功能性高强度间歇训练结合呼吸饮食对肥胖大学生的干预效果

Effect of functional high-intensity interval training combined with inhalation dietary intervention on obese college students

目的研究观察功能性高强度间歇训练结合呼吸、饮食干预对肥胖大学生身体形态、血脂和肝功能的影响,以期为完善相关干预措施提供参考。方法以重庆电信职业学院公开招募的58名肥胖大学生为研究对象,根据性别、身体质量指数(body mass index,BMI)的不同进行功能性高强度间歇训练、呼吸训练和饮食控制干预,研究持续6周。比较干预前后的BMI、体脂率、总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、非酒精性脂肪肝(NAFLD)、丙氨酸氨基转移酶(ALT)、天门冬酸氨基转移酶(AST)、γ-谷氨酰转移酶(GGT)等身体指标的变化情况。结果干预前后,受试者的身体形态指标:男女生的BMI、体脂率均下降(t值分别为7.57,4.40;4.17,5.61,P值均<0.01);男女生TC、TG、LDL-C均呈明显下降趋势,而HDL-C上升(t值分别为7.56,5.80;2.58,4.76;12.26,11.07;3.72,3.37,P值均<0.05);肝功能(男女合并人数):NAFLD、ALT异常、AST异常、GGT异常均明显减少(P值均<0.05)。结论该综合干预方法而言,可以显著降低肥胖大学生体重,能调节改善血脂代谢和肝功能,且干预过程体验较好,可作为肥胖大学生的一个有效减肥途径予以应用和推广。

Objective To observe the effect of functional high-intensity intermittent training combined with breathing and diet intervention on body shape,blood lipid and liver function of obese college students,so as to verify and improve the relevant intervention methods.Methods Fifty-eight obese college students recruited by Chongqing Telecom Vocational College were selected as participants.According to gender and body mass index(BMI),functional high-intensity intermittent training,breathing training and diet control intervention were carried out for 6 weeks.BMI,body fat percentage,total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),non-alcoholic fatty liver disease(NAFLD),alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma glutamyltransferase(GGT)and other physical indicators were compared before and after intervention.Results Before and after the intervention,the changes of body indexes were as follows:BMI,body fat percentage of male and female were significantly decreased(t=7.57,4.40;4.17,5.61,P<0.01);TC,TG and LDL-C of male and female were significantly decreased,while HDL-C increased significantly(t=7.56,5.80;2.58,4.76;12.26,11.07;3.72,3.37,P<0.05);NAFLD,abnormal ALT,abnormal ast,abnormal GGT were significantly reduced(P<0.05).Conclusion The comprehensive intervention method can significantly reduce body weight and regulate blood lipid metabolism and liver function in obese college students,and the intervention experience is better.It can be applied and promoted as an effective way to lose weight for obese college students.
