[Purpose] The purpose of this study was to investigate differences in jumping ability and
lower limb balance ability elicited by plyometric training and vibration exercise, of
volleyball players with and without ankle injuries, which frequently occur among Korean
professional volleyball players. [Subjects and Methods] Twenty-eight volleyball players
were divided into the following groups: plyometric with ankle injury (PAI) group;
plyometric with non-ankle injury (PAN) group; vibrator with ankle injury (VAI) group; and
vibrator with non-ankle injury (VAN) group. After exercise and whole body vibration
stimulation, their vertical jumping abilities, side step, and static equilibrium ability
were measured. [Results] The vibration exercise group which had experienced ankle injuries
showed significant improvements in the sidestep test after the intervention compared to
before the intervention. In vertical jumping as well, significant improvements were
observed in the VAI group and the VAN group following vibration exercise. In the balance
ability test, significant improvesments in the PAN group and the PAI group were observed
after the intervention. According to the results of the right side, there was significant
change in the left/back side test and the right/back side test before and after the
intervention; and in the test of one-leg standing with eyes closed, there were significant
group, timing, and interaction effects. [Conclusions] The training method which
effectively improved the jumping ability of volleyball players was plyometric training,
and for balance ability improvement, whole body vibration exercise was effective.
