Self-report Versus Direct-Measurement for Assessment of Fluid Intake During a 70.3-mile Triathlon An American group has studied how exactly triathlets can estimate their supply of fluid on the running track of half a Ironman triathlon. Compared with a precisely measured intake, the self-assessment was not bad, with certain individuals clearly laying down. The work can be found under https://pubmed.ncbi.nlm.nih.gov/25561580/
Read morePacing strategies during the swim, cycle and run disciplines of sprint, Olympic and half-Ironman triathlons An Australian group has studied the pacing behavior of triathlets via Sprint, Olympic Distance and Halber Ironman.8 male triathlets were analyzed during swimming, cycling and running.
The speed remained constant at all routes. When cycling, the pacing was not uniform.When running, the triathlets in the sprint were able to grow towards the end (negative pacing), while they were always slower over Olympic distance and halfway, see [Positive Pacing), see https://pubmed.ncbi.nlm.nih.gov/25557388/

The impact of triathlon training and racing on athletes’ general health A current overview examines the influence of triathlon on health. Although relatively little has been published in this context, it is known that in 1.5 cases to 100,000 starters is a death to complain, mostly when swimming.

Read moreEnergy Balance of Triathletes during an Ultra-Endurance Event A Spanish group has studied the energy balance with Ironman triathlets. For swimming, cycling and running, energy consumption was calculated exactly.The 11 triathlets were around 755 minutes, had an average heart rate of 137 beats, raised around 3,600 kcal, spent around 10,000 kcal and came to a deficit of around 7,400 kcal.In addition, it came to a decrease in body weight and body water.

Read moreSodium Supplementation and Exercise-Associated Hyponatremia during Prolonged Exercise On the ‘Western States Endurance Run’ over 100 miles was studied by the supply of salt a bit brings with respect to stress-induced hyponatremia.In the whole collective, 6.6% of the runners came to a hyponatremia.
Over 90% of the runners took a salt preparation to themselves. It showed a direct connection between the sodium value in the blood after the competition and the supply of sodium during the course.However, there was no difference in the sodium supply between runners with and without hyponatremia at the end of the run. The supply of sodium is much less important than a restriction of the fluid supply to avoid a hyponatremia in the ultramarathone. Can be found under https://pubmed.ncbi.nlm.nih.gov/25551404/

Longitudinal Assessment of the Effect of Age and Experience on Performance in 161-km Ultramarathons An American study examined at 4,066 runners with their 29'311 competitions from 1974-2010 the influence of age on the mileage at 100-mile runs. By the age of 38, men like women were slower at 0.05-06 h / year. Between 38 and 50 years, men were slower 0.17 h / year, the women 0.23 h / year.

Studies with runners, cyclists and participants in Olympics showed, but that a regular endurance training has a protective effect from cardiovascular diseases.

Marathon run: cardiovascular adaptation and cardiovascular risk A current compilation describes the cardiovascular risk for marathon runners. In the age group of 40-65 years, there is an increased risk of rhythm disorders.Although a marathon is an intensive physical stress with a burden on the cardiovascular system, there is still no circulatory death cases in the marathon. The interesting compilation can be found under https://pubmed.ncbi.nlm.nih.gov/24408890/
