Introduction and aim: One of the serious challenges in sports is injury prediction methods that can help prevent and reduce injuries. Therefore, the purpose of this research was to answer the question, of Do functional movement screen, Y balance, and landing error scoring system tests have the power to predict sports injuries in female student athletes? Methodology: This study was a prospective cohort study. The population of the current research was university female athletes, and the research sample was 124 female student athletes participating in the 15th Iranian Student Sports Olympiad who were evaluated in an available manner. The Y balance test, landing error scoring system, and functional movement screening test were taken from the subjects before the Olympiad, and the injuries of the athletes during the competitions were recorded by the data collection form. In order to statistically analyze the data, the logistic regression test and Pearson correlation coefficient were used. Results: The results of the research showed that a total of 26 injuries were registered during the competition in 124 subjects. None of the predictor variables had the ability to predict the criterion variable (p>0.05). Conclusion: In general conclusion based on the results of this research, it is not possible to predict general injury using functional tests.

The purpose of current study was to investigate the spatio-temporal gait parameters and knee varus angle
during walking at different speeds in young with knee varus. 18 subjects with varus deformity classified at
grade 3 of bowleg and 17 healthy subjects, volunteered to participate in this study. The following variables
include stance, swing, double support and cycle time, cadence, stride length, angle of varus at the heel
contact, midstance and toe off when walking on the treadmill at speeds of 80, 100 and 120 percent of
preferred walking speed, were measured from using the three-dimensional motion analysis system with six
optoelectronic cameras. The results of between-group tests showed that spatio-temporal gait parameters
in the varus group is similar to the normal group. Also varus angular variables in varus group, was indicate
higher values in comparison to the healthy group, but there were no significant differences. The results of
inter-group tests also showed the knee varus angle generally increases with increasing speed, that none of
the differences were not significant. According to the results, the increase in walking speed will caused to
increase knee varus angle. Therefore, walking with speed less than the normal walking speed, probably is
a suitable solution to reduce the loads exerted on the knee joint and prevention of premature osteoarthritis
in young with knee varus.
