Abstract
Objective Athletes are under physical and mental stress on a daily basis such as high intensity exercise, game stress, etc., and the importance of maintaining good condition has been mentioned. Euglena gracilis EOD-1 is a kind of microalgae, contains over 50 kinds of various nutrients and 70% to 80% of β-1,3-glucan called paramylon which is unique component in Euglena species. EOD-1 strain contains more paramylon than other Euglena sp., so it is gathering attention as functional food. Recent studies suggest that salivary and blood of human contain the immunoglobulins which react the paramylon from EOD-1 strain, thus EOD-1 strain is expected to contribute to human immune function. Methods We evaluated the effect of EOD-1 strain intake on rugby players during the season. Thirty-six male rugby players were subjected to the tests in open-label trial. They were given the supplement contain EOD-1 strain dried powder(500 mg)daily for the season. Results By intake of the supplement contain EOD-1 strain dried powder was significant increased salivary testosterone compared with before ingestion and reduced a physical fatigue feeling. The rate of immunoglobulin secretion was maintained during the top league. Conclusions It was suggested that the intake of Euglena gracilis EOD-1 strain is useful for athletes who exercise vigorously on a daily. (UMIN ID: UMIN000028531)
