Effects of a 12-week high intensity interval training on blood lipid of dyslipidemia patients with different apolipoprotein E genotypes / 中国应用生理学杂志

ABSTRACT

OBJECTIVE@#To evaluate the effects of 12 weeks high intensity interval training(HIIT) on serum lipids profile in patients with dyslipidemia of different apolipoprotein E(ApoE) genotypes.@*METHODS@#Eighty-eight patients with dyslipidemia were screened by fasting blood lipid as subjects. Apolipoprotein E genotypes were detected in oral mucosa of subjects. Serum lipids before and after 12 weeks high intensity interval training were measured to analysis the effect of high intensity interval training on serum lipids.@*RESULTS@#Five genotypes were detected in 88 cases of dyslipidemia. The distributions were ApoE3/3＞ApoE3/4＞ApoE2/3＞ApoE2/2＞ApoE2/4,and allele ε3＞ε2=ε4. Before exercise intervention, the level of total cholesterol in patients with ε4 allele was significant higher than those in patients with ε2 and ε3 (P＜0.01), low density lipoprotein cholesterol in patients with ε4 was significant higher than that of patients with ε2 (P＜0.05), and the other indexes had no significant difference among the groups (P＞ 0.05). After 12 weeks high intensity interval training, the levels of total cholesterol, triglyceride and low density lipoprotein cholesterol were decreased significantly ,while the level of high density lipoprotein cholesterol was increased in those patients with ε3 genotype. For those individuals with ε4 genotype , their serum levels of total cholesterol and low density lipoprotein cholesterol were reduced after 12 weeks high intensity interval training , but there was no changes in serum levels of triglyceride and high density lipoprotein cholesterol. For those individuals with ε2 genotype, there was no significant improvement in serum lipids after 12 weeks high intensity interval training interventions.@*CONCLUSION@#The polymorphisms of apolipoprotein E gene resulted in different effects of exercise interventions on serum lipids of dyslipidemia. Twelve weeks high intensity interval training can be used as an intervention method to regulate serum lipids of dyslipidemia with ε3 and ε4 alleles.
