Abstract: Speed climbing requires high levels of explosive power, maximal strength, and psychological readiness. However, limited empirical evidence has examined how physical training methods interact with psychological attributes, particularly self-efficacy, in influencing performance. This study aimed to investigate the effects of circuit and conventional plyometric training on speed climbing performance, differences in performance between athletes with high and low self-efficacy, and the interaction between training method and self-efficacy level. A quasi-experimental study employing a 2 × 2 factorial design was conducted among 38 eligible male Indonesian elite athletes aged 21–27 years. Based on the 27% extreme group technique for self-efficacy classification, 20 athletes representing the highest and lowest self-efficacy levels were included in the final analysis (n = 20). Participants were assigned to four groups based on training method and self-efficacy level, assessed using the General Self-Efficacy Scale. Climbing speed performance was measured before and after an eight-week intervention, conducted three sessions per week, using Motion Climb sensor technology. Data were analyzed using Two-Way ANOVA at a significance level of α = 0.05. The results indicated that circuit plyometric training produced significantly greater improvements in climbing speed than conventional training (F = 20.801, p < .001). Athletes with high self-efficacy demonstrated significantly superior performance gains compared with those with low self-efficacy (F = 16.712, p = .001). A significant interaction effect was observed (F = 5.284, p = .035), with the circuit training and high self-efficacy combination yielding the greatest improvement.
