Effect of ACIVITAL 2-yr-intervention program on screen time, PA and fitness according to weight status and fitness levels in adolescents

  • Presented on May 21, 2014

Purpose: Compared to normal weigh and fit adolescents, overweight and unfit adolescents are more likely to develop cardiovascular disease in adulthood. Despite this, there is insufficient evidence regarding the effectiveness of general schoolbased interventions in these high-risk groups. We assessed if overweight/obese and unfit adolescents responded differently to a ...

SenseCam-coded body positions associated with accelerometer-determined cadence

  • Presented on May 21, 2014

Purpose: To quantify the proportion (%) of time spent in different body positions within incremental bands of accelerometer determined cadence (steps/min). Methods: This was a secondary analysis of SenseCam camera images and ActiGraph GT3X+ accelerometer data concurrently worn during waking hours by 40 adults (70% male; 36±12 years-old; BMI=23±3 kg/m2) for 3...

Mapping schoolyard behavior using GIS, GPS and accelerometers

  • Presented on May 21, 2014

Purpose: To investigate how schoolchildren use different schoolyard areas and whether these areas are associated with different types of behavior. Schoolyard characteristics seem to be related to behavior during recess, but exactly which behavior takes place where is unclear. Methods: Time spent by 316 students (grade 5-8) in 5 types of schoolyard ...

Physical Activity Actigraphy Among Truck Drivers: Accounting for Seat Vibrations

  • Presented on May 30, 2014

Background: Measuring and increasing physical activity among commercial truck drivers is a health imperative due to elevated rates of obesity and associated health problems in the population. However, actigraphy measures of physical activity are likely inflated by large truck seat vibrations during driving periods. Purpose: In preliminary studies recordings ...

Text Messaging: A Tool to Increase Compliance with Physical Activity Interventions?

  • Presented on May 30, 2014

Background: A need exists to identify effective approaches to increase compliance with physical activity interventions conducted in community settings. Purpose: To use accelerometry to analyze the effects of bi-weekly, theoretically based motivational text messages on premenopausal women’s compliance to a walking intervention. Methods: Premenopausal women (n=52, 37.2 ± 6.2 years, 80.8% Caucasian) wore ...
