摘　　要：目的了解生酮饮食(KD)和生酮饮食结合抗阻训练(KD+RT)对肥胖女大学生身体成分及糖脂代谢的影响,为KD+RT应用于肥胖患者提供理论依据。方法于2021年9月在武夷学院招募45名肥胖女大学生分为KD组(23名)及KD+RT组(22名),在接受训练方案4周后,比较干预前后肥胖女大学生身体成分及糖脂代谢的变化。结果4周KD与KD+RT均降低了肥胖女大学生体重、体质量指数(BMI)、体脂肪量、体脂百分比、腰臀比及内脏脂肪面积(t值分别为16.19,16.21,12.42,7.99,2.10,6.37;18.82,18.02,17.80,10.72,3.41,7.59,P值均<0.01);KD组肌肉质量下降(t=4.12,P<0.01),KD+RT组肌肉质量变化无统计学意义(P>0.05)。4周KD与KD+RT均降低了肥胖女大学生空腹血糖、空腹胰岛素、糖化血红蛋白、三酰甘油水平(t值分别为10.15,8.94,6.94,7.63;9.23,12.75,9.85,9.09,P值均<0.01),升高高密度脂蛋白水平(t值分别为-7.36,-5.22,P值均<0.01);仅有KD+RT组低密度脂蛋白水平下降(t=5.27,P<0.01),总胆固醇水平差异均无统计学意义(P值均>0.05)。干预后,与KD组比较,KD+RT组除三酰甘油水平下降外(t=2.51,P<0.05),其他指标两组间差异均无统计学意义(P值均>0.05)。结论短期的KD及KD+RT均使肥胖女大学生身体成分和糖脂代谢显示了有益的变化,但KD+RT在保持肌肉质量及降低脂质代谢方面优于KD干预。Objective To investigate the effects of a ketogenic diet KD alone and in combination with resistance training KD+RT on body composition and glucolipid metabolism of obese and female college students and to provide a theoretical basis for the application of KD+RT in obese patients.Methods Totally 45 obese and female college students in Wuyi University were recruited and randomly divided into KD group n=23 and KD+RT group n=22 in September 2021.After received training for 4 weeks the changes of body composition and glucose and lipid metabolism of obese and female college students were compared before and after intervention.Results Both a 4week KD and KD+RT led to decreases in weight BMI body fat mass body fat percentage waist to hip ratio visceral fat area of obese female college students t=16.1916.2112.427.992.106.3718.8218.0217.8010.723.417.59 P<0.01.The change of muscle mass was decreased in KD group t=4.12 P<0.01 but there was no statistically significant difference in KD+RT group P>0.05.Both a 4week KD and KD+RT significantly reduced the levels of the fasting blood glucose fasting insulin glycosylated hemoglobin and triglyceride TG of obese female college students t=10.158.946.947.639.2312.759.859.09 P<0.01 and increased the highdensity lipoprotein HDL level t=-7.36-5.22 P<0.01.However only KD+RT group had a significant decrease in the level of LDL t=5.27 P<0.01 and there was no significant change in the level of TC both groups P>0.05.After the intervention there was no statistically significant difference between the KD+RT group compared to the KD group P>0.05 except for a significant decrease in triacylglycerol t=2.51 P<0.05.Conclusion Both a shortterm KD and KD+RT show beneficial changes in body composition and glucolipid metabolism in obese female college students.However the KD+RT is superior to a KD in maintaining muscle mass and reducing the effects of lipid metabolism.
