Ultramarathon mit Diabetes mellitus

Ultramarathon with Type 1 Diabetes We report on the case of a 63-year-old runner with diabetes mellitus type 1, which has been needed since its 21st year of life. At the age of 32, he completed his first marathon and the first ultramarathon at the age of 34. So far, he has completed more than 90 marathons and ultramarathons. Thanks to an insulin pump and continuous blood glucose measurement, he has previously completed 48 24-hour runs with an average distance of 133 km.

Stress for athletes

Are adolescent elite athletes less psychologically distressed than controls? A cross-sectional study of 966 Norwegian adolescents Mental stresses to teens and groups with other psychic problems such as eating disorders. The aim of this study was to examine the prevalence of mental stress in young competitive sports experts and age-appropriate controls and whether prevalence Perfectionism and eating disorders are due.For this cross-sectional study, first semester came into question from all Norwegian top sports schools (n = 711) and 500 students from randomly selected ordinary grammar schools.A total of 611 athletes and 355 students as controls delivered self-report data on mental stress, perfectionism and esprobyses (body detachment and one urge for leanness) as well as their physical training / activity. A significantly higher proportion of controls was achieved over the cutoff point for pronounced mental stress. Physical activity, which was about the recommended values for this age group, a psychological burden on the controls predicted, while the opposite was found in the elite athlete sample. In both samples, perfectionist concerns said, i. Worry about mistakes, a general mental stress advance. Under the competitors, however, perfectionist concerns were particularly associated with clinically significant mental stress.In addition, the influence of eating disorders was negligible.

Vitamin D and Ultra Marathon

Personality Traits and Vitamin D3 Supplementation Affect Mood State 12 h Before 100 km Ultramarathon Run Participation in extreme endurance sports enjoys increasing popularity, making more people involved. Participation in a 100 km run is associated with a large physiological and mental stress that can influence the reflux. The aim of this study was therefore to find out whether personality, experience and motives for participation associated with the mood and the runner’s changes and whether the supplementation with vitamin D3 influences the mood 12 hours before and 12 hours after the barrel. The subject group consisted of 20 experienced marathon and ultramarathon runners participating in a 100 km run. All participants were men between 31 and 50 (M = 40.75, SD = 7.15). The group was divided into two equal subgroups: the placebo group and the group with vitamin D3 supplements. The personality traits were assessed with the Polish version of Eysicks EPQ-R 106, and the mood states were measured twice (12 hours before and after the barrel), using the Polish version of Mathews, Chamberlain and Jones’s umacl. Motives for participating in ultramarathons were measured with the IPAO of Lipowski and Zaleski. The vitamin D3 mirrors correlated very strongly with the energetic excitement (EA) and strong hedonian tone (HT) for 12 hours before the barrel. There were no significant correlations between vitamin D3 mirrors and reflections after the barrel. In addition, extraversion correlated with tempus excitation (TA) and EA, while neurotizism moderately with Ta and Ht.

Ice miles and their load on the body

Physiological Responses to Swimming Repetitive “Ice Miles” The swimming of so-called ice miles (1 mile swimming in water of 5 ° C and colder) is always greater popularity. Since the founding of the International Ice Swimming Association (IISA) in 2009, official races as a World Cup race and World Championships will be held. Ice swimming was demonstration sport at the 2014 Olympics in Sochi, Russia. This case study aimed to determine the body temperature and selected hematological and biochemical parameters before and after repeated “ice miles”. An experienced ice float completed six consecutive ice miles within two days. Three ice miles fulfilled the strict criteria for the definition of ice miles, while the other three were very close to the temperature limit (5.2, 6.1 and 6.6 ° C). Swimming times, changes in body temperature, and selected laboratory parameters were recorded. The athlete showed a metabolic acidosis after each ice mile (an increase in lactate and TCO2; a decrease in base surplus and HCO3) and an increase in blood sugar, cortisol and creatine kinase. The decrease in pH correlated significantly and negatively with the increase in the cortisol mirror, suggesting that this intensive movement causes a metabolic stress. The change in body core temperature between the beginning and end was negatively associated with metabolic acidosis. The increase in creatine kinase indicates skeletal muscle damage by chills after an ice mile. As a practical consequence for athletes and coach, swimming in cold water during ice miles leads to a metabolic acidosis that tries to compensate for the float with a respiratory reaction. In view of the increasing popularity of ice swimming, the results have a practical value for swimmers and supervisors (eg trainers, exercise physiologists and physicians) working with them, as our results provide a detailed description of acute physiological reactions to repeated swimming in cold conditions.

Pacing at a teenager at a marathon attempt

Pacing of an Untrained 17-Year-Old Teenager in a Marathon Attempt Although there is an increased scientific interest in physiological reactions to endurance training, there is limited information for teenagers who participate in endurance competitions. We report on the case of an untrained 17-year-old female teenager (50.6 kg, 167 cm, Body Mass Index 18.1 kg / m2), which did not want to complete a marathon within 6 hours without preparation. The young woman missed her goal only 2 km.When the average running speed an hour has been analyzed, there was a main influence of the race lesson on the running speed, with the running speed in the fifth hour lower in the second hour. Despite a progressive decrease in running speed, it was still able to start a final spurt, which can be represented by a non-linear regression fourth degree. After five days, the creatine kinase reached the original value and the trash of hemoglobin and hematocrit showed an expansion of the plasma volume. A marathon as a teenager to run the physical health did not affect, especially when a self-dialed pace was chosen. Laboratory parameters during and after running similar changes as they have already been described for adolescents and adults after a marathon. Increased values fell back to the starting value within a few days.

Liquid and food intake in an ultramarathon

Real-Time Observations of Food and Fluid Timing During a 120 km Ultramarathon In this case study, it was about using real-time observations to investigate the timing of ultramarathon runners in food intake and fluid intake per 15 km and per hour and the entire body weight loss due to dehydration. The study included five male ultramarathon runners who were observed during a 120 km long race. The members of the research team followed on a bicycle and continuously watched their food intake with cameras. The hourly carbohydrate intake was between 22.1 and 62.6 g / h and the fluid intake varied between 260 and 603 ml / h. These numbers remained relatively stable during the ultra-endurance marathon. The runners took an average of 3-6 times a 15 km of food and liquid. The runners reached a higher total carbohydrate consumption in the second half of the race, but no higher fluid intake. Energy desire contributed most to the entire average carbohydrate recording. The weight after the race was 3.6 ± 2.3% lower than the weight before the race, resulting in a non-significant but practical relevant difference.

Salt in endurance sports

How important is salt for athletes? In one of the current issues of the Fit for Life ‘, the aspect of the salt feed is discussed.

There are different forms of salt supply. In the last section of the article, a very special form will be described, see https://fitforlife.ch/salz-im-ausendimentreport/?utm_source=newsletter

Knee pain in cyclists

Potential factors associated with knee pain in cyclists: a systematic review The possible factors associated with overload damage and pain in cyclists supported by scientific evidence are still unclear. The present study aimed to determine the most important factors in connection with the overuse of knee pain and / or injury to cyclists on the basis of a systematic search for the latest findings. In the search, a possible mechanism in connection with knee pain or injuries was investigated, which could be used in clinical practice. Databases were searched and studies were included if presented results from original studies. They should preferably include, but not limited to, leisure and / or competitive athletes with or without knee pain. The quality of the item was evaluated.Eleven articles were considered for a full text test. The studies generally included the evaluation of biomechanical results in connection with knee pain in cyclists. Overall, the studies showed that cyclists with knee pain have greater knee adcreation and larger dorsalflexion of the ankle and differences in activation for Hamstring and QuadricePs muscles. Unclear results were observed for kneemoments, and no differences were observed for knee fluid angles, tibiofemoral and patellofemoral forces. It is important to mention that various types of knee pain were mixed in most studies, focusing on two studies on anterior-associated pain. Cyclists with excessive pain or injuries on the knees showed increased media projection of their knees and a changed activation of Vastus Medialis and Vastus Lateralis.

When do the runners specialize in the marathon track?

Marathon Specialization in Elites: A Head Start for Africans This study pursued the evaluation of the differences in event-specific specialization between African and non-frican male marathon runners based on age, performance and career length. For this purpose, the top 90 of the African marathon runners from 2001 to 2015 with the top 90 of non-African marathon runners from the same period over various markers in terms of age, performance and career length compared. It turned out that African marathon runners specialize in excellence and retreat from competitive sports as non-African marathon runners. In addition, African marathon runners were faster in these career periods and in half marathon performance faster. There was no significant difference in the number of marathons between the groups, but African marathon runners ran more frequently than non-African marathon runners. The half marathon performance correlated positively with the marathon performance. Marathon runners specializing in young years showed significantly higher suggestions rates than those specializing in older age groups.
