This study will evaluate the effectiveness of MOVI-OLE! (Open Learning Environment), a school-based intervention designed to reduce sedentary time and enhance multiple aspects of child development, including cognitive function, physical fitness, body composition, psychological well-being, and student engagement. The intervention combines dynamic classroom furniture with student-centered teaching practices. Additionally, a qualitative component will explore how students, teachers, and families perceive the feasibility and acceptability of implementing MOVI-OLE! in real-world school settings.
This study builds on a series of previous school-based interventions (MOVI, MOVI-KIDS, MOVI-da10!, MOVI-HIIT) developed by the research team to promote physical activity and improve health outcomes in children across different educational stages. The new intervention, MOVI-OLE! (Open Learning Environments), aims to address high levels of sedentary behavior during the school day-a growing public health concern associated with poor cardiometabolic health, reduced attention span, and lower psychological well-being in children. MOVI-OLE! introduces structural and pedagogical changes in the classroom by implementing dynamic learning zones-areas with mobile desks, active seating (e.g., stability balls, stools), standing desks, and wall-mounted writable boards. These physical modifications are supported by teacher training in student-centered pedagogy to promote an active and participatory learning environment. The intervention will be evaluated through a stepped-wedge cluster randomized controlled trial involving 10 public primary schools in Ciudad Real, Spain. All schools will eventually implement the intervention but in a staggered sequence across two academic years. The primary study population includes students aged 10-12 years (5th and 6th grades of primary education). A pilot phase will precede the main trial to test feasibility and refine procedures. A mixed-methods approach will be used to assess the impact of the intervention on behavioral, physical, cognitive, emotional, and academic outcomes, as well as to explore perceptions from students, teachers, and families regarding implementation challenges and facilitators.

In the MOVI-OLE! classrooms, traditional desks and chairs will be replaced by three dynamic learning zones: A) Dynamic seating: an area with traditional wheeled desks combined with dynamic seats such as fitballs, stools, pedal desks, etc.; B) Standing desks: an area with manually adjustable high desks to allow standing work. Students will also have stools with small backrests and footrests for when they need to sit; C) Vertical boards: vertical boards (vinyl, paper, chalkboard paint, etc.) installed on walls for standing work. To facilitate use and adapt to classroom routines, teachers will decide how to distribute students among the different zones, with the requirement that all students spend at least 20 minutes per school day in zone B. In addition to the workstations, teachers will receive training and didactic support materials focused on student-centered methodologies and the use of open learning spaces.

Sedentary time in classroom
measured using accelerometers to record sitting/lying, standing, and walking time during classroom activities. Data are expressed as minutes per child during classroom time; higher values of sedentary time indicate greater inactivity.
Time frame: Two academic years
Sedentary Behavior in Classroom
measured in a randomly selected subsample using the Portable Ergonomic Observation Method. Observers will record and classify postures (sitting, standing, walking) during classroom time using real-time coding and/or video recordings. Minutes per child per posture category; higher sitting time indicates more sedentary behavior.
Time frame: Two academic years
Inhibition/Attention
inhibitory control and attention will be measured using the Flanker Inhibitory Control and Attention Test. Children complete practice trials followed by a block of congruent and incongruent trials. Outcomes include reaction time, accuracy, and raw scores, with higher scores indicating better inhibitory control and attentional performance.
Time frame: Two academic years
Working memory
working memory will be assessed using the List Sorting Working Memory Test. Children are required to recall and sequence items presented visually and orally, with task difficulty increasing progressively. Outcomes include raw scores, with higher scores indicating better working memory performance.
Time frame: Two academic years
Cognitive flexibility
cognitive flexibility will be assessed using the Dimensional Change Card Sort Test. Children classify stimuli based on color or shape, with blocks assessing both pre-switch and post-switch performance. Outcomes include reaction time, accuracy, and raw scores, with higher scores reflecting greater cognitive flexibility.
Time frame: Two academic years
Academic performance
academic grades provided by the school in various subjects, comparing the year prior to the intervention and during the intervention years.
Time frame: Two academic years
Mental health
measured with questionnaire such as Revised Children's Anxiety and Depression Scale. This standardized questionnaire assesses a range of anxiety and depression symptoms in children. Responses are rated on a 4-point Likert scale, and scores are converted to age- and sex-normed T-scores. T-scores ≥65 indicate borderline clinical levels, and scores ≥70 indicate clinically significant symptoms.
Time frame: Two academic years
Health-related quality of life
measured with questionnaire KIDSCREEN. This standardized instrument evaluates physical, psychological, and social dimensions of well-being in children and adolescents. Items are rated on 5-point Likert scales, and scores are transformed into T-scores. Higher T-scores indicate better HRQoL.
Time frame: Two academic years
Engagement in the teaching-learning process in students
student engagement (based on the Achievement Beliefs Scale for Children). This self-report instrument evaluates motivational and cognitive components of academic engagement in children, such as effort, persistence, and beliefs about success. Items are rated on Likert-type scales, with higher scores indicating greater levels of engagement.
Time frame: Two academic years
Engagement in the teaching-learning process in teachers
teacher personal efficacy (Utrecht Work Engagement Scale; UWES). This self-report questionnaire measures work engagement through three dimensions: vigor, dedication, and absorption. Items are rated on a 7-point Likert scale. Higher scores indicate greater work engagement and perceived efficacy.
Time frame: Two academic years
Energy expenditure in classroom in different postures
estimation of oxigen (O2) consumption during lessons in traditional seated, dynamically seated and standing desks will be assessed in a a randomly selected subsample. It wil be estimated the O2/hour consumption using a K5 COSMED (Oxycon Mobile system; CareFusion) wireless portable metabolic analyzer.
Time frame: Two academic years
Weight
weight will be assessed twice using a calibrated digital scale with children barefoot and in lightweight clothing.
Time frame: Two academic years
Height
