Analysis of Swimming Start Angle to the Sliding Ability of Man Crawl Swimming Style Viewed from Biomechanical Study

— The study purpose was determined the starting angle which has a further jump distance viewed from Dartfish analysis in swimming sports. The research method was used quantitative method with descriptive analysis approach. The study sample was swimming athletes totaling 3 people. The jump results from the start performed by athletes with 3 experiments were analyzed by statistical analysis and motion analysis using Dartfish software. The conclusions are (1) there are significant differences in the experiments carried out by swimmers with different starting angles resulting in different jump distances; (2) motion analysis shows that swimmer 3 in the second experiment with knee angle of 109  , slope angle of 100  , repulsion angle (elevation) of 22  , entry angle of 39  with travel time 0.33 seconds in air reaches the farthest jump distance which is 3.78 meter.
