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/

Olympic participants live longer

Mortality in Female and Male French Olympians: A 1948-2013 Cohort Study Often one goes out of the intense physical stress should be harmful to harm. A French group has retrolled French participants in winter and summer Olympiads 1948-2010 with regard to their survival.

The mortality was 51% for women and 49% deeper in the men compared to the French population. Similar to the general population, the athletes also die of tumors and cardiovascular diseases. The whole compilation can be found under https://pubmed.ncbi.nlm.nih.gov/25813868/

Oldest master swimmer died of the world

Jaring Timmerman, The Oldest Masters Swimmer, Passes Away At 105 Already in November 2014, the oldest master’s swimmer in the world died. At the high age of 105, the Canadian Jaring Timmerman died in Winnipeg, Manitoba.He held 4 world records in the age group M100-104 and for him the age group M105-109 was created. Surprisingly, he started swimming only with 78, and yet he sat down 23 Canadian state records (7 in category M85-89, 4 in category M90-64, 8 in category M95-99 and 4 in category M100-104).

New world record at 100 years

100-year-old Japanese woman sets her own 1,500-metre freestyle swim record Mostly interested in sport only the absolute world records, so regardless of the age group. In our current world, however, people are getting older and for many sports are guided retirement records.An extreme retirement record was recently set up.

The 100-year-old Japanese Mieko Nagaoka launched a world record in the category F100 over 1500 m freestyle. She managed the route in 1 h and 16 min. Two aspects are even more amazing: the lady started swimming only with 80 and then you would like to set up a new retirement recorder in the F105 category.
