Abstract

The purpose of this study was to analyze the differences in motion kinematics with a three-dimensional analysis approach between male and female athletes using track start techniques in swimming. This research uses descriptive quantitative method. The sample of this study were 46 university students, i.e., 26 males (average age: 19.2 ± 0.8 years old, height: 167.97 ± 6.09 cm, weight: 59.40 ± 7.61 kg) and 20 fameles (average age: 19.2 ± 0.8 years old, height: 161.97 ± 6.09 cm, weight: 55.40 ± 7.61 kg). The data collection process uses the 3D Force Platform, 3 Panasonic Handycams, Frame DIAZ IV 3D motion software and a set of manual markers. The results showed that from the 21 parameters of the motion kinematics analyzed, there were significant differences in the male group whose results were greater than the female group, especially in 7 parameters such as flight time, total time, height of take-off, vertical velocity of the CoM at take- off, leg power, force and time to 15m. Meanwhile, the role of leg power and force mechanics just before take-off is a key factor in the success of starting performance in swimming
