Abstract

The purpose of this study was to compare the kinematic characteristics of the kick start technique at the start phase demonstrated by male elite competitive sprint swimmers and male collegiate swimmers in consideration of the performance enhancement. An elite competitive sprint swimmer and eleven collegiate male swimmers performed maximal effort during competitive swimming at the start followed by 25 m crawl swim during experimental trials. The trials were recorded using three synchronized video cameras shooting at 60 fps. Two-dimensional video analysis was performed in the sagittal plane. Calculated variables at take-off were horizontal velocity, speed, attitude angle, angle of projection, whereas those at entry were entry angle, attitude angle, angle of attack. In addition, block time horizontal coordinates for start position and 15 m time were calculated. Based on the results of this study, the kick start technique for the top competitive sprint swimmer was characterized as having shorter block time and higher horizontal velocity at take-off.
