Experiments were conducted using three-dimensional motion capture technique on single person jumping. Seventy three test subjects participated in the experiments and each of them conducted four test cases of different frequencies. Thirty nine markers were attached to each test subject during the test. The jumping frequency was simulated by a metronome. The time lag between metronome time and landing time was proposed as the coherence factor of rhythmic jumping. The statistical analysis of experimental data shows that probability distribution characteristics of coherence factor can be described as the combination of uniform distribution and Beta distribution, which are corresponding to individual random jumping and coherent jumping in crowd respectively. The parameters of factor model functions are determined by experimental results. Simulation of crowd jumping load is carried out by combining the coherence factor with single random jumping load model. The simulating method is proved to be reasonable by application examples.
