TI  - Relationships of isometric mid-thigh pull variables to weightlifting performance.
PG  - 573-81
AB  - AIM: The purpose of this study was to evaluate the relationship between 
      weightlifting performance (snatch, clean and jerk, and total) and variables 
      obtained from the isometric mid-thigh pull (IMTP). METHODS: Twelve weightlifters, 
      ranging from novice to advanced, performed the IMTP 10 days after a competition. 
      Correlations were used to evaluate relationships between variables of the IMTP 
      and absolute and scaled competition results. RESULTS: Unscaled competition 
      results correlated strongly with IRFD (0-200ms: r=0.567-0.645, 0-250ms: 
      r=0.722-0.781) while results correlated weakly with Peak IRFD (5ms window, 
      r=0.360-0.426). Absolute peak force values correlated very strongly with absolute 
      values for the competition performance (r=0.830-0.838). Force at 100ms, 150ms, 
      200ms and 250ms also correlated strongly with competition results (r=0.643-0.647, 
      r=0.605-0.636, r=0.714-0.732, r=0.801-0.804). Similar findings were noted for 
      allometrically scaled values. CONCLUSION: Measures of average IRFD probably 
      represent a more relevant variable to dynamic performance than does Peak IRFD 
      (5ms). Maximum isometric strength also is likely to have a strong role in 
      weightlifting performance.
