Purpose: The aim of this study was to investigate the effect of four weeks dynamic warm-up on static and dynamic
balance and proprioceptive receptors in skilled female Gymnast Methodology: For this purpose, 16 skilled female
gymnasts (mean age 9.62±1.45 years, height 130 ±15.62 cm, weight 28.24 ±8.52 kg and BMI 16.27±1.46kg/m2) were
selected and divide into two groups [general warm-up (control), and dynamic stretching] randomly. The first
protocol included a 10 minute jogging, and the second protocol consisted of jogging and dynamic stretching in
muscles used in performing the skill. Subjects were tested before and after acute protocol and four weeks as the using
different protocols. The indicators of the equilibrium of) anterior-posterior internal-external) in four static (with
two legs, and with one leg) and dynamic situations (with two legs and one leg) by removing visual input were
investigated. Balance assessed with dynamometer system equipped with 7 cameras and Kistler force plate.
Statistical analysis of data was performed through ANOVA and the Bonferroni post hoc test at significance level
of (p≤ 0.05). Results: The results of this study showed, a significant increase in dynamic balance with both feet
and a feet by removing visual input in a state of equilibrium with a dynamic warm-up protocol after four weeks
(p=0.001 Also Static balance on two legs and one foot with a dynamic warm-up protocol was significantly
increased after four week dynamic protocols respectively (p=0.001, p=0.005). Conclusion: Since the removal
of visual inputs can lead to a dysfunction in the postural sway control, Use a dynamic warm-up exercises
demonstrated in female gymnast that the fluctuations are significantly reduced compared to the control group in a
way that improves there in the balance performance.
