Table 1: Descriptive characteristics of performance, restitution, and body component variables in the first and second terms of the study on the Polish national men’s classical wrestling team, in the cadet age group (n = 16). Between the second and first terms, there was a negative medium significant correlation between distance vs. weight [kg] (r = \(-\)0.65; \(p<\) 0.01), FFM [kg] (r = \(-\)0.67; \(p<\) 0.01), TBW [kg] (r = \(-\)0.66; \(p=\) 0.01), and MM [kg] (r = \(-\)0.65; \(p=\) 0.01), a positive medium significant correlation between resting HR vs. FM [%] (r = 0.68; \(p<\) 0.01) and FM [kg] (r = 0.60; \(p=\) 0.01), a negative medium significant correlation between resting HR vs. FFM [%] (r = \(-\)0.61; \(p=\) 0.01), TBW [%] (r = \(-\)0.56; \(p<\) 0.05), and MM [%] (r = \(-\)0.62; \(p=\) 0.01). Moreover, there was a negative, medium-significant correlation between Klonowicz COR 3' vs. FM [%] (r = \(-\)0.63; \(p=\) 0.01), FM [kg] (r = \(-\)0.59; \(p<\) 0.05), and a medium-positive correlation between Klonowicz COR 3' vs. TBW [%] (r = 0.61; \(p=\) 0.01) and MM [%] (r = 0.66; \(p=\) 0.01) (Table 3).
