Opis:
Introduction: Assessment of exercise tolerance (ET) plays an important role in qualifications for treatment and rehabilitation. Aim: The aim of the study was to assess ET in patients before and after inguinal hernia operations with Lichtenstein method. Material and methods: The cohort study included men with inguinal hernia divided into the study group (SG) (n = 50) and control (CG) (n = 50) undergone the Lichtenstein surgery. Patients from the SG met the criterion of coexistence of cardiovascular and respiratory diseases. Day before and on the second day after surgery, patients performed 6MWT and subjectively rate the exertion according to Borg- RPE- Scale (before, immediately after and 10 minutes after the test). 6MWT distance, Borg scale ratings were analysed. On the second day after surgery 66% of patients from the SG and 58% from the CG did not complete the test. Patients from the SG before (500,07 ± 40,38 m) and on the second day after surgery (243,46 ± 18,18 m) achieved shorter distances compared to the CG (565,93 ± 20,41 m; 249,47 ± 26,66 m), p < 0,001 i p = 0,481. A statistically significant negative correlation between 6MWT distance before surgery and age of the patients was confirmed. Patients who did not develop complications achieved significantly longer distances on admission (p = 0,003 for SG, p = 0,004 for CG). For 6MWT before surgery and 2 days after surgery, patients from the SG showed a significantly higher level of fatigue compared to the CG after the test (before: p = 0,001, after: p = 0,001). Patients form the SG often discontinued 6MWT and less tolerated effort compared to the CG. Hence, 6MWT is useful tool for ascertaining physical capacity and ET.

Opis:
Background In Poland average life expectancy extends, while the number of the elderly who are active in the labor market decreases. Material and Methods The study population consisted of 429 people aged 50–70 years old living in the community of south-eastern Poland. The respondents were divided into 2 study groups: group I – late middle age (50–60 years old) and group II – early old age (61–70 years old). With the use of questionnaires they were given, we obtained their socio-demographic data, assessed their cognitive and emotional state, as their physical activity levels. We used the Tinetti test to assess their gait and balance. Results We did not find statistically significant difference in cognitive functioning between the studied groups (p = 0.109). Moreover, there was no significant relationship between belonging to an age group and suffering from depression (p = 0.06) as well as no major differences were observed in the general level of physical activity in relation to age (p = 0.112). Our study found that most of our subjects, regardless of gender, declared their willingness to continue professional work after reaching retirement age. Conclusions The results of own research did not show significant differences in psychophysical state between people in late middle age and at the beginning of old age. Most of the researched participants declared their willingness to continue professional work. Due to changing demographic conditions, it is becoming an important issue to maintain the highest possible level of professional activity of older people in the labor market in Poland.

Opis:
Helical piles are environmental friendly and economical deep foundations that due to environmental considerations are excellent additions to the variety of deep foundation alternatives available to the practitioner. Helical piles performance depends on soil properties, the pile geometry and soil-pile interaction. Helical piles can be a proper alternative in sensitive environmental sites if their bearing capacity is sufficient to support applied loads. The failure capacity of helical piles in this study was measured via an experimental research program that carried out by Frustum Confining Vessel (FCV). FCV is a frustum chamber by approximately linear increase in vertical and lateral stresses along depth from top to bottom. Due to special geometry and applied bottom pressure, this apparatus is a proper choice to test small model piles which can simulate field stress conditions. Small scale helical piles are made with either single helix or more helixes and installed in fine grained sand with three various densities. Axial loading tests including compression and tension tests were performed to achieve pile ultimate capacity. Results indicate the helical piles behavior essentially depends on pile geometric characteristics, i.e. helix configuration and soil properties. According to the achievements, axial uplift capacity of helical model piles is about equal to usual steel model piles that have the helixes diameter. Helical pile compression bearing capacity is too sufficient to act as a medium pile, thus it can be substituted other piles in special geoenvironmental conditions. The bearing capacity also depends on spacing ratio, S/D, and helixes diameter.

Opis:
The paper presents the results of research on forest soil buffer capacity in selected protected areas. The soil buffer capacity was determined for each soil horizon using modified Arrhenius method. Buffer curves were sketched and soil buffer areas were measured with computer techniques. The date obtained were compared with some soil physical and chemical properties using statistical method. Organic (O) and humus (A) horizons of forest soils demonstrate a greater abilities of buffering alkalines than acids whereas buffer capacity of deeper-lying horizons changes as their physical and chemical properties change. Of the examined types of forest soils, the greatest buffer capacity was found for river alluvial soils. The results of the study indicate that the buffer areas are significantly correlated with pH, hydrolytic acidity, content of organic C, clay fractions, sum of exchangeable bases and cation exchangeable capacity.
W pracy przedstawiono wyniki badań nad zdolnościami buforowymi gleb wybranych obszarów chronionych. Analizie poddano 7 profili gleb leśnych reprezentujących następujące podtypy gleb: mady rzeczne brunatne, mady rzeczne próchnicze, gleby płowe zaciekowe, gleby rdzawe brunatne, gleby rdzawe właściwe oraz gleby bielicowe właściwe. Wykreślono dla nich krzywe buforowe zmodyfikowaną metodą Arrheniusa i zmierzono techniką komputerową powierzchnie buforowe gleb. Uzyskane dane porównano statystycznie z niektórymi właściwościami fizyczno-chemicznymi gleb. Poziomy organiczne (O) i próchniczne (A) gleb leśnych wykazują większe zdolności buforowania zasad niż kwasów, natomiast zdolności buforowe poziomów głębiej zalegających zmieniają się wraz z ich właściwościami fizyczno-chemicznymi. Wśród badanych typów gleb leśnych największe zdolności buforowe wykazują mady rzeczne. Wyniki badań wskazują, że powierzchnie buforowe badanych gleb są istotnie skorelowane z pH, kwasowością hydrolityczną, zawartością węgla związków organicznych, frakcja iłu, sumą zasad wymiennych oraz z kationową pojemnością sorpcyjną.

Background: This study was based on gender differences in male and female trained tennis players. Aim of the study: The aim of this study was to determine the extent that physical training could minimize the gender differences in lung capacities in trained tennis players aged 14–17 years. Material and methods: The participants were ten male and seven female lawn tennis players, with a mean ± standard deviation (SD) age of 15.5 ± 1.27 and 14.43 ± 1.13 years, respectively. Physical characteristics and lung volumes were measured on the same day for each participant. Data were presented as mean ± SD, and Student’s t-test to compare the measured variables was performed. Results: Differences between genders were insignificant in terms of age (years), weight (kg), body fat (%), lean body mass (kg) and chest circumference (cm). However, height (cm), and W/H ratio were significantly (p < 0.05) higher in male tennis players in comparison to female players. Insignificant differences were found for TV (L), SVC (L), FVC (L), FEV1 (L), FEV1/FVC (%), FEF25-75% (L/s), PEF (L/s) and MVV (L/min). The only significant difference (p < 0.05) in lung function measures between male and female trained tennis players was for PIF (L/s). Conclusions: Male tennis players were taller than female tennis players of same age range, which might be advantageous for males while playing. Insignificant differences between male and female players in the various lung variables measured indicated that the influence of height and gender differences could be minimized by proper training during puberty. A significantly higher PIF in male players indicated stronger and more powerful inspiratory muscle activity compared with female tennis players.

Opis:
Rescue operation consists of many connected parts, which are called rescue chain links. The quality of the whole operation depends on the accuracy of execution and compliance with each link. Undue hurry, sluggishness or excessive exhaustion of lifeguard, may decrease the quality of performed resuscitation procedures, which is an important element of the whole rescuing process. The presence of a qualified lifeguard or rescue team is essential to the rescuing process. Situations in which lifeguard is on duty as a single unit are permitted in Polish legal regulations. In such cases, up to the point of transferring the victim to emergency medical services, rescue operation lies in the hands of a single lifeguard. The aim of this report is a comparative analysis of the quality of two-minute CPR procedures performed on QCPR anatomical models (Resusci Little Anne), in case of a one-person rescue operation at the swimming pool. 22 students of Water Safety, University of Szczecin took part in the experiment. The results of the experiment showed that the exhaustion of the lifeguard didn’t have a substantial impact on the quality and effectiveness of the rescue procedures. The study was conducted in conditions isolated from fatigue and after a rescue operation performed in water.

Opis:
Four hundred million adults are obese. Such a pandemic involves people of working age. Excess weight imposes abnormal mechanics on body movements, which could account for the high incidence of musculoskeletal disorders in these subjects. This article reviews the physiological and biomechanical causes of the reduced work capacity in obese workers and speculates on the relationships between occupational exposure and obesity. The reduction in work capacity appears to be due to the following factors: reduced spine flexibility, decay in endurance, limited range of movement of the major joints, reduced muscle strength and capacity to hold prolonged fixed postures, impaired respiratory capacity and visual control. Work capacity in morbidly obese workers should always be evaluated to match specific job demands. Due to the relationship between obesity, musculoskeletal disorders, disability and health costs, prevention of obesity and ergonomic interventions on-site are a priority in the work place.

Opis:
Współczesne badania wskazują na brak pozytywnego wpływu na zdrowie dużych obciążeń fizycznych w pracy zawodowej, zwłaszcza w połączeniu z deficytem aktywności fizycznej rekreacyjnej w czasie wolnym od pracy. Kobiety, ze względu na uwarunkowania fizjologiczne, nie są w stanie wykonywać wszystkich czynności w pracy na równi z mężczyznami. Dotyczy to zwłaszcza prac związanych z wysiłkiem fizycznym i transportem ciężarów oraz wymuszoną pozycją ciała. W przypadku kobiet starszych, oprócz fizjologicznych różnic podyktowanych płcią, dochodzą zmiany funkcjonalne zachodzące w organizmie ludzkim wraz z wiekiem, które również istotnie obniżają możliwość wykonywania pracy fizycznej. Lekceważenie przez pracodawców problemu ciężkiej pracy fizycznej prowadzi do niekorzystnych skutków, zarówno dla pracowników, jak i dla firmy. Nadmierne obciążenie i związane z nim zmęczenie pracownika jest przyczyną gorszej jakości i wydajności pracy oraz zwiększenia absencji chorobowej. Dlatego oczywista wydaje się konieczność dostosowywania stanowisk i warunków pracy do potrzeb pracownic fizycznych w starszym wieku.
Contemporary studies indicate the lack of a positive impact of high physical effort in professional work on health, especially in connection with the deficit of recreational physical activity during leisure time. Women, due to physiological conditions, are not able to perform all activities at work equally with men. This applies in particular to work related to physical effort, transport of weights and forced body position. In the case of older women, apart from the physiological differences dictated by gender, functional changes occurring in the ageing human body, which also significantly reduce the ability to perform physical work, are added. The problem of employers disregarding hard physical labour leads to adverse effects for both them and their companies. Excessive work toad and, associated with it, fatigue of employees result in inferior quality and work efficiency and the increase in sick leave due to ailments and illnesses. Therefore, it seems obvious to adapt the work station and working conditions to the needs of older women that perform physical work.

Opis:
The study objective was to analyse the number of tourists present in the shore zone and bathing areas of lakes with regard to their tourist carrying capacity and the amount of biogenic substances potentially entering the ecosystem from the beach and bathing areas. The procedures from project between the EU and Poland, in the module “Development of the sanitary supervision of water quality” were used in three categories: physiological substances - sweat and urine; water-soluble and insoluble organic compounds; and biogenic elements - nitrogen and phosphorus. The research was conducted in two model mesotrophic lakes, Piaseczno and Zagłębocze, located in the Łęczna-Włodawa Lakeland (eastern Poland). The data were analysed in reference to biological trophic status indices defining the limnological status of lakes in the summer of 2014 and 2016. Analyses of gross primary production of phytoplankton using the light and dark bottles method and the analysis of chlorophyll a concentration were applied using the laboratory spectrophotometric method. The relatively small number of tourists recorded in the shore zone of both lakes did not exceed their tourist carrying capacity, and their potential contribution of biogenic substances to the lake ecosystems was small. Biological trophic indices for both lakes indicated that they had been continually late-mesotrophic for decades. The amount of biogenic substances directly linked to beach tourism usually has a minor effect on the limnological status of mesotrophic lakes. Due to the specific character of lake ecosystems, however, even small amounts of these substances can contribute to the destabilisation of the biocenotic system.

Opis:
The ability to function independently is crucial for successful aging, while an age through the development of involutional changes and risk of comorbidity promotes functional limitations. On average, 20% of people over 70 years of age need help in at least one of the 6 basic activities of daily living. The ability to cope in everyday life is affected by the reduction of physical fitness, sensory impairment and the effects of chronic conditions, falls and injuries. Deterioration of physical fitness is a consequence of muscle mass and strength reduction, impaired neuromuscular function resulted in slowing nerve conduction and reaction time, deterioration of balance, coordination and central transmission. Vision and hearing disorders are a consequence of aging and diseases. Cognition impairment, important for an independence, may be a consequence of degenerative changes in the CNS or dementia. Numerous studies have confirmed the relationship of involutional changes, accompanying diseases, falls and injures with limitations in daily functioning, and maintaining physical activity and implementation of a comprehensive geriatric assessment into geriatric care with an early diagnosis of deficits and implementation of intervention can prevent or delay the disclosure of disability.

Opis:
The aim of this study was to determine what proportion of occupationally active Poles have working capacity that enables them to tolerate hard and very hard physical work. For this purpose physical capacity of 1188 occupationally active subjects (524 women and 664 men), aged 18–64 years was examined. Their maximal oxygen consumption (VO2max) was determined indirectly on the basis of their heart rate during an incremental exercise test on a bicycle ergometer. It was found that hard occupational physical work was an excessive load for almost 40% of men and women. This paper discusses how this load should be decreased with planned, appropriately long rest breaks. The percentage of persons for whom their hard physical work becomes an excessive load increases with age to such a degree that a new assessment of individual capability for such work is recommended for persons over 40 years old.
