Abstract
The purpose of this investigation was to compare and evaluate five different methods of physical activity assessment in a group of adult females, aged 20 to 65 years. Perceived physical activity was obtained by completion of self- and interviewer-administered seven-day activity recall surveys. Within three weeks, self report diary and motion sensing accelerometer data were collected during three days of free-living physical activity. Simultaneously, heart rate was continuously monitored during one of these days and dietary intake was recorded all three days. Measurements of resting heart rate and blood pressure, body stature and mass, and hydrostatic weighing estimate of percent body fat were obtained. Heart rate index (daily average heart rate/resting heart rate) was the heart rate variable which best reflected the physical activity presented by the other methods. The subjective assessment methods had better agreement among themselves than with objective instruments, while the association between mechanical devices of was lower yet. All methods except the self-administered questionnaire distinguished between activity groups and were inversely related to body fatness and lower resting heart rate and directly related to caloric intake. The multidimensional physical activity behavior appears to be evaluated best by using survey procedures in combination with objective mechanical tools. The interview questionnaire, diary, accelerometer and heart rate index were effective in assessing physical activity.
