the authors performed 3d photographic measurement on the technical moves of zhang wen-xiu as an excellent female hammer thrower in china to get relatively comprehensive body movement data by using two jvc3000 high-speed cameras, screened and analyzed the data by using spss software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sustainable accelerating power was not high.
