Decreased physical performance of lower extremity increases the risk of injury or repetitive injury. Lower extremity physical performance is objectively reflected in lower extremity motor components consisting of triple leg hop test, one leg stance test, star excursion balance test, and agility T-test. A factor associated with decreased physical performance of lower extremity is highly likely because of rising body mass index (BMI). To analyse the association of body mass index of adult athletes and the physical performance of lower extremity. Secondary data from athletes screening of Regional Exercise Center (PUSLATDA) East Java was used in this study. Analyzed variables were including BMI, triple leg hop test, one leg stance, star excursion balance test, agility T-test. Randomization technique was applied to recruit 91 proper respondents. Normality test, Spearman test for calculating the correlation between BMI and triple leg hop test, one leg stance, star excursion balance test, agility T-test was performed with the statistical significance of p?
