Publication Summary
1 (57,619±32,217) to week 12 (79,381±30,111) (p<0.000). This increase in step counts was strongly correlated to an increase in both temperature (r=.742; p=0.006) and daylight hours (r=0.738; p=.006). From the post-program questionnaire, participants reported that lack of time (78%) and poor weather (28%) were significant barriers to obtaining regular physical activity. CONCLUSIONS: Temperature and daylight hours had a moderate, positive correlation with physical activity during the fall semester and a strong, positive correlation with physical activity during the spring semester. Future walking interventions should address these perceived barriers by educating and motivating participants to stay physically active especially during colder seasons with fewer hours of daylight.
