A Classroom-based Intervention to Promote Physical Literacy in Children: ALPHYL Study Protocol

Study Overview
=================
Brief Summary
-----------------
The goal of this study, named the Active Learning for PHYsical Literacy (ALPHYL) study, was to describe a multicomponent class-based physically-active learning randomized control trial (RCT) in primary school children. The main purpose was to promote children's physical literacy, academic achievement and cognitive function. The ALPHYL study is mainly based on physical literacy, active school models and Supportive, Active, Autonomous, Fair and Enjoyable principles.

Detailed Description
-----------------
The ALPHYL is an 8-10-week RCT that will be conducted in six primary schools (12 classes) in Valencia and its metropolitan area. Schools will be randomly assigned to the intervention or a waiting-list control group. After a 30 h in-person training course for teachers and weekly meetings in the three months of resource preparation, the ALPHYL intervention will be conducted in physical education (PE) and non-PE lessons by teachers. The intervention consists of at least three physically active learning sessions per day plus model-based PE classes. Its feasibility will be evaluated weekly according to the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. To assess its effectiveness, a pre-test, post-test and retention (8-10 weeks after the intervention) with primary outcomes (i.e. physical activity level, motor competence, perceived motor competence and physical literacy, motivation, perceived social support, academic achievement and cognitive function), secondary outcomes and covariates will be collected.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control group<br>Control group | |
| Experimental: Experimental group<br>Physical active learning intervention | Behavioral: Physical active learning<br>* The intervention will last for 8-10 weeks. The ALPHYL intervention will be conducted in physical education (PE) and non-PE lessons by teachers. In addition to the PE lessons, at least three physically active activities in subjects other than PE will be conducted every day (5 days per week), with a total duration of approximately 30 minutes of light and moderate-to-vigorous physical activity per day. The weekly dose of physically active learning will thus be 100-150 minutes, so that a volume of 800-1200 minutes is foreseen during the 8-10 weeks. The PE classes will also be conducted in a mix of cooperative learning, non-linear pedagogy and health-based PE.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of the actual motor competence | Assessment of the actual motor competence using Canadian Agility Movement Skill Assessment test | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the physical activity level | Assessment of the physical activity by accelerometers | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the perceived physical literacy | Assessment of this variable using Physical Literacy for Children Questionnaire. Minimum and maximum response values are from 1 to 4. Higher scores mean a better outcome. | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the perceived motor competence | Assessment of this variable using Pictorial scale of Perceived Movement Skill Competence. Minimum and maximum response values are from 1 to 4. Higher scores mean a better outcome. | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the self-determined motivation for physical activity | Adapted version for children of the Behavioural Regulation Exercise Questionnaire. Minimum and maximum response values are from 1 to 5. Higher scores mean a better outcome. | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the perceived social support | The Physical Activity Family and Friends Support Scale. Minimum and maximum response values are from 1 to 5. Higher scores mean a better outcome. | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the academic achievement | Final grade scores at school | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the working memory | Digit Span test | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 
| Change of the executive function | Stroop test | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of the active commuting to/from school | Survey adapted from Centers for Disease Control Kids-Walk-to-School programme by investigators of the International Physical Activity and the Environment Network. Participants will indicate the number of days travelling both to and from school by walking, bicycling or skateboarding in an average school week. Total number of active trips per week to and from school will be summed (range = 0-10 trips). Higher scores mean a better outcome. | Measured at baseline, immediately after the intervention and 8-10 weeks after the intervention |
