The "Fair" Triathlon: Equating Standard Deviations Using Non-Linear Bayesian Models
<p>The Ironman triathlon was created in 1978 by combining events with the longest distances for races then contested in Hawaii in swimming, cycling, and running. The Half Ironman triathlon was formed using half the distances of each of the events in the Ironman. The Olympic distance triathlon was …

The use of near-infrared spectroscopy (NIRS) in the physiological assessment of sprint triathlon.
Sprint triathlon is a high intensity endurance discipline with ever-growing participation rates, but the sport currently remains under researched. The requirement to complete swim, cycle and run stages consecutively places unique physiological demands upon triathletes that are superior to that of …

Left ventricular function after ultra-distance triathlon : response is dependent on the cardiac loading conditions
The purpose of this thesis is to establish if there is any evidence to support the hypothesis that altered ventricular loading conditions after the cessation of exercise may cause "cardiac fatigue". The studies that have shown post-exercise "cardiac fatigue" have not controlled for either preload …

The association of the AVPR2 gene with serum sodium and water imbalances during an Ironman Triathlon
… in ultra-endurance events such as the Ironman Triathlon, can be associated with the development of post-race water and sodium imbalances in athletes. Variants within genes that encode for proteins that regulate thirst have been shown to be associated with weight changes during participation in …

The impact of training load on injury and illness in a 12-week training period for an iron-distance triathlon
BACKGROUND Given that triathlon is recognised as an official sport by the International Olympic Committee (IOC), a focus on injury prevention strategies for participation in triathlon is necessary. A model for injury prevention programme development that is used currently is the Translating …

Prediction of triathon performance from ventilatory threshold measurements
The purpose of this study was to predict Ironman Triathlon (2.4 mile swim, 112 mile cycle, 26.2 mile run) performance times from ventilatory threshold (TVENT) measurements of swimming, cycling, and running. Ten trained triathletes (mean age = 29.7yrs., ht = 179.8cm, wt = 76.8kg, bodyfat = 11.4%) …

Clinical and immunological factors associated with post-race upper respiratory tract symptoms (URTS) in Ironman triathletes
Ultra-endurance events, in particular Ironman Triathlons, are physically very demanding for the competitors. There is a large body of evidence showing the Upper Respitory Tract Symptoms (URTS) are very common in athletes in the 2-week period after such an event. However, there is no definitive …

Gastrointestinal tract (GIT) symptons in Ironman triathletes : a study relating GIT symptons to changes in splanchnic blood flow
… athletes such as those competing in the Ironman Triathlon. Although a number of risk factors and the pathophysiological mechanisms for the development of GIT symptoms during exercise have been proposed, scientific evidence in support of these factors and mechanisms is limited. Altered blood flow …
