Comparison half marathon to marathon

Half-marathoners are younger and slower than marathoners The performance of marathon runners is well examined, while there is little for half marathon.We have analyzed over 500,000 half marathon and marathon runners, which were between 2000 and 2014 in Switzerland at the start. It showed up the significantly more athletes about half marathon than run over Marathon.If you compare all women against all men, the women ran faster both in the half marathon like in the marathon. The average age was for both routes and both sexes by 40 years.However, the runners in the marathon were older than the runners in the half marathon.

Mortality for athletes

All-cause and disease-specific mortality among male, former elite athletes: an average 50-year follow-up A recent study examined the survival of athletes compared to non-athletes over the course of 50 years. The average life expectancy of the athletes was on average by 5-6 years higher than non-athletes. The athletes died on average at 79 years while the non-sportsman did not come over about 73 years.The work can be found under https://pubmed.ncbi.nlm.nih.gov/25183628/

Sodium supply during ultramarathon

Sodium Intake During an Ultramarathon Does Not Prevent Muscle Cramping, Dehydration, Hyponatremia, or Nausea. Generally, ultra raptor think that a supply of minerals like sodium is important to avoid problems such as muscle cramps, dehydration and hyponatemia. An American group examined at a 100 miles barrel whether there is a connection between sodium supply and the problems mentioned.In the case of a run with temperatures to almost 40 degrees, together with laboratory values were also completed questionnaires.

The problem of nausea during an ultramarathon

Nausea is associated with endotoxemia during a 161-km ultramarathon. During an ultramarathon, many runners suffer from digestive problems such as nausea. An American group examined possible relationships between digestive problems and various laboratory parameters. Amazingly, it was found that parameters of endotoxemia (= poisoning caused by the decay of bacteria are associated with digestive problems with digestion problems with the release of endotoxins. This new aspect can be found under https://pubmed.ncbi.nlm.nih.gov/26707127/

Running and immune system

Salivary Immuno Factors, Cortisol and Testosterone Responses in Athletes of a Competitive 5,000 m Race. During a physical stress, there is a passable immunosuppression, there is an interaction between endocrine and immunological systems. Chinese researchers have examined in male and female 5'000 m runners what happens with specific laboratory parameters of the endocrine and immunological system. Iga in saliva was in the women as during the run higher than in men.The testosterone took off in men after the barrel, while women do not.

Kidney function in Ultralauf

Does Acute Kidney Injury From an Ultramarathon Increase the Risk for Greater Subsequent Injury? An American group has studied 627 runners in a 100-mile runway whether damage to renal function increases by an ultra-rose risk for further kidney problems.

It showed that a slight kidney damage in ultra skiers is customary but this is not a problem for further runs. The very important result can be found under https://pubmed.ncbi.nlm.nih.gov/26657822/

Sodium household during a marathon

Sweat sodium loss influences serum sodium concentration in a marathon A Spanish group examined, which has the loss of sodium with the welding for an influence on the sodium concentration in the blood. 51 runners were divided into different groups based on their welding.It was a connection between sodium loss in the welding and sodium in the blood.

However, the runners with the largest sodium loss in the sweat did not develop hyponatemia. All numbers can be found under https://pubmed.ncbi.nlm.nih.gov/26661748/

Sex differences in ultra skills

Sex Differences in Participation, Performance and the Age of Ultramarathon Runners An American group has studied how the difference between men and women in ultra-based developed in terms of ranking and participation.They examined 20 races from 45 to 160 km. The men were faster than the women.The difference was the deepest over 100 km and the greatest over 45-50 km.The fastest men were younger than the fastest women. The difference between the sexes rose with ranking, was the deepest in the winners and higher at the runners in the 10th place.

What happens for 24 hours cross-country skiing?

Clinical and Laboratory Responses of Cross-Country Skiing for a 24-H World Record: Case Report A Finnish group has studied what happens in a ski runner who is traveling for 24 hours at temperatures from -24 ° C to -5 ° C. The athlete reached 406 km and after the burden there was a significant increase in myoglobin, CK, probnp but no increase in troponin T or Tropinin I. After the load, the size of the left ventricle decreased by around 5%.It also came to an increase of parameters of liver and renal function as well as CRP and leukocytes.
