No Effect of Acute or Chronic New Zealand Blackcurrant Extract on Cycling Performance or Physiological Responses in Trained Cyclists.

Previous research examining the ergogenic benefits of blackcurrant supplementation (BC) on exercise performance is contradictory. The BC supplementation period in many studies has typically been chronic (> 6-days), with a final dose taken hours before testing. Whether any observed performance benefits are from the acute dose or chronic supplementation is unclear.
