This study aimed to identify the physical condition components that significantly influence the eligibility status of karate athletes preparing for the 2025 National Sports Week (PON) Beladiri Kudus. Grounded in contemporary sport performance theory, karate performance is understood as a multidimensional construct dominated by neuromuscular, speed, and explosive capacities. A quantitative descriptive-analytic design with a cross-sectional approach was employed involving 11 provincial karate athletes (3 female; 8 male) from Jambi Province. Data were collected using standardized physical fitness assessments, including upper-body strength (push-ups), abdominal strength (sit-ups), aerobic endurance (Multi-Stage Fitness Test/VO₂max), linear speed (30-meter sprint), agility (shuttle run), lower-body power (vertical jump), and upper-body power (medicine ball throw). Descriptive statistics were applied to determine athlete physical profiles, while Spearman Rank correlation analysis was used due to non-normal data distribution (Shapiro–Wilk, p < 0.05). The results revealed significant positive correlations between eligibility status and arm muscle strength (r = 0.882), sprint speed (r = 0.860), agility (r = 0.772), leg power (r = 0.737), and upper-body power (r = 0.738). Conversely, VO₂max and abdominal strength demonstrated positive but statistically non-significant relationships. These findings empirically confirm that explosive strength, speed, and agility are dominant determinants of competitive eligibility in karate. The study provides an evidence-based foundation for prioritizing neuromuscular performance development in training programs and enhancing objective athlete selection toward PON Beladiri Kudus 2025.
