PHYSICAL EDUCATION AND SPORTS: BIBLIOMETRIC ANALYSIS OF THE ERIC DATABASE

In respect to the growing interest in physical education and sports, the state of this large number of scientific literature and the bibliometric analysis has not been conducted. The purpose of this study to investigate the literature involved physical education and sports topics regarding the descriptive bibliometric analysis. We gathered the open-access data from ERIC within the permission of this database for non-commercial data usages. After a systematic query whole, ERIC database scrapped between the 2010-2019 year and retrieved a total of 365861 journal articles considered of 25573 articles as physical education and sports-related. There were 7581 articles published at the top 25journals (% 29.64). Subjects analysis according to “Physical education” was the commonly associated topic in this field. The findings of this study observed that the ERIC database covered a huge number of articles regarding PE and sports topics. Dynamics of the research literature suggest the US was the first contributor country to both authors and articles. Hence, we conducted a descriptive analysis of the literature indexed in the ERIC database theme include physical education and sports. This study provided a bibliometric analysis of an enormous number of articles after filtering the biggest education basis database

Actividad física y niveles de condición física de los estudiantes del Departamento de Educación Física y Deportes durante la graduación

This study aimed to compare physical activity and fitness of physical education and sports teacher department students and investigate the relationship between physical parameters and academic success. Twenty-five (12 male and 12 female) students volunteered to participate in this study. Sportive background and higher education examination points, shuttle run test scores, and academic success pieces of information of students were taken from the personal folder with the permission of faculty administration. Body composition measured via bioelectric impedance method, shuttle run test performed. Self-admitted international physical activity questionary (long form) was performed. Sportive background and higher education examination points, physical activity levels, and academic success have founded similar within both sexes. However, aerobic capacity results decreased when compared to the entrance of the college with graduation in both male and female students. Also, there was a correlation between VO2max change percentage and academic success. Requirements of physical education and sports department cannot maintain until graduation. These results indicate that there is not an impact of physical tests to graduation quantities of the physical education teacher. However, the relationship between VO2max change percentage and academic success is important indicator that active playing sports and physical activity may be beneficial. To grow up better and more quantitative physical education teachers, future studies require to investigate current physical test which performed the entrance of physical education and sports teacher education and querying that do physical tests a good method to attain requested goals.Este estudio tuvo como objetivo comparar la actividad física y el estado físico de los estudiantes del departamento de educación física y de deportes, e investigar la relación entre los parámetros físicos y el éxito académico. Veinticinco (13 hombres y 12 mujeres) se ofrecieron como voluntarios para participar en este estudio.  Se analizó la composición corporal medida a través del método de impedancia bioeléctrica, se realizó una prueba de funcionamiento de la lanzadera. Se realizó un cuestionario de actividad física internacional. Los antecedentes deportivos y los puntos de examen de educación superior, los niveles de actividad física y el éxito académico han sido similares en ambos sexos. Sin embargo, los resultados de la capacidad aeróbica disminuyeron en comparación con la entrada a la universidad con la graduación en estudiantes masculinos y femeninos. Además, hubo una correlación entre el porcentaje de cambio de VO2max y el éxito académico.  Estos resultados indican que las pruebas físicas no afectan las cantidades de graduación del maestro de educación física. Sin embargo, la relación entre el porcentaje de cambio de VO2max y el éxito académico es un indicador importante de que los deportes activos y la actividad física pueden ser beneficiosos. Para crecer mejores y más maestros de educación física cuantitativos, los estudios futuros requieren investigar las pruebas físicas actuales que realizaron la entrada de educación física y educación de maestros de deportes y consultas que hacen pruebas físicas un buen método para lograr los objetivos solicitados

Standing Handball Throwing Velocity Estimation with a Single Wrist-Mounted Inertial Sensor

Background. It is well known that overarm throwing is one of the most performed activities in the handball. Shoulder and glenohumeral injuries incidence are high in handball because of both pass, and shooting activity was executed repeatedly in high angular speed. Objectives. This study set out to investigate the usefulness of inexpensive commercial inertial movement sensors for prediction of throwing velocity in handball. Methods. After the IMU sensor (500 Hz) placed to the wrist of the dominant arm, players (n=4; 24.4 +/- 1.4 years, 181.75 +/- 11 cm height, 84.58 +/- 16 kg weight) performed 30 standing overarm throwing from a seven-meter distance with 1-minute rest between trials. Throwing velocity compared between radar speed gun and estimations of accelerometer data. Recorded acceleration data filtered (Butterworth 20 Hz 2nd order) than the acceleration vector magnitude calculated. Each throwing data aligned such as 125 data points of before and after the peak acceleration (250ms). Performance metrics of prediction models (Generalized Linear Model, Gradient Boosted Trees, and Support Vector Machine) calculated with root mean square, absolute error, and correlation coefficient parameters. Results. There were reasonably small absolute errors and root mean square values of the machine learning models. Also, there was a very high correlation between measured and predicted velocities with all three models. Conclusion. This is the first study to examined machine learning models to predict handball throwing velocity using a high-frequency triaxial accelerometer. The finding of the present study revealed that the wrist-attached accelerometer precisely estimates the throwing velocity in handball. Further research is required to quantifying the overarm activities in handball, which included block, defensive contact, passing, or shooting. Therefore, the accelerometer-based collected data may provide detection of movement in game-play automatically so that the upper extremity load of players can be monitored and avoid the possible overuse injury risk
