Opis:
The goal of the thesis was to identify and then compare the incidence of muscle imbalance at 3rd grade students in the academic years 2012/2013 and 2013/2014 at EF CPU in Nitra. The object of our monitoring were 78 students in decimal age from 20.21 to 27.58 years. We analyze the overall incidence of muscle imbalance in the two academic years, the frequency of shortened muscles, weakened muscle and movement stereotypies disorder. At the same time we compare identical characteristics among all female students and among male students as well. We examined the muscle imbalance according to method of Janda (1982) modified by Thurzová (1992) for the purpose of physical education. Based on the measurements, we discovered a high occurrence of overall muscle imbalance at every tested subject in both academic periods. We noticed that the occurrence of shortening in shortened muscles was the highest in the first period in m. rectus femoris and in 78.4 % of subjects and next period at m. quadratus lumborum in 82.4 % of subjects. The frequency of muscle weakened was the highest in both periods the extensors of hip joint in 83 % of subjects first period, 85.3 % of subjects of the second period. When movement stereotypies we observed a high incidence of breaches of movement stereotypies in extension in hip joint in both academic years and 83% (2012/2013) and 82.4 % (2013/2014) subjects. Based on the identified results, we can deduce that not only in individuals that lead hypokinetic way of life but also for students who are regularly engaged locomotor activity but no emphasis on thorough compensation tends to develop muscle imbalances.

Opis:
Introduction: The research was aimed at obtaining and extending the findings of the functional state of musculoskeletal system of the research sample of volleyball players, and also the possibilities of influencing the balance exercises in the sports training of athletes. Material and Methods: The research sample consisted of 12 volleyball players (girls) from the Stara Lubovna Volleyball Club. The first measurement was carried out in September 2015. The average decimal age of the volleyball players was 15.76±0.88 years. In the final measurement, which was made after three months in January 2016 and after the application of a targeted program of balance exercises, the average decimal age of the group was 16.09±0.88 years. Results: The initial measurement of the players found a high percentage of functional muscle disorders and the most risky muscles and muscle groups that tend to shorten and weaken in the analyzed subjects. Based on the above, a targeted compensation program of balancing exercises was developed. A significant decrease of the incidence of measured functional muscle disorders to p<0.01 of shortened flexors of the knee, musculus rectus femoris, of weakened abductors of hip joint, deep neck flexors, lower fixators of spatulas and broken motor stereotypes - one leg stand and push up was observed after the inclusion of experimental factor into the training plans actively for a three-month period. We noted a decrease in shortened musculus triceps surae, musculus quadratus lumborum a musculus iliopsoas, of weakened abdominal muscles and of sitting down stereotype on the significance level of p<0.05. Conclusion: Significant conclusions may be drawn from the acquired statistical data: the inclusion of appropriate and regular balance exercises in the training process of young athletes has a positive impact on reducing or eliminating muscle functional disorders of the musculoskeletal system in its individual components - shortened muscles, weakened muscles and impaired movement patterns.

Opis:
The aim of the study was an assessment of isometric torque (IT) values under static conditions and relative torque (RT) for the plantar flexion muscles (PFM) and dorsal flexion muscles (DFM) and their mutual relations in males 5 years after talocrural joint sprain. IT measurements in PFM and DFM were performed using Biodex System 3. Group I consisted of 20 males on average 5 years after the sprain of the talocrural joint. Group II comprised 23 males with no history of talocrural joint injuries. The angles of measurement were: –15° of dorsiflexion (DF) and 0°, 15°, 30° and 45° for plantar flexion (PF) of the foot. In group I, the IT and RT obtained from PFM of involved leg were statistically significantly lower for most of the measured values of foot angle as compared to the contralateral joint and the results of the control group. The increase in the PF angle resulted in the decrease in IT values obtained from PFM, in favour of DFM. The IT values for PFM and DFM depend on the angle of foot and are represented by two different curves.

Opis:
Ultrasound elastography is a revolutionary medical imaging technique, enabling a quantitative and qualitative evaluation of tissue stiffness. This paper presents, based on published evidence, a wide range of possibilities for this method in clinical trials and scientific research. The use of dynamic elastography avoids the undesired influence of force applied to the tissue by the elastograph probe on the information content of the obtained image. In clinical practice, elastography is used to identify and examine the pathological condition of soft tissues (including cancer lesions and tendonitis) and to diagnose neuromuscular diseases. It is also used in scientific investigations as a non-invasive method to study the structure of skeletal muscle, including muscle thickness, fiber length and pennation angle using standard ultrasonography mode; it is also possible to obtain information about physical properties such as stiffness. Ultrasound elastography could also be a useful tool for physiotherapists monitoring the rehabilitation process. Based on the results of these studies, advances in elastographic imaging technology, and progress in biomedical diagnostic methods, elastography is expected to become a common method used in clinical diagnostics and scientific research.

Introduction: The musculocartilaginous complex is a structure composed of cartilaginous, osseous and muscular elements, which is located at the thoracoabdominal junction, at the level of the right costal arch. Aim: To determine the ultrasonographic characteristics of this complex under normal conditions as well as to demonstrate its effects on the liver depending on the constitutional body built, respiratory phase and patient’s body position. Materials and methods: All abdominal ultrasound scans were performed between 2006 and 2015. A total of 1000 patients (566 females and 434 males aged between 35 and 82 years, mean age 52 years), who had no significant upper abdominal pathologies identified based on clinical and imaging data, were enrolled for the analysis. In addition to standard internal organ assessment, we also attempted to identify the symptoms of hepatic compression by the musculocartilaginous complex. We used 3–6 MHz convex and 7–12 MHz linear transducers. The degree of musculocartilaginous compression of the liver was assessed during breathing in supine and sitting position, as well as with trunk inclined forward. Results: The study showed that musculocartilaginous compression of the liver mostly affects females (96%) with leptosomatic body build. The complex compressing the liver shows a heterogeneous echostructure. Increased hepatic compression was observed during exhalation, in a sitting position and with trunk inclined forward. Conclusions: Cartilaginous compression of the liver depends on body built and patient’s body position. The musculocartilaginous complex may cause focal or segmental compression of the hepatic parenchyma, causing pain in the right upper abdomen in some patients.
Wprowadzenie: Kompleks chrząstkowo-mięśniowy to struktura składająca się z elementów chrzęstnych, kostnych i mięśniowych, zlokalizowana na pograniczu piersiowo-brzusznym, na poziomie prawego łuku żebrowego. Cel: Określenie ultrasonograficznych cech tego kompleksu w warunkach prawidłowych oraz wykazanie jego wpływu na wątrobę w zależności od budowy konstytucjonalnej, fazy oddechowej oraz pozycji przyjmowanej przez pacjenta. Materiał i metoda: Wszystkie badania ultrasonograficzne jamy brzusznej przeprowadzono w okresie od 2006 do 2015. Do analizy zakwalifikowano 1000 osób (566 kobiet i 434 mężczyzn, w przedziale wiekowym 35–82 lata, średnio 52 lata), u których na podstawie danych klinicznych i obrazowych nie stwierdzono istotnych zmian w narządach nadbrzusza. W badaniach ultrasonograficznych jamy brzusznej, oprócz standardowo ocenianych narządów wewnętrznych, skupiono się na poszukiwaniu objawów ucisku wątroby przez kompleks chrząstkowo-mięśniowy. Do badań wykorzystywano głowice konweksowe o częstotliwości 3–6 MHz oraz liniowe o częstotliwości 7–12 MHz. Stopień ucisku wątroby przez kompleks chrząstkowo-mięśniowy oceniano w trakcie oddychania, w ułożeniu pacjenta na plecach, w pozycji siedzącej i w przodopochyleniu tułowia. Wyniki: Wykazano, że ucisk chrząstkowopochodny wątroby dotyczy głównie kobiet (96%) o budowie leptosomicznej. Uciskający wątrobę kompleks najczęściej wykazuje heterogeniczną echostrukturę. Większy stopień ucisku wątroby występował w trakcie wydechu, w pozycji siedzącej i w przodopochyleniu tułowia. Wnioski: Ucisk chrząstkowopochodny wątroby jest uzależniony od budowy ciała oraz przyjmowanej przez pacjenta pozycji. Kompleks chrząstkowo-mięśniowy może wywierać ucisk ogniskowy lub odcinkowy na miąższ wątroby, powodując u części osób ból w prawym nadbrzuszu.

Opis:
Myogenesis, or the formation of muscle tissue, is an extremely complicated process, is essential for the proper functioning of the body. Depending on the type of muscle, they play different important functions. In vertebrata skeletal (striated) muscles allow skeletal movement (locomotion) and maintaining posture. They are built of long, cylindrical cells (myofibres) with numerous nuclei. Each myofibre is composed of many alternately oriented fibrils, resulting in a conspicuous banding. These striated muscles contract quickly and fatigue rapidly. Their development and regeneration are controlled by many genetic factors and some of the most important ones are myogenic regulating factors (MRF), including MyoD (or Myod1), myogenin, Myf5 and MRF-4. These proteins regulate the activity of many genes involved in development and regeneration of muscle tissue. They act in a complementary manner and numerous studies show they are expressed to varying degrees. The synthesis of non-functional or abnormal MRFs may lead to serious consequences and even death due to abnormal development of muscle tissue. MRF-regulated inhibition of myoblasts in their growth cycle is a crucial step in muscle formation.

Opis:
In an adult human, on average, muscles constitute about 40% of their body mass. They are the basic structural and functional elements of the musculoskeletal system based mainly on shrinkage of their fibres. This state, among others, ensures and induces motor reactions defined in a given situation, affects balance and muscle balance, the efficiency of neuromuscular connections, and also decides the efficiency of the motor system. The aim of the work was to review literature regarding the impact of treatments using vibrational stimulus on human muscle tissue. Particular attention was paid to the observed improvement of its motor properties after the completion of t vibrational therapy application. An attempt was also made to present the widest possible use of vibrational procedures in various disease states related to the functionality of muscle tissue, which is why in the present overview, the included research was differentiated in terms of target groups and investigated muscles. The analysis included domestic and foreign literature, in which the positive effect of vibrational treatments on the motor properties of adults was discussed. Studies were selected, the authors of which described the most important parameters of the vibrational stimulus used, such as: frequency, amplitude and duration of exposure. Research work from the last 15 years has been analysed (not including the historical part). However, as many as 70% of the studies referred to have been published in the last 5 years. Data from the following databases was analysed: Medline, Embase, Cochrane CENTRAL trials register, ScienceDirect, PubMed, IEEE Xplore, Wiley Online Library. Key words used: muscles, force, vibration, WBV. Numerous reports indicate the positive effect of vibrational therapy on human muscle tissue. These treatments, among others, prevent muscle atrophy, and in this way, improve or reproduce the lost motor skills of the investigated people. Treatments with the use of vibrations can be performed by the patients themselves without special supervision, the devices that trigger them are easy to use and do not require significant physical effort, which is an undoubted advantage for the elderly and ill patients as well as athletes during the restitution period. It seems wise that any future research regarding the possibility of use of using vibrations in various disease states, including covering the broadly understood pathology of the musculoskeletal system, should focus on the development of optimal parameters and conditions for the use of vibration treatments, associating them with selected disease entities, developing indications and contraindications for their use, as well as determine hypotheses of the effectiveness of undertaken activities and their scientific verification.

Wstęp: U dorosłego człowieka mięśnie stanowią średnio około 40% jego masy ciała. Są podstawowym elementem strukturalnym i funkcjonalnym układu mięśniowo-szkieletowego opartego w głównej mierze na kurczliwości ich włókien. Taki stan rzeczy między innymi zapewnia i wywołuje określone w danej sytuacji reakcje motoryczne, wpływa na zachowanie równowagi i balans mięśniowy, sprawność połączeń nerwowo-mięśniowych, a także decyduje o wydolności układu ruchu. Cel pracy: Celem pracy było dokonanie przeglądu piśmiennictwa, dotyczącego oddziaływania zabiegów z wykorzystaniem bodźca wibracyjnego na tkankę mięśniową człowieka. Szczególną uwagę zwrócono na zaobserwowaną poprawę jego właściwości motorycznych po zakończeniu terapii wibracyjnej. Podjęto także próbę przedstawienia możliwie, jak najszerszego zastosowania zabiegów wibracyjnych w różnych stanach chorobowych związanych z funkcjonalnością tkanki mięśniowej, dlatego uwzględniono w prezentowanym przeglądzie badania zróżnicowane pod względem grup docelowych oraz badanych mięśni. Materiał i metody: Analizie poddano piśmiennictwo krajowe i zagraniczne, w którym zostało omówione pozytywne działanie zabiegów wibracyjnych na zdolności motoryczne dorosłego człowieka. Wybrano badania, których autorzy podawali najważniejsze parametry zastosowanego bodźca wibracyjnego takie jak: częstotliwość, amplituda i czas ekspozycji. Analizowano prace z przestrzeni ostatnich 15 lat (nie wliczając części historycznej). Jednak, aż 70% przywołanych badań była opublikowana w ciągu ostatnich 5 lat. Dokonano analizy przedmiotowych danych w następujących bazach: Medline, Embase, Cochrane CENTRAL trials register, ScienceDirect, PubMed, IEEE Xplore, Wiley Online Library. Słowa kluczowe, jakie użyto to: mięśnie, siła, wibracja, WBV. Podsumowanie-Wnioski: Liczne doniesienia wskazują na pozytywny wpływ terapii wibracyjnej na tkankę mięśniową człowieka. Zabiegi te między innymi zapobiegają zanikowi mięśni, a na tej drodze poprawiają lub odtwarzają utracone zdolności motoryczne badanych osób. Zabiegi z wykorzystaniem wibracji mogą być wykonywane przez samych chorych bez szczególnego nadzoru specjalistycznego, urządzenia je wywołujące są proste w obsłudze i nie wymagają znacznego wysiłku fizycznego, co jest niewątpliwą zaletą dla osób starszych i schorowanych oraz sportowców w okresie restytucji. Wydaje się celowym, aby ewentualne przyszłe badania dotyczące możliwości wykorzystania wibracji w różnych stanach chorobowych, w tym obejmujących szeroko rozumianą patologię układu mięśniowo-szkieletowego, skoncentrować na opracowaniu optymalnych parametrów i warunków stosowania zabiegów wibracyjnych, skojarzenia ich z wybranymi jednostkami chorobowymi, opracowania wskazań i przeciwwskazań do ich wykorzystania, a także ustalenia hipotez efektywności podejmowanych działań oraz naukowej ich weryfikacji.

Objective: The aim of this study was to verify the influence of a specific exercise program on the strength and resistance levels of lumbar flexors and extensors in warehouse workers. Materials and Methods: The population used in this randomized controlled trial included 557 warehouse male workers from a food distribution company in Oporto/Portugal. Upon the application of the selection criteria, 98 workers deemed eligible were randomized in two groups: 57 were assigned to the intervention group and 41 to the control group. The intervention included 9 easily-executed exercises to promote stretching and strengthening of the lumbar region, to be executed daily, at the beginning of the working time, at the company facilities and lasting 8’. Trunk muscles’ voluntary strength and resistance were measured using an isometric electronic dynamometer (Globus Ergometer, Globus, Codigné, Italy) at baseline and eleven months after implementing the exercise program. The data was analyzed using SPSS®, version 17.0. Results: After implementation of the exercise program, in the intervention group, all variables increased, significant differences were observed as for the muscle strength and resistance values (p = 0.014 and p = 0.006, respectively), as well as in the ratio extensors/flexors (p = 0.037). In the control group, all variables decreased, with a statistically significant decrease of the trunk flexors strength level (p = 0.009). Conclusion: The results of this study suggest that a specific exercise intervention program can increase trunk extensors strength and resistance.

Opis:
The research aim was to evaluate the levels of contamination with fluorine compounds in selected tissues of laying hens kept in a free range system in Central Pomerania (Poland) in relation to the distance from contaminant emission sources. The study covered 60, randomly selected, two-year-old laying hens on 6 farms. Fluorine levels in tissues of laying hens were determined with the potentiometric method using an ion-selective electrode from ORION. The results for the tissues and organs, such as pectoral muscles, livers and breastbones, were investigated with an analysis of variance, the Tukey’s test and linear correlation coefficients. The analyses revealed a higher mean fluorine compound content in the pectoral muscles, livers and breastbones of laying hens in zone 1, located 50 km to the west of the contaminant emission sources, than in zone 2, situated between 80 and 100 km to the west of the pollution sources. Fluorine compound levels in the pectoral muscles of zone 1 birds were almost twice as high in hens from experimental zone 2 (respectively: 1.835 mg kg-1 of DM and 0.978 mg kg-1 of DM). A statistically significantly higher average content of fluorine compounds (4.92 mg kg-1 of DM) was found in the liver of laying hens in zone 1, nearer to the sources of fluorine compounds emission compared to zone 2 (3.34 mg kg-1 of DM). The mean fluorine compounds content in the breastbones of hens in zone 1 was more than 4 times as high as the level of this element identified in the bones of hens kept in zone 2 (respectively: 765 mg kg-1 of DM and 183 mg kg-1 of DM). A significant positive correlation was confirmed between fluorine compound levels in the breastbones and pectoral muscles. The lower level of fluorine compounds in the examined tissues of laying hens in zone 2 could have been influenced by the dominant west and south wind, which limited the spread of pollution. This may also be due to the lower level of fluorine compounds in soil and feed for laying hens in this zone determined in previous studies. The study showed that the closer the sources of emissions of fluorine compounds, the more fluoride in hard tissues of hens’ bodies.

Opis:
Introduction: Isometric and isokinetic dynamometers are mainly used for assessment of strength and endurance of core muscles. However, muscle power represents a more appropriate variable for evaluating of athlete performance that involve dynamic movements of the trunk. This study estimates test-retest reliability of trunk rotational power and velocity over a 1-week interval using the FiTRO Torso Isoinertial Dynamometer. Material and Methods: A group of 32 physically active men performed 5 trunk rotations to each side while seated with a barbell of 1 kg or 20 kg placed on their shoulders. Results: Results showed that assessment of peak and mean velocity in the acceleration phase of trunk rotations with 1 kg provides reliable results (ICC = 0.94 and 0.92 respectively, SEM = 7.0% and 7.3% respectively). However, peak and mean values of velocity and power obtained during trunk rotations with a weight of 20 kg should be interpreted with caution (ICC < 0.80, SEM > 10%). Conclusions: Such an assessment of trunk rotational power and velocity can be used in practice, however with a limitation of performing trunk rotations in a seated position and using lower loads.

Opis:
Introduction: Breathing involves respiratory muscle activities by recruiting motor units. The obstructive and restrictive lung diseases were categorized based on spirometric measurement. Measurement of respiratory muscle function is important in the diagnosis of respiratory disease or dysfunction. Purpose: This study focuses on the involvement of motor units in diaphragm, external intercostals and latissimus dorsi muscles during voluntary contractions in young boys having obstructive and restrictive lung diseases. Materials and methods: Fifty eight young male (14-20 years) were participated and they were grouped into three (normal, restrictive and obstructive) according to their lung condition measured by Spirometry. One way ANOVA was done to understand the significant differences between the muscles of three groups. Involvement of motor unit was shown by plotting the Line diagrams. Mean and standard deviation along with one way ANOVA were calculated in case of three respiratory muscles (External intercostals, Diaphragm, and latissimus dorsi) for three groups. Results: No significant differences were found among three groups during performing Forced vital capacity (FVC), Slow vital capacity (SVC), Maximum voluntary ventilation (MVV), and Minute ventilation (MV). Line diagram shows that during FVC, SVC, and MVV responses of different muscles are higher in three different groups except during MV. Conclusion: This study states that motor unit involvement is different in the case of three different conditions. It can be concluded that restrictive and obstructive diseases might not be interpreted on the basis of only spirometric measurements in static and dynamic lung conditions. Motor unit activation and responses of major respiratory muscles were important determinants during spirometric measurements

Introduction and aim. Rheumatoid arthritis is a chronic progressive systemic disease of the connective tissue affecting the joints, mainly small, of the erosive-destructive polyarthritis type, and frequent systemic inflammatory damage to internal organs. The purpose of the research is to evaluate the effectiveness of physical therapy on the muscles of upper limbs in patients with rheumatoid arthritis by the dynamics of muscle strength and strength index. Material and methods. To determine the strength of the muscles of the affected upper limbs were used dynamometry, calculated strength index as a percentage to assess the functional ability of the affected limb. All patients were divided into control (n=92) and main (n=96) groups, taking into account the functional insufficiency of the joints. Results. After 6 months of physical therapy, muscle strength indicators in the main group of patients with 1st degree of functional joints insufficiency (FJI) in the affected right limb increased by 3.1 kg, in the left by 3 kg; with 2nd degree FJI – in the right limb by 4.2 kg, in the left – by 3.7 kg, significantly exceeded the same indicators in patients of the control group (р<0.05). Similarly, there was an increase in the strength index in the patients of the main group. Conclusion. Physical therapy technology has been developed and implemented effectively influenced the increase in muscle strength and strength index of affected upper limbs of the main group of patients with rheumatoid arthritis.
