Ski-Jump performances were investigated in this study. Most of the difficulties for studies were to get the physical data. And few papers have previously been reported. The times of approaching and flight, and flight distance are measured. The performances of the take-off are taken with 16mm camera and the style points are recorded. Nine excellent Ski-Jumpers expected to be as the Olympic contenders were chose as subjects. In the conclusion, significant relationships were pointed out as follow; Flight distance (X) and Flight time (Y) Y= 0.041X +0.143 r = 0.92^<**> Approach time (X) and Flight time (Y) Y =-0.75X+ 5.52 r = -0.64^* Flight distance (X) and Approach time (Y) Y= -0.023X +5.36 r = -0.60 The importances of timing on take-off, flight direction, muscle power and fighting style should be emphasized from those data.
