Abstract/Description
The purpose of this study was to determine if resistance exercise altered peripheral BDNF concentration. Eighteen trained male subjects were split into two groups performing varied repetition ranges. DUP-HR and DUP-LR groups trained 3x/week for 8 weeks, and were equated for total volume (repetitions X sets X intensity). Plasma BDNF and interleukin-6 (IL-6) levels were measured prior to and immediately following the first exercise session of weeks 1, 2, 4 and 6. Pre-exercise levels were also...

Eighteen trained male subjects were split into two groups performing varied repetition ranges. DUP-HR and DUP-LR groups trained 3x/week for 8 weeks, and were equated for total volume (repetitions X sets X intensity). Plasma BDNF and interleukin-6 (IL-6) levels were measured prior to and immediately following the first exercise session of weeks 1, 2, 4 and 6. Pre-exercise levels were also assessed prior to the second and third sessions of week 1 and 6. Lastly, resting levels were measured before and after training intervention. No group differences (p>0.05) were detected for either biomarker. An acute BDNF elevation (p=0.018) was detected only in the final week of training. IL-6 elevations were detected at all acute measurements (p<0.01). BDNF and IL-6 percentage change correlated significantly (p<0.05) in week-1. No chronic alterations were observed (p>0.05).

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...
Show moreBDNF 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 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.
