Abstract:
BACKGROUND: The purpose of this study was to compare the Physical Activity Recall (Stanford 7-days physical activity recall)with the Triaxial accelerometer (RT3)to assess physical activity in young adults. METHODS: Thirty-seven subjects wore the RT3 for 24 hours and then completed the physical activity recall. The Stanford 7-Day Recall records hours of sleep, light-, moderate-, hard-and very hard levels of physical activity. RESULTS: The total energy expenditure per day for the Stanford 7-day recall and RT3 was 2381.29 +/-594.93 kcal/day and 2232.97 +/-398.32 kcal/day,respectively, and showed high correlation (r=0.821).The activity energy expenditure per day for the Stanford 7-day recall and RT3 was 836.21+/-290.59 kcal/day and 509.83+/-181.57 kcal/day,respectively,and showed less high but significant correlation (r=0.327).When compared by sex, the total energy expenditure was significantly correlated in men (r=0.572)and the activity energy expenditure in women (r=0.484). CONCLUSION: The Stanford 7-day recall and the RT3 was highly correlated in the total energy expenditure and significantly correlated in the activity energy expenditure. Therefore,it may be used reciprocally to assess physical activity.
