This study aims to examine whether short bouts of exercise (10 minutes) performed during the school day can improve thinking skills, creativity and emotional wellbeing in primary school children. Specifically, children aged 11-12 years will be randomly assigned to perform either a short aerobic exercise break, a strength-based exercise break, or a seated control activity. The study will evaluate how these 10 minutes activity breaks influence attention, working memory, creativity, and emotional wellbeing state after completing cognitively demanding tasks. The findings will help to identify effective strategies to integrate physical activity into the classroom to enhance learning and overall well-being in school settings.
This study investigates the effects of short classroom-based physical activity breaks on cognitive performance, creativity and emotional wellbeing in primary school children aged 11 to 12 years. Many children spend long periods sitting during the school day, which may negatively affect attention, learning, and overall health. Introducing brief "active breaks" during class time has been proposed as a practical strategy to interrupt sedentary behavior and promote both physical and cognitive benefits. In this study, participants will be randomly assigned to one of three groups: an aerobic exercise group, a strength-based (neuromuscular) exercise group, or a control group that remains seated and watches a low-demand video. All interventions will last approximately 10 minutes and will be delivered in a standardized format including a warm-up, main activity, and cool-down. To better reflect real classroom conditions, participants will perform academic tasks (e.g., reading and mathematics) prior to the intervention to induce cognitive fatigue. At baseline, before and after the intervention, children will complete a series of simple tasks and questionnaires designed to assess key aspects of cognitive function, such as attention, working memory, and inhibitory control, as well as creativity and emotional state. In addition, participants will undergo physical fitness assessments (e.g., strength, cardiorespiratory fitness, and body composition). These measures will be used as potential moderating variables or to explore associations between physical fitness levels and cognitive and emotional responses to the activity breaks. The main objective of the study is to determine whether these short activity breaks can produce immediate improvements in cognitive, creativity and emotional outcomes, and whether different types of exercise (aerobic vs. strength-based) have distinct effects. The results of this study may help schools and educators design effective, evidence-based strategies to integrate physical activity into daily classroom routines, with the goal of improving students' learning, wellbeing, and overall development.

A 10-min active break format was selected to maximize feasibility within school settings. All conditions followed an identical temporal structure consisting of a 1-min warm-up, an 8-min main activity phase, and a 1-min cool-down delivered through standardized instructional videos that guided students in reproducing and observing the correct technique and execution of the exercises.

RECRUITINGSelf-perceived emotional state
Assessed using a paper-based measure following the Russell's circumplex model of affect, which conceptualizes emotions according to two primary dimensions: activation level (0 = low to 10 = high) and well-being or happiness level (0 = low to 10 = high).
Time frame: Example assessment timeline: baseline assessment (9:00 a.m.); pre-intervention assessment (following cognitively demanding tasks; 10:00 a.m.); and post-intervention assessment (immediately after the active break protocol; 10:25 a.m.).
Executive Function
The Eriksen Flanker Task and forward and backward digit span tests will be administered online and in paper format, respectively.
Time frame: Example assessment timeline: baseline assessment (9:00 a.m.); pre-intervention assessment (following cognitively demanding tasks; 10:00 a.m.); and post-intervention assessment (immediately after the active break protocol; 10:25 a.m.).
Creativity
Guilford's divergent thinking test will be administered in paper format.
Time frame: Example assessment timeline: baseline assessment (9:00 a.m.); pre-intervention assessment (following cognitively demanding tasks; 10:00 a.m.); and post-intervention assessment (immediately after the active break protocol; 10:25 a.m.).
Socioeconomic status
Socioeconomic status will be assessed using the Family Affluence Scale III (FAS III), a self-reported questionnaire with higher scores indicating higher family affluence.
Time frame: Measured once (one-week before the intervention)
Sleep Pattern
Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI), a self-reported questionnaire with a global score ranging from 0 to 21, where higher scores indicate poorer sleep quality.
Time frame: Measured once (one-week before the intervention)
Self-reported Physical Fitness
Self-reported physical fitness will be assessed using the International Fitness Scale (IFIS), which evaluates overall fitness, cardiorespiratory fitness, muscular strength, speed-agility, and flexibility using a 5-point Likert scale (1 = very poor to 5 = very good), where higher scores indicate better perceived physical fitness.
Time frame: Measured once (one-week before the intervention)
Diet Pattern
Adherence to the Mediterranean diet will be assessed using the Mediterranean Diet Quality Index for children and adolescents (KIDMED), with scores ranging from -4 to 12, where higher scores indicate better adherence to the Mediterranean diet.
Time frame: Measured once (one-week before the intervention)
Physical Activity Enjoyment
Enjoyment of physical activity will be assessed using the Physical Activity Enjoyment Scale (PACES), consisting of 16 items rated on a 5-point Likert scale (1 to 5), with total scores ranging from 16 to 80, where higher scores indicate greater enjoyment of physical activity.
Time frame: Measured once (one-week before the intervention)
Affective State
Negative affect will be assessed using the Negative Affect subscale of the Positive and Negative Affect Schedule (PANAS), which consists of 10 items rated on a 5-point Likert scale (1 = very slightly or not at all to 5 = extremely), with total scores ranging from 10 to 50, where higher scores indicate greater negative affect.
