Organizational-Level Factors That Influence Women Coaches’ Experiences
James P. Strode, Heidi M. Parker, and Shannon Kerwin
The purpose of this study was to identify the supports and barriers women coaches experience at the organizational level and to determine how those factors influence interpersonal- and individual-level factors within their coaching context. Nine women who coach high school basketball were interviewed at two time points and asked to reflect on organizational-level factors relative to their coaching position and how those factors have shaped their coaching experience over time. Based on the results of the interviews, two organizational-level factors were identified as barriers for participants: navigating inconsistent hiring practices and hypermasculine culture within school sport. The participants described organizational-level factors as influencing their experiences at both interpersonal (e.g., support from mentors, barriers related to the athletic directors) and individual (e.g., age, experience, sexual orientation) levels. The findings provide empirical support for specific organizational factors that contribute to interpersonal- and individual-level coach experiences. The power structures embedded in these associations are defined and discussed.
Physical Activity and Children’s Episodic Memory: A Meta-Analysis
Daphne G. Schmid, Nathan M. Scott, and Phillip D. Tomporowski
Purpose: The purpose of this review was to evaluate the effects of physical activity on children’s free recall, cued recall, and recognition episodic memory and to explore potential moderating factors. Methods: The following databases were searched: PubMed, ERIC, APA Psych Info, CINHAL, SPORTDiscus, and Google Scholar. Studies were included if: (1) participants were aged 4–18 years, (2) participants were typically developed, (3) participants were randomized to groups, (4) interventions employed gross movements, (5) sedentary group was used for control, (6) memory tests were quantitative, and (7) employed acute or chronic intervention. Results: 14 studies met inclusion criteria resulting in the analysis of data from 7 free recall, 7 cued recall, and 8 recognition memory tests. Physical activity was found to have a positive influence on tests free (g = 0.56), cued recall (g = 0.67), and no influence on tests of recognition (g = 0.06). While some moderator analyses were significant, the authors do not consider these results to be meaningful in application. Conclusions: The effects of acute and chronic physical activity enhance specific aspects of long-term episodic memory. These findings suggest physical activity interventions developed for children may be expected to benefit some, but not all, types of memory processing.
Youths Are Less Susceptible to Exercise-Induced Muscle Damage Than Adults: A Systematic Review With Meta-Analysis
John F.T. Fernandes, Lawrence D. Hayes, Amelia F. Dingley, Sylvia Moeskops, Jon L. Oliver, Jorge Arede, Craig Twist, and Laura J. Wilson
Purpose: This meta-analysis aimed to (1) provide a comparison of peak changes in indirect markers of exercise-induced muscle damage (EIMD) in youths versus adults and (2) determine if the involved limb moderated this effect. Method: Studies were eligible for inclusion if they (1) provided a human youth versus adult comparison; (2) provided data on muscle strength, soreness, or creatine kinase markers beyond ≥24 hours; and (3) did not provide a recovery treatment. Effect sizes (ES) were presented alongside 95% confidence intervals. Results: EIMD exhibited larger effects on adults than in youths for muscle strength (ES = −2.01; P < .001), muscle soreness (ES = −1.52; P < .001), and creatine kinase (ES = −1.98; P < .001). The random effects meta-regression indicated that the effects of upper- and lower-limb exercise in youths and adults were significant for muscle soreness (coefficient estimate = 1.11; P < .001) but not for muscle strength or creatine kinase (P > .05). As such, the between-group effects for muscle soreness (ES = −2.10 vs −1.03; P < .05) were greater in the upper than lower limbs. Conclusion: The magnitude of EIMD in youths is substantially less than in their adult counterparts, and this effect is greater in upper than lower limbs for muscle soreness. These findings help guide practitioners who may be concerned about the potential impact of EIMD when training youth athletes.
Adapted Physical Activity Scholarship: Evolving From Corrective to Inclusion and Anti-Ableist
Karen P. DePauw
Kinesiology and adapted physical activity (APA) share a common history rooted in the medical model approach to physical activity, movement, and the human body. The evolution of APA was influenced by these early roots and later by special-education legislation, sensory-motor perspectives, inclusion movement, and the disability-rights movement. Originally identified as adapted physical education, APA emerged as a professional field and an academic discipline. Since the 1950s, the research and scholarship has increased and cuts across the specialization areas (subdisciplines) of kinesiology. The multidisciplinary nature of APA scholarship has also reached beyond the discipline of kinesiology informed by disability studies and sociology. Reflection about APA and kinesiology reveals the ableist nature of the medical model, which informed early professional practice and scholarship. Thus, it is critical that APA and kinesiology engage in anti-ableist scholarship to better understand human physical activity and movement inclusive of individuals with disabilities.
Adherence to the Singapore Integrated 24-Hour Activity Guidelines by Infants and Toddlers and Its Association With Well-Being
Guan Yuan Loh, Terence Buan Kiong Chua, Kok Hian Tan, Benny Kai Guo Loo, Phaik Ling Quah, and Michael Yong Hwa Chia
Background: This study estimated the prevalence of Singapore infants and toddlers who met the new Singapore Integrated 24-Hour Activity Guidelines for Early Childhood and examined its association with well-being. Methods: A total of 267 parents of children aged between 0 and 2 years completed an online questionnaire that consists of the Singaporean Children Lifestyle Questionnaire and either the Pediatric Quality of Life (PedsQL) Inventory Infant Scale or the Strength and Difficulties Questionnaire. Well-being of infants was measured through parent responses to PedsQL and that of toddlers was measured through Strength and Difficulties Questionnaire. Data were benchmarked against age-specific guidelines for physical activity, screen time, and sleep in the Singapore Integrated 24-Hour Activity Guidelines for Early Childhood. Results: A higher percentage of infants (37.3%) than toddlers (20.6%) had met 3 guidelines. In contrast, a lower percentage of infants than toddlers met at least one or did not meet any guidelines (3.8% and 0% for infants vs 22.4% and 1.8% for toddlers, respectively). Infants who met more guidelines had significantly higher parent-reported PedsQL total scale score than infants who met fewer guidelines (P < .05). However, the present study found that the number of guidelines met was not associated to infants’ PedsQL scale score and toddlers’ total difficulty score (P > .05). Conclusion: Adherence to this set of local guidelines should be widely publicized, so parents will have greater awareness and knowledge on cultivating good physical activity, screen time, and sleep habits for their child from a young age.
Concussion Risk and Recovery in Athletes With Psychostimulant-Treated Attention-Deficit/Hyperactivity Disorder: Findings From the NCAA-DOD CARE Consortium

The aim of the present study was to examine the effects of attention–deficit/hyperactivity disorder (ADHD) –related psychostimulant use in the context of concussion risk and symptom recovery. Data were obtained from the National Collegiate Athletic Association Department of Defense Grand Alliance Concussion Assessment, Research, and Education (NCAA-DOD CARE) Consortium from 2014 to 2017. Relative to individuals without diagnosed ADHD (i.e., control), both ADHD diagnosis and the combination of ADHD diagnosis and psychostimulant use were associated with a greater risk of incurring a concussive injury. Following a concussive injury, ADHD diagnosis was associated with longer symptom recovery time relative to the control group. However, individuals with ADHD who use psychostimulants did not take longer to resolve symptoms than controls, suggesting that psychostimulants may have a positive influence on recovery. Regardless of time point, ADHD diagnosis was associated with an elevated number of concussion-related symptoms; however, this effect appears mitigated by having used ADHD-related psychostimulants.
Entrepreneurial Bricolage and Innovation in Sport for Development and Peace Organizations
Fredrik O. Andersson, Per G. Svensson, and Lewis Faulk
Many sport for development and peace organizations operate with limited resources and in low-resource environments. While resource constraints impede some organizations, others demonstrate an adaptive behavior, known as bricolage, to repurpose and flexibly engage existing resources to accomplish their goals. In this study, we ask what distinguishes organizations that engage in bricolage from others. We specifically test whether sport for development and peace nonprofits that engage in bricolage are more likely to engage in social innovation, and we test those findings against organizational size, age, and characteristics of organizations’ operating environments. Using data from an international sample of 161 sport for development and peace nonprofits, we find that organizations employing greater levels of bricolage also demonstrate significantly higher levels of innovation, except for process-focused innovations, which are significantly associated with environmental turbulence. Organizational size itself does not appear to influence the use of bricolage or the relationship between bricolage and innovation.
The Evolution of Scholarship of Biomechanics and Motor Control Within the Academy: The Past, the Present, and the Future
Kolby J. Brink, Aaron Likens, and Nick Stergiou
This essay delves into the intricate relationship between biomechanics and motor control, exploring their historical evolution and close interdependence. From the foundational works of Aristotle to the contemporary advancements achieved by esteemed members of the National Academy of Kinesiology, we describe the impactful contributions of both past and present National Academy of Kinesiology figures in the realms of motor control and biomechanics. A key theme throughout the essay is the recognition of the fundamental influence of natural laws on movement and the fundamental role of variability in unifying the realms of biomechanics and motor control. Looking ahead, we emphasize the transformative potential of strong inference as a guiding principle for substantive research in both fields, illustrating its application through our investigative endeavors. By uniting biomechanics and motor control through interdisciplinary collaboration, this pursuit of knowledge holds the promise of reshaping our comprehension of human movement and performance.
