Purpose: To determine whether a moderate 1-km treadmill walking test (1KTWT) could be used to predict peak oxygen uptake ((Equation is included in full-text article.)O2peak) in patients with cardiovascular disease. Methods: One hundred seventy-eight male patients, aged 38 to 83 years, completed a (Equation is included in full-text article.)O2peak treadmill test and a 1KTWT using a self-regulated intensity of 11 to 13 of 20 on the Borg scale. Multivariable regression analysis was used to develop equations for predicting (Equation is included in full-text article.)O2peak in a development group (n = 110), both for subjects prescribed and not prescribed a β-blocking agent (BB/NBB, 66/44). These equations were then applied to a cross-validation and reproducibility group (n = 68, BB/NBB, 37/31), who completed the protocol twice within 2 weeks. Results: Analysis from 1KTWT in the development group showed that age, body mass index, walking speed, and heart rate were the most potent predictors of (Equation is included in full-text article.)O2peak. Measured and predicted (Equation is included in full-text article.)O2peak were not significantly different, and were strongly associated among both the NBB (r = 0.81, P < .0001) and BB (r = 0.69, P < .0001) groups, with a mean residual of approximately 1.0 mL•kg-•min-. When applied to the cross-validation and reproducibility group, the equations similarly yielded strong associations (r = 0.64, P < 0.001 and r = 0.71, P < 0.001 for the NBB and BB groups, respectively), with no significantly differences between measured and predicted (Equation is included in full-text article.)O2peak. Mean test-retest differences for measured and predicted (Equation is included in full-text article.)O2peak were between 0.1 and -0.5 mL•kg-•min-. Conclusions: Equations developed from the 1KTWT accurately predicted (Equation is included in full-text article.)O2peak in patients with cardiovascular disease. The model may represent a valid, low cost, and simple tool for indirect estimations ... |
