BACKGROUND: Movement integration (MI) into traditional classroom teaching is a promising opportunity for children to increase physical activity (PA). Education outside the classroom (EOtC) can be regarded as MI, and has increased children's PA in case studies. The aim of this study is to investigate the effects of EOtC on children's PA by segmenting weekly activity-related behavior into a range of day types and domains. METHODS: In a quasi-experimental design, 33 classes were recruited and participants' PA was objectively measured using accelerometers taped to the lower back...

A dominant view in the cognitive neuroscience of object vision is that regions of the ventral visual pathway exhibit some degree of category selectivity. However, recent findings obtained with multivariate pattern analyses (MVPA) suggest that apparent category selectivity in these regions is dependent on more basic visual features of stimuli. In which case a rethinking of the function and organization of the ventral pathway may be in order. We suggest that addressing this issue of functional specificity requires clear coding hypotheses, about object category and visual features, which make contrasting predictions about neuroimaging results in ventral pathway regions...

BACKGROUND: This study examined whether specific worksite supports for physical activity (PA) were associated with total and domain-specific PA. METHODS: A cross-sectional, telephone-based study was conducted in four Missouri, USA, metropolitan areas in 2012 and 2013. Outcome variables included total PA and sub-domains (leisure, work, travel) measured using the International Physical Activity Questionnaire. Logistic regression determined odds of meeting PA recommendations, given access to and use of 18 unique PA worksite supports...

Participation in classroom physical activity (PA) may improve time-on-task (TOT), however, the influence of sustained moderate-to-vigorous PA (MVPA) on TOT is unknown. PURPOSE: To explore the influence of classroom PA delivered with academic lessons on TOT, determine if the relationship between classroom PA and TOT differs by age, sex, race/ethnicity, weight or baseline fitness, and identify the influence of MVPA on TOT when controlling for demographic variables. METHODS: Teachers in intervention schools were asked to deliver two, 10-minute PA lessons/day, 5 days/week...

Multi-voxel pattern analyses (MVPA) are often performed on unsmoothed data, which is very different from the general practice of large smoothing extents in standard voxel-based analyses. In this report, we studied the effect of smoothing on MVPA results in a motor paradigm. Subjects pressed four buttons with two different fingers of the two hands in response to auditory commands. Overall, independent of the degree of smoothing, correlational MVPA showed distinctive patterns for the different hands in all studied regions of interest (motor cortex, prefrontal cortex, and auditory cortices)...

This study sought to determine whether exercise capacity, self-efficacy, and gross motor skills are associated with moderate-to-vigorous physical activity (MVPA) levels in children, and if these associations differ by congenital heart disease (CHD) type. Medical history was abstracted from chart review. We assessed MVPA levels (via accelerometry), percent-predicted peak oxygen consumption ([Formula: see text] cardiopulmonary exercise test), gross motor skill percentiles (test of gross motor development version-2), and self-efficacy [children's self-perceptions of adequacy and predilection for physical activity scale (CSAPPA scale)]...

There is limited evidence examining the association between physical activity (PA), sedentary time (ST), frailty, and factors influencing PA behaviors in migrant older women from ethnically diverse backgrounds. The aims of this mixed-methods study were to: 1) examine PA levels and ST across frailty status; 2) identify any differences in PA/ST between ethnic and religious groups; and 3) qualitatively explore factors influencing PA among older (≥60 years) migrant women (n=60). PA/ST were assessed using accelerometry and frailty status using the frailty phenotype...

Despite physical education's health enhancing potential, students' activity levels in lessons are low. We evaluated a school-based intervention that involved rope skipping on students' moderate-to-vigorous physical activity (MVPA) in physical education. The intervention was evaluated using a clustered randomized controlled trial in 24 classes (N=731 students; M=14.38years; all from Secondary 2) from 12 Hong Kong schools during September to December 2013. The primary outcome was percentage of lesson time spent in MVPA...

OBJECTIVES: Previous studies have indicated that only a small proportion of Portuguese adolescents attain sufficient levels of physical activity for health. However, it is unknown whether the levels of moderate to vigorous physical activity (MVPA) have changed over a considerable time period in this country. Therefore, the aims of the present study were to examine the 10-year trend changes in self-reported MVPA among adolescents and also investigate differences by sex and age. DESIGN AND METHOD: This study compared two cross-sectional cohorts of youngsters aged 12-18 years, recruited in 2006 (N=1010; 461 boys and 549 girls) and in 2016 (N=1096; 461 boys and 635 girls), using identical procedures and instruments...

Active play is a novel approach to addressing low physical activity levels and fundamental movement skills (FMS) in children. This study aimed to determine if a new school-based, 'Go2Play Active Play' intervention improved school day physical activity and FMS. This was a pragmatic evaluation conducted in Scotland during 2015-16. Participants (n = 172; mean age = 7 years) were recruited from seven primary schools taking part in the 5-month intervention, plus 24 participants not receiving the intervention were recruited to act as a comparison group...

Accelerometer-based studies of children's physical activity have reported seasonal patterns in activity levels. However, the inability of many accelerometers to detect activity while the wearer is swimming or cycling may introduce a bias to the estimation of seasonality if participation in these activities are themselves seasonally patterned. We explore seasonal patterns in children's swimming and cycling among a sample of 7-8 year olds (N = 591) participating in the Millennium Cohort Study, UK. Participating children wore an accelerometer for one week on up to five occasions over the year and their parents completed a diary recording daily minutes spent swimming and cycling...

Thorsten Kahnt
Information about potential rewards in the environment is essential for guiding adaptive behavior, and understanding neural reward processes may provide insights into neuropsychiatric dysfunctions. Over the past 10 years, multivoxel pattern analysis (MVPA) techniques have been used to study brain areas encoding information about expected and experienced outcomes. These studies have identified reward signals throughout the brain, including the striatum, medial prefrontal cortex, orbitofrontal cortex, dorsolateral prefrontal cortex, and parietal cortex...
