AB  - PURPOSE: To analyze the load-, force-, and power-velocity relationships and 
      determine the load that optimizes power output on the pull-up exercise. METHODS: 
      Eighty-two resistance-trained men (age 26.8 +/- 5.0 y; pull-up 1-repetition maximum 
      [1-RM; normalized per kg of body mass] 1.5 +/- 0.34) performed 2 repetitions with 4 
      incremental loads (range 70-100%1-RM) in the pull-up exercise while mean 
      propulsive velocity (MPV), force (MPF), and power (MPP) were measured using a 
      linear transducer. Relationships between variables were studied using first- and 
      second-order least-squares regression, and subjects were divided into 3 groups 
      depending on their 1-RM for comparison purposes. RESULTS: Almost perfect 
      individual load-velocity (R(2) = .975 +/- 0.02), force-velocity (R(2) = .954 +/- 
      0.04), and power-velocity (R(2) = .966 +/- 0.04) relationships, which allowed to 
      determine the velocity at each %1-RM, as well as the maximal theoretical force 
      (F0), velocity (V0), and power (Pmax) for each subject were observed. 
      Statistically significant differences between groups were observed for F0 (P < 
      .01) but not for MPV at each %1-RM, V0, and Pmax (P > .05). In addition, high 
      correlations between F0 and 1-RM (r = .811) and V0 and Pmax (r = .865) were 
      observed. Finally, the authors observed that the load that maximized MPP was 
      71.0% +/- 6.6%1-RM. CONCLUSIONS: The very high load-velocity, force-velocity, and 
      power-velocity relationships enables estimation of 1-RM by measuring movement 
      velocity, as well as determination of maximal force, velocity, and power 
      capabilities. This information could be of great interest to strength and 
      conditioning coaches who wish to monitor pull-up performance.
