A Critical Review of the History of Low- to Moderate-Intensity Steady-State VO2 Kinetics

摘要: Research into the rate of whole-body oxygen consumption (VO2) kinetics during exercise increments to low- moderate-intensity steady-state was originally based on theory linear first-order VO2 kinetics, implying that response is a mono-exponential same time constant (tau, τ) across all intensities. Despite acceptance this for more than 30 years, early research from 1980s documented an increasing τ with intensity, and recent has confirmed such results. Today, evidence led retraction kinetics. This history, revealing premature theory, subsequent scientific investigation using improved design, instrumentation data processing, important implications fragility theories need continual testing in search facts not prematurely accepted constructs. review provides historical critical reappraisal presents show changes data-processing ‘standards’ discipline improve measurement instantaneous steady state. For example, date, no study quantified statistically analysed Furthermore, instability different increments, increment baseline demand, prevents being valid measure conditions. The concept quantifying total non-linear response, when other field pursues methodology, also raises concern methods models used interpret
