Effect of treadmill and overground walking on function and attitudes in older adults.

Purpose: The purpose of this study was to determine whether treadmill walking, as a mode of physical activity for older adults, was comparable with overground walking when considering 1) spatiotemporal gait characteristics (walking velocity, stride length, and stride rate) at a preferred velocity and a prescribed intensity typical of many exercise prescriptions (i.e., RPE of 13); and 2) the effects on physical function (short physical performance battery (SPPB), lateral mobility, 400-m walk) and participants' attitude towards training and level of enjoyment.
