Clinical Trial Summary

The aim of the 3-year longitudinal study is to investigate the cardiovascular system's response to training loads in young athletes. For the first time, these parameters will be examined alongside biochemical and metabolic laboratory measures, as well as body composition. The study focuses on the impact of training frequency and intensity, as well as performance, on cardiovascular structure and function. The following research questions are being investigated: What structural and functional cardiovascular changes can be observed in young athletes compared to the norm? What is the relationship between cardiac and vascular parameters depending on the athletic load (training frequency and intensity) as well as athletic performance? Do cardiac/vascular parameters change over the course of the study, and what role do athletic load (training frequency and intensity) as well as athletic performance play? What laboratory chemical changes can be observed in young athletes depending on the athletic load (training frequency and intensity) as well as athletic performance? What connections exist between laboratory chemical parameters and cardiac and vascular parameters in young athletes? Is there a correlation between structural and functional cardiovascular changes and body composition as well as eating behavior?
