At the five-meter-deep whale pool in Taipei's Songshan Sports Center, this triathlon wetsuit fitting event hosted by Iron Soul invited a Japanese professional team and coaches for hands-on guidance. The footage captures triathletes trying on custom-tailored professional wetsuits and immediately testing their buoyancy and shoulder mobility in deep water. How exactly do wetsuits enhance water feel, alter swimmers' stroke posture, and improve kicking efficiency? Watch as athletes in the lanes continuously adjust their stroke rhythm and breathing sensation, fully preparing their gear for the upcoming open-water races!
