Introduction: Basketball is characterized as an intermittent sport in which currently stand out the highest intensity in which the actions occur, demanding for sport performance the optimum and homogeneous development of physical, technical, tactical, psychological and intellectual components. In this sense, the understanding of the game according to the technical and tactical actions performed and the knowledge of body's responses are important for planning, monitoring and control of the training. Objective: The aim of this study was to describe the intensity of basketball tactical actions and the relationships between technical actions and intensity during the different game periods (GP). Methods: Ten athletes of the Brazilian male basketball elite participated in this study (27.60±5.54 years, 192 (27,60 ± 5,54 anos, 192,62 ± 7,63 cm, 91,60 ± 11,51 kg, 10,66 ± 4,11% de gordura) (27,60 ± 5,54 años, 192,62 ± 7,63 cm, 91,60 ± 11,51 kg, 10,66 ± 4,11% de grasa) RESUMEN Introducción: El baloncesto se caracteriza como un deporte intermitente, en el cual actualmente se destaca la mayor intensidad con que ocurren las acciones, exigiendo para el rendimiento deportivo el desarrollo óptimo y homogéneo de los componentes físico, técnico, táctico, psicológico e intelectual. En este sentido, el entendimiento del juego de acuerdo con las acciones técnicas y tácticas y el conocimiento de las respuestas del organismo son importantes para el planeamiento, monitoreo y control del entrenamiento. Objetivo: El objetivo del presente estudio fue describir la intensidad de las acciones tácticas del baloncesto y las relaciones entre las acciones técnicas y la intensidad a lo largo de los distintos periodos del juego (PJ). Métodos: En este estudio participaron 10 atletas de la elite del baloncesto masculino brasileño en seis partidos de la Liga Nacional de Baloncesto (LNB, Brasil). Se realizaron medidas antropométricas y pruebas motoras y se correlacionaron acciones tácticas (defensiva, ofensiva y de transición), técnicas (número de participaciones [NP] y el índice de eficiencia [IE]) y físicas (porcentaje de la frecuencia cardiaca de umbral de lactato TECHNIQUES AND TACTICS IN BASKETBALL ACCORDING TO THE INTENSITY IN OFFICIAL MATCHES TÉCNICAS E TÁTICAS DO BASQUETEBOL SEGUNDO SUA INTENSIDADE EM PARTIDAS OFICIAIS TÉCNICAS Y TÁCTICAS DEL BALONCESTO SEGÚN SU INTENSIDAD EN PARTIDOS OFICIALES

BackgroundIt is crucial to know the demands on basketball referees, in different match periods (MPs) and phases of competition, for planning referee training and subsequent successful refereeing.ObjectiveTo measure and evaluate the distance covered by referees in a match by measuring the number of interruptions, percentage of heart rate (%HR), and blood lactate concentration ([lac]) in different phases of competition and in different MPs.MethodWe studied the qualifying (QP), semifinal (SP), and final (FP) phases of a total of 12 matches (four matches in each phase) of the 2009–2010 Brazilian Basketball League. Distance covered, number of match interruptions, and referees’ %HR and [lac] were analyzed. We compared the results between competition phases and between MPs (1st MP, 2nd MP, 3rd MP, and 4th MP).ResultsRegarding the distances covered, we observed significant differences (P < 0.05) in the 1st, 2nd, and 3rd MPs between the FP and the other two phases (SP and QP) throughout the match, between each phase; in the 4th MP, a significant difference was found when comparing the QP and the other two phases. Comparing the periods within each phase, we found that a greater distance was covered in the 4th MP in relation to the 3rd MP during the FP. No significant differences were found among the remaining variables.ConclusionThe distances covered by referees in a basketball match increase throughout competition phases. This information is essential for planning of training and for the subsequent success of a referee.

Competitions are considered of paramount importance for high-performancesports because they determine the entire orientation of the training process. When analyzing the calendar of the International Basketball Federation, it can be observed that international competitions occur in short periods of time. In this sense, the aim of this study was to verify the effects of the application of combined training in the short-term preparation period on the speed of athletes of the Brazilian women’s basketball team. Thirteen athletes participated in this study, who took part of the preparation for the 2015 Pan American Games. Athletes were submitted to anthropometric measures and biomotor capacity evaluation at cyclic speed -20m run, and acyclic speed - T test at the beginning (M0) and end of a 27 - day preparation period (M1). Considering the period available for training, the total duration percentage was:technical / tactical 73.7%, strength and conditioning: 5.7%, preventive: 10.5% and general and special warm up: 10.1%. After data collection, the Shapiro-Wilk test was used to verify normality and then, the Student’s T test was also applied. The main results indicate that the best time to evaluate cyclic speed (M0 and M1, respectively) was 3.34 ± 0.22s and 3.39 ± 0.21s and acyclic speed (M0 and M1, respectively), 9.30 ± 0.49s and 9.52 ± 0.57s.The results of the current study suggest that short-term intervention was not efficient to improve the cyclic and acyclic speed of female basketball athletes.

O objetivo do estudo foi verificar se há correlação entre medidas antropométricas e capacidades físicas de 59 meninas participantes do Projeto Segundo Tempo da cidade de Americana-SP, com idades entre 10 a 19 anos. A correlação entre os resultados das medidas antropométricas e os resultados de testes físicos, foi verificado através do coeficiente de Spearman. Os resultados indicam que as medidas antropométricas influenciam as capacidades físicas observadas. Também foram verificadas correlações, estatisticamente significantes entre os resultados dos testes das capacidades físicas. Todos os testes com exceção a flexibilidade se correlacionaram entre si.

ObjetivoIdentificar os determinantes dietéticos do estado nutricional de árbitros da Liga Brasileira de Basquetebol.MétodosParticiparam da pesquisa 47 árbitros da Liga Brasileira de Basquetebol, sendo 9 do sexo feminino e 38 do masculino. Os árbitros responderam a um Questionário de Frequência Alimentar e os escores de padrão de consumo foram atribuídos às categorias de frequência do questionário. Sendo assim, foram verificadas possíveis relações entre os escores de consumo e o índice de massa corporal dos participantes por meio de modelos de regressão linear.ResultadosObservou-se relação positiva significativa (p=0,028) entre idade, sexo, consumo de verduras cruas, chocolate e refrigerantes não dietéticos com o maior valor de índice de massa corporal dos árbitros.ConclusãoOs resultados do presente estudo apontam que a dieta dos árbitros de basquetebol está associada ao seu estado nutricional. Assim, recomenda-se orientação dietética e/ ou ações de educação alimentar e nutricional para esse grupo.Palavras-chave: Basquetebol. Estado Nutricional. Hábitos alimentares.

<p>El propósito de este estudio fue analizar la intensidad de las participaciones directas (PD) o indirectas (PI) en las acciones del juego de baloncesto. Participaron de este estudio siete jugadores, en un juego adulto masculino de la Liga Nacional de Baloncesto (Brasil). Para el partido fue utilizada una filmadora, posicionada en el punto más alto de la gradería y siete transmisores de FC, sincronizados con el tiempo de un cronómetro digital y posteriormente, por análisis de video, con las acciones del juego. Fue considerado PD cuando el jugador participó o se movió para participar efectivamente de la acción; y PI cuando el jugador no participó o no se movió. Fue observado decrécimo &gt;5% en el %FC entre la PD y la PI. La PI en las acciones del juego atiende las situaciones tácticas, puede permitir mayor recuperación y contribuir con el desarrollo en elevada intensidad en las acciones del juego. </p>
