Abstract
This study examined how differing triathlon durations effect weight, serum sodium concentration, and hematological levels, and investigated relationships between these variables and finishing time as well as between body weight changes and serum sodium following Ironman distance triathlons (IDT) and Olympic distance triathlons (ODT). All eight athletes successfully completed ODT and IOT. We found that the mean body weight decreased following both IDT and ODT and that serum sodium was significantly (p<0.05) increased immediately after IDT, RBC, Hb, Hct, and MCH were significantly (p<0.05) increased immediately after IDT. Hct was significantly (p<0.05) decreased immediately after ODT. MCHC was significantly (p<0.01) increased immediate1y after ODT. In IDT, the percentage of change in body weight correlated to the percentage of change in serum sodium concentrations (r=0.75, p=0.05). In conclusion, our srudy showed that serum sodium concentraion increased in IDT and maintained in ODT, despite significant body weight loss during the races. The percentage of change in body weight was related to serum sodium concentration but unrelated to performance in the triathlon. The changes of RBC, Hb, and Hct values from two different length triathlons were depending on race distance.
