2.5. Functional Test
The order of functional tests in each exercise test session was 1—handgrip strength, 2—Sargent’s jump, 3—upper-body explosive power (medicine ball throw), 4—attack skill, 5—service skill, 6—hand movement speed (plate tapping test), and 7—Illinois agility. Between each test, 5 min of active recovery was considered. To measure the maximum handgrip strength, a Pinch/Grip analyzer (MIE Medical Research Ltd., London, UK) was used. During the test, the elbow joint was in full extension and the shoulder was in 0-degree flexion (in standing position). The highest value that the dynamometer showed was recorded as the participants’ score. This test was performed for both hands separately and in two sets (with a 1 min interval between sets) [The Illinois test was used to measure the agility of the participants [The Plate Tapping Test (Reaction Tap Test) was used to measure hand movement speed. In this test, two yellow disks of 20 cm in diameter were placed on a flat brown surface with their centers 60 cm apart. In between the two disks, a white rectangle (30 × 20 cm) was placed. The participants were asked to place their nonpreferred hand on the rectangle and move the preferred hand back and forth between the two yellow diss over the rectangle. Two taps were counted as one cycle, and the participants were asked to complete 25 cycles as fast as possible, and the time taken to complete the 25 cycles was counted using a stopwatch. Each participant performed the test twice, and the best performance was recorded [
