The purpose of this study was to investigate acute blood lactate concentration, heart rate, blood pressure, and rating of perceived exertion following two different types of exercise: a high intensity power training exercise test and a graded treadmill exercise test. The hypothesis was that the HIPT exercise test would yield higher levels of blood lactate, heart rate, blood pressure, and RPE, immediately post exercise when compared to a graded treadmill exercise test. Ten college-aged participants with a body mass index /m2, blood pressure \u3c140/90 mmHg, no overt cardiovascular disease, no cardiovascular medications, and no use of tobacco products were included in the study. All participants had a general fitness and training level that allowed them to perform the exercise bouts without any hesitation. Subjects participated in two exercise sessions on separate occasions. A graded treadmill exercise test occurred with the subjects walking on the treadmill until the self-stated desire to stop or until five stages of increased speed and intensity had occurred. In the second meeting, subjects completed a prescribed high-intensity power training exercise test. Heart rate (HR), rating of perceived exertion (RPE), blood pressure (BP), and blood lactate concentration were all obtained before and immediately following each training session, as well as immediately following each stage of the graded treadmill exercise test. Oxygen uptake was obtained during the graded treadmill exercise test. After both tests were conducted, the high intensity power training exercise test showed a higher percentage of blood lactate concentration at its conclusion when compared to the graded treadmill exercise test with lower final average values BP, HR and RPE. In conclusion HIPT exercise yields higher blood lactate concentrations compared to graded treadmill exercise with a lower blood pressure, heart rate, and perceived exertion
