Description

The purpose of this study was to examine the effect of ingestion of the dietary supplements Rikinin and protein on the physical characteristics of university athletes. The subjects belonged to the Osaka International University Men's Soccer Club. The 35 subjects who obtained consent were randomly assigned to 3 groups （protein and Rikinin group; PR group, protein group; P group, Rikinin group; R group below）, and measured before and after ingestion. There were 8 PR groups, 12 P groups, and 9 R groups. The right and left arm muscle mass was significantly higher only in the PR groups（ p＜0.05）. In the right leg muscle mass, the PR groups and the P groups had significantly higher values, and in the left leg muscle mass, the PR groups and the P groups had significantly higher values. Only the R groups showed a significantly high value in the arrival time of the Wingate test peak. This suggests that the γ-oryzanol contained in Rikinin affected anaerobic endurance, and also that further detailed study is necessary.
