The results indiated the range of the propuls- ion plase of peak ver- tical ground reaction force were 1.63 to 2.71 BW(Body Weight), peak impact impulse were 0.177 to 0.268 BW × s(Body Weight × second). The range of the landing phase of passivefor- ce were 0.44 to 1.57 BW,passive impulse were 0.019 to 0.033 BW × s.First peak vertical ground reaction force were 1.08 to 3.06BW,first peak impact impulse were 0.134 to 0.153 BW × s.Second peak vertical ground reaction force were 1.08 to 1.16 BW,second peak impact impulse were 0.417 to 0.512 BW × s.Significant increase were found in hip, knee, and ankle joint flexion as drop heiht increased. The results indiated that the load of the two high impact(F.K.L)was significantly higher than the low impact(F.K.L).It is suggested that the aerobic dancers should use joints flexion and longer action time to reduce the load.
