Abstract
Introduction and purpose: The landing error scoring system is a valid and reliable tool for functional assessment of jump-landing movement. The aim of the present study was to investigate the effectiveness of sports training on the landing error scoring system in athletes.
Methodology: Searching between 2014 and 2024 from IranDoc, Magiran, PubMed, Google Scholar, SPORTDiscus, Scopus, PEDro and (ISI) Institute for Scientific Information databases using the combination of jump-landing keywords. Landing mechanics, landing kinetics and kinematics, injury prevention, training, rehabilitation and landing error scoring system were done. A total of 88 articles related to this field were found, after reviewing and screening through the inclusion criteria, 8 articles were reviewed in full text.
Results: Various exercises, including neuromuscular, suspension, knee injury prevention, fatigue and kinesiotype, have been used to be effective on the landing error scoring system test. As a result of corrective exercises and fatigue, the experimental groups showed an improvement and a decrease in the jump-landing movement performance in the landing error scoring system, respectively.
Discussion and conclusion: It seems that in order to prevent jump-landing movement errors and possible injuries caused by it, exercises should be done that, in addition to increasing concentration and coordination in movement, make athletes resistant to factors such as danger.

Abstract
One of the factors affecting jump-landing patterns is fatigue. Fatigue is an inevitable component of physical
activity, hence the aim of the present study was to investigate the effect of functional fatigue on landing
mechanics through Landing Error Scoring System (LESS).Fourteen male college students with a mean age of
22±2 years, weight of 68.3±7.2 kg and height of 174±4 were randomly divided into two groups: experimental and
control. Effect of independent variable, fatigue, due to activities resembling athletic training or competition (6-
stations functional fatigue protocol) on dependent variable, landing mechanics, through pre test-post test was
investigated. The independent t-tests and non-parametric U-Mann Whitney test was used for statistical analysis
of data (P < 0.05). The results of the present study indicated the relationship between fatigue and attenuation of
landing mechanics (P=0.02), and therefore an increase in injury risk. Also it was shown that the effect of fatigue
on decreasing knee flexion angle at initial contact was significant (P=0.022). With regard to the results, it can be
concluded that functional fatigue induced by physical activities can alter landing mechanics, and increase loading
of lower extremity joints, particularly the knee. So the risk of injury in these joints may be increased.
