No weight loss for long-distance swimming

Body composition and hydration status changes in male and female open-water swimmers during an ultra-endurance event. In general, the opinion is represented that subcutaneous fat is reduced with swimming.Since a large muscle mass is moved and in the mostly cool water due to the cold additional fat should be consumed, it must lead to a degradation of fat. We studied 20 men and 11 women at the marathon swimming in Zurich, which happens after around 27 km swimming with regard to the fatty tissue. While the men accepted weight and muscle mass, nothing happened to the women. The results in detail under https://pubmed.ncbi.nlm.nih.gov/22554315/

Energy deficit at 24 hours cycling

High energy deficit in an ultraendurance athlete in a 24-hour ultracycling race. We have determined the energy balance with a cyclist on a 24-hour wheel race.During the

Runs, he consumed 15'533 kcal and led 5'571 kcal, resulting in a negative balance of 9'915 kcal. The detailed balance sheet is available under https://pubmed.ncbi.nlm.nih.gov/22481841/

Too much drink makes thick feet

An increased fluid intake leads to feet swelling in 100-km ultra-marathoners - an observational field study. The phenomenon that long-distance swelling developed has already been investigated and described in seventies through Williams. The researchers have demonstrated an increase in extracellular water at that time, but could not explain the cause.The edema were considered as a possible cause of lung edema in a large amount.

We now have a clear context of 76 ultra skiers to show a clear context between fluid supply and volume of feet: the larger the supply of fluid, the sooner it comes to a swelling of the feet. The study is accessible under https://pubmed.ncbi.nlm.nih.gov/22472466/

Influence of gender and age at Powerman Zofingen

Gender difference and age-related changes in performance at the long-distance duathlon We have investigated the influence of sex and age for the performance at the Powerman Zofingen ‘for the years 2002-2011. In these 10 years, no performance improvement in the TOP10 showed up.Women was average 16% slower than the men.

The fastest times were achieved between 25 and 39 years. All details can be found under https://pubmed.ncbi.nlm.nih.gov/22450258/

Determination of muscle and fat mass

A comparison of fat mass and skeletal muscle mass estimation in male ultra-endurance athletes using bioelectrical impedance analysis and different anthropometric methods. For the determination of muscle and fat mass, there are very elaborate methods such as MRI, Dexa or underwater weighing. Ann is very simple and practicable methods such as the determination of the skin fold thickness and bioelectric impedance analysis (BIA). We compared the practically simple methods of skin fold thickness and Bia with more than 200 men.

What happens at a 10-fold Ironman in the liquid balance?

Effect of a multistage ultraendurance triathlon on aldosterone, vasopressin, extracellular water and urine electrolytes. Each athlete in the ultra-area has already seen in itself or on colleagues that hands and / or feet swell and sometimes the face is blazing. In analogy to the stress-associated hyponatremia, where the hormone could play vasopressin, we have determined hormones and electrolytes in urine at 10 times Ironman of Mexico 2009 and determined the extracellular water. We assume that there is a connection between the increase in extracellular water and the change in the hormones of the regulation of the water and electrolyte household.

Anthropometry and Split Performance in Male Ironman Triathletes

Body construction and competition times at Ironman Triathlen On the basis of a larger collective of Ironman triathletes, we examined which characteristics of body construction are important for which section in an Ironman.

A deep body weight, a deep body mass index, and a deep body fat correlated both with the total time as with the marathon time. In addition, the surges of the upper arm were associated with the marathon time as the thigh. The details can be found under https://pubmed.ncbi.nlm.nih.gov/22375214/

Relative improvements in endurance performance with age- Ironman Hawaii

Performance improvement of master triathletes at Ironman Hawaii From 1986-2010, the number of master triathlets (over 40 years old) has increased at the Ironman Hawaii, while the number of triathlets decreased younger than 40 years.Male triathlets over 44 years and female athletes over 40 years could significantly improve their performance over the course of these 25 years.

In the age groups 40-44 years to 55-59 years, the difference of performance between the sexes decreased significantly. Further details under https://pubmed.ncbi.nlm.nih.gov/22367579/
