Abstract/Description
BDNF is a neurotrophin that enhances neural health and is increased by exercise. PURPOSE: To compare moderate continuous (MCE) and high-intensity interval exercise (HIE) effects on serum BDNF levels, and examine the relationship between BDNF and lactate. METHODS: Seven males completed a VO2peak test and two protocols on separate days, (MCE) 28 min at 60% Workrate max (WRmax) and (HIE) 28 min of intervals at 90%WRmax (10- 1 min intervals separated by 2 min of rest). Serum BDNF and lactate were...

PURPOSE: To compare moderate continuous (MCE) and high-intensity interval exercise (HIE) effects on serum BDNF levels, and examine the relationship between BDNF and lactate. METHODS: Seven males completed a VO2peak test and two protocols on separate days, (MCE) 28 min at 60% Workrate max (WRmax) and (HIE) 28 min of intervals at 90%WRmax (10- 1 min intervals separated by 2 min of rest). Serum BDNF and lactate were determined prior, during, and following both protocols. RESULTS: BDNF levels (pg/mL) increased from baseline during HIE and MCE (p<.05). The BDNF response to HIE correlated with lactate for area under the curve (AUC) (r=0.901; P<0.05). CONCLUSION: HIE is an effective alternative to MCE at increasing BDNF. Additionally, lactate may act as a measure of intensity or a mediator of the BDNF response to exercise.
