Abstract

World Championship in swimming are the most prestigious competition, where many countries around the world takes part in it. To prepare for the highest level for this type of event, swimmers need to train in adequate training base. Currently, the best center in Poland is at the Floating Arena swimming pool in Szczecin. The aim of this study was to analyze the impact training during start preparation period, on body mass composites. For this study it was examined 14 swimmers, members of the Polish Junior National Team, who were during a training camp in Szczecin, for one month before main competition. Research consisted of 9 measurements of body composites, made by analyzer TANITA BC-420 MA. Method used was bioelectrical impedance analysis (BIA). Components taken under measurements are: body mass (BM), mean body fat (MBF), fat free mass (FFM), muscle mass (MM), total body water (TBW), and body mass index (BMI). All results of the last day of measurements, showed decreasing tendency comparing to the first day of measurements. The statistically important changes were reported in BM, TBW and BMI components. In this 4 weeks start preparation period, all the results slightly decreased. This tendency is highly recommended in professional sports. Research has shown that properly conducted training in the 4-week preparation starter, despite a decline in training loads characteristic of this period, along with a balanced diet, allows to maintain a stable body weight and the distribution of its components directly from participating in the competition, which is of great importance for athletic performance swimmers.
