The metabolic response to treadmill graded exercise: traditional vs. underwater in Comparative Exercise Physiology by P. Watson, C. Mendonca, R.A. Lehnhard, S. Tu1, S.A. Butterfield, T. Bouchard, K.H. McKeever
The purpose of this study was to determine the metabolic effect(s) of four graded exercise tests (GXT) performed on the underwater treadmill (UWT), and compare them to the results from performing the standard Bruce protocol on a traditional land treadmill (LT) for twelve male Division I college athletes. Results suggest that an UWT GXT protocol can be developed that would produce metabolic results similar to the Bruce through stage 5.
