This study aimed to investigate the influences of age, height, weight, BMI, lean body mass, and fat mass on static balance performance of female college athletes. The body composition and balance stability of one hundred and three female athletes (19.5±1.2 years, 164.7±5.7 cm, 57.3±8.7 kg) were assessed by a bioelectrical analyzer and the Biodex balance system, respectively. For the later assessment, overall stability index (OSI), anterior-posterior index (APSI), and medial-lateral index (MLSI) were measured. Data were analyzed with the Pearson product-moment correlation coefficient and stepwise multiple regression by using SPSS18.0. The results showed that weight, BMI, lean body mass, fat mass were all positively correlated with the three stability indexes. Stepwise multiple regressions revealed that weight was the most predictable factor for OSI and APSI, accounted for 23.2% and 14.0% of the variance. Lean body mass was more predictable than fat mass, accounted for 17.6%, 11.2%, and 15.2% of the variance of OSI, APSI, and MLSI, respectively. These results indicate that weight and lean body mass are critical for static balance. It is suggested that the two factors should be taken into consideration when assessing the balance ability of athletes.
