Infodemiology in the triathlon

Infodemiological data of Ironman Triathlon in the study period 2004-2013 We have studied as often triathlets (and other people) since 2004 on the search engine Google search for the term Ironman Triathlon. The search was cyclically over the years, correlated with the number of annual finishers and women were more often surfing than men.Younger athletes who survived much more often on the Internet were much less on the competitions.

There was also a connection to the men between cycling and demand on the Internet as well as a connection between the countries with most medals and searches on the Internet. The somewhat exceptional study can be found under https://pubmed.ncbi.nlm.nih.gov/27642618/

Laboratory changes in younger and older ultra skills

Predicting race time in male amateur marathon runners So far, there have been some attempts to develop formula to predict the marathon period as accurately as possible. A Spanish group has now measured various variables (physique, training, muscle strength, ruffier test) in 84 men and looked at which variables the time can be predicted.Many of the variables correlated with the term. There were 2 models in which body fat, changing the heart rate in recovery after the ruffier test and the half-marathon time (model 1) as well as body fat, change in heart rate in recovery after the ruffier test and the 10 km time (model2) The competition time could predict best. The complete analysis can be found under https://pubmed.ncbi.nlm.nih.gov/27385548/

Laboratory changes in younger and older ultra skills

Changes in blood morphology and chosen biochemical parameters in ultra-marathon runners during a 100-km run in relation to the age and speed of runners A Polish group according to various laboratory values measured at a 100 km run and examined whether the changes in values depend on the age of the runners.They have decreased in 14 men at a 100 km run before, during and after the run blood values. It came to an increase in myoglobin and bilirubin.The change in the number of white blood cells correlated with the muscle damage.

Performance development at age group swimming in breast swimming

Performance Trends in Age Group Breaststroke Swimmers in the FINA World Championships 1986-2014 The performance in breastfeeds has so far been studied only for top swimmers. We have now collected all the results of the FINA World Masters Championships from 1986 to 2014.During this time, Totally 16,160 women and 18'983 men in the age groups went to the start 25-29 years to 95-99 years.Over the years, the times improved in all ages. It showed that the men in the age groups were 25-29 to 85-89 faster than the women.On the other hand, women in the age groups 90-94 to 95-99 were equal to the men. The women were able to reduce the distance from the men between about 40-75 years over the years, but not in the younger resp.Older age groups. It can be assumed that age class floats at international level can improve their achievements in the next few years and decades. All other details under https://pubmed.ncbi.nlm.nih.gov/27604135/

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. The very insightful work can be found under https://pubmed.ncbi.nlm.nih.gov/27618242/

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/
