Various sets of prediction equations for the Actigraph have been developed to estimate energy expenditure (EE) in youth, but there is no consensus about the best approach. A set of two 2-regression models (2RM) have been proposed as alternative to traditional single regression models (1RM), but they have not been ...
Little research exists assessing parent and child physical activity (PA) in relation to parental knowledge of PA recommendations. Purpose To subjectively and objectively assess parent and child PA and parental knowledge of the moderate-to-vigorous physical activity (MVPA) guidelines for adults and children. Methods Participants were 20 parent-child pairs (child age 8.9 ± 1.9 y). ...
Objective The purpose of this study was to examine the effect that sleep duration and quality has on next day physical activity among a population of young adult women. Subjects: Three-hundred and seventy-five women (18-24 yrs) were recruited to participate in the study. Measurements Each participant wore an accelerometer for 7 ...
Accelerometers offer valid and objective measures to assess free-living physical activity (PA) (Kodama et al, 2002; Lyden et al, 2012). While these devices provide rich information with frequent readings over a period of time, the large amount of data is difficult to analyze and special techniques to extract features are needed. Summarizing ...
Purpose Self-reported physical activity (PA) has several challenges, including recall errors, social desirability, incomplete answers and misunderstanding of questionnaires. All of these affect PA estimates. To reduce recall errors, daily PA diaries have been used as a criterion for other types of PA questionnaires. The purposes of this study were ...
Purpose The purpose of this study was to examine the use of the ActivPAL (AP) and ActiGraph GT3X (AG) for estimating SB during structured and free-living physical activity (PA) in youth. Methods Twenty-nine boys and 23 girls (mean±SD; age, 12±0.9 yrs; BMI 23.3±5.8 kg.m-2) performed up to 8 structured activities and ...
Moderate-to-vigorous physical activity (MVPA) and executive function (EF), the ability to organize thoughts and make decisions, have been identified as contributors to cognitive ability and academic success in school-aged children. These associations have not been established in young children. Purpose To determine the influence of MVPA and EF on school ...
Purpose A hallmark characteristic of heart failure (HF) is reduced physical activity (PA) patterns and functional capacity. The relationship between key cardiopulmonary exercise testing (CPX) variables and PA patterns has not been investigated. To evaluate PA patterns in patients with ischemic HF and its relationship to peak oxygenconsumption (VO2), the ...
Purpose To evaluate an unstructured afterschool physical activity (PA) program for elementary school students. Methods PA levels of 3rd, 4th, and 5th grade students (N=205) at four lowincome elementary schools (67-79% free and reduced lunches) were cross-sectionally assessed during an unstructured afterschool PA program. Assessments at each school were conducted ...
National surveys indicate less than half of college-age students meet physical activity (PA) guidelines (ACHA, 2009). Additionally, 65% of college students are active video game (AVG) players (Jones, 2003). AVGs incorporate PA into game play and could be used to increase PA. A key step in establishing their efficacy as an intervention tool ...
