The Impact of Cycling Cadence on Respiratory and Hemodynamic Responses to Exercise

Purpose The physiological consequences of freely chosen cadence during cycling remains poorly understood. We sought to determine the effect of cadence on the respiratory and hemodynamic response to cycling exercise. Methods Eleven cyclists (10 males, …

The effect of severe and moderate hypoxia on exercise at a fixed level of perceived exertion

Purpose: The purpose of this study was to determine the primary cues regulating perceived effort and exercise performance using a fixed-RPE protocol in severe and moderate hypoxia. Methods: Eight male participants (26 ± 6 years, 76.3 ± 8.6 kg, 178.5 …

Aerobic interval training improves oxygen uptake efficiency by enhancing cerebral and muscular hemodynamics in patients with heart failure

Background: Abnormal ventilatory/hemodynamic responses to exercise contribute to functional impairment in patients with heart failure (HF). This study investigates how interval and continuous exercise regimens influence functional capacity by …

Suppression of cerebral hemodynamics is associated with reduced functional capacity in patients with heart failure

This investigation elucidated the underlying mechanisms of functional impairments in patients with heart failure (HF) by simultaneously comparing cardiaccerebral- muscle hemodynamic and ventilatory responses to exercise among HF patients with various …
