Health Desk: 13 January 2018:  Exercising four to five times a week can reverse damage to sedentary, aging hearts and help prevent the risk of future heart failure, a study has found.

To reap the most benefit, the exercise regimen should begin by late middle age (before 65) when the heart apparently retains some plasticity and ability to remodel itself, researchers said.

Exercise needs to be performed four to five times a week. Two to three times a week is not enough, researchers said. “Based on a series of studies performed by our team over the past five years, this ‘dose’ of exercise has become my prescription for life,” said Benjamin Levine, from the University of Texas in the US.

The regimen included exercising four to five times a week, generally in 30-minute sessions, plus warmup and cool-down. The more than 50 participants in the study were divided into two groups, one of which received two years of supervised exercise training and the other group, a control group, which participated in yoga and balance training.

At the end of the two-year study, those who had exercised showed an 18 percent improvement in their maximum oxygen intake during exercise and a more than 25 percent improvement in compliance, or elasticity, of the left ventricular muscle of the heart, Levine said.

However, the researchers also found that the heart chamber in competitive masters-level athletes remains large and elastic and that even four to five days of committed exercise over decades is enough for non-competitive athletes to reap most of this benefit.
