No Intervention: Control Group
The control group will use conventional school furniture.
Experimental: Adjustable Furniture Group
The experimental group will use adjustable ergonomic school furniture.
Device: Adjustable Furniture
The intervention will include adjustable school furniture.
- Change of weekly physical activity levels [ Time Frame: 5 days ]Weekly physical activity levels will be measured with accelerometers.
- Change of sitting time [ Time Frame: 5 days ]Weekly sitting time will be measured with accelerometers.
- Adolescent Sedentary Activity Questionnaire [ Time Frame: Baseline and after 5 days. ]The Adolescent Sedentary Activity Questionnaire is used to subjectively assess sedentary behavior. Students are asked to think about a normal week, during school term, and to report how long they usually spent engaged in 11 different sedentary behaviors before and after school on each day of the week and on each day of the weekend. If two activities occurred at the same time (e.g., one hour in front of the television doing homework) the students are asked to estimate how much time was spent on each activity during that time (e.g., 45 min television and 15 min homework). Time spent in each category is calculated and time is also summed across categories to yield the total time per week spent in sedentary behavior. Higher outcome values present longer time in sedentary behavior (worse outcome).
- Physical Activity Questionnaire for Adolescents [ Time Frame: Baseline and after 5 days ]Physical Activity Questionnaire for Adolescents is used to subjectively assess physical activity levels. The questionnaire addresses a habitual week. It consists of three sections, including physical activity in school, during transportation and leisure-time. Each section is further divided into different activity categories. School section: physical education and breaks between lessons. Transportation section: walking and cycling at least 10 minutes at a stretch. Leisure-time section: activities at least 10 min long. A measure of physical activity is then reached by multiplying the time spent for each activity with the corresponding metabolic equivalent (MET-value). Higher outcome value is better, since it indicates a higher level of physical activity and MET values.
- Anthropometric measurements of the students performed with anthropometer [ Time Frame: Baseline ]Anthropometric measurements will be performed to obtain the main measures that are needed to evaluate the user-furniture mismatch. All the measures will be taken with standard anthropometer, the unit of measure will be centimeter. We will measure Popliteal height, Buttock-popliteal length, Subscapular height, Thigh thickness. Elbow height sitting, Shoulder height sitting. With the measures obtained we will calculate the furniture mismatch for the following: Seat height, Seat depth, Seat to desk clearance, Desk height, Seat width, Upper edge of backrest. Higher percentage of the mismatch between the student's anthropometric measures and furniture indicates a worse outcome.
- Sitting posture [ Time Frame: Baseline and after 5 days ]The sitting posture will be evaluated with RULA (Rapid Upper Limb Assessment) tool.
