Short-time high-intensity exercise increases peripheral BDNF in a physical fitness-dependent way in healthy men

BDNF is associated with brain health and positively modulated by exercise; however, the influence of physical fitness status on BDNF is incipient. This study investigated the BDNF response after acute-exercise sessions performed at low, moderate, and high intensities and the relationship between phy...

Description
Summary:BDNF is associated with brain health and positively modulated by exercise; however, the influence of physical fitness status on BDNF is incipient. This study investigated the BDNF response after acute-exercise sessions performed at low, moderate, and high intensities and the relationship between physical fitness status and BDNF response. Twenty-eight men, divided according to physical fitness status (50th percentile for VO 2max ), performed three randomised acute exercise sessions at low (90% of VT1), moderate (midpoint between VT1-VT2), and high (midpoint between VT2-W max ) intensities until exhaustion or for up to 60 min. Lactate and BDNF were determined pre and post-exercises. For BDNF, there were main effects of time (p = 0.003) and interaction (p
