Purposes: This study aims to investigate the factors contribute to higher on-water vertical jump among female water polo players, firstly, to investigate the difference between different styles of jump to the height of on-water vertical jump, secondly to investigate the difference of trials to the height of on-water vertical jump, and lastly to examine the correlation between experience and the height of on-water vertical jump. With the development of water polo, women water polo has been well-developed and include in major international competitions. On-water vertical jump has been a fundamental skill to accomplish which players have to maximize their elevation for passing, shooting and blocking. Methodology: Twenty female water polo players aged18-39 conduct the on-water vertical jump test with different shoulder movement (abduction, adduction & extension) and single-arm and double-arm downward motion of 3 trials. Theon-water vertical jump height is recorded and tested in inches-scale vertical jump tester. Experience of the players are interviewed. The style of underwater arm propulsion, leg and limb movement is observed. Results: Under repeated measures ANOVA, the main effect of styles is significant. (p < 0.001) Followed up by post-hoc pairwise comparisons using Bonferroni criterion, Significant difference between single-arm and propulsion in on-water vertical jump and other styles are found.(p <0.05) Significant difference are also found between trial 1 and other trials. (p <0.05) Under Pearson coefficient, the height of vertical jump of styles are positively correlate with experience. (p <0.05 ) Experience can predict the height of on-water vertical jump suggested by linear regression. Conclusion: On-water vertical jump was found to be higher with double arm downward propulsion with subsequent trials. It correlates positively with players' experience. Further research is needed for the underwater movement including the angle of leg and limb during elevation
