From Dr Mark Willems, Professor in Exercise Physiology at the University of Chichester – Presented at The Blackcurrants NZ Conference, August 2015.
Take Home Facts from Recent Trials – Blackcurrants & Sport
1. New Zealand Blackcurrants improved time by 2.4% in a 16.1 km cycling time-trial performance.
Accepted for publication June 2015 –Cook et al, European Journal of Applied Physiology
2. New Zealand Blackcurrants increased ‘fat oxidisation’ aka ‘burning fat’ by 27% at exercise intensity of 65% when cycling. (show cycling pic)
Accepted for publication June 2015 – Cook et al, European Journal of Applied Physiology
3. Sujon New Zealand blackcurrant powder resulted in a complete shift of the lactate curve which you normally only get from months & months of endurance training. This complete shift was a 14% decrease in lactate, as shown in graph below.
Accepted for publication March 2015 – Willems et al., International Journal of Sport Nutrition and Exercise Metabolism.
4. In a repeated sprints study, New Zealand blackcurrants improved sprinting distance by 11%.
Accepted for publication March 2015, Perkins et al., International Journal of Sport Nutrition and Exercise Metabolism
New Zealand Blackcurrants were only taken for a 7 day period in all of Prof Willems trials. The dose was 6gm of Sujon Blackcurrant Sport powder.
The Question Professor Willems now wants to answer is what is the optimal dosing of New Zealand Blackcurrants in Sports performance?
“Endurance and team sport athletes may consider intake of New Zealand blackcurrant to beneficially enhance training practice, performance and recovery.”

Research on Blackcurrants and Sport So Far
Before 1995 there were virtually no scientific papers on anthocyanins that are also present in blackcurrants. From 1995 – 2015 we see an explosion of study with nearly 6748 scientific papers on anthocyanins alone, as shown below.
And the studies on ‘Anthocyanins’ and ‘Exercise’ were zero until sometime after 1995. We have still only a mere 23 scientific papers up to 2015, of which only a handful on the effects of blackcurrant.
Studies at the University of Chichester were the first on effects of New Zealand blackcurrant during exercise.
So we can see that while we now have good handle on blackcurrants and their health benefits; we are only beginning to fully understand, as scientists and sports-people, the true benefits of blackcurrants in sport.
