Abstract
This research investigated the use of dietary supplement patterns and doping awareness among high-ranked Judoists from two countries. Korean (70 males and 31 females) and Japanese (37 males and 34 females) national Judo team members were divided into two groups (high and low competitive performance levels) according to their international and national rankings. Fifty-nine percent of Korean and 61% of Japanese Judoists consumed dietary supplements. Eighty-eight percent of high and 51% of low competitive performance level Korean Judoists consumed dietary supplements. Sixty-eight percent of high and 57% of low competitive performance level Japanese Judoists consumed dietary supplements. Oriental supplements (34%), vitamins (23%), and protein powder (12%) were most commonly consumed dietary supplements in Korean Judoists. Otherwise, vitamins (45%), protein powder (33%), and minerals (15%) were most commonly consumed dietary supplements in Japanese Judoists. Thirty-eight percent of Judoists from both countries had not received any proper education about anti-doping and 44% of Judoists from both countries had not received about knowledge of anti-doping legislation. There was a significant difference in education about anti-doping between high and low competitive performance levels of Korean Judoists (p < 0.001). Korean Judoists received significantly less anti-doping education than Japanese Judoists (p < 0.001). The associations for anti-doping education and knowledge of anti-doping legislation with the use of dietary supplements were 3.46 (95% CI = 1.31-9.12) and 1.63 (95% CI = 0.71-3.76), respectively. Our findings showed Judoists' use of dietary supplement from both countries was increased followed by experiencing anti-doping education.
