Effect of Integrative Neuromuscular Training on Lower Limb Functional Asymmetry and Balance Ability of Deaf Table Tennis Players

Objective:This paper used a pre-post test to quantify the effect of integrated neuromuscular training on lower limbs functional asymmetry and balance ability of Chinese deaf table tennis athletes. It was hypothesized that integrated neuromuscular training could significantly reduce the Chinese deaf table tennis players' s lower limb functional asymmetry (asymmetry index of height and power of single-legged vertical jump, side jump and forward jump) and improved balance ability (movement speed, average moving distance, total moving distance, maximum distance of X and Y axes) . Methods:Sixteen athletes were divided into experimental group and control group, the experimental group were subjected to integrated neuromuscular training intervention for 8 weeks, the control group athletes performed routine strength training. Before and after the experiment, the single-leg vertical jump, side jump and forward jump test were completed with Myotest System, and the single-foot balance test was completed with the Good Balance System. the paired sample t test were used to determine differences between pre-post test results in group, and the independent sample t test were used to determine differences between groups test results. Results: by compared with the control group, the pawer asymmetry index of vertical jump and forward jump of Chinese deaf table tennis athletes had a very significant decreased (P<0.01) , the height asymmetry index of vertical jump, side jump, forward jump and side jump power had a significantly decreased (P<0.05) , There was no significant change in the control group. In addition to left foot X-axis movement speed, maximum displacement of the Y-axis and the total distance from the Y axis of the right foot were significantly decreased (P<0.05) , while other indicators had a very significant decrease (P<0.01) . There was no significant change in the control group. Conclusion: The integrated neuromuscular training can effectively decrease the lower limbs functional asymmetry and improve the balance ability of Chinese deaf table tennis athletes. Suggestion: In practice, Deaf table tennis player or deaf people should be emphasis prevent bilateral asymmetry of lower-limb, The integrated neuromuscular training can be used as a reference measure to improve lower-limb exercise performance, functional asymmetry of the lower limbs and balance ability for deaf people or table tennis athletes.
