The purpose of this study was examined effect of neck muscles fatigue on dynamic balance control in athlete and non-athletes females. 48 healthy females (24 athletes and 24 non-athletes) in 4 athlete and non-athlete control and experimental groups for 3 easy and 3 difficult directions of SEBT ( with age:22/33±1/54 years, weight:57/15±6/52 km, height: 162/37± 5/04cm) participated in this study. We measured dynamic balance control by star excursion balance test (SEBT). For produce fatigue in neck muscles, subject repeated to elevate her shoulders (until Borg scale=15) while hold a dumbbell with 30% of her 1RM. We used ANOVA and Tukey for data analysis (P≤0.05). The results showed a significant different between balance of 4 groups after the neck muscle fatigue in difficult directions (P꞊0/0001, F=12/51,) and easy directions (P꞊0/0001, F=10/13)and the reach distances decreased after the fatigue protocol in experimental groups. Therefore we suggest to coaches that note for increase the neck muscles endurance.
