Lack of time is a common barrier to exercise participation in the general population. Lack of exercise may lead to a disruption in the energy balance equation. The purpose of the study was to determine caloric expenditure differences post-isocaloric bouts of steady state exercise and high intensity interval training. Thirteen recreationally active individuals (9 female, 4 male; 21.3±1.4yrs) participated in this study which included performing trials of steady state exercise and high intensity interval training. Trials were matched for volume of exercise based on energy used and lasted 60 minutes. The total caloric expenditure was used for data analysis. The caloric expenditure for steady state exercise trials were 261.5±74.4kcals and 284.8±83.9kcals for high intensity interval training and determined to have significant difference. In conclusion, high intensity interval training elicits statistically greater energy expenditure versus steady state exercise.
