Effect of High-Intensity Training on the Anaerobic Power and Isokinetic Muscular Strength in the Knee Joint of finswimmers.

Purpose: The purpose of this study was to analyze the effects of high-intensity training on anaerobic power and isokinetic strength in finswimming athletes. The study focused on elite athletes registered with the Korea Underwater and Finswimming Association, specifically targeting short-distance and middle-distance male and female athletes. Research Design, Data, and Methodology: The study involved 15 finswimming athletes (9 males and 6 females) from university and industrial teams. Participants were selected based on their elite status, absence of mental and physical illnesses, and a minimum of four years of athletic experience. They voluntarily agreed to participate after understanding the study's purpose. During the research period, participants were restricted from engaging in intense exercise, smoking, drinking, and any unusual dietary or medicinal intake. Data were processed using SPSS V.26.0 to calculate mean and standard deviation, and training effects were analyzed using paired t-tests to compare pre- and post-training differences between short-distance and middle-distance groups, with a significance level set at .05. Results: The results indicated a significant decrease in the peak power per body weight for short-distance finswimming athletes, while no significant effects were observed on anaerobic power and isokinetic strength of the knee joint. Conclusion: The findings suggest the need for further research on appropriate training methods, exercise forms, and intensity for high-performing finswimming athletes. Future studies should also explore differences in training by event and gender, psychological variables, and various performance-related factors such as competition records.
