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/

‘Orca’ in cold training In May, the German Extreme Swimmer wants to cross the Lake Constance of Length.To this season, the water will be relatively cool, so, Orca ‘is already preparing in cold water, see https://www.youtube.com/watch?v=2b3-ibmsjcw

How Tilen Ultralaufen?

Demographic Characteristics of 161-km Ultramarathon Runners. An American group has examined what ultra-riders are for people. Mostly, the married men are 45 years with higher education, but more details below https://pubmed.ncbi.nlm.nih.gov/22242737/

Hyponatriämie bei Mountainbikern

No case of exercise-associated hyponatremia in male ultra-endurance mountain bikers in the ‘swiss bike masters’. The load-associated hyponatremia is observed relatively often in endurance athletes. Today’s opinion is that rather slow athletes drink relatively too much and thereby comes to a dilution. On the ‘Swiss Bike Masters’ we found surprisingly that the fastest drivers drank the most and that still no mountain biker developed a hyponatremia. The results of the study can be found under https://pubmed.ncbi.nlm.nih.gov/22229504/
