Something to the psychology of ultra skiers

Psychological Attributes of Ultramarathoners An American group has studied psychological aspects of ultra skills.At the ‘Bear Chase Trail Race’ all 200 starters were requested and 98 (48%) filled out the questionnaire. Around 20% of the runners had signs of an addiction, also around 20% showed signs of depression. The largest part of the runners, however, showed a great social retention of their partners regarding the training and the goals in the field of ultramarathon.

Caffeine improves performance in the triathlon

Caffeine Improves Triathlon Performance: A Field Study in Males and Females A South African group has examined the influence of caffeine on the performance of triathletes. In a randomized double-blind study in crossover design, triathlets got 6 mg caffeine per kg body weight 60 minutes before the burden. The intake of caffeine led to a reduction of 3.7% of the floating time and a reduction of 1.3% of the total time.It is recommended that athletes should take 45-60 minutes before starting to an Olympic triathlon 6 mg caffeine per kg body weight to improve the competition performance.

What happens if you drive 500 km bike in a piece

Performance and physiological analysis of 500 km non-stop cycling: a case study. A Spanish group has examined the change during a cycling over 500 km. Driving speed and wattage continued to go back constantly, with this decline on the rotational speed and not to lead back to the force. The heart rate also slowly decreased.In addition, a decrease in heart rate variability, a pronounced inflammation, and signs of a muscle damage.These changes remained up to 2 days after the end of the load.

At 94 years completed a 6-hour run

Pacing in a 94-year-old runner during a 6-hour run It’s been known for some time that 90-year runners are able to finish a marathon. The pacing for older runners has already been investigated, but we do not know how an over 90-year-old runner divides a longer barrel. We have studied a 94-year-old man at the 6-hour run ‘in Brugg a 94-year-old man who has completed a 6-hour run in preparation for a marathon for the M95 age group.During the 6 hours he reached a distance of 24.304 km. The running speed took practically linear over time.The measurements with bioelectric impedance as well as the determination of various laboratory values over time after the competition revealed that the run had no negative impact on the health of the runner.

Seven marathons in seven days

Fluid metabolism in athletes running seven marathons in seven consecutive days In recent years, multilayer runs have become increasingly popular. To date, however, a study has never studied what happens in the fluid balance when runners run a marathon every day during 7 days. We have used 26 runners (6 women and 20 men) the day before the start, then after day 1, day 4 and day 7 different parameters of the fluid budget and also calculated further parameters. It came to a decrease in body weight, body fat and hematocrit.An increase could be recorded for plasma osmolality, urine osmolality, potassium in urine, specific gravity, urine, urea in the blood, as well as in urine, and the transstubular potassium gradient.

94-year-old climber

Marcel Remy - At 94 years on the summit $ Marcel Remy, father of the Swiss climbing icons Claude and Yves Remy, climbs the 450m high northwest wall of the famous Miroir de l’Argentine in the Western Swiss Alps at 94 years. https://www.youtube.com/watch?v=nujnzecc7hw Displays the film about this extremely exceptional performance and https://community.mammut.ch/t5/mammut-blog/marcel-remy-mit-94-jahren-auf-dem-gipfel/ba-p/3301 brings details aboutThis extraordinary man.

His performance shows that you can also provide benefits in higher age that you have considered absolutely impossible earlier.

Kidney function and ultramarathon

Glomerular Filtration Rate is Unchanged By Ultramarathon A Polish group has studied the influence of a 100-KM run on renal function. Often the kidney function is determined on the basis of the determination of the creatinine or the estimation of the glomerular filtration rate. In this study, every 25 km laboratory was made during a 100 km run and to calculate the effective glomerular filtration rate.In 17 runners showed by the run an increase in creatinine, urea and uric acid.The creatinine has increased by around 25%.

Aspects of anemia in ultra skills

The changes of red blood cell viscoelasticity and sports anemia in male 24-hr ultra-marathoners A group of Taiwan examined the phenomenon of sport-induced anemia at a 24-hour run. Special phenomena were examined like the viscoelasticity of the red blood cells.It shows that the race led to a waste of haptoglobin, red blood cells, hemoglobin, and hematocrit. On the other hand, there was an increase in reticulocytes and ferritin.In 15 out of 19 runners, there were changes in the viscoelasticity of red blood cells.

Medical emergencies in a half-ironman

Medical support during an Ironman 70.3 triathlon race A Korean group has studied what happens during a medical point of view during a half-ironman. As part of the race, 187 triathlets needed medical help.In swimming, an athlete cramping suffered into the calf, 19 triathlets needed medical support during the bike range and 159 athletes had to be treated medically during the running track.

Five athletes had to be driven with the ambulance in the hospital for problems on the bike path. The whole work can be found under https://f1000research.com/articles/6-1516/v1
