- Haemodynamic effect also has individual (fitness and health specifics) and population-level (public health impact) relevance to exercise. - Confirmed evidence about the pupils: differences exist between recovery HR and recovery BP trends: recovery HR remained at a high level, in contrast, the recovery BP decreased to starting level or below. - Established a pilot, exercise-related screening test, called “Fit-test”. It provides an opportunity to gain new insight into the relationship between later manifestations of illness and juvenile burden response. Fit-test is a low-budget, whole-population screening test, which easily fits into an existing school and school health system. We have found that is also suitable for screening for MHT, preHT, and sustained HT students, and for monitoring the effects of treatment. - We established a database, the first large dataset of haemodynamic changes of normal-weight pupils during a field exercise test. We defined the population-specific dynamics and experienced individual dissimilarities. It provided an opportunity to evaluate the physical and cardiovascular fitness together. Established a possibility for subsequent monitoring of the health status of the affected generation, and risk group. This dataset is useful for physical education teachers, coaches, physicians and exercise physiologists to evaluate actual cardiovascular fitness and haemodynamic responses to exercise in children or adolescents and follow its change.
