Pulmonary edema while swimming

Swimming-induced pulmonary edema: current perspectives With the growing popularity of water sports cases of swimming-induced pulmonary EDEMA (SIPE) are increasingly recognized. Sipe, a potentially life-threatening disease, is an acute cause of respiratory distress at athletes. It has often been described in divers, swimmers and triathlets and is marked after immersion in water through symptoms and signs of pulmonary edema. It is important to know that the symptoms of athletes can have a wide range of light respiratory distress to heavy dyspnea, hemoptysis and hypoxia. In most cases, the symptoms quickly dissolve within 48 hours after leaving the water. Recent progress in understanding the pathophysiology of SIPE, especially with regard to increased pulmonary vascular pressures, have begun to clarify this hard-barred state clearer and to distinguish its predisposing factors. It is important that organizers and athletes know Sipe.Immediate recognition is not only necessary to prevent drowning, but also to carry out adequate medical treatment and subsequent advice regarding the return to swimming and relapse risk.

Body weight during an ultramarathon

Considerations in the Use of Body Mass Change to Estimate Change in Hydration Status During a 161-Kilometer Ultramarathon Running Competition In scientific literature and popular literature, they find indications of hydration that body mass losses of more than 2% should be avoided during the burden. In this work, we show that these guidelines are not applicable to longer loads of several hours, in which body mass loss does not reflect no equivalent loss of body water due to the impact of body mass change due to the substrate application, the release of the muscle-bound water and water. These impact on body mass loss required to maintain the body’s water balance are shown for a 161-km long ultramarathone, using data for total energy costs, exogenous energy consumption and percentage of any energy, the average body mass of the subscriber andUses the extent of the collection of soft tissue fluid during an ultramarathone. We assume that the total energy from proteins is between 5 and 10%. The entire exogenous energy is used to support the energy costs of the race. The glycogen consumption is between 300 and 500 g, the water associated with glycogen between 1 and 3 g per g of glycogen, and the mass of the bladder and the gastrointestinal tract is unchanged from the measurements before the race to measuring the body mass after the race.

Quality of life of vegan runners

Quality of life of female and male vegetarian and vegan endurance runners compared to omnivores - results from the NURMI study (step 2) It is known that health-related effects of a vegetarian or vegan diet support parameters that positively influence training performance in athletes, while the knowledge of psyche and well-being is sparse. The aim of the study was to compare the quality of life of endurance athletes after a vegetarian or vegan diet with those who hold a conventional diet. A total of 281 recreational runners (159 women, 122 men) filled the WHOQOL-BREF questionnaire consisting of physical health, psychic well-being, social relationships and environment and scored on a scale of 4 to 20 points. It turned out that 123 people held a conventional diet and 158 a vegetarian / vegan diet.There were 173 runners who fulfilled the inclusion criteria, including 103 semi-marathon runners and 70 marathon and ultramarathon runners and 108 10 km runners as a control group. The total QOL values were high (\ ~ 16.62 ± 1.91).Men had higher scores as women due to high scores in physical health and psychological well-being. A smaller effect on the RenDistanz was observed in women, where half marathon runners had a higher score than 10 km runners.A moderate interaction diet × RenDistential action on environmental values was shown for men. The results showed that endurance runners had a high quality of life regardless of the RenDistance or the diet.

Influence of an ironman on the testosterone concentration

Evidence of the Exercise Hypogonadal Male Condition at the 2011 Kona Ironman World Championships Earlier research has shown that high volumes of aerobic trainings lead to a reduction in basal testosterone concentrations in men. These previous studies were mainly carried out at leisure runners and identified a reduced testosterone, but no concentrations that were low enough to be considered pathological. Therefore, it was the aim of this study to examine the basal concentrations of testosterone and cortisol in elite triathlets and to evaluate the influence of a World Cup race on the acute reactions of these hormones.22 men (age: 40.6 ± 11.5 years;Size: 179 ± 6 cm; Weight: 77.0 ± 7.0 kg) participated in the Ironman World Championships 2011 served as subjects. Calm blood samples were taken 2-4 days before (BL) as well as immediately (IP), 1 day (D1) and 2 days (D2) after the event and later analyzed on total testosterone and cortisol concentrations. With BL had a normal testosterone concentration of the 22 subjects, while 9 men fell into a “gray zone” and 4 other men showed concentrations that indicate a defect. Testosterone was significantly lower than BL at D1 and D2.Cortisol differed significantly from the starting value at IP. There were significant correlations between time and age as well as output value testosterone and cortisol.

Russians are the fastest 100 km runners in the world

Russians are the fastest 100-km ultra-marathoners in the world A recent study on the top ten over 100 km to nationality showed that Japanese runners were the fastest. This selection of top athletes can lead to selection distortion, and the goal of this current study was to examine where the fastest 100 km runners come from, by taking into account all finishers since 1959 in 100 km runs. We analyzed data of 150'710 athletes, who completed a 100 km run between the years 1959 and 2016. To get precise estimates and plots, we only chose the nationalities with 900 and more placements that led to 24 nationalities.Histograms and density plots were performed to investigate the distribution of the race period. A linear regression analysis by gender, age and year was performed to investigate the competition time between nationalities.Histograms, density and scattering diagrams showed that some nationalities had a time limit of 14 hours. From the complete record, the runs were removed with more than 14 hours (cut record) and the same descriptive diagrams and analyzes as for the complete record were performed again. In addition to linear regression, a shortened regression with the cut record was performed to enable a conclusion for the entire sample. In order to examine a possible difference between races at home and race abroad, an interaction racetrack was included in consultation with nationality in the model. Most finishes were achieved by runners from Japan, Germany, Switzerland, France, Italy and the USA with more than 260,000 (85%) finishes. Runners from Russia and Hungary were the fastest and runners from Hong Kong and China were the slowest.

The age of the best performance in the Duathlon

The age of peak performance in women and men duathletes – The paradigm of short and long versions in “Powerman Zofingen” The age of peak performance was examined in detail in various endurance and ultra-endurance sports;However, there is less information about Duathlon (running, cycling, running). The aim of the present study was to race the age of the peak performance of Duethlen, which run either in a short (10 km, 50 km and 5 km) or a long distance (10 km, 150 km and 30 km).From 2003 to 2017, 6'671 participants (women, n = 1,037, age 36.6 ± 9.1 years; men, n = 5 634, 40.0 ± 10,0 years) were analyzed in “Powerman Zofingen”. Looking at the finishers in 5-year-old age groups, a small main effect of sex on the race time was observed on the short distance, with men (171.7 ± 20.9 min) faster than women (186.0 ± 21.5 min). A small main effect of the age group was shown for the gender, where 20-24 years the fastest and 70-74 years were the slowest age group. No interaction of gender × age group was found.On the long range, a small main effect of gender was observed on the race time, with men (502.8 ± 56.8 minutes) around -7.6% faster than women (544.3 ± 62.8 minutes). A great main effect of the age group on the race period was shown, with the age group for 25-29 years the fastest and age group 70-74 years the slowest. A small sex × Age group Interaction on race time was found with a gender difference from -22.4% (15-19 years) to -6.6% (30-34 years). Due to these findings, a higher age of the peak performance in the Langen was detected in the “Powerman Zofingen” as in the short distance.

Motivation at endurance athletes

Antecedents of exercise dependence in ultra-endurance sports: Reduced basic need satisfaction and avoidance-motivated self-control The initiation and maintenance of sports and motive behavior is usually discussed in health promotion strategies. In the present study, we analyzed a sample of extreme endurance athletes and made us to predict the addiction that is a facet of a sports health risk. We are therefore based on the self-determination theory after which low psychological needs can lead to excessive compensatory behavior. We aim to unravel the effects of the need for the activity in the activity itself (exercise) and outside the activity (work / leisure) to the addiction. In addition, we suggest an anxious self-motivation as a mediator and test whether it connects a low basic need for training with a training dependency.
