Keen kayakers Luke O’Garey and Julie Sladden will take part in two separate kayak events in coming months.

O’Garey will take on Hawaii’s Molokai World Championships in July, while Sladden has challenged herself to a 52-kilometre kayak up the Tamar River for her breast cancer fundraiser, Paddle4Pink, next month.

The pair have called on University of Tasmania clinical exercise physiologist Stephen Stone to help take their cardiovascular strength to the next level in preparation for the events.

Mr Stone yesterday monitored the kayakers paddling at various speeds over four-minute intervals to determine at which point they reached their lactate thresholds.

In reaching this threshold, the pair will now have a better understanding of how to ramp up their training in future in order to reach that threshold regularly and increase their fitness levels.

‘‘When the athlete is aware of their threshold and they work out a pace they can sustain without going over the red line, they avoid reaching the point of fatigue too early,’’ Mr Stone said.

Mr Stone said it was rare for this kind of high-intensity testing to be carried out on water and hoped their findings would uncover more about the benefit of reaching the lactate threshold while training for water events.

UTAS is one of few bodies to have carried out this experiment, along with Tasmanian-based company, Next Level Kayaking.

O’Garey said the results would be highly beneficial to his training.

‘‘In order to take your training to the next level, you need specific data about how to maximise your efforts,’’ he said.
