High-intensity interval training (HIIT) has proven to be a time-saving and efficient exercise strategy. Compared with traditional aerobic exercise, it can provide similar or even better health benefits. In recent years, a number of studies have suggested that HIIT could be used as a potential exercise rehabilitation therapy to improve cognitive impairment caused by obesity, diabetes, stroke, dementia and other diseases. HIIT may be superior to regular aerobic exercise. This article reviews the recent research progress on HIIT with a focus on its beneficial effect on brain cognitive function and the underlying mechanisms. HIIT may become an effective exercise for the prevention and/or improvement of brain cognitive disorder.

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.

Acute coronary syndrome (ACS),with increasing mortality year by year,has become a major public health problem in China.Exercise rehabilitation as an important part of the out-of-hospital rehabilitation for the patients with heart diseases can further reduce the mortality of patients on the basis of drug treatment.The available studies have proved that high-intensity interval training (HIIT) is more effective and efficient than moderate-intensity continuous training (MICT) such as walking and jogging on chronic cardiovascular diseases such as heart failure,stable coronary heart disease,and hypertension and has high security.According to the latest research,HIIT can reduce the platelet response,mitigate myocardial ischemia-reperfusion injury,and increase the exercise compliance of ACS patients more significantly than MICT.Moreover,it does not increase the risk of thrombotic adverse events or malignant arrhythmia.Therefore,HIIT is expected to become an important part of exercise prescription in out-of-hospital cardiac rehabilitation strategy for the patients with ACS.
