AB  - PURPOSE: Power output is dependent on the load used during exercise such as 
      bench-press throw (BPT). Attentional focus (external [EXT] vs internal [INT]) 
      during exercise significantly modulates power performance. The purpose of the 
      present study was to examine the effects of load and attentional focus on 
      mechanical parameters during BPT. METHODS: In a crossover study, 31 
      resistance-trained men (mean age 23.5 [3.0] y) performed BPT at 30% (light), 50% 
      (moderate), and 70% (heavy) of 1-repetition maximum (1-RM) using an INT or EXT 
      focus of attention in randomized order. A linear encoder was used to identify 
      barbell vertical displacement, throw time, peak/average velocity, force, and 
      power during the concentric lifting phase. RESULTS: Statistical analysis revealed 
      significant load x focus interaction effects for velocity and vertical 
      displacement (P </= .045; 0.66 </= d </= 0.89). Post hoc analyses indicated 
      significantly larger velocities and displacements at 30% and 70% of 1-RM in favor 
      of EXT (P </= .038; 0.79 </= d </= 1.13) but similar values at 50% of 1-RM (P > .05). 
      Furthermore, significant main effects of load were found for throw time, force, 
      and power (P < .001; 4.20 </= d </= 14.0). While time and force gradually increased 
      with higher loads (P < .001; 1.45 </= d </= 14.0), power output was larger at 50% 
      compared with 30% and 70% 1-RM (P < .001; 3.09 </= d </= 7.07), irrespective of 
      attentional focus. CONCLUSIONS: The present findings indicated that practitioners 
      may use EXT over INT attentional focus to enhance velocity and vertical 
      displacement during BPT at light and heavy loads (ie, 30% and 70% 1-RM). At 
      moderate loads (ie, 50% 1-RM), mechanical bench-press parameters appear to be 
      less affected by attentional focus.
