    Elite footballers can better maintain fastest maximum sprint times with 600mg CurraNZ

    on April 26, 2021

    A STUDY by the University of Chichester has shown that CurraNZ New Zealand blackcurrant extract improves running performance in footballers by allowing them to better maintain fastest maximum sprint times.

    Researchers examined whether short-term supplementation of blackcurrant extract would improve performance during repeated, high-intensity sprints in elite and non-elite footballers.

    The results showed: 

    •  Elite footballers experienced less slowing in the high-intensity, repeated sprint tests
    • Elite players 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 elites) demonstrated a lower fatigue index by a combined absolute value of 3.5%, calculated on the change in maximum power to the slowest sprint


    The double-blind, randomized, cross-over study used a running-based anaerobic sprint test (RAST), consisting of 6 x 35-metre sprints with ten seconds of recovery. The exhaustive test is designed to assess anaerobic performance and measure power and fatigue. 

    The study involved 15 non-elite University team football players and nine elite players from an English professional club youth team.

    Players consumed 600mg of New Zealand blackcurrant anthocyanin extract, CurraNZ, for seven days leading up to, and including, testing.
     
    Mark WillemsProfessor of Exercise Physiology at the University of Chichester, says: “We want to get a better understanding of the specific exercise conditions under which blackcurrant works for athletes.

    “We have shown that blackcurrant is beneficial for endurance athletes and for sports that require high-intensity, repeated bursts of activity with long recovery times.

    “This study represented an exhaustive running test with long recovery times and the blackcurrant clearly worked under those conditions.

    "There was a strong message that elite football players tended to benefit more from blackcurrant supplementation.”
