Percepción de esfuerzo, diversión y aprendizaje en alumnos de educación secundaria en las clases de Educación Física durante una Unidad Didáctica de CrossFit

This research aims to know the enjoyment, learning and intensity level perception in Physical Education lessons during a CrossFit Educational Component and the relationship among gender and educational level. In order to that, a total of 104 secondary students whose ages vary from 12 to 16 years old have filled in two questionnaires about enjoyment, learning and effort perception. The results have shown high levels of enjoyment, effort and learning perception in the students thought CrossFit practice. Thus, boys perceive higher enjoyment and intensity than girls, and it has found that students in upper secondary perceive physical education lessons as more intense and less fun.

Game Performance and Length of Rally in Professional Padel Players

Abstract The purpose of this study was to analyse differences in rally length considering attack effectiveness, a players’ location and a game outcome in professional padel players. A total of 1527 rallies from 10 male matches of the 2013 Masters Finals of the World Padel Tour were registered through systematic observation. Data treatment included non-parametric mean comparisons (Mann-Withney and Kruskal-Wallis tests), and association analyses (crosstabs and Chi square analysis). In overall, 40% of unforced errors were made within the first 4 s of the rally, over 50% of points were scored between the 5th and 11th s, and 30% of forced errors occurred after the 11th –s of the rally. Hence, the ability to score in rallies of over 11 s duration and not making unforced errors within the first 4 s contributed to the rally outcome. More specifically, winners played longer rallies compared to losers (10.42 ± 7.77 s vs. 8.42 ± 6.43 s); particularly at the net, when scoring from the baseline (11.04 ± 7.64 s vs. 8.90 ± 5.41 s) and making forced (8.86 ± 7.44 s vs. 6.86 ± 6.24 s) and unforced errors (11.91 ± 9.47 s vs. 8.33 ± 6.92 s). Such knowledge may have implications in the design and structure of specific training programmes for padel players according to competition requirements.

Motivos de género para la práctica de pádel

espanolEl objetivo de este estudio fue detectar los motivos de practica en jugadores regulares de padel. Se accedio a un total de 77 participantes (43 hombres y 34 mujeres) de la Comunidad Autonoma de Extremadura (Espana). Se utilizo la version validada al espanol de la escala de medida de los motivos para la actividad fisica, revisada (MPAM-R). Se realizaron calculos de comparacion de medias a traves del anova de un factor para estudiar las diferencias dentro de cada genero, y la t-Student para conocer las diferencias entre hombres y mujeres. Los resultados revelan diferencias en los motivos de practica dentro del genero femenino en relacion con el rango de edad, tiempo de practica, dias de practica y nivel de juego. Destacan las elevadas puntuaciones otorgadas a la competencia (F = 8.677; R 2adj = 0.48) y al aspecto social (F = 4.253; R 2adj = 0.28) en mujeres de mas de 40 anos, y al fitness/salud en jugadoras con una practica regular de 6 meses a 3 anos (F = 23.553; R 2adj = 0.73). Se observaron tambien diferencias entre hombres y mujeres, siendo relevantes las controversias en los motivos que mueven a practicantes con menos de 6 meses de experiencia. Dichos resultados ofrecen informacion relevante sobre los motivos de practica del padel, siendo de utilidad para el desarrollo de planes de actuacion que potencien la adherencia al deporte, la mejora de la salud y calidad de vida de las personas, evitando el abandono de la practica de actividad fisica y el sedentarismo, especialmente en adultos de mas de 35 anos EnglishThe purpose of this study was to detect the reasons why regular players practice paddle tennis. A total of 77 participants (43 men and 34 women) from the Autonomous Community of Extremadura (Spain) were surveyed. The validated Spanish version of the revised Motives for Physical Activity Measure (MPAM-R) was used. Calculations were performed to compare means through a one-factor ANOVA to study differences within each gender, and the Student t-test was used to ascertain the differences between men and women. The results reveal differences in the reasons for practicing paddle tennis within females in relation to the age range, practice time, days of practice and level of play. What stand out are the high scores given to competition (F = 8.677; R 2 adj = 0.48) and the social aspect (F = 4.253; R 2 adj = 0.28) in women over the age of 40, and to fitness/health in players who have been practicing between 6 months and three years (F = 23.553; R 2 adj = 0.73). Differences were also found between men and women, and the differences in the reasons why practitioners with less than 6 months of experience play are particularly prominent. These results provide relevant information on the reasons why people practice paddle tennis and can be useful when developing action plans that encourage adherence to the sport, improved health and quality of life, preventing the abandonment of physical activity and sedentarism, particularly in adults over the age of 35.

Satisfacción laboral en los docentes de educación infantil, primaria y secundaria

The objective of this study is to assess how socio-demographic factors impact job satisfaction among teachers. The sample group included 163 teachers (52 males and 121 females) between the ages of 23 – 60 (M=37.40 ± 8.86) in 12 schools located in Murcia, Spain. The study was based on the Teacher Satisfaction Scale (TSS), a survey made up of 32 items grouped together into 5 categories. Although results showed an overall medium-high level of teacher job satisfaction, permanent, part-time Preschool, Physical-Education teachers reported significantly higher scores in their job satisfaction levels.

Prevalencia del síndrome de Burnout en tenistas según su orientación motivacional

El objetivo de este trabajo ha sido determinar el nivel de burnout en un grupo de tenistas de alto rendimiento y conocer la relacion existente entre la orientacion motivacional y los niveles de burnout, asi como la influencia de las variables sociodemograficas. Para ello, se ha tomado como muestra a 84 jovenes jugadores de tenis de elite procedentes de dos academias de alto rendimiento, a los que se les administro el Inventario del Burnout para Deportistas y la Escala de las Orientaciones de Meta en el Ejercicio. Los resultados obtenidos en esta investigacion han mostrado que el 4,8% de la poblacion de estudio presenta burnout en todas sus dimensiones y una relacion estadisticamente significativa entre las horas de entrenamiento y las dimensiones de agotamiento emocional y despersonalizacion. Por ultimo, existe una correlacion negativa estadisticamente significativa entre la variable orientacion hacia la tarea y la reducida realizacion personal para los tenistas estudiados.
