### Acute Effects of Complex Training  
Table 3 presents the characteristics of studies that analyzed the acute effects of complex training. Table 4 shows the results of studies analyzing the acute effects of CT on performance in basketball players. The table presents the values obtained in the tests used by the studies following the acute application of CT, along with the reported effect size and \(p\)-value (taken directly from the studies). The studies evaluated the acute impact of CT through a countermovement jump (CMJ) [30; 33] and a single-leg jump (SLJ) [30] to assess jump ability, focusing on factors such as height. Agility performance was assessed using the Shuttle Test [33] and the modified t-agility test (MAT) [30]. Sprinting performance was measured using 10-30-m linear sprint tests [29]. The acute effects of CT were analyzed immediately [29; 30; 33] and after 5 min [29]. \begin{table}
