Another study published this November by the American Heart Association in their Circulation Journal looks at the impact of walking on heart health. For 10 years they studied over 4,000 elderly patients, looking at their walking habits. They found that those who walked more frequently did slightly reduce their risk of heart problems, however, there was a clear distinction between slow and fast walkers. They found that individuals who walked faster than 3mph (4.8kmph) had a significantly reduced risk of all types of heart and circulatory problems (heart disease, heart attack and stroke) than those who routinely walked slower than 2mph (3.2kmph). So, if you want to protect your heart into your old age, go for regular short and brisk walks to get your heart pumping and increase your respiration rate.
