Effect of New Zealand Blackcurrant on Performance during the Running Based Anaerobic Sprint Test in Trained and Recreational Football Players


  • Study tested 600mg CurraNZ blackcurrant extract on 15 recreational and nine Professional Academy Youth football players to investigate whether blackcurrant extract would improve performance during repeated, high-intensity sprints 
  • Blackcurrant had a clear effect on the trained players, who experienced less slowing in the sprint tests
  • Trained footballers had reduced slowing of sprint times, an effect not observed in the non-elite players
  • 12 of the 24 players (including five of the nine Academy players) demonstrated a lower fatigue index by a combined absolute value of 12%, calculated on the change in maximum power to the slowest sprint
  • Trained footballers benefited more from New Zealand blackcurrant extract supplementation in exhaustive running test with long recovery times
