Introduction The foot plays an important role as a static-dynamic foundation of the skeleton. The process of the most intensive formation of the foot during the posturogenesis falls on the preschool age and early school age. The aim of the study was to characterize the arch of the feet in children at the age of 5 and to look for the dependence of their arching condition on the Cole’s index level. Material and methods Forty-four preschool children took part in the research. The Cole’s index showed an underweight, normal body weight, overweight and obesity. The plantography method was used to assess the arching of the feet Results Over half of the examined children had normal body weight. Underweight was more common in the boys group, while overweight and obesity in girls. Ninety percent of children had abnormal longitudinal and transverse arches in both feet. The varus of the big toe and the valgus of the small toe was observed in both groups. The position of the heel was set correctly in majority of the participants. Conclusions No relationship was found between the Cole’s index and longitudinal arches of the right and left foot in boys, as well as in girls. The results revealed that excessive body weight in girls was correlated with flattening of the transverse arch and incorrect position of the heel in the right foot. No significant correlation was found between the Cole’s index and the assessed parameters of the foot in boys.

It seems to be common sense, that hypomobility is an essential cause for overweight and adiposity. As a consequence, physical activity usually is recommended against adiposity. In literature doubts, based on empirical studies, could be found, that the lamentations about an unfit and by this fat youth seems to be rather a sociological phenomenon of an imaginary crisis than an empirically based fact.Especially concerning young people in Germany, physical inactivity is accused to be an important cause of adiposity. Therefore we are interested in the spontaneous intensity of physical activity of pupils during their physical education and in leisure time in relation to their body mass index.Pupils (10-19 y old, 15 forms) were observed during their physical education systematically regarding quantitative and qualitative items. Additionally the intensity of physical and sporting activities in leisure time were investigated by questionnaire. The results show, that the rate of underweight was higher than of adiposity in the researched group. Between the intensity of physical activity in physical education and in leisure related to the deviations of normal weight (BMI) no relevant correlations could be stated.Discussing these results, the hypotheses: Physical inactivity is a central cause of adiposity and physical activity is a very good action against adiposity seems to be too simple. Eating behaviour, genetic disposition, psychological factors etc. obviously are very relevant, too. This must be considered in public recommendations against adiposity as well as the risks of uncontrolled physical activities for joints, bones and muscles especially in case of overweight.

The purpose of this study was to assess the physical characteristics of soccer players according to playing level and position. A total of 305 professional male soccer players [Turkish Super League (SL) (n = 161) and Turkish First League (FL) (n = 144)] were involved in this study. All data were gathered at the beginning of preparatory period of mid-season. Height, weight, flexed and tensed upper arm and calf girths, humerus and femur biepicondylar breadths, and four skinfold thicknesses (triceps, subscapular, supraspinale, and medial calf) were measured. Somatotypes were estimated using the Heath-Carter method. SL players were older (p≥0.002), and heavier (p≥0.007) than FL players, while height (p ≤ 0.497) was similar between SL and FL groups. There were significant differences for BW (p≥=0.000), and height (p≥0.000) between playing positions. Goalkeepers were taller (p≥0.000), and heavier (p≥0.001) than other players. Midfielders were shorter (p≥0.013) than other players, however, they were lighter than forwards (p≥0.008). The mean somatotype of the overall players was 2.4-4.8-2.3 (0.9-0.8-0.7) in SL and was 3.0-4.5-2.6 (0.9-0.9-0.8) in FL. SL players were more mesomorphic (p≥0.01), less endomorphic (p≥0.000), and less ectomorphic (p≥0.001) than FL players. Except for goalkeepers, there were significant differences in paired means between whole somatotype means of the SL and FL according to playing positions. The results of the present study demonstrate that both physical characteristics and somatotype of players were significantly different between playing levels and positions. Although the somatotype of soccer players in both levels was dominated by the mesomorph category, players at the higher playing level were more mesomorphic, and less endomorphic and ectomorphic than players at the lower level at all playing positions.

A newcomer to the Baltic Sea, the Chinese mitten crab is especially abundant in the Szczecin Lagoon (NW Poland), where it was first reported in 1927. Body weight, and carapace width and length, were studied in 647 individuals collected with fyke nets in the Szczecin Lagoon from 30 March-18 April 2001 and from 5-21 November 2001. 51.01 of the 543 autumn specimens were males, but only 30.97% of the 113 spring specimens were males. Body weight varied from 45.1 to 306.5 g, carapace length from 41.07 to 81.02 mm and carapace width from 46.68 to 88.85 mm. The autumn crabs were significantly heavier than the spring specimens.

Purpose. In this study, the effect of added weights on the various force and time related characteristics of vertical ground reaction force (VGRF) during the last five steps prior to walk-to-run transition was studied. Basic procedures. Experimental set up consisted of a force platform embedded treadmill. Sixteen college students performed experimental trials by carrying 0%, 10%, 20% and 30% of their body weight. During each trial, after walking for about 30 seconds the speed of the treadmill was increased manually at a rate of 0.089 m/s/s (0.2 miles/hour) until the participant started running. Main findings. A significant interaction (weights × steps) was observed for the first peak of VGRF. The trough, second peak, impulse, and rate of force development of VGRF increased with added weights. During the last five walking steps, most of VGRF parameters changed in a nonlinear fashion. Conclusions. Based on the behavior of VGRF parameters and manually recorded preferred transition speed values, we argue that the added weights would reduce the walk-to-run transition speed. We further speculate that a combination of transition determinants actively participate in the reorganization process during the last five walking steps, prompting the gait transition.

The aim of this study was verification whether an 8-week-long swimming exercise training would induce adaptive changes in body weight in rats and whether possible changes would depend on aquatic environment temperature and animal sex. The exercisetrained groups swam 4 minutes a day, five days a week during eight week of housing. Exercise was performed by swimming in glass tanks containing tap water maintained according to group at 5 ±2°C (cold group) and 36 ±2°C (thermal neutral group). Before and after each week of the experiment, rats were weighed. When comparing the nature of changes in the body weight of rats exposed to swimming exercise training in cold water, attention should be paid to their dependence on sex. There were statistically significant changes in the nature of changes in body weight between male rats and female rats of the cold group (5°C) as early as experimental week 2 until the end of the experiment (p < 0.001). Interestingly, the females exposed to swimming exercise training at 5°C were the only group in which an increase in body weight occurred during experimental week 8 in relation to baseline values.

Selected biological and morphometric characters of two populations of the non-indigenous Chinese mitten crab, one from the Szczecin Lagoon (SL) and the other from San Francisco Bay (SFB), both sampled in autumn, were analysed. The SL crabs showed a significantly higher individual weight, length and carapace width. Males accounted for 55% (87 individuals) of the 179 SL crabs, and 62.9% (90 individuals) of the SFB crabs. Statistical analysis of metric characters, expressed as a percentage of carapace width (X2), enabled four diagnostic characters to be identified: abdomen width (X11), carapace height (X3), left claw length (X7) and carapace length (X1). These jointly explain 71.75% of the differences between the SL and SFB crabs and are indicative of the distinctness of the populations.

Introduction: Obesity is an unfavorable state of health as a result of which come in the initial adaptation, that could gradually transform into specific disease condition. Objectives: The aim of the study was to assess the degree of middle-aged men adaptation to obesity in terms of somatic changes, exercise capacity and cardiopulmonary fitness. Materials and Methods: The study involved 12 obese middle-aged men (OG) - BMI = 34.32 ± 4.11 kg/m2. The control group (CG) consisted of 12 non-obese middle-aged men- BMI = 23.72 ± 1.83 kg/m2,with similar body height (BH) to OG. After recording somatic and physiological data at rest, participants were subjected to the bicycle ergometer test (BT) gradually increasing intensity. During the BT aerobic power (AP) was recorded and analyzed along with parameters characterizing the efficiency of the circulatory and respiratory systems at anaerobic threshold (AT) and the maximum load (ML). Results: This study has shown that obese men have a higher body mass (BM), a higher content of fat (BF), an increased lean body mass (FFM) and a higher content of water (TBW) than CG (p <0.001). Absolute and relatively expressed in relation to the FFM respondents’ values of AP and VO2 were similar in both groups and after taking under the consideration the body weight, they were significantly lower in OG than in the CG. Furthermore, adverse effects have been observed that emerged on some cardiovascular and respiratory variables at rest in case of OG; these effects did not occur during physical exertion. Conclusions: Beyond negative changes occurring obesity in the first stage led to favorable somatic adaptation that entails an increase of FFM in OG, which gives a positive impact on the capacity of physical work of obese men and produces a beneficial effect on the resulting compensation impairment in the respiratory and circulatory systems of these subjects.

Purpose. The aim of the study was to develop a mathematical model to determine correlations between selected somatic traits and indoor rowing test results over a distance of 500 m as well as differences in the level of motor fitness of students of the University of Warmia and Mazury in Olsztyn. Material and methods. The research was carried out on a group of 274 full-time UWM students with the aid of Concept II Indoor Rower. The analysis concerned the effects of students' body weight and body height, year of study and the time required to cover the distance of 500 m during an indoor rowing test. Analysis of variance and regression analysis with stepwise elimination of the polynomial degree and form were used. Results. Only 15 subjects (5.5% of the sample) achieved the highest level of motor fitness, i.e. covered the distance under 92.7 s. A mathematical model describing the effects of decisive variables on the dependent variable was a model of regression of multiple variables of the 2nd degree. The exogenous variables were subjects' body height and body weight. Conclusions. The proposed mathematical model of regression of multiple variables of the 2nd degree can be useful for selection of individuals with predispositions to practice rowing at the academic and recreational levels. The proposed method of mathematical model development should be regarded as an algorithm for other, more versatile models involving additional variables.

Diagnosis of lung cancer (LC) has been fraught with difficulty and by the time of definitive diagnosis, most patients are in later stages of the disease. Epidemiological studies have demonstrated that lifestyle behaviors play an etiological role in LC risk; however data in the literature on this topic often appears inconclusive or require further study. Understanding of the mechanisms operating between lifestyle patterns and their impact on LC is important for the disease’s prevention and treatment. The purpose of this study was to review the current evidence on the role of diet, body mass index (BMI), physical activity, smoking, alcohol consumption, and sex hormone use in LC development based on meta-analyses, systematic reviews and previously published epidemiologic studies. Regarded as the foremost cause of LC, evidence from studies have indicated that tobacco smoking causes LC. Additionally, exposure to outdoor air pollution and/or occupational-related exposures increase LC risk. Further, frequent consumption of red meat, processed meat increases adenocarcinoma and squamous cell carcinoma. Inverse associations between the disease risk and BMI ≥25 kg/m2, higher level of physical activity, and fruit and vegetable consumption with a high frequency were reported. Future studies are warranted to validate the association between histologic subtypes of LC and lifestyle patterns.

Searching of new methods for enhance of food quality, and extension of its shelf-life, in food industry various additives are used. Sodium benzoate is a widely used as food preservative for extending shelf-life of sauces, ketchups and soft drinks. Sodium citrate is applied as a acid regulator, stabilizer or an antioxidant. Usually it is added to jams, jellies, cheeses, and sausages. Both additives are often used simultaneously. The fruit fly (Drosophila melanogaster) can be used for studies confirming safety of additives for food. In experiments the wild tribe of Drosophila melanogaster was used. The influence of two doses of sodium benzoate (E211) and sodium citrate (E331) added simultaneously to feed of fruit fly on its biology were investigated. Two concentrations of the feed additives were tested - lower: 0.8 mg o kg-1 of (E211), and 2.0 g kg-1 of E331, and higher: 1.6 mg kg-' of E211 and 4.0 g kg-' of E33. Simultaneously added to feed sodium benzoate (E211) and sodium citrate E331 (at doses: 0.8 mg o kg-' and 2.0 go kg-', and 1.6 mg . kg-' end 4.0 go kg -', respectively) had no effect on fertility in most of studied generations of wild tribe fruit fly. Used doses of E211 and E331 had no influence on population of most generations of fruit fly too, as well as on body weight of males and females. Only in two generations number of females and males was higher than in control population. Studied additives have no effect on inheritance of wild tribe of Drosophila melanogaster.

W poszukiwaniu nowych metod technologicznych, pozwalających na podniesienie jakości produktu oraz przedłużenie jego trwałości, w przemyśle spożywczym stosowane są dodatki do żywności. Warunkiem stosowania danego dodatku do żywności jest stwierdzenie braku jego wpływu na zdrowie konsumentów. Wydaje się, że muszka owocowa (Drosophila melanogaster) może być dobrym obiektem dla prowadzenia tego typu badań. Celem przeprowadzonych dwuletnich eksperymentów była ocena wpływu benzoesanu sodu (E211) i cytrynianu jednosodowego (E331) na biologię dzikiego szczepu muszki owocowej. Badania prowadzono przez dziesięć pokoleń Drosophila. Benzoesan sodu jest powszechnie używanym konserwantem dodawanym m.in. do sosów, keczupów i napojów. Cytrynian jednosodowy jest stosowany jako regulator kwasowości, stabilizator oraz przeciwutleniacz. Najczęściej dodaje się go do dżemów, marmolad, galaretek, serów topionych, kiełbas i konserw mięsnych. Podczas przedstawionych badań zastosowano dwa stężenia powyższych dodatków do żywności: 0,8 mg o kg-' i 1,6 mg o kg- 1 benzoesanu sodu (E211) oraz 2,0 go kg-' i 4,0 go kg-' cytrynianu jednosodowego (E331). Z analizy otrzymanych danych wynika, iż przy dawkach minimalnych zalecanych (0,8 mg - kg-' E211 i 2,0 go kg-' E331) w żywności substancje te nie wpływały znacząco na plenność samic, masę ciała i strukturę płci Drosophila melnogaster.

Obesity is a foremost but preventable cause of deaths globally. It is a significant risk factor for the development of cardiovascular diseases, particularly heart failure, and diabetes. Natural products such as some foods, fruits, medicinal plants have been known to be functional in the management of Obesity. This article is aimed at reviewing the weight loss and anti-obesity potentials of Ginger (Zingiber officinale), Avocado (Persea americana) and Green Tea (Epigallocatechin gallate, EGCG). Google Scholar, PubMed, NCBI and Elsevier databases were searched from 2004 to 2020 using specific keywords. Searching was restricted to English language. Seventeen articles (Eleven human studies and six animal studies) were included in this review. Majority of the research papers that were considered in this review supported the weight loss and anti-obesity potentials of these natural products in obese human and animal subjects by lowering most of the clinical markers of obesity. Some of the anti-obesity mechanisms proposed by the authors include suppression of lipogenesis, inhibition of ghrelin secretion, e.t.c. This article also established the need for future trials.

There is a large number of chemicals known to act as food preservatives. But there are only few of them in use which in law doses have antibiotic activity, do not influence physical properties or food taste, and they are save for the consumer. Acids constitute a large group among chemicals approved as food preservatives. It is evident that the effect of food preservatives depends on their applied concentration. However, the dose of food preservative should be in limits that are approved for the consumer's safety. The aim of the presented studies was the estimation of influence of lactic acid (LA), widely used in food preservation, on the body weight, fertility and sex ratio of the fruit fly (Drosophila melanogasler). In the experiments, a wild tribe of the fruit fly was used. The fly was grown over ten generations on standard feeding medium lo which lactic acid was added at the concentration of 1.5, 2.0 or 2.5 %. A control population was grown on medium without lactic acid. The experi-ments were carried out in three independent repetitions. The results were elaborated statistically by the use of Duncan test. A statistical verification of deviation of the predicted sex ratio (1:1), including all generations of control and experimental groups, was made using X2 test. The obtained results have shown that added doses of LA did not affect females' fertility, body weight or sex ratio of the fruit fly (Drosophila melanogasler). It could be stated that LA is a very profitable additive, due lo its antimicrobial properties and improving quality of food for fruit fly.

Znanych jest wiele związków chemicznych o działaniu abiotycznym, do konserwowania żywności. Jednak używane są tylko nieliczne substancje, które w dopuszczalnych dawkach w sposób ogólny lub wybiórczy uniemożliwiają rozwój drobnoustro-jów, nie wywołując zmian organoleptycznych i fizycznych żywności i nie oddziałując szkodliwie na człowieka. Wśród sub-stancji dozwolonych do konserwowania żywności znaczną liczbę stanowią kwasy. Wydaje się oczywiste, że oddziaływanie środka konserwującego ujawni się tym szybciej i wyraźniej, im większa jest jego dawka. Dawka substancji konserwującej, którą człowiek pobiera z pożywieniem, powinna mieścić się w wyznaczonych normach i nie działać szkodliwie. Celem przeprowadzonych badań była ocena wpływu szeroko stosowanego w żywności kwasu mlekowego na masę ciała, plenność i strukturę płci muszki owocowej Drosophila melanogaster. W doświadczeniu użyto muszek szczepu dzikiego (Dz), które hodowano przez 10 pokoleń na pożywce standardowej (kontrola) oraz z dodatkiem trzech stężeń kwasu mlekowego (E270: 1.5, 2.0; 2.5 %). Wszystkie hodowle były w trzech powtórzeniach. Uzyskane wyniki opracowano za pomocą analizy wariancji oraz testu Duncana. Statystyczną weryfikację odchyleń od przewidywanego stosunku płci 1:1, łącznie dla wszystkich pokoleń grupy kontrolnej, jak i grup doświadczalnych, przeprowadzono za pomocą testu X2. Analiza otrzymanych da-nych wykazała, iż zastosowane dawki kwasu mlekowego nie wpływały statystycznie istotnie na plenność samic, masę ciała i strukturę płci Drosophila melanogaster. Można stwierdzić, że kwas mlekowy jest korzystnym dodatkiem do pożywki muszki owocowej, gdyż nie zakłóca jej podstawowych procesów życiowych.

Background. Weight-reducing diet is often used by the athletes, for example, to fit a proper body weight category. Usually it is done inappropriately, which can affect the athlete’s performance and health. The purpose of the study is to collect information on a diet of Polish rowers. Material and methods. The survey was conducted from December 2016 to September 2017. We asked competitors of 6 sports clubs. The data were collected using an online survey to evaluate food frequency and rowers’ nutrition knowledge. Also, the verified effectiveness of weight loss measures was taken. Results. Of the 17 respondents, only one person had never used a weight-reducing diet. Typically, the period of reduced energy supply was 1 to 4 weeks. Most athletes (59%) after competition returned to their output weight and 35% of the athletes exceeded. Only 26% of the respondents consulted a dietitian. In 88% of athletes, sport results improved or did not change during the hypocaloric diet. Consumption of individual products varied depending on the type of diet used. All rowers used supplementation. Conclusions. The vast majority of athletes have been on a weight loss diet. Frequent consumption of different foods varies depending on the preparation of the food. There is a need to conduct research with a standardized frequency of intake and to appear more credible.

Wstęp. Problem utrzymania optymalnej dla konkretnej kategorii wagowej masy ciała stanowi wyzwanie dla zawodników. Dlatego często podejmują się oni nieprzemyślanej redukcji masy ciała negatywnie wpływającej na wyniki sportowe i kondycję zdrowotną. Celem badania było uzyskanie informacji na temat podejścia polskich wioślarzy do procesu redukcji masy ciała oraz metod jej przeprowadzania. Materiał i metody. Badanie prowadzono w okresie od grudnia 2016 do września 2017 roku wśród zawodników 6 polskich klubów. Dane zebrano z wykorzystaniem autorskiego kwestionariusza, uwzględniającego pytania oceniające częstość spożycia produktów z poszczególnych grup produktów spożywczych w okresie redukcji masy ciała i poza nią oraz oceniające wiedzę wioślarzy w zakresie żywienia. Ponadto, zweryfikowano skuteczność podejmowanych działań redukcji masy ciała. Wyniki. Aż 16 spośród 17 ankietowanych osób stosowało dietę redukcyjną. Jej czas trwania wynosił zwykle od 1 do 4 tygodni, ale jedynie 26% badanych skonsultowało ją z dietetykiem. 59% sportowców po sezonie startowym wróciło do swojej początkowej masy ciała a aż 35% osób przytyło powyżej tej wartości. U 88% zawodników wyniki sportowe uległy poprawie lub nie zmieniły się w czasie stosowania diety redukcyjnej. Spożycie poszczególnych produktów różniło się w zależności od okresu stosowania diety. Wszyscy zawodnicy wspomagali dietę suplementacją. Wnioski. Zdecydowana większość zawodników stosuje dietę redukcyjną w celu uzyskania odpowiedniej dla kategorii wagowej masy ciała, jednak ich podejście do diety i rozumienie zasad żywieniowych jest zróżnicowane Dlatego istnieje potrzeba edukacji zawodników jak i ich trenerów w zakresie racjonalnych metod uzyskania i utrzymania masy ciała.

The length and body weight at subsequent annuli of four facultative riverine fish species: roach (Rutilus rutilus L.), perch (Perca fluviatilis L.), bream (Abramis brama L.) and pike (Esox lucius L.) living in lakes and rivers were compared on the basis of published data. Pike grew better in lakes (significant differences in length, and some for weight), but the other species in rivers. However, significant differences between medians were observed in all cases only for body length of roach, in many cases for the length of bream, as well as a few for its weight, and no one for perch. Comparable data on relative fecundity in both habitats were available for roach and pike. Pike females produced more eggs in lakes, but roach - in rivers, and the differences were significant.
