Kinetics of Peripheral Muscles Oxygenation Throughout an exercise Take to We also examined the relationships between V?Odos and the slopes of HR/V?O2, SpO2/V?O2, StO2/V?O2, and MOER/V?O2. The influence of V?O2 on the HR/V?O2 slope is partially expressed in the cardiac response, the SpO2/V?O2 slope in the respiratory response, and the StO2/V?O2 and MOER/V?O2 slopes in the muscle response. peak V?O2 did not correlate with any of the slopes (Fig. 3). In subject step one the HR/V?O2, SpO2/V?O2, and StO2/V?O2 slopes…
