Propuesta de acciones metodológicas para la enseñanza del bateo en la escuela deportiva de Xalapa, Veracruz

En México, el creciente sedentarismo de la población escolar constituye un serio motivo de preocupación para las instituciones de la salud pública y deportiva. Incluir el béisbol como parte del deporte extraescolar es uno de los retos de las autoridades de la escuela deportiva matutina "Enrique Conrado Rébsamen" de Xalapa, Veracruz. A partir del diagnóstico preliminar, con la aplicación de entrevistas y encuestas a docentes, deportivos y directivos, se constató la escasa documentación, bibliografías, programas e indicaciones metodológicas relacionadas con la enseñanza de los fundamentos básicos del béisbol, y en específico del bateo. Por lo que se plantea como objetivo proponer acciones para la enseñanza del bateo en la escuela deportiva de Xalapa, Veracruz. Se emplearon métodos teóricos como el analítico-sintético, histórico-lógico, inductivo-deductivo y la modelación. Del nivel empírico se utilizó la observación, la entrevista, la encuesta, la revisión de documentos, la técnica Iadov, la triangulación metodológica y el criterio de expertos; además, se utilizó el método estadístico-matemático y se calculó el coeficiente de concordancia de Kendall (W). El resultado demuestra las fortalezas de las acciones para la integración de conocimientos teóricos, prácticos y metodológicos que permite diseñar una herramienta para el trabajo de los docentes deportivos.

A inclusão do beisebol como parte do esporte extracurricular é um dos desafios para as autoridades da escola de esportes matutina "Enrique Conrado Rébsamen" em Xalapa, Veracruz. A partir do diagnóstico preliminar, com a aplicação de entrevistas e pesquisas com professores, esportistas e diretores, foi confirmada a escassez de documentação, bibliografias, programas e indicações metodológicas relacionadas ao ensino dos fundamentos básicos do beisebol e, especificamente, do rebatimento. Portanto, o objetivo foi propor ações para o ensino do rebater na escola de esportes de Xalapa, Veracruz. Foram utilizados métodos teóricos como o analítico-sintético, histórico-lógico, indutivo-dedutivo e modelagem. No nível empírico, foram usados observação, entrevista, pesquisa, revisão de documentos, técnica de Iadov, triangulação metodológica e julgamento de especialistas; além disso, foi usado o método estatístico-matemático e calculado o coeficiente de concordância de Kendall (W). O resultado demonstra os pontos fortes das ações para a integração de conhecimentos teóricos, práticos e metodológicos que permitem a elaboração de uma ferramenta para o trabalho dos professores de esportes.

In Mexico, the increasing sedentary lifestyle of the school population is a serious concern for public health and sports institutions. Including baseball as part of extracurricular sports is one of the challenges of the authorities of the morning sports school "Enrique Conrado Rébsamen" in Xalapa, Veracruz. From the preliminary diagnosis, with the application of interviews and surveys to teachers, sport trainers and managers, it was verified the scarce documentation, bibliographies, programs and methodological indications related to the teaching of the basic fundamentals of baseball, and specifically batting. Therefore, the objective is to propose actions for the teaching of batting in the sports school of Xalapa, Veracruz. Theoretical methods such as analytical-synthetic, historical-logical, inductive-deductive, and modeling were used. From the empirical level, observation, interview, survey, document review, the Iadov technique, methodological triangulation and expert criteria were used; in addition, the statistical-mathematical method was used and the Kendall coefficient of concordance (W) was calculated. The result demonstrates the strengths of the actions for the integration of theoretical, practical and methodological knowledge that allows designing a tool for the work of sports teachers.

Development pattern of swing speed of batting in youth baseball players / 体力科学

The purpose of this study was to determine the developmental pattern of swing speed in youth baseball players between 6 and 14 years old. A total of 1213 baseball players performed toss batting. Swing speed was measured with a specialized accelerometer. In addition, 618 of the 1213 players were measured for total fat free mass by using Inbody770. In study1, Regression analysis was performed on the relationship between chronological age or height and swing speed, and the extreme values were calculated. Then, an allometric equation based on height was also used to estimate the relative growth of swing speed and total fat free mass and to compare the difference of relative growth patterns between swing speed and total fat free mass in study2. Swing speed was strongly related to both chronological age and height, with cubic regression for the relationship with chronological age and linear for the relationship with height. The regression equation obtained for chronological age was solved and found that developmental rate was maximal at approximately 10.25 years old. Allometric analysis showed that the developmental pattern of swing speed differed from that of fat free mass, with a temporary decline in developmental rate from 153.6 cm to 160.9 cm. Based on the results of this study, further research in youth baseball players would be expected to identify the factors causing sluggish development of swing speed as well as to develop an exercise program for improving batting ability.

ABSTRACT For researchers and teachers, this new context of development of physical activity and sports training requires special attention in order to improve the teaching-learning process of Veracruz schoolchildren. In Mexico, and in particular, in Xalapa, Veracruz, the growing and excessive sedentary lifestyle of the school population is a serious concern for public health and sports institutions that leads to low cognitive development and poor development of motor skills, which affects the quality of life of schoolchildren, sports practice with a very focused reference to the practice of baseball, in the Enrique Conrado Rébsamen Morning Sports School are considered two of the fundamental and most preferred pillars in schoolchildren. Batting is considered one of the most complex and important basic fundamentals during the teaching-learning process. Hence, the objective is to propose exercises aimed at improving the batting action to the fifth-grade students of the Xalapa Veracruz Sports School. From the theoretical level analytical-synthetic and historical-logical methods were used; and from the empirical level there were used the document review, interview, survey and scientific observation. The study becomes a tool for sports practice and improvement of the teaching-learning process, and the improvement of coaches.

The Role Of Morphological Traits On The Batting Performance Of Cricket Batsmen – A Review Study

Background: The batting performance is assessed by considering the batting average and strike rate of a batsman. With the induction of T-20 cricket matches, the strike rate of a batsman has gained much attention from coaches and team management. To increase the strike rate a batsman required to hit powerful shots for boundaries, which assist in making maximum scores at the minimum ball. Therefore, this investigation was planned to determine the effect of body size on the batting performance of cricket batsman. Methods: the literature for this study was selected for cricket coaching manual, cricket books, cricket batting videos, a biography of cricket batsmen, research articles. The academic documents were downloaded and shortlisted from Google Scholar, Research Gate, EBSCO, and ProQuest from 1990 to 2019. Results: The synthesized literature review concludes, stature, longer legs, longer arms, and lean body mass of a batsman show positive effects on the execution of powerful shots in cricket. Furthermore, the maximum strength of muscles assists a batsman to boost up the initial velocity of bat swing to accomplish the ball speed for a successful and powerful shot. Conclusions: Although stature and longer limbs of batsmen are associated with batting performance. On the other hand, the specific training would also enhance the capacity of cricket batsman for powerful shots in cricket. A future study was proposed to investigate the effect of training on the batting performance.
