Assessment of V̇o2peak and Exercise Capacity After Stroke: A Validity Study of the Human Activity Profile Questionnaire

•The Human Activity Profile (HAP) is a clinically applicable way to provide VO2peak.•The HAP questionnaire is used to provide a valid value of VO2peak (in mL/kg−1/min−1).•The HAP demonstrated adequate validity to assess exercise capacity.•The HAP can be used to assess cardiorespiratory fitness when cardiopulmonary exercise testing cannot be performed. To investigate the concurrent validity of the Human Activity Profile (HAP) in individuals after stroke to provide the peak oxygen uptake (V̇o2peak) and the construct validity of the HAP to assess exercise capacity, and to provide equations based on the HAP outcomes to estimate the distance covered in the Incremental Shuttle Walking Test (ISWT). Cross-sectional study. University laboratory. Individuals (N=57) aged 54±11 years who have experienced stroke. Not applicable. Agreement between the V̇o2peak provided by the HAP (lifestyle energy consumption [LEC] outcome, in mL/kg−1/min−1) and the criterion standard measure of the V̇o2peak (mL/kg−1/min−1), obtained through the symptom-limited Cardiopulmonary Exercise Test (CPET). Correlation between the HAP outcomes (LEC, maximum activity score [MAS], and adjusted activity score [AAS]) and the construct measure: the distance covered (in meters) in the ISWT. An equation to estimate the distance covered in the ISWT was determined. High magnitude agreement was found between the V̇o2peak, in mL/kg−1/min−1, obtained by the symptom-limited CPET and the value of V̇o2peak, in mL/kg−1/min−1, provided by the HAP (LEC) (intraclass correlation coefficient, 0.75; P
