Abstract
[Purpose] The relationships of agility with the muscles surrounding the knee joint were investigated. [Subjects and Methods] We measured the agility of 12 healthy adults using the Ten Step Test (TST), and investigated its correlations with maximum torque and the amount of work done while measuring isokinetic knee joint flexion and extension strengths at angular velocities of 60, 180, and 300 deg/s. [Results] Significant negative correlations were found between TST and the maximum torque of the low speed range, and the full speed range of the amount of work. [Conclusion] The results suggest that TST is a measure of agility, and is related to the low speed range maximum torque of the dominant leg, and contraction endurance.
