Dolphins coach on alert for ISL burnout as pro league shakes up sport

Dolphins head coach Jacco Verhaeren will sit down with the nation's best coaches and athletes in coming months as officials try to forecast the impact of the new International Swimming League on preparations for the Tokyo Olympics.

The sport stands on the verge of significant disruption when the professional ISL springs into life later in the year. It will feature a number of star Australians including Kyle Chalmers and Cate Campbell, competing for the various franchises in Europe and the United States.

The potential financial gain and added race experience has been widely welcomed in the sport despite governing body FINA being dragged kicking and screaming into the new era, but Verhaeren is just one senior figure wary of the impact on the Olympic schedule.

He will have both eyes firmly on the national titles, beginning in Adelaide on Sunday, but will quickly begin a tour around the elite training centres to plot the path to Tokyo and decipher the impact of the ISL, which has its finals in Las Vegas just days before Christmas.
