Liquid supply in extreme duration

Considerations for ultra-endurance activities: Part 2 - hydration It is not unusual that those participating in extreme duration events develop a different degree of hypohydration or hyperhydration. For extreme athletes, however, it is important to avoid the performance limiting and potentially fatal consequences of these conditions. During short load times, low impact on the relationship between body mass change and hydration status resulted from the body mass loss due to the oxidation of endogenous fuel storage and water, which supports the intravascular volume generated and released by endogenous fuel oxidation in the oxidation of glycogen. However, these effects have significant impact on longer stresses. In fact, the body mass loses significantly more than 2% in some endurance activities in order to avoid hyperhydration.Therefore, the typical hydration guidelines for avoiding more than 2% body mass loss do not apply to extreme duration activities and may possibly lead to hyperhydration.

Nutrition in extreme duration

Considerations for ultra-endurance activities: part 1- nutrition Extreme endurance loads are unique challenges that can be enhanced beyond the fatigue through sub-optimal diet during elevated requirements and impaired gastrointestinal function. The fatigue causes of extreme expenses are multifactorially conditioned. However, mechanisms may include central or peripheral fatigue, thermal stress, dehydration and / or exhaustion of the endogenous glycogen storage. If the extreme duration load is long enough (eg ≥ 10 hours) and the intensity is low enough (eg 45-60% of maximum oxygen uptake), it is bioenergetically plausible that the ketogenic adjustment of the extreme duration load to improve. Conversely, scientific literature has repeatedly shown that daily reception of carbohydrates (3-12 g / kg / day) and carbohydrate absorption under load (30-110 g / h) can improve performance with extreme expenses loads. In view of the gastrointestinal symptoms that are common in extreme expenses, effective prevention and treatment strategies for diet can provide functional, histological, systemic and symptomatic advantages.

The triple crown in swimming

Sex difference in open-water swimming-The Triple Crown of Open Water Swimming 1875-2017 The aim of the study was to compare the swimming services of successful finishers of the ‘Triple Crown of Open Water Swimming’ from 1875 to 2017 and to evaluate the effects of sex, the venue and nationality of swimmers. Data from 535 Finisher in ‘Catalina Channel Swim’, 1'606 Finisher in ‘English Channel Swim’ and 774 finishers in ‘Manhattan Island Marathon Swim’ were analyzed. We have performed various analyzes and adjustments for regression models for all swimmers and the annual top 5 finishers. The effects (gender, event, time, nationality) and interactions (event time) were examined by a multi-variable spline regression model. For all the swimmers we found that women found about 0.06 km / h faster than men and the Australians were 0.13 km / h faster than Americans where the Americans were 0.19 km / h faster than the British and 0.21 km / h faster than the Canadians. When looking at the annual top 5 swimmer we realized that women were 0.07 km / h slower than men and the Australians were not faster than the Americans, but Americans were 0.21 km / h faster than the British.

Passing Am Vasalaf.

A Portrait of Pacing Profile of Cross-Country Skiers in the Vasaloppet 2004-2017 The aim of this study was to influence the performance group according to the competition time (10 groups; <3 h, 3-4h, etc. up to> 12 h) to the pacing in women (n = 19,465) and men (n = 164'454) in’ Vasaloppet ‘from 2004 to 2017 to examine. The speed in the fastest and slowest split was as a percentage of average race speed and the tempo as differential (%) defined between the fastest and slowest split. Women had an area in pacing as men (44.0 ± 10.6% compared to 41.1 ± 12.5%). For women and men, a nearly perfect relationship between the power group and the pacing was observed. In women, a large main effect was observed on pacing, with the smaller area in the group <4 h (22.8 ± 3.3%) and the largest in the group of 10-11 hours (49.2 ± 9.9%) was observed. For men, the corresponding values were 21.6 ± 2.2% (group <3 h) and 51.6 ± 11.2% (group 10-11 h).

When will the first man run the marathon under 2 hours?

How Much Further For The Sub-Two-Hour Marathon? The border of 2 hours for a marathon for men is one of the big sound limits in sports. In this post, we present a mathematical model with which the possible year in which a man could break the barrier of less than 2 hours can be estimated, and also an assessment of when a woman could break the record of the marathon of Paula Radcliffe. Furthermore, we present some aspects (eg physiology, nationality, age, biomechanics, pacing and drafting), which break through the mileage of marathon runners at elite runners and finally the possible characteristics of the man, the 2-hour time, are connected. In summary, it is possible with the results of the developed equations that a male athlete can break through the 2-hour border next decade (with the performance of Nike® Breaking2 1920-2018 \ [NBP ]: Y = 0.0417x2- 14, 18x +3,128; Year 2026; without Nike® Breaking2 1920-2018: Y = 0.045 × 2-15.12 × + 3,194; Year 2027).

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.
