ON THE INFLUENCE OF AIR RESISTANCE DURING LONG JUMP
Keywords: sports biomechanics, long jump, modeling, optimisation
AbstractINTRODUCTION: The long jump consists of four phases: approach run, takeoff, flight and landing. The tasks to perform during the last five steps of the approach are contradictory – to increase velocity but to attain the optimum position for takeoff. During the flight the long jumper must compensate the big forward angular momentum about the transverse axis, generated during the approach and the takeoff (Hay, 1993). The basic flight techniques using are: “sail” (tucked position), “hang” (raising arms and extending legs), “hitchkick” (running in the air). The aim of the study is to evaluate the influence of air resistance on the flight phase.
