Background: The study aimed to evaluate the effects of a 4-week Bergamot Polyphenolic Fraction (BPF Gold; Bergamet Sport) supplementation on serum nitric oxide (NO), asymmetric dimethyl-arginine (ADMA), Endopat indices of endothelial function and maximal oxygen uptake (V_ O2max) of athletes.

Methods: The effects of dietary supplementation (BPF Gold, 650 mg twice a day for 4 weeks) and placebo administration on flow-mediated dilatation (via Endopat measurements), serum markers (NO, ADMA), lipid profile, and V_ O2max were analysed in 30 athletes both before and after dietary protocols.

Results: Significant differences between pre- and post-intervention baseline NO levels were observed after BPF Gold dietary protocol. Higher post-intervention baseline NO level was observed after BPF Gold diet compared with placebo. Moreover BPF Gold Sport increased baseline NO concentration (ΔNO). The positive correlation was observed between baseline post-intervention NO concentration and maximal oxygen uptale and also between ΔNO and ΔVO2max in response to BPF Gold supplementation. There was an association between a higher Edopat values of endothelial function and higher V O2max after Bergamet Sport diet compared with lower values of placebo.

Conclusions: These findings suggest that an increase in NO release in response to BPF Gold Sport supplementation may play a central role in cardiovascular adaptive mechanisms and enhanced exercise performance in athletes.
