A Simple Step Test to Estimate Cardio-Respiratory Fitness Levels of Rheumatoid Arthritis Patients in a Clinical Setting

Table 2

Physiological variables from the maximal cycling ergometry test in 22 patients (17 females and 2 males).

	Females	Males	Total group
HRpeak	158±13	159±22	158±15
Age predicted max (%)	95±6	93±8	95±7
V̇O2peak (mL·kg^−1·min^−1)	19.2±4.1	22.3±4.0	19.9±4.2
RERpeak (V̇O2/V̇CO2)	1.18±0.12	1.14±0.04	1.18±0.11
RPE (15 point scale)	19±2	18±2	19±2

Values are mean ± SD. RER: respiratory exchange ratio; RPE: ratings of perceived exertion; V̇O₂: oxygen consumption; V̇CO₂: carbon dioxide production.
