Jae-Hyun Yoo, the South Korean coach at the Azraq refugee camp in Jordan, has claimed that self-confidence is key to success in taekwondo.
Yoo coaches alongside Jordanian Asif Sabah at a camp support by the Taekwondo Humanitarian Foundation (THF) development programme.
He has previously volunteered in Rwanda for the WTF's Taekwondo Peace Corps, which deploys instructors to developing nations worldwide.
"In my opinion, the most important element for my students is self-confidence," he said in an interview published on the THF website.
The training, Yoo said, gives the students a "sense of belonging as a team" as well as such beneficial skills as self-defence.
"When I heard about ongoing distresses among refugees in the region, I was concerned about the refugee children and wanted to provide hopes and vision in their lives through taekwondo," he added.
"We wanted to provide various opportunities for them to learn and experience through taekwondo, hoping that through taekwondo they will have hopes and dreams.
"So we made many activities like demonstrations, promotion tests, competitions, marathon races, et cetera.
"They have started to have dreams and to put an effort into achieving their dreams.
"Just looking at the positive changes that took place in my students, made me feel great."
The THF, established by the WTF, aims to teach the sport and related educational programmes to refugees and displaced persons worldwide.
Most of those living in Azraq have fled the conflict in bordering Syria.
The camp was the THF's first full-time and permanent programme.
