In a lift of synchronized swimming, it is important for the swimmers and coaches to clarify how to maximize height. The objective of this study was to analyze and compare the lifts by two teams (world`s top-ranked and 5th-ranked) from a biomechanical viewpoint. The primary difference of these two lifts was the posture of the base swimmer, who was just under the flyer (the swimmer projected into the air). The lifts were analyzed by observing the posture of the swimmers and conducting a simulation. The timing between each group was shifted as a parameter. In this parameter study, the eight swimmers in each team were divided into three groups; upper, middle, and lower. As a result, the higher jumping height for the 1st team was explained. In the 1st team formation, they could perform an egg beater kick with full strength since sufficient space for the egg beater kick could be secured. Large effort was not necessary for the base swimmer since the base swimmer took the upside-down squat position. The flyer of the 1st team jumped at an angle closer to the vertically upward direction due to the higher stability of the flyer herself. The flyer could jump with full strength by flexing and extending the knee joints through a large range. The swimmers of the 1st team were performing the jump motions with the best timing.
