Abstract

Unstable surface training and traditional resistance training has been proven to effectively enhance balance and stability. Despite the similar overload mechanism on stability, comparison between effectiveness unstable surface training (UST) and unilateral loading resistance training (ULRT) have not been done. Hence the objective of the present study is to investigate the effects of unstable surface training and unilateral loading resistance training on postural stability. 26 active TARUC students (13 males, 13 females) were recruited in the study. Participants were distributed into UST and ULRT groups and underwent a 6-weeks training program. Pre-test and post-test were conducted before and after the training intervention using BIODEX balance system. Stability and sway indexes on anterior-posterior and medio-lateral plane were collected and analyzed using 3-way ANOVA, Tukey Post Hoc comparison. Overall stability index showed improvements in both unstable surface group (p = 0.01) and unilateral loading resistance training group (p = 0.03). However, no between group differences were detected. The MLSI in UST group showed better improvements compared to APSI in ULRT group, and MLSI in ULRT group also showed better improvements compared to APSI in ULRT group. Results suggested that medio-lateral plane training stimulates better improvements on overall stability index (OSI) in both training modalities.
