Study Summary
The purpose of this study was to determine if ethnicity alters training responsiveness to a low dose of high intensity interval training in inactive women.
Primary Outcome
Each participant performed VO2max testing on an electronically-braked cycle ergometer using a ramp protocol. During exercise, subjects expired through a plastic mouthpiece and low resistance valve into tubing connected to a mixing chamber. Measures of ventilation and expired fractions of oxygen and carbon dioxide were obtained throughout exercise by a metabolic cart. Gas exchange data including VO2, VCO2, and ventilation were time-averaged every 15 seconds. The test was terminated when the subje
Interventions
