Walking with a pedometer as the intervention tool is becoming widely used in different health related domains to promote PA levels, and improve health status in a wide range of populations. Pedometers can supply valuable information on the number of steps and distance travelled, time spent in an activity, and also provide an estimate of energy expenditure [54]. The majority are a reliable and valid device for increasing and measuring physical activity, particularly as part of a walking programme [55]. In clinical studies pedometers have been widely used in the assessment and management of PA within a range of conditions including sedentary obese [56,57], diabetes [58], and knee osteoporosis [39,59], with an aim to encourage increased habitual physical activity, and improve health-related quality of life.
