Examination of changes in body composition depending on the training process in athletes

Introduction: It is well known that continuous physical activity leads to adaptive changes in all organ systems, and they are most noticeable in the body composition parameters. Therefore, it is important to monitor the body composition parameters of top athletes and examine the impact of the training process itself on them, considering their significant impact on the athlete’s overall result. Aim: Examination of the dynamics of changes in body composition depending on the period of the training process in athletes. Material and methods: The research included 152 top athletes - male soccer players (18 to 40 years old), who at the time of the investigation were actively involved in competitive sports and trained at least 3 times and more than 10 hours a week. All data were analyzed from available medical records over a period of 16 years. Results: The only parameters that record a statistically significant difference (p<0.05) between the beginning and the end of the season are the amount of fat expressed in kilograms and the percentage of body fat. Conclusion: According to the results in the examined group of top athletes, the change in body composition does not depend on the training process. The only notable changes were observed in the amount of fat and body fat percentage.
