Childhood obesity increases significantly, and determines several complications in childhood and adulthood, and the worldwide prevalence of childhood obesity has shown a rapid increase in recent decades.

The severity of obesity-related risk factors is directly linked to body fat topography, and variations in body fat distribution in obese children can be of high value in predicting future health risks, like of cardiovascular disease in adulthood.

There is a potential correlation between obesity and sleep disorders, increasing the predisposition to obstructive sleep apnea syndrome, that is a frequent complication, affecting up to 80% of obese children and adolescents.

In relation to postural control, and that anthropometric indicators interfere with children's postural balance, already verified by balance assessment using computerized dynamic posturography.

Several studies show that physical activity in childhood and adolescence can influence healthy habits in adulthood. Children and youth ages 5 to 17 should accumulate at least 60 minutes of moderate to vigorous-intensity physical activity daily.

It is important to emphasize that the COVID-19 has impacted every aspect of healthcare delivery, and therefore Telerehabilitation has been satisfactorily addressed in reabilitation In the exercise recommendations for children, exercise programs performing aerobic and resistance exercises at a high level of intensity, on a frequent basis (3-5 days a week) for 30-80 minutes, seeking intensity of 50-90% of the maximum heart rate (HRmax), can be used and are shown to be efficient for the treatment of obesity. Therefore the High-intensity interval training (HIIT) describes physical exercise that is characterized by brief, intermittent bursts of vigorous activity, interspersed with periods of rest, cab generate favorable metabolic adaptations on sleep and body weight loss.
