The aim of this study was to analyze subjective, physical, and
physiologic responses to a standardized incremental 30-min two-step stool test to
create an individualized 45-min maximally intensive two-step stool endurance
exercise regimen for home training. DESIGN: This is a longitudinal study on 26
consecutively referred male smokers aged 39-66 yrs. Each performed the two-step
stool test on two 15-cm steps at 10, 20, 30, 40, 50, and 60 climbs per minute.
Exertional dyspnea, oxygen consumption per unit time, ventilation, respiratory
rate, tidal volume, heart rate, capillary oxyhemoglobin saturation, physiologic
cost index, and oxygen pulse were recorded and compared with those observed
during incremental cycle exercise (30 W per 3 mins). Multivariate analysis for
each parameter was undertaken as a mixed model. RESULTS: All subjects attained 60
climbs per minute on the two-step stool test and performed 38-42 mins of two-step
stool endurance. All parameters reached 80%-96% of cycle maximum oxygen
consumption. The subjects found the two-step stool endurance simple and practical
to perform at home. There were no complications. CONCLUSIONS: The incremental
two-step stool test is a simple, cost-effective way to establish a 45-min
maximally intensive endurance exercise training program practical for use in the
home.
