Abstract This study, in which rats were exposed on 12 successive days to hypoxia in combination with exercise on a treadmill, showed that a reduction in partial oxygen pressure leads to a decrease in the magnitude of the structural component of vascular resistance rather than to improvement in the system of oxygen utilization, and that such combined exposure may cause alterations in protein synthesis and result in early stimulation of capillary growth in muscles, as well as elicit differential changes of enzyme activity in different types of muscle fibers.
