Comparison of sitting, and sitting to standing cycle ergometry versus treadmill, on cardiorespiratory values in adult males and females

The primary purpose of this study was to determine if standing on a cycle ergometer (CE) towards the conclusion of a graded exercise testing (GXT) would increase the CE cardiorespiratory values equal to the same treadmill (TM) values in recreationally-aerobically-trained subjects (11 males, 11 femal...

Description
Summary:The primary purpose of this study was to determine if standing on a cycle ergometer (CE) towards the conclusion of a graded exercise testing (GXT) would increase the CE cardiorespiratory values equal to the same treadmill (TM) values in recreationally-aerobically-trained subjects (11 males, 11 females) participated in this study. The subjects completed three GXT trials, one by TM, and two by CE. In one CE trial, the subjects remained seated throughout the GXT (Sit CE). In the other CE trial, initially-seated subjects stood up and pedaled after their RER was 1.0 (Stand CE). Sit CE-GXT and Stand CEGXT cardiorespiratory values were statistically equivalent to the TM-GXT values in recreationally-aerobically-trained male and female subjects. On some cardiorespiratory variables, gender differences were likely caused by body composition differences between males and females. The encouraging findings of the present study suggest that, with further refinement of the "Stand CE" technique, it might become the method of choice in GXT in some populations.
