## 3 Results  
Among the main results for body weight are the following: significant differences were found in favor of male professional BPs (F = 0.530; \(p\) = 0.020) and height (F = 0.001; \(p\) = 0.001) compared to female professional BPs. However, no significant differences were found for body mass index. Significant differences were reported in body composition regarding male professional BPs in body fat percentage (F = 0.052; \(p\) = 0.000) and fat-free mass (F = 12.864; \(p\) = 0.000) compared to female professional BPs. In physical performance, significant differences were reported in CMJ in favor of male professional BPs (F = 19.138; \(p\) = 0.000), ball throwing (F = 0.903; \(p\) = 0.000), and MIHS dominant hand (F = 1.548; \(p\) = 0.000) and MIHS non-dominant hand (F = 0.249; \(p\) = 0.000) compared to female professional BPs. However, no significant differences were reported in 10 m sprint (F = 3.822; \(p\) = 0.371), 10 m ball sprint (F = 2.365; \(p\) = 0.142), 20 m sprint (F = 0.753; \(p\) = 0.915), and 20 m ball sprint (F = 1.081; \(p\) = 0.301) between male professional BPs and female professional BPs. These results are presented as mean and standard deviation in Table 1.  
Figure 1A,B show the correlations between fat-free mass and physical performance in professional basketball players. A significant positive and large correlation was found between fat-free mass with CMJ (r = 0.760; \(p\) < 0.0001; ES = 1.43, _large effect_), MIHS dominant hand (r = 0.783; \(p\) < 0.0001; ES = 1.50, _large effect_), and MIHS non-dominant hand (r = 0.805; \(p\) < 0.0001; ES = 1.85, _large effect_), in addition to significant positive and moderate correlation with throwing ball (r = 0.586; \(p\) = 0.001; ES = 0.56, _moderate effect_), 10 m ball sprint (r = \(-\)0.510; \(p\) = 0.007; ES = 0.35, _small effect_), and weak correlation 20 m ball sprint (r = \(-\)0.143; \(p\) = 0.046; ES = 0.16, _insignificant effect_). In contrast, no significant correlations were observed between fat-free mass and 10 m sprint (r = \(-\)0.227; \(p\) = 0.263; ES = 0.04, _insignificant effect_) and 20 m sprint (r = \(-\)0.349; \(p\) = 0.079; ES = 0.01, _insignificant effect_).

MIHS: maximal isometric handgrip strength. \begin{table}
