摘要

背景和目的：我们研究了短时间、高强度爬楼梯对韩国年轻肥胖男性心肺健康（CRF）和心脏代谢危险因素的影响。方法与结果：24名健康男性（年龄：25.8±2.4岁，BMI: 27.1±2.5 kg/m2）随机分为爬楼梯运动组（n = 12）和对照组（无运动干预，n = 12）。爬楼梯运动（每周5天，持续4周）包括3分钟的热身，然后是3次20秒的剧烈爬楼梯[≥80%的年龄预测最大心率（MHR）]，中间有2分钟的恢复时间。用最大踏车试验和生物电阻抗分析分别测定各组动物的最大摄氧量（VO2peak）和体成分。禁食10小时后采集空腹血液样本，测量心脏代谢标志物。所有参与者都完成了研究，并参加了97.1%的计划锻炼。CRF组间存在显著的时间效应，其中爬楼梯运动组VO2peak（运动前：38.7±5.2 ml/kg/min vs .运动后：41.6±5.7 ml/kg/min）和p2peak（运动后：41.6±5.7 ml/kg/min）显著改善，运动时间无变化。爬楼梯运动后，体重、体脂和代谢指标没有变化。结论：每天10分钟的短时间高强度爬楼梯对改善年轻肥胖男性的vo2峰值是有效的。临床试验注册：KCT0008139。

Effect of brief intense stair climbing on cardiorespiratory fitness and metabolic risk factors in inactive young men with obesity: A randomized controlled trial

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 (VO_2peak) 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 VO_2peak (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 VO_2peak 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 VO_2peak in young men with obesity.

期刊介绍： Nutrition, Metabolism & Cardiovascular Diseases is a forum designed to focus on the powerful interplay between nutritional and metabolic alterations, and cardiovascular disorders. It aims to be a highly qualified tool to help refine strategies against the nutrition-related epidemics of metabolic and cardiovascular diseases. By presenting original clinical and experimental findings, it introduces readers and authors into a rapidly developing area of clinical and preventive medicine, including also vascular biology. Of particular concern are the origins, the mechanisms and the means to prevent and control diabetes, atherosclerosis, hypertension, and other nutrition-related diseases.
