The purpose of this study was to determine the effect of landmarks on learning basketball lay-up in beginners. Twenty-seven females (age = 20.30 ± 0.24 years, height = 164.37 ± 0.53 cm) participated in this study. They were assigned to three groups: no landmark group, colored landmark group, and black and white landmark group. All participants performed basketball lay-up for six sessions. The colored group and black and white group trained with the landmarks on the ground while the no landmark group trained without any landmarks based on a trainer instruction. Posttest was performed at the end of the last session of training and also in the retention test following 72 hr. All trials were assessed through 5-point Likert scales, ranging from 1 (very poor) to 5 (very good). The results showed that using landmarks significantly changed the lay-up pattern; however, these changes were not significant for color and lay-up shot accuracy.

This paper provides reflections on the progress to date and current status of research in kinesiology. The accompanying overview articles in this special issue of Kinesiology Review show that the contemporary disciplinary/professional foci of kinesiology remain, by and large, the same as the initial research and teaching structures of 50 years ago, as outlined in the inaugural overviews. Nevertheless, within this prevailing disciplinary/professional structure, there have been many new developments in movement-related research, including the juxtaposition of novel alignments and integrations of certain specializations of kinesiology. There is general consensus that the quality and quantity of research in kinesiology have advanced substantially, albeit unevenly, on multiple fronts, both within and between the areas of specialization. The research agenda in kinesiology has benefitted from the growing realization of the centrality of human movement and physical activity in contributing to a healthy lifestyle for individuals and societies.

In 1981, George Brooks provided a review of the academic discipline of physical education and its emerging subdisciplines. Forty years later, the authors review how the field has changed from the perspective of one subdiscipline, motor development. Brooks’s text sets the scene with four chapters on motor development from leaders in the field, including G. Lawrence Rarick, to whom the book is dedicated. From this beginning, the paper describes the evolving scientific perspectives that have emerged since 1981. Clearly, from its past to the present, motor development as a scientific field has itself developed into a robust and important scientific area of study. The paper ends with a discussion of the grand challenges for kinesiology and motor development in the next 40 years.

Background: Many of the known solutions to the physical inactivity pandemic operate across sectors relevant to the United Nations Sustainable Development Goals (SDGs). Methods: The authors examined the contribution of physical activity promotion strategies toward achieving the SDGs through a conceptual linkage exercise, a scoping review, and an agent-based model. Results: Possible benefits of physical activity promotion were identified for 15 of the 17 SDGs, with more robust evidence supporting benefits for 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). Current evidence supports prioritizing at-scale physical activity-promoting transport and urban design strategies and community-based programs. Expected physical activity gains are greater for low-and middle-income countries. In high-income countries with high car dependency, physical activity promotion strategies may help reduce air pollution and traffic-related deaths, but shifts toward more active forms of travel and recreation, and climate change mitigation, may require complementary policies that disincentivize driving. Conclusions: The authors call for a synergistic approach to physical activity promotion and SDG achievement, involving multiple sectors beyond health around their goals and values, using physical activity promotion as a lever for a healthier planet.

Background: Children with developmental coordination disorder (DCD) frequently have difficulties performing gross motor skills such as the overarm throw. Our study examines the differences in both qualitative and quantitative characteristics of overarm throwing for accuracy between typically developing (TD) and children with DCD. Methods: A total of 74 children (36 females/38 males) aged between 7 and 11 years, participated in this study. The authors used the Movement Assessment Battery for Children—second edition to assess motor impairment. In total, 37 (50%) met the criteria for DCD. Each participant completed 10 overarm throws for accuracy at a target. The authors assessed movement quality using the component approach () and quantity using target accuracy. Results: The analyses revealed significantly lower throwing accuracy in DCD versus TD children. Children with DCD also demonstrated fewer component combinations and lower developmental levels than their TD peers. Finally, product scores tracked with process scores. Discussion: Both qualitative and quantitative measures clearly showed that children with DCD are at a disadvantage in controlling a ball during overarm throwing. They used stability profiles that limited coordination variability. TD participants performed more combinations of higher developmental levels to achieve more accurate throws, suggesting they controlled variability to optimize the accuracy of their throws.

The study of sedentary behaviors requires taxonomies (classification schemes) to standardize data collection, measurements, and outcomes. Three taxonomies of sedentary behaviors have been identified, but none address an important challenge in sedentary behavior research, which is to distinguish between beneficial and detrimental health effects of various sedentary behaviors. Some sedentary behaviors (e.g., reading) are associated with positive health outcomes, whereas other sedentary behaviors (e.g., television viewing) are associated with adverse health outcomes. To address directly this complexity and present a different conception and understanding of discrepant findings related to health outcomes, a new taxonomy is needed. The development of the new taxonomy is guided by analysis of literature and selection of a relevant and informative behavioral sciences theoretical framework (i.e., self-determination theory). Because older adults are an increasing percentage of the population and report a high prevalence of sedentary behaviors, the new taxonomy was designed for older adults with potential application to all age groups. Taylor’s taxonomy of sedentary behaviors is parsimonious with four domains: social interaction (i.e., not solitary, companionship, interacting, and connecting with others); novelty (i.e., refreshingly new, unusual, or different); choice (i.e., volition, preferred option or alternative, the power, freedom, or decision to choose); and cognition (i.e., mentally stimulating and engaging).

Background: To improve compliance and adherence to exercise, the concept of temporal consistency has been proposed. Before- and after-work are periods when most working adults may reasonably incorporate exercise into their schedule. However, it is unknown if there is an association between the time-of-day that exercise is performed and overall physical activity levels. Methods: Activity was assessed over 1 week in a sample of 69 active adults (n = 41 females; mean age = 34.9 [12.3] y). At the end of the study, participants completed an interviewer-assisted questionnaire detailing their motivation to exercise and their exercise time-of-day preferences. Results: Participants were classified as “temporally consistent” (n = 37) or “temporally inconsistent” (n = 32) exercisers based on their accelerometry data. The “temporally consistent” group was further analyzed to compare exercise volume between “morning-exercisers” (n = 16) and “evening-exercisers” (n = 21). “Morning-exercisers” performed a greater volume of exercise than “evening-exercisers” (419  vs 330  min by self-report; 368  vs 325  min actigraph-derived moderate to vigorous physical activity, respectively). Conclusions: Our findings suggest that active individuals use a mixture of temporal patterns to meet PA guidelines. Time-of-day of exercise should be reported in intervention studies so the relationship between exercise time-of-day, exercise behavior, and associated outcomes can be better understood.

Background: Built environment approaches to promoting physical activity can provide economic value to communities. How best to assess this value is uncertain. This study engaged experts to identify a set of key economic indicators useful for evaluation, research, and public health practice. Methods: Using a modified Delphi process, a multidisciplinary group of experts participated in (1) one of 5 discussion groups (n = 21 experts), (2) a 2-day facilitated workshop (n = 19 experts), and/or (3) online surveys (n = 16 experts). Results: Experts identified 73 economic indicators, then used a 5-point scale to rate them on 3 properties: measurement quality, feasibility of use by a community, and influence on community decision making. Twenty-four indicators were highly rated (≥3.9 on all properties). The 10 highest-rated “key” indicators were walkability score, residential vacancy rate, housing affordability, property tax revenue, retail sales per square foot, number of small businesses, vehicle miles traveled per capita, employment, air quality, and life expectancy. Conclusion: This study identified key economic indicators that could characterize the economic value of built environment approaches to promoting physical activity. Additional work could demonstrate the validity, feasibility, and usefulness of these key indicators, in particular to inform decisions about community design.

Background: To support the strategy development for communication of the updated physical activity (PA) guidelines, the UK Chief Medical Officers’ Expert Panel for Communication was created. Methods: To help inform this process, a rapid review was performed to identify and describe how other nations are communicating their PA guidelines and PA generally. Elements of the health-enhancing physical activity policy audit tool created by the World Health Organization were used to investigate all 195 countries. Results: Seventy-seven countries had their own guidelines; 53 used the World Health Organization guidelines, and for 65 countries, no guidelines could be found. For the communication, 27 countries used infographics; 56 had government policies/documents, and 11 used a mass media campaign. Only 6 of these had been evaluated. Although many countries used infographics, there were no associated evaluations. As such, any future communication strategies should incorporate an evaluation. Mass media campaigns had the strongest evidence base, proving to be an effective strategy, particularly when incorporating aspects of social marketing. Conclusion: This review provides an insight into strategies countries worldwide have taken to communicate PA guidelines and PA promotion. These should be carefully considered when deciding how best to communicate and promote PA guidelines.
