The effect of four weeks dynamic warm-up on static and dynamic balance and proprioceptive receptors in skilled female Gymnast

  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 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). 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). 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
