| （Xi’an University of Physical Education，Xi’an 710068，China） Abstract: By using methods for three-dimensional kinematical analysis, the authors studied techniques of LIU Hong as a women 20-meter race walking athlete in China, and revealed that she had the following defects: her stride was too short; her pace was too fast; her body center of gravity fluctuated too much; her forward tilting angle was too big; her landing angle was too big; her leg included angle was too small, her hip joint flexibility was poor; her swing was not active. The authors suggested that in future training she should mainly strengthen the strength and flexibility of her hip joint, and strive to increase the swing amplitude of her hip joint and swinging legs to increase her stride.
