The effect of body position on cardiovascular, skeletal muscle and ventilatory responses to submaximal cycling.

ABSTRACT: The completion of exercise in different body positions can impact the function of various components of the oxygen delivery pathway; however, the effect of the haemodynamic conditions induced by a semi-upright body position on the integrative physiological response to exercise is poorly understood. The purpose of this study was to explore the effect of a semi-upright body position on cardiac output (CO), vastus lateralis oxygen saturation ( S m O 2 ${{S}_{{\mathrm{m}}{{{\mathrm{O}}}_2}}}$ ), oxygen consumption ( V ̇ O 2 ${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$ ) and ratings of perceived exertion (Borg RPE) during submaximal cycling. Twenty healthy individuals (22 ± 3 years, 50% female) each completed alternating 5-min bouts of submaximal upright and semi-upright (40° incline) cycling at
