Abstract
Muay Thai is an intermittent, high-intensity combat sport that requires repeated explosive actions supported by both anaerobic and aerobic energy systems. Although previous studies have described several physiological characteristics of combat sport athletes, limited evidence has examined the integrated relationships among neuromuscular performance, anaerobic capacity, aerobic fitness, and body composition in youth Muay Thai athletes. Therefore, this study aimed to investigate the interrelationships among explosive lower-limb performance, anaerobic capacity, aerobic capacity, and body fat percentage in nationally competitive adolescent Muay Thai athletes. Twenty-three youth athletes participated in this cross-sectional study. Explosive performance was assessed using a vertical jump test. Anaerobic capacity was evaluated using a 30-s Wingate test from which peak power and mean power were obtained. Aerobic capacity (VO₂max) was estimated using the 20-m multistage shuttle run test, and body fat percentage was determined using a four-site skinfold protocol. Pearson correlation coefficients with 95% confidence intervals were calculated to examine relationships among variables. The results showed that vertical jump performance was positively associated with Wingate peak power (r = 0.662, p = 0.001, 95%CI [0.344, 0.844]). Wingate mean power was positively correlated with VO₂max (r = 0.552, p = 0.006, 95%CI [0.181, 0.785]). Body fat percentage was inversely associated with both Wingate peak power (r = −0.670, p < 0.001, 95%CI [−0.848, −0.356]) and VO₂max (r = −0.609, p = 0.002, 95%CI [−0.816, −0.263]). These findings suggest that explosive performance, anaerobic capacity, aerobic capacity, and body composition are interrelated in adolescent Muay Thai athletes. Importantly, these results are based on correlational analysis and do not imply causation. Accordingly, optimizing explosive performance and maintaining appropriate body composition may be associated with improved high-intensity performance within the demands of round-based Muay Thai competition.
