AB  - The purpose of this study was to explore the relationships between isometric 
      mid-thigh pull (IMTP) force-time characteristics (peak force and time-specific 
      force vales (100(-)250 ms)) and dynamic performance and compare dynamic performance 
      between stronger and weaker athletes. Forty-three athletes from different sports 
      (rowing, soccer, bicycle motocross, and hockey) performed three trials of the 
      squat jump (SJ), countermovement jump (CMJ), and IMTP, and performed a one 
      repetition maximum power clean (PC). Reactive strength index modified (RSImod) 
      was also calculated from the CMJ. Statistically significant large correlations 
      between IMTP force-time characteristics and PC (rho = 0.569(-)0.674, p < 0.001), and 
      moderate correlations between IMTP force-time characteristics (excluding force at 
      100 ms) and RSImod (rho = 0.389(-)0.449, p = 0.013(-)0.050) were observed. Only force 
      at 250 ms demonstrated a statistically significant moderate correlation with CMJ 
      height (rho = 0.346, p = 0.016) and no statistically significant associations were 
      observed between IMTP force-time characteristics and SJ height. Stronger athletes 
      (top 10) demonstrated statistically significantly greater CMJ heights, RSImods, 
      and PCs (p </= 0.004, g = 1.32(-)1.89) compared to weaker (bottom 10) athletes, but 
      no differences in SJ height were observed (p = 0.871, g = 0.06). These findings 
      highlight that the ability to apply rapidly high levels of force in short time 
      intervals is integral for PC, CMJ height, and reactive strength.
