Oligonol versus cortisol
Intense training is fine, but each session also causes your body a lot of physical stress. This explains the increase in the concentration of stress hormone and inflammatory factors in the body after a session. Supplementation with the lychee extract Oligonol softens these stress reactions.
Study
9 students in a control group were given a placebo.
Oligonol is an extract of lychees, which is marketed by the Japanese Amino Up Chemical Company. We have been writing about Oligonol with some frequency for several weeks now. An overview of these posts can be found here.
Our interest is mainly motivated by our pleasant surprise at the amount of scientific literature available on this product. There aren't as many supplement components that have been studied as thoroughly as Oligonol.
Most of the Oligonol studies we've written about were sponsored by Amino Up. This is not the case with the South Korean study we are now talking about. This study is funded by the Korean government.
Results
On this last day, the students had to run for 60 minutes on a treadmill at an intensity of 75 percent of their maximum oxygen uptake. Just before and after the session, the researchers again took blood samples.
Supplementation with Oligonol lowered the concentration of cortisol and that of the measured inflammatory factors both at rest and immediately after physical exertion.
The researchers also looked at the white blood cells, but saw no effect of supplementation.
