Athletes must maintain their physical and mental condition to sustain performance and prevent mental health decline. Given the variability in individual responses to training, tailored conditioning support is crucial. Additionally, multiple factors interact during athlete conditioning, necessitating an analytical approach that effectively captures these complex dynamic relationships. However, previous research and practice have primarily focused on the variability of individual variables and unilateral relationships between group-averaged independent and dependent variables, paying limited attention to interactions among variables within individuals. The psychological network approach, which models the interactions among mental health symptoms to optimize individualized treatments, has recently gained prominence in clinical psychology. Given the significant individual differences in physical and psychological responses and interactions among conditioning variables, this approach may also offer a valuable framework for athlete conditioning. Therefore, this study outlines the psychological network approach and then explores its potential for individualized conditioning strategies. Additionally, building on existing research and practices related to athlete conditioning supports the psychological network approach. We also consider future challenges and research directions for practical applications. In conclusion, despite some challenges, the psychological network approach may provide individualized strategies to optimize athlete performance and mental health.
