<![CDATA[Long jump is a technically demanding track-and-field event in which performance depends on the interaction of multiple biomotor components. While previous studies have examined the individual effects of explosive power, balance, and flexibility on athletic performance, a comprehensive synthesis of their combined contribution to long jump achievement remains limited. This narrative review critically examines theoretical and empirical evidence from Scopus-indexed literature to evaluate the independent and integrated roles of lower-limb explosive power, postural balance, and musculoskeletal flexibility in long jump performance. The reviewed evidence consistently identifies lower-limb explosive power as the strongest predictor of jump distance, explaining up to 43% of performance variance among athletes. Balance contributes approximately 28%, while flexibility accounts for about 12% of the variance. Collectively, these three biomotor qualities explain up to 77% of long jump performance variability. Mechanistically, explosive power facilitates the generation of optimal horizontal and vertical impulses during take-off, balance supports approach-run stability and landing control, and flexibility enhances joint range of motion, enabling efficient force production and movement execution. These findings highlight the multidimensional nature of long jump performance and emphasize the importance of integrated training programmes that simultaneously develop explosive power, balance, and flexibility. Future research should further investigate the interaction of these biomotor components across different athlete populations and performance levels.]]>
