There is an evident lack of studies examining the factors associated with reactive agility performances. The aim of this study was to evaluate the association between anthropometrics, body composition, jumping capacity, reactive strength, and balance with a stop-and-go change of direction speed (CODS) and reactive agility. The total sample comprised 39 male (body height: 182.95 ± 5.19 cm; body mass: 80.66 ± 7.69 kg) and 34 female (body height: 171.45 ± 6.81 cm; body mass: 61.95 ± 6.70 kg) college-level athletes (21.9 ± 1.9 years of age). The variables included body height, body mass, the percentage of body fat (BF%), balance as measured by an overall-stability index, the countermovement jump (CMJ), a reactive-strength index (RSI), stop-and-go reactive agility, and stop-and-go CODS. To define the associations between motor and anthropometric variables with CODS and reactive agility, the participants were clustered into three achievement groups based on their CODS and reactive agility performances. The ANOVA showed a significant difference between the CODS-based achievement groups for the CMJ (F test = 3.45 and 3.60 for males and females, respectively; p &lt; 0.05), the RSI (F test = 6.94 and 5.29 for males and females, respectively; p &lt; 0.05), and balance (F test = 3.47; p &lt; 0.05 for males). In females, the reactive agility achievement groups differed significantly in the RSI (F test = 6.46; p &lt; 0.05), the CMJ (F test = 4.35; p &lt; 0.05) and BF% (F test = 4.07; p &lt; 0.05), which is further confirmed by discriminant canonical analysis (Can R = 0.74; p &lt; 0.05). The results confirm the need for independent evaluation and training for both CODS and reactive agility performance in sports.
