The Physical Activity Questionnaires (PAQ-Children and PAQ-Adolescents) are widely used to assess youth physical activity patterns but a limitation is that they do not provide information about time spent in moderate-to-vigorous physical activity (MVPA). Purpose The purpose of this study was to calibrate in- and out-of-school activity items of the ...
Purpose To examine the accuracy of three measurement devices (ActiGraph GT3x+, ActivPAL, and Sensewear Armband) in assessing sedentary behavior and light-intensity physical activity (PA) against a referent measure of oxygen uptake (Oxycon Mobile). Methods 16 adults (8 males, 8 females) wore the four measurement devices while performing 7 activities (walking at 1.0 mph, 1.5 mph, 2.0 ...
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 ...
The International Physical Activity Questionnaire (IPAQ) is one of the most widely used questionnaires to assess physical activity (PA). Validation studies for the IPAQ have been executed, but still there is a need for studies comparing absolute values between IPAQ and accelerometer in large population studies. Purpose: To compare PA ...
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 ...
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 ...
Introduction In México, despite the important issue of obesity and overweight, little is known regarding the relationship of physical activity and their related health issues, especially in the adolescent population Purpose To evaluate in a group of sophomore high school students the amount of physical activity measured by accelerometry ...
