BACKGROUND AND AIM: We investigated the effects of brief, intense stair climbing on cardiorespiratory fitness (CRF) and cardiometabolic risk factors in young Korean men with obesity.
METHODS AND RESULTS: Twenty-four healthy men (age: 25.8 ± 2.4 years, BMI: 27.1 ± 2.5 kg/m2) were randomized into either the stair climbing exercise group (n = 12) or the control group (no exercise intervention, n = 12). The stair climbing exercise (5 days per week for 4 weeks) included a 3-min warm-up, followed by three 20-s bouts of vigorous stair climbing [≥80 % of age-predicted maximal heart rate (MHR)], with 2-min of recovery in between. Peak oxygen uptake (VO2peak) and body composition were measured by maximal treadmill test and bioelectrical impedance analysis, respectively. A fasting blood sample was obtained after a 10-h overnight fast to measure cardiometabolic markers. All participants completed the study and attended 97.1 % of all scheduled exercise sessions. There was significant group x time effect on CRF, such that the stair climbing exercise group had significant improvements in VO2peak (pre: 38.7 ± 5.2 versus post: 41.6 ± 5.7 ml/kg/min, P < 0.01) and exercise duration (pre: 10.4 ± 1.8 versus post: 12.1 ± 1.9 min, P < 0.01) during a maximal treadmill test, but with decreases in VO2peak and no change in the exercise duration the control group. Body weight, body fat and metabolic variables were unchanged after stair climbing exercise.
CONCLUSION: Brief, intense stair climbing with a total time commitment of 10 min per day is effective for improving VO2peak in young men with obesity.
