The peripheral blood flow is crucial for the oxygen supply of the muscles
The peripheral blood flow, i.e. circulation in the outer zones of the body, is decisive for the oxygen supply of the muscles. Studies have shown that especially plant extracts rich in anthocyanins lead to blood vessel relaxation and expansion, and thus improve microcirculation. This effect positively influences substrate availability during competition, performance and the athletes' ability to recover.
