Practicing exercise is one of the best strategies to promote well-being and quality of
life, however physical activity in schoolchildren and adolescents is developed in an
unpredictable, intermittent way and in short periods. There are relatively few intervention
studies investigating the role of physical activity in schoolchildren endocrine function
of adipose tissue and cognitive function. One hundred and three boys, divided into
two groups: control (n = 51, did not perform additional physical activity) and exercise
(n = 52, performed vigorous physical activity after the regular school classes). The
exercise group, developed a 6 months physical activity protocol delivered by the physical
education teacher during the second semester of the academic course (6 months). Body
composition measurements, adherence to the Mediterranean diet, nutritional intake,
hematological and biochemical parameters, endocrine function of the adipose tissue and
biomarkers of brainmolecular function were assessed at enrolment and after 6months of
intervention. No statistically significant differences between both groups were found for
age, height and bone mass. Weight and BMI was lower in the exercise group compared
to the control group, increasing lean mass and reducing fat mass. 58.68% of children
in the exercise group showed high adherence to the Mediterranean Diet compared to
46.32% of the control group. The exercise group was more concerned about their diet
consumed more fiber, vitamin B1, B2, B6, B12, D, Niacin, Folic acid, Fe, Zn, Se and
Cu. Triglycerides levels and HDL-cholesterol were higher in the exercise group at the
end of the study. Leptin, MCP-1, lipocalin-2, adipsin and PAI-1 levels were lower in the
exercise group at the end of the exercise protocol. In contrast, adiponectin and osteocrin
markedly increased in the exercise group. Moreover, marked increases were recorded
in healthy brain state biomarkers (NGF, BDNF, and irisin) in the exercise group, which
could have a positive impact on academic performance. Taken together, all the findings
reported are consistent with many benefits of the exercise protocol on adipose tissue
and brain molecular function, demonstrating the usefulness of early interventions based
on physical activity in children to reduce risk factors related to sedentary lifestyle.
