After-School Activities of Japanese Elementary School Children: Comparison of Children Who Attend Lessons and Cram Schools With Those Who Do Not
Background: This study examined the after-school activities of Japanese elementary school children in which little information is available for understanding the process by which participation in organized activities leads to the decrease in children’s independent mobility. Methods: One thousand eight hundred and twenty-four mothers of elementary school children participated in an online survey. The mothers responded to the questions on the number of lessons (or cram schools) their children attended weekdays, as well as their children’s behavior after classes, and parents providing transportation when their children go out to play. Results: The proportion of children attending lessons and/or cram schools increased as their grades progressed. A significant interaction existed between the degree of parental transportation and grade in terms of whether or not the children attended lessons and/or cram schools. Parental involvement included pick up or drop-off for a large percentage of younger children without lessons, whereas the degree of parental involvement was greater for older children attending lessons. In other words, parents of children without attending lessons or cram schools tended to allow children to engage in independent activities when they reached the higher grades, whereas parents of children who frequently attended lessons and cram schools tended to remain involved in transporting their children, even when they reached the higher grades. Conclusions: The results suggested that the participation of children in organized activities leads to a routine of parental pickup and/or drop-off, which renders difficult the facilitation of opportunities for children to independently participate in play activities.

A Reflective Account of Delivering Multilevel Sport Psychology Support in Professional League of Legends
Matthew Ashford and Laura Swettenham
This case study follows the journey of a trainee sport and exercise psychologist who provided sport psychology support to a top-tier professional League of Legends team across a competitive season. The purpose of this case study is to highlight some of the pertinent professional and contextual demands associated with the process of embedding a three-level (e.g., individual, team, and coach) sport psychology service at the professional level of esports. Specifically, a detailed account of the microprocesses involved in the design and delivery of the sport psychology support is offered along with critical reflections on the lead author’s professional judgments throughout the case in relation to their model of practice and the contextual factors faced. It is hoped that this case study can provide a granular and thoughtful account of how to provide sport psychology support at the professional level in League of Legends.
The KID Study (Kids Interacting With Dogs): Piloting a Novel Approach for Measuring Dog-Facilitated Youth Physical Activity
Colleen J. Chase, Sarah Burkart, and Katie Potter
Background: Two-thirds of children in the United States do not meet the National Physical Activity Guidelines, leaving a majority at higher risk for negative health outcomes. Novel, effective children’s physical activity (PA) interventions are urgently needed. Dog-facilitated PA (e.g., dog walking and active play) is a promising intervention target, as dogs support many of the known correlates of children’s PA. There is a need for accurate methods of quantifying dog-facilitated PA. Purpose: The study purpose was to determine the feasibility and acceptability of a novel method for quantifying the volume and intensity of dog-facilitated PA among dog-owning children. Methods: Children and their dog(s) wore ActiGraph accelerometers with a Bluetooth proximity feature for 7 days. Additionally, parents logged child PA with the family dog(s). Total minutes of dog-facilitated PA and percentage of overall daily moderate to vigorous PA performed with the dog were calculated. Results: Twelve children (mean age = 7.8 ± 2.9 years) participated. There was high feasibility, with 100% retention, valid device data (at least 4 days ≥6-hr wear time), and completion of daily parent log and questionnaire packets. On average, dog-facilitated PA contributed 22.9% (9.2 min) and 15.1% (7.3 min) of the overall daily moderate to vigorous PA for children according to Bluetooth proximity data and parent report, respectively. Conclusions: This pilot study demonstrated the feasibility of utilizing an accelerometer with a proximity feature to quantify dog-facilitated PA. Future research should use this protocol with a larger, more diverse sample to determine whether dog-facilitated PA contributes a clinically significant amount toward overall PA in dog-owning youth.
Physical Behavior Profiles Among Older Adults and Their Associations With Physical Capacity and Life-Space Mobility

We identified data-driven multidimensional physical activity (PA) profiles using several novel accelerometer-derived metrics. Participants aged 75, 80, and 85 (n = 441) wore triaxial accelerometers for 3–7 days. PA profiles were formed with k-means cluster analysis based on PA minutes, intensity, fragmentation, sit-to-stand transitions, and gait bouts for men and women. Associations with physical capacity and life-space mobility were examined using age-adjusted general linear models. Three profiles emerged: “Exercisers” and “actives” accumulated relatively high PA minutes, with actives engaging in lighter intensity PA. “Inactives” had the highest activity fragmentation and lowest PA volume, intensity, and gait bouts. Inactives showed lower scores in physical capacity and life-space mobility compared with exercisers and actives. Exercisers and actives had similar physical capacity and life-space mobility, except female exercisers had higher walking speed in the 6-min walk test. Our findings demonstrate the importance of assessing PA as multidimensional behavior rather than focusing on a single metric.
Policy and Advocacy in Physical Education: Looking Back, Looking Forward
Risto Marttinen and Aaron Beighle
In this paper, we provide an overview of physical education (PE) policy and advocacy research in the United States. We examine the past policy and advocacy work that has been completed in the field and make connections to international policy work. We examine the potential changes the future holds for developing scholarship in the area. We define policy and advocacy and explain how teachers as policy actors are key figures in any policy enacted. The paper also examines the relationship between PE and the public health arena, which completes a lot of PE-focused policy research. The paper concludes with a focus on PE teacher education and the work that higher education must do to help educate future professionals to be advocates for policy change.
Comparison of Sleep and Physical Activity Metrics From Wrist-Worn ActiGraph wGT3X-BT and GT9X Accelerometers During Free-Living in Adults
Duncan S. Buchan
Background: ActiGraph accelerometers can monitor sleep and physical activity (PA) during free-living, but there is a need to confirm agreement in outcomes between different models. Methods: Sleep and PA metrics from two ActiGraphs were compared after participants (N = 30) wore a GT9X and wGT3X-BT on their nondominant wrist for 7 days during free-living. PA metrics including total steps, counts, average acceleration—Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation, intensity gradient, the minimum acceleration value of the most active 10 and 30 min (M10, M30), time spent in activity intensities from vector magnitude (VM) counts, and ENMO cut points and sleep metrics (sleep period time window, sleep duration, sleep onset, and waking time) were compared. Results: Excellent agreement was evident for average acceleration-Mean Amplitude Deviation, counts, total steps, M10, and light PA (VM counts) with good agreement evident from the remaining PA metrics apart from moderate–vigorous PA (VM counts) which demonstrated moderate agreement. Mean bias for all PA metrics were low, as were the limits of agreement for the intensity gradient, average acceleration-Mean Amplitude Deviation, and inactive time (ENMO and VM counts). The limits of agreement for all other PA metrics were >10%. Excellent agreement, low mean bias, and narrow limits of agreement were evident for all sleep metrics. All sleep and PA metrics demonstrated equivalence (equivalence zone of ≤10%) apart from moderate–vigorous PA (ENMO) which needed an equivalence zone of 16%. Conclusions: Equivalent estimates of almost all PA and sleep metrics are provided from the GT9X and wGT3X-BT worn on the nondominant wrist.
