Our research has been based on the assumption that the cardiovascular and motor development of children, who are constantly developing, requires constant "programme adjustment". However, few studies are available on the periodization of maturity or accumulated training load as probabilistic variables that interact with elements of overall development during the season. Performance tracking thus provides an opportunity to prepare appropriately for the physical demands of each match.

Human biology is an interdisciplinary area of academic study that examines humans through the influences and interplay of many diverse fields such as genetics, evolution, physiology, anatomy, epidemiology, anthropology, ecology, nutrition, population genetics, and sociocultural influences

Motocross is a motorcycle off-road race where performance is usually summarised as the interaction between the rider, the motorcycle and the environment. In this sport, too, there are significant physiological, mechanical and psychological impacts on riders. In motocross, the external and internal forces that the athlete is subjected to require a high level of concentration, short reaction times, fast reflexes and task recognition, as well as considerable physical and mental stamina to compete effectively, so the individual performance of the athlete is particularly decisive, given the state-of-the-art motorcycling technique.
