Nutritional strategies for endurance and ultra-endurance cycling
… is a commonly recommended dietary practice for endurance sporting events lasting >90 minutes. CHOloading effectively maximizes muscle glycogen stores and has been shown to enhance prolonged exercise performance. However, the body’s glycogen stores are limited, therefore a dietary strategy that …

High Levels of Total Energy Expenditure in Ultra-Endurance Athletes: Is There Evidence for Constraint?
… yrs., F = 28) who ranged from being sedentary to ultra-endurance trained runners (0 to 78 mi/wk.) using the doubly labeled water technique and PA and sedentary time using a waist mounted triaxial accelerometer during the same 14-day period. We obtained fasting serum (albumin, cortisol, TNFα, …

The effects of an ultra-endurance event on heart rate variability and cognitive performance during induced stress in Ironman triathletes
The effects of long-term participation in ultra-endurance exercise on the cardiovascular system have recently been the subject of much interest. It is well known that HRV, a marker of autonomic activity, is enhanced with long-term aerobic exercise training. However, after acute exercise, HRV is …

The association of the AVPR2 gene with serum sodium and water imbalances during an Ironman Triathlon
It is well documented that participation 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 …

Markers of immunosenescence and oxidative stress in healthy adults
… was more pronounced and prolonged, following ultra-endurance exercise. Studies also showed that infection with a highly prevalent and asymptomatic herpes virus, Cytomegalovirus (CMV), shapes our immune biology in two significant ways. First, CMV amplified the magnitude and kinetics of …

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 …

The influence of low physical activity levels versus extreme physical activity levels on brain structure and working memory
… of low physical activity and participation in ultra-endurance events are increasing. However, the impact of extreme physical activity levels on brain matter volume and working memory is not well understood. This thesis thus investigated the relationship between different levels of MVPA, brain …

A Comprehensive Analysis of the Sex Difference with Increasing Age in 100-Mile Ultramarathon Performance
Sex differences in endurance performance are often reported to range between 10% and 12%, however it remains unclear whether this disparity applies to ultramarathon events. Preliminary findings suggest that sex-based performance differences in ultramarathons are influenced by age, the participation …
