The meaning of the crew at the Raam

Participating In The Race Across AMerica In A Team Of Eight Cyclists: Do Not Neglect Crew Preparation. The Race Across America (RAAM) is considered one of the longest and hardest cycling races in the world.It can be done alone or in a season of two, four or eight people. The aim of the present study was to examine various physiological, perceptual and psychological reactions, during and after RAAM in a team of eight amateur vehicles. Since the logistics of the entire team is demanding and complex, the crew members have applied the same test procedure.The main result was that the parameters in cyclists in the course of the RAAM were not changed globally than with crew members, and that all variables returned to the level a week after the race in both groups in front of the race. In the crew, the body fat was reduced in the middle of the race (center) compared to a week before the Raam (pre) (-1.5%) and the entire body water in the middle before the race increased (+ 2.5%).Therefore, the execution of the race with eight well-prepared amateur vehicles seems to reduce the potential health risks. In the crew, the strength of the quadrice for each valuation date remained stable, but the general fatigue increased during the entire race. The most important message of this study is that crew members need adequate and sufficient preparation and training for an eight-member team.Roles and responsibilities must be thoroughly defined.Individuals must know each other and be prepared for sleep deprivation.

Cardiale biomarker in the ultramarathon

Blood cardiac biomarkers responses are associated with 24 h ultramarathon performance. The clinical significance of the response of heartbiomarkers in ultra-runners is not fully clarified as the runs in terms of route and duration vary and the competitors modulate the running intensity according to individual travel capacity. The aim of this study was to examine the relationship between the self-chosen training intensity and heartbiomarkers by comparing experienced (n = 11) and inexperienced (n = 14) runners, which a 24-hour ultramarathon with significant differences in performancecan finish.Heartbiomarker (CKMB / Totalck, CTNT and NT-Probnp), inflammatory markers (leukocytes and CRP) and cortisol were analyzed before and after a 24-hour ultramarathon. Experiencing runners ended the race with a significant longer distance as inexperienced runners (158.8 ± 15.8 versus 116.8 ± 10.3 km). The evaluation showed a significant interaction between time and performance level with a greater increase in CTNT, NT-Probnp and Cortisol in the group of experienced runners.CKMB / Totalck decreased, while leukocytes and CRP climbed in both groups.Correlations between traveled distance and cortisol, CKMB, CTNT or NT-Probnp were found.Cortisol and NT-Probnp were also significantly correlated. Although there are no clear indications of a heart risk, if cardiac biomarkers are compared with clinical limits, cardiale biomarkers are associated with the mileage and the reaction of the hypophysen adrenal tongue system.

Digestive problems with runners

Gastrointestinal Complaints and Correlations with Self-Reported Macronutrient Intake in Independent Groups of (Ultra)Marathon Runners Competing at Different Distances This study examined the differences in gastrointestinal and stress-related complaints between groups of runners competing in different running routes, using web-based questionnaires. A total of 89.3% of the runners were reported heavy complaints during the race, compared with 70.6% after the race. Significant differences between the groups have been described for marathon runners and ultramarathon runners. During the competition, the runners reported about urinary rang (47.7%), muscle cramps (43.6%) and belching (43.6%).The prevalence of bloating, flatulence, side pain and dizziness was different in different running tracks. There were small to medium-sized negative correlations between food intake and fluid intake and gastrointestinal complaints. After the competition (12 h), 70.6% of the participants assessed complaints, with muscle cramps (47.6%), wind disruptions (19.0%) and flatulence (12.7%) most common.The frequency of belching, nausea, stomach cramps and muscle cramps differed between the distances. There were small to high positive correlations between complaints during and after the competition. In summary, runners of all distances reported a high prevalence of gastrointestinal complaints and other stress complaints. There were some small differences in terms of the type of message and the severity of the complaints between the distances.

The age of the best marathon performance - Berlin Marathon

The Age-Related Performance Decline in Marathon Running: The Paradigm of the Berlin Marathon The variation of the marathon period by age group was recently used to model the decline in endurance with increasing age. However, the previously studied paradigms for marathoning come mainly from the USA. The aim of the present study was therefore to investigate the age of the highest performance in the marathon at a European race, the “Berlin Marathon”. In this marathon of 2008 to 2018, the maturities of 387'222 finishers (women n = 93'022; men n = 294'200) were investigated. Men were +1.10 km / h faster (10.74 ± 1.84 km / h compared to 9.64 ± 1.46 km / h) and +2.1 years older (43.1 ± 10.0 years compared to 41.0 ± 9.8 years) as women. The age of the highest performance in the Marathon was 32 years in women and 34 years in men in 1-year age groups and 30-34 years in women and 35-39 years in men in 5-year age groups. The performance of women and men in ages 60-64 and 55-59 corresponded to “90% of the running speed at the age of the maximum performance in the marathon.

Does age really limit our stamina?

Endurance and Age-Related Performance Our work Nikolaidis, P.T., & Knechtle, B. (2018).Performance in 100 km Ultra-Marathoners - At Which Age IT Reaches Its Peak?Journal of Strength and Conditioning Research is content this comment by Jeremy Sutton.

In his article, he describes the phenomenon that ultramarathon is a domain of older runners and brings some examples. The item is to be read under https://medium.com/explore-the-limits/endurance-and-age-related-performance-25b0f290544

Pacing in half marathon and marathon

Performance and Pacing of Age Groups in Half-Marathon and Marathon The aim of the present study was to investigate the age-related differences in performance and pacing in a half marathon compared to a marathon. All Finishers (N = 9137) of the Half Marathon (N = 7258) and the Marathon (N = 1853) Ljubljana 2017 with available data for intermediate times during the race were analyzed on the pacing. Half marathon runners were slower at women than marathon runners (2.77 ± 0.35 compared to 2.86 ± 0.39 m / s), but faster in men (3.14 ± 0.45 compared to 3.08 ± 0.46 m /s). In both races, the age group was <25 years the fastest and age group> 54 years slowest. All age groups showed a positive pacing (decrease in speed in the race) in both the renown distances and the sexes, each segment being slower than the previous one. In the marathon, however, a final spurt was observed, but not in the half marathon. For most age groups, the pacing in the half marathon was more even than in the marathon.
