Multifaceted Analysis of the Adaptation of Rowers in the Process of Sports Training

This study aims to analyze in detail selected indicators of appetite regulation, metabolism, and iron balance in competitive rowers undergoing intense exercise. The project involves assessing dynamic hormonal and biochemical changes in the athletes' bodies, which will allow a better understanding of the body's adaptive mechanisms to prolonged physical strain. Research group: the research will be conducted in a homogeneous group of professional rowers (N=30), all competitors qualified for the Polish Youth Rowing Team: * aged 19 - 24, because the age group must be homogeneous, * the size of the group is about thirty people, which in the case of a homogeneous group will enable statistical analyzes to be conducted. Rowing performance test: At the beginning and end of the training camp, participants will perform a test on a rowing ergometer (Concept II, USA). Each subject will have to cover a distance of 2000 m in the shortest possible time, which is the distance starting in rowing competitions. The results of both tests will be considered in the selection for the championship team; therefore, athletes will be well motivated to perform both tests with maximum effort. Blood samples will be taken from the cubital vein at three-time points: before each ergometer test (after overnight fasting), directly after the test, and after a 1-hour recovery period.
