This study examines the relationship between cardiac performance and physical performance in highly skilled judo athletes during training. A sample of 20 elite male judo athletes was administered cardiovascular measures, including resting heart rate, maximum heart rate, and VO₂ max, as well as physical performance tests measuring grip strength, vertical jump height, agility, and endurance. The results showed a strong correlation between VO₂ max and several physical attributes, including endurance (r = 0.82), agility (r = -0.58), and explosive power (r = 0.55). A decrease in resting heart rate was also associated with better strength and power performance. No significant correlation was found between maximum heart rate and physical performance. These findings highlight the central role of aerobic capacity in overall athletic performance and suggest that improving cardiovascular fitness can improve judo-specific physical abilities. The study provides valuable insights into optimizing training protocols for elite judo athletes.
