The goal of this observational study is to study the effect of gene polymorphism on cognitive improvement in response to exercise in healthy participants. The main questions it aims to answer are: To investigate whether FNDC5/Irisin genotype polymorphism affects cognitive function and inter-individual variability in exercise response. To explore whether the FNDC5/Irisin gene polymorphism can act alone or interact with the BDNF gene to cause inter-individual differences in cognitive function responses to exercise gain. Participants will be asked to perform high-intensity interval training( HIIT) on a cycle ergometer. Each high-intensity training period will be 30 seconds followed by a 4-minute rest period. The participants will also perform cognitive tests (Vistorian stroop test and Fitlight trainer test) before and after the exercise.

Exercise has a significant effect on improving brain function. It can improve cognitive function, enhance learning effects, and prevent the occurrence of neurodegenerative diseases in the elderly. Exercise's mechanism of action to improve cognitive function includes stimulating the nervous system to secrete brain-derived neurotrophic factor (BDNF) and skeletal muscle to secrete irisin. However, the effect of exercise on improving physical function varies from person to person. This phenomenon is called inter-individual exercise response variability. Genetic differences may be responsible for this phenomenon. The genotype differences of BDNF and Irisin can cause cognitive function. However, the scientific community is still unclear whether the differences between the two genotypes are related to individual differences in exercise responses. The investigators suspect that genotype might be responsible for interindividual variability in motor responses and therefore designed this experiment to test this thesis. This study is expected to recruit 200 healthy adults to complete the genotype sequencing of BDNF and Irisin and use the cognitive function responses before and after a single high-intensity interval aerobic exercise to establish the model that genotype affects the variability of individual exercise responses. The experimental results of this study can help the scientific community understand the influence of genotype on individual differences in exercise response and further explore and refine the design of exercise prescription.
