Intervention With Alternative Sports for Physical and Mental Improvement in Primary School Children

The objective of this clinical trial is to determine whether a school-based intervention involving alternative sports can improve physical fitness, motor skills, and psychological well-being in elementary school students. The main question to be answered is: Can participating in a physical intervention involving alternative sports help children improve their strength, speed, endurance, motor skills, and enjoyment of physical activity? For 8 weeks, during physical education classes, researchers will compare an intervention with alternative sports (korfball, flag football, kin-ball, and ultimate frisbee) with the usual classes that students receive according to their study program, to see if alternative sports improve physical and psychological aspects. Participants must: * Perform physical and motor tests to determine their initial physical condition * Complete a questionnaire to determine their level of enjoyment during physical activity. * Actively participate in an 8-week intervention during physical education classes. * Monitor their level of physical activity during classes using a device (accelerometer). * Authorize the use of their first semester grades. * At the end of the intervention, physical and motor tests will be performed again to assess progress and physical changes. For eight weeks, researchers will conduct a study in physical education classes to compare two types of teaching: one based on alternative sports (such as korfball, flag football, kin-ball, and ultimate frisbee) and another with traditional school program classes to see if children improve physically and psychologically.
