Abstract

Impact forces during landing in dismounts from the horizontal bar onto regulation gymnastic mats and in jumping from a height of 0.45 m onto a hard surface were measured. A two degree-of-freedom dynamic model was developed to predict the forces in landing on the hard surface. The periods of the two peaks that can be identified from experimental data were used in the determination of the system parameters. The peak forces recorded in gymnasts' landing ranged from 8.2 to 11.6 times the body weight. Maximum forces in jumping from 0.45 m, which ranged from 5.0 to 7.0 times the body weight, were accurately predicted by the model.
