Core Temperature during Cold-Water Triathlon Swimming

Core temperature and hydration status during an Ironman triathlon.

BACKGROUND Numerous laboratory based studies have documented that aggressive hydration strategies (approximately 1-2 litres/h) are required to minimise a rise in core temperature and minimise the deleterious effects of hyperthermia on performance. However, field data on the relations between hydration level, core body temperature, and performance are rare. OBJECTIVE To measure core temperatur...

Evaluation of two cold thermoregulatory models for prediction of core temperature during exercise in cold water.

Cold thermoregulatory models (CTM) have primarily been developed to predict core temperature (T(core)) responses during sedentary immersion. Few studies have examined their efficacy to predict T(core) during exercise cold exposure. The purpose of this study was to compare observed T(core) responses during exercise in cold water with the predicted T(core) from a three-cylinder (3-CTM) and a six-...

Triathlon: swimming for winning

Olbrecht J. Triathlon: swimming for winning. J. Hum. Sport Exerc. Vol. 6, No. 2, pp. 233-246, 2011. Swimming performance in triathlon gradually gets of overriding importance in view of the final positioning in a race. It is important to end up swimming in the leading group(s) and to consider the impact of the swim stage on the 2 remaining sports disciplines in order to outbalance the athlete’s ...

Optimization of Swimming Performance in Triathlon

Despite the variation in swimming performance of elite triathletes is generally small, longitudinal observations of swimming performance in the top 20 elite triathletes in the world compared to that of the remaining field indicate that swimming performance is crucial at Olympic distance triathlon at elite level (Bentley et al., 2008). Therefore, researches that addresses optimization of swim pe...
