The Use of Variable Rhythm Exercises and Their Impact on Stroke Timing for Elite National Team Athletes in Quadruple Kayak

Abstract

This study aimed to develop variable-rhythm exercises for the advanced national team athletes in the quadruple kayak (K4) and to investigate the impact of these exercises on stroke timing. The researchers employed an experimental methodology with a sample of 8 athletes, implementing an 8-week training program that incorporated variable-rhythm drills. Electronic sensors and motion analysis software (Dartfish) were used to measure stroke synchronization, timing accuracy, and kayak speed , The results revealed statistically significant differences between pre- and post-tests. Stroke synchronization improved by 18%, timing accuracy increased by 2 points, kayak speed enhanced by 12.5%, and the time to complete a 1000-meter distance decreased significantly. These outcomes are attributed to the variable-rhythm exercises’ ability to enhance neuromuscular coordination and optimize energy efficiency. The study recommends integrating these exercises into training programs, supported by technology to monitor progress and refine performance metrics.
