Isometric single-joint rate of force development shows trivial to small associations with jumping rate of force development, jump height, and propulsive duration

The association between single-joint isometric rate of force development (RFDISO) and jumping outcomes remain largely unexplored. Further, the importance RFD assessed during for jump height duration (i.e. time from onset to take-off) remains ambiguous. We therefore investigated these associations in a large heterogenous sample. Cross-sectional study. Three-hundred-twenty-six male female basketball tennis players, physical education students performed bilateral squat (SJ) both unilateral countermovement jumps (CMJ). Single-joint RFDISO was hip extensors, knee extensors ankle relevant were computed. Knee showed small positive correlations with RFDSJ RFDCMJ. Ankle moderate correlation CMJ SJ height, but trivial duration. Stepwise linear regression that combination different muscle groups explained variance (∼23–28%), (∼2–3%), (∼19–28%). negative duration, respectively while CMJ. imply improving could benefit performance. However, mostly suggests assessments provide only limited information regarding sports-related movements.
