Alterations And Specifications Of Excess Post-Exercise Oxygen Consumption: A Review, Genevieve Kocoloski, Anne R. Crecelius

Health and Sport Science Faculty Publications

This review describes oxygen consumption, both in terms of a goal of weight management and aerobic training. It introduces excess postexercise oxygen consumption (EPOC) and the benefits that can come from it. EPOC can aid in weight management as a means to continue to expend energy even after exercise has ceased. This review also discusses the many determinants of EPOC and analyzes the effects of various conditions on the elevated consumption. Such conditions include duration and intensity of exercise, training status, and supplementation. Later discussed are the possible underlying mechanisms and how they are responsible for EPOC. Although they have …

Unaccustomed Exercise Causes Rhabdomyolysis, Yuri Feito

Faculty Articles

Cross Fit TM is a relatively new strength and conditioning program defined as “constantly varied, functional movements, performed at a high intensity”. The goal of the program is to increase “work capacity across broad time and modal domains” [1]. Even though this training modality has been criticized by the main stream media for “high risk of injury” most of these claims have been anecdotal, as recent evidence suggest this training modality is not any more “dangerous” than other exercise programs [2]. One of the biggest criticisms of this training modality has been its association with Rhabdomyolysis, a condition that results …
