Despite many studies describing the physiological characteristics of professional road cyclists and recent work describing the demands of competition, there is a paucity of similar information regarding elite mountain bike (MTB) cyclists. The aim of the present work was to describe the physiological characteristics and the demands of competition for successful MTB cyclists relative to successful road cyclists. Internationally competitive cyclists from both disciplines (seven MTB and seven road) completed the following laboratory tests: anthropometric measurements, an incremental cycle ergometer test and a 30 minute laboratory time trial. In addition, the power output profile obtained in the field from a world-class MTB cyclist riding a simulated race were compared to successful road cycling performances (placing top 3) in flat (FLAT), semi-mountainous (SEMO), high-mountainous (HIMO), individual time trial (ITT) and criterium (CRIT) road races. Due to conversion problems, 6 sentences have been omitted. For full abstract, see 01front.pdf. These results indicate that success in international MTB racing requires high power-to-weight characteristics complemented by a light and lean physique. MTB racing is associated with greater torque at the pedal crank, a more constant effort with less time at lower power outputs and a higher frequency of highintensity surges than road racing. Therefore coaches should take into account these unique MTB racing characteristics when devising training programs for elite athletes.

Thyroid dysfunction is one of the most common endocrine disorders in women of childbearing age and the obstetric consequences of abnormal thyroid hormone levels during pregnancy have been established. Less understood is the implication of the presence of maternal thyroid autoantibodies on infant outcomes among women who are euthyroid during pregnancy. The objective of this study was two-fold: 1) to examine the influence of antenatal thyroperioxidase (TPO) status on fetal/infant brain and body growth measurements at delivery and 2) to explore the relationship of antenatal TPO status and maternal postpartum thyroid dysfunction (PPTD) on early infant growth and neurocognitive development. Six-hundred thirty-one (631) euthyroid pregnant women were recruited from prenatal clinics in Tampa Bay, Florida and the surrounding area between November 2007 and December 2010. TPO status was determined during pregnancy and fetal/infant brain and body growth variables were assessed at delivery. A subsample of forty-one (41) mother-infant dyads participated in a 6-month longitudinal supplemental study. Infant growth assessments were conducted at 3, 4, 5 and 6 months postpartum. Regression analysis revealed maternal TPO positivity was significantly associated with smaller head circumference, reduced brain weight and lower brain-body-ratio; however maternal race/ethnicity was identified as an effect modifier in the relationship. No significant differences were noted in birth weight, birth length, abdominal circumference or chest circumference measurements among infants born to TPO positive mothers of any racial/ethnic group as compared to their negative counterparts. Mixed model analysis of the smaller subset (n=41) revealed infants of TPO+ mothers were smaller at birth but experienced accelerated growth between birth to 3 months when compared to infants born to TPO- mothers. This acceleration led to their catch-up in growth to their TPO negative counterparts by 3 months of age. No significant differences were noted in neurocognitive outcomes between infants born to TPO+ mothers compared to those born to TPO- mothers. The findings in this dissertation indicate that maternal/race ethnicity modifies the relationship between TPO positivity and reduced fetal/infant brain growth. Additionally, the analyses suggest that maternal autoantibody status could lead to variations in early infant growth and development. The end-result of these variations is unclear. Further research is needed to determine the potential impact of reduced head circumference and accelerated growth as it relates to long-term neurocognitive consequences. Currently, TPO antibody status is not assessed as part of the standard prenatal care laboratory work-up, but findings from this study suggest that fetal brain growth may be impaired by TPO positivity among certain populations, therefore autoantibody screening among high-risk sub-groups may be useful for clinicians to determine whether prenatal thyroid treatment is warranted.

Only every ninth first-former ate vegetables daily, children consumed fruit too little. The majority of first-formers rarely consumed fizzy drinks, pizzas, French fries... [to full text]

This diploma thesis deals with the topic of hidden malnutrition in patients with advanced stage of ovarian carcinoma. Tumor diseases are often accompanied by malnutrition. In the case of ovarian cancer, malnutrition may be hidden, primarily due to ascites, which can distort body weight. Out of the patients included in this study 32 % had ascites. The basic nutritional status test in hospitals is the nutritional screening performed on each hospitalized patient to detect the risk of malnutrition. Other methods such as anthropometric measurements, laboratory values, bioimpedance analysis, or less commonly, imaging processes can also be used to detect malnutrition. The aim of this thesis was to evaluate whether nutritional screening and regular weight control in patients with advanced ovarian cancer is sufficient to diagnose malnutrition. The results have shown that the inclusion of anthropometric measurements between routine screening can be beneficial in detecting a greater number of malnourished patients. Also shifting the BMI threshold in nutritional screening for patients over 65 would greatly increase the capture of patients at risk of malnutrition. The secondary focus was to find whether the presence of ascites can be a determining factor in malnutrition being left undiagnosed, and which simple...

In the last twenty years as riverine comes passing accelerated hum transition process any lifestyle, generating an increase in chronic non-communicable, especially for systemic arterial hypertension. Objective: To analyze the risk factors of hypertension of the riverine communities São Francisco and Novo Renascer, the island of Marchantaria, the city of Iranduba, State of Amazonas. Methodology: Data collection was performed in the period 08 July to 24 September 2015, with 123 bordering two communities of the island of Marchantaria, municipality of Iranduba, Amazonas. Were carried out measurement of weight, height, waist circumference and waist-hip ratio, it was checked blood pressure and performed interview for survey socioeconomic riverine level. Data were analyzed for Epi Info Program 7. Results: The results showed that in the communities study the male was majority. There was not significant association between hypertension and income. There was a negative correlation between hypertension and the level of education, both in the general population of male and female, in the divided by ages. In the analysis of marital status, there was no statistical difference for the variable marital status in your correlation with hypertension. Hypertension prevalence was 59.09% for people of the community São Francisco and 40% of the people Community Novo Renascer. In two communities, the values the anthropometric measures and blood pressure measures do not have significant differences between them, although values above the recommended by Brazilian Ministry of Health. Conclusions: The riverine residents in the Island Marchantaria, whether the community of São Francisco or Novo Renascer had equivalent prevalence of borderline blood pressure and hypertension. Risk factors for both communities, with respect to age and sex, is related to the anthropometric measures with overweight and blood pressure measures above the recommended maximums. There was smoking correlated with systemic arterial hypertension, with the highest rate in the elderly of both communities. Finally, we conclude the hypertension is a serious public health problem that afflicts riverine people, which guides the need for implementation of public health policies for health promotion and prevention of hypertension geared to riverine communities. / Introdução: Estudos epidemiológicos sobre a hipertensão arterial sistêmica são de grande importância para o conhecimento das condições que influenciam o adoecimento da população. No último vincênio, as comunidades ribeirinhas vêm passando um acelerado processo de transição no estilo de vida, gerando o aumento das doenças crônicas não transmissíveis, com destaque para a hipertensão arterial sistêmica. Objetivo: Analisar os fatores de risco para hipertensão arterial sistêmica de ribeirinhos das comunidades São Francisco e Novo Renascer, da Ilha da Marchantaria, do município de Iranduba, estado do Amazonas. Metodologia: A coleta dos dados foi realizada no período de 08 de julho a 24 de setembro de 2015, com 123 ribeirinhos de duas comunidades da Ilha da Marchantaria, município de Iranduba, Amazonas. Foram realizadas mensuração do peso, altura, circunferência da cintura e da relação cintura-quadril, foi verificada a pressão arterial e realizada entrevista para levantamento do nível socioeconômico dos ribeirinhos. Os dados foram analisados pelo programa Epi Info 7. Resultados: Os resultados mostraram que, nas comunidades em estudo, o sexo masculino foi maioria. Não houve associação significante entre HA e renda. Houve correlação negativa entre HAS e o nível de escolaridade, tanto na população geral de sexo masculino e feminino, quanto na dividida por idades. Na análise da situação conjugal, não houve diferença estatística para a variável situação conjugal em sua correlação com HA. A prevalência de HAS foi de 59.09% para pessoas da Comunidade de São Francisco e 40% para as pessoas da Comunidade Novo Renascer. Nas duas comunidades, os valores do IMC, RCQ e do CP não tiveram diferenças significativas entre elas, apesar do IMC e RCQ apresentarem valores acima dos preconizados pelo Ministério da Saúde. Conclusões: Os ribeirinhos residentes na Ilha da Marchantaria, independentemente de serem da Comunidade de São Francisco ou Novo Renascer apresentaram prevalência equivalente de pressão arterial limítrofe e hipertensão arterial sistêmica. Os fatores de risco para as duas comunidades, em relação a idade e sexo, estão relacionados ao índice de IMC com a classificação de sobrepeso e RCQ acima dos valores máximos preconizados. Houve correlação do tabagismo com HAS, com maior índice nas pessoas idosas de ambas comunidades. Por fim, conclui-se a hipertensão arterial sistêmica é um grave problema de saúde pública que aflige pessoas ribeirinhas, o que norteia a necessidade de implementação de políticas públicas de saúde de promoção da saúde e prevenção da hipertensão arterial sistêmica voltadas às comunidades ribeirinhas.

Sports vision gained attention in the late 90’s and has since been the focus of many research studies. Thus far sports vision research has effectively succeeded in determining the importance of visual skills and also discovering the ability to improve visual skills through training. It is this ability to enhance visual skill performance that has led to the development of vision training programmes. However, the effectiveness of these training programmes is far from unanimous with many studies yielding inconclusive results. Possible reasons for this are the lack of scientific measures implored, testing and training of skills that are not specific to the subjects and training programmes that are unrealistic. Another major area that is missing from sports vision research is the accountability of external variables like; lifestyle, anthropometric and cardiac measurements. Aspects such as; stress, nutrition and hypo/hypertension are proposed to either have an enhancing or declining effect on visual skills. These relationships have not been scientifically tested and remain undefined. It is also important to note that research has thus far been limited to athletes. This study therefore aimed to determine the effect of two different training programmes on the visual skill performance of university students. Furthermore, external variables are determined to certify that visual skill training alone would improve visual skills and to determine and define if any relationships exist between visual skills and external variables. In order to meet the aims of this study, volunteer university students underwent pre testing of specific visual skills together with lifestyle evaluations, body composition and cardiac health testing. Thereafter the total participants (n=600) were divided into three groups. Group 1 (n=169) acted as a control group with no visual training taking place in a six week period, group 2 (n=225) underwent lab-based training with a simple repetition of testing methods used as training methods and group 3 (n=205) underwent training via an internet- based training method. Thereafter all variables were tested again and statistical analysis of the data was performed. Results showed the lab-based training group having the most improvement in visual skills with all skills improving besides vergence. The Eyedrills training group also showed significant improvements in focusing, tracking and eye- hand coordination. The control group showed the least improvement in visual skills thereby ruling out the notion of improvements occurring only due to test familiarity. Significant changes occurred in a variety of the external variables across the three groups. Due to the varied results with regards to external variables, correlations between these variables and visual skill performance is still unclear and remains undefined. There is enough evidence from this study to conclude that visual skills are improved due to visual skill training. The change from the typical subject type (i.e. athletes) is important in the expansion of visual skill testing and training to other fields besides the sports one. The effect of external variables on visual skills still remains unanswered and therefore more precise research in this regard is warranted. / Dissertation (MSc)--University of Pretoria, 2014. / gm2014 / Physiology / unrestricted

Obesity significantly increases the risk of developing numerous medical conditions, besides is associated with shortened life span. The objective of this study was to evaluate the anthropometric measurements and lipid profile in adult overweight and obese subjects residents in the state of Rio Grande do Norte. The methodology was the analysis of certain biochemical parameters in serum of individuals and a physical evaluation that consisted of measurements of blood pressure and anthropometric data. In addition, the volunteers of the research answered a questionnaire about personal, social and clinical data. 1741 samples were collected, of which 432 (24,8%) were obese. Of these, 280 were selected to participate in the study, including 118 (42,1%) men and 162 (57,9%) women. Of the remaining 1309 individuals, 731 (55,8%) were overweight. Among them, 179 (24.5%) were analyzed in this study, with 56,4% female. Of the remaining 578 normal individuals, 143 were selected as controls in the research. Amid the obese, overweight and eutrophic, there were respectively 10% vs 5% vs 5,6% of diabetics, 92,1% vs 85,5% vs 68,7% of dyslipidemics and 38,6% vs 22,3% vs 15,6% of hypertensive patients. The degree of obesity presented by the participants was varied, with the majority (72,8%) fall into grade I obese, 22,9% (64) in grade II and only 4,3% (12) in grade III. Mean anthropometric participants showed statistically significant differences between groups eutrophic, overweight and obese on the BMI, WC, WHR and %BF and between sexes in CC, WHR and %BF. As the mean serum biochemical parameters to evaluate the lipid profile showed significant differences between groups eutrophic, overweight and obese, unless the exception of HDL among overweight and obese. The significance level was 5% (p <0.05) / O sobrepeso e a obesidade s?o definidos como o ac?mulo de gordura anormal ou excessivo que possa causar danos ? sa?de, aumentando expressivamente o risco de desenvolvimento de numerosas patologias, al?m de estarem associados ? diminui??o da expectativa de vida. O objetivo do presente trabalho ? avaliar as medidas antropom?tricas e o perfil lip?dico de indiv?duos adultos obesos e com sobrepeso residentes no Estado do RN. A metodologia adotada foi a an?lise de par?metros bioqu?micos determinados no soro dos volunt?rios e uma avalia??o f?sica que constou de medi??es de press?o arterial e dados antropom?tricos. Os volunt?rios da pesquisa ainda responderam a um question?rio sobre dados pessoais, sociais e cl?nicos. Foram coletadas 1741 amostras, das quais 432 (24,8%) eram de obesos. Destes, 280 foram selecionados para participar da pesquisa, entre eles 118 (42,1%) homens e 162 mulheres (57,9%). Dos 1309 volunt?rios restantes, 731 (55,8%) apresentaram sobrepeso. Dentre eles, 179 (24,5%) foram analisados nesta pesquisa sendo 56,4% do g?nero feminino. Dos 578 volunt?rios eutr?ficos remanescentes, 143 foram selecionados como controle da pesquisa. Em meio aos obesos, sobrepesos e eutr?ficos, havia, respectivamente, 10% vs 5% vs 5,6% de diab?ticos, 92,1% vs 85,5% vs 68,7% de dislipid?micos e 38,6% vs 22,3% vs 15,6% de hipertensos. O grau de obesidade apresentado pelos volunt?rios foi variado, com a maioria (72,8%; n = 204) se encaixando em obesos grau I, 22,9% (64) em grau II e apenas 4,3% (12) em grau III. As m?dias antropom?tricas dos volunt?rios indicaram diferen?as estatisticamente significantes entre os grupos eutr?fico, sobrepeso e obeso quanto ao IMC, CC, RCQ e %GC, e entre os g?neros quanto a CC, RCQ e %GC. Assim como as m?dias dos par?metros bioqu?micos s?ricos que avaliam o perfil lip?dico indicaram diferen?as significativas entre os grupos eutr?fico, sobrepeso e obeso, salvo exce??o do HDL entre os sobrepesos e obesos.

Taste is one of the crucial factors that contributes to shaping eating behaviors and is also one of the leading reasons that affects our preferences to like or dislike some foods that mainly have a bitter taste. Variation in bitter phenotype (tasters and non-tasters) could influence diet quality and in turn body weight, which overall influenced health outcomes. The objective of this study was to identify whether bitter taste phenotype status influences anthropometric measurements, body fat percentage, and eating behaviors (liking and intake) in female college students. In this cross-sectional study (n = 86), female college students aged 18 to 22 from Mississippi State University were classified into one of two groups (taster or non-taster) by means of a taste test of filter paper saturated with the bitter compound 6-n-propylthiouracil (PROP). Adiposity was measured using anthropometric measurements and body composition was measured using bioelectrical impedance analysis. A food liking survey was administrated to identify how much participants liked or disliked various foods and beverages. Dietary intake of total energy intake, macronutrients, fruits, and vegetables were evaluated using the NIH Diet History Questionnaire. Bitter phenotype status was not significantly associated with adiposity indicators; however, it was associated with food liking scores for foods that have bitter and umami tastes such as kale and mushrooms. Additionally, bitter phenotype was associated with dietary intake for total fruits and vitamin C intakes. Ethnic background was the strongest independent variable that was significantly correlated with adiposity indicators and food liking. These results suggested that while bitter taste phenotype may influence eating behaviors in certain foods, it does not affect adiposity indicators and body fat percentage.

<p>General and reproductive health and reproductive outcome were described in rural women of childbearing age (15-44 years) during 1992-93 in a cross-sectional study in Zimbabwe. Through a two-stage sampling procedure twelve villages were selected at random, and 79% of the women in the villages accepted to participate (n=1213). In a structured interview women¡¯s self-reported morbidity, socio-economic conditions, use of health care and fertility regulation methods, reproductive outcome and infertility problems were assessed. The prevalence rates of anaemia, malaria and syphilis were investigated. Retrospectively, HIV serology was anonymously assessed and associations with socio-economic conditions and morbidity were analysed. </p><p>The mean age was 28 years. Family planning was currently used by 37%. Primary and secondary infertility was reported by 0.9% and 4.4%, respectively. The perinatal mortality rate for all completed pregnancies (n=3601) was 23/1000. During the latest completed pregnancy 94% had attended antenatal care and 85% had delivered in hospitals or clinics. The self-reported complications during delivery seemed to have been cared for within the health care system. </p><p>Women perceived their health as being generally good. Mean haemoglobin (Hb) was 13.5 g/dl and only 3.4% were anaemic (Hb ¡Ü11.0 g/dl). Malaria prevalence was 5.4%, but a positive malaria test was not associated with anaemia. Syphilis prevalence was 2.2%, and a positive syphilis test increased the risk of being HIV positive three-fold (OR=3.0; 95% CI: 1.4-6.2). </p><p>The prevalence of HIV was high (22%). Women aged 15-19 had the lowest prevalence (7.6%), while the highest was found in married women aged 20-29 years (30%). The differences in HIV prevalence between the villages ranged between 8.4% and 33%. HIV positive women reported no more morbidity than HIV negative women. The low morbidity found at the time of the study indicates a fairly short duration of the HIV epidemic. </p>
