The heart rate, energy requirement, mechanical work, and mechanical efficiency were measured on the bench press and 2-arm curl exercises in 4 male subjects (2 : trained, 2 : untrained). Four kind of the exercise intensity, such as 0,60,80,and 100%, which were obtained from the ten repetition maximum (10RM), were used on this study. The exercise was done repeatedly 10 times over for about 30 seconds. The results obtained are as follows : 1) Lifting weight was ranged from 20kg to 110kg on the bench press and from 10kg to 32.5kg on the 2-arm curl. 2) There has been an almost exponential increase on the oxygen requirement with increment of the exercise load. The equations are y=123.08×1.0290^x on the bench press and y=156.00×1.0532^x on the 2-arm curl in the relationship between oxygen requirement and lifting weight, and y=57.78×1.0135^x and y=152.04×1.0105^x in oxygen requirement and mechanical work. 3) The oxygen requirements are 0.2-2.1l/min on the bench press and 0.2-0.9l/min on the 2-arm curl. 4) In the bench press the mechanical efficiency was calculated from 6% to 30%, and from 7% to 20% in the 2-arm curl. The tendency of the mechanical efficiency on the two different exercise was discussed.
