PMID: 16698140;Abstract:
Background & aims: Metabolic carts used in laboratory settings for the measurement of resting metabolism are cumbersome limiting their use in the field. The validity of a newly developed portable calorimeter (Medical Graphics VO2000) under resting conditions was assessed in comparison to a well-established reference system, the DELTATRAC™. Methods: Gas exchange and energy expenditure were measured for 25 min consecutively using the two devices. Values of the last 20 min were averaged and used in the analysis. The order of device for the first subject was randomly chosen and the calorimeters were alternated thereafter. Results: Among 33 subjects, acceptable measures of resting metabolism were obtained in 25 (11 men) aged 20-78 years because eight subjects (three men) either hyperventilated or did not adapt well enough to the facemask. over(V, ̇) O2, over(V, ̇) CO2, and RQ were not significantly different between devices. Small (2.8%) non-clinically relevant mean differences (-0.145±0.341 MJ day-1) were found. Results of the two devices were highly correlated (r=0.95) yielding a more accurate estimate than predictive equations. Conclusions: The VO2000 calorimeter is a valid system to measure resting metabolism but the facemask may not be suitable for some people. © 2006 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Purpose: To determine the annual rate at which physical activity changes in girls during middle school using both objective and self-report measures of physical activity. Methods: Participants were sixth- and eighth-grade girls from the control schools in the Trial of Activity for Adolescent Girls (TAAG). Random cross-sectional samples initially were drawn from sixth-grade girls (n = 786) and 2 years later from eighth-grade girls (n = 1545). A cohort of 501 girls was in both the sixth- and the eighth-grade samples. The girls wore an accelerometer for 6 days and completed the 3-Day Physical Activity Recall. Data were summarized using 3.0-, 4.6-, and 6.5-metabolic equivalent cutpoints for accelerometry and self-reported physical activity. Analyses were performed using repeated-measures analysis of variance in PROC MIXED. Results: More than 40% of the girls were white, approximately 20% were African American, and 20% were Hispanic. The annual percent decrease in physical activity in the cross-sectional sample was approximately 4% (-1.76 min moderate-to-vigorous physical activity/day), using accelerometer data. The percent decrease in physical activity based on self-report data was higher, 6% to 13%, depending on the physical activity variable. Declines tended to be larger in African American girls, but the ethnic differences were not statistically significant. Conclusions: Based on comparisons of cross-sectional samples of sixth- and eighth-grade girls, objectively measured physical activity declined at a rate of 4% per year. © 2009 Society for Adolescent Medicine.
