Effects of Aerobic Exercise and Resistance Training on Cognitive Function: Comparative Study Based on FNDC5/Irisin/BDNF Pathway

Exercise has been recommended to suppress or prevent cognitive decline. Aerobic exercise (AE) may suppress cognitive decline via the fibronectin type III domain-containing protein 5 (FNDC5)/irisin/brain-derived neurotrophic factor (BDNF) pathway, and resistance training (RT) has a preventive effect on cognitive decline. However, the underlying mechanism remains unclear. This study verified the differences in the effects of AE and RT in suppressing and preventing cognitive decline based on the FNDC5/irisin/BDNF pathway.
