Brief Summary

An adequate physical activity level has important effects on cardiovascular health of children. However, the scientific literature suggests that few children meet the physical activity recommendations to obtain these cardiovascular benefits which may have immediate and long term consequences in public health. High intensity interval training (HIIT) has emerged as an effective strategy for improving physical and mental health in children. To note that HIIT can be completed in a shorter period of time and its results in physical health seem to be equivalent to those obtained in longer sessions of traditional aerobic training. However, there is no information about the dose of HIIT needed to obtain significant effects on cardiovascular health of children. The adoption of healthy dietary habits is also important in the prevention of obesity and cardiovascular diseases. School-based programs including physical activity and nutritional education have been recommended as important components of programs aiming to prevent obesity and cardiovascular diseases.

HIIT one session

EXPERIMENTAL

One session per week of HIIT + nutritional education (1 session/week)

Behavioral: High intensity interval training; Behavioral: Nutritional education

Interventions

High intensity interval training BEHAVIORAL

Two schools with four classes/groups of 4th degree of children will participate in the pilot study (i.e., age of children 9-10 years old). One of them has two physical education (PE) sessions per week and the other has only one PE session per week. In the school with two PE sessions, two classes will be randomly assigned to HIIT (2 sessions/week) +nutrition group, and two to the nutrition group. Similarly, in the school with one PE session per week, two classes will be randomly assigned to HIIT (1 session/week) + nutrition and two classes to the nutrition goup. Both HIIT and nutritional education sessions will be integrated integrated into the physical education and sciences sessions of the schools. The duration of the intervention will be of eight weeks.

HIIT one session; HIIT two sessions

Nutritional education BEHAVIORAL

School-based nutritional education on healthy dietary habits

HIIT one session; HIIT two sessions; Nutritional education
