Cardiorespiratory factors related to the increase in oxygen consumption during exercise in individuals with stroke

Background Understanding the cardiorespiratory factors related to the increase in oxygen consumption (V˙O2) during exercise is essential for improving cardiorespiratory fitness in individuals with stroke. However, cardiorespiratory factors related to the increase in V˙O2 during exercise in these individuals have not been examined using multivariate analysis. This study aimed to identify cardiorespiratory factors related to the increase in V˙O2 during a graded exercise in terms of respiratory function, cardiac function, and the ability of skeletal muscles to extract oxygen.
