- Abstract
- Objective: The purpose of this study was to show the temporary effects of performing jumping lunges on a sand surface on static balance and dynamic balance.
Design: Randomized controlled trial.
Methods: Twenty healthy subjects volunteered in the study and was randomly assigned into either the sand group (n=10) or the control group (n=10). The subjects in the sand group performed jumping lunges on a sand surface and the subjects in the control group performed jumping lunges on a firm surface. The intervention was performed for 3 sets of 8 repetitions by both groups. To measure static balance, the force plate was employed to measure the center of pressure (CoP) area, and the CoP velocity during one-legged standing. Anterior, postero-medial, postero-lateral movements was assessed using the Star Excursion Balance Test (SEBT) to measure dynamic balance.
Results: After the intervention, the sand group showed statistically significant improvements on all variables (CoP area, CoP velocity) in static balance (p<0.05). There were statistically significant changes in CoP area and CoP velocities between the two groups (p<0.05). In the sand group, there were significant improvements in the postero-medial and postero-lateral directions (p<0.05) except for anterior direction on dynamic balance. In the control group, there was a significant improvement in the postero- lateral and anterior directions (p<0.05). In comparison of the two groups, there was no statistically significant improvement in all variables.
Conclusions: This study demonstrated that performing jumping lunges on a sand surface was effective in improving static and dynamic balance temporarily.
