Methods: VO2 and SmO2 were measured simultaneously during a gradually ascending running protocol and a Bruce protocol. VO2 was measured by breath-by-breath spiroergometer gas analysis system (ZAN®, Germany), and SmO2 was measured from both gastrocnemius muscles using a wireless near-infrared spectroscopy device (BSXinsight®, USA). The correlation between VO2 and SmO2 data was determined by Pearson correlation coefficients over the test stage mean values. The change of VO2 and SmO2 within each stage was determined by first-degree polynomials.
Results: Peak VO2 in the Bruce protocol (4640 ml/min) was higher than peak VO2 in the running protocol (4390 ml/min), but no difference was observed in end-test SmO2 decreases. There were highly significant negative correlations between VO2 values and SmO2 values (r=-0.960-0.990, p<0.001). SmO2 values measured in the right and left gastrocnemius muscle decreased similarly in both protocols (r=0.993, r=0.987, p<0.001).
Conclusion: Central and peripheral physiological processes of oxygen consumption are not always congruent, and the test protocol exert an influence due to the complex interplay of physiological and biomechanical factors.}, number={2}, publisher={İbrahim ERDEMİR}
