The comparative effects of four-week core stabilization and balance-training programs on semidynamic and dynamic balance

The purpose of this study was to determine the comparative effects of four-week core stabilization and balance-training programs on semidynamic and dynamic balance. Subjects were randomly assigned to one of four groups using stratified randomization for gender and activity. These groups included a control group and three experimental groups. Subjects in the three experimental groups performed their training program two days per week for four-weeks. The Biodex Stability System Test (semidynamic balance) and Star Excursion Balance Test (dynamic balance) were used for pre-test and post-test. There were no significant differences for the Biodex Stability System Test. There were significant main effects for time (medial, posterior, & lateral excursions) and interactions for time X group (posteromedial & anterolateral excursions) for the Star Excursion Balance Test. A combined core stabilization/balance-training program could be used to improve semidynamic balance, whereas a core stabilization-training program or balance-training program could be used to improve dynamic balance.
