Lemon verbena extract accelerates muscle recovery after training
Supplementation with Recoverben, which contains an extract of the leaves of the lemon verbena, accelerates muscle recovery after intensive training. Whether Recoverben also accelerates muscle growth? That is not clear from the human study published by German researchers in the Journal of the International Society of Sports Nutrition. But you would think so.
Recoverben is a product of German Vital Solutions. [vitalsolutions.biz] The research in the Journal of the International Society of Sports Nutrition is carried out and financed by that company.
Recoverben is already on the market. It is one of the many ingredients in Zeus' EliteSport
In Recoverben contains a water based extract of the plant Aloysia citriodora or lemon verbena. Aloysia citriodora originates from South-America, but is now grown worldwide. Tea from the leaves softens colds, reduces abdominal pain and has a calming effect. The bioactive substances in Aloysia citriodora, like carvone and thujones, are also found in citrus fruits.
The researchers divided 44 active men and women aged 22-50 into two groups. One group took a placebo every day for 15 days, the other 400 mg Recoverben.
After 10 days the subjects had to make 10 sets of 20 jumps. In the 4 days thereafter, the researchers monitored the subjects.
After the training session, in all subjects the strength that their leg muscles could develop with a leg extension was diminished. The recovery was considerably faster in the Recoverben group.
In the blood of the subjects who had used Recoverben, the researchers found less creatine kinase after the training session. More creatine kinase means more and more severe damage in muscle tissue.
"During the current study, glutathione peroxidase in plasma was selected as a parameter to supply information about antioxidative capacity", the Germans wrote. "Our results indicate an activation of the antioxidative defense under lemon verbena extract by up-regulating glutathione peroxidase shortly after exercise."
"In contrast to this, baseline glutathione peroxidase was not increased by supplementation with lemon verbena extract. Therefore, it appears, that supplementation with lemon verbena extract strengthens the antioxidative defense system and enables effective counteraction of oxidative stress, but only if needed."
"In summary, our study showed that ingestion of a 400 mg/day proprietary lemon verbena extract (Recoverben) resulted in significantly less muscle strength loss in healthy, moderately active adults", the researchers wrote. "Influences by trend on muscle soreness and antioxidative capacity emphasizes the potential of the product accelerating recovery after exhaustive exercise."
