Body core temperature in the preparation for the sleeve channel

The effect of cold water endurance swimming on core temperature in aspiring English Channel swimmers An Australian group has examined the course of the body core temperature in floats, which have completed a preparatory swimming over 6 hours at a water temperature of around 15-16 ° C. It showed that the body core temperature absorb, regardless of the physique of the swimmers.

Older floats tended to a hypothermia as well as swimmers with a deeper impact frequency while swimming. This work can be found under https://pubmed.ncbi.nlm.nih.gov/26835005/

Masterathlets in the freestyle swimming

Performance trends in master freestyle swimmers aged 25-89 years at the FINA World Championships from 1986 to 2014 The performance of elite schemes in freistic swimming is well examined. On the other hand, it is not known as the performance of age-class athletes in the freestyle swimming has developed since 1986.Since this year, there is official World Championships for Masterathlen who will start without preliminary and finals. Thus, one can examine both the development of participation as well as the performance for these athletes.We have thus examined how participation and performance have developed for more than 65,000 athletes in the age groups 25-29 to 85-89 years. It showed that participation in the athletes older than 40 years increased.For men like women showed that the performance over all the freestyle routes in all ages improved.In the age groups 25-29 to 75-79 years, men were faster than the women, but not in age groups 80-84 to 85-89 years.

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.

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/
