... For the case of the circular trajectory, two families of exact solutions are obtained. ... These exact solutions allow us to obtain approximate solutions for the case of an elliptic trajectory of the waist. ... We also check the condition of keeping contact with the waist during twirling. ... Main relations We assume that the center O of a gymnast's waist moves in time according to the elliptic law x = a sin t, y = b cos t with the amplitudes a, b and the excitation frequency > 0, Fig. ...
