The main findings of this investigation showed that the ARAT is a reliable and valid test to assess the lower limb reactive agility component of elite male volleyball athletes.
The SUBRAT, on the other hand, is not as reliable as the ARAT and, therefore, might not be a recommended test to assess upper body reactive agility
The SUBRAT did not have a significant correlation with the T-Test, which might be explained by the fact that the SUBRAT does not have any contribution from the lower limbs, while the T-Test evaluates the legs’ CODS.
The SUBRAT and the acceleration and the 1-RM bench press correlations are both classified as large. It is curious to observe that the SUBRAT and the 1-RM bench press showed an inverse large correlation so when one variable increases, the other one decreases.
