Background: The associations between mobility limitations and device-measured physical activity are sparsely studied. In this study, these associations are studied among community-dwelling older twins. Methods: This cross-sectional study utilized data gathered in 2014–2016 for the MOBILETWIN study. Participants were twins born in Finland between 1940 and 1944 (774 participants, mean age 73 years). Physical activity was measured with a hip-worn accelerometer. Mobility limitations were assessed with a questionnaire. Results: Individual-level analyses revealed that physical activity was associated with mobility limitations. Participants with severe mobility limitations took 2,637 (SD = 1,747) steps per day, those with some mobility limitations 4,437 (SD = 2,637) steps, and those without mobility limitations 7,074 (SD = 2,931) steps (p < .05). The within-twin pair analyses revealed the same pattern for the 144 dizygotic twin pairs, but no associations were seen for the 117 monozygotic twin pairs. Conclusions: Accelerometer-measured physical activity and mobility limitations were associated in community-dwelling older adults. Genetic factors may explain some of the variations in physical activity. Significance: A personalized exercise program to promote increased physical activity should be provided for older adults who report mobility difficulties. Future research is needed to examine causality between physical activity and mobility limitations.

Background: The association of working from home (WFH) with physical activity (PA) and sedentary behavior (SB) has been explored; however, this association during periods without stringent measures to combat coronavirus disease 2019 is undercharacterized. Particularly, few studies have evaluated the potential effect modification on its associations. Therefore, this study aimed to investigate the associations of WFH frequency with accelerometer-measured PA and SB, along with its effect modifiers, among Japanese white-collar workers during the later pandemic period. Methods: A cross-sectional study involving 1133 white-collar workers residing in the Tokyo metropolitan area was conducted between April 2022 and March 2023. WFH frequency was evaluated through a self-report questionnaire, while SB and PA during weekdays were measured using a triaxial accelerometer. Linear regression models adjusting for potential confounders were used to examine the association of WFH frequency with PA and SB. Results: Regardless of activity intensity, individuals who worked at home, even for 1 to 2 days per week, demonstrated lower levels of PA and higher levels of SB as compared with those who did not (P < .05). For example, difference between never and ≥5 days per week WFH was approximately 70 minutes/day for total PA and about 4000 steps/day for step counts. Associations between WFH and decreased PA were more pronounced in workers who were older, female, less educated, in sales and service work, nonregular staff, and precontemplating changes in exercise and eating habits. Conclusions: We report that WFH was associated with decreased PA and increased SB in Japanese white-collar workers with pronounced associated in several subgroups.
Context, Climate, and Red Tape: Considerations for Social-Justice Curriculum Development in Kinesiology
Karen Lux Gaudreault, Victoria Shiver, Martin Vasquez, Sean Fullerton, and Luis Sanchez Martinez
Curricula grounded in social justice are vital in higher education, including kinesiology programs. The United States has seen continued increases in diversity, with education consistently displaying poor representation of historically marginalized groups. The purpose of this paper is to offer three elements that kinesiology programs should consider when aiming to successfully engage in developing social-justice curricula: context, climate, and “red tape.” We define and describe each element and how it influences our approach to curriculum development and provide specific examples from our work in the University of New Mexico Physical Education Teacher Education program to illustrate practical implementation. We argue that social-justice curriculum development is required to prepare young professionals to enter the field with the knowledge, skills, and dispositions to meet the needs of diverse communities.
Epidemiological Study of Track-and-Field Meets On-Field Medical Care
Yosuke Hiroshige, Hodaka Watanabe, Shinji Tomiyama, and Hajime Kato
Background: Most epidemiological studies on track-and-field meets have been limited to the Olympics and world championships. These are meets in which only high-performance athletes participate at a certain time of the year. In contrast, epidemiological studies on athletes of various ages and across different seasons may provide health care providers with valuable insights into injury prevention and on-field medical care. The study aims to determine the trends and locations of injuries during track-and-field meets in athletes of various ages and seasons based on on-field medical care records. Methods: The number and incidence of injuries requiring on-field medical care during or after the event were obtained from 39 track-and-field meets. Injuries were defined as cases that required on-field medical care. The incidence was defined as the number of injuries per 1000 athlete exposures wherein 1 athlete exposure is the athlete’s participation in one event. We also recorded the number of injuries at each location and whether transportation to a medical station was required. Results: A total of 191 injuries were reported. This study identified a population with a high incidence of injury (middle- and long-distance events, combined events, and athletes over the age of 19), areas within the stadium where injuries were more likely to occur (finish line and first turn), and a high rate of transport to the medical station (approximately 70%); most of them were transported to wheelchairs. Conclusion: The results provide insights into the trends, locations, and transport of injured athletes during track-and-field meets. Professionals will better understand the injuries occurring during track-and-field meets and can improve the efficiency of on-field medical care activities. They will also assist organizers in track-and-field meets to improve the safety of their meet operations.
Modern Pain Science and Alexander Technique: How Might Alexander Technique Reduce Pain?
Mari Hodges, Rajal G. Cohen, and Timothy W. Cacciatore
This article brings together research from the fields of pain science and Alexander Technique (AT) to investigate the mechanisms by which AT helps reduce pain. AT is a cognitive embodiment practice and a method for intentionally altering habitual postural behavior. Studies show that AT helps with various kinds of pain, although the mechanisms of pain reduction are currently not well understood. Advances in pain science may give insight into how this occurs. Modern interventions with efficacy for improving pain and function are consistent with active approaches within kinesiology. They also share similarities with AT and may have common mechanisms such as learning, mind–body engagement, normalization of sensorimotor function, improvement of psychological factors, and self-efficacy, as well as nonspecific treatment effects. AT likely has additional unique mechanisms, including normalization of muscle tone, neuronal excitability, and tissue loading, as well as alterations to body schema, attention redirection, and reduction in overall reactivity.

Diego Augusto Santos Silva, Salomé Aubert, Taru Manyanga, Eun-Young Lee, Deborah Salvo, and Mark S. Tremblay
Background: The World Health Organization recognizes that physical activity (PA) during childhood is crucial for healthy development, aligning well with the achievement of several United Nations (UN) Sustainable Development Goals (SDGs). This study aimed to explore the associations between 10 key indicators of PA for children and adolescents assessed in the Global Matrix 4.0 project, and the UN SDGs. Methods: Data from 57 countries/jurisdictions of the Global Matrix 4.0 project were used. The UN SDG indicators were sourced from the SDG Transformation Center, which publishes each country’s performance on each of the 17 SDGs. Given the robust evidence supporting plausible links between PA and SDGs 3 (good health and well-being), 9 (industry, innovation, and infrastructure), 11 (sustainable cities and communities), 13 (climate action), and 16 (peace, justice, and strong institutions), these SDGs were investigated. Results: Countries/jurisdictions with good and moderate performance in achieving SDG 3, SDG 9, SDG 11, and SDG 16 had higher grades than countries/jurisdictions with fair performance in achieving these SDGs for the following indicators: Organized Sports and PA, Community and Environment, and Government Investments and Strategies. However, countries/jurisdictions with good performance in achieving SDG 13 had lower grades than countries/jurisdictions with fair performance in achieving SDG 13 for the following indicators: Organized Sports and PA, Community and Environment, and Government Investments and Strategies. Conclusions: Organized Sports and PA, Community and Environment, and Government Investments and Strategies were the indicators that demonstrated differences between countries/jurisdictions with good and poor performance in achieving the SDGs.
Tracing the Pioneers: Ballroom Dance Instructors and “Taxi-dance Girls” in Modern Chinese Leisure Sports
Zeng Guang Duan, Ying He, and Jian Gang Qiu
This research examines the introduction and development of ballroom dancing in Modern China, focusing on the cultural clashes, professional evolution, and survival strategies of pioneers like instructors and “Taxi-dance Girls.” It shows ballroom dancing epitomized tensions between Chinese traditions and Western modernity. The transformations of dancing and its pioneers provided insights into China’s socioeconomic transition, urbanization, and modernization. The shift from foreign to Chinese instructors reflected tensions between westernization and localization, as well as China’s cultural awakening. Case studies on instructors enabled nuanced analysis. As commodified entertainers, “Taxi-dance Girls” gained economic sustainability and social mobility through talents and gender charm, though their glamorized images provoked debates on gender relations. By exploring multifaceted roles and experiences of pioneers, this research enriches understanding of entertainment consumption, urban middle-class lifestyles, and Eastern-Western cultural integration in Modern China. It provides new historical materials and perspectives, unveiling complex interplay between cultural globalization and localization.
