Regular exercisers have the hearts and muscles of people decades younger than them – Brinkwire


Physically fit retirees have muscles almost identical to 25-year-olds, according to a study.

Experts at Ball State University in Muncie, Indiana, studied 28 people over 70 who have been practicing consistently since the 1970s to determine how active permanence can offset the physical decline associated with aging.

The results, published in the Journal of Applied Physiology, also found that those who work regularly scrape 30 years of the "biological" age of their bodies compared to their peers.

Interestingly, the subjects were not athletes, but people who adopted fitness in their lifestyle during the 1970s exercise boom.

"We were very interested in people who had started exercising during the race and exercise cycles of the 1970s," said Scott Trappe, professor of exercise science and senior author of the study.

"They exercised as a hobby."

Using social media, the researchers found that 28 people have maintained this level of activity for five decades.

They also recruited two other groups: inactive 70 years and fit 20 years.

The scientists tested the participants' aerobic capacities and measured the number of capillaries and enzymes in their muscles – high levels of which demonstrate muscle health.

Curiously, the muscles of the older exercises matched those of the 20-year-old.

Likewise, they had far more capillaries and enzymes in their muscles than inactive retirees – which meant that they effectively avoided the physical impact of old age.

In fact, the only difference between the two active groups – young and old – was a slightly diminished aerobic potential.

But for fit pensioners, this was still 40% higher than their sedentary peers.

In addition, when data were compared to national averages at different ages, active retirees had the cardiovascular health of people 30 years younger.

The results suggest that an aging population could "build a reserve" for good health, the researchers said.

"These people were so strong," Trappe said.

"I'm in my 50s and they certainly inspire me to stay active."
