Parental Knowledge of Physical Activity Recommendations and the Ability to Assess Their Child’s Physical Activity

  • Presented on May 30, 2013

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). ...


Relationship Between Sleep and Next Day Physical Activity

  • Presented on May 30, 2013

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 ...


Accelerometer Technologies, Specifications, and Limitations: A presentation by ActiGraph at ICAMPAM 2013

  • Presented on June 17, 2013

Introduction Technology advances and manufacturing efficiency improvements have drastically increased the options and flexibility available to users of accelerometer-based products. These advancements have led to confusion among activity monitor users, and many have been led to believe that device output normalization is an obvious and easy step. In truth, there ...


Recognizing Physical Activity Patterns Individually Using Hidden Markov Models

  • Presented on May 31, 2013

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 ...


Development of a New Cell Phone-Based Physical Activity Recall Using Daily Activity Pictures

  • Presented on May 31, 2013

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 ...


Use of Objective Measures to Estimate Sedentary Time in Youth

  • Presented on May 31, 2013

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 ...


Physical Activity, Executive Function, and School Readiness in Young Children

  • Presented on May 31, 2013

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 ...


Relationship Between Physical Activity Patterns And Key Cardiopulmonary Exercise Testing Variables In Patients With Heart Failure

  • Presented on May 31, 2013

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 ...


Evaluation of an Unstructured Afterschool Physical Activity Program

  • Presented on May 31, 2013

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 ...


Contribution of Active Video Game Play to Daily Physical Activity among College Students

  • Presented on May 31, 2013

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 ...
