Liver and muscle damage at 100 km running

Damage to Liver and Skeletal Muscles in Marathon Runners During a 100 km Run With Regard to Age and Running Speed. A Polish group examined at a 100 km pathway whether there is a damage to liver and muscle, whether any damage depends on age or running speed and whether it would be possible in this case to determine the optimal running speed to have no damage. It showed that it came to an increase in liver values, with this increase in the recreational phase still went on.There was also an increase in LDH, CK and CRP.The biggest difference in the rise of these parameters was after 75 km and after 24 hours a recreational phase.

From the Ironman to the Ultra Triathlet

What predicts performance in ultra-triathlon races? – a comparison between Ironman distance triathlon and ultra-triathlon In an overview, we have relevant to the variables that are important for an Ironman triathletes as well as for an ultra-triathletes. As a rule, a triathlete will start over the short distances to the Ironman before changing to the ultra-triathlon.It clearly showed that Ironman triathlets and ultra-triathlets differ. Although both benefit from a deep body fat for a quick competition time, the Ironman Triathlen is the speed in training in the foreground during the ultra-triathlet the high volume dominates.

Temperature of the liquid in the heat

The role of fluid temperature and form on endurance performance in the heat If athletes burden in the heat, there is an increase in body core temperature. This can affect unhealthy and restrict performance.The supply of cool drinks can reduce the body core temperature before loading, but not during the load.

The temperature of a drink does not seem to have an influence on the stomach emptying and absorption in the intestine. The supply of a mixture of water and ice (ICE Slurry) seems to be very efficient to avoid an excessive increase in body core temperature and improve endurance performance in the heat.

Hiker dies at hyponatremia

Hiker Fatality From Severe Hyponatremia in Grand Canyon National Park The stress-associated hyponatremia in endurance athletes is well-known and well examined. An American group describes the case of a woman who wandered at the Grand Canyon National Park for 5 hours.During this hike, she should have drunk a lot of water.After she collapsed she was brought to the nearest hospital and a hypervolemic hyponatremia with encephalopathy was diagnosed.Despite all measures, it died within 24 hours on a brain edema.

Glucose and fructose under stress

Saccharide Composition of Carbohydrates Consumed during an Ultra-endurance Triathlon

It is generally known that the supply of a mixture of glucose and fructose during physical stress increases carbohydrate oxidation and reduces gastrointestinal problems. With a 70.3 triathlon, the athletes consumed different products and drinks.The ratio of glucose to fructose was on average 2.9: 1.If more than 50 g of carbohydrates were supplied per hour, it was more likely to digestify problems. The study can be found under https://pubmed.ncbi.nlm.nih.gov/25941980/

Milk and muscle

The effect of milk on the attenuation of exercise-induced muscle damage in males and females$ The use of milk can influence the development of muscle cats. An Irish group has studied the influence of milk compared to carbohydrates after a muscular burden on notes for low muscular damage.

They could show that 500 ml of milk leads to a lower expression of muscle cats after a physical stress. The very interesting work can be found under https://pubmed.ncbi.nlm.nih.gov/25673557/

At what age is the best performance over 100 km?

Performance and Age of the Fastest Female and Male 100-km Ultramarathoners Worldwide From 1960 to 2012 We have all existing competition results for 100 km from 1960 to 2012 examined with the idea to find the age of the best performance. Overall, 18,998 women and 129,019 men were identified by the total of 148'017 final times.If you take the top 10 a year, you come to the end that men like women became faster and the women approached men.

Formulas for the calculation of competition times in Marathon and 100km

Effects of training and anthropometric factors on marathon and 100 km ultramarathon race performance As a rule, a later ultra-rider starts with a marathon.We compared characteristics of marathon runners with characteristics of 100km runners to find differences in physique (about body fat) and training (approximately running speed and volume). It was about to find the relevant variables and to refine the previous formulas even further to estimate with simple variables for the competition time for marathon and 100km.

Muscle damage at Ultramarathon

Mountain Ultra-Marathon Causes Sarcomere Disruptions of Slow Fibres For longer running loads, there is a damage to the muscles. A Spanish group suggests whether the slow or more the fast fibers are harmed in an ultramarathon.

The proof and course of certain parameters of the muscle damage concluded that the slow fibers are more likely to harm. You can read the work under https://pubmed.ncbi.nlm.nih.gov/25848839/
