Middle-age is not too late to start exercising. "Regular exercise training may provide protection against the future risk of heart failure with a preserved ejection fraction by preventing the increase in cardiac stiffness attributable to sedentary aging", they concluded.

"This study also demonstrated that exercise training can be adhered to by middle-aged adults over a prolonged period, suggesting that this may be an effective strategy to mitigate the deleterious effects of sedentary aging on the heart and forestall the development of heart failure with a preserved ejection fraction", Levine and colleagues said.

Researchers already knew that a lifetime of exercising 4 to 5 days per week helps keep your heart healthy.

Mr Lonergan - who previously struggled to climb a flight of stairs - now regularly exercises, and is a certified fitness instructor leading a high-intensity spin class at his local gym once a week.

To obtain the maximum benefit, the exercise s regimen must be begin at late middle age i.e. before the age of 65 years old, when heart seemingly maintains some ability and plasticity to remodel itself, say researchers from the Institute for Exercise and Environmental Medicine (IEEM), the collaboration between Texas Health Presbyterian Hospital Dallas and UT Southwestern Medical Center. Doctors actually look for a surge of troponins in people's blood when diagnosing a heart attack.

In an earlier study, researchers found that the exercise needs to be performed four-to-five times a week.

Individuals in good health despite a sedentary lifestyle still benefit from initiating an exercise routine in middle age, according to a randomized study.

After a while, all in the aerobics group transitioned to what Levine calls their weekly "maintenance dose" - one high-intensity interval session, one long session, a couple of regular base-training sessions and a recovery day, along with some strength training.

Study participants built up to those levels, beginning with three, 30-minute, moderate exercise sessions for the first 3 months and peaked at 10 months when two high-intensity aerobic intervals were added.

The committed exercise program also notably decreased cardiac stiffness.

Previous research suggests hearts become enlarged when the muscle is overworked due to an underlying condition, such as high blood pressure.

Since the study participants had gone decades without moving much, the coaches started them out slow. The group who was more involved in the physical activities have proper metabolism about the group which was involved in slow activities like yoga etc. In its most severe form, blood can back up into the lungs. People in this group worked up to doing exercises, such as four-by-fours defined as 4 sets of four minutes of exercise at 95 percent of their maximum heart rate - followed by three minutes of active recovery at 60 percent to 75 percent peak heart rate.

One was that volunteers were willing and able to participate in an intensive exercise regimen, which may not be the case for the general adult population.

After six months, most people in that group had ramped their efforts to between five and six hours of moderate-to-vigorous exercise per week.

Another session, lasting up to an hour, is a moderate-intensity activity that you'd barely think of as exercise - something like a brisk-paced walk, a game of tennis, a bike ride, or a similar activity you enjoy. The intense workout was also extremely important, Levine said, even if it was just once a week.

"It helps that we gave them a calendar, with every work out specified over the entire two years", he told Business Insider in an email.
