Professor Ryo Inoue and Professor Mami Fujibayashi of the Faculty of Agriculture, Setsunan University, Associate Professor Tomohiro Segawa of the Sports Promotion Center, and a research group at Kyoto Prefectural University of Medicine investigated the intestinal environment of members of the Setsunan University rugby club. It was found that there are many cases of succinic acid produced by them, and succinic acid has reached the level of patients with colitis.
According to Setsunan University, although the intestinal environment of rugby members is high in succinic acid, which is created by bad bacteria and causes inflammation, there is less butyric acid that suppresses inflammation and regulates immunity than ordinary people, and a quarter is detected. I didn't even do it.
In addition, there were more than twice as many cholinerella bacteria as in the general population, which increased when dietary fiber intake was low.Rugby members consumed only 2-4,000 grams of fiber on a 4,800-12 kcal diet, less than the average intake of 14 grams for the average person.
Butyric acid is produced by butyrate-producing bacteria, but few foods contain butyric acid bacteria.Therefore, in order to increase butyric acid in the intestine, it is necessary to ingest dietary fiber that feeds butyrate-producing bacteria.However, rugby team members thought that protein and carbohydrate intake was important for body building, and as a result, it became clear that dietary fiber intake was insufficient.
One of the subjects, Katsuichi Takashiro, who is currently a member of the Japan Rugby Top League Toshiba Brave Lupus, took 1 grams of dietary fiber a day with supplements and meals for four weeks before graduating from university. However, good bacteria such as bifidobacteria and butyrate-producing bacteria that were not detected before inoculation increased significantly, and succinic acid decreased to one-fifth.While maintaining the energy intake when he belonged to the rugby club, he gained weight (muscle mass), improved bowel movements, and healed acne, which was often seen before, and his physical condition improved dramatically.
The research group believes that ingestion of functional foods alone will greatly improve the intestinal environment, and based on this result, we are currently trying to improve the intestinal environment of rugby members with the cooperation of food companies.Setsunan University will continue its research with the aim of further improving the performance of student athletes by improving their nutrition.
