Vliv životního stylu středoškoláků na vybrané parametry tělesného složení / Influence of life style on selected parameters of the body compositionMurko, Igor January 2017 (has links)
Title: The influence of lifestyle on selected parameters of body composition of high school students. Objectives: The main objective of the thesis is to determine the impact of lifestyle on selected components of body composition of the high school students. The secondary objective is the statistical processing of data obtained from the body composition measurements and from the responses obtained from the questionnaires about lifestyle. Method used: 60 high school students aged 17-20 years were measured by BIA method. Appliance used for the measurement was BODYSTAT 1500. We obtained information about lifestyle from questionnaires. Results: The average percentage of body fat of boys is 12.2 ± 2.6 %. In comparison with the standard, these boys have lower or below average values. The average value of body fat of girls is 22.5 ± 5%. We consider this average value as normal. 43 % of the respondents sleep 7-8 hours per day as recommended. Boys drink more water than girls. The average time spent with a cell phone and with a PC by respondents per day is 3.2 h ± 1.5 hours. The most common answers of way of spending free time are sports, activities with friends and family, watching movies/TV shows and reading books. Most students (65 %) use public transportation to get to school. 48 % of students perform...

Women of childbearing age: dietary patterns and vitamin B12 statusXin, Liping January 2008 (has links)
From conception the dynamic balance between nutritional and activity factors play a role in the accumulation of risk for future disease. Maternal nutrient balance and the subsequent dietary pattern of the family set the path for the growth and development of the individual and therefore also for their offspring. There is strong evidence from studies in India that mothers who have a low vitamin B12 status, but high folate, will have children with higher adiposity and more cardiovascular risk factors than those with adequate B12. The B12 status is closely linked to the dietary pattern particularly the consumption of red meat which has a high B12 content. In New Zealand there are an increasing number of Indian migrants. Vegetarianism is also practiced by an increasing number including young women. In addition, there is a high rate (up to 60%) of unplanned pregnancies in New Zealand. In the 1997 New Zealand National Nutrition Survey (NNS97) report, vitamin B12 intake appeared adequate for the New Zealand population and breakfast cereals were reported as one major dietary source of B12. Cereals in New Zealand however, were not fortified with B12 and there was an error in the FOODfile™ data entries for B12 in some cereals. The raw data of reported B12 intakes in the 24-hour diet recall (24HDR) of NNS97 was reanalysed at the individual level by subtracting the B12 derived from breakfast cereals and applying the 2005 revised estimated average requirement (EAR) value. The possible prevalence of B12 insufficiency was 2.4 times that originally reported by the NNS97, translating into a prevalence of up to 27% of the population sampled. This analysis was limited as it was not adjusted for day-to-day variance or to the New Zealand population. This apparently high prevalence of risk for inadequate B12 intake in the surveyed individuals required confirmation that the B12 intake from 24HDR and also a 7-day diet diary (7DDD) was a valid assessment of B12 status. The group of particular interest is women of childbearing age (18-50y) with a range of eating patterns. Thirty eight women aged 19-48y; 12 non-red-meat-eaters (5 Indians vs. 7 non-Indians) and 26 red-meat-eaters (1 Indian vs. 25 non-Indians) participated in this validation study. Anthropometry and hand-to-foot bioelectrical impedance (BIA) were measured on the same day as a 24HDR was recorded. Fasting serum lipids, glucose, haematological parameters, and serum B12, holotranscobalamin II (holo-TC II, a specific B12 biomarker), and folate concentrations were measured. Foods eaten and time spent in physical activity during the following 7 days were extracted from 7DDD and 7-day physical activity diary (7DPAD). There was no significant correlation between dietary intake (24HDR or 7DDD) and biomarkers for B12 status. Indians reported lower mean daily B12 intakes in 7DDD than non-Indians (1.6 vs. 4.5 μg/day, p<0.001) and this was confirmed by Indians’ significantly low serum B12 (203 vs. 383 pmol/L, p=0.04) and holo-TC II (35 vs. 72 pmol/L, p=0.02) concentrations compared to non-Indians. A similar pattern was found between non-red-meat-eaters and red-meat-eaters in daily B12 intake in 7DDD (2.3 vs. 4.8 μg/day, p<0.001) and in B12 biomarkers (serum B12, 263 vs. 397 pmol/L, p=0.01; holo-TC II, 43 vs. 77 pmol/L, p<0.005). Non-red-meat-eaters reported significantly higher daily folate intake in 7DDD (359 vs. 260 μg/day, p=0.01) than red-meat-eaters but no significant difference was found in serum folate concentration between these groups (29 vs. 24 pmol/L, p=0.10). Indians/non-red-meat-eaters also reported lower daily protein intake and higher percentage of total energy from carbohydrate in 7DDD compared to non-Indians/red-meat-eaters but total reported energy intake tended to be under-reported and physical activity over-reported when assessed against estimated basal metabolic rate (BMR). Body composition varied by dietary pattern. Indians/non-red-meat-eaters had higher body fat percentage (BF %) and weaker grip strength than non-Indians/red-meat-eaters. In addition, Indians had a significantly higher waist-to-hip ratio (WHR) than non-Indians. Overall, the whole group reported that they were inactive. The median time spent in moderate, high and maximal intensity activities was only 19 minutes a day, which did not meet the NZ guideline for adults of 30 minutes a day. In this small study nutrient analysis of diet by 24HDR or 7DDD, was not a reliable or accurate way to assess B12 insufficiency. Questions about dietary patterns such as “do you eat red meat”, and taking ethnicity into account could more easily identify the at risk population. Supplementation and/or fortification of B12 should be considered before pregnancy.

Accuracy In Body Composition Assessment With Three Different Methods Compared To DexaDuz, Serkan 01 January 2003 (has links) (PDF)
The purpose of this study was to investigate differences among the percent
body fat (%BF) values of Turkish sedentary male and female university students
measured by dual-energy x-ray absorptiometry (DEXA), skinfold (SKF), ultrasound
(US) and hand to hand bioelectrical impedance analysis (BIA). Two hundred eight
Turkish university students (one hundred four males and one hundred four females)
aged between 18 to 26 years old participants participated in this study voluntarily.
%BF assessment was performed by the SKF, US, BIA and DEXA methods.
Differences among DEXA, SKF, US and BIA were examined by applying a series of
paired-t test. Multiple regression analyses were conducted to developed regression
equations to predict %BF from SKF and US measurements. Results demonstrated
that there were significant differences between DEXA and SKF, US, and BIA
measurements for males and females. The mean %BF derived from DEXA was
significantly (p< / .001) greater than those of SKF, US and BIA for males and females.
Multiple regression analyses showed that SKF and US measurement of subcutaneous
fat at three-sites gave the best prediction to %BF for male and female separately. The
multiple correlations using three sites simultaneously for men and women were
r=0.92, SEE=2.4 and r=0.91, SEE=2.8 for SKF and r=0.93, SEE=2.3 and r=0.90,
SEE=3.0 for US, respectively. In summary, with the new regression equation US
appears to be a reliable, portable, and non-invasive tool which can be used by any
field investigator on obese or thin individuals. Finally, new regression equations
developed do not seem to be superior to those reported using calipers.

aculeata pulp by-product (maca?ba) on nutritive value, fermentative characteristics, losses of
fermentation and influence on aerobic stability of Elephant grass silages (Pennisetum
Purpureum Schum.). The experimental design was completely randomized with 4 replicates.
The treatments were constituted by Elephant grass forage with six leves of maca?ba coconut
pulp cake (MCPC) based on natural matter (0, 6, 12, 18, 24, 30%). The silos were storage by
150 days in experimental polyethylene (PVC) silos. The nutritive value, fementative
characteristics, losses and aerobic stability were determined. There was an increasing linear
effect (P <0.05) of MCPC doses on the mean dry matter (DM), ether extract (EE), non-fibrous
carbohydrates (NFC) and in vitro dry matter digestibility (IVDMD) of Elephant grass silages.
However, neutral detergent fiber (NDF), neutral detergent fiber corrected for ash and protein
(FDNcp) , acid detergent fiber (ADF), and crude protein (CP) were linearly reduced (P <0.05)
as the addition of MCPC was increased. The inclusion of MCPC linearly increased (P <0.05)
the pH values and reduced the ammoniacal nitrogen (N-NH3) values of the silages. The
values of effluent production in the silage decreased linearly (P <0.05) with inclusion of the
additive. The gas loss values presented a quadratic response (P <0.05) as the addition of
MCPC to the silages increased. Aerobic stability was affected in Elephant grass silages,
showing an increase in stability as the inclusion dose of MCPC was increased. In general, the
addition of MCPC improves the nutritive value and fermentative parameters of Elephant grass
silage. Recommended the inclusion of 15% of this additive.

Olycks- och tillbudsrapportering med BIA inom byggindustrinRittmalm Glimne, Linn, Oredsson, Viktor January 2018 (has links)
Trots en positiv utveckling de senaste åren inom den svenska byggbranschen med minskat antal allvarliga olyckor, förekommer allvarliga olyckor och till och med dödsfall fortfarande. Forskning visar att rapportering av olyckor och tillbud kan vara en bidragande orsak till att förebygga och minska förekomsten av dessa. Sedan 2011 finns ett gratis rapporteringssystem för kollektivanslutna bygg- och anläggningsföretag som heter BIA, och som används av bland annat Skanska. Studiens syfte är att ta reda på hur rapporteringssystemet används idag samt om och hur det skulle kunna användas på ett bättre och effektivare sätt. Den utforskande forskningsmetoden som används i denna studie är främst fallstudie, där tre byggarbetsplatser besökts och där BAS-U, skyddsombud och yrkesarbetare på respektive plats intervjuats för att undersöka attityder till arbetsmiljö samt kunskapsläget och användningen av BIA. Deltagande observationer på den största av arbetsplatserna har kompletterat intervjuerna tillsammans med litteraturstudie där fokus legat på arbetsmiljölagstiftningen, Skanskas arbetsmiljöarbete, BIA-systemet och rapporteringskultur. Överlag visar resultatet på att användarna av BIA är nöjda med verktyget, med några undantag, men också att kunskapen om hur man ska använda BIA och alla dess funktioner inte är så hög som de som använder programmet själva önskar. Detta ihop med BIA:s upplevda begränsade användarvänlighet visar att det finns en underutnyttjad potential som skulle kunna gynna det dagliga arbetsmiljöarbetet mer. Efter att ha genomfört denna studie bedömer vi att BIA skulle kunna användas effektivare om användarna, framför allt BAS-U, fick någon typ av utbildning i programmet. Som kunskapskälla skulle BIA kunna användas som redskap i vardagligt förebyggande säkerhetsarbete, exempelvis vid riskinventering för arbetsberedningar. Eftersom rapporteringssystemet är gratis för kollektivanslutna företag och bara kräver en vanlig webbläsare är verktyget relativt lättillgängligt, och skulle kunna användas av byggbranschen i betydligt högre grad än det görs idag. Fler användare och fler rapporter hade bidragit till större kunskapsunderlag, och sannolikt även snabbare utveckling av BIA. I denna studie presenteras också konkreta förslag på hur användningen redan idag kan ökas och effektiviseras. / The last few years have seen a positive development regarding the number of incidents and accidents in the Swedish construction industry, but serious accidents and even deaths still feature in the statistics. Research shows that reporting accidents, incidents and other safety-related occurrences may lead to a decrease in the number of them. As of 2011, a simple, web-based and free-of-use reporting system available to any construction company employing union members exists: called BIA, it’s used by Skanska, among other companies. This study set out to explore how BIA is being used today, and if and how it could be used more effectively.The study concludes that BIA’s use could easily be improved in a way that contributes significantly to daily safety work, for instance by providing the most frequent users – BAS-U – with knowledge about BIA’s features, such as the analysis tool, that could be used when creating new worksets. If the construction industry were to use BIA to a higher degree, a greater data set would also be created, further increasing the possibility of learning from the reports in the system. A few simple suggestions for increasing and improving use are provided at the end of this study.

A critical evaluation of the quality of biodiversity inputs to environmental impact assessments in areas with high biodiversity value : experience from the Cape Floristic Region / Trevor Winston HallatHallatt, Trevor Winston January 2014 (has links)
Biodiversity considerations form an essential component of Environmental Impact
Assessment (EIA), especially in areas with both a high biodiversity value and development
pressure such as the Cape Floristic Region (CFR) in South Africa. Limited research has
been conducted within the South African context on the quality of biodiversity inputs to EIA.
The aim of this research was to evaluate the quality of biodiversity input to EIA in the CFR.
To address this aim, a customised review package was generated to evaluate the quality of
26 Biodiversity Impact Assessment (BIA) reports in the CFR. The results were then
compared with international trends of biodiversity input to EIA in order to show how prevalent
such trends are within an area with high biodiversity value. This comparison showed that the
quality of biodiversity input to EIA in the CFR generally concur with inadequacies identified in
international EIA literature. Typically, significant weaknesses identified during the review
were the lack of public participation and an insufficient evaluation of alternatives. Specialists
also failed to develop adequate monitoring programmes. Furthermore, a very pertinent
limitation was that, in general, assessments are conducted during inappropriate seasons and
over insufficient time periods. However, some variations to the international trends are also
present within the Region. For example, a particular strength was that a precautionary
approach was adopted by most of the specialists to avoid negative impacts on biodiversity.
In addition, specialists did not merely focus on lower levels (species and habitats) of
biodiversity, but incorporated ecological processes in assessment techniques. The
inadequacies identified in this dissertation pose particular challenges for biodiversity
management and conservation practices. The development and implementation of
mechanisms such as Best Practice Guidelines and improved biodiversity related legislation is
proposed to improve biodiversity input to EIA. / M Environmental Management, North-West University, Potchefstroom Campus, 2014

Efeitos de um programa de treinamento contra resistência sobre a composição corporal, a força muscular e a flexibilidade de mulheres idosas / Effects of resistance training program on body composition, muscle strength and flexibility of elderly womenBarbosa, Aline Rodrigues 15 February 2000 (has links)
Esse estudo analisou os efeitos de 10 semanas de treinamento contra resistência, sobre a composição corporal, a força muscular e a flexibilidade de 11 mulheres idosas (68,91 ± 5,43 anos). Um grupo de 8 idosas (65,13 ±4,09 anos) serviu como controle inativo. A força de preensão manual (ambas as mãos), o percentual de gordura corporal (dobras cutâneas e bioimpedância) e a flexibilidade (teste \"sentar e alcançar\") foram avaliados antes e após 10 semanas. A força muscular isotônica foi avaliada pelas cargas de treinamento. Após as avaliações iniciais, os indivíduos começaram o programa de treinamento que consistiu de oito exercícios (peito, costas, ombro, bíceps, tríceps, coxa, panturrilha e abdome), sem a realização de exercício para flexibilidade. O programa de treinamento resultou em aumentos significativos (p< 0,001) na força muscular isotônica, para todos os exercícios, com aumentos percentuais que variaram de 25,91% a 49,09%, para tríceps e panturrilha, respectivamente. Verificaram se aumentos significativos (p < 0,001) na força de preensão manual de ambas as mãos e também na flexibilidade no grupo submetido a treinamento. O programa de treinamento não resultou em alteração na gordura corporal avaliada por bioímpedância e equação de dobras cutâneas, contudo verificou-se redução no Σ 8DC (p≤0,01). Não foram observadas alterações no grupo controle, em nenhuma variável investigada. Conclui-se que o programa de treinamento utilizado foi eficaz para aumentar a força muscular e a flexibilidade das mulheres idosas, reduzir o Σ 8DC, contudo não provocou redução do percentual de gordura corporal. / This study analyzed the effects of a 10-wk resistance training program on body composition, muscle strength and flexibility in 11 elderly women (68.91 ± 5.43 yr.). A control group of 8 women (65.13 ± 4.09 yr.) served as inactive controls. Hand grip strength (both hands), body fat percent (skinfold thickness and bioelectrical impedance) and flexibility ( \"sit and reach\" test) were assessed before and after 10 weeks . The isotonic muscle strength were assessed by the weight of training . After initial tests, the subjects began a training program consisting of eight exercises for all body (chest, back, shoulder, biceps, triceps, thigh, calf and abdomen), without flexibility exercises. The training program resulted in significant increase (p< 0.001) in isotonic muscle strength, for all exercises, with increases ranged from 25.91% to 49.09%, for triceps and calf, respectively. It was observed significant increase (p<0,001) in hand grip strength (both hands) and flexibility in the training group. The training program resulted in no decrease in body fat assessed by bioelectrical impedance and skinfold thickness equation, but we observed decrease in Σ 8ST (p≤ 0.01). No significant changes were observed in the control group by ariy variable. In conclusion, the training program utilized was effective in increase muscle strength, flexibility and reduced Σ 8ST. However, the training program did not reduce body fat percentage.

The training program resulted in no decrease in body fat assessed by bioelectrical impedance and skinfold thickness equation, but we observed decrease in Σ 8ST (p≤ 0.01). No significant changes were observed in the control group by ariy variable. In conclusion, the training program utilized was effective in increase muscle strength, flexibility and reduced Σ 8ST. However, the training program did not reduce body fat percentage.
