Journal ArticleDOI
Nonexercise regression models to estimate peak oxygen consumption
TL;DR: It is suggested that N-EX models can be valid predictors of VO2peak for heterogenous samples and stable across the total CV group and various CV subsamples, but not across groups similar in VO2 peak.
Journal ArticleDOI
A method to estimate free-living active and sedentary behavior from an accelerometer.
TL;DR: Compared with the lab-nnet algorithm, Soj-1x and soj-3x improved the accuracy and precision in estimating free-living MET-hours, sedentary time, and time spent in light-intensity activity and MVPA.
Journal ArticleDOI
Validation of the Kaiser Physical Activity Survey in pregnant women.
Michael D. Schmidt,Patty S. Freedson,Penelope S. Pekow,Dawn E. Roberts,Barbara Sternfeld,Lisa Chasan-Taber +5 more
TL;DR: The KPAS is a reliable and reasonably accurate instrument for estimating physical activity among pregnant women and compared with objective and subjective measures of physical activity.
Journal ArticleDOI
Reproducibility of a Self-administered Lifetime Physical Activity Questionnaire among Female College Alumnae
Lisa Chasan-Taber,J. Bianca Erickson,Jeanne W. McBride,Philip C. Nasca,Scott Chasan-Taber,Patty S. Freedson +5 more
TL;DR: The reproducibility of a self-administered physical activity questionnaire designed to assess the duration, frequency, and intensity of lifetime household and recreational activities is assessed and provides a useful measure of average lifetime activity.
Journal ArticleDOI
Multisensor Data Fusion for Physical Activity Assessment
TL;DR: The results demonstrate that the multisensor fusion technique presented is more effective in identifying activity type and energy expenditure than the traditional accelerometer-alone-based methods.
