ANALYSIS OF ACUTE RESPONSES OF LACTACIDEMY IN DIFFERENT STRENGTH TRAINING METHODS IN TRAINED MEN

Introduction: Strength training (ST) is one of the most widely practiced forms of exercise today, for individuals of different ages, of both sexes and with different levels of physical fitness. There are several reasons arising from the TF practice, however, there is a large component dedicated to aesthetics, especially to muscle hypertrophy. Objective: To analyze the acute responses of blood lactate (LAC) in different strength training methods. Methods: We evaluated 12 men with experience in strength training (age 27 ± 1.2 years, body mass 80.15 ± 6.5 kg and practice time of 4.5 ± 1.4 years). The study protocol was given by:1) anamnesis and explanation of the research; 2) 1RM test for the bench press exercise; 3) familiarization with the training protocols; 4) perform of isodynamic method (ISO), 5) perform of negative repetitions method (NGT); 6) perform of decreasing pyramid method (PRD); 7) perform of decreasing interval method (ITD); 8) perform of the rest-pause method (RST); 9) perform of wave method (OND). For the analysis of LAC in the methods, they were observed pre and post exercise which was removed 0.1 ml of blood from the right ear lobe of individuals and measured using a calibrated portable device. Results: it was observed that the acute response was statistically significant after the exercises (p <0.05), however there was no difference between exercises and types of stress induced by the same (Metabolic, Tension and Mixed - p> 0, 12). Conclusion: Acute responses after realization of different training methods for muscle hypertrophy increased significantly LAC. Regarding the types of stress induced by exercise (TEM, TE and MIS), the LAC was no significant difference between them; however, it was observed that the methods that induce metabolic stress had greater changes in LAC.  Article visualizations

THE REDUCED GAMES IN FUTSAL AND ITS INFLUENCE IN TACTICAL AND TECHNICAL ACTIONS IN ATHLETES UNDER-13

Currently in Brazil, futsal is one of the most practiced and growing modalities, due to the passion of the Brazilian by the modality, the increase of blocks in the urban areas and the ease to its practice (because it is a sport that uses a reduced space and few players). Therefore, the objective of this study was to verify how adapted games (reduced games) can influence some tactical and technical factors of the modality (ball possession, passes and finalizations). Ten male subjects aged 12 to 13 years participated in the study, who underwent a training periodization composed of 16 sessions based on reduced games only. Before and after the training, games (Game 1 and Game 2) were carried out, which were filmed and were used for scout analysis. Descriptive statistics were used. It was observed after the period of the training sessions increase in the time of possession of total ball during the match, time of possession of defensive ball, certain passes, certain finalizations, and goals scored in favor. In contrast, there was a reduction in offensive ball possession time, number of wrong passes, total number of finalizations and number of wrong finishes. It is observed that the training with reduced games can be effective for the improvement of several technical and tactical components in collective sports games, especially in futsal. As this research approached the descriptive analysis component, we cannot affirm that there were significant changes from Game 1 to Game 2, however, in a simple analysis, small beneficial modifications were observed.  Article visualizations

Introducción: el entrenamiento de fuerza (TF) es una de las formas más ampliamente practicado ejercicio de hoy, para las personas de diferentes edades, de ambos sexos y con diferentes niveles de aptitud física. Hay varias razones derivadas de la práctica TF, sin embargo, hay un gran componente dedicado a la estética, especialmente a la hipertrofia muscular. Objetivo: Analizar las respuestas agudas de lactato en sangre (LAC) en diferentes métodos de entrenamiento de fuerza. Métodos: Se evaluó a 12 hombres con experiencia en el entrenamiento de fuerza (edad 27 ± 1,2 años, la masa corporal 80.15 ± 6.5 kg y el tiempo de la práctica de 4,5 ± 1,4 años). El protocolo de estudio fue dado por: 1) la terminación de la historia y la explicación de la investigación; 2) test de 1RM para el ejercicio de press de banca; 3) la familiaridad con los protocolos de entrenamiento; 4) realización de método isodinámico (ISO); 5) la realización del método de repeticiones negativo (NGT); 6) la realización de disminuir método de pirámide (PRD); 7) realización de la disminución de método de intervalo (ITD); 8) la realización del método de descanso-pausa (RST); 9) la ejecución de método en forma de onda (OND). Para el análisis de LAC en los métodos de entrenamiento, Se observaron el pre y post-ejercicio que se retiró 0,1 ml de sangre de la oreja derecha de los individuos y se midió utilizando un dispositivo portátil calibrado. Resultados: se observó que la respuesta aguda fue estadísticamente significativa después de los ejercicios (p <0,05), sin embargo, no hubo diferencias entre los ejercicios y tipos de estrés inducido por el mismo (metabólico, tensionale y mixta-  p>0,12). Conclusión: las respuestas agudas después de la realización de los diferentes métodos de entrenamiento para la hipertrofia muscular, aumentaron significativamente LAC. En cuanto a los tipos de estrés inducido por el ejercicio (MET, TE y MIS), LAC no mostró ninguna diferencia significativa entre ellos, sin embargo, se observa que los métodos que inducen estrés metabólico tuvieron mayores cambios en la LAC.  Article visualizations

AS AÇÕES TÁTICAS E TÉCNICAS DO FUTSAL PODEM SER MELHORADAS ATRAVÉS DOS JOGOS REDUZIDOS EM CATEGORIAS DE BASE?

Atualmente no Brasil, o futsal é uma das modalidades mais praticadas e que mais cresce, devido a paixão do brasileiro pela modalidade, o aumento de quadras nas áreas urbanas e a facilidade para sua prática (por se tratar de um esporte que utiliza um espaço reduzido e poucos jogadores). Sendo assim, o objetivo deste estudo foi verificar como os jogos adaptados (jogos reduzidos) podem influenciar em alguns fatores táticos e técnicos da modalidade (posse de bola, passes e finalizações). Participaram do estudo 10 indivíduos do sexo masculino com idade entre 12 e 13 anos, que realizaram uma periodização de treinamento composta de 16 sessões pautadas apenas em jogos reduzidos. Antes e após o treinamento foram realizados jogos (Jogo 1 e Jogo 2) que foram filmados e serviram para análise do scout. Utilizou-se estatística descritiva. Observou-se após o período das sessões de treino aumento no tempo de posse de bola total durante a partida, tempo de posse de bola defensivo, passes certos, finalizações certas, e gols marcados à favor. Em contrapartida houve a redução do tempo de posse de bola ofensiva, número de passes errados, número total de finalizações e número de finalizações erradas. Observa-se que o treinamento com jogos reduzidos pode ser efetivo para melhoria de diversos componentes técnicos e táticos nos jogos esportivos coletivos, em especial, no futsal. Como esta pesquisa abordou o componente de análise descritiva, não podemos afirmar que houveram mudanças significativas do jogo 1 para o jogo 2, contudo, numa análise simples, observou-se pequenas modificações benéficas. Currently in Brazil, futsal is one of the most practiced and growing modalities, due to the passion of the Brazilian by the modality, the increase of blocks in the urban areas and the ease to its practice (because it is a sport that uses a reduced space and few players).
