Exercise can help decrease the risk of hypertension in people with a family history of high blood pressure, according to a study published in the journal Hypertension.
The publication of the American Heart Association reports a study of more than 6 thousand people shows that participants who had a relative with high blood pressure, but were in a good shape had a risk a 34% lower themselves to develop high blood pressure.
“It’s important to understand the role of family history and physical condition,” said Robin P. Shook, Arnold School of Public Health at the University of Southern
The study received funding from the National Institutes of Health and a grant, without limitation, the Coca-Cola.
“The results of this research show a practical message: even a very realistic and moderate exercise? For example, 150 minutes of brisk walking a week, provides enormous health benefits, particularly for people predisposed to hypertension due to family history, “said Shook.
Previous studies have shown that family history is responsible for 35 to 65% of the variability in blood pressure between children with varying levels of risk depending on which parent has developed and age of onset of the problem.
The researchers followed a group of 6 000 278 people, predominantly white, aged between 20 and 80, over an average of 4.7 years.
Thirty-three participants indicated that their father or mother had hypertension.
When he began the study all participants were healthy, had no medical diagnosis of hypertension, and marked by at least 85% of predicted maximum heart rate for their age.
The researchers determined the cardiorespiratory fitness of the participants using an exercise test on the treadmill that reached the maximum for each participant.
During the 1545 survey participants indicated they had developed hypertension.
The researchers found that, taken together people with and without family history of high blood pressure, high fitness levels appeared related to a 42% lower risk of developing hypertension.
Moderate levels of physical fitness lowered the risk by 26%.
People who had a low level of physical fitness and a relative with hypertension showed a 70% greater risk of developing hypertension, compared with people with good fitness and no family history of hypertension.
