Mayo Clinic study finds high-intensity aerobic exercise may reverse aging (credit: Flickr user Global Panorama via Creative Commons license)<\/p><\/div>\n

A Mayo Clinic study says the best training for adults is high-intensity aerobic exercise, which they believe can reverse some cellular aspects of aging.<\/p>\n

Mayo researchers compared 12\u00a0weeks of high-intensity interval training (workouts in which you alternate periods of high-intensity exercise with low-intensity recovery periods), resistance training, and combined training. While all three enhanced insulin sensitivity and lean mass, only\u00a0high-intensity interval training and combined training improved aerobic capacity and skeletal muscle mitochondrial respiration. (Decline in mitochondrial content and function are common in older adults.)<\/p>\n

High-intensity intervals also improved muscle protein content, which enhanced energetic functions and also caused muscle enlargement, especially in older adults. The researchers said exercise training significantly enhanced the cellular machinery responsible for making new proteins. That contributes to protein synthesis, thus reversing a major adverse effect of aging.<\/p>\n

\u201cWe encourage everyone to exercise regularly, but the take-home message for aging adults is that supervised high-intensity training is probably best, because, both metabolically and at the molecular level, it confers the most benefits,\u201d says\u00a0K. Sreekumaran Nair, M.D., Ph.D.<\/a>, a Mayo Clinic endocrinologist and senior researcher on the study.<\/p>\n

He says the high-intensity training reversed some manifestations of aging in the body\u2019s protein function, but noted that increasing muscle strength requires resistance training a couple of days a week.<\/p>\n

In the study, researchers tracked metabolic and molecular changes in a group of young and older adults over 12 weeks, gathering data 72 hours after individuals in randomized groups completed each type of exercise. General findings showed:<\/p>\n
