Exploring the Correlation between Physical Fitness and Kinematic Parameters in Butterfly Stroke among Physical Education Students

The study aimed to investigate the potential relationship between physical conditioning and several kinematic variables associated with the butterfly stroke, specifically butterfly swimming arm stroke length, frequency, and average swimming speed over 25m.The study sample comprised twelve proficient butterfly swimmers who were students enrolled in swimming courses within a physical education faculty.Data were collected through a pre-designed physical condition description test.The test items used in this study were categorized based on the five dimensions of physical fitness, namely muscular strength, endurance, speed, flexibility, and agility, which were employed to assess the participants' physical states.The statistical analysis of the study was conducted by the researcher using various statistical variables, including averages, standard deviations, and the Pearson correlation coefficient.The following kinematic variables were analyzed based on this data: stroke length, stroke frequency, and swimming speed.The results of the study revealed a positive correlation between the muscle strength state and the average stroke length of the arms during butterfly swimming.Additionally, a positive correlation was found between speed and the stroke frequency rate, as well as swimming speed.In light of these findings, the researcher recommends that swimming courses should prioritize the enhancement of muscle strength and speed elements to improve the kinematic variables associated with butterfly swimming among students of the Faculty of Physical Education.
