Vitamin D does not only influence the musculoskeletal health and mineral homeostasis but it also affects cardiovascular, endocrine, nervous, immune mental functions, thus is of considerable importance for both physically active people elite athletes. However, vitamin deficiency common worldwide results from inadequate endogenous skin synthesis (insufficient ultraviolet B exposure) diet. To improve status athletes often travel to lower latitude during winter. The aim study was evaluate...

ObjectivesThe aim of the study was to identify predictors determining course COVID-19 and antibody response in elite athletes.DesignObservational study.MethodsRoutine medical screening with physical examination, resting ECG, laboratory tests including performed 12–68 days after diagnosis 111 athletes different sports.ResultsClinical symptoms were observed 84% subjects. The severity mild 82% moderate 2% cases. Athletes aged above 26 male more likely develop symptomatic COVID-19. Asymptomatic...

Background: Athletes and coaches believe in the ergogenic effect of vitamin B12 (which results from enhanced erythropoiesis) they often insist on its unjustified supplementation. Therefore, our study aimed to assess status Polish elite athletes influence red blood cell parameters. Methods: In total, 1131 samples were collected during six years 243 track field divided into strength endurance groups, as well according declared use injections. Results: An average concentration all subjects was...

ObjectivesTo determine the number of training days lost due to COVID-19 and vaccination against in elite athletes.DesignRetrospective cohort study.MethodsThe questionnaire on impact plans was filled out by 1073 Polish athletes who underwent routine medical screening between September December 2021.ResultsCOVID-19 diagnosed 421 subjects (39 %), whom 26 % were asymptomatic. On 10-point scale, <1 had perceived severity disease above 8, whereas for 64 it 4 or below. Vaccination administered 820...

Background: Little is known about the influence of dynamic training on hemodynamic and neurohormonal responses to static exercise inflammatory markers in optimally treated post-coronary artery bypass grafting (CABG) patients. Methods Results: One hundred twenty male patients, aged 55±6 years, 3 months after receiving CABG, were randomized either 6 weeks aerobic a cycloergometer, times week, at 70-80% maximum tolerated heart rate (HR) (training group, n=60) or control group (n=60). At...

The present study was designed to determine changes in the multiple-choice reaction time (MRT) during treadmill running simulating locomotor activity a soccer game and examine effect of branched chain amino acids (BCAA) ingestion on psychomotor performance effort. Ten male players were submitted BCAA placebo trials at 1-week intervals randomized order. (7 g) or given 1 h before exercise double blind manner. test consisted two 45 min bouts separated by 15-min passive rest period whole ended...

Background: Little is known about the influence of aerobic training on neurohormonal and hemodynamic responses to head-up tilt (HUT) autonomic balance at rest after exercise in optimally treated, low risk post-coronary artery bypass grafting (CABG) patients. Methods: One hundred male patients, mean age 56 &#177; 6 years, 3 months CABG, were randomized either 6-week cycloergometer, times a week, 70&#8211;80% max tolerated heart rate (HR) (training group, n = 50) or control group (n 50).

The preparation of Polish Air Force cadets for survival in isolation is a necessary element their training, to demonstrate just how difficult can be the conditions they could encounter combat situation. Objective. aim research was assess effect long-term training on selected coordination motor skills cadets.Fifteen air force aged 19.6±0.3 years exercised 36 hours during without possibility sleep. They were examined 4 times: Day 1 - before effort (training), 2 after 24 3 directly next day, an...

Abstract The aim of the study was to reveal whether marathon running influences regulators lipid metabolism i.e. angiopoietin-like protein 4 (ANGPTL4), interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α). Plasma concentration ANGPTL4, IL-6, TNF-α lipids were determined in samples collected from 11 male runners before marathon, immediately after run at 90 min recovery. ANGPTL4 increased during exercise 55.5 ± 13.4 78.1 15.0 ng/ml (P &lt; 0.001). This accompanied by a significant increase...

Abstract An aluminium silo with initial imperfections is analysed. Two types of imperfection are considered. The first one takes the form local indentations in shell; their size and range adopted on basis standard guidelines. second type a global described through use its eigenforms by means two‐dimensional random fields. calculations limited to two cases loading: negative pressure wind. choice loading has been suggested Eurocodes. In case wind load, probability distribution direction taken...

Vitamin D is a nutrient whose active form affects tissues as hormone and possibly enhances performance. One plausible mechanism by increasing testosterone concentration, which established an important factor for athletic Therefore the aim of study was to examine relationship between plasma concentration 25(OH)D in Polish elite track field athletes depending on vitamin status, season, training period, body composition, sex, type training, sun exposure supplementation. Plasma concentrations...

Objective: The aim of the study was to evaluate safety and tolerance influenza vaccines for northern southern hemispheres in Polish elite athletes participating Rio 2016 Olympics. Design: Prospective, observational, cohort study. Setting: Institutional level. Participants: Ninety-seven vaccinated only with hemisphere vaccine; 98 received vaccine alone, whereas 39 were both vaccines. Interventions: a trivalent, inactivated recommended 2015/2016 then 2016.

A concept of a beam superelement is suggested as new tool in the static analysis structures made thin‐walled members. This proposal seems to be especially attractive for treating problems where existing one‐dimensional models do not provide proper solutions. class includes, instance, torsion beams with battens and determination bimoment distribution at nodes frames The entire segment warping stiffener or whole node frame modelled shell elements. stiffness matrix such can estimated according...

Our previous study showed that static handgrip caused increases in the plasma adrenomedullin (ADM) both patients with heart failure (HF) and healthy subjects. The present was designed to determine role of sympathetic nervous system mediating ADM changes during HF. Twelve male HF (II class NYHA) treated carvedilol, a non-selective adrenergic blocker (TC) 12 untreated carvedilol (UC) performed two 3-min bouts at 30% maximal voluntary contraction, alternately each hand. At end exercise 5 min...

The importance of thyroid hormone, catecholamines, and insulin in modification the thermogenic effect glucose (TEG) was examined 34 healthy 32 hypothyroid subjects.
