Improved VO2max and Cardiac Output in Response to Training Clinical Trial
Official title:
Effect of Ethnicity on Changes in VO2max and Cardiac Output in Response to Short-Term High Intensity Interval Training
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.
Prior to the session, women completed a 4-minute warmup at 10 % PPO. Each subject completed 9 sessions of HIIT over a 3-week period which consisted of eight to ten 1-minute bouts of cycling at 85% PPO with 75-second recovery between bouts at 10 % PPO. This protocol is well-tolerated in inactive individuals. Continuously during each session, heart rate was monitored using telemetry. On days 1, 3, 6, and 9 of training, the physical activity enjoyment scale (PACES) was completed. VO2max and cardiac output max were assessed prior to training, as well as post. ;
