Relatively high-intensity exercise increases protein expression of tropomyosin receptor kinase B (TrkB) and brain-derived neurotrophic factor (BDNF). (A) Detected image of Western blot. (B) The protein expression of TrkB and BDNF was significantly higher than that of all other groups. Data are presented as mean±standard deviation. HFD, high-fat diet; LIE, low-intensity exercise; MIE, middle intensity exercise; HIE, high-intensity exercise. **P<0.01 and ***P<0.001 for TrkB. ^†P<0.05 and ^§P<0.001 for BDNF.
