OBJECTIVES This study analyzed the possibility of brain function activation after exercise training of highintensity interval exercise and moderate-intensity continuous exercise in elderly people. METHODS The subjects of the study were elderly female people aged 65 years or older and were divided into three groups : control group, moderate-intensity continuous training (MICT), and high-intensity interval training (HIIT). Changes of body composition, physical fitness, cognitive function, and cognitive functionrelated blood variables were compared between before and after 12 weeks of exercise training. RESULTS Body weight, BMI (body mass index), and WHR (waist hip ratio) of body composition in HIIT group decreased significantly (p<0.05) after exercise training, and there was no significant difference in MICT group and the control group. HIIT group significantly (p<0.05) improved in grip strength, muscular endurance, flexibility, balance, cardiorespiratory endurance, and walking ability after exercise training, while MICT group showed significant (p<0.05) improvements only in flexibility, balance, and cardiorespiratory endurance. Regarding blood variables, HIIT group showed significant (p<0.05) differences in BDNF (brainderived neurotrophic factor), irisin, and β-amyloid after exercise training, MICT group showed significant (p<0.05) differences only in β-amyloid. Cognitive function in HIIT group and MICT group significantly (p<0.05) improved in terms of temporal and spatial orientation, memory, and total scores after exercise training. During the recovery phase after one session of high-intensity interval exercise, blood lactic acid concentration increased significantly. CONCLUSIONS This study was confirmed the possibility of giving that high-intensity interval exercise for the elderly not only produces positive changes in body composition and improves physical fitness and cognitive function, but also frequently stimulates lactate production, helping to activate brain function through changes in BDNF and irisin in the blood.
