Yusei Imaizumi Breaks World Junior Record in Short Course 100m Breaststroke: Opportunity for Japanese Golden Generation

In swimming sports, Yusei Imaizumi broke the world junior record in short course 100m breaststroke with a time of 56.35 seconds at the domestic Japanese tournament. This is a new record for the Japanese junior generation, competing with Shin Ohashi. The analysis shows a strategy of swimming the front half faster, but attention is needed on converting from short to long course. Technical analysis shows Yusei Imaizumi swims the front half faster than Shin Ohashi, maintaining pace in the back half. This record was set at a prefectural high school tournament, has high value but needs to be checked at higher level. Data shows Japan is leading the young generation in breaststroke. Need to follow up to see if there is ability to convert to long course.
