AB  - PURPOSE: To determine whether athletes from different sport disciplines present 
      similar mean propulsive velocity (MPV) in the half-squat (HS) during submaximal 
      and maximal tests, enabling prediction of 1-repetition maximum (1-RM) from MPV at 
      any given submaximal load. METHODS: Sixty-four male athletes, comprising American 
      football, rugby, and soccer players; sprinters and jumpers; and combat-sport 
      strikers attended 2 testing sessions separated by 2-4 wk. On the first visit, a 
      standardized 1-RM test was performed. On the second, athletes performed HSs on 
      Smith-machine equipment, using relative percentages of 1-RM to determine the 
      respective MPV of submaximal and maximal loads. Linear regression established the 
      relationship between MPV and percentage of 1-RM. RESULTS: A very strong linear 
      relationship (R2  approximately  .96) was observed between the MPV and the percentages of HS 
      1-RM, resulting in the following equation: %HS 1-RM = -105.05 x MPV + 131.75. The 
      MPV at HS 1-RM was ~0.3 m/s. CONCLUSION: This equation can be used to predict HS 
      1-RM on a Smith machine with a high degree of accuracy.
