“…Many long-term interventions (not less than 10 weeks) have been administered to patients with obesity (e.g., Schneider, Bassett, Thompson, Pronk, &Bielak, 2006), diabetes (e.g., Swartz, Strath, Bassett, Moore, Redwine, Groër, et al, 2003), and hypertension (e.g., Moreau, Degarmo, Langley, McMahon, Howley, Bassett, et al, 2001). On the other hand, most short interventions have been performed on healthy subjects, such as undergraduate students (e.g., D 'Alonzo, et al, 2004) and sedentary adults (e.g., Sidman, Corbin, & Le Masurier, 2004). Although it is known that even a short pedometer intervention has increased physical activity within one week (Spence, Burgess, Rodgers, & Murray, 2009), this may not have been long enough to increase physical activity in Low and Medium SE groups.…”
