Study based on the inclusion of physical activity in the secondary education classroom through active breaks and physically active learning, aimed at testing its effects on the improvement of physical activity levels, sedentary time, educational indicators, cognition and physical and psychological health markers.
The ACTIVE CLASS is a randomized controlled study coordinated by fully qualified researchers in the physical activity and sport sciences from two universities [University of Cadiz (UCA) and University of Extremadura (UEX), Spain]. This study is aimed at 7th and 8th grade students (11-13 years old), belonging to 6 schools in Spain (3 schools in Cadiz and 3 schools in Caceres). One school from each study region will be randomly assigned to one of the three intervention groups:
(i) Active breaks intervention: there will be 2 active breaks per day, 5 days a week of moderate-vigorous physical activity with a duration of 5 minutes.
(ii) Physically active learning intervention: Once a week, moderate-vigorous physical activity will be included in the academic lessons of the mathematics subject.
(iii) Control group.
The interventions will have a duration of 16 weeks. The different outcome measures (physical activity and sedentary behavior, health-related physical fitness, psychological health, academic indicators, cognition, motivational variables, dietary patterns, sociodemographic characteristics and qualitative information) will be evaluated at 3 time points:
All measures will be assessed at each time point with the exception of qualitative information which will be assessed only in the post-intervention measure.
At the end of the intervention the researchers will determine the changes of the main outcome variables. Likewise, the main hypotheses raised will be:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Active breaks | Experimental | Active breaks consist of short breaks during academic classes other than physical education that include moderate to vigorous physical activity, usually unrelated to curricular content. In this type of intervention, 2 active breaks are taken daily in a predetermined time slot. The development of each break is done through access to a specific digital platform where students follow the instructions of an avatar, which is in charge of guiding the realization of the active break. Each active rest involves a total of 4 minutes of activity, in which two sets of 20 seconds of work and 10 seconds of rest of four different exercises are performed, ending with a brief return to calm consisting of two deep breaths. The activities selected for each of the active breaks include aerobic and strengthening activities of moderate and vigorous intensity. |
|
| Physically active learning | Experimental | Physically active learning consists of the incorporation of physical activity (usually of moderate-vigorous intensity) into the educational content taught in academic lessons that do not refer to physical education. This type of intervention is carried out once a week for 1 hour outside the classroom, where physical activity (through movement, jumping, strengthening exercises, throwing, etc.) is incorporated into academic mathematics classes. The mathematics teachers (with the support of the research team) are in charge of teaching the physically active classes. Prior to the development of each class, the research team, together with the mathematics teachers involved, meet and design the class according to the contents to be addressed. |
|
| Control Group | No Intervention | The control group will receive the usual academic classes without any methodological modification during the intervention period. |

| Cardiorespiratory capacity | The 20-metre 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. |

| 6 months |
| 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. | 6 months |
| 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. | 6 months |
| Body mass index | Weight and height will be combined to report BMI in kg/m^2. In both cases the measurement shall be performed twice and the mean shall be recorded. | 6 months |
| Body composition | Waist circumference shall be measured as a body composition variable with a non-elastic tape placed in the frontal plane at the midpoint between the upper iliac spine and the costal border at the mid-axillary line. The measurement shall be taken twice and the mean of the two measurements shall be recorded. | 6 months |
| Subjective physical fitness | The International Fitness Scale will be used for the assessment of subjective physical fitness. Participants will be asked to rate each of the fitness components on a 5-point Likert-type scale ranging from: "very poor" (1); "poor" (2); "fair" (3); "good" (4) and "very good". | 6 months |
| Health status | The EuroQol five dimensions three levels will be used to assessment of health status (EQ-5D-3L).This questionnaire is composed of the dimensions of: (i) mobility; (ii) self-care; (iii) usual activities; (iv) pain/discomfort and (v) anxiety/depression. The three levels that participants should mark a Likert-type scale correspond to (i) no problem; (ii) some problems; (iii) many problem. | 6 months |
| Self-perceived health | Self-perceived health will be measured through the classic self-reported health item, where participants will have to classify their health among the following options: "excellent" (5); "very good" (4); "good" (3); "fair" (2) and "poor" (1). | 6 months |
| School engagement | The engagement scale (UWES-S-9) will be used to evaluate school engagement. The UWES-S-9 is composed of nine items that reflect the three dimensions of engagement: (i) vigor; (ii) absorption; and (iii) dedication, each dimension is represented by three items that will be evaluated through a Likert-type scale, ranging from "never" (0 points) to "always" (6 points). | 6 months |
| Learning perception | Learning perception in mathematics and in general studies will be assessed by means of a questionnaire consisting of eight items. Items 1- 4 will assess the "perceived learning" dimension and items 5-8 will measure the "satisfaction with learning" dimension. All items will be scored according to a five-point Likert scale, where "1" is (strongly disagree) and "5" is (strongly agree). | 6 months |
| Academic performance | Academic performance will be evaluated through the marks reported by the schools before and after the intervention. | 6 months |
| Time on task | Time on task will be assessed by direct observation in mathematics classes or in the classes were the active breaks take place, and in the consecutive class one hour later. Each researcher will assess a total of six students per assessment, where they have 15 seconds per subject to observe, identify the type of behaviour and record it on a worksheet. The researcher will repeat this process for the entire hour. Behaviours will be classified as 'on-task' and 'off-task'. The latter shall be divided into (i) "off-task-motor"; (ii) "off-task-noise"; (iii) "off-task-passive". The percentage of time students spend on each of the behaviours will be recorded. | 6 months |
| Inhibition | Inhibition will be evaluated through the Flanker task protocol, part of the NIH Examiner programme. This is a computerised programme where the subject answers the tests individually. The algorithm provided by the program, ranging from 0 to 10, which includes accuracy and reaction time, will be recorded. | 6 months |
| Cognitive flexibility | Cognitive flexibility will be evaluated through the Shifting task protocol, part of the NIH Examiner programme. This is a computerised programme where the subject answers the tests individually. The algorithm provided by the program, ranging from 0 to 10, which includes accuracy and reaction time, will be recorded. | 6 months |
| Working memory | Working memory will be evaluated through the N-Back protocol, part of the NIH Examiner programme. This is a computerised programme where the subject answers the tests individually. The algorithm provided by the program, ranging from 0 to 10, which includes accuracy and reaction time, will be recorded. | 6 months |
| Novelty | Novelty will be assessed through the Novelty Need Satisfaction Scale. Five of the 19 questions that make up the original scale will be selected and participants will be asked to answer them on a Likert-type scale where 1 = "strongly disagree" and 5 = "strongly agree". | 6 months |
| Enjoyment and boredom | Enjoyment and boredom will be assessed using the Spanish version of The Sport Satisfaction Instrument. This scale is composed of eight items. Participants will have to rate their degree of agreement with the items referring to fun or boredom on a five-point Likert-type scale, ranging from 1 (strongly disagree) to 5 (strongly agree). | 6 months |
| Dietary patterns | Adherence to the Mediterranean diet will be measured using the updated version 2.0 of the KIDMED questionnaire. | 6 months |
| Sociodemographic characteristics | Sociodemographic characteristics will be measured through the Spanish-adapted version III of The Family Affluence Scale. | 6 months |
| Teachers' and students' perception about the suitability and the development of physically active classes and active breaks | perception about the suitability and the development of physically active classes and active breaks (perceptions, barriers, points to improve, strengths...) a semi-structured interview will be conducted with the teachers involved in the intervention. Additionally, and for the same purpose, a discussion group will be developed for each of the proposed interventions with a subsample of students. | 6 months |
