Study Summary
Studies in mice demonstrated that dietary phosphate (Pi) loading that mimic the level of US adult consumption leads to reduced spontaneous locomotor activity, exercise capacity, and reduced resting metabolic rate when in normal mice by impairing skeletal muscle mitochondrial function and fat oxidation. However, relevance of this findings in humans remains unknown.
Primary Outcome
VO2 (ml of oxygen consumed /min) will be measured using a metabolic cart (Medgraphics) during exercise in a stationary bicycle. Standard breath-by-breath respiratory gases (VO2) will be measured at rest and after 3 minutes of steady state exercise at both 20 and 40 Watts using a cycle ergometer (Lode). Then, the partcipants will be asked to perform exercise to maximal level to obtain peak VO2.
