Abstract

Problem statement: To quantify the effect of exhausting exercise induced muscular fatigue on functional stability. Approach: About 30 male professional athletes with mean age 23±2.1 years old, mean weight 82±1.3 kg and mean height1 81±9.7 cm were selected for participation in this study. In this study Unstable Biodex platform (level 3) used for stability evaluation. Balance performance was quantified as a stability index and the mean deflection of the platform. Running Based Anaerobic Test (RAST test) used for fatigue execution. Results: Results showed no significant (p>0.05) main effect for exercise duration in the stability index, suggesting that balance performance was maintained throughout the competition. Hence there wasn’t a significant relationship between lactate acid accumulation and variations of stability indices (r = -0/661, p<0.05). Conclusion: Therefore, the improvement of proprioception in the ankle and knee joint is recommended as a prevention role to the injuries in the abovementioned joints.
