EFFECT OF SHOULDER STRENGTH ON THE FLIGHT DISTANCE IN THE STANDING LONG JUMP
Keywords: joint torque, dynamic simulation, optimization, long jumping
AbstractThe purpose of this study was to identify the effect of different maximum shoulder joint force to the standing long jump distance. A five-segment model connected by frictionless hinge joints in plane motion was established for simulating the flight phase, and was driven by joint torques. The results show that jump distances are generally linearly related to maximum shoulder joint torque from 20 to 160 Nm. Further increase in shoulder joint strength fails to enhance the performance. Furthermore, a complete model combining both the ground contact and flight phases of the standing long jump should be used in future studies.
