About this trial

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.

Treatments tested in this trial

Intervention with Alternative Sports (kin-ball, korfball, ultimate frisbee and flag football))
Other intervention
The RENUÉVATE intervention will be implemented by previously trained physical education teachers. It will last for two months, with sessions held twice a week. The sessions will take place during the school day, in physical education classes, and will last 90 minutes. Each two-week block will be dedicated to an alternative team sport (flag football, ultimate frisbee, korfball, and kin-ball). The physical load for each session is as follows: Warm-up (15 min): general mobility and specific exercises to prepare for the sport in question, maintaining an intensity of 50-60% HRmax; RPE 9-11. Main part (65 min): practice of the alternative sport through games and technical/tactical progressions. An intensity of 65-80% HRmax will be prescribed; RPE 12-15, with active breaks between tasks. Cool down (10 min): relaxation, stretching, and group reflection activities with a light intensity \<50% HRmax; RPE ≤ 9.
Intervention with regular classes from the school curriculum
Other intervention
The intervention will be implemented by physical education teachers who have been trained in the project's objectives, methodology, and values. The training will include a standardized manual and a two-hour weekly practical session to ensure fidelity in the program's implementation. In addition, weekly monitoring meetings will be held with the research team to resolve questions and ensure consistency across schools.

Trial outcomes

Primary outcomes

Motor competence

It will be assessed using the Motorishe Basiskompetenzen (MOBAK) battery, which evaluates body control (balance, rolling, jumping) and object control (throwing, catching, bouncing, dribbling), used in schoolchildren aged 10 to 12. For throwing and catching tasks, children have 6 attempts (no trial attempts), in which the number of successes, i.e., successful attempts, is recorded. These are then scored: 0 to 2 successes, 0 points; 3 to 4 successes, 1 point; and 5 to 6 successes, 2 points. For the tasks of driving with the hand, driving with the foot, balancing, rolling, jumping, and running. Children have 2 attempts to complete the task (no trial attempts). The scoring of these tests is based on a dichotomous scale (0 = not achieved, 1 = achieved), in which the number of successful attempts is recorded (never achieved = 0 points; achieved once = 1 point; achieved twice = 2 points). The score from 0 to 8 determines the level of basic motor skills in a differentiated manner.

Time frame

It will be evaluated on day 1 (pre-test) and day 16 (post-test).

Cardiorespiratory capacity

Cardiorespiratory capacity will be assessed, using tests that have been widely validated in school populations: For cardiorespiratory capacity, a 6-minute walk test will be used to estimate VO₂max.

Time frame

A measurement will be taken at the start of the intervention on day 1 (pre-test) and another assessment will be carried out at the end of the intervention on day 16 (post-test).

Muscle strength (Lower Limb )

Lower limb muscle strength will be assessed using tests that have been widely validated in school populations: the Bosco Test (squat jump (SJ) and counter-movement jump (CMJ) on a force platform.

Time frame

A measurement will be taken at the start of the intervention on day 1 (pre-test) and another assessment will be carried out at the end of the intervention on day 16 (post-test).

Muscle Strength (Upper Limb)

Grip strength will be assessed using a Camry EH101 hydraulic dynamometer, which is known for its high accuracy.

Time frame

A measurement will be taken at the start of the intervention, on Day 1 (pre-test), and another assessment will be conducted at the end of the intervention, on Day 16 (post-test).

Secondary outcomes

Body Composition (Bioelectrical Impedance Analysis)

Name of the measure: Body fat percentage Description: Body composition will be assessed using eight-electrode tetrapolar bioelectrical impedance analysis with the InBody 570® device. The outcome corresponds to body fat percentage obtained according to the manufacturer's standardized measurement protocol. Unit of measure: Percentage (%) Range: 0 to 100 percent. Direction of outcome: Lower values indicate a better outcome.

Time frame

It will be evaluated on day 1 (pre-test) and day 16 (post-test)

Morphological variables (Body Height)

Name of the measure: Body height Description: Body height measured following ISAK standardized protocols by an ISAK Level II anthropometrist. Unit of measure: Meters (m) Range: No predefined minimum or maximum values. Direction of outcome: Not applicable (descriptive anthropometric measure).

Time frame

It will be evaluated on day 1 (pre-test) and day 16 (post-test).

Morphological variables (Body Weight)

Name of the measure: Body weight Description: Body weight measured according to the International Society for the Advancement of Kinanthropometry (ISAK) standardized protocols by an ISAK Level II anthropometrist. Unit of measure: Kilograms (kg) Range: No predefined minimum or maximum values. Direction of outcome: Not applicable (descriptive anthropometric measure).

Time frame

It will be evaluated on day 1 (pre-test) and day 16 (post-test).

Morphological variables (Body Mass Index)

Name of the measure: Body Mass Index Description: Body Mass Index calculated as body weight in kilograms divided by height in meters squared (kg/m²), using measurements obtained according to ISAK standardized protocols by an ISAK Level II anthropometrist. Unit of measure: Kilograms per square meter (kg/m²) Range: No predefined minimum or maximum values. Direction of outcome: Lower values indicate a more favorable body composition.

Time frame

It will be evaluated on day 1 (pre-test) and day 16 (post-test).

Other outcomes

Sociodemographic Characteristics (Covariates)

Name of the measure: Family socioeconomic status Description: Family socioeconomic status will be assessed using a questionnaire completed by parents or legal guardians. The questionnaire will collect information on parental educational level, household income, and family structure. These variables will be combined to classify participants into predefined socioeconomic status categories for descriptive and adjustment purposes. Unit of measure: Categorical variable (low, medium, high socioeconomic status). Range: Not applicable. Direction of outcome: Not applicable (descriptive covariate)

Time frame

It will be evaluated on day 1 (pre-test) and day 16 (post-test).
