Aim: Evaluating climbing stairs for prescription and implementation of physical activity regimes. Methods: Healthy females F, n = 14, and males M, n = 15 participated. By climbing 100 steps of stairs with 0.173 m height, Heart rate HR and oxygen uptake were measured throughout the floors; Blood pressure BP was measured at ground and the 5th floors only. Results: Energy increased from 2 to 7.6 was metabolic equivalents METs = 3.5 ml O2-min.kg at 17.3 m elevation in 2 min. at the 5th floor, and percent Heart Rate Reserve %HRR was 66.17% in F and 48.7% in M, proportional to their aerobic efforts. Average climbing efficiency was 15.8 ± 2.3% n = 29. Aerobic capacity estimated dividing the highest work rate 17.3 Kg.m-2min.Kg × 0.00239 = 0.0207 Kcal-min.Kg, by fractional effort F = 0.6617, M = 0.487 and fractional efficiency 0.158, at 5 Kcal-L O2 was 0.040 in F and 0.054 L O2-Kg.min in M. Minimum training intensity reached at the 3rd floor by F. In M the highest %HRR reached was 48.7% at the 5th floor, insufficient for training. Conclusions: Stairs used for submaximal evaluation of aerobic capacity and for target intensity prescription. Training, levels climbed, repetitions per day if 5, 100 Kcal per day, ascending and number of days-week are adjusted. Full regime requires up to 7.6 METs, a total of 532 and 140 MET.min-week ascending and descending, respectively. Intensities >7.6 MET, climbing rate should be >8.65 m-min. Limiting ascent to 1 3.5 METs or 2 5.5 METs floors or only descents 2 - 3 METs may be used for unfit subjects. This method is useful for those with no access to sophisticated facilities.
