Abstract: 
Objective: To study the correlation between dynamic balance ability and lower limb muscle strength of university students.
Methods: 50 students of Zunyi Medical University (23 boys and 27 girls) were selected as the subjects. The dynamic balance ability of university students was tested by the YBT test system. Isokinetic muscle strength tester tests knee flexion and extension muscle strength under different angular velocity conditions.
Results: 1) At different angular velocities, there was a moderate positive correlation between knee flexion and extension muscle strength and YBT reaching all directions. Only when the angular velocity was set to 200° / s, there was a low positive correlation between knee flexion muscle strength and the front side of the YBT test. 2) There is a more significant correlation between the maximum distance of each direction of dynamic balance and the peak torque of knee extensor than that of flexor.
Research conclusions: For university students, there is a significant indigenous correlation between the directions of YBT arrival, and the correlation between the posterolateral and the posterolateral is stronger. The stronger the lower limb muscle strength is, the better the dynamic balance ability is, and the correlation between dynamic ability and knee extensor muscle strength is higher, which may be related to the fact that knee flexion control balance can more effectively activate knee extensor muscle group. University students generally have bilateral asymmetry of the lower limbs.
