Background and Aims: Mental fatigue usually occurs after prolonged cognitive activities that decrease cognitive function and lead to changes in motor coordination. The purpose of the present study was to investigate the effect of mental fatigue on balance, lower extremity function, and landing biomechanic changes in amateur male athletes.
Materials and Methods: In the current quasi-experimental study, 35 amateur male students volunteered. Mental fatigue was induced by 45 minutes of cognitive activity (Stroop test). Before and after mental fatigue, the followings were evaluated: dynamic balance using Y-Test, semi-dynamic balance using Lafayette Stability Platform, knee proprioception using Inclinometer, lower extremity function using LEFT Test, landing mechanic using Balance Error Scoring System, and Jump-Landing skill film assessment using AutoCAD and Kinovea software. Data were analyzed making use of SPSS software (version 22) and running paired sample t-test at the significance level of 0.05.
Results: The results of Paired sample t-test showed that lower extremity function (P=0.0001), dynamic balance (P=0.0001), semi-dynamic balance (P=0.0001), and knee proprioception (P=0.0001) decresed and landing biomechanics (P=0.004), which have been reported as the predictors of lower extremity injuries risks after undergoing mental fatigue, increased significantly.
Conclusion: According to the results, significant decrease in balance, lower extremity function factors, and increased landing mechanics of amateurs after mental fatigue have been shown, and injury prevention experts should study the strategies for the prevention of mental fatigue.
