Title: Efeitos do foco de atenção no desempenho de sprint de corrida de 25 metros em crianças Abstract: Introduction: Attentional focus refers to the direction of attention during the execution of a motor task and can be classified as internal focus (attention directed to the performer’s own body movements) or external focus (attention directed to the effects of movement on the environment). Studies have shown that an external focus may enhance motor performance and learning in adults. However, in pediatric populations, especially during puberty, the effects of attentional focus remain inconsistent in the literature. Objective: To investigate the effects of different attentional focus conditions (internal, external, and neutral) on 25-meter sprint performance and rating of perceived exertion (RPE) in children. Methods: The sample consisted of 18 children (11 girls and 7 boys), aged between 11 and 13 years, recruited from a public school in Uberlândia, Minas Gerais, Brazil. Participants performed six 25-meter sprints in a single day, with two trials under each experimental condition (internal, external, and neutral). Sprint time was measured using a photocell timing system (Multisprint), recording accumulated and split times throughout the distance. After each trial, participants reported where they focused their attention during the sprint and rated their perceived exertion using the Borg scale adapted from 1 to 10. Data were analyzed using repeated-measures ANOVA, adopting a significance level of p < 0.05. Results: The analysis of accumulated time revealed a significant effect of attentional focus (F = 37.10; p < 0.001), indicating better performance in the neutral condition compared with the internal and external conditions. Similar results were observed for split times, with significantly lower values in the neutral condition. Regarding perceived exertion, a significant effect was also observed (p = 0.037), with lower RPE values reported in the neutral condition compared with the internal focus condition. Conclusion: The findings indicate that, in children aged 11 to 13 years, the absence of specific attentional focus instructions may favor sprint performance and reduce perceived exertion. These results suggest that explicit attentional focus instructions may not be necessary during the execution of this motor task in this age group, highlighting the importance of considering developmental characteristics in sports training and physical education contexts.

Title: Perfil de lesões esportivas em praticantes de modalidades paralímpicas Abstract: The growth of parasports increases the need to understand injury profiles to guide prevention and rehabilitation efforts. This study aimed to characterize the sports injury profile of para-athletes across six Paralympic disciplines and to identify subgroups based on athlete- and sport-related factors that had or had not sustained a sport-related injury in the past year. The study involved 130 para-athletes aged 18 or older who had been practicing their sport for at least one year and had no cognitive impairment. Data were collected in person using a questionnaire. Observed frequencies and percentages for each questionnaire response were calculated to describe the findings. CART analysis was used to determine whether athlete- and sport-related factors predicted a history of injury. Participants reported 56 para-sport-related injuries over the past year. In the majority of cases 44 (78.6%) the athlete did not stop participating; 29 (51.8%) injuries were recurrent, 46 (82.1%) were due to overuse, and 38 (85.7%) occurred during training. The CART model revealed various interactions between injury history and variables such as age, sport discipline, warm-up routines, competitions, participation in other physical activities, sex, and duration of sports practice.

Perfil de lesões relacionadas à prática de Jiu-jitsu

Title: Perfil de lesões relacionadas à prática de Jiu-jitsu Abstract: Jiu-jitsu is a discipline that has integrated well into Brazilian culture, particularly following the creation of Brazilian Jiu-Jitsu (BJJ), a fighting style widely adopted and practiced throughout the country. As with any sport, injury is an aspect associated with BJJ practice. The aim of this study was to characterize the profile of sports injuries affecting BJJ practitioners in gyms and dojos. Additionally, the group of participants reporting a single injury in the past year was compared with the group reporting more than one injury regarding variables related to sports practice. A cross-sectional observational study was conducted, recruiting 79 BJJ practitioners via convenience sampling. Inclusion criteria were: participants of either gender, aged over 18, who had practiced the sport for at least one year with a frequency of at least once a week, and who had participated in at least one competition in the past year, regardless of category or rank. Exclusion criteria were: practitioners of adaptive BJJ and reports of metabolic diseases affecting the nervous or musculoskeletal systems. Data collection was performed individually at each participant's training location; they answered a questionnaire covering characteristics of their sports practice and their injury history over the past year. Among the 79 recruited BJJ practitioners, 72 (91.1%) reported having sustained at least one injury in the past year. Of these, 37 (51.4%) indicated having had one injury, while 35 (48.6%) reported having had more than one (2–5 injuries). The majority of injuries were non-recurrent (n = 112, 87.5%), resulted from trauma (n = 110, 78.1%), and occurred during training (n = 115, 89.8%). The group that reported more than one injury exhibited a higher weekly training frequency (p = 0.009) and used a greater number of personal protective equipment items (p = 0.003). Regarding the reported injuries, participants indicated that in 70 cases (54.7%), they had not yet fully returned to their pre-injury performance level or a higher one. Thus, this study demonstrated a high prevalence of injuries associated with BJJ practice. The findings may contribute to understanding the injury profile of BJJ practitioners and, consequently, to strategies for preventing such injuries.
