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.

Why are the Kenyans so fast?

Analysis of the Kenyan distance-running phenomenon General is known that the Kenyans are the best runners on the longer routes to marathon. An African group has now analyzed the results of runs from 800m to Marathon from 1964 to 2013. Depending on the running distance dominate different Kenyan ethnic groups.In the marathon the Nandi are best.On the train, on the other hand, the Maasais, Marakwets and Pokots.

Like the Nandi, runners of the ethnic groups of Keyos, Kikuyus, KIPSigis, Sabaots and Tugens are better in the marathon than on the train. This very interesting work can be found under https://pubmed.ncbi.nlm.nih.gov/25115138/

Pacing over 100 km

Pacing strategy in male elite and age group 100 km ultra-marathoners The pacing in UltraLauf for 100 km and 100 miles for the top runners already examined. On the other hand, we do not know how the runners behave in the age groups.At 100 km run in Biel there are 3 places where the intermediate time of the runners is measured.We have now investigated whether there are differences in the age groups assuming that the older runners be slowed over the 100 km faster than the younger runners. From 2000 to 2009, the timekeep was always the same and it was first shown that the runners in the first segments were getting slower, but could turn up again on the last segment.If you look at the individual age groups, the running speed for all age group athletes sank in the first two segments.On the last segment, however, all runners could keep the speed while the runners were faster in the age group 40-44 years faster.Amazing is that the recent runners (18-24 years) showed the largest performance drop across the 100 km.

Dehydration for long-distance wheel driving

Hydration status affects mood state and pain sensation during ultra-endurance cycling In laboratory studies, it was postulated that dehydration influences the mood situation. In a field study with 119 cyclists, which drove over 161 km, it was investigated whether there could be a connection between dehydration and mood.

It clearly showed that dehydrated drivers suffered from more fatigue and pain than non-dehydrated drivers. The interesting work can be found under https://pubmed.ncbi.nlm.nih.gov/25793570/

Unexpected intoxication

Not more than 1/16 of a coffee spoon, otherwise it will be dangerous! In a case report in ‘Swiss Medical Forum’, a 36-year-old man described which has taken a caffeine-containing product.

The doctors came to the conclusion that he has suffered a heavy caffeine monointoxication. In the extreme dining area - if the competitions go over days and nights - athletes and caregivers want to distribute the fatigue with caffeine. It is very worth reading the article and see what can happen if you get too much caffeine, see https://www.medicalforum.ch/docs/smf/2015/12/en/smf-02223.pdf

Performance development in older athletes

Greater progression of athletic performance in older Masters athletes In recent years, fewer world records have been achieved in sports. On the other hand, the number of older athletes increased and their achievements were getting better.An American group examined the performance development over 100 m running, 400 m running and 100 m swimming from 1975 to 2013 for age-class athletes on world class levels.Over 100 m walk showed no improvement in the recent (fastest) group, but the times in the older age groups were getting better.

Hyponatriämie bei River Rafting

Three Cases of Severe Hyponatremia During a River Run in Grand Canyon National Park An American group has described three cases of hyponatremia at River Rafting. Three women have fed too much liquid because they meant to suffer dehydration in the longer stress.All three women had to be hospitalized and intensive care. In contrast to the stress-associated hyponatremia, there were no physical stresses here and yet there was a hyponatremia.
