摘要：Balance is a necessary aspect of the physical condition in football, serves to stabilize the multiple movements or simultaneous, facilitate the mastery of hard technic, orientation towards the opponent and the environment. This study aims to determine whether there is a correlation BMI and leg muscle strength with balance. Type correlation study, the test a survey method. Population players SSB Lowo Ijo Kab Grobogan junior high / high school amounted to 23 people with a total sampling technique. The research variables is BMI, leg muscle strength, and balance. Test instruments, roll meters and digital scales, back and leg dynamometer, and modifications bass test. Analysis of data using correlation and regression. Analysis prerequisite test 1) Kolmogorov-Smirnov test for normality tests, 2) linearity test, 3. multicolinierity test and heterokedastisitas test. Results of calculation of correlation (r) = 0882 and p = (0.00 <0.05). Means there is a significant correlation BMI with balance. 2) (r) = 0909 and p = (0.00 <0.05) means that there is a significant correlation a leg muscle strength with balance. 3) (R0) = 0.842 and p = 0.00 <0.05. Means there is a significant correlation between BMI and leg muscle strength with balance. Conclusions is significant correlation BMI and leg muscle strength with balance. SSB suggested the manager should pay more attention to BMI, physical condition leading to leg muscle strength training and balance exercises.
