Football or Soccer is the world's most popular sport. There are over 240 million registered players worldwide and many more recreational football players. The knee is a complex joint with many components making it vulnerable to a variety of injuries. In this study we have investigated the effect of dynamic balance on injured and uninjured male professional football players. Cross sectional comparative study design used for this research .Total hundred and six (106) male professional football players were selected for the study as per the inclusion criteria. Eighty one (81) right and left knee uninjured samples and forty five (45) right and left knee injured were collected from 106 subjects. Star excursion balance test (SEBT) used to evaluate dynamic balance at eight directions. Dynamic balance of lower limbs measured at anterior, anterior-medial, anterior-lateral, medial, lateral, posterior, posterior-lateral, posterior-medial for injured and uninjured groups. Data analysis did to find out the significant difference in dynamic balance among the groups. Comparative study performed by independent t test for dynamic balance between knee injured and uninjured groups. P0.05 was considered as significant difference in effect for the study. The means of knee injured and uninjured groups were 55.90 and 57.21 respectively with t value 1.96 for degree of freedom 1006. The study found that dynamic balance has significant effect on knee injury, with P0.049*. The study concluded that dynamic balance has significant effect on knee injury. Dynamic balance of lower limb was more among uninjured male professional footballers than injured players.
