Brazil is a country member of the Para Report Card, and Brazilian researchers have frequently published information on physical activity of children and adolescents. The current study aimed to analyze the policies for the promotion of adapted physical activity to Brazilian children and adolescents with disabilities. Official government information on adapted physical activity was analyzed from the official websites. Policies were analyzed based on the Para Report Card benchmarks, and after that we used the principles of SWOT (strengths, weaknesses, opportunities, and threats) to analyze the information. Adapted physical activity is not the main focus of any of the many policies to promote physical activity for children and adolescents. Based on the Para Report Card initiative, the score for this indicator in Brazil is D. Brazil needs to develop specific policies to promote physical activity adapted to the pediatric population with disabilities.

This study investigated the process that contributes to the decay of short-term motor memory regarding force reproduction. Participants performed tonic flexion of the right index finger with the target force feedback (criterion phase) and reproduced this force level without feedback 3, 10, 30, or 60 s after the end of the criterion phase (recall phase). The constant error for force reproduction was significantly greater than zero, indicating that information about the somatosensation and/or motor command in the criterion phase is positively biased. Constant and absolute errors were not influenced by the retention interval, indicating that neither bias nor error represents the decay of short-term motor memory over time. Variable error, defined as SD of bias (force in the recall phase minus that in the criterion phase), increased as the retention interval increased. This indicates that the decay of short-term motor memory is represented by the increase in inconsistency of memory bias among the trials. The correlation coefficient of the force between the criterion and recall phases with 3-s retention interval was greater than that with longer intervals. This is explained by the view that the contribution of the information of the practiced force to the force reproduction process is great within 3 s after the end of the practice, but the additional contribution of the noise information becomes greater after this time, causing lesser relative contribution of the information of the practiced force to the force reproduction process.

The goal of the study is to analyze the kinematics and provide an EMG analysis of the support limb during an instep kick in adolescent players. We set a video camera, two torque transducers on the knee, and EMG sensors. A sample of 16 adolescent soccer players between 10 and 12 years old performed kicks. The kinematics shows a p = .039 on frontal plane (dominant 15.4 ± 1.8, nondominant 18.8 ± 1.7); the EMG analysis shows a p = .04 on muscular activation timing for the vastus medialis. A difference between the legs on the frontal plane emerges. Moreover, a huge difference on sagittal plane between the adolescent pattern and adult pattern exists (15° in adolescent population, 40° in adult population). The result shows a greater activation of the vastus medialis in the nondominant leg; probably, in this immature pattern, the adolescents use this muscle more than necessary.

Workaholism (i.e., working excessively and compulsively) is associated with negative physical, psychological, and social consequences. Researchers have previously examined antecedents of workaholism, but the experiences of sport coaches have not yet been investigated. This study explored (a) differences in National Collegiate Athletic Association Division I coaches’ workaholism, as well as need satisfaction and frustration based on gender, coaching role, gender of athletes coached, age, and years of coaching experience; and (b) how coaches’ perceptions of their three basic psychological needs are associated with tendencies to work excessively and compulsively. A total of 873 National Collegiate Athletic Association Division I coaches participated in the research. Data analyses revealed significant differences in participants’ workaholism as well as need satisfaction and frustration. Structural equation modeling indicated a significant relationship between reported levels of workaholism and perceptions of the three needs. Findings illustrate the importance of basic psychological needs in preventing coaches’ workaholism and maintain optimal functioning.

The current study explored coach and athlete reactions and challenges leading up to the Tokyo 2020 Paralympic Games, with a specific focus on the impacts of the COVID-19 pandemic and the Games’ postponement. Nine Australian Paralympic coaches (n = 3) and athletes (n = 6) shared their experiences in semistructured interviews. The thematic analysis highlighted how participants experienced the emergence of the pandemic in different ways, but all were relieved when the late but eventual decision to postpone the Games was made. Regarding lockdown periods (i.e., social-distancing restrictions), some coaches and athletes thrived under the new reality (i.e., training from home, online coaching) while others had more difficulty adjusting. Furthermore, results highlight the many uncertainties still remaining, which continue to influence participants’ sport and personal lives. The experiences of coaches and athletes during the COVID-19 pandemic sheds light on strategies and resources that could support Paralympic coaches and athletes during current and future crises.

Limited research into professional rugby union players’ experiences of seeking formal support for their mental health exists, despite comparable rates of mental health issues among elite rugby players with the general population. This qualitative study explored professional players’ actual experiences of accessing Rugby Players Ireland’s mental well-being service, via separate focus group discussions with professional players (n = 5) and player development managers (n = 4) who refer players into the service. An inductive reflexive thematic analysis identified three themes detailing players’ (a) journey to disclosure of their mental health difficulties, (b) their expectations and engagement with the well-being service, and (c) participants’ reflections on mental health experiences in a high-performance environment. Embedding mental health as a key component of player development in high-performance environments, improving mental health literacy, normalizing mental health experiences, and encouraging help-seeking would help promote player well-being and support holistic development alongside sporting performance.
