Orienteering running, a sport that over time has been associated with bone and joint injuries but which today is known to present no more significant problems than other running sports, fully develops the individual, as it presents stimuli that are not only physical but also other sports, but cognitive and mental. A sportomic and multi-analysis study aimed to investigate the immunometabolic impact generated, comparing its results in two different age groups. Twelve male individuals participated, three adolescents and nine adults, all practitioners of the method. Venous blood was collected before and immediately after testing in a real competition. In relation to the hydration status, mild dehydration was indicated in the adult group and mild hydration in the adolescent group. With regard to renal function, the impact was higher in the adult group, with a statistical difference in this biomarker. Energy metabolism showed a greater demand for triglycerides in the adult group, similar alterations in glycemia, a greater formation of urate in the adult group, a greater decrease in insulin concentrations also in the adult group, with higher values in the group of adults. adolescents only for lactate. A possible greater myolysis was observed, due to the acute increase in LDH in the adult group, with an increase in cortisol for the same group, different from the decrease shown by adolescents. Total leukocytes, phagocytes there was a greater acute impact in the group of adolescents, which was also observed for lymphocytes and eosinophils, but with an antagonistic behavior for the platelets.
