This latest study, carried out at the University of Surrey in the UK, used our CurraNZ blackcurrant supplement in a double blind placebo trial to test its recovery benefits.
SYNOPSIS (STUDY SUMMARY)
A study on 27 non resistance-trained men and women took 300mg (1 capsule) of CurraNZ seven days leading up to the bout of strenuous isokinetic resistance exercise focusing on the bicep, then an hour beforehand, and four days following testing.
The findings showed:
Exercise-induced muscle damage (EIMD) typically involves two phases of recovery. The first phase is a disruption to muscle fibres followed by a rise in inflammation, swelling and oxidative stress. These secondary events lead to additional tissue damage and the release of toxic by-products, which results in impaired muscle function and pain, also known as delayed onset muscle soreness (DOMS).
Blackcurrant reduced the release of creatine kinase (a protein that leaks out of damaged muscle tissue into the circulation) by 84% compared to placebo at 96 hours post exercise, indicating the berry’s compounds protected muscles from secondary tissue damage.
The use of anthyocyanin-rich foods and supplements have become popular for aiding post-exercise recovery in active people in recent years. However, the majority of studies on anthocyanin and antioxidant-rich interventions, such as beetroot, blueberry, tart cherry and pomegranate, have shown no effect on creatine kinase, a common measure to assess EIMD.
However, in this study, CurraNZ® proved very effective, which is attributed to its antioxidant scavenging and anti-inflammatory abilities.
This research is not alone in showing positive health and fitness benefits for CurraNZ. So far 30+ independent, peer reviewed studies have been published. Another study showed CurraNZ improved blood flow (in some cases, by up to 45%) by widening blood vessels - this helps explains other positives such as up-regulating oxygenation to muscles and improved exercise performance. Not only does CurraNZ aid recovery, it also helps improve energy and supports heavy exertion in hot environments. One supplement, many benefits, great value.
