The purpose of this study was to compare the effects of different exercise types including isokinetic, isometric, and istonic exercise of same exercise intensity on cardiopulmonary function and blood lactate level. The subjects of this study included 17 males college students. Each subjects after pretraining measurement performed isokinetic, isometric and isotonic exercise of 1 week interval using Cybex 6000 System. KBI-C and YSI 1500 were used to measure changes in cardiopulmonary function and blood lactate level respectively. First, comparing changes in RPP relative to exercise type, isokinetic group showed significant difference between before exercise ($7.08{pm}1.12mg/kg/min$) and post exercise ($18.98{pm}1.75mg/kg/min$). Isometric group showed that significant difference between before exercise($7.89{pm}0.98mg/kg/min$) and post exercise($20.22{pm}2.41mg/kg/min$). Isotonic group showed significant difference between before exercise ($8.14{pm}0.11mg/kg/min$) and post exercise ($19.84{pm}2.30;mg/kg/min$). Second, comparing changes in blood lactate level relative to exercise type, isokineic group showed significant difference between before exercise ($2.99{pm}0.65mmol$) and post exercise ($6.55{pm}6.55mmol$). Isometric group showed significant difference between before exercise($1.71{pm}5.48mmol$) and post exercise ($5.48{pm}1.97mmol$). Isotonic group showed significant difference between before exercise($1.16{pm}0.48mmol$) and post exercise($5.21{pm}1.28mmol$). The results of this study indicate significant differences RPP in isometric exercise and significant differences blood lactate in isotonic exercise.
