Introduction. During assessing physical activity researchers often use self-reported methods which may not meet psychometric standards and can lead to false results due to the application of inaccurate or wrongly chosen tools. Aim of Study. The aim of this paper was to compile a list of most popular questionnaires used for assessing physical activity among the elderly and to examine their qualitative and psychometric characteristics. Methods. An analysis of articles published in international scientific journals on the topic of physical activity assessment among elderly people was performed in order to select reliable and valid questionnaires. Results. Twenty-one papers containing information on psychometric criteria of eleven questionnaires were analyzed. The majority of reliability and validity studies were performed on the PASE and YPAS questionnaires. In terms of objectivity, the best ones turned out to be the CHAMPS, IPAQ, PAQE, PASE, and YPAS questionnaires. The highest reliability assessment scores were given to the APAFOP, PAR, PAQE, and QAPSE questionnaires. The best validation scores with objective methods assessing physical activity were carried out for the APAFOP, PAQE, PASE, and YPAS questionnaires. Conclusions. Among the analyzed questionnaires, the best one in terms of objectivity, standardization, validity, and reliability was the Yale Physical Activity Survey (YPAS).
The objective of the reported study was a trial of selecting factors that differentiate and, simultaneously, determine a sports level of women specializing in race walking. The study covered 35 one-year training macrocycles. The material collected was divided into three blocks. The study was conducted with the method of recording, gathering and analysis of training loads worked out at the Department of the Theory of Sports, Academy of Physical Education in Warsaw. Use was also made of the classification of training means groups for the event of race walking elaborated by Krzysztof Perkowski, with own modification. Differences in training loads between three groups of sportswomen were evaluated with the use of a one-way analysis of variance (a parametric test ANOVA), and the Kruskal-Wallis test (a non-parametric test). Once the result was significant (p<0.05), the differences between groups were evaluated with the Tukey (RIR) test (for parametric tests) or with the multiple comparison test (for the Kruskal-Wallis test). Loads that significantly differentiated the training of sportswomen at various levels of advancement turned out to be efforts realized in the fourth area of energetic transformations (T₄), directed loads (D) as well as versatile loads realized in the fourth area of intensity (V₄). The achievement of high scores is facilitated by reduction of those loads and by increasing the special loads realized in the fourth area of energetic transformations (S₃), the effect of which appeared to be statistically significant. Another factor differentiating the levels of sports advancement turned out be the special loads realized in the fifth area of intensity (S₅).
Two groups of turkeys: slow-growing primitive turkeys (SS n = 80 and n = 80) and fast-growing Big-6 turkeys (<$<$ n = 80 and n = 80) were reared in a semi-intensive system: turkey hens until 14th week whereas turkey toms until 22nd week of life. Twelve males and twelve females with body weight corresponding to the mean body weight in a group were selected from each group for slaughter and slaughter performance analysis. A significantly (P < 0.01) higher body weight and weight of all anatomical parts examined were found in both hens and males of Big-6 turkeys. An exception was the weight of abdominal fat (P < 0.05) and weight of gizzard (NS) in males. In turn, Big--6 females were characterized by a significantly (P < 0.01) higher percentage of: breast muscles (by 8.7), leg muscles (by 2.4) and abdominal fat (by 0.9), and significantly (P < 0.01) lower percentage of: wings, heart, liver and gizzard (by respectively: 0.2, 0.1, 0.3 and 1.9) in the body weight. In the case of Big-6 males, analyses demonstrated a significantly (P < 0.01) higher percentage of breast muscles (by 16.5) and leg muscles (by 2.5, P < 0.05), and lower (P < 0.01) percentage of wing, heart, liver and gizzard (by respectively: 0.3, 0.2, 0.7 and 1.5) in the body weight, compared to the primitive turkeys.
The aim of this study was to examine relationships between results of soccer-specific skill tests and game-related soccer skills in young players aged 12 and 15 years. The participants were 60 male soccer players aged 11.87-14.76 years divided into two groups: lower secondary school candidates (12y) aged 11.87 ± 0.23 years (n = 30), and upper secondary school candidates (15y) aged 14.76 ± 0.42 years (n = 30). Soccer-specific skills were assessed using two outdoor tests in competitive match conditions: Dribble Test and Turning Test. The assessment of the game-related skills was carried out by five expert judges during a 5 vs 5 small-sided game. The evaluation criteria had been set by a panel of experts. The reliability of game-related skills assessments procedures was calculated using intra class correlation (ICC), standard error of the mean (SEM), coefficient of variation (CV). Spearman’s rank correlation coefficients were used to determine the relationships between results of assessments of game-related skill and soccer-specific skill tests. Relationships between soccer-specific skills and game-related skills in 15-year-old players (–0.325 to –0.452) are less pronounced than in 12-year-old players (–0.496 to –0.667). It seems to be unjustified to use soccer-specific skill tests for prediction of young soccer players’ potential. The results of these tests can depend on numerous biological differences in the development of adolescent players. In conclusion, evaluation of players by judges should be part in talent identification models in youth soccer.
Fish and other fishery products are subjected to the official sanitary-veterinary controls as required by Regulation (EC) No 854/2004. The aim of the study was to analyse the results of sanitary-veterinary examinations of fish in Poland in 2010-2016 conducted by the Veterinary Inspection. The results of the laboratory examination on fish were worked out based on the annual reports issued by the General Veterinary Inspectorate. The analysis of the results included the sanitary-veterinary examination of marine and farmed fish (salmonids, cyprinids and other fish species) carried out by the Veterinary Inspection. Moreover, the sanitary evaluation of samples of fish, seafood and their products on the basis of microbiological, chemical and sensory analysis results performed by the State Sanitary Inspection (PIS) were used. Throughout the analyzed period, a total of 1 436 109 009.60 kg of fish were examined, in that 145 711.71 kg (0.01%) were declared unfit for human consumption. The most important reasons for fish rejection proved to be parasite invasions (45.91% of the total amount of discarded fish), viral diseases (41.74%), bacterial diseases (9.71%) and the exceeded acceptable level of histamine (2.56%) and dioxins (0.07%). The sanitary examination of the food samples carried out by the PIS showed that the causes of rejection included the surpassed levels of food additives (2.3-2.7% of all the discarded samples) and chemical contaminants (1.4-2.4%) as well as abnormal microbiological and sensory tests results (0.1-1.2%). Summing up, the amount of fish rejected during the analyzed period was low which indicates the good quality of the obtained raw material.
Analysis of results assessment of growth of Charolais beef cattle in Poland. The aim of the study was to assess the utility of selected results of the French Charolais breed with respect to their compliance with the goal of racial breeding and standards adopted by the Polish Association of Breeders and Producers of Beef Cattle (PABPBC). The subject of the analysis were recording results of the French Charolais beef cattle breed in Poland. The study was based on data for the years 2002-2013 of PABPBC and the National Center of Animal Breeding (NCAB) for 1996-2001. The data set included: n - the number of animals tested, min. - Minimum values in the studied traits, max. - the maximum value of the selected features, average - average values of the analyzed traits, SD - standard deviation. Evaluated properties are: average weight of cows (kg), the average body weight of calves after birth (kg), the average daily gains for age 210 days (g), the average body weight of calves at the age of 210 days (kg), the average milk yield (kg), the terms of cows and heifers calving aptitude, the distribution of the population according to the order of calving cows. One can observe a gradual decline in the share of Charolais breed in national beef cattle population, also shows a significant decrease in the number of crossbreds with Charolais breed. The average weight of cows in 2005-2006 amounting to 559.4 and 570.2 kg meet the standards for breeding of cows entered in the initial part of the herd book, which define the minimum weight of Charolais cows after first calving as 550 kg. The average weight at birth of heifer calves in each year assessment was similar, but after 2008 began more than 40 kg. In purebred bull calves was seen a systematic increase in the average birth weight. The difference in birth weights between heifers and bulls ranged from 1 kg in 1999 to 3.6 kg in 2012. High average daily weight gains of bulls to 210 days of age, at short extra supplementary fattening period of about one month allow to export the animals weighing about 300 kg at an good price. The average daily gains of heifers (550-560 g), guarantee obtaining at 15 months of age body weight allowing the commencement of breeding. From 30.4 to 47.8% Charolais cows in recent years delivered in the relevant period.
One of the main problems of agriculture in the CEEC, namely the level of employment in agricultural sector at the moment of their accession to the EU was presented in the report. The paper characterizes also the changes that have already happened and will have to happen in future. The level of employment in agriculture, share of agriculture in employment and the number of employed on 100 ha of UAA in CEEC and EU-15 were compared.
A post-marketing surveillance study (PMSS) was carried out in Poland with 313 childrei aged 3-10, predisposed to upper respiratory tract infections. The study participant received Bioaron C® syrup, containing aqueous extract of Aloë arborescens leaves, juice o Aronia melanocarpa fruit and ascorbic acid. The main object of the present study was ti investigate its tolerability and influence on the course of an acute URTI in children. Amon; the study participants 14% received Bioaron C® as a single medication and 86% of thi patients received concomitant medications. The efficacy of the treatment was measurei according to a validated symptom score. The best results were obtained for symptom related to rhinitis and bronchitis but there was no major effect seen on pain and fevei Within the subscores rhinitis and bronchitis Bioaron C alone was able to lead to ai improvement and could contribute to a reduction in particular of the single symptom blocked and runny nose, cough and hoarseness. Treatment with Bioaron C resulted in a sig nificant improvement of the symptomology of URTI. Bioaron C was tolerated very well.
W hodowli rzepaku ozimego i innych roślin istotnym zagadnieniem jest poznanie zmienności i współzależności podstawowych cech fenotypowych, zwłaszcza użytkowych, umożliwiających wyznaczenie kryteriów selekcji genotypów o wysokiej potencjalnej plenności, wynikającej między innymi z odpowiedniej relacji tych cech. W niniejszej pracy przedstawiono kilka graficznych metod prezentowania wyników doświadczeń. Materiał do badań stanowiły cztery mieszańce zrestorowane F1 CMS ogura: PN 4534/01, PN 4556/01, PN 4538/01, PN 4540/01 oraz cztery mieszańce złożone F1 CMS ogura rzepaku ozimego: Kaszub F1, Lubusz F1, Mazur F1 i Pomorzanin F1. Obiekty te badano w dwóch miejsco-wościach (Borowo i Zielęcin) w dwóch sezonach wegetacyjnych (2002/2003 i 2003/2004). W celu graficznej prezentacji zależności wybrano cztery cechy: plon nasion, liczbę nasion w łuszczynie, masę tysiąca nasion oraz zawartość tłuszczu. Charakterystyka pozycyjna badanych obiektów dla poszczególnych cech została przedstawiona na wykresach pudełkowych (boxplot). Współzależności pomiędzy cechami przedstawiono na wykresach rozrzutu, natomiast zależności pomiędzy obiektami na wykresie typu „sieć rybacka” (ang. parallel coordinate plot). Wizualizacja wyników eksperymentalnych jest dobrą metodą pozwalającą na przedstawienie zależności pomiędzy cechami i obiektami, którą można stosować jako alternatywną do metod tradycyjnych lub jako ich uzupełnienie.
