Key result
Submaximum cycle ergometry yielded reliable steady-rate ventilation, oxygen uptake, and heart rate responses (r=0.69 to 0.97), but lower reliability for blood pressure (r=0.27 to 0.80).

Submaximal cycle ergometry yields reliable cardiorespiratory but not blood pressure responses; leaves open protocol standardization for clinical testing.
What is the reliability and within-subject variability of physiological parameters during submaximum cycle ergometry?
During submaximum cycle ergometry, steady-rate ventilation, oxygen uptake, and heart rate are reliable measures, whereas blood pressure shows low reliability.
Becque et al. (1993) studied this question. Submaximum cycle ergometry was evaluated on Reliability and within subject variability of steady-rate ventilation (VE), oxygen uptake (VO2), heart rate, and blood pressure. Submaximum cycle ergometry yielded reliable steady-rate ventilation, oxygen uptake, and heart rate responses (r=0.69 to 0.97), but lower reliability for blood pressure (r=0.27 to 0.80).
