 note = {Motion in a take-off phase of a maximal vertical jump starting from a static squat position was analyzed. Changes in torque and power of hip, knee and ankle joints were determined during the take-off phase with the help of anthropometric data, kinematic data obtained from position sensor system, and four segment mechanical model. Peak torque of hip, knee and ankle joints were 210 Nm, 194 Nm, and 213 Nm, respectively. Work done by the extensor muscles at the hip, knee and ankle joints through the take-off phase were 103 J, 113 J, and 90 J respectively. These results suggest the importance of all three major leg extensor muscle groups to increase the mechanical energy of the whole body. It is concluded that many more selective studies will be necessary before it is possible to clarify the role of each joint in the take-off phase of the vertical jump.},
