Youthful ultra

Participation and Performance Analysis in Children and Adolescents Competing in Time-Limited Ultra-Endurance Running Events UltraMarathon runs are popular in the adult population increasing popularity, especially due to Masterathlen, which are older than 35 years. Teenagers runners under 19, however, take part in ultramarathons, and an increase was observed at distanced runs.However, there are no data on temporary ultramarathons in this age group. This study examined the participation and performance trends with time-limited ultramarathons, including multi-day events, under runners under 19 years. Between 1990 and 2018, the most popular events recorded a total of 214 places for 6-hour runs, 247 for 12-hour runs and 805 for 24-hour runs. The majority of athletes came from Europe and North America.Only a minority participated in multi-day ultramarathons. Overall, the speed increased with age, but the running speed decreased over all years for 6- and 24-hour runs with increasing number of participants.

Compared 10 km, half marathon and marathon

Number of finishers and performance of age group women and men in long-distance running: comparison among 10km, half-marathon and marathon races in Oslo. The aim of the present study was to examine the number of finishers and their performance trends at 10 km, half marathon and marathon races in Oslo. The data (a total of 115'725 participants; Women, N = 50'595; Men, N = 65'130) of 10 km, half marathon and marathon race in Oslo from 2008 to 2018 were considered taking into account number, gender, age and running speedthe participant analyzes. The total ratio of men to women was the smallest in the 10 km race and the largest in the marathon.Both the women and men, the slowest running speed was achieved in the older age groups. Based on the results of the present study, it was concluded that relatively more women completed a 10 km and less a half marathon and a marathon.

Teenagers swimmer and their performance comparison

Sex differences in youth elite swimming The time and the extent of sexual differences in sporting performance during early human development before adulthood are unknown. The idea of this study was the comparison of the swimming speed of boys and girls for all freestyle swimming events to determine the age of divergence of swimming performance. The 100 best US freestyle swimming times of boys and girls aged 5 to 18 years for the 50 m to 1500 m were collected. The swimming performance improved with increasing age for boys and girls to reach a plateaus that used in girls (15 years) in a younger age than in boys (17 years). Before the age of 10, the top 5 swimming recorder for girls were 3% faster than for the top boys. For places 10 to 50, however, there were no gender differences in the swimming benefit before the age of 10.For both the top 5 and 10th to 50th place, the gender performance difference increased from 10 years to the 17th year of life. For everyone, the gender-specific performance difference at the age of 18 was greater in the sprints (9.6%, 50-200 m) than in the long distances (7.1%, 400-1500 m). In addition, the sexual performance difference over the age and US ranking increased from 2.4% to the first place to 4.3% for the 100th place, indicating a lower power density in the girls than the boys. The annual participation, however, was the girls for all ages in the girls than in the boys. The top 5 girls showed faster swimming speeds and the girls on the 10th to 50th place showed similar swimming speeds like the boys (up to \ ~ 10 years). After the tenth year of life, however, the boys showed increasingly faster swimming speeds until the age of 17 as the girls.

The heart of the runners at the Spartatlon

Exploring the determinants of the cardiac changes after ultra-long duration exercise: The echocardiographic Spartathlon study The idea of this study was the study of the pathophysiological determinants of heart changes after an extremely long burden. 27 runners who had finished a 246 km long race were examined both before and after the end of the race.The investigations included echocardiography and the measurement of body weight as well as biochemical blood parameters. The barrel increased the thickness of the left ventricular end-diastolic interventricular septum (LVIVSD) and the thickness of the rear wall (LVPWTD) and the right ventricular end-diastolic pressure, while the systolic excursion of the tricuspidal ring plane (tapes) was reduced. A slight decrease in the absolute peak values of both the left ventricle (from -20.9 ± 2.3% to -18.8 ± 2.0%) and the right ventricle (from -22.9 ± 3.6% -21.2 ± 3.0%) could be detected.Global longings occurred. There was a decrease in body weight and an increase in both the circulating highly sensitive troponin I as well as the Pro-B type amino-terminal natriuretic peptide (NT-probnp). The change of the sum of LVIVSD and LVPWTD correlated negative with the percentage change in body weight. The only independent determinant for NT-probnp after training was the systolic pressure of the pulmonary artery.NT-Probnp after training correlated positively with the percentage changes in the right ventricular diameter of Basal (RVBAS) and center of the heart cavity (RVMID) and negative with percentage changes of tapes. Similar correlations with RVBAS, RVMID and tapes were found for systolic pressure of the lung artery. The highly sensitive troponin I after training correlated negatively with the percentage change of the body weight, but was associated with no cardiac parameter.

Do compression stockings bring something?

Effects of Wearing Compression Stockings on Exercise Performance and Associated Indicators: A Systematic Review This systematic review examined the effects of wearing compression stockings under the knee on the training performance (or sports activity) and the associated physiological and perceived indicators. Article in PubMed was searched with the following terms: “graduated compression stockings”;“Compression stockings”;“Graduate compression stockings”;“Compression stockings” combines “performance”, “athlete”, “training”, “training performance”, “fatigue”, “sports” and “recovery”, which gives 1067 publications.After verification for inclusion criteria (eg original studies, healthy subjects, performance analysis), 21 studies were selected and analyzed.

Kidney function in the ultramarathon

Ultramarathon and Renal Function: Does Exercise-Induced Acute Kidney Injury Really Exist in Common Conditions? The study used data collected from Ultra-Marathon runners who completed the 2017 edition of the 120 km long “Infernal Trail”. The samples were collected within 2 hours before the race (start) and immediately after the race (destination). The measurements of serum creatinine, Cystatin C, creatine kinase and urinalbumin were carried out.Acute kidney damage was divided into the Rifle criteria.The “damage risk” has been defined as the increase in serum creatinine or decrease in the glomerular filtration rate of more than 25%.The kidney damage was defined as 2 × serum creatinine or decrease in the glomerular filtration rate> 50%. These two categories of kidney damage were combined to calculate the overall incidence in the target. The glomerular filtration rate was estimated by two methods using the measurement for serum creatinine and the measure of Cystatin C.To define renal damage, urinary biomarker \ [neutrophilic gelatinase-associated lipocaline (NGAL) ] were used. A sample of 24 trapped finishers without the use of non-steroidal anti-inflammatory medicinal products was investigated.Depending on the method used to calculate the glomerular filtration rate, a prevalence of kidney damage was observed from 0 to 12.5%. The biomarkers for kidney damage in urine were increased after the race, but without significant decrease in the glomerular filtration rate.

Body core temperature at Ironman Hawaii

Core Temperature Response During the Marathon Portion of the Ironman World Championship (Kona-Hawaii) The Ironman Triathlon consists of 3.8 km swimming, 180 km cycling and 42.195 km. Thermoregulation reactions play an important role in performance optimization and prevention of injuries. Factors such as environmental conditions such as heat and moisture, training level of the athlete and renative duration can influence thermoregulation.Hyperthermia then occurs when the body core temperature rises above 38.5 ° C. The present study aimed to examine the body core temperature for first-class and well-trained age group triathlets during the Marathon of the Ironman World Cup 2014 at ‘Ironman Hawaii’ under thermal stress conditions. The body core temperature of 15 triathlets (age 36.11 ± 7.36 years, body mass 71.14 7.12 kg, size 179 ± 0.04 cm and fat percentage 8.48 ± 0.85) classified for the Ironman World Cupwas measured with a telemetry system for removable pills before the competition, during the marathon and 60 minutes after completion of the race.The average temperature during the marathon was 24.66 ° C (range 22.44-28.50 ° C). The Body Mass Index (BMI) and the perceived effort (Borg Scale and Visual Analog Scale Pain) were determined before the race and 60 minutes after the event. The times were extracted from their official competition time and in the meantime.The closing time was 10: 06: 56 ± 0: 48: 30 h: min: s. The body core temperature was initially 36.62 ± 0.17 ° C, rose at the end of the competition (38.55 ± 0.64 ° C) and remained increased 60 minutes after the competition (38.65 ± 0.41 ° C). The BMI decreased significantly after the competition (22.85 ± 1.11 compared to 21.73 ± 1.36), while both the perceived effort \ [Borg scale (10.2 ± 1.64 compared to 18.60 ± 1, 67 ] as well as the perceived muscle pain \ [VAS (2.75 ± 1.59 compared to 9.08 ± 1,13 ] after the competition significantly increases. The body core temperature during the competition correlated negative with ranking in the age group, but not with the competition time. High-ranking age group triathlets, which went to the ‘Ironman Hawaii’ under thermal stress conditions, reached a state of hyperthermia during the marathon.After 60 minutes recovery, hyperthermia remained.

The meaning of vitamin D on performance

Impact of Vitamin D on Physical Efficiency and Exercise Performance—A Review A vitamin D shortage in athletes and in the general population seems to be a big problem. The most famous role of vitamin D is the regulation of calcium homopostasis.There is a strong relationship between vitamin D and bone health.In addition, its concentrations are associated with the muscle function and the immune response both in general and a sporting population. The vitamin D mirror is strongly related to the presence of vitamin D receptors in most human extra-skeletal cells. The expression of multiple myogen transcription factors that promote the proliferation and differentiation of muscle cells is caused by the exposure of skeletal muscles to vitamin D. The aim of this overview was to summarize the current understanding of the importance of vitamin D for the training performance and physical performance in terms of analysis of the influence of vitamin D on multiple possible mechanisms.

Hyponatriämie am Spartathlon

Incidence of Hyponatremia During a Continuous 246-km Ultramarathon Running Race The purpose of this study was to examine the incidence of the stress-associated hyponatremia in a 246 km long ultra-marathon. Over a period of two years, 63 male participants in the annual savat sound of Athens to Sparta, Greece, in the data analysis were included. A blood sample was taken from the day before the race as well as within 15 minutes of the race and analyzed on the sodium concentration. During the second year of data collection, blood was also removed on 93 km long checkpoint (n = 29).Size and weight were measured before and after the race. The average competition time of all subjects was 33 ± 3 hours with a range of 23.5 and 36.0 hours. Of the 63-recruited finishers, nine the race began with values that indicate a slight hyponatemia.Seven runners were classified at 93 km long checkpoint with a hyponatremia, three of which had a sodium level with severe hyponatemia. After the race, a total of 41 finishers (65%) developed either a slight (n = 27, 43%) or a heavy hyponatremia (n = 14, 22%). The average change in body weight percentage and serum sodium from the race to after the race was -3.6 ± 2.7% (-2.5 ± 1.9 kg) or -6.6 ± 5.6 mmol × L-1. The serum sodium mirror before the race was not a significant predictor of serum sodium levels after the race, but there was a significant and negative relationship between the change in body weight percentage and the serum sodium concentration after the race.
