PURPOSE: Previous research suggests that a loss in excess body weight could potentially lead to a substantial improvement in overall balance in previously obese and overweight individuals (Maffiuletti et al., 2005). However, very few studies have evaluated balance performance before and after weight loss due strictly to exercise. The purpose of this study was to evaluate if an exercise intervention aimed at weight loss could lead improvement in standing balance. METHODS: Fifteen overweight, but otherwise healthy adults (9 females, 6 males) (age: 23.5 years; height: 1.70 m, starting body mass: 92.8 kg) participated in this study. Balance performance was assessed with a sensory organization test (SOT) prior to and after a 10-week exercise intervention. Center of pressure (COP) sway velocities and root-mean-square (RMS) sway were analyzed using a repeated-measures ANOVA and potential relationships with changes in body mass was evaluated employing a Pearson correlation. RESULTS: Results from the SOT COP sway parameters revealed significant differences in the eyes closed (EC) for anterior-posterior sway velocity (AP VEL) (p = 0.006), and in the eyes open sway referenced (EOSRV) conditions for AP VEL (p = 0.048). Post hoc pairwise comparisons for both variables revealed significantly lower postural sway in post-intervention evaluation versus pre-intervention. In addition, there was shown to be a significant correlation between degree of weight change and the following variables: EOSRV medial-lateral (ML) VEL (p = 0.002), EOSRV ML RMS sway (p = 0.011), eyes open sway-referenced platform (EOSRP) ML RMS sway (p = 0.029), EOSRP AP RMS sway (p = 0.049), eyes closed sway-referenced platform (ECSRP) ML VEL (p = 0.003), ECRSP ML RMS sway (p = 0.036). CONCLUSIONS: The results of the current study suggest that improved balance performance can result from an exercise intervention without any directed balance exercises. This could especially be true in situations where the somatosensory system plays a greater role in maintaining balance.
