The purpose of this study was to improve performance of elite swimmers during the starting phase, by analysing whether the lateral entry technique is beneficial to athletes' starting. Participants’ (N=12) motion data were obtained from a 3D Performance Analysis System (Kistler 9691A1) with three cameras. Extracted 14 parameters were analysed using paired samples t-test. Differences contributing to the lateral entry performance included decrease of both entry angle and maximum depth by 1° and 0.42 m respectively (p<.01), and increase of push force by 0.08 of body weight (p<.01). The preliminary results show that the lateral technique provides a 0.06 s reduction in time to reaching the first 5 m (p<.05) compared to ordinary entry, suggesting performance improvements at start times.
