A new study1 has shown that anthocyanin-rich CurraNZ can improve performance relating to dynamic speed and agility in Rugby Union players.
This study shows for the first time how blackcurrant can improve dynamic performance tasks, but not strength or power, in a series of rugby-specific tests. The findings also have implications for other team-based running sports such as football, hockey and basketball.
Thirteen University and Club-level Rugby Union players were assessed following a week’s supplementation of 600mg CurraNZ blackcurrant extract, in a double-blind, placebo-controlled, randomised crossover study design.
The male participants executed a running-based anaerobic sprint test, the Illinois Agility test, seated medicine ball (3kg) throw and hand grip strength task.
Findings showed that CurraNZ:

In repeated sprint tests, a performance improvement above 1.8% is considered a meaningful change.
