    Abstract
    This study was aimed at evaluating sedentary individuals abilities to recall duration and intensity of moderate physical activity (MPA) before and after an 8-week physical activity intervention. Participants were 41 adults (35 female and 6 male) aged 18-40 years, enrolled in the Tailored Intervention Promoting Physical Activity project, were analyzed through photo recall of physical activity, the International Physical Activity Questionnaire Short Form (IPAQ-SF), and an ActiGraph accelerometer. Paired t-tests were performed to find the mean differences between ActiGraph and self-reported IPAQ-SF MPA before and after photo recall for both pre and post-intervention measurements. The mean differences found between ActiGraph and IPAQ-estimated MPA minutes were not significant (p > 0.05), although ActiGraph minutes were observed to be less than self-reported estimations. Only a marginally significant difference (p = 0.085) was found between after photo recall post-intervention ActiGraph-recorded minutes of MPA and participants’ self-reported minutes, suggesting that participants’ self-reporting accuracy declined after photo recall and intervention. Also, the difference between ActiGraph pre-intervention and post-intervention MPA levels was not significant. ActiGraph-Recorded MPA levels in all participants at pre- and post-intervention were 38.6±21.5 and 37.0±30.0 minutes (p> 0.05), suggesting that the participants did not change their duration of MPA following an 8-week intervention.
