Pelvis-Upper Trunk Coordination at Butterfly Stroke and Underwater Dolphin Kick: Application on an Elite Female Butterfly Swimmer

Swimming strokes kinematics are traditionally monitored, analyzed and extracted for a small part of a race. This practice may facilitate methodological limitations due to restricting issues arising from video analysis, though it is not scientifically solid, despite the cyclic nature of swimming movements, which may justify it. Skill level, swimming speed and fatigue are just some of the factors or constraints that may interfere with the cyclic nature of swimming and therefore affect inter-segmental coordination from stroke to stroke. There are studies that describe inter-segmental coordination in swimming using up to four consecutive stroke cycles. Nevertheless, studyinG coordination especially under the perspective of dynamic systems theory demands a large number of strokes to be analyzed in order to bring out the underlying coordination pattern, accounting also for its stability over time.
