Abstract Aim: To analyze the prevalence of sports practice patterns from childhood to adolescence, and to verify the association between sports practice and demographic factors (sex, age, and skin color), economic factors (maternal education and economic level) and current affinity for physical activities. Methods: A cross-sectional study was carried out with 1,112 adolescents (14-19 years) from southern Brazil. Sports practice patterns were composed of four combinations of sports practice from childhood to adolescence: (1) Practiced in both childhood and in adolescence; (2) Practiced in childhood but not in adolescence; (3) Did not practice in childhood but practices in adolescence; (4) Practice neither childhood nor in adolescence. Demographic, economic variables and current affinity for physical activities were evaluated by questionnaire. Multinomial logistic regression was used. Results: Of adolescents who practiced sports in childhood, 45.8% maintained the practice during adolescence (higher prevalence in males) and 14.1% gave up (higher prevalence in females). Of adolescents who did not practice sports in childhood, 27.6% started during adolescence (higher prevalence in males) and 12.5% maintained their childhood behavior (higher prevalence in females). Adolescents with low economic status who did not practice sports were more likely of not practicing this in both periods. Those who reported not enjoying physical activities were more likely of giving up sports in adolescence. Conclusion: Economic level and affinity for physical activities during adolescence are associated with sports practice patterns. Skin color, age, and maternal schooling are not associated with sports practice.

BackgroundAutism Spectrum Disorder (ASD) children have lower levels of participation in recreational and sporting activities when compared to their peers. Participation has been defined based on the Family of Participation-Related Constructs (fPRC) which defines participation as including both attendance and involvement, with sense of self, preferences and activity competence related to a child’s participation. Modified sports interventions such as Sports Stars can act on physical literacy and some of the fPRCs components. This study aims to assess the feasibility of the Sports Stars Brazil intervention for children with ASD.MethodsThis study will be conducted with 36 participants with ASD aged 6 to 12 years old following the CONSORT for pilot and feasibility recommendation. Participants will be randomly allocated into two groups. Intervention group will receive eight, weekly Sports Stars sessions. Each session will include of sports-focused gross motor activity training, confidence building, sports-education and teamwork development. Study assessments will occur at baseline, immediately post-intervention and 20-weeks post-randomization. First, we will assess process feasibility measures: recruitment, assessment completion, adherence, adverse events and satisfaction. Second, we will investigate the scientific feasibility of the intervention by estimating the effect size and variance at the level of achievement sports-related activity and physical activity participation goals (Goal Attainment Scaling), activity competence (Ignite Challenge, Test of Gross Motor Development-second edition, Physical Literacy Profile Questionnaire, Pediatric Disability Assessment Inventory–Computer Adaptive Test—PEDI-CAT—mobility, 10×5 Sprint Test and Muscle Power Sprint Test), sense of self (PEDI-CAT—responsibility), and overall participation at home, school and community, (Participation and Environment Measure for children and young people, PEM-CY).DiscussionThe results of this feasibility study will inform which components are critical to planning and preparing a future RCT study, aiming to ensure that the RCT will be feasible, rigorous and justifiable.Trial registrationThe trial was registered with the Brazilian Registry of Clinical Trials database (ID: RBR-9d5kyq4) on June 15, 2022.

The objective of this study was to identify the motives for sport participation in a sample of young judo athletes according to sex, age, and training history. A total of 392 subjects aged 12 to 18 years old participated in the study. Portuguese version of the Participation Motivation Questionnaire was used to identify motives for sports participation. Boys reported giving significantly more importance to sports participation in terms of Competition and Skill Development, whereas girls presented significantly higher ratings for Teamwork and Friendship. Motivational factors related to Achievement/Status and Fun presented significantly higher average ratings in younger judo athletes, whereas average ratings of Competition significantly increased with increasing age. Average ratings related to Fitness, Competition and Skill Development were proportionally and significantly higher according to training experience and training volume. These results will contribute to establishing intervention programs designed to reduce sport dropout rates among young judo athletes.
