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.

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/

Nutrition for swimming in open waters

Case Study: Competition Nutrition Intakes during the Open Water Swimming Grand Prix Races in Elite Female Swimmer. A Czech group has the diet of a swimmer in 7 occasions of 15-88 km resp.3-12 hours duration analyzed. Per hour, the swimmer took around 83 g of carbohydrates and 12 g of egg whites during the fat loss was around 1G.

Per competition lesson gave the approximately 390 kcal energy supply. The whole analysis can be found under https://pubmed.ncbi.nlm.nih.gov/26731793/

Meaning of swimming, cycling and running for triathlon

Changes in Contributions of Swim, Cycle, and Run Performances on Overall Triathlon Performance over a 26-year period The French sports scientist Romuald Lepers has studied how strong the disciplines swimming, cycling and running performance in a triathlon. For this he has taken the 50 fastest athletes about the short distance and the Ironman distance from the years 1989 to 2013.On the short distance, the athletes were swimming and running faster, but there was no change in cycling time and the total time. On the Ironman track the wheels and maturities and the total time were faster, but nothing happened when swimming.Swimming made about 18% on the short distance, running with 47% and 36% cycling made a much larger part.At the Ironman, cycling and run about 40%.
