Estimation of Cardiorespiratory Fitness Without Exercise Testing: Cross-Validation in Midlife and Older Women.

ABSTRACT:

Background

Cardiorespiratory fitness (CRF) is associated with important health risk outcomes, including the development of Type 2 diabetes and cardiovascular disease. Measures of maximal or peak oxygen consumption (VO₂) are the typical criterion methods for determining CRF; however, in clinical settings, these measures are impractical.

Methods

We validated a clinically derived estimate of CRF against predicted maximal VO₂ in a sample of healthy, midlife and older adult women (n = 188). Women completed a clinic evaluation (including treadmill testing), daily diaries about their physical activity, and additional clinical scales. Two models were tested. The first model calculated estimated cardiorespiratory fitness (eCRF) using assigned weights and
