Nonexercise Equations for Determining Change in Cardiorespiratory Fitness

Purpose This study aimed to determine whether change in estimated cardiorespiratory fitness (eCRF) is associated with change in measured cardiorespiratory fitness (mCRF) independent of exercise amount and intensity over 24 wk. Methods Participants were 163 sedentary adults with abdominal obesity (mean ± SD waist circumference, 109.9 ± 11.5 cm) randomly assigned to (i) no-exercise control ( n = 42); (ii) low-amount, low-intensity exercise (LALI;...
