Assessing physical activity: The weekly physical activity log (RSAF)

The aim of this study was to propose the Weekly Physical Activity Log (RSAF in Spanish) to assess physical activity behaviour in adults. To this end, 132 adults (mean = 28.53 years; SD = 11.20) completed the RSAF. The energy expenditure (METs) of daily physical activities was obtained for a week and the percentile scores were calculated in terms of gender and age. The energy expenditure data were compared with the physical activity level and measures of fitness. The results show that active participants tend to have higher energy expenditure level than non-active participants, and the correlation between aerobic fitness and average weekly energy consumption is significant. These results show that the RSAF is useful and suitable for assessing daily physical activity and fitness in adults.
