Study based a multicomponent school-based intervention during the school-day (i.e., Physically active learning, active breaks, and active recess) on Physical Activity, health, educational, and cognition outcomes in adolescents.
Adolescents in 1st, 2nd and 3rd year of ESO.
Adolescents with informed consent signed by the family/guardian.
Schools with at least 80 students enrolled in 1st, 2nd and 3rd ESO.
Schools belonging to the regions of Cáceres and Cádiz.
Adolescents with any physical disability or health condition that may limit physical activity levels.
Schools participating in any other physical activity or health promotion program.
Parallel
Multicomponent school-based intervention.
BehavioralPhysically active learning: this type of intervention is carried out once a week for 1 hour outside the classroom. The teachers of the corresponding subject (with the support of the research team) are in charge of the physically active classes. Active break: the intervention consists of 2 active pauses per day. The development of each pause is carried out through a specific digital platform in which students follow the instructions of an avatar, who is in charge of guiding the realization of the active break. Each active break takes a total of 4 minutes, in which two sets of 20 seconds of work and 10 seconds of rest of four different exercises are performed. Active break: The intervention consists of a daily active break, every school day of the week. The design and supervision of each active break will be carried out by the support technician and the teaching staff based on the students' tastes.
Physical activity and sedentary time
Physical activity and sedentary time will be measured through accelerometry (Actigraph GT3X+, Inc., Pensacola, FL, USA).
Cardiorespiratory capacity
The 20-metres shuttle run test will be used to assess cardiorespiratory fitness. Participants will run the 20-metre distance to the rhythm of a recording. The initial speed is 8.5 km/h and will be increased by 0.5 km/h per section. The race will end when the participant stops due to fatigue or when he/she fails to cross the marked lines to the rhythm of the acoustic signals on two consecutive occasions. The last stage or half stage completed by the competitor will be scored.
Musculoskeletal capacity of upper body
The hand grip test will be used to assess musculoskeletal capacity of upper body. The test shall be performed twice with each hand alternately. The maximum score of each hand in kilograms shall be recorded and the mean value between them shall be calculated.
Musculoskeletal capacity of lower body
Standing broad jump shall be used to assess the musculoskeletal capacity of the lower limbs. The participant shall stand behind a line with feet shoulder width apart. The participant is then asked to jump forward as far as possible with both feet. If he/she rests his/her hands or lifts his/her feet off the ground when landing, the test is invalid. The test shall be performed twice, and the best score recorded in centimetres.
Body mass index
Weight and height will be combined to report BMI in kg/m\^2.
