Pacing im Marathon

The influence of pacing strategy on marathon world records The pacing is crucial for different sports and different routes. A Spanish group has studied the pacing of elite marathon runners in the context of new world records in the last 50 years. She shared former marathon record holder in two groups: classic athletes (record holder between 1967 and 1988) and contemporary athletes (record holder between 1988 and 2018). The total distance of the marathon was divided into 8 sections of 5 km and 1 last section of 2.195 km, and the relative average speed of each section was calculated individually. On average, the athletes in the first half marathon were a little faster than in the second half marathon, where they progressively slowed. When comparing classical and contemporary athletes, however, they observed that classic athletes started significantly faster, although their speed decreased dramatically after 25 km and was significantly slower than in their simultaneous counterparties. The study showed that the pacing strategies of the best marathon runners in the world have changed in the last 50 years.

MRI of the spine at top athletes

Evaluation of spine MRIs in athletes participating in the Rio de Janeiro 2016 Summer Olympic Games For top athletes who participate in world level, such as the Olympic Games, many spine diseases arise due to overuse, other spinal problems are the result of acute injury. A research group has tries to analyze the epidemiology of spinal disorders in athletes participating in the 2016 Olympics in Rio de Janeiro based on MRI.In a retrospective study, all spine MRIs were analyzed, which were carried out during the 2016 Olympics in Rio. Of 11,274 athletes participated in the Olympic Games, 100 athletes received a MRI of the spinal columns. Twenty-five of the 100 (52%) athletes, which received a MRI of the cervical spine, the thoracic acid column and / or the lumbar spine, showed a moderate to heavy spinal disease. The highest sport-specific incidence of medium-heavy to heavy spinal disease was observed in diving trips (67%, 3 per 100 divers). Weightlifting had the second highest sports-specific incidence of spinal disorders (67%, 1.5 per 100 weightlifters). In the athletics, most spine MRIS (31 out of 107 mris, 29%) were carried out.European athletes had more spine MRI as athletes of all other continents (55 out of 107 MRI, 51%). Athletes over 30 years had the highest rate of moderate to heavy spinal disorders in MRI (24 out of 37 athletes> 30 years old, 65%).

The best age in cross-country skiing

The Age of Peak Marathon Performance in Cross-Country Skiing-The “Engadin Ski Marathon” The age of the best endurance performance was well examined in running in flat urban marathons. However, we know nothing about the age of marathon high performance in cross-country skiing, which would be of great practical use for athletes and coaches. The aim of the present study was therefore to investigate the age of the best marathon performance in cross-country skiing. Participants were 162,991 men and 34'833 women who approached “Engadin Skimarathon” between 1998 and 2016. We examined the fastest women and men and all finishers in 1-year intervals. The relationship between men to women rose over the years.The men (44.27 ± 0.03 years, 15.73 ± 0.01 km / h) were 5.98 ± 0.07 years older and 2.14 ± 0.02 km / h faster than women (3829 ± 0.06 years, 13.58 ± 0.01 km / h). Looking at the fastest participants in 1-year intervals, the fastest speed for men (30.33 km / h) was reached at the age of 29 years and for women (28.76 km / h) at the age of 24. Taking into account all participants, the highest speed for men (17.69 km / h) was observed at the age of 18, while they were for women (15.76 km / h) at the age of 17.

The age of the best marathon performance

Sex Differences in the Age of Peak Marathon Race Time Until now, studies have studied the age of the best marathon period have proven that women are older than men when they make their best time. We have now analyzed almost half a million runners from the New York City Marathon from 2006-2016. As expected, men are faster than the women, the number of women took over the years dramatically and the largest part of the women was ranked in the age group 30-34 years while the men in the category 40-44 years were most frequently found. If we determine the age of the best performance in 1-year intervals, the women with 29.7 years were the fastest as the men at 34.8 years were their best time. If you take the 5-year groups, so the best times of women in the age group were 30-34 years to find in the men in the age group 35-39 years.

The Usain Bolt of Sprint Greetings

New world record over 100m in the category M100 At the age group runners there are age groups in 5-year classes. At the World Cup, the age group M95 with runners of 95-99 years is actually the oldest group. Now it will probably be new a group M100 with runners from 100-104 years like the swimmers.

The Texan Orville Rogers with year 1917 has placed over 60 m a world record. He sprinted the route in fabulous 19.13 seconds. On the video, this run is full length https://www.blick.ch/sport/leichtathletik/edward-cox-90-usbust-fuer-60-meter-nur-11-73-seconds-das-is-der-usain-bolt-der-sprint-greichen-id8134683.html

The reliability of GPS in sports

Validity and reliability of 10-Hz global positioning system to assess in-line movement and change of direction The use of GPS is very common in sports. The question arises, however, how reliable these devices are.We have now checked the reliability of a GPS system with directional changes in runners and footballers.

It showed that the investigated device measures very reliable. The work can be found under https://pubmed.ncbi.nlm.nih.gov/29599725/

Are the formulas for the maximum heart rate?

Age-predicted maximal heart rate in recreational marathon runners: A cross-sectional study on Fox’s and Tanaka’s equations For a long time, formulas are known on the basis of which one can estimate the maximum heart rate (HRMAX) in sports due to the age of the athlete. Specially mentioned is the formula according to Fox (220-age) and the formula to Tanaka (208-0.7xalter). So far, these formulas have not been validated in marathon runners, despite the importance of the role of Hrmax for training purposes. We have now validated the two formulas at 180 marathon runners.We came to the conclusion that the formulas of Fox and Tanaka overestimated the Hfmax in women by 5 beats per minute, while Fox underestimated the HFMAX in men around \ ~ 3 beats per minute. Therefore, we recommend the use of the formula of Tanaka only in male marathon runners.

The digestion during the sport

Sports and gastrointestinal complaints The impact of sporting activity on the digestive tract were neglected until today in medical research. Studies occupy that gastrointestinal problems occur in a notable proportion of athletes and can lead to performance reduction in training as well as in competition.

Especially in endurance sports, athletes often suffer from symptoms such as nausea, side stings, reflux symptoms or the so-called, runnerdiardrhoe ‘. All new findings can be found under https://medicalforum.ch/en/detail/doi/smf.2018.03159

At what age do you reach the best time over 100 km?

Performance in 100-km ultra-marathoners - At which age it reaches its peak? The number of 100 km runs and the number of successful finishers is rising from year to year. Nevertheless, we still know relatively little as the age of the best performance has developed over this route. We have therefore searched for all successful finishers since 1959 and with over 370,000 successful women and men who have brought such a competition to the goal of examining the development of the age of the best performance. To find this age of the best performance, there are various options such as 5-year intervals or 1-year intervals to consider the best, the top ten or all finishers per group. The age of the highest performance was 40-44 years in women and 45-49 years in men when all finishers were analyzed at 5-year intervals, while the women were 30-35 years and at men 35-39 yearswhen the top ten finishers were taken into account. When the finishers are analyzed at 1-year intervals, we find the age of excellence at 41 years of women and 45 years in men taking into account all finishers, and at 39 years in women and 41 years in men taking into account theTop ten finishers. The age of peak performance was younger at the women than in men, which could reflect the overall younger age of women as men in this discipline. Compared to previous studies, we observed the excellence of around 10 years later than previously known, which is due to an increase in age of the finisher over the calendar years.
