This study aimed to investigate the influence of shoe heel height and muscle fatigue on static and dynamic balance in young women. Thirty women who were used to wearing high heels volunteered to participate in this study. The shoe heel heights were 0 cm and 7 cm. And ankle plantar flexor fatigue was experimentally induced. Static and dynamic balance were measured using the one leg standing test (OLST) and the star excursion balance test (SEBT) in anterior, posteromedial, and posterolateral directions, respectively. Values in the OLST (shoe heel height 0 cm, $28.83{pm}3.24$ sec to $26.12{pm}6.13$ sec; and 7 cm, $24.75{pm}7.09$ sec to $16.86{pm}9.32$ sec) and the SEBT in anterior (shoe heel height 0 cm, $71.02{pm}4.57%$ to $69.50{pm}3.66%$; and 7 cm, $64.17{pm}3.53%$ to $59.61{pm}4.06%$) and posteromedial (shoe heel height 0 cm, $92.01{pm}5.61%$ to $90.38{pm}7.10%$; and 7 cm, $83.09{pm}7.29%$ to $76.83{pm}9.28%$) directions were significantly reduced when fatigue-inducing exercise was performed (p<.05). Furthermore, within these parameters, there were significant interaction effects between shoe heel height and fatigue condition (p<.05). These findings suggest that shoe heel height and muscle fatigue contribute to some changes in static and dynamic balance in young women, probably leading to negative effects on physical function during a variety of activities of daily living.
