A team of researchers at Tufts University, in the US have found that walking longer or faster can have cardiovascular health benefits for older adults, even for those over the age of 75.
The team, led by senior author Dariush Mozaffarian, looked at a large group of 3,941 men and women over a 10-year period, noting participants' exercise habits including walking distance and walking pace, as well as other leisure activities such as mowing the lawn, gardening, swimming, biking, and hiking. The mean age of the group was 73 at the start.
