摘　　要：研究抓住世界游泳发展动态,选取16名一级大学生游泳运动员对新型游泳出发起跳器上蹲踞式出发技术开展运动特征研究。结果表明:游泳出发起跳器的使用,能够提高后摆蹲踞式技术的离台速度;但腾空高度低,水下滑行效果不好,在出发起跳器上不适宜采用后摆蹲踞式出发技术。Aiming to investigate kinematic features of knee - tuck departure techniques, this study, sticking to development of World Swimming, selected 16 college swimmers at top level to start off newly - designed starting equipments with knee - tuck techniques. The results show that ： the off - platform speed in back - swaying knee - tuck techniques is improved due to the use of new equipment. Meanwhile, maximum height of centre of gravity is less satisfied with low efficient underwater gliding effort. It is therefore not appropriate to adopt back swaying knee -tuck technique in starting equipment.
