Abstract

Background: This study investigated the effect of support surface quality, stable vs unstable, for 6-week
long squat exercise program on vertical jump performance.
Method: The subjects were 24 healthy students who agreed to participate in this study. They divided into
stable support surface group and unstable support surface group randomly. The squat exercise was performed
three times of a week for 6 weeks. The height of each jump was measured by the height marked on the grid
paper with the middle finger of the subject. Muscle strength was used to measure maximum voluntary
isometric and isotonic contraction during knee extension. Balance (eyes-opened and eyes-closed one-leg
standing balance tests) was performed alternately on the right and left legs.
Results: Vertical jump was significant difference stable support surface group with unstable support surface
group.
Conclusion: These results indicate that vertical jump of stable support surface group was more improved
than unstable support surface group.
