#### 3.4.2 Moderator Variable Analysis on Participant Type  
For speed, moderator variable analysis identified significant effects for athletes (18 comparisons from six studies; \(SMD=0.265\); 95% CI = 0.110 to 0.420; \(p=0.001\); \(I^{2}=0.0\%\); Figure 2), and a funnel plot indicated potential asymmetry with two imputed values, and this bias was additionally observed in the [PERSON]'s regression test ([PERSON]'s \(\beta_{0}=4.518\) with \(p=0.008\); Supplementary Figure S4). However, no significant effects appear in moderately trained adults (two comparisons from two studies) and healthy adults (five comparisons from three studies) (Supplementary Table S4). For endurance, positive effects of compression garments were observed for moderately trained adults (11 comparisons from \begin{table}

Table 2: _Cont._four studies; _SMD_ = 0.219; 95% CI = 0.079 to 0.358; \(p\) = 0.002; \(l^{2}\) = 0.0%; Figure 3). A funnel plot indicated potential asymmetry with four imputed values, and this bias was additionally observed in the [PERSON]'s regression test ([PERSON]'s \(\beta_{0}\) = 5.064 with \(p\) = 0.021; Supplementary Figure S5). However, compression garments failed to improve endurance in athletes (20 comparisons from 10 studies), highly trained adults (two comparisons from two studies), and healthy adults (one comparison from one study) (Supplementary Table S4). For functional motor performance, the analysis revealed significant positive effects for moderately trained adults (25 comparisons from four studies; _SMD_ = 0.171; 95% CI = 0.063 to 0.279; \(p\) = 0.002; \(l^{2}\) = 0.0%; Figure 4), and a funnel plot showed minimal publication bias, and this bias was additionally observed in the [PERSON]'s regression test ([PERSON]'s \(\beta_{0}\) = 16.019 with \(p\) = 0.0004; Supplementary Figure S6). However, no significant effects appeared in athletes (20 comparisons from six studies), highly trained adults (one comparison from one study), and healthy adults (12 comparisons from four studies) (Supplementary Table S4). For remaining power and strength, and sport-related performances, moderator variable analyses failed to report any significant effects depending on different participant types (Supplementary Table S4).
