Hurry up for your health: according to a new study, walking faster may lower the risk of heart failure.
Published Thursday in the Journal of the American Geriatrics Society, showed that less than one hour of fast weekly walking led to the same heart-health benefits as casually walking for more than two hours a week.
Dr. Charles B. Eaton, the study鈥檚 senior author, is a physician, clinical epidemiologist and medical professor at Brown University in Rhode Island.
鈥淭his study confirms other studies demonstrating the importance of walking speed on mortality and other cardiovascular outcomes,鈥� he said in a .
The study looked at the walking habits and heart health of 25,183 mobile and postmenopausal women, aged 50 to 79. When the researchers followed up with them after approximately 17 years, 1,455 women said they had been hospitalized for heart failure.
The researchers found that compared with those who reported walking at a casual pace of less than 2 mph (3.2 km/h), the women who walked at an average speed of 2 to 3 mph (4.8 km/h) had a 27-per-cent lower risk of heart failure, while the faster walkers had a 34-per-cent lower risk.
鈥淭he risk of heart failure associated with fast walking with less than 1 h/week walking duration was comparable with the risk of heart failure鈥� among casual and average walkers with more than 2 h/week walking duration,鈥� the study also reported.
Adult humans generally walk at about 5 km/h, around the same rate as the study鈥檚 speedy seniors.
In a busy world, Dr. Eaton says picking up the pace may be key to healthier hearts.
鈥淕iven that limited time for exercise is frequently given as a barrier to regular physical activity,鈥� he explained, 鈥渨alking faster but for less time might provide similar health benefits as the recommended 150 minutes per week of moderate physical activity.鈥�
