摘要

摘要: 目的了解男大学生蹬楼梯能量代谢的特点和差异，为指导大学生减少久坐时间和采取更健康的生活方式提供参考。方法在北京高校，招募24名20~30岁男大学生，受试者依体质量指数(BMI)分为正常体重组与超重组。静息和负重蹬楼梯状态下的能量消耗由Cortex 3B便携式气体代谢分析仪测得。负重负荷为0~5 kg。结果超重组男大学生负重5 kg上楼梯时的能量消耗大于负重0 kg时(F=9.44)，正常体重组负重4和5 kg上楼梯时的能量消耗大于负重0 kg时(F=7.47)(P值均 < 0.05)。超重组男生负重3 kg、正常体重组负重4 kg上楼梯时，单位体重净能量消耗大于负重0与1 kg时(F值分别为3.39，3.79)(P值均 < 0.05)。相同负重条件下，超重组与正常体重组上楼梯时能量代谢指标都大于下楼梯时。结论超重男大学生以中等负重(3 kg)上楼梯，正常体重男大学生以较大负重(4与5 kg)上楼梯利于达到增加单位净能量消耗、控制体重的目的。

Abstract: Objective To explore the characteristics and differences of energy expenditure of stair climbing in male university student with different BMI groups and under varying load capacity. Methods A total of 24 male university students aged 20 to 30 years were recruited from universities in Beijing. Participants were divided into normal weight group and overweight group according to BMI. The energy expenditure of climbing stairs and rest energy expenditure were measured by Cortex MetaMax 3B portable gas metabolic analyzer. The load for climbing stairs from 0 to 5 kg. Results The energy expenditure during stair climbing with a load of 5 kg in overweight group was significantly greater than without load (F=9.44, P < 0.05). Greater physical load is needed for the same energy expenditure among overweight male university students than normal weight students. The energy expenditures during stair climbing with loads of 4 kg and 5 kg in normal weight group were significantly greater than without load (F=7.47, P < 0.05). The net energy expenditures per unit weight during stairs climbing carrying 3 kg load in overweight group and 4 kg load in normal weight group were significantly higher than without load and load with 1 kg (F=3.39, 3.79, P < 0.05). When climbing up stairs with same load, the energy expenditure in both overweight and normal weight group were greater than those of stair descending. Conclusion Stair climbing with mderate load (3 kg) for overweight male students, and higher load (4-5 kg) for normal weight male student are needed for weight control.
