3D Biomechanical Analysis of the Preparation of the Long Jump Take-Off (original) (raw)

The purpose of the present study was to describe the kinematics of the long jump approach and take-off and their effect upon the flight and the landing. Three digital video cameras, were used to capture the last two strides of the approach, the take-off phase, the flight and the landing of the eight jumpers participating in the men's long jump competition at the 2006 European Cup 1st League-Group B Event in Thessaloniki, Greece, on 17 June 2006. A 3D-DLT analysis was conducted for the two final strides of the approach and the take-off and a 2D-DLT analysis for the landing. Results indicate that all participants seemed to utilise the "longer penultimate-shorter last stride" ratio. Two types of approach were revealed, the "straight forward" and the "imbalanced". These approach types did not affect the long jumping technique, but the stride angles of the last stage of the approach were highly correlated (r> .70, p< .05) with the placement of the take-off foot on the board and with the lateral flight path of the Body Centre of Mass.
