Baseline work rate may alter critical power estimates in supine exercise; leaves open effects on testing protocols and oxygen uptake determinants.

Absolute Event Rate: 132% vs 146%
p-value: p=0.023
The study demonstrates that the phase II time constant of pulmonary oxygen uptake kinetics is an independent determinant of critical power even when oxygen availability is limiting during supine exercise.
Goulding et al. (2018) studied this question. Supine cycling initiated from a moderate-intensity baseline work rate (M→S) vs. Supine cycling initiated from an unloaded baseline (U→S) was evaluated on Critical power (CP) (p=0.023). Initiating supine cycling from a moderate-intensity baseline significantly decreased critical power (132 ± 33 W vs. 146 ± 39 W, P=0.023) compared to an unloaded baseline.
