Changes in cardiac function at rest, exercise time, and recovery time for all the conditions. a change in HR (bpm). b change in SV (mL). c change in EDV (mL). d change in ESV (mL). e change in EF (%). f change in CO (L/min). The bars indicate the mean ± S.D. A p < .05 vs. 20.9 % O2, B p < .05 vs. 16.5 % O2, C p < .05 vs. 14.5 % O2, D p < .05 vs. 12.8 % O2
