Efecto edad relativa en el baloncesto brasileño a lo largo del tiempo / Relative age effect on brazilian basketball over time

El objetivo de este estudio fue analizar el efecto edad relativa en el baloncesto brasileño durante un período de 15 años mediante la investigación de posibles variables intervinientes. Se analizaron 10856 registros de deportistas de los campeonatos de selección estatales U15, U17, U22 y la liga profesional de 2004 a 2018. Se analizaron la fecha de nacimiento, la altura, la posición en el juego, la región geográfica y el rendimiento del equipo. El efecto edad relativa está presente desde el nivel U15 hasta el nivel de alto rendimiento. Se observó que el efecto edad relativa difiere según la región y la posición del juego. Para concluir, el efecto de la edad relativa es un fenómeno evidente en el baloncesto brasileño desde la Sub15 hasta la liga profesional. Varía según la región geográfica del equipo y la posición del jugador. Esta tendencia se ha perpetuado a lo largo de los años. (AU)

The aim of this study was to analyses the relative age effect in Brazilian basketball over a 15-year period by investigating possible intervening variables. 10,856 records of athletes from youth selection championships U15, U17, U22 and the professional league from 2004 to 2018 were analysed. The birth date, height, game position, geographic region, and team performance were analysed. We observed that the relative age effect is present from the U15 to the high-performance level. It was observed that relative age effect differs depending on region and game position. To conclude the RAE is an evident phenomenon in Brazilian basketball from the U15 up to the professional league. It varies according to the geographic region of the team and the player position. This trend has perpetuated over the years. (AU)

Endurance training improves heart rate on-kinetics in women with subclinical hypothyroidism: a preliminary study.

PURPOSE: The aim of the study was to evaluate the effect of endurance training on heart rate (HR) on-kinetics in patients with subclinical hypothyroidism (SH). METHODS: Eighteen women were randomly assigned to trained group (TG) or control group (CG). Both groups performed three tests at 50 W in a cycle ergometer for 6 min. HR kinetics was obtained during the tests and the mean response time (MRT), which is equivalent to the time taken to reach 63% of the HR at steady state, was extracted. The TG was then submitted to 12 weeks of endurance training (50 min, 3x/week, intensity between 70 and 85% of the maximum HR predicted for the age). Statistical analysis was performed by the mixed analysis of variance. RESULTS: At baseline, TG and CG were similar for TSH (7.7 ± 3.1 vs. 6.9 ± 3.3 mUI/L, p = 0.602, respectively) and FT4 (12.31 ± 1.51 vs. 12.20 ± 1.89 pmol/L, p = 0.889, respectively). After adjustment for body mass index and age, interactions between moment (baseline or after 12 weeks) and group (trained or control) were only significant for MRT (TG: 39.6 ± 10 to 28.9 ± 8.4 s, CG: 53.6 ± 20.3 to 55 ± 19.7 s, p = 0.001) and physical activity level (CG: 7.3 ± 0.7 to 8 ± 0.9, CG: 6.8 ± 0.8 in both moments, p = 0.005). CONCLUSION: The preliminary results suggest that 12 weeks of endurance training improve HR on-kinetics and physical activity level in SH.

Prevalence of rhinitis and related-symptoms in schoolchildren from different cities in Brazil.

By using the standard written questionnaire (WQ), designed for the International Study of Asthma and Allergies in Childhood (ISAAC) we determined the prevalence of rhinitis and its related-symptoms, in Brazilian children and adolescents, living in different cities of the country. The WQ was answered by the parents of 11,403 children aged 6-7 years from five Brazilian cities: Porto Alegre (South, N = 2,846), São Paulo (Southeast, N = 3,005) Uberlândia (Southeast, N = 2,991), Itabira (Southeast, N = 1,151) and Recife (Northeast, N = 1,410). The WQ was also applied to 20,587 adolescents (13-14 years old) living in: Porto Alegre (South, N = 3,195), Curitiba (South, N = 3,004), São Paulo (Southeast, N = 3,008), Uberlândia (Southeast, N = 2,998), Itabira (Southeast, N = 2,134), Salvador (Northeast, N = 3,162) and Recife (Northeast, N = 3,086). The mean response rates were 75% and 95%, for the 6-7 year-old children and for the adolescents, respectively. The data was transcribed to a database (Epi-Info) and analyzed regarding the answers to questions of rhinitis module. The mean prevalence of rhinitis (affirmative response to question 2) was 26.6% and 34.2% in the groups of 6-7 and 13-14 year-old, respectively. Applying the criteria that evaluate the association between nasal and ocular symptoms (affirmative response to question 3) the mean prevalence of allergic rhinitis were 12.8% for the 6-7 year-old children and 18.0% for the adolescents. In conclusion, the prevalence of rhinitis and its related symptoms among children and adolescents living in different Brazilian cities was as high as the prevalence observed in other areas of the world.

La prevalencia de rinitis y de sus síntomas en niños y adolescentes brasileños, que viven en diferentes ciudades, fue determinada por el cuestionario escrito (CE), desarrollado por el International Study of Asthma and Allergies in Children (ISAAC). El CE fue respondido por los padres de 11.403 niños con edad entre los 6-7 años, en cinco ciudades brasileñas: Porto Alegre (Sur, N = 2.846), São Paulo (Sudeste, N = 3.005), Uberlândia (Sudeste, N = 2991), Itabira (Sudeste, N = 1.151) e Recife (Nordeste, N = 1.410).En la faja de edad de 13-14 años el CE fue respondido por 20.587 adolescentes que vivían en: Porto Alegre (Sur, N = 3.195), Curitiba (Sur, N = 3.004), São Paulo (Sudeste, N = 3.008), Uberlândia (Sudeste, N = 2.998), Itabira (Sudeste, N = 2.134), Salvador (Nordeste, N = 3.162) e Recife (Nordeste, N = 3.086).La tasa media de respuestas fue un 75 por ciento para los niños menores y un 95 por ciento para los adolescentes. Los datos fueron transcriptos a una base de datos (Epi-info) y el análisis estadístico fue sobre el modulo rinitis del CE ISAAC. La prevalencia media de rinitis (sí a la pregunta 2) fue 26,6 por ciento y 34,2 por ciento en los grupos de 6-7 y 13-14 años respectivamente. Utilizándose el criterio que evalúa la asociación entre síntomas nasales y oculares (sí a la cuestión 3), la prevalencia media de rinitis alérgica fue de un 12,8 por ciento para los niños de 6-7 años y de un 18,0 por ciento para los adolescentes. En conclusión, la prevalencia de rinitis y síntomas relacionados en niños y adolescentes que viven en diferentes ciudades brasileñas fue tan elevada como la que se ha observado en otras partes del mundo (AU)
