The weather influence at the marathon in Boston from 1972 to 2018

The role of weather conditions on running performance in the Boston Marathon from 1972 to 2018 This study examined the relationship between the weather conditions along with gender and country of origin with the mileage at the Boston Marathon from 1972 to 2018. A total of 580,990 observations of 382'209 different finishers with generalized additive mixed models were analyzed. Different groups and subgroups were considered as all runners, rank 101-200, 21-100, top 10 and the winners.The weather conditions in the course of the event were the average air temperature (° C), total precipitation (mm), the so-called WBGT (° C), the wind speed (km / h), the wind direction (front wind, side wind, tailwind) and barometric pressure (HPA). These effects were examined in a multi-variable model, together with gender, country of origin, calendar year, an interaction expression Country: Gender and a spline smooth term depending on calendar year and gender. In an increase in average temperature by 1 ° C, the performance was deteriorated (at 00:01:47 H: min: sec for all finalists and at 00:00:20 H: min: sec for the annual winners).Backwind improved the performance of all groups. The increase in precipitation was significant, which was due to the deteriorated performance in all groups except for the annual winner. The increasing wind speed was also associated with a deterioration of performance in all finishers and elite groups. Kenyans and Ethiopians were the fastest nationalities.The gender differences (men in all groups faster than women) were greatest in elite groups.

Hyponatriämie im Marathon

Exercise-Associated Hyponatremia During a Self-Paced Marathon Attempt in a 15-Year-Old Male Teenager The increased participation in endurance sports such as marathon runs has found scientific interest, especially in adult athletes. In a few studies, however, it was examined how a marathon has an effect on children and adolescents.The present case study had 2 objectives: first, the description of the pacing during a marathon and secondly the examination of the acute reactions of the blood physiological and biochemical parameters during the race (before and after the race) and at five consecutive days after the race. The participant was a 15-year-old boy, who completed a marathon attempt for the first time and ended in 5 h 19 m 53h. Positive pacing was observed (a running speed decreasing during the race) with a final spurt.An increase in fluid intake over the race has been shown.A stress-associated hyponatremia (eah, plasma sodium concentration <135 mmol / l) was found after the race.C-reactive protein (CRP) correlated neither with creatine kinase (CK) nor lactate dehydrogenase (LDH);However, leukocytes correlated very strongly with LDH, but not with CK.CK and LDH were almost perfect with creatinine correlated.In addition, the creatinine clearance correlated very strongly with CK, but not with LDH.Leukocytes, transaminases, LDH and CK turn off after the race from the physiological field, but return to normal values within the five-day recovery phase.

The heart in the marathon

Cardiovascular stress biomarker assessment of middle-aged non-athlete marathon runners The cardiovascular security of marathon runs remains unclear.This study examined the impact of a marathon on the profile of biomarkers for cardiovascular burdens associated with transthoracic echocardiography.Thirty-three healthy male amateur runners, which were ≥ 50 years old (average age 57 ± 7 years), were examined. Venous blood samples were won in front of the marathon shortly after the race, 2-4 days and 7 days after the marathon.The plasma concentrations of highly sensitive heart troponin I (HS-CTNI) and endothelin-1 were measured.The N-terminal Pro-B-type natriuretic peptide was measured using electrochemiluminescence. Each participant had a transthoracic echocardiography before and immediately after the race. It showed a strong increase in biomarkers after the race, which was normalized after 2-4 days and remained in the normal range after 7 days. Runners with intensive training programs (> 169 km / month) after the race had a lower HS-CTNI. There were a decline in the left atrial volume volume and an increase in the maximum right atrial volume. Changes in the Doppler indices of the diastolic function were observed, which indicate a change in left ventricular relaxation. A marathon is associated with a strong and significant increase in biomarkers.

The weather at the estate marathon and the influence on performance

The Role of Environmental Conditions on Marathon Running Performance in Men Competing in Boston Marathon from 1897 to 2018 This study examined the effects of weather conditions on the performance of men during the Boston marathon from 1897 to 2018. A total of 383'982 observations of 244'642 different finishers were analyzed using generalized additive mixed models. All runners, TOP-100 and TOP-10 were considered.The weather conditions on the race day were average air temperature (° C), precipitation (mm), WBGT (° C), wind speed (km / h), wind direction (N, S, W, E) and pressure (HPA). These effects were examined in multivariable models with spline smooth conditions depending on the calendar year.In an increase in temperature by 1 ° C, the performance was deteriorated for all groups.The west of the west of the wind, compared to the wind from other directions, was most favorable for the performance of all finalists.Increasing rainfall deteriorated the performance of the top 100 and the top 10.With an increase in wind speed by 1 km / h, the performance was worse for all finishers, but not for the top 100. Pressure and WBGT were examined in unvariable models.Overall, the achievements with increasing pressure worsened and WBGT.

The women come closer to men in the marathon

Nutrition in the 24-h running

Nutritional Knowledge and Dietary Practice in Elite 24-Hour Ultramarathon Runners: A Brief Report Several factors contribute to sporting performance, and the diet is a key component.A higher level of nutritional knowledge seems to correlate with a higher nutritional quality.However, this is still little explored and the results are still not conclusive. The aim of this study was the evaluation of nutritional knowledge and the adequacy of diet in order to recognize potential potential relationships between these two factors in 24-hour elite ultramarathon runners, a sport that seems to win popularity in the last decade. Nutrition and adequacy of the Mediterranean diet were rated on the basis of validated questionnaires to 10 elite ultramarathon runners (six male and four female) of the Italian Ultramarathon and Trail Association (IUUTA). The general nutritional knowledge throughout the sample of the athletes seemed to be good, especially with regard to “nutritional recommendations” and “nutrient sources”.However, women had higher total materials for food knowledge compared to men.Finally, a linear regression analysis showed that better nutrition knowledge was positively accompanied by an increase in adequacy degrees of the Mediterranean diet, with the level of education being adapted.

Pacing im Duathlon

The Combined Effect of Aging and Performance Level on Pacing in Duathlon – the “ITU Powerman Long Distance Duathlon World Championships” The role of age and performance level was examined for runners such as marathon runners, but not in athletes with several sports such as Duathlon (running, cycling and running).The aim of the present study was therefore to examine the combined effects of aging and performance at the pace of Duathlen, which participate in two different spacer races. Pacing (defined as a relative portion of the bicycle time in% for the total time of the race) was analyzed for 6,671 Dathlets, which from 2003 to 2017 in the short distance race (10 km first run, 50 km cycling and 5 km second run) and in the long-distance race (10 km first run, 150 km cycling and 30 km of the second run) of “Powerman Zofingen”, the “ITU Powerman Long-distance Duathlon World Championships”. Men were faster, older and spent less time (%) with cycling as women in both races.Younger age groups spent more time (%) by cycling than their older colleagues in women (both short and long distances) and men (long-distance races).Fast performance groups spent more time (%) by cycling than their slower colleagues.In the short distance of men, an interaction of the small age group × performance group was observed on time (%) - but not in the long distance or in women - with smaller differences between the operating groups of the older group than in the younger age groups. Women, young and fast duathles were relatively slower than men, old and slow duathles in the wheel. That is, old dathlets were relatively faster than running when cycling.
