The purpose of this study was to determine the effects of heavy-resistance strength training on measures of bench press power (BPP) using absolute loads and seated shot: put (SSP) performance. Twenty-four college men were measured for 1-RM bench press, BPP, and SSP before and after weight training twice weekly for 12 weeks. BPP was measured with free weights using a digital timing system and randomly assigned loads equivalent to 30 %, 40 %, 50 %, 60 %, 70 % and 80 % of the T-RM. Post-training tests used the same absolute loads as during the pre-training test to assess BPP. Following training BPP increased significantly at each load, shifting the power curve upward by an average of 13.6 %. The 1-RM bench press increased significantly by 9.1 %, but the SSP increased nonsignifi-cantly by only 1.8 %. Peak power was produced at approximately 40 - 50 % of the 1-RM before and after training. Changes in SSP distance were nonsignificantly correlated (r = 0.27 - 0.20) with the increases in BPP. Resistance training shifts the power curve in a positive direction when the measurements are determined with absolute loads, but the increased power may not be transferred to an absolute performance task like the SSP.
