Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Project which objective is to test the effectiveness of an extracurricular physical activity intervention based on high intensity interval training (MOVI-daFit!) on improving cardiorespiratory fitness (CRF), cardiometabolic risk, executive function, and academic performance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the last decade, this research group has tested the effectiveness of three interventions following this model. The first one (MOVI) was carried out in peripuberal age children (4th and 5th year of primary education, 8-11 years) and showed a moderate effect in reducing the adiposity of schoolchildren with higher BMI, an improvement of the lipid profile, without significantly improving the global cardiometabolic risk because it did not produce a reduction in insulinemia.

The second edition (MOVI-2), carried out at schoolchildren of the same age range, increased the duration and intensity of the sessions, and was focused on the development of muscular strength in order to improve insulinemia levels. The intervention showed proved effectiveness; in addition, the data from this intervention showed a modest improvement in girls' aerobic capacity, but not in boys.

The last edition (MOVI-KIDS) was aimed at children aged 4 to 7 years to test the hypotheses that vigorous physical activity at early ages could produce lifelong cardio-metabolic benefits. Data submitted for publication in this study show that, as in the case of the IDEFICS study in children of similar age, the intervention was not effective in improving fitness.

This new edition (MOVI-daFit!) has been designed as controlled cluster-randomized trial including 10 schools from Cuenca province, Spain. Five schools will be randomized to intervention group (IG), in which the intervention MOVI-daFit! will be conducted for children in fourth and fifth school grades (9-11 years old). The other five schools will be allocated to the control group (CG).

During an academic year the 4th and 5th schoolchildren allocated to IG will be carry out, in out of school hours, four times by week, one hour sessions of a standardized recreative, non competitive, physical activity intervention based on games adapted to high intensity interval training methodology (MOVI-daFit!). In the CG regular physical activity will continue.

At the end of the school year the researchers will determine main outcome variables: changes in VO2max, body fat by bioimpedance, reactive hyperemia index, academic achievement, executive function, and biochemical analytic procedures including lipid profile, insulin, HbA1, C ultrasensitive reactive protein and BDNF.

The hypotheses of this new edition will be that the MOVI-daFit! based on high intensity interval training (HITT) adapted for the 4th and 5th schoolchildren, will:

1. Increase the aerobic capacity (VO2max).
2. Reduce the percentage of body fat in the GI versus the GC by 6%.
3. Improve executive function and academic performance.
4. Improve subclinical markers of atherosclerosis (endothelial function and carotid intima-media thickness).

MOVI intervention

\- MOVI-da Fit! is a high intensity interval training intervention that consists on: a) 4 h/week of a standardized recreative, non-competitive physical activity extracurricular program; and b) informative sessions to parents and teachers about how schoolchildren can became more active. It is aimed to enhance physical fitness, motor skills, physical activity time and active behaviours among 9-to-11 years old children.

Group Type EXPERIMENTAL

MOVI intervention

Intervention Type BEHAVIORAL

MOVI-da Fit! is a multidimensional intervention that consists on: a) 4h/week of a standardized recreative, non-competitive physical activity extracurricular program; and b) informative sessions to parents and teachers about how schoolchildren can became more active. It is aimed to enhance physical fitness, motor skills, physical activity time and active behaviours among 9-to-11 years old children.
