Summary: The process of reconstructing damaged skeletal muscles involves degeneration, inflammatory and immune responses, regeneration and reorganization, which are regulated by a number of immune-endocrine factors affecting muscle cells and satellite cells (SCs). One of these molecules is testosterone (T), which binds to the androgen receptor (AR) to initiate the expression of the muscle isoform of insulin-like growth factor 1 (IGF-1Ec). The interaction between T and IGF-1Ec stimulates the growth and regeneration of skeletal muscles by inhibiting apoptosis, enhancement of SCs proliferation and myoblasts differentiation. As a result of sarcopenia, muscle dystrophy or wasting diseases, the SCs population is significantly reduced. Regular physical exercise attenuates a decrease in SCs count, and thus elevates the regenerative potential of muscles in both young and elderly people. One of the challenges of modern medicine is the application of SCs and extracellular matrix scaffolds in regenerative and molecular medicine, especially in the treatment of degenerative diseases and post-traumatic muscle reconstruction. The aim of the study is to present current information on the molecular and cellular mechanisms of skeletal muscle regeneration, the role of testosterone and growth factors in the activation of SCs and the possibility of their therapeutic use in stimulating the reconstruction of damaged muscle fibers.

The aim of the study was to compare energy expenditure during three amateur athletes trainings, ie. volleyball, badminton and karate. The study was conducted among 36 adults (23 men and 13 women), aged 39 ±8. Polar M400 heart rate monitors with H7 chest strap were used to estimate energy expenditure during selected training sessions. Energy expenditure during badminton (1261 kcal; 631 kcal/h) and karate (1239 kcal; 823 kcal/h) trainings were significantly higher than energy expenditure during volleyball training (868 kcal; 579 kcal/h). Due to the large energy expenditure during single training session, it seems justified to assess both energy expenditure and energy intake among athletes.

Regularna aktywność ruchowa wywołuje szereg zmian adaptacyjnych, zwłaszcza w układzie krążenia i przemianie materii. W licznych pracach na temat pojedynczego wysiłku i wzmożonej aktywności fizycznej pojawia się coraz więcej potwierdzeń ich korzystnego wpływu na kształtowanie funkcji poznawczych. U podstaw mechanizmów związanych z tym wpływem leżą zmiany anatomiczne i funkcjonalne, m.in. zwiększenie przepływu krwi przez mózg, angiogenezy i neurogenezy, objętości istoty szarej w korze czołowej i skroniowej. Wysiłek pobudza wydzielanie czynników troficznych, wśród których dla procesów poznawczych, plastyczności synaptycznej, poprawy szlaków sygnałowych neurogenezy i funkcji naczyniowych kluczowe są czynnik troficzny pochodzenia mózgowego i insulinopodobny czynnik wzrostowy. Aktywność ruchowa wywołuje wzmożoną ekspresję czynnika troficznego pochodzenia mózgowego, co pozytywnie wpływa na procesy energetyczne i aktywuje w mózgu wiele układów energetycznych, które korzystnie modyfikują potencjał synaptyczny przetwarzania informacji ważnych w kształtowaniu funkcji poznawczych. Wysiłek redukuje stan zapalny przez obniżenie we krwi stężenia cytokin prozapalnych, mogących się przyczyniać do rozwoju procesów neurodegeneracyjnych. Redukuje czynniki ryzyka zespołu metabolicznego, a zwłaszcza nadciśnienie i insulinooporność, więc zmniejsza ryzyko wystąpienia zaburzeń czynności poznawczych, poprawia funkcjonowanie mózgu, opóźnia początek i spowalnia rozwój zaburzeń w chorobach neurodegeneracyjnych, a wśród nich w chorobie Alzheimera i chorobie Parkinsona. Za sprawą wymienionych mechanizmów aktywność ruchowa wydaje się niezbędna do zachowania prawidłowych funkcji poznawczych w każdym wieku.

Wstęp: Trening fizyczny uważany jest za czynnik wpływający na parametry antropometryczne i ciśnienie tęt‑ nicze. Twierdzi się, że osoby regularnie ćwiczące mają lepsze wskaźniki składu ciała oraz niższe wartości ciśnienia tętniczego krwi w porównaniu z osobami nieuprawiającymi sportu. Cel: Ocena wpływu regularnej rocznej aktywności fizycznej prowadzonej w szkole sportowej na skład ciała oraz wartości ciśnienia tętnicze‑ go u dzieci 14-letnich (II klasa gimnazjum). Materiał i metodyka: W badaniu wzięło udział 25 dzieci z gim‑ nazjum sportowego. Dzieci badano dwukrotnie w odstępie 12 miesięcy. Analizie poddano zmianę parame‑ trów antropometrycznych, składu ciała metodą impedancji bioelektrycznej oraz wartości ciśnienia krwi. Wyniki: W całej grupie zaobserwowano wzrost wartości centylowych ciśnienia skurczowego krwi (p < 0,05), przede wszystkim u chłopców. W zakresie ciśnienia rozkurczowego nie zanotowano istotnych różnic. Skład ciała zmienił się niekorzystnie u wszystkich badanych – wzrósł udział tłuszczu (13% vs 20%, p < 0,05), a przy‑ rost masy tłuszczowej był wyższy u dziewczynek (6% vs 3%, p < 0,05). Centyl BMI istotnie statystycznie wzrósł w grupie dziewczynek (37 vs 49, p < 0,05), u chłopców nie uległ zmianie. Wnioski: Aktywność fizyczna proponowana przez szkołę sportową nie poprawia stanu odżywienia 13–14-letnich dziewcząt i chłopców, u których obserwuje się istotne zwiększenie w organizmie zawartości tkanki tłuszczowej. Szkolna aktywność fizyczna nie powoduje obniżenia ciśnienia tętniczego wśród młodzieży w wieku 13–14 lat w odniesieniu do norm wiekowych. W zakresie ciśnienia skurczowego w grupie chłopców zaobserwowano nawet wyższe wartości centylowe.

Wysiłek fizyczny oddziałuje na poszczególne układy organizmu człowieka, w tym szczególnie na układ ruchu, krwionośny i oddechowy, neuro-hormonalny, a przez to na funkcjonowanie wielu narządów wewnętrznych. Od wieków prowadzone są liczne badania mające na celu poznanie zmian zachodzących w organizmie na skutek aktywności fizycznej. Zmiany w funkcjonowaniu organizmu poddanemu określonemu wysiłkowi fizycznemu (zarówno statycznemu jak i dynamicznemu) określane są poprzez zastosowanie diagnostyki medycznej, praw fizycznych oraz diagnostyki sportowej. W pracy opisano zmiany, jakie zachodzą w organizmie człowieka w czasie wysiłku fizycznego, w takich układach jak: kostno-stawowy, mięśniowy, krwionośny, czy też oddechowy. Opisano także procesy przystosowawcze organizmu i wykazano korzystne oraz niekorzystne działanie (fizyczne, psychiczne i społeczne) aktywności fizycznej na organizm człowieka. Sklasyfikowano również wysiłek fizyczny w zależności od przyjętych obecnie kryteriów. Artykuł stanowi częściowe podsumowanie zainteresowań naukowych autorów w latach 2014-2015.

Wheat-dependent exercise induced anaphylaxis (WDEIA), caused by sensitization to omega-5 gliadin is an important clinical problem. The study presents an interesting case of WDEIA and highlights the role of component resolved diagnosis and challenge tests in establishing the proper diagnosis. Patient, 55, male, was diagnosed due to recurrent episodes of anaphylaxis, with generalized urticaria, accompanying hypotension and loss of consciousness. The symptoms occurred every 2-3 months. In the course of diagnosis we performed skin prick tests (SPT) with inhalant and food allergens. We also established the concentration of total IgE, specific IgE to Dermatophagoides pteronyssinus, Dermatophagoides farinae, bee and wasp venom, gluten, wheat and rye flour and the level of IgE specific to allergen components using ImmunoCap ISAC. Patient also performed exercise provocation test on an empty stomach and after eating bread. SPT were positive with wheat flour (4/25 mm) and rye flour (4/5 mm). The concentration of allergen-specific IgE against wheat flour (before exercise provocation test) was 0.18 IU/ml and rye flour 1.06 IU/ml, after provocation test 0.18 IU/ml and 1.21 IU/ml respectively. ImmunoCap ISAC reveled elevated level of IgE specific to wheat allergen component rTri 19 (omega-5-gliadin) - 2.4 ISU-E and to timothy nPhl p4 (berberine bridge enzyme) - 2.5 ISU-E. Exercise provocation test on an empty stomach was negative, with no disturbing symptoms. Exercise provocation test after consumption of bread was positive, with hypotension and generalized whole skin urticaria. Based on the clinical history of the disease, results of provocation test and immunological examination, the patient was diagnosed with wheat- dependent exercise induced anaphylaxis.

Physical exercise has a multi-directional impact on immune response mechanisms. Regularly practiced moderate exercise stimulates immunocompetence, whereas repeated intensive exercise may lead to increased susceptibility to infections. Recently, the issue of influence of exercise on immune system has been drawing much interest. This review presents selected aspects of the influence of physical exercise of different intensity upon humoral and cellular, innate and acquired immunity. The issue of chronic low-grade inflammation in the airways and its possible association with airway infection episodes has also been discussed. [ABSTRACT FROM AUTHOR]

Asthma and bronchial/airway hyperresponsiveness are the commonest chronic medical conditions in athletes, especially in endurance sports. Physical exercise per se, as well as some external factors accompanying sport activity, can promote development of the disease and limit physical performance in athletes. Appropriate functional diagnostics of respiratory system allows to confirm diagnosis of asthma, choose the right medications and monitor the treatment. However, antiasthmatic drugs based mainly on beta-2 adrenergic receptor agonists and glucocorticosteroids could be abused as a doping agents. The appropriate treatment of asthmatic athletes in addition to keeping the disease under control and enabling continuation of the sport career should afford athletes a chance to succeed in competition without being suspected of violation of anti-doping rules.

The physical activity is part of a healthy lifestyle. Effect of physical activity on mental sphere is not completely investigated. The impact of physical exercises on psyche is described by three main mechanisms: biochemical, physiological and psychological. The biochemical mechanism describes the effect on the psyche of: endorphins, monoamines (serotonin and epinephrine), phenylethylamine. It also describes the impact of the neurotrophin BDNF on memory functions. The physiological mechanism is related to body temperature. There are 4 main groups of psychological mechanisms: learning and competence, decentralization, interaction, social, cultural and social development. Conclusions. The movement is an essential element of proper mental and physical development of child. Researches show many benefits of regular physical activity. Benefits include: cognitive development, improve mood, increase of motivation and increase of self-esteem. [ABSTRACT FROM AUTHOR]

•Most studies on nasal dilators have used Breathe Right or Nozovent. Both devices dilate the nasal valves, reduce nasal resistance, and improve nasal airflow. • The use of dilators improves airflow most on inspiration, as the valve is stabilised and prevented from collapse. • The response varies greatly between individuals, and can be impressive. • The effect of nasal dilators may be lower in non-Caucasians. • During exercise, nasal dilators delay the onset of oronasal breathing, and can have only small effects on performance thereafter. • Nozovent and Breathe Right can reduce snoring, and improve otherwise obstructed breathing during sleep in selected patients. It is a challenge to find those patients, and one way could be to perform polysomnography with and without nasal dilator. [ABSTRACT FROM AUTHOR]

Background. The Wingate test is used in the evaluation of anaerobic power in professional athletes. The influence of this test on autonomic nervous system (ANS) activity is not fully explained. The aim of the study was to evaluate the influence of such procedure on ANS activity in young healthy athletes. Material and methods. Nine professional runners aged 17 1 years (16-19) were included in the study. The ANS parameters (baroreflex sensitivity — BRS_WBA, short—term heart rate variability – HRV: SDNN, PNN50, RMSSD, TP, LF, LFnu, HF, HFnu, LF/HF and mean HP were analyzed on the basis of 10-minute systolic arterial pressure (SAP) and heart period (HP) records during controlled breathing (0.23 Hz). BRS_WBA, HRV indices and mean HP were analyzed twice: before (examination 1) and within 1 hour after the Wingate test (examination 2). Results. Statistically significant decrease in BRS_WBA in examination 2 in comparison to examination 1 was found: 9.9±3.9 vs 17.8±10.1 ms/mmHg respectively (p=0.038). SDNN, PNN50, RMSSD, HF and HFnu were significantly lower in examination 2 comparing to examination 1 (p<0.05): 94 40 and 65 25 ms, 57 24 and 37 19 %, 109 64 and 62 26 ms, 7085 7241 and 4360 2993 ms2, 79 12 and 65 15 NU respectively. Similar trend was established in mean HP: from 965 121 to 860 74 ms (p<0.05). LFnu and LF/HF increased significantly: 21 12 and 35 15 NU, 0.30 0.23 and 0.62 0.37 respectively (p<0.05). LF did not change significantly during the examinations (examination 1- 1270 7241 and examination 2 -1407 1223 ms2, p>0.05). Conclusions. Extreme anaerobic physical exertion (Wingate test) leads to decrease in parasympathetic activity and to increase in sympathetic activity of ANS in young healthy runners. These changes persist at least one hour after exertion. [ABSTRACT FROM AUTHOR]

Physical exercise belongs to the most common factors causing asthma exacerbations. Presence of postexercise bronchoconstriction, especially among patients without proper anti-inflammatory treatment, may exacerbate asthma inflammation. Recently, a few publications have appeared which show that the combination of proper pharmacological treatment with physical exercise program may have positive influence on asthma, decrease airway inflammation and remodeling.
