Does school physical education really contribute to accelerometer-measured daily physical activity and non sedentary behaviour in high school students?

Physical education has been highlighted as an important environment for physical activity promotion, however, to our knowledge there are no previous studies examining the contribution of physical education to daily accelerometer-measured physical activity and non sedentary behaviour. The purpose was to compare the accelerometer-measured physical activity and sedentary behaviour between physical education, non-physical education and weekend days in adolescents. Of the 394 students from a Spanish high school that were invited to participate, 158 students (83 boys and 75 girls) aged 13-16 years were analyzed (wear time ≥ 600 min).

A school-based physical activity promotion intervention in children: rationale and study protocol for the PREVIENE Project.

Background: The lack of physical activity and increasing time spent in sedentary behaviours during childhood place importance on developing low cost, easy-toimplement school-based interventions to increase physical activity among children. The PREVIENE Project will evaluate the effectiveness of five innovative, simple, and feasible interventions (active commuting to/from school, active Physical Education lessons, active school recess, sleep health promotion, and an integrated program incorporating all 4 interventions) to improve physical activity, fitness, anthropometry, sleep health, academic achievement, and health-related quality of life in primary school children.

Methods: A total of 300 children (grade 3; 8-9 years of age) from six schools in Granada (Spain) will be enrolled in one of the 8-week interventions (one intervention per school; 50 children per school) or a control group (no intervention school; 50 children).

The Spanish Adaptation of the Sport Motivation Scale-II in Adolescent Athletes.

The aim of this study was to adapt and validate the Spanish version of the Sport Motivation Scale-II (S-SMS-II) in adolescent athletes. The sample included 766 Spanish adolescents (263 females and 503 males; average age = 13.71 ± 1.

Moderate-to-Vigorous Physical Activity Levels in Physical Education, School Recess, and After-School Time: Influence of Gender, Age, and Weight Status.

Background: Primary and secondary school ages have been considered key moments to address the decrease of moderate-tovigorous physical activity (MVPA). Individual (eg, age, gender, and weight status) and contextual factors (moments of the day) need to be considered for a better explanation of the phenomenon. The quantity and quality of physical activity in Physical Education (PE), school recess (SR), and after school (AS) time need to be taken into account to solve the low levels of MVPA in youth.

Introducción: el aumento de la motivación hacia la Educación Física podría resultar un elemento esencial para propiciar un incremento en la condición física saludable de los escolares. La ausencia de estudios en población española hace necesario el desarrollo de esta línea de investigación.Objetivos: el objetivo del presente estudio fue examinar la asociación entre la motivación hacia la Educación Física y los niveles de condición física saludable en adolescentes de Educación Secundaria Obligatoria.

[CONTRIBUTION OF PHYSICAL EDUCATION TO DAILY RECOMMENDATIONS OF PHYSICAL ACTIVITY IN ADOLESCENTS ACCORDING TO GENDER; A STUDY WITH ACCELEROMETRY].

Introduction: the institutionalization of school as a feasible context for the increment of healthy physical activity (PA), the disparity of results in the international context, and the scarcity of Spanish studies with objective measurements in Physical Education (PE), make further investigations in this research line necessary.

Objectives: the objectives were to determine objective levels of PA during PE classes in adolescents, to verify the contribution of PE to daily PA recommendations, and to identify possible differences of PA levels according to gender.

Methods: a sample composed of 394 schoolchildren (211 male and 183 female), from 13 to 16 years old, participated in this study.
