Abstract | Introduction: To date, no cumulative evidence has been collected on the solar ultraviolet exposure received by triathlon competitors assessing the cumulative and discrete exposure risks measured during the swim, bicycle and running legs of competitive Australian Ironman events. This sport has previously been highlighted as having potential for very high cumulative exposure given the extended requirement to be outdoors, often during peak UV exposure periods. Methods: Miniaturized polysulphone film dosimeters manufactured at the University of Southern Queensland were attached to the posterior of a swimming cap, vertex of a bicycle helmet, and vertex of a sports cap during the swim, bicycle and running legs of competitive triathlon events held in Australia during the summer and early autumn of 2017 and 2018. Dosimeters were calibrated to ambient seasonal conditions. Exposures are presented as absolute erythemally effective values [J m-2] and with respect to the available ambient UV. Results were also collected during separate swimming, bicycle and running training schedules of selected athletes. Results: Preliminary results indicate the initial swimming leg of competition resulted in the highest personal exposures, followed by the bicycle and running legs of triathlon events. Typical exposures ranged from between 20 to 50% of the available erythemally effective ambient. Conclusion: The swimming stage of competitive triathlon events resulted in very high cumulative erythemally effective exposure despite this stage often being the shortest in terms of event duration. A possible explanation for this may be due to reflected solar ultraviolet from ocean and river surfaces highlighting the need for triathletes to cover up using full length swim suits to minimize exposure risk. Variable exposures during the bicycle and running stages of triathlon events may be due to greater variation in surface albedo and cover from surrounding tree canopies and structures encountered along course routes. |
