摘　　要：目的:探索高强度运动对静坐少动生活方式(sedentary lifestyle,SDLS)人群代谢应答的影响。方法:对14名SDLS大学生进行为期6周的高强度运动(4~5次/周)干预,每次练习密度为50%~60%,运动强度高于80%HR_(max),每次练习时间为50~90 min,分别在运动前后测试身体形态机能指标,在干预前和干预后24 h收集晨尿用于差异代谢物分析。结果:SDLS大学生进行6周高强度运动可以显著提高VO2_(max)、立定跳远和坐位体前屈等体质健康指标的成绩;运动前、后对尿代谢组学分析,筛选和鉴定出17种差异代谢物,经ROC曲线分析,显示差异代谢物具有良好的诊断力。结论:研究筛选和鉴定出的17种差异代谢物与SDLS大学生6周高强度运动后的代谢应答变化有关。差异代谢物涉及了脂肪酸、胆固醇和支链氨基酸等代谢途径,高强度运动引起的这些代谢途径的改善可能与SDLS大学生获得的有氧能力提升以及有益的健康适应有一定关联。Objective:To explore the effect of high intensity exercise on the metabolic response of sedentary lifestyle.Methods:Fourteen sedentary lifestyle students underwent a 6-week high intensity exercise intervention.Each practice training density was 50%~60%,intensity was higher than 80%of maximum heart rate,each practice time was 50~90 min.Morphological function indicators were tested before and after exercise,morning urine was collected for differ‐ential metabolite analysis before and 24 hours after intervention.Results:Six-week high intensi‐ty exercise in sedentary lifestyle students significantly improved VO2_(max),scores of physical health indicators such as standing long jump and sit-and-reach;analyzing urinary metabolomics before and after exercise,screening and identifying 17 differential metabolites,it showed that differential metabolites have good diagnostic power by ROC analysis.Conclusion:The 17 dif‐ferent metabolites screened and identified in this study were related to the metabolic response of sedentary lifestyle college students after 6 weeks of high intensity exercise.Differential metabo‐lites involve metabolic pathways such as fatty acids,cholesterol and branched-chain amino ac‐ids,the improvement of these metabolic pathways caused by high intensity exercise may be re‐lated to the improvement of aerobic ability and beneficial health adaptation of sedentary life‐style college students.
