AB  - Ben-Zeev, T, Sadres, E, and Hoffman, JR. Comparison of force measures between 
      start position, transition phase, and midthigh pull with weightlifting 
      performance during Israel National Competition. J Strength Cond Res 37(11): 
      2200-2205, 2023-This study compared the relationship between peak force (PKF) and 
      rate of force development (RFD) at isometric start position pull (ISPP), 
      isometric transition position pull (ITPP), and isometric midthigh pull (IMTP) 
      with the snatch (SN), clean and jerk (C&J), and total score (TOT) in 30 national 
      and international Israeli weightlifters (18 men and 12 women). All measures were 
      collected either 1 week before or 1 week after the Israel weightlifting 
      championship. A significant correlation was observed between peak force at all 
      pull positions and performance in the SN, C&J, and TOT for men, women, and both 
      sexes combined ( p < 0.001). The correlations were all very strong (e.g., r 
      values all above 0.90) for both ISPP and ITPP, and all weightlifting performance 
      variables, whereas the correlation between IMTP and weightlifting performance 
      ranged from moderate ( r = 0.69) to strong ( r = 0.89). In addition, significant 
      differences were observed between the correlation coefficient value in ISPP and 
      ITPP with the TOT score compared with the correlations observed in IMTP ( z = 
      0.7, p = 0.046, and z = 1.7, p = 0.049, respectively). Significant differences 
      were also observed in the women group for ISPP for the SN and TOT score compared 
      with the correlation in IMTP ( z = 1.72, p = 0.043, and z = 1.75, p = 0.040, 
      respectively). Rate of force development at 250 milliseconds significantly ( p 
      values <0.05) correlated with the SN, C&J, and TOT in women ( r 's = 0.65, 0.68, 
      and 0.67, respectively), and when both sexes were combined ( r 's = 0.59, 0.61, 
      and 0.60, respectively), but not for the men. Results of this investigation 
      indicated the importance of isometric force capabilities at ISPP and ITPP for 
      weightlifting performance.
