A decreased vital capacity is an indication of restrictive lung disease where the lungs cannot expand completely. How does an increased PaCO2, respiratory acidosis, alter the delivery of oxygen to the tissues? The increase in RV that occurs causes a corresponding decrease in ERV and IRV. Pulmonary diffusion and ventilation are respiratory adaptations to exercise, but again don't impact the volume of air you body can forcefully inhale and exhale.
