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.
