ABSTRACT

This article analyzed the existing relationship between the subjective perception of effort (RPE) expressed by players and coaches during mini-basket competition and assess the perception of coaches based on the characteristics of the competition. One hundred and fifty players (67 boys and 83 girls) and 25 coaches (19 men and 6 women) participed in this study. For the record of the RPE, the pictorial scale (Eston and Parfitt, 2007) was used. The records were made individually to the players and coaches (at the end of each game period), and to the coaches (at the end of the game). A cross-sectional, descriptive, ex post-fact study was designed using a survey to collect information on the characteristics of training and competition. The results described that players expressed mean RPE = 4.41 ± 1.6 AU. On the other hand, coaches on the RPE of their players as moderate (M = 4.66 ± 1.82 AU), not observing significant differences in RPE according to the sex of the athletes (U = 5060.00; p = .060), the phase of the championship (X2 = .535; p = .765) and the degree of equilibrium of the period (X2 = 5.532; p = .063). However, significant differences were found in the coach's perception of victory (M±SD = 3.91 ± 1.46) or defeat (M±SD = 4.98 ± 1.59) in the match (U = 5265.00; p < .05; d = 0.34). Therefore, we can conclude that the RPE expressed by the coaches agrees with the RPEaverage of the participants of the competition


El presente trabajo ha analizado la relación existente entre la percepción subjetiva del esfuerzo (RPE) que expresan los jugadores y los entrenadores en una competición de minibasket. Los participantes fueron 150 jugadores (67 niños y 83 niñas) y 25 entrenadores (19 hombres y 6 mujeres). Para el registro de la RPE se utilizó la escala pictórica de Eston y Parfitt (2007). Los registros se realizaron de forma individual a los jugadores y jugadoras al final de cada periodo de juego, y a los entrenadores y entrenadoras al final del partido. Se diseñó un estudio transversal, descriptivo, ex post-facto, para el análisis de la RPE de los jugadores y jugadoras, utilizando una encuesta para la recogida de información sobre las características generales y las características del entrenamiento (Thomas, Nelson, Silverman, 2011). Los datos fueron analizados a través de un análisis descriptivo, inferencial y correlacional. Los resultados describen que los jugadores expresaron una media de RPE= 4.41 ± 1.6. Por su parte, los entrenadores valoraron la RPE de sus jugadores como moderada (M= 4.66 ± 1.82 UA), no observando diferencias significativas en RPE en función del sexo de los y las deportistas (U = 5060.00; p = .060), la fase del campeonato (X2 = .535; p = .765) y el grado de equilibrio del partido (X2 = 5.532; p = .063). Sin embargo, si se encontraron diferencias significativas en la percepción del entrenador en función de la victoria (M= 3.91 ± 1.46) o derrota (M= 4.98 ± 1.59) en el partido (U = 5265.00; p < .05; d = 0.34). Por tanto, podemos concluir que la RPE expresada por los entrenadores coincide con la RPEmedia expresada por los participantes de la competición

ABSTRACT

The "Century XXI" Project is a seven-year intervention sport program performed among the best Spanish youth basketball players, who were assigned to one of the following intervention groups based on the following criteria: age, position, mature level, and origin in the country. The study was performed (1996-2001) with a total of 90 players. The main purposes of this study were: a) to describe anthropometric and performance characteristics of top youth international male basketballers in the Spanish national academy; and b) to analyze differences among positions. Insummary, the main findings of this study were: a) the anthropometry presented significant differences between groups under (U-) 14 and U-17; and b) in the U-17 group centers presented more arm span. In our study, the most significant changes are in U-16 vs U-14 and U-15 in strength body up values, and the best result in endurance capacity took place in June of the fourth year. Within this context, the results of the present study may be useful for strength and conditioning coaches to plan their programs with youth basketball players.

ABSTRACT

El presente trabajo ha analizado la percepción del esfuerzo (RPE) en función de género y el índice de masa corporal (IMC) en jugadores y jugadoras de minibasket durante la fase final de una competición. Los participantes fueron 150 deportistas voluntarios, (67 niños y 83 niñas). Se realizaron un total de 230 registros de RPE entre todos los partidos jugados. Para el registro de la RPE se utilizó la escala pictórica de Eston y Parfitt (2007). La altura (cm) fue calculada utilizando un tallímetro y la masa con una máquina de pesaje, ambos del modelo SECA (Germany); el índice de masa corporal (IMC) se calculó a partir de las mediciones de talla y peso. Se desarrolló un estudio descriptivo e inferencial de la RPE del partido en función del género y el IMC. Se implementó un modelo de regresión logística multinomial, calculándose las odds ratio y sus respectivos intervalos de confianza al 95% para establecer el grado de asociación entre la RPE y las variables que han sido objeto de estudio. Los resultados describieron para los chicos una talla media de 152,67 ± 7,94 cm y un peso de 43.7 ± 5,96 kg y para las chicas 154,76 ± 7,72 cm de altura y 43,7 ± 7,14 kg de peso. Respecto a la percepción del esfuerzo, se observó una media de RPE = 4,41 ± 1,61, situándose la tendencia de los valores medios de cada periodo entre RPE = 4 y RPE = 5, con una desviación típica entre 1,60 y 1,95. No se observaron diferencias significativas en función del género, aunque las chicas presentan una RPE ligeramente superior a la de los chicos (AU)


O presente estudo analisou a percepção do esforço de atletas de minibasquetebol (PE) em função do género e do índice de massa corporal (IMC) dos atletas, durante a fase final de uma competição. Participaram 150 atletas (67 crianças do género masculino e 83 do feminino). Realizou-se registos de PE de todos os participantes, um total de 230. Para o registo da PE recorreu-se à escala pictorial de Eston e Parfitt (2007). A altura (cm) foi calculada utilizando-se um telemetro e o IMC foi calculado a partir das medidas de altura e peso. Foi realizado um estudo descritivo e inferêncial da PE considerando o género e o IMC dos participantes. Foi implementado um modelo de regressão múltipla logística, tendo-se calculado os valores de odds ratio e os intervalos de confiança para 95%, com o objectivo de verificar o grau de associação entre a PE e as variáveis objeto de estudo. Os resultados revelaram que o género masculino apresentou uma altura média de 152,67 ± 7,94 cm e uma massa corporal de 43,7 ± 5,96 kg e as meninas 154,76 ± 7,72 cm de altura e 43,7 ± 7,14 kg de massa corporal. No que respeita à percepção do esforço, a média observada da PE foi de 4,41 ± 1,61, situando-se a tendência dos valores médios entre PE=4 e PE=5, com desvio padrão entre 1,60 e 1 , 95. Não foram observadas diferenças significativas, não dependendo do tipo IMC, embora as meninas apresentam umaPE ligeiramente superior à dos meninos (AU)


The present study has analyzed the perception of the effort (RPE) depending on gender and the (body-mass index) index of corporal mass (BMI) in minibasket players during the final phase of a competition. The participants were 150 voluntary sportsmen, (67 children and 83 girls). There were realized a total of 230 RPE’s records among all the played parties. For the record of the RPE there was in use the pictorial scale of Eston and Parfitt (2007). The height (cm) was calculated using by a tallimeter and the body mass with body mass scale, both of the model IT DRIES? (Germany); the (BMI) was calculated from the measurements of height and weight. One developed a descriptive study and inferences of the RPE of the party depending on the gender and the (BMI). A logistic regression multinomial model was implemented, the odds ratio was calculated and the intervals of confidence to 95 % to establish the degree of association between the RPE and the variables that have been an object of study. The results described that the boys presented an average height of 152,67 ± 7,94 cm and a body mass of 43,7 ± 5,96 kg and for the girls 154,76 ± 7,72 cm of height and 43,7 ± 7,14 kg of body mass. With regard to the perception of the effort, RPE’s average observed was 4,41 ± 1,61, placing the trend of the average values of every period between RPE = 4 and RPE = 5, with a standard deviation between 1,60 and 1,95. Significant differences were not observed depending on the kind, though the girls present a RPE lightly superior to that of the boys

ABSTRACT

It was analyzed in what measurement the characteristics of the task in small side games influence the perception of effort (RPE) and his relation between the time of game and the RPE the type of tasks. Ten minibasketball players performed 50 tasks (10 training sessions, 450 records RPE, 5 with duration of 8, 10 or 12 minutes). Based on the description 7 variables were codified: Aim: (Assault / Defense / Compound), Duration: (8 minutes / more than 8 minutes), Space: (Track completes / 1/2 Track / 1/4 of Track), numerical Equality: (Without rival / numerical Inequality / numerical Equality), Transition: (If / Not), Player of support: (If / Not), Relation between players: (attackers[n] x defenders[n]). No parametric analysis and an analysis of the variable RPE in function of the characteristics of the task with logistic multinomial regression from the RPE were used. RPE's average in all the variables were 6.87 ± 1.76. Four variables contribute the model: Time of the task (X2 = 183.49; df= 8; p < .001), Relation among players (X2 = 63.71; df= 10; p < .001), Transition (X2 = 15.37; df= 2; p < .01) and the Aim (X2 = 9.68; df= 4; p < .05). The % of classification of the model for the group RPE (8-9), 90.1 % and for the group RPE (0-6), 71.6 %. The total percentage of classification predicted was 66.4. The tasks of 8 minutes in the group of RPE (0-6) have more possibilities of having RPE lower than those of any more 10 or 12 minutes. The tasks of attack have more possibilities of having a lower RPE. The characteristics of tasks influence the RPE. More than 8 minutes favor a very high RPE when the presence of attackers and defenders in 1x1 and 2x2 exist


Con el objetivo de analizar en qué medida las características de las tareas en los juegos reducidos influyen en la percepción de esfuerzo (RPE), y su relación entre el tiempo de juego y la RPE de los diferentes tipos de tareas, diez jugadores de minibasket desarrollaron 50 tareas (10 sesiones de entrenamiento, 450 registros de RPE, 5 registros de 8, 10 o 12 minutos). Basado en la descripción de 7 variables codificadas: objetivo (ataque / defensa /transición), duración: (8 minutos / más de 8 minutos), espacio: (campo completo / medio campo, 1/4 de campo), igualdad numérica: (sin rival / igualdad numérica/ superioridad numérica), transición: (si / no), ayuda del jugador: (si /no), relación entre jugadores: (atacantes[n] x defensores[n]). El análisis no paramétrico y el análisis de la variable RPE en función de las características de la tarea, se aplicó con una regresión logística multinomial. La media de RPE en todas las variables fue de 6.87 ± 1.76. Cuatro de ellas, contribuyeron al modelo: El tiempo de la tarea (X2 = 183.49; df = 8; p < .001), relación entre jugadores (X2 = 63.71; df = 10; p < .001), transición (X2 = 15.37; df = 2; p < .01) y el objetivo (X2 = 9.68; df= 4; p < .05). El % de clasificación del modelo para el grupo RPE (8-9) fue del 90.1 % y para el grupo RPE (0-6), 71.6 %. El porcentaje total de clasificación fue un predictor del 66.4. Las tareas de 8 minutos tuvieron más posibilidades de presentar una RPE más baja que las de más de 10 o 12 minutos. Las tareas de ataque tuvieron más posibilidades de presentar una RPE más baja. Las características de las tares influyeron en la RPE. Más de 8 minutos favorecen una RPE más alta con presencia de atacantes y defensores en situaciones de 1x1 y 2x2

ABSTRACT

El objetivo del presente estudio fue describir la Percepción Subjetiva del Esfuerzo (PSE) durante la fase final del campeonato de Gipuzkoa (España), en jugadores de baloncesto mini, además de predecir la PSE en función del volumen de entrenamiento de los jugadores. Se realizó un estudio transversal, descriptivo, en el que participaron 150 jugadores de baloncesto. Como instrumento para la recogida de la PSE se utilizó la escala pictórica de Eston and Parfitt (2007). Los jugadores expresaron al finalizar cada periodo de partido disputado de forma individualizada y en una escala pictórica la RPE. Se obtuvo una RPE por periodo de participación con la que se calculó la RPE media de cada jugador en el partido. Se realizó un análisis descriptivo de la PSE y un análisis de regresión múltiple por pasos utilizando como variables independientes los años de práctica deportiva, los años de práctica de Minibasket, el número de sesiones anuales, el número de sesiones semanales y la duración de las sesiones de entrenamiento. Se obtuvo una RPE media del partido de 4.48 ± 1.65, no encontrándose diferencias significativas en función del género (p >.05). Los resultados indican que los chicos se inician significativamente antes que las chicas al minibasket, aunque las chicas entrenan más sesiones anuales y semanales de entrenamiento (p < .01). El modelo predictivo obtenido indica que las cinco variables obtenidas explican un 32% de la variabilidad observada en la RPE media del partido (R2= .32; F = 30.82; p = .00). El entrenamiento específico en minibasket, el número de sesiones de entrenamiento semanal y la duración de las sesiones son predictores de una RPE menor en los jugadores (AU)


The main aim of this study was to describe the Ratings of Perceived Exertion (RPE) during the final championship of Guipuzkoa (Spain), in under-12 basketball players and its relation to workload. It was a transversal descriptive study. It was realized whit 150 basketball players. Since instrument for the withdrawal of the PSE was in use the pictorial scale of Eston and Parfitt (2007). The players expressed on having finished every period of party disputed of individualized form and in a pictorial scale the RPE. A RPE was obtained by period of participation with which there was calculated the average RPE of every player in the game. There was realized a descriptive analysis of the PSE and an analysis of multiple regression by steps using as independent variables the years of sports practice, the years of Minibasket’s practice (under-12 category), the number of annual sessions, the number of weekly sessions and the duration of the training sessions. There was obtained an average RPE of the game of 4.48 ± 1.65, not being significant differences based on gender (p > .05). The results indicated that the boys begin significantly before that the girls to the Minibasket, though the girls train more annual and weekly training sessions (p <.01). The predictive model reflected that five obtained variables explained 32 % of the variability observed in the average RPE of the games (R2 = .32; F = 30.82; p = .00). The specific training in Minibasket, the number of training and weekly sessions and the duration of the sessions are predictors of a minor RPE in the players (AU)
