The National Federation of State High School Associations streamlined rules in regard to dolphin kicks in the breaststroke for high school swimming.
The NFHS approved rule changes at its meeting in March, clarifying on paper what has been in practice in the pool for years.
High school swimmers are allowed to use a butterfly kick (dolphin kick) at the start or a turn before moving into a breaststroke kick.
Also, competitors will no longer be asked to step off the starting blocks if an illegal suit is spotted. They will finish the race and then be disqualified at the end of the heat.
