The aim of this study was to determine the relationship between snatch and clean performance with force-time characteristics obtained from isometric first (IFP) and isometric mid-thigh pull (IMTP) over several mesocycles. Ten male and female weightlifters (age: 27.4 ± 1.9 years, body mass: 69.8 ± 113.2 kg, height: 1.67 ± 0.08 m) from the national training squad performed the IFP, IMTP, and 85% of season`s best for snatch and clean on three separate occasions each separated by eight weeks. Near perfect correlations were observed between IFP and IMTP peak force (PF) with snatch and clean peak power (PP) and mean power (MP) on week 0, 8, and 16 (r = 0.954 - 0.991, p < 0.001). Very large - near perfect correlations were observed between IFP force at 200 ms (Force200) and IFP rate of force development at 200 and 250 ms (RFD0-200 and RFD0-250, respectively) with snatch and clean PP and MP at week 0 (r = 0.753 - 0.847, p = 0.008 - 0.048). Very large - near perfect correlations were observed between IFP Force50 and Force200 with snatch and clean PP and MP at week 8 and 16 (r = 0.777 - 0.865, p = 0.004 - 0.032). Very large correlations were also observed between IFP RFD0-200 and RFD0-250 with clean PP and MP at week 16 (r = 0.752 - 0.778, p = 0.032 - 0.048). The results indicate the importance of maximum force capabilities at both first and second pull positions, and early force development and RFD at first pull position for weightlifting performance.
