Influence of extreme duration on the body

Moving in extreme environments: extreme loading; carriage versus distance In a recent review, a group of researchers has described the influence of extreme external influences on the body.

The effect is discussed on different organ systems such as motion apparatus, cardiovascular system and metabolism. The highly recommended compilation can be found under https://extremephysiolmed.biomedcentral.com/articles/10.1186/s13728-016-0047-z

Preparation for a marathon

Marathon - The way is the goal In a review article, the most important aspects for successful marathon participation will be explained. It is recommended for marathon runners to make an ECG with a detailed anamnesis and physical examination, together with 35 years. In older athletes over 65 years, a stress ECG should be made.

In order to avoid stress fractures, a weekly running distance of 60-70 km should not be exceeded. All good tips for successful preparation can be read on https://www.medicalforum.ch/docs/smf/2016/15/en/smf-02625.pdf

Preparation for 78km swimming

Training for a 78km solo open water swim: a case report. An Italian group has accompanied a swimmer in preparation for the crossing of the Adriatic Sea by Italy to Albania. In the 32 weeks before swimming over 78 km all workouts were registered.

The athlete completed between 15 to 70 swimming kilometers per week. All details of the preparation can be found at www.ncbi.nlm.nih.gov/pubmed/27054351

Study Protocol of the Nurmi study

Prevalence in running events and running performance of endurance runners following a vegetarian or vegan diet compared to non-vegetarian endurance runners: the NURMI Study We have now published the study protocol for the Nurmy Study and completed the data collection. After the meeting in March of this year, we will now start the analysis of the data. The Protocol for the study is online at https://springerplus.springeropen.com/articles/10.1186/s40064-016-2126-4

Pacing im Marathon

Pacing, packing and sex-based differences in Olympic and IAAF World Championship marathons A British researcher has studied the pacing behavior of elite marathon runners at Olympia and the World Cup. He has analyzed the section times of 673 men and 549 women from 9 races.Future medal winners kept their pace from kilometers 10 to the finish.

To run at a marathon at a high level to the top, you should find competitors at the beginning of competitors that start relatively slowly and then keep the tempo to the end. The interesting analysis can be found under https://pubmed.ncbi.nlm.nih.gov/26736042/

Performance trends in progress

One hundred and fifty years of sprint and distance running - Past trends and future prospects In recent years, the maturities in the sprint as well as medium and long distance have improved significantly. It looks so that women will be 10-20% slower even in the future than the men, a time of 9.50 over 100m is possible at the end of this century, occasionally, records of medium and long distance will be broken over the next 20-30 years andA marathon time of less than 2 h is probably unlikely until the end of this century. The very insightful analysis can be found under https://pubmed.ncbi.nlm.nih.gov/26088705/

Strategy in an Extremberg

Sleep Management Strategy and Performance in an Extreme Mountain Ultra-marathon A French group examined the running and sleep behavior of runners at the UTMB in 2013. 72% of the finishers did not go to sleep for 28% sleeppourers.Runners without sleeping pauses were faster in the finish as runners with sleeping breaks.It showed up the runner who had dealt with the strategy for the course before the run was much faster.

Blood sugar course for a 100 km running

Continuous glucose monitoring during a 100-km race: a case study in an elite ultramarathon runner. A Japanese group has measured blood sugar with two 100 km runners under load and examined whether there is a connection with the running speed. The two runners a sensor was implanted in the subcutaneous fat on the stomach and the sugar values could be measured so continuously.The one runner came after 6:51 h: min in the finish, the other after 8:56 h: min. The faster runner was around 90% of its lactic shaft, slower at around 78%.The faster runner took only 249 g of carbohydrates during the race, the slower, however, 366 g.

Sodium supply and dehydration

Is Sodium Supplementation Necessary to Avoid Dehydration During Prolonged Exercise in the Heat? An American group has studied at a 100 miles run if sodium supply can prevent dehydration. At temperatures up to 39 ° C, the weight was determined as well as calculated by questionnaires the supply of liquid and sodium.

The researchers came to the conclusion that a sodium supply has no influence on the hydration of the runners. The whole study can be read below https://pubmed.ncbi.nlm.nih.gov/26907835/
