Background: Studies related to the motor performance of children have suggested an interaction between organisms and the environment. Although motor development seems to be similar among people, the behavior is specific to the context that people are part of. Thus, the aim of this study was to compare the fundamental motor skill performance between indigenous (IN) and nonindigenous children. Methods: One hundred and thirteen children (43 IN and 70 nonindigenous children) between 8 and 10 years of age underwent the Test of Gross Motor Development—2. Results: A multivariate analysis showed a significant group main effect on both locomotor (p < .01) and object control (p < .01) performance with large and medium effect sizes (ηp2 values = .57–.40, respectively). The IN showed the highest scores for galloping, hopping, leaping, jumping, sliding, striking a stationary ball, stationary dribbling, catching a ball, kicking, and overhand throwing (p < .01) with small to large effect sizes (ηp2 values = .05–.50). Conclusion: The IN presented the highest levels of performance in fundamental motor skills compared with those of nonindigenous children. Most likely, IN have more opportunities for motor development in the environmental context (i.e., villages) where they live.

This best practice paper reflects on a pilot coach education program designed for women coaching Australian Rules football. Focused on enhancing self-regulation, and underpinned by a growth mindset framework, the “Coach like a Woman” program was delivered to a selected group of female coaches either working in or having been identified with the potential to coach at high-performance levels. This manuscript describes the program content and discusses the key insights identified by the delivery team. Creating a community of practice encouraged the transfer of knowledge and experience between the enrolled coaches, which increased competence and self-confidence. Providing an understanding of behavioral tendencies enhanced positive self-talk and aided self-regulation by the coaches. The delivery of the program and challenges experienced are also discussed. This reflection on the program is provided to assist future developments in coach education.

A specific form of corporate social responsibility—corporate philanthropy—has received little attention in sport scholarship despite the increased formalization of this business function in practice. Specifically, few studies have explored the institutional mechanisms that influence the corporate philanthropy of professional sport teams. Given that teams receive simultaneous institutional pressures from their league and from the community in which they operate, this study examined how the presence of multiple peers from different fields affected teams in terms of determining the appropriate level of philanthropic activity. The hypotheses were tested through a longitudinal analysis of philanthropic data from team foundations in four professional leagues in the United States from 2005 to 2017. The authors found that teams were more likely to be affected by the philanthropic giving levels of league peers than local peers. Overall, this study provides a better understanding of simultaneous institutional pressures shaping the philanthropic activities of professional sport teams.

This study investigated (a) site- and direction-dependent variations of passive triceps surae aponeurosis stiffness and (b) the relationships between aponeurosis stiffness and muscle strength and walking performance in older individuals. Seventy-nine healthy older adults participated in this study. Shear wave velocities of the triceps surae aponeuroses at different sites and in two orthogonal directions were obtained in a prone position at rest using supersonic shear imaging. The maximal voluntary isometric contraction torque of the plantar flexors and normal (preferred) and fast (fastest possible) walking speeds (5-m distance) were also measured. The shear wave velocities of the adjoining aponeuroses were weakly associated with plantar flexion torque (r = .23–.34), normal (r = .26), and fast walking speed (r = .25). The results show clear spatial variations and anisotropy of the triceps surae aponeuroses stiffness in vivo, and the aponeurosis stiffness was associated with physical ability in older adults.

A child’s first contact with media and culture typically comes from books they are exposed to in the home and at school. The narratives presented contribute to the early reinforcement of gender roles and norms and can greatly influence the way that young girls perceive and experience sport. The purpose of this study was to explore the narratives within sport-based books geared toward a young female audience to determine the extent to which they promote the engagement of girls in sport. A pragmatic literature search was conducted to obtain books that met our inclusion criteria. Books (n = 28) were analyzed based on the age of their intended audience (aged 3–5, 6–8, and 9–12 years) using thematic narrative analysis. Although the authors promoted the engagement of girls in sport, underlying gender stereotypes were nevertheless salient. Across the books, themes involved the emphasis of “feminine” sports as a context for diversity and learning, the need to understand development as a process, the importance of relationships, and implications pertaining to perceptions of capability as female athletes. Most importantly, the application of a critical feminist lens enabled us to identify an underlying theme—the reinforcement of gender stereotypes—that permeated the storylines and served to undermine the potential adaptive messaging intended by authors. These findings suggest the need for greater attention toward the complexity of female sport and a cultural shift in thinking toward gender equity rather than simply increasing sport access for female participants.

The purpose of this study was to examine how and how often athletic girls were represented on the cover art of young adult (YA) sport fiction. In this research, 154 YA sport fiction books were analyzed using quantitative content analysis. Using existing sport research and theory focused on women’s representation in sport media, the researchers developed a coding scheme to assess cover art for each of the following categories: (a) presence and racial representation of female character/s on cover; (b) portrayal of female body on cover (whole body, partial body/with head, or partial body/without head); (c) portrayal of female character as active or passive; (d) portrayal of female character in or out of athletic uniform; (e) portrayal of female character in or out of the sport setting; (f) presence of sport equipment; and (g) type of cover. Findings revealed that 81% of the book covers had a female character in which 29% of the covers displayed the whole body, 47% displayed partial body/with head, and 23% displayed partial body/with no head of the female character. Only 0.06% of the book covers had a female character of color. Approximately 31% of the female characters were displayed in active positioning, 58% in athletic attire, and 44% in the sport setting. Of the books reviewed, 55% displayed equipment on the cover. The findings indicate that athletic girls have few images on YA sport fiction cover art that accurately represent their athleticism, and there is a clear absence of diverse representation. It is critical that those responsible for the design and layout of book covers clearly represent active females in action, in uniform, and in the sport context.

Elite sprint performances typically peak during an athlete’s 20s and decline thereafter with age. The mechanisms underpinning this sprint performance decline are often reported to be strength-based in nature with reductions in strength capacities driving increases in ground contact time and decreases in stride lengths and frequency. However, an as-of-yet underexplored aspect of Masters sprint performance is that of age-related degradation in neuromuscular infrastructure, which manifests as a decline in both strength and movement coordination. Here, the authors explore reductions in sprint performance in Masters athletes in a holistic fashion, blending discussion of strength and power changes with neuromuscular alterations along with mechanical and technical age-related alterations. In doing so, the authors provide recommendations to Masters sprinters—and the aging population, in general—as to how best to support sprint ability and general function with age, identifying nutritional interventions that support performance and function and suggesting useful programming strategies and injury-reduction techniques.

Male athletes are underrepresented in eating disorders research. This phenomenological study investigated the experiences of male athletes who self-identified as having an eating disorder, disordered eating, or compulsive exercise behaviors. Eight male collegiate athletes were interviewed, and qualitative analysis identified factors associated with the onset and maintenance of disordered behaviors. Among the novel findings was the salient influence of social media as a driver of body dissatisfaction and disordered behaviors. The participants described a perceived sense of control and feeling of pride associated with the use of behaviors, cultural norms in a male sport environment that sustained these behaviors, and a shared belief that, until they experienced a loss of control over their use of behaviors, they would not likely ask for help or seek treatment. These findings have implications for additional research, as well as individual and systems-level strategies for the prevention, screening, and treatment of eating and exercise disorders in male sport.

Background: The specific benefits of aerobic exercises in smoking cessation are unclear, as they have different characteristics, intensities, and durations. The purpose of this systematic review with meta-analysis was to evaluate the effects of aerobic exercise, with or without co-interventions, compared with a control group of cognitive behavior treatment on smoking cessation. Methods: This review was prospectively registered on PROSPERO, and the searches were performed from 2016 to 2018. Randomized controlled trials evaluating the effects of aerobic exercise, with or without nicotine therapy replacement, compared with usual care were included. The primary outcome was smoking cessation defined as the prevalence of those who quit or continuous abstinence. Meta-analysis was calculated using random effects model in the comprehensive meta-analysis software. Results: The authors identified 18 trials reporting data for a total of 2815 participants. There was moderate-quality evidence that aerobic exercise was better than usual care in promoting smoking cessation at short term (11 trials, risk ratio 0.79; 95% confidence interval, 0.66–0.94). However, there were no differences between aerobic exercises and usual care at medium- or long-term follow-ups. Conclusions: According to review, aerobic exercise may be effective in promoting smoking cessation at short-term, but not at medium- and long-term follow-ups.

Background: The purposes of this study were to examine accelerometer measurement reactivity (AMR) in sedentary behavior (SB), physical activity (PA), and accelerometer wear time in 2 measurement periods and to quantify AMR as a human-related source of bias for the reproducibility of SB and PA estimates. Methods: In total, 136 participants (65% women, mean age = 54.6 y) received 7-day accelerometry at the baseline and after 12 months. Latent growth models were used to identify AMR. Intraclass correlations were calculated to examine the reproducibility using 2-level mixed-effects linear regression analyses. Results: Within each 7-day accelerometry assessment, the participants increased their time spent in SB (b = 2.4 min/d; b = 3.8 min/d) and reduced their time spent in light PA (b = −2.0 min/d; b = −3.2 min/d), but did not change moderate to vigorous PA. The participants reduced their wear time (b = −5.2 min/d) only at the baseline. The intraclass correlations ranged from .42 for accelerometer wear time to .74 for SB. The AMR was not identified as a source of bias in any regression model. Conclusions: AMR may influence SB and PA estimates differentially. Although 7-day accelerometry seems to be a reproducible measure, our findings highlight accelerometer wear time as a crucial confounder in analyzing SB and PA data.
