The purpose of this study was to examine how IMW affects the sensory and affective components of dyspnea, exercise performance, and NIRS-derived metaboreflex effects during a cycling time to exhaustion test. Additionally, to augment the ventilatory response for better elucidation of the cardiorespiratory effects of IMW, we added hypoxia as an intervention. Using both normoxic and hypoxic conditions, our hypotheses were: 1) both sensory and affective components of dyspnea would be attenuated following IMW in each condition, 2) the extent of skeletal muscle deoxygenation (i.e., a NIRS-derived surrogate for the metaboreflex) in the leg would be reduced after IMW in each condition, and 3) participants’ time to exhaustion would be prolonged following IMW in each condition.
