Abstract
Recent research indicates unstable surface training (UST) can benefit an individual's balance over time. Studies have been conducted in the areas of muscle activation on a number of different modalities, including Swiss Balls and Bosu Balls. However, few studies have been conducted to interpret the manufacturer's claims that it can be effectively used to increase balance and stability. The purpose of this study determined the Indoboard's ability to successfully improve muscle activation of the core and legs and improve the development of functional balance over time. Over a six-week period, subjects participated twice/week in a 10-min continuous protocol using the Indoboard as an unstable intervention. A control group on stable ground performed the same protocol in an effort to determine the modalities' effectiveness over the length of this study. Twenty four subjects (12 male/12 female) from the University of West Florida with no background experience in UST completed the study. No statistical significance (p < 0.05) on electromyographic (EMG) activity was observed between groups. There was a trend toward higher EMG activity observed in the intervention group. This was noticed for both the Army Personal Fitness Test (APFT) Sit-up Test and Stork Stand Tests administered pretest and posttest.
