Fitness may be a strong predictor of high blood pressure, according to a study linking increased fitness levels to reduced risk of hypertension.
Hypertension, often referred to as high blood pressure, is a potentially life-threatening condition that affects one in three U.S. adults. Not only does high blood pressure often cause no symptoms, it drastically increases risk of heart disease, heart attack and stroke. The good news is that regular physical activity helps promote a healthy blood pressure and according to research, the more fit you are, the lower your blood pressure may be.
Published in the Journal of the American Heart Association, this study tested the fitness levels of more than 57,200 individuals participating in The Henry Ford Exercise Testing Project, which studied the relationship between fitness and heart health. Using treadmill stress tests, researchers tested the fitness level of participants between 1991 and 2009, and then collected key health information, including blood pressure, for roughly four-and-a-half years.
At the beginning of the study, researchers found that individuals with the lowest level of fitness were 70% more likely to already have high blood pressure compared to those with the highest fitness level. And after follow-up, researchers found that individuals with the highest fitness level were 20% less likely to develop high blood pressure compared to those with the lowest fitness level. Perhaps most importantly, these associations remained true regardless of age, sex, race, and weight.
