In volleyball, performance components such as spike speed, serve speed, and grip strength are critical for athletic success. This study investigated the effects of an eight-week TRX training program on these variables in female volleyball players aged 12 to 14. Participants were randomly assigned to a TRX training group (TRX-G, n=16) or a serve and spike training group (SS-G, n=16). Pre- and post-tests measured spike speed, serve speed, and grip strength. Repeated measures ANOVA and correlation analyses were used to analyze the data. The TRX-G showed significant improvements in spike speed (p<0.01), serve speed (p<0.001), and grip strength (p<0.001). The SS-G improved only in serve speed (p<0.05). Between-group comparisons revealed that TRX training was sig-nificantly more effective across all performance measures (p<0.001). A significant positive correlation was found between spike and serve speed (r=0.62; p<0.01), while grip strength showed no significant relationship with speed variables. These findings suggest that TRX training effectively enhances key volleyball performance skills and may be integrated into training routines to support athletic development in youth volleyball players.
