McCormack, Gavin R.; Rutherford, Jack; Giles-Corti, Billie; Tudor-Locke, Catrine; Bull, Fiona – Research Quarterly for Exercise and Sport, 2011
The purpose of this study was to establish sex-specific criterion-referenced standards for pedometer-determined physical activity related to body mass index (BMI)-defined weight status among youth. We analyzed data from 7-16-year-old boys (n = 338) and girls (n = 337) and used pedometer-assessed physical activity and anthropometric data to derive…

Hart, Teresa L.; Brusseau, Timothy; Kulinna, Pamela Hodges; McClain, James J.; Tudor-Locke, Catrine – Research Quarterly for Exercise and Sport, 2011
This study compared step counts detected by four, low-cost, objective, physical-activity-assessment instruments and evaluated their ability to detect moderate-to-vigorous physical activity (MVPA) compared to the ActiGraph accelerometer (AG). Thirty-six 10-11-year-old children wore the NL-1000, Yamax Digiwalker SW 200, Omron HJ-151, and Walk4Life…

van der Ploeg, Hidde P.; Tudor-Locke, Catrine; Marshall, Alison L.; Craig, Cora; Hagstromer, Maria; Sjostrom, Michael; Bauman, Adrian – Research Quarterly for Exercise and Sport, 2010
The single most commonly reported physical activity in public health surveys is walking. As evidence accumulates that walking is important for preventing weight gain and reducing the risk of diabetes, there is increased need to capture this behavior in a valid and reliable manner. Although the disadvantages of a self-report methodology are well…

Tudor-Locke, Catrine; McClain, James J.; Hart, Teresa L.; Sisson, Susan B.; Washington, Tracy L. – Research Quarterly for Exercise and Sport, 2010
As researchers and science writers, the authors are always pleased when anyone takes enough interest in their work, but this time it was especially pleasing to have inspired Beets to comment on it (Beets, 2010)! The focus of his commentary is "Expected Values for Pedometer-Determined Physical Activity in Youth" (Tudor-Locke, McClain, Hart, Sisson,…

Tudor-Locke, Catrine; McClain, James J.; Hart, Teresa L.; Sisson, Susan B.; Washington, Tracy L. – Research Quarterly for Exercise and Sport, 2009
The purpose of this review is to integrate and summarize specific measurement topics (instrument and metric choice, validity, reliability, how many and what types of days, reactivity, and data treatment) appropriate to the study of youth physical activity. Research quality pedometers are necessary to aid interpretation of steps per day collected…

Tudor-Locke, Catrine; McClain, James J.; Hart, Teresa L.; Sisson, Susan B.; Washington, Tracy L. – Research Quarterly for Exercise and Sport, 2009
This review assembles pedometry literature focused on youth, with particular attention to expected values for habitual, school day, physical education class, recess, lunch break, out-of-school, weekend, and vacation activity. From 31 studies published since 1999, we constructed a youth habitual activity step-curve that indicates: (a) from ages 6…

Kang, Minsoo; Bassett, David R.; Barreira, Tiago V.; Tudor-Locke, Catrine; Ainsworth, Barbara; Reis, Jared P.; Strath, Scott; Swartz, Ann – Research Quarterly for Exercise and Sport, 2009
This study was designed to determine the number of days of pedometer monitoring necessary to achieve reliable and valid estimates of a 1-year average of step counts in adults based on either consecutive days (CD) or random days (RD) of data collection. Twenty-three participants (16 women; M age = 38 years, SD = 9.9) wore a Yamax SW 200 pedometer…

Tudor-Locke, Catrine; Ainsworth, Barbara E.; Popkin, B. M. – Research Quarterly for Exercise and Sport, 2008
This is a repeated cross-sectional study of overweight and physical activity (PA) and inactivity patterns of successive samples of 7-13-year-old Russian children who were surveyed six times between 1995 and 2002 as part of the Russian Longitudinal Monitoring Survey. This analysis focused on moderate/vigorous (MOD/VIG) PA (e.g., active commuting to…

Felton, Gwen M.; Tudor-Locke, Catrine; Burkett, Lee – Research Quarterly for Exercise and Sport, 2006
This study examined stability and reliability of free-living physical activity assessed by pedometer in 69 young female college students (M age = 18.7 years, SD = 1.2, range: 18-25 years; body mass index = 23.2 kg/m[superscript 2], SD = 0.6) for two complete weeks (Week 1 and Week 2) separated by 12 weeks. During Week 1, participants took an…

Flohr, Judith A.; Todd, M. Kent; Tudor-Locke, Catrine – Research Quarterly for Exercise and Sport, 2006
The purpose of this study was to evaluate the physical activity (PA) patterns of children. Forty-four 7th-grade students (19 boys, 25 girls) recorded pedometer data for 2 consecutive weeks. Separate 2 x 3 repeated measures analyses of variance were used to examine differences in total steps/day between boys and girls and between after-school…

Ainsworth, Barbara E.; Tudor-Locke, Catrine – Research Quarterly for Exercise and Sport, 2005
In the past 75 years, articles in Research Quarterly for Exercise and Sport (RQES) have contributed to the understanding of the role physical activity plays in the health of individuals and populations. Articles have described laboratory and community research studies in humans and animals, presented reviews of topics and conference proceedings,…

Tudor-Locke, Catrine – Research Quarterly for Exercise and Sport, 2001
Evaluated the effectiveness of a physical activity log and a pedometer with respect to responsiveness to change in a walking program. Obese and sedentary adults monitored their physical activity over time using both methods concurrently. The log did not detect increases in physical activity that were detected by pedometer. The pedometer was simple…
