Recumbent stepper submaximal exercise test to predict peak oxygen uptake.

Purpose: The purpose of this study was to examine the ability of the YMCA submaximal exercise test protocol using a total body recumbent stepper to predict V˙O(2peak).

Methods: Of 112 individuals initially screened, 110 individuals with low to moderate cardiovascular disease risk met the inclusion criteria for participation in the study. The maximal exercise test used a motorized treadmill and the Bruce or modified Bruce protocol.
