“…Furthermore, others have shown the high cardiopulmonary stress imposed by stair climbing. Previous studies have shown that in patients with chronic airflow obstruction [24] and chronic heart failure [25], stair climbing represents strenuous exercise, eliciting physiological responses similar to cycle ergometry and treadmill tests.…”

Exercise training is an essential component of pulmonary rehabilitation. However, the cardiopulmonary stress imposed during different modalities of exercise training is not yet known.In the present study, the cardiopulmonary stress of a 12-week exercise training programme in 11 chronic obstructive pulmonary disease (COPD) patients (forced expiratory volume in one second 42¡12%pred, age 69¡6 yrs) was measured. Pulmonary gas exchange and cardiac frequency (fC) of three training sessions were measured with a portable metabolic system at the beginning, mid-term and end of the programme. Symptoms were assessed with Borg scores.The exercise intensity was compared with the recommendations for exercise training by the American College of Sports Medicine (ACSM). Training effects were significant (maximum change in work: 14¡11 Watts, 6-min walk test: 44¡36 m). Whole body exercises (cycling, walking and stair climbing) consistently resulted in higher cardiopulmonary stress (oxygen uptake (V9O 2 ), minute ventilation and fC) than arm cranking and resistance training. Dyspnoea was higher during cycling than resistance training. Patients exercised for .70% (.20 min) of the total exercise time at .40% of the V9O 2 reserve and fC reserve (''moderate'' intensity according to the ACSM) throughout the programme.The cardiopulmonary stress resistance training is lower than during whole-body exercise and results in fewer symptoms. In addition, exercise testing based on guidelines using a fixed percentage of baseline peak performance and symptom scores achieves and sustains training intensities recommended according to the American College of Sports Medicine.

“…Thus, stair climbing can provide economical aerobic training without specialized equipment [17][18][19][20] and has been recommended to alleviate America's and Europe's obesity epidemic [1,6,9,17]. However, studies to date have been limited by heterogeneity of stair climbing protocols and inadequate control of confounding factors [9,[17][18][19][20].…”

“…For patients with chronic airflow limitations, going up steps is an exhausting exercise and it leads to a physiological response in terms of VO 2 , V E , heart rate and related symptoms that are similar to the responses in maximum tests 37,38 . Although the step test is simple, cheap and easy to apply, few studies have chosen step tests to evaluate physical capacity among individuals with airflow limitations.…”
