Effect of Fatigue on Biomechanical Parameters and Incidence of Injury in Selected Movements of Healthy People: A Systemic Review

Abstract

Background and Aims: Fatigue is one of the factors that can affect different movement patterns and change its nature biomechanically. Since fatigue is one of the essential issues in the study of various movements and the possibility of injury incidents, the study aimed to review the studies on effects of fatigue on the biomechanical parameters and the incidence of injury in the selected movements of healthy people. Methods: By searching related articles in validated scientific databases and based on predetermined research criteria, 50 studies were selected as the final articles for the present systematic review. Results: Different articles have used different methods to apply fatigue. A review of studies has shown that, in general, fatigue can negatively affect the proprioception, coordination of movement and reaction time, and subsequent control of movement, disturbing control of the balance and making healthy people susceptible to injuries. Also, fatigue, as one of the essential factors in falling, leads to decreased muscle strength, reducing neuromuscular responses. These changes can increase the risk of falling, especially in the elderly. In the case of various sports movements, fatigue is one of the most important factors in the disorder and decreased exercise performance, which causes changes in the movement pattern and increases the likelihood of injuries, significantly lower limb lesions, such as ACL injury in movements such as jump-landing. Conclusion: Considering the increased likelihood of injury following fatigue in healthy people, this factor is necessary during various movements. As the level of exhaustion may alter the biomechanical pattern of various movements, this parameter should be considered as a controlling factor at the time of data collection.
