30 minutes a day for exercise -probably not enough, study says

He tells KTRH that doubling up from a half-hour to a full hour of exercise per day can make a big difference.

This is one thing, research suggests, you should never be stingy about.

Heart failure occurs when the heart is not able to supply adequate amounts of blood to the rest of the body and is characterized by shortness of breath and a reduced ability to exercise. Berry said walking 30 minutes a day, for instance, may not be enough for a middle-aged person with hypertension, which presents an increased risk of developing heart failure.

The US recommended minimum levels of exercise were associated with only a slight decrease in heart failure risk, the researchers found.

And those who did four times as much – ten hours a week – had a 35 per cent lower chance of heart failure.

After going through the data of 370,000 people who were followed for more than 15 years, researchers from the University of Texas have come up with a new revelation that quite commonly said recommended dosage of 30 minutes of daily exercise may not be sufficient.

The research suggests that to improve prevention, higher levels of physical activity, up to twice the minimum recommended dose, are needed. This applies to all ages, genders, and races.

Lead study co-author, Dr. Ambarish Pandey-who is a cardiology fellow with the University of Texas, Southwestern Medical School-notes, “Future physical activity guidelines should take these findings into consideration, and potentially provide stronger recommendations regarding the value of higher amounts of physical activity for the prevention of heart failure”.

“Heart failure is a big public health concern and in contrast to the dramatic reduction in coronary disease that we’ve seen in the population, the incidence of heart failure remains relatively unchanged”, Berry said.

Heart failure affects more than 5.1 million adults in U.S.

Nutrition experts initially believed that any type of exercise is good exercise, but the most recent studies show that only certain physical activities can prevent heart failure.

Generalized least squares regression models were used to assess the quantitative relationship between physical activity (MET-min/week) and heart failure risk across studies reporting quantitative physical activity estimates.
