At 75, you can feel at 40, but you need to sweat

By studying consistently exercising seventy-year-olds, the researchers found that their heart and lung capacity, as well as muscle form, were similar to those of healthy forty-year-olds.

Regular exercise throughout life rejuvenates the body for decades, says a new study from Ball State University published in the Journal of Applied Physiology.

The researchers recruited people who had been regularly involved in running, cycling, swimming, or any other type of physical activity for several decades. The average study participant is a lifelong physical educator who exercises as a hobby and devotes about five days a week to exercise for a total of about seven hours.

By studying consistently exercising seventy-year-olds, the researchers found that their heart and lung capacity, as well as muscle form, were similar to those of healthy forty-year-olds.

“Exercise wins” is key. We have seen that people who exercise regularly year after year have better overall health. These 75-year-olds - men and women - have the same cardiovascular health as those in their 40s and 45s,”said research team leader Scott Trappe.

The participants' cardiovascular health was assessed as follows - using a stationary bike, VO2max (the maximum amount of oxygen that a person can use during intense exercise and aerobic endurance) was determined. Each participant also underwent a muscle biopsy to determine capillarization and aerobic enzyme activity.

Typically, after 30 years, VO2max decreases by about 10% every 10 years. An increasing decrease in VO2max is directly related to an increased risk of multiple chronic diseases, mortality and loss of independence.

The researchers also divided the male subjects into two groups:

productive (intensive life-long training of a competitive nature),

  • just fitness.

“For some of the variables, the productive group had some indicators that outperformed the fitness people, and cardiovascular capacity was one of them,” Trappé said. “But things like muscle and capillary health to maintain blood flow were equivalent between the two groups. Higher intensities did not necessarily rank them higher."

The study provided a unique opportunity to assess the physiological benefits of lifelong aerobic exercise by comparing 70-year-old athletes to their younger counterparts and sedentary peers.

“The really interesting thing about this study was that these people came from a generation of training boom that really started in the 1970s, when running and tennis became massively popular,” Trappé said.

While younger people can handle more intense workouts, many 70-year-olds have found new ways to maintain their health at a fairly high level, the researchers concluded. Thus, for anyone, 30-60 minutes of exercise a day is the key to a healthy life.
