Training-intensity distribution during an ironman season: relationship with competition performance A Spanish group has studied in Ironman Triathletes whether there is a connection between the intensity in training and the Ironman competition time. The largest part of the training was carried out in deep intensity while the race was at a higher intensity.

It showed that a better competition time resulted when the athletes trained in a more deeper intensity. The very insightful work can be found under https://pubmed.ncbi.nlm.nih.gov/23921084/

Fatigue of breathing at an ultramarathon

Aspects of Respiratory Muscle Fatigue in a Mountain Ultramarathon Race For runners in a 110 km mountain marathon with almost 6000 meters, the breath muscles were tested before and after the barrel.

It showed that the barrel led to a restriction of breathing for the inspiration as the Expiration. The details are under https://pubmed.ncbi.nlm.nih.gov/25033264/

Hyponatremia in ultra skiers

Body Weight, Serum Sodium Levels, and Renal Function in an Ultra-Distance Mountain Run An Australian group has studied the difference between a planned and free fluid supply at an ultramarathon over 85 km. A hyponatemia was only for 2% of the runners and the sodium mirror in the blood after the run correlated with the fluid supply.

A moderate fluid intake seems to be the best way to run into a hyponatemia. The work is under https://pubmed.ncbi.nlm.nih.gov/25010155/

The age of the best ultra-rider

Age and ultra-marathon performance - 50 to 1,000 km distances from 1969 - 2012 We examined the age of the best ultra raid of 50 km to 1000 km over the period from 1969 to 2012 with the question of whether the runners in the longer routes are older than on the shorter routes. For women, the age of the 10 fastest runners was 40 ± 4 years above 50 km, 34 ± 7 years above 100 km, 42 ± 6 years above than 200 km, and 41 ± 5 years above 1,000 km.It was a significant difference between 100 km and 200 km and between 100 km and 1000 km. For men, the age of the 10 fastest runners was 34 ± 6 years above 50 km, 32 ± 4 years above 100 km, 44 ± 4 years above 200 km, and 47 ± 9 years above 1,000 km.The age was over 50 km deeper than over 100 km and 200 km, and also deeper over 100 km than over 200 km and 1000 km. Over the years, the age of the fastest 10 women fell over 50 km from 39 to 32 years and among men from 35 to 33 years.Over 100 km remained constant at 34 years in men like women. Over the years, both women like men were over 50 km and 100 km faster.The bottom line was the best male 1000 km runners around 15 years older than the best 100 km runners and the difference was the difference about 7 years.

What happens at 120 km swimming?

Biochemical and hematological changes following the 120-km open-water marathon swim. A Polish group has accompanied a 61-year-old swimmer on his journey over 120 km. The athlete needed 27 hours and 33 minutes for this route.The body core temperature fell from 36.7 ° C to 35.1 ° C.

Different blood levels rose partly considerably. More details about this case under https://pubmed.ncbi.nlm.nih.gov/25177192/

What happens to the cartilage with an ultra

Biochemical cartilage alteration and unexpected signal recovery in T2* mapping observed in ankle joints with mobile MRI during a transcontinental multistage footrace over 4486 km The trans-Europa run over almost 4500 km was measured by a group of runners the cartoon thickness in the ankle.

It showed that it came to a cartilage regeneration in the second half of the run. The work can be found under https://pubmed.ncbi.nlm.nih.gov/25132208/

Lung function at Ultramarathon

Changes in lung function during an extreme mountain ultramarathon. An Italian group has studied the influence of an ultramarathon (330 km and 24'000 meters) on lung function. Before, during and after the course, the runners had to have a battery of lung function tests above themselves.

It showed that the lung function has increasingly decreased over the course of the competition. The work can be found under https://pubmed.ncbi.nlm.nih.gov/25262823/

Swimming through the Adriatic

Pacing and Mood Changes While Crossing the Adriatic Sea From Italy to Albania: A Case Study. An Italian group has accompanied a swimmer who swimmed 78 km through the Adriatic Sea of Italy to Albania. During the nearly 24 hours of swimming, the float went through heights and depths as well as an increasing fatigue.

Surprisingly, the cortisol levels rose to 23 times the output value. All details about this performance can be found under https://pubmed.ncbi.nlm.nih.gov/25310382/
