Characteristics of the Norseman

Performance and Sex Differences in ‘Isklar Norseman Xtreme Triathlon’ The performance and gender difference was examined for long-distance triathlets especially on the ‘Ironman Hawaii’.Since 2003, the ‘Isklar Norseman Xtreme Triathlon’ has also passed through the Ironman distance. In contrast to the tropical climate on Hawaii, the athletes have to go around there with the cold: swimming with water temperatures of ~ 13-15 ° C, cycling at air temperatures of ~ 5-20 ° C and run at air temperatures of ~ 12-28 ° C inThe level and ~ 2-12 ° C in the target in GaustToodoppen. We now examined the performance of performance and the difference between the sexes between 2003 and 2015. It showed that the number of finishers increase and the relationship man / woman decreased.If you take all the men and all women as a unit, then the men were faster on the bike, but not swimming and not when running.

How do you avoid bubbles on the feet while running?

Etiological Foundation for Practical Strategies to Prevent Exercise-Related Foot Blisters The American Martin Hoffman puts together the reasons for blistering in runners in an overview article and draws the conclusions as they can avoid blistering.

Recommendations for the fluid supply under load

Are we being drowned by overhydration advice on the Internet? We know that excessive fluid intake is potentially dangerous. An American group has sought Google looking for what recommendations on fluid supply and performance exist.

It showed that a large part of the information on the Internet recommends too much to drink while stress. The full work can be found under https://pubmed.ncbi.nlm.nih.gov/27548748/

Body weight and body temperature in an ultramarathon

The influence of hydration state on thermoregulation during a 161-km ultramarathon In general, it is assumed that a loss of more than 2 kg of body weight increases the risk of hyperthermia in an endurance burden.In this study, an American group has studied whether a loss of two and more kg body weight leads to an increase in body core temperature. For thirty runners at a 100-mile run, body weight and body core temperature were measured before, during and after the barrel.It showed that the body core temperature had no connection with the change in body weight or the closing time.On the other hand, there was a connection between the change in body weight and the competition time by the fastest runners the most weight losses. Also important was the realization that a decrease of more than 3% body weight does not lead to an increase in body core temperature.

What happens to a wheel marathon with the immune system?

Pro- and anti-inflammatory cytokine responses to a 164-km road cycle ride in a hot environment. An American group has studied at a wheel marathon in the heat what happens with specific interleukins. The bottom line was a quick final time rather to a suppression of the immune system leads than a rather slow time. The detailed analysis can be found under https://pubmed.ncbi.nlm.nih.gov/27522585/

Changes during a mountain ultramarathon

Muscle damage, physiological changes, and energy balance in ultra-endurance mountain-event athletes A Spanish group has examined specific biochemical and physiological changes after a mountain ultramarathon. In 11 runners, an increase in myoglobin, creatine kinase, lactate dehydrogenase, troponin I, leukocytes, as well as thrombocytes.

The barrel led to an energy deficit with the decrease in body weight and the sizes of the extremities. All numbers can be found under https://pubmed.ncbi.nlm.nih.gov/27447685/

The performance of 100-year-old athletes

Centenarian athletes: Examples of ultimate human performance? So far, benefits of age group athletes were examined for up to 80-90 years.A French group has analyzed world record performance of 100-year-old athletes. Above all, services in the sports athletics, swimming and cycling were taken into account.Overall, 60 world clords could be found people at an age of 100 years or older. These records were achieved through 19 athletes, 1 cyclist, 10 athletes and 8 swimmers.

What influences the recovery in a 100-mile running?

Determinants of recovery from a 161-km ultramarathon An American group examined whether there are variables that provide an indication of an accelerated recovery after a 100 mile run. UltraRauer at a 100 miles run had to complete 400 m runs before and after the race, the CK was measured after the race and a questionnaire had to be filled out.It turned out that the height of the CK is the most important variable after the run.

Hyponatiums in the ironman-em

Hyponatremia among Triathletes in the Ironman European Championship From 2005 to 2013, a German Group examined the prevalence of the stress-assisted hyponatremia at Ironman Triathlon at the Ironman EM. During this period, 932 men and 157 women were investigating what the largest world’s largest group was investigated to Ironman Triathlen.Throughout the collective of 1089 finishers, 115 athletes (10.6%) developed a hyponatremia, including 3 athletes (0.3%) a critical hyponatremia.

It showed that the female gender and long competition time clearly correlated with the occurrence of a hyponatremia. The work can be found under https://www.nejm.org/doi/full/10.1056/nejmc1510409
