Mindfulness meditation (MM) has decreased kinesiophobia in patients with knee pathologies. Mobile application-delivered MM (Mobile MM) may reduce kinesiophobia in individuals after anterior cruciate ligament reconstructions (ACLR). The purpose of this study was to examine the feasibility (i.e., retention, adherence, and acceptability) and preliminary efficacy of a 4-week Mobile MM intervention in individuals with a history of ACLR. Nine participants ≥1 year post unilateral ACLR completed 12 sessions of Mobile MM over 4 weeks via the Headspace mobile application that were facilitated remotely through a Health Insurance Portability and Accountability ACT of 1996 (HIPAA) compliant teleconference system. Participant retention of 100% and intervention adherence of 100% were observed. Participants reported moderate to high acceptability for the Mobile MM. A large between-group effect size of 1.6 [0.13, 2.98] in the Tampa Scale of Kinesiophobia-11 change score was observed. Mobile MM is a feasible intervention to address kinesiophobia in individuals with a history of ACLR.

Neurocognitive Hop Performance in Patients With Chronic Ankle Instability
Ji Yeon Choi, Colleen Vogel, Christopher J. Burcal, Lindsey E. Remski, Brian A. Knarr, and Adam B. Rosen
The purpose of this study was to determine differences in neurocognitive hop function among individuals with chronic ankle instability, ankle sprain copers, and control participants and identify the relationship between the self-reported function and neurocognitive hop performance; 61 participants across control, ankle sprain coper, and chronic ankle instability groups completed the Cumberland Ankle Instability Tool and the Choice-Reaction Hop Test. There was no significant difference in neurocognitive hop performance among groups. However, there was a large correlation between the Cumberland Ankle Instability Tool and the Choice-Reaction Hop Test. Those with chronic ankle instability with worse self-reported disability concurrently demonstrated decreased performance during the Choice-Reaction Hop Test, reflecting poorer neurocognitive hop performance.
State-Level Politics and Bias Predict Transgender Athlete Bans
Kelsey M. Garrison and George B. Cunningham
The purpose of this study was to examine the relationships among the political leanings of a state, the state-level implicit and explicit biases against transgender people, and the presence of transgender athlete bans. The authors collected archival data from 2021 and 2022 bans in the United States to examine the hypotheses. As of 2022, 18 states had passed laws barring transgender athletes from participating in sports. Results from regression analyses showed that conservative-leaning states were more likely to enact transgender athlete bans than their peers. The relationship was mediated by explicit (but not implicit) bias toward transgender people. The findings have implications for research and practice. Sport managers have an opportunity to create transgender-inclusive workplaces for staff, coaches, and other managers. They should also work with campus counselors and other staff to ensure that transgender athletes have ample support.

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.

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.
