Hyponatremia at swimmers

Exercise-Associated Hyponatremic Encephalopathy in an Endurance Open Water Swimmer In general, it is known that its too high fluid supply during physical load leads to a dilution hyponatremia, in plain text, the sodium decreases in the blood. If you drink too much - because it is hot and / or because it is said to drink a lot to do not dehydrate - can have the serious consequences.An Australian research group has a fall of a long-distance swimmer at a 20 km swimming in the ocean. The too high fluid intake led to a stress-associated hyponatrominic encephalopathy with change in the state of consciousness.The sodium was 119 mmol / l at this time. She had to be monitored intensive care in the hospital, but then could go home healthy.

Sex difference in swimming with increasing age

Sex differences in elite swimming with advanced age are less than marathon running. An American group has studied whether the difference between men and women increasingly increasingly increases as at marathon.They examined the ranks 1-10 in the age groups 25-89 years. Men were faster than women in freestyle (12.4 ± 4.2%), back (12.8 ± 3.0%), and breast swimming (14.5 ± 3.2%), while the difference in the dolphin (16.7 ± 5.5%) was greatest. The difference in the swimming speed took as part of the top strands for freestyle, breast swimming and dolphin for all ages and routes.

NURMI-Study

Start der NUMRI-Studie in Phase II After only 4 months since the start of the Nurmi-Study, over 2,120 participants are at the start of the Nurmi main study with STEP 2. All phases (STEP 1 to STEP 3) run until 31 December 2015 and can be “refrained” up to and including December 31, 2015!Therefore, we cordially invite all runners from half marathon distance (every level of performance) to participate in the most important study for the running movement to accomplish something big together. All information about the Nurmi Main Study with STEP 2 and STEP 3 can be found on the Nurmi website under https://www.nurmstudy.com/abraufzeit

Die eisterile

World record over the ice mile In the so-called extreme area, there are almost no limits.

A new trend is the competitive swimming in ice-cold water. The ice mile (1,609 meters) was introduced in 2009 through the International Ice Swimming Association (IISA).To date, 138 successful experiments were counted, of which 28 were by women.The times can be found under https://internationaliceswimming.com/iisa-ice-swim-records/ Recently, the German top swimmer Christoph Wandratsch has set up a new world record in 21:38 minutes.He was a few seconds faster than James Bridges, who had swamp the same distance last year in England in 21:43 minutes.

Do the women bring the men?

Performance differences between sexes in 50-mile to 3,100-mile ultramarathons In the context of individual observations in recent years and decades, several journalists and also scientists assumed that the women are sometime in the long-distance course at some point the men in and overtake. To find and see such individual cases whether this observation effectively applied we have analyzed all runs over 50 miles, 100 miles, 200 miles, 1'000 miles and 3'100 miles from the years 1971-2012. When taking the times of the fastest men and women about these routes, the men were over 50 miles (17.5%), 100 miles (17.4%), 200 miles (9.7%), 1'000 miles (9.7%), 1'000 miles (9.7%), 1'000 miles (9.7%), 1'000 miles (9.7%), 1'000 miles (9.7%), 1'000 miles (9.7%), 1'000 miles (9.7%),) And 3'100 miles (18.6%) faster.If you take the 10 fastest men and women, the men were over 50 miles (17.1 ± 1.9%), 100 miles (19.2 ± 1.5%) and 1'000 miles (16.7 ± 1.6%) faster than the women.For all examined routes, no correlation could be found between gender difference and running speed.If you take the fastest times per calendar year, the difference between the sexes over 50 miles from 14.6% took 8.9%. Over 100 miles, the difference remained constant at 18.0% and over 3100 miles he rose from 12.5% to 16.9%.If you take the difference between the 10 fastest runners per year, the difference over 50 miles of 31.6 ± 3.6% decreased to 8.9 ± 1.8%. Over 100 miles, he decreased from 26.0 ± 4.4% to 24.7 ± 0.9%.The bottom line was 17-20% faster than the women.

Younger and older 100 km runners

Do non-elite older runners slow down more than younger runners in a 100 km ultra-marathon? We asked ourselves the question of whether there is a difference in the running point between younger and older 100 km runners. We assumed that the older runners were increasingly slower over the 100 km.For this we took the maturities of the 10 fastest men from 2000 to 2009 on 100 km run in Biel and looked if there is a difference over the 100 km in the age groups. It showed that the running speed in runners in the age group was 18-24 years deeper than the running speed of the runners of the other age groups.And it showed that the running speed was not decreased over all age groups with increasing age.

Liquid supply under load

Self-report Versus Direct-Measurement for Assessment of Fluid Intake During a 70.3-mile Triathlon An American group has studied how exactly triathlets can estimate their supply of fluid on the running track of half a Ironman triathlon. Compared with a precisely measured intake, the self-assessment was not bad, with certain individuals clearly laying down. The work can be found under https://pubmed.ncbi.nlm.nih.gov/25561580/

Pacing im Triathlon

Pacing strategies during the swim, cycle and run disciplines of sprint, Olympic and half-Ironman triathlons An Australian group has studied the pacing behavior of triathlets via Sprint, Olympic Distance and Halber Ironman.8 male triathlets were analyzed during swimming, cycling and running.

The speed remained constant at all routes. When cycling, the pacing was not uniform.When running, the triathlets in the sprint were able to grow towards the end (negative pacing), while they were always slower over Olympic distance and halfway, see [Positive Pacing), see https://pubmed.ncbi.nlm.nih.gov/25557388/

Triathlon and health

The impact of triathlon training and racing on athletes’ general health A current overview examines the influence of triathlon on health. Although relatively little has been published in this context, it is known that in 1.5 cases to 100,000 starters is a death to complain, mostly when swimming.
