- W2051265112 abstract "PURPOSE: This study compared measures of physical activity (PA) taken from the 7-day Physical Activity Recall (PAR) and the International Physical Activity Questionnaire(IPAQ) with those obtained from the NL 2000 (NL) and Lifecorder (LC) accelerometersin entering, college freshmen. METHODS: 47 males and 64 females (overall age =18.5±.3 yrs, wt. = 68.7±14.4 kg, andBMI = 23.7 ±4.9) volunteered and signed an informed consent form. All subjects worethe NL for 7 days, and half wore the LC as well. After the 7 days the subjects completedthe PAR and IPAQ. RESULTS: There was a strong agreement between accelerometers with PAEE expressedin kcal/wk (r = 0.958, p= 0.000). However, the NL recorded significantly higher values(p= 0.0001) for PAEE than the LC (Md= 2705 vs. 2120). Both PAR kcal/wk and IPAQkcal/wk were significantly related to the NL kcal/wk, r = 0.275 (p= 0.004) and r= 0.430(p= 0.000), respectively. In addition, there were no significant differences in overallPAEE between the NL and PAR (p= 0.148) or the NL and IPAQ (p= 0.198). However,both the PAR and IPAQ reported more PAEE as energy expenditure exceeded 3000kcal/wk. PAR moderate and vigorous MET-min/wk were not significantly related to LCmoderate (p= 0.411) and vigorous MET-min/wk (p= 0.204), respectively. In addition,there were significant differences in MET-min/wk between the PAR and LC for moderate(p= 0.019) and vigorous (p= 0.000) activity. PAR reported relatively the same PAEE atlower amounts of moderate intensity exercise, but reported more PAEE as energyexpenditure increased. PAR systematically reported more vigorous PAEE across the fullrange of energy expenditure. CONCLUSION: The accelerometers correlated highly and were in close agreement withone another. In first year freshmen, both surveys provided overall estimates of PAEE thatwere significantly related to objective measures of PA. However, at high levels of energyexpenditure, the questionnaires captured more of the vigorous PA that the accelerometerscould not monitor." @default.
