Several records were broken on the first day of the Division One inter-school swimming competition held at Kowloon Park Swimming Pool last Thursday.
Belilios Public School's Jasmine Wong Yuk-yan, 16, broke the A grade girls' record for the 50m butterfly, coming first with a time of 28.02 seconds.
She told Young Post she focused most on her underwater kick and touching the wall.
She said taking part in this week's National Youth Games would help her prepare well for the finals of the inter-school swimming competition which will be held on October 28 at Kowloon Park.
Jasmine thinks Diocesan Girls' School's Tam Hoi-lam, 17, could pose a serious threat.
"Hoi-lam is really powerful and experienced. She took part in the 2014 Asian Game in Incheon, South Korea. It will be really tough with her in the final," said Jasmine.
Hoi-lam, who came second in the women's 4x100m medley relay at the 2014 Asian Games, ranked first in the A Grade 100m freestyle. Hoi-lam said she has been adjusting her tactics in the 50m butterfly, focusing more on the synchronisation between her arms and legs.
Vincent Suen Wai-cheong, 18, from Wah Yan College, Kowloon, and 16-year-old Martin Lam Ho-yin from La Salle College faced off in the A Grade 50m freestyle. Vincent won the heats with a record-breaking time of 23.97 seconds, with Martin coming second. But the final will determine the ultimate winner, and Martin's coach, Albert Hau, said he was happy with his student's performance.
"Martin hasn't peaked yet. For the next two weeks, he can focus more on turning and his underwater technique. His endurance and pacing are strong," said Hau.
Both Vincent and Martin will face tough competition in the A Grade 100m freestyle from 18-year-old Miles Jing Williams. The West Island School (WIS) student came first in the heats and set a new record of 51.97 seconds. Richard Lant, head of sports at WIS, said Miles is both physically and mentally well prepared.
"Perhaps in the final he can improve his personal best," he said.
Both St Joseph College's Wong Ho-kiu and Diocesan Boys' School's Ng Yan-kin also set new records in the A Grade 100m breaststroke. Ho-kiu, 17, came first with a time of 1:05.45, while Yan-kin, who came second, clocked 1:05.97, beating the old record of 1:06.19.
