Effect of Body Composition on Aerobic Capacity Level and Post-Workout Restitution during the Training Camp Preparing for the European Wrestling Cadet Men’s Championships

Background: The cognitive objective of the study was to determine the relationship between body composition and aerobic capacity levels at the beginning and end of the training camp and to demonstrate the relationship between body fat levels, free-fat mass levels, and total body water levels and the change in post-workout restitution during the training camp period in preparation for an international wrestling championship competition. Methods: Athletes of the Polish National Team in classical-style wrestling (n = 16) during a training camp before the European Cadet Men’s Championships. Aerobic capacity was analyzed using the Maximal Multistage 20 m Shuttle Run Test (Beep-Test). Post-workout restitution was calculated using the Klonowicz coefficient of restitution. Body composition was analyzed using the electrical bioimpedance method. Results: Significant associations were found between body composition and aerobic capacity and between body composition and post-workout restitution changes during the grouping period. Conclusions: It is necessary to regularly monitor the process of puberty, body composition, and co-occurring adaptive relationships during the period of direct preparation for championship competitions in wrestlers in the cadet age group.
