing was es­pe­cially notable in older pa­tients and those with hy­per­ten­sion. In those over the age of 70, elite per­form­ers ben­e­fited from a nearly 30 per cent re­duced risk of mor­tal­ity com­pared to high per­form­ers, and for pa­tients with hy­per­ten­sion, the elite per­form­ers again showed a nearly 30 per­cent re­duc­tion in all-cause mor- tal­ity com­pared to high per­form­ers.

“We were par­tic­u­larly in­ter­ested in the re­la­tion­ship be­tween ex­tremely high fit­ness and mor­tal­ity,” com­mented lead au­thor Dr Kyle Mand­sager, “This re­la­tion­ship has never been looked at us­ing ob­jec­tively mea­sured fit­ness, and on such a large scale.” The study’s find­ings high­light the long-term ben­e­fits of ex­er­cise and fit­ness, even to ex­treme lev­els and re­gard­less of age or ex­ist­ing dis­ease.

The au­thors added that health­care pro­fes­sion­als should be en­cour­ag­ing pa­tients to achieve and main­tain high lev­els of fit­ness, al­though they also noted that pa­tients should al­ways check with their health­care provider be­fore start­ing an ex­er­cise pro­gramme. “Aer­o­bic fit­ness is some­thing that most pa­tients can con­trol. And we found in our study there is no limit to how much ex­er­cise is too much,” said se­nior au­thor of the study Dr Wael Jaber. “Ev­ery­one should be en­cour­aged to achieve and main­tain high fit­ness lev­els.” – Re­laxnews
