Association of Step Count with Cardiorespiratory Fitness: Results from the Virtual 2-Minute Step Test.

ABSTRACT:

Objective

To test the hypothesis that step count based on a virtual 2-minute step test (2MST) predicts cardiorespiratory fitness (CRF).

Design

Cross-sectional study.

Setting

Veteran Affairs Medical Centers participating in a randomized trial of functional exercise training delivered by videoconferencing.

Participants

People with human immunodeficiency virus (HIV) (PWH) who were aged ≥50 years and clinically stable on antiretroviral therapy were eligible for the trial. Consecutive male participants who were enrolled prior to November 9, 2023 and completed a baseline 2MST and cardiopulmonary exercise test (CPET) were included in the cross-sectional study (N=74).

Intervention

None.

Main outcome measures

Step count was measured by a 2MST performed by
