We measured aerodynamic forces acting on real jumping flights in the take-off phase as well as a quasi-steady flight phase. The frame rate was 250 frames/s. It is concluded that the present aerodynamic force data derived from the image analysis are found to be in fair agreement with existing wind tunnel data for the cases of jumping flights in the quasi-steady flight phase. The aerodynamic data in the cases of relatively large forward leaning angle, which is typical in the initial phase of a jumping, could also be obtained. The lift in the take-off phase is relatively larger when compared with the quasi-steady flight phase.
