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).
