BEKLENEN POSTÜRAL AYARLAMALAR ARTIŞINDA İŞİTSEL UYARANLARIN GÖRSEL UYARANLARA GÖRE DAHA BÜYÜK ETKİSİ

Purpose: The role of visual stimuli as the primary stimulus and effect auditory before external perturbation on Anticipatory Postural Adjustments (APAs) releases has been investigated, but which type (auditory or visual) a more significant initial APAs release, needs to be investigated. So, this study aimed investigate visual-auditory contributions presentation release at different time intervals.
 Methods: Participants in were fourteen physical education students (Meanage 22.4 ± 2.14 years) exposed five trials an audible (80 dB) while standing Biodex balance sheet. Then, 1.4 seconds after presenting stimulus, was applied. Electromyography (EMG) activity postural muscles recorded during all trials. extracted intervals -100 50 ms (APA1), 200 (APA2), 350 (APA3). mixed ANOVA repeated measures analysis variance with Bonferroni correction test used for data analysis.
 Results: results showed that increased muscles. According these results, APA3 greater than APA2 APA1(P≤0.05). Also, (P≤0.05).
 Conclusion: Generally, researchers concluded providing APA healthy young girls. Therefore, it is suggested order prevent imbalance maintain balance, appropriate intensity can used. Furthermore, subsequent research topic could include comparing under influence men women, athletes non-athletes, individuals mobility impairments.
