Factors Affecting the Health-Related Quality of Life in Taiwanese Adolescent Baseball Players: A Prospective Longitudinal Study

Our study demonstrated significant differences in most FAST total and subscale scores among player positions. Pitchers and outfielders exhibited higher FAST scores than the other positions, indicating more physical disability and psychological impact. Furthermore, the severity of throwing arm injury history significantly influenced FAST scores, with more severe injuries correlating with poorer outcomes. However, training volume did not significantly impact FAST scores. These data may help in future studies integrating patient-reported outcomes and HRQOL to evaluate athlete's' well-being beyond just physical parameters.
