Recycling and Resistance to Change in Physical Education: The Informal Recruitment of Physical Education Teachers in Schools
Michelle Elizabeth Flemons, Joanne Hill, Toni O’Donovan, and Angel Chater
Purpose: Physical education (PE) teachers’ interactions with students were explored to examine self-selection for PE teaching as a career option during school. Method: Semistructured life story interviews were conducted with 29 PE teachers at different career stages. Complementing occupational socialization, Bourdieu’s habitus, capital, field, and practice were adopted as thinking tools to inform thematic analysis. Results: Three key themes were identified: (a) acceptance into the inner sanctum based on physical competence, effort, and enthusiasm for the traditional curriculum; (b) opportunities provided to students accepted into the inner sanctum, and (c) outside the inner sanctum: mismatched habitus and self-selection for PE teaching. Conclusion: Students exchanged competence, effort, and enthusiasm in the traditional curriculum for acceptance and opportunities to encourage self-selection for teaching PE. Without acceptance, individuals experienced challenges gaining career support. Dominated by a homogenous group resistant to change, PE needs independent careers information to promote change through heterogeneity.
Psychometric Properties of a Modified Athlete Burnout Questionnaire in the Collegiate Athletics Setting
Madeline P. Casanova, Ashley J. Reeves, and Russell T. Baker
Context: Mental health is an important component of holistic care in athletic settings. Burnout is one of many factors associated with poor mental health, and clinicians should assess for these symptoms. The Athlete Burnout Questionnaire (ABQ) has been proposed as a measure of burnout in athletes; however, design concerns are prevalent within the scale, and psychometric analyses have resulted in inconsistent measurement properties, limiting the usefulness of the scale for accurate assessment of burnout in athletes. The objective of our study was to assess the factor structure of the Alternate Modified ABQ-15v2 using confirmatory factor analysis. If model fit was inadequate, a secondary purpose was to identify a psychometrically sound alternate ABQ model. Design: Observational study. Methods: Intercollegiate athletes and dancers pursuing a degree in dance (n = 614) were recruited from programs across the United States. Individuals had varied health statuses (eg, healthy, injured), scholarship support, and participated in a variety of intercollegiate sports. A confirmatory factor analysis was conducted on the modified 15-item ABQ (Alternate Modified ABQ-15v2). Exploratory factor analysis and covariance modeling of a proposed alternate 9-item scale (ABQ-9) was conducted and multigroup invariance analysis was assessed across athlete category, class standing, and student-athlete scholarship status to assess consistency of item interpretation across subgroups. Results: The Modified ABQ did not meet recommended model fit criteria. The ABQ-9 met all recommended model fit indices but was not invariant across athlete category. Conclusions: The ABQ-9 may be a viable and efficient option for assessing burnout in the collegiate athletics setting. However, further research is needed to validate the ABQ-9 in a cross-validation study.
Influencers de la Educación Física en Instagram: el Engranaje entre Conocimiento Experto, Estrategias de Microcelebridad y Funcionalidades de la Plataforma
Alejandro Alcolea Lozano and Maria José Camacho-Miñano
Purpose: This study analyses the role of Physical Education (PE) teachers who are influencers on the Instagram social network. Method: Using a descriptive case study, the profiles of three Spanish PE influencers were analysed for seven months (159 posts and 73 stories) with a thematic analysis. Results: The results show that the PE influencer is the product of a complex interplay in which the dissemination of their knowledge and their identity as experts is developed through microcelebrity strategies and the management of the functionalities of the platform itself aimed at boosting their visibility and, ultimately, monetising their content. Conclusion: It concludes with the tensions that exist for PE around this phenomenon within the neoliberal educational context and the need for teacher training to be adapted to this new educational reality.
Predictors of Physical Activity Levels in Ambulant/Semiambulant Children and Adolescents With Cerebral Palsy: A Clinical Cohort Study
Christina Esmann Fonvig, Jens Troelsen, Jan Christian Brønd, Sören Möller, and Anders Holsgaard-Larsen
Children and adolescents with cerebral palsy (CP) show a reduced physical activity (PA) level compared with their typically developed peers. This study aimed to identify potential predictors of objectively evaluated habitual PA using data from a national clinical registry—the Cerebral Palsy Follow-Up Program (CPFP)—and proxy-reported questionnaires. Data from the CPFP database showed that female sex was associated with a lower PA level. Additional questionnaire data revealed age, popliteal angle limitation, Pediatric Outcomes Data Collection Instrument–Sports and Physical Functioning Scale score, screen time, Functional Mobility Scale score at 50 m, and fatigue as predictors. The proposed models can be used for the prediction and early detection of the PA level and consequently for the potential improvement among ambulant/semiambulant individuals with CP. Further research should investigate the predictive impact of personal, social, and environmental factors on the PA level and the gap in PA levels between girls and boys.
Differences in Older Adults Walking Football Initiation and Maintenance Influences Across Respondent Characteristics: A Cross-Sectional Survey
Rachel Cholerton, Joanne Butt, Helen Quirk, and Jeff Breckon
Despite health benefits gained from physical activity and sport participation, older adults are less likely to be active. This study investigates what influences 50- to 75-year-olds (N = 439) to initiate and maintain walking football, across gender, socioeconomic status, number of health conditions, and physical activity level. It also considers relationships between participant characteristics and influences, and intentions to play after a forced break (COVID-19). Results of a U.K. online cross-sectional survey found those with two or more health conditions rated social influences significantly higher in initiation and maintenance than participants with no health conditions. Multiple regression analysis found a positive walking football culture, and perceived use of maintenance resources contributed significantly to intentions to return to play after COVID-19 restrictions eased. Practitioners should consider providing opportunities for social connection, foster a positive walking football culture, and encourage players to utilize maintenance resources (e.g., scheduling sessions) in older adult walking football sessions.
Assessment of RPE Signal Dominance at Slow to Moderate Walking Speeds in Children

The purpose of this investigation was to determine whether either the differentiated ratings of perceived exertion (RPE) for the legs (RPE-L) or chest (RPE-C) were higher than the overall body RPE (RPE-O) in children performing treadmill walking. A differentiated RPE that was higher than the RPE-O was considered the dominant perceptual signal. Thirty-one 10-year-old participants (16 boys, 15 girls) performed six separate 5-min bouts of level treadmill walking at different speeds. During each bout of exercise, RPEs were recorded using the modified Children’s OMNI Scale. Oxygen consumption (VO2), heart rate (HR), and ventilation (VE) were measured during Minutes 4 and 5 at each walking speed. VO2, HR, and VE increased as walking speed increased, as did perceived exertion. No differences were observed among RPE-O, RPE-L, and RPE-C at any speed. In addition, boys and girls exhibited similar responses for each perceptual and physiological variable. In conclusion, a dominant differentiated perceptual rating was not found at slow-to-moderate treadmill walking speeds for either boys or girls. Neither the respiratory–metabolic nor peripheral ratings of perceived exertion appeared to dominate the whole-body sensory-integration process in this sample.
Park Area and Physical Activity Among Children and Adolescents: Findings From the Healthy Communities Study
Matthew T. Stewart, Manish Verma, Alisha Rajbhandari, Cathy L. Antonakos, and Natalie Colabianchi
Background: There is currently a nationwide effort to bring parks and green spaces within a 10-minute walk of the home. We examined the association between park area within 1 km of a child’s residence and self-reported park-specific physical activity (PA) along with accelerometer-derived moderate to vigorous physical activity (MVPA). Methods: A subsample of K through eighth-grade youth (n = 493) from the Healthy Communities Study reported whether they engaged in park-specific PA during the last 24 hours and wore an accelerometer for up to 7 days. Park area was defined as the percentage of park land in a 1 km Euclidean buffer around the participant’s residence, categorized into quintiles. Analysis consisted of logistic and linear regression modeling with interaction effects that controlled for clustering within communities. Results: Regression models estimated greater park-specific PA for participants in the fourth and fifth quintiles of park land. Age, sex, race ethnicity, and family income were unrelated to park-specific PA. Accelerometer analysis indicated that total MVPA was unrelated to park area. Older children (β = −8.73, P < .001) and girls (β = −13.44, P < .001) engaged in less MVPA. Seasonality significantly predicted both park-specific PA and total MVPA. Conclusion: Increasing park area is likely to improve youth PA patterns, lending support for the 10-minute walk initiative.
Reliability and Sensitivity of Nocturnal Heart Rate and Heart-Rate Variability in Monitoring Individual Responses to Training Load
Olli-Pekka Nuuttila, Santtu Seipäjärvi, Heikki Kyröläinen, and Ari Nummela
Purpose: To assess the reliability of nocturnal heart rate (HR) and HR variability (HRV) and to analyze the sensitivity of these markers to maximal endurance exercise. Methods: Recreational runners recorded nocturnal HR and HRV on nights after 2 identical low-intensity training sessions (n = 15) and on nights before and after a 3000-m running test (n = 23). Average HR, the natural logarithm of the root mean square of successive differences (LnRMSSD), and the natural logarithm of the high-frequency power (LnHF) were analyzed from a full night (FULL), a 4-hour (4H) segment starting 30 minutes after going to sleep, and morning value (MOR) based on the endpoint of the linear fit through all 5-minute averages during the night. Differences between the nights were analyzed with a general linear model, and intraclass correlation coefficient (ICC) was used for internight reliability assessments. Results: All indices were similar between the nights followed by low-intensity training sessions. A very high ICC (P < .001) was observed in all analysis segments with a range of .97 to .98 for HR, .92 to .97 for LnRMSSD, and .91 to .96 for LnHF. HR increased (P < .001), whereas LnRMSSD (P < .01) and LnHF (P < .05) decreased after the 3000-m test compared with previous night only in 4H and FULL. Increments in HR (P < .01) and decrements in LnRMSSD (P < .05) were greater in 4H compared with FULL and MOR. Conclusions: Nocturnal HR and HRV indices are highly reliable. Demanding maximal exercise increases HR and decreases HRV most systematically in 4H and FULL segments.
