An Active Lifestyle Explains Sex Differences in Physical Performance in Children before Puberty

The aim of this study is to analyze differences according to sex in physical performance in children before puberty, as well as other health-related variables. Study population was 137 boys and 156 girls (9.99±0.79 years). We measured weight and height, physical performance using five field tests previously validated in children, habitual physical activity and diet quality. A multinomial logistic regression coefficient was established to calculate odd ratios (OR’s) and 95% confidence intervals (CI’s), to determine sex differences in performance, weight status, habitual physical activity and diet quality, and a t-test was calculated between active boys and active girls in order to establish differences in performance fitness test taking account habitual physical activity. Boys were more actives (OR 1.90, CI 1.03–3.49) and had better weight status than girls, while there was no difference in diet quality between sexes (OR 1.13, CI 0.67–1.89). In total sample, it was more probable to find greater physical fitness values in boys in all test performed. However, when both groups had a similar physical activity pattern, assessed physical fitness variables reached similar values and girls had better results only in flexibility. Sedentary patterns were more frequent in girls although there were no differences in diet quality between sexes. Girls tended to overweight more than boys did. Both sexes had a similar fitness performance before puberty for the same reported physical activity, except for flexibility, inferior in male subjects independently of their physical activity pattern

Analysis and comparison of competitive balance in the Spanish ACB basketball league : a preliminary study

Regardless its relevance in sports economics, competitive balance has not been studied neither in Spanish nor in European professional basketball. In this preliminary study we measured the competitive balance in the Spanish ACB League from seasons 1983/1984 to 2003/2004 using the well-known winning percentage standard deviation index. Results showed great difference between seasons and a general low competitive balance index. In addition, tournament designing did not seem to affect the competitive balance in ACB

The influence of the parents and equals in the realization of physical sports-activity of the students of primary education

El presente trabajo de investigación se centró en conocer la cantidad de actividad física y la intencionalidad de ser físicamente activos en el futuro que tiene el alumnado de sexto de Educación Primaria. Se realizó un estudio de tipo transversal con una estrategia descriptiva y asociativa. La muestra estaba formada por alumnos de centros educativos de la provincia de Badajoz (n=542), el 50.2% eran chicos y el 49.8% chicas, con edades comprendidas entre 11-13 años. Como instrumentos de medida se utilizaron el cuestionario de actividad física para niños (Physical activity questionnaire for children(PAQ-C)) y la Medida de la Intencionalidad para ser Físicamente Activo (MIFA). Se encontraron diferencias en el nivel de actividad física de los escolares (p<.05) en función de las variables género, nivel de actividad física de los progenitores y nivel de actividad física de los amigos. Con respecto a la intencionalidad de practicar actividad física en el futuro se han encontrado diferencias significativas (p<.01) en función del género, la influencia que reciben de los padres cuando se ven obligados a realizar actividad física, el nivel de actividad física de los progenitores y el nivel de actividad física de los amigos. El alumnado que tiene una intención mayor de practicar actividad física en un futuro son aquellos que se consideran bastante activos.The present research work is focused on knowing the amount of physical activity and the intentionality of being physically active in the future that the students of sixth grade from Primary Education. A study was done of transversal type with a descriptive and associative strategy. The sample consisted of students from educational centers in the province of Badajoz (n=542), 50.2% were boys and 49.8% were girls, with ages between 11-13 years. As a measuring instrument, the physical activity questionnaire for children was used (Physical activity questionnaire for children) and the Measure of Intentionality to be Physically Active (MIFA). Differences were found in the physical activity level of the students (p <.05), in function, the variables gender, level of physical activity of the parents and level of physical activity of the friends. With respect to the intentionality of practicing physical activity in the future, significant differences (p <.01) according to gender, the influence they receive from the parents when they are compelled to perform physical activity, level of physical activity of the parents and level of physical activity of the friends. The students that have a greater intention of practicing physical activity in the future are those that are considered quite active.peerReviewe
