Purpose Focusing on the force and velocity relationship, we verified the valid combinations of angular velocity and joint torque for estimations of isometric peak torque in knee extension using 2D movement analysis. [Subjects] Ten healthy males aged between 24 and 38. [Methods] Images captured by a high-speed video camera were edited, and the coordinates of the joints determined by image measurement software were entered into a dynamic model which calculated angular velocity, joint angle and torque. Valid combinations of angular velocity and joint torque were investigated at the estimated values of isometric peak torque, and the estimated and actual values were compared. [Results] The estimated and actual values of isometric peak torque had ICCs ranging from 0.61 to 0.76, and the highly compatible combinations determined using the estimated value were the peak angular velocity and peak torque. [Conclusion] In the future, we would like to investigate the validity of the estimated values with a greater number of subjects and with a limited number of loads, and investigate their compatibility with various muscle strengths.
