摘要

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。

Abstract: 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 4-week 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=16.19, 16.21, 12.42, 7.99, 2.10, 6.37; 18.82, 18.02, 17.80, 10.72, 3.41, 7.59, 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 4-week 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=10.15, 8.94, 6.94, 7.63; 9.23, 12.75, 9.85, 9.09, P < 0.01), and increased the high-density 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 short-term 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.
