Rugby is a complex, high-intensity, intermittent, collision sport with emphasis placed on players possessing high lean body-mass and low body-fat. After an 8-12 week pre-season focused on physiological adaptations, emphasis shifts towards optimizing competitive performance and recovery through periodising player’s diets and training. In Chapter 4 the physiological demands and nutritional intakes of 45 elite rugby players were assessed during a pre-season through a battery of strength and conditioning tests, quantification of training demands using global positioning system (GPS), and two 24-hour diet recalls. Mean weekly distance covered during training was 9774 ± 1404 and 11585 ± 1810 m with a total mean weekly session RPE (sRPE) of 3398 ± 335 and 2944 ± 410 arbitrary units (AU) for forwards and backs respectively. Mean daily energy intake was 14.8 ± 1.9 and 13.3 ± 1.9 MJ, carbohydrate (CHO) intake was 3.3 ± 0.7 and 4.14 ± 0.4 g·kg-1 body mass, protein intake was 2.52 ± 0.3 and 2.59 ± 0.6 g·kg-1 body mass, and fat intake was 1.0 ± 0.3 and 0.95 ± 0.3 g·kg-1 body mass for forwards and backs respectively. Markers of physical performance (1-RM strength, speed, and repeated sprint tests) and anthropometry (body fat, and estimated lean mass) significantly improved in all players, despite players’ self-selecting a ‘low’ CHO ‘high’ protein diet. It may be speculated therefore that ‘low’ CHO ‘high’ protein intakes are appropriate to fuel the pre-season, although whether these intakes are sufficient to fuel the in-season is unknown. Once the demands of the pre-season were established, the next aim of the thesis was to examine if requirements changed during the playing season, as well as quantifying energy expenditure. In Chapter 5 in-season training load using GPS and sRPE, alongside six-day assessments of energy intake (EI) and energy expenditure (EE) was measured in 44 elite Rugby Union players. Mean weekly distance covered was 7827 ± 954 m and 9572 ± 1233 m with a total mean weekly sRPE of 1776 ± 355 and 1523 ± 434 AU for forwards and backs, respectively. Mean daily EI was 16.6 ± 1.5 and 14.2 ± 1.2 MJ, and EE was 15.9 ± 0.5 and 14 ± 0.5 MJ for forwards and backs respectively. Mean CHO intake was 3.5 ± 0.8 and 3.4 ± 0.7 g·kg-1 body mass, protein intake was 2.7 ± 0.3 and 2.7 ± 0.5 g·kg-1 body mass, and fat intake was 1.4 ± 0.2 and 1.4 ± 0.3 g·kg-1 body mass for forwards and backs respectively. All players who completed the food diary self-selected a ‘low’ CHO ‘high’ protein diet during the early part of the week which increased in the days leading up to a match. EI and EE followed an inverse trend, with expenditure exceeding intake during the first four-days of the training week and then reversed in the day leading up to competition with intake exceeding expenditure. Despite this, mean EI exceeded EE which alongside no micronutrient deficiencies, suggest that the current dietary practices of these elite rugby players seem sufficient to fuel training during the in-season, providing energy intake and CHO are increased leading up to a match. Given that intakes reported in this study are still below recommended CHO intake for elite athletes (Burke et al 2011), however, it is still possible that such intakes are not optimal for match day performance. Given that in Chapters 4 and 5 it was found that elite Rugby players appear to deliberately select a low carbohydrate intake, it was deemed important to assess match-play glycogen demands following a low (the amount self selected in chapter 4) and higher (the amount self selected leading in to competition in chapter 5) carbohydrate diet. Therefore, in Chapter 6 the metabolic and physiological demands of rugby competition was assessed in 16 professional Rugby League players following either a 6g·kg (HCHO) or 3g·kg (LCHO) CHO diet for 36-hours. Muscle biopsy and blood was collected, alongside monitoring internal and external load through GPS and heart rate. Mean distance covered was 93.7 ± 12.4 and 89.4 ± 9.8 m·min-1 in the first, and 85.3 ± 13.1 and 86.9 ± 9.7 m·min-1 in the second half for HCHO and LCHO conditions respectively. Mean %HRpeak was 82.9 ± 6.1 and 81.9 ± 7.2 % in the first and 82.5 ± 7.5 and 78.4 ± 10.5 % in the second half for HCHO and LCHO conditions respectively. Mean muscle glycogen was 448.6 ± 50.8 and 444.2 ± 81.1 mmol·kg d·w-1 pre-game, and 243.4 ± 42.5 and 297.7 ± 130.5 mmol·kg d·w-1 post-game for HCHO and LCHO conditions respectively. Results demonstrate that a competitive RL match can result in ~40% muscle glycogen depletion and that match-day performance variables did not differ between conditions. It was postulated that an absolute amount of ~600 g CHO consumed 36-hours pre-match is a recommended strategy for rugby league players, although optimal dietary strategies to refuel after rugby competition are unknown. The final aim of the thesis was to examine if the current post exercise CHO guidelines are appropriate for rugby players. In Chapter 7 the magnitude of muscle glycogen repletion after consuming an immediate, or delayed re-feed post Rugby League Match Simulation Protocol (RLMSP) was assessed in 16 university rugby league players using muscle biopsy and blood letting techniques. Muscle glycogen very likely increased 48-h post-simulation (272 ± 97 cf. 416 ± 162 mmol·kg-1d.w.) after an immediate re-feed, but changes were unclear (283 ± 68 cf. 361 ± 144 mmol·kg-1d.w.) after a delayed re-feed. Creatine Kinase (CK) almost certainly increased by 77.9 ± 25.4 % (0.75 ± 0.19) post-simulation for all players. Player Load (8 ± 0.7 AU) and %HRpeak (83 ± 4.9 %) were consistent with professional RL match-play. Time to exhaustion performance test revealed no difference between conditions. This study found that simulated RL match-play elicits lower muscle glycogen utilisation (21 cf. 40 %) despite similar player load and metabolic demands to a professional RL match. This may be attributed to the difficulties of replicating extensive structural damage and physical exertion from collisions during a simulation. It was also found that substantial muscle glycogen resynthesis was possible in the immediate dietary re-feed group despite evidence of muscle damage via increased blood proteins, indicating that with appropriate feeding strategies it is possible to replenish a damaged muscle. Taken together, this thesis has characterized the training demands and energy balance of elite rugby players during the pre-season and in-season, alongside quantifying the metabolic demands of elite rugby match-play, and the most appropriate strategies to load and replenish muscle glycogen around such exercise. Future studies must now further titrate these studies and assess muscle glycogen utilisation over a number of games whilst assessing the glycogen content of individual muscle fibre types.

The prevalence of maternal obesity is on the increase, compromising both maternal and foetal health. Previous intervention studies have been designed to limit the amount of gestational weight gain but in the absence of UK guidelines relating to optimum weight change in obese pregnancies and the negative experiences of obese women with regard to previous weight loss attempts it is reasonable to ask whether this is the most effective approach. It has been demonstrated that maternal dietary intake can impact on gestational weight gain and birth weight but there is little in the way of research into the impact that quality of diet has on outcomes. Aims: To measure the quality of maternal dietary intake and weight change against pregnancy and birth outcomes and to explore and gain insight into the lived experience of obese pregnant women with a view to informing guidelines. Methods: Pregnant women with a BMI≥35kg/m2 were recruited from antenatal clinic and asked to complete 3 day food diaries at 16,28 and 36 weeks gestation, The diaries were verified using a food atlas and analysed using Microdiet. A subset of women were then followed up and interviewed regarding their lived experience of obesity. Results: The women’s dietary intake deteriorated over the duration of pregnancy and there were significant associations between some micronutrients and pregnancy and birth outcomes. Women with a BMI 35-39.9kg/m2 were most likely to gain weight. Conclusion: The dietary intake of obese pregnant women is an important predictor of pregnancy and birth outcomes and it was demonstrated that the quality of diet significant deteriorated over the duration of pregnancy. Interventions designed to increase the quality of diet are urgently required.

Com modificações nas cadeias agroalimentares proporcionadas pela crescente demanda de produtos diferenciados, os alimentos orgânicos ganham cada vez mais destaque entre os consumidores. O crescente número de consumidores resultou ao interesse das grandes empresas em atuar na comercialização de produtos orgânicos. Com novos mercados emergindo, o setor produtivo também sofre alterações para suprir a demanda. O aumento da escala produtiva e modificações na diversificação das unidades de produção são questões comuns na agricultura. A agricultura familiar quando ofertante de produtos orgânicos pode sofrer alterações em seus sistemas produtivos quando se vincula a diferentes canais de comercialização. Neste sentido, a presente pesquisa teve o objetivo de analisar a influência das relações de agricultores com o mercado nos sistemas produtivos orgânicos de hortaliças em termos de diversificação e/ou especialização de cultivos e direcionamento da produção. Para realização da análise foram relacionados os produtores vinculados a quatro associações e duas cooperativas, que comercializam seus produtos nas redes de supermercados e na feira dos agricultores ecológicos (FAE) em Porto Alegre, Rio Grande do Sul, Brasil. O levantamento dos dados ocorreu por meio de pesquisa de campo com 49 agricultores pertencentes a estas associações e cooperativas, localizadas na região da Serra Gaúcha Os resultados possibilitaram caracterizar as unidades de produção compreendendo os aspectos familiares presentes no ambiente rural, bem como utilização da área, fatores técnicos e tecnológicos, que são utilizados de forma que promovam o sustento da família e preservem os recursos naturais. As relações dos produtores com o mercado possibilitaram distinguir três tipificações: relações de comercialização com os supermercados (RCS); relações de comercialização com as feiras (RCF); e relações de comercialização com os supermercados e com as feiras (RCSF). Possibilitou-se verificar uma tendência de maior diversificação para unidades de produção vinculadas à tipificação RCF, bem como, observar uma tendência de especialização das unidades de produção vinculadas à tipificação RCS. Até o momento as tipificações RCF e RCSF, necessitaram aumentar a quantidade produzida e a diversificação com mais frequência, e a tipificação RCS demonstra maior estimulo e capacidade para aumentar a quantidade produzida e a diversificação de produtos no futuro. A possibilidade de expansão de produção da agricultura familiar orgânica encontra-se vinculada a capacidade de produção da família, sendo que a quantidade a ser produzida dependerá da disponibilidade de área e do trabalho de seus integrantes, estando às relações com o mercado influenciando quais serão os cultivos da unidade de produção. / With changes in agri-food chains offered by the growing demand for differentiated products, organic foods are becoming more prominent among consumers. The growing number of consumers resulted to the interests of large companies to act in the marketing of organic products. With new emerging markets, the productive sector also suffers changes to meet demand. The increase in production scale and changes in diversification of production units are common issues in agriculture. Family farming when the offering of organic products may change in their production systems when it binds to different marketing channels. In this sense, the present study aimed to analyze the influence of relations with the farmers market in organic vegetable production systems in terms of diversification and / or specialization of crops and direction of production. To perform the analysis were related producers linked to four associations and two cooperatives that sell their products in the supermarket and at the fair of organic farmers (FAE) in Porto Alegre, Rio Grande do Sul, Brazil. The survey data were collected through field research with 49 farmers belonging to these associations and cooperatives, located in the Serra Gaucha region It was possible to characterize the production units comprising the familiar aspects present in the rural environment, and use of the area, technical and technological factors, which are used in order to promote family support and preserve natural resources. The relations of the producers to the market allowed distinguish three typifications: marketing relationships with supermarkets (RCS); marketing relationships with fairs (RCF); and marketing relationships with supermarkets and fairs (RCSF). Possible to verify greater diversification trend of production units linked to the definition RCF, as well as a trend toward specialization of production units linked to the definition RCS. So far, the RCF and RCSF typifications, required to increase the quantity produced and diversification more often, and the characterization RCS shows major stimulus and ability to increase the quantity produced and the diversification of products in the future. The possibility of the organic family farming production expansion is linked to family production capacity, and the amount to be produced will depend on the availability of area and the work of its members, with the market relations influencing what will be the production plant crops.

This work addresses the use of microwave techniques to determine quality parameters in cured meat. The first approach is online monitoring of weight loss in the meat curing process, which is a significant measurement for the meat industry because the weight loss is used as a method of tracking the curing process. Currently, weight loss is measured by using ordinary weighing scales, which is a time-consuming and impractical technique. Thus, a novel method is required to simplify the process by implementing an online monitoring technique. In this work, a set of microwave sensors were modelled using High Frequency Structure Simulation Software and then constructed and tested. Weight loss of the sample and change in the S11-parameter illustrated a strong linear relationship (R2 > 0.98). The prediction model then was developed using the Partial Least Squares method, which exhibited a good capability of microwave sensors to predict weight loss, with R2p (prediction) = 0.99 and root mean square error of prediction (RMSEP) = 0.41. The second approach is to determine water activity (aw) in cured meat, which is the parameter that describes available water for microorganisms and influences different chemical reactions in the product. For the cured meat industry, aw is the only moisture related measurement that is an accepted Hazard Analysis and Critical Control Point plan. This is important for safety reasons, but also for energy optimisation since curing requires controlled continuous temperature and humidity. Currently, aw is being measured by the meat industry using commercially available instruments, which have limitations, namely being destructive, expensive and time-consuming. Few attempts to develop non-destructive methods to predict aw have used X-ray systems (namely Computed Tomography), Near Infrared (NIR) and Hyperspectral Imaging (HSI). Although the techniques provided promising results, they are expensive, impractical and not commercially available for the meat industry. The results from the microwave sensors demonstrated a linear relationship (R2 = 0.75, R2 = 0.86 and R2 = 0.91) between the S11 and aw at 2.4 GHz, 5 GHz and 7 GHz, respectively. The prediction model exhibited a good capability of the sensors to predict aw (R2p = 0.91 and RMSEP = 0.0173).

Low childhood physical activity levels, and high paediatric overweight and obesity levels, carry a considerable burden to health including cardiometabolic disease, low fitness, and reduced psychosocial well-being. Numerous school- based physical activity interventions have been conducted with varied success. This thesis therefore aimed to develop and investigate the effectiveness of the Children's Health, Activity and Nutrition: Get Educated! (CHANGE!) project, which was a school-based curriculum intervention to promote healthy lifestyles using an educational focus on physical activity and healthy eating. The purpose of the formative study (Study 1) was to elicit subjective views of children, their parents, and teachers about physical activity to inform the design of the CHANGE! intervention programme. Analyses revealed that families have a powerful and important role in promoting health-enhancing behaviours. Involvement of parents and the whole family is a strategy that could be significant to ~ncrease children's physical activity levels. There is large variation in the cut-points used to define moderate physical activity (MPA), vigorous physical activity (VPA) and sedentary time, which impacts on accurate estimation of physical activity levels. The purpose of Study 2 was to test a field-based protocol using intermittent activities representative of children's physical activity behaviours, to generate behaviourally valid, population-specific cut-points for sedentary behaviour, MPA and VPA. These cut-points were subsequently applied to CHANGE! to investigate changes in physical activity (Study 3). The CHANGE! intervention resulted in positive changes to body size and VPA outcomes after follow-up. The effects were strongest among those sociodemographic groups at greatest risk of poor health status. Further work is required to test the sustained effectiveness of this approach in the medium and long-term. Further, the development of an inexpensive and replicable field- based protocol to generate behaviourally valid and population-specific accelerometer cut-points may improve classification of physical activity levels in children, which could enhance subsequent intervention and observational studies.

The work described in this thesis addresses two questions relating to benefits of dietary omega-3 fatty acids (n-3 LCPUFA). Accretion of research knowledge indicates that adequate n-3 LCPUFA intakes may be instrumental in maintaining good health throughout life, including in the optimisation of cardiovascular health. Sources of n-3 LCPUFA traditionally include fish oils but concern regarding long-term sustainability of fish stocks has led to investigation of alternative sources. Krill oil, obtained from the crustacean Euphausia superba, contains n-3 fatty acids as phospholipids and triglycerides, astaxanthin and related carotenoid pigments, and has been proposed as a more effective alternative than triglyceride oils. Some foods rich in n-3-LCPUFA, including prawns, also contain cholesterol; concern regarding possible adverse health effects of such dietary cholesterol has led to public health advice to limit intake of these potentially beneficial foodstuffs. These questions are addressed in two food intake studies in male volunteers by monitoring markers of cardiovascular health, food intake and biochemical markers of compliance. Firstly, prawns and a white fish control were compared for effects on lipoprotein profiles and other markers. Dietary supplementation with 225 g prawns daily for 4 weeks was associated with a decrease in ApoB of 7.8mg/dL compared an increase (+2.4 mg/dL) for the white fish control. Participants with BMI > 25 kg/m2 also showed a reduction in plasma TAG (0.17 mmol/L) compared with baseline following prawn intake; those receiving the control showed an increase in plasma TAG (0.30 mmol/L), a decrease in HDL-C, and increases in VLDL-C and sdLDL-C. No overall adverse effect was found for prawns compared with processed white fish. Secondly, effects were compared of fish oil and krill oil on cardiometabolic profiles of a cohort of men with metabolic syndrome, using anthropometric measurements, biochemical markers of cardiovascular health and assessments of food intake. Krill oil and fish oil at the doses used showed no overall difference in effect on MetS markers after 6 weeks; correlations between magnitude of reduction and baseline measurement were observed in both groups for TAG, fasting glucose, NEFA and sdLDL after 3 weeks on both supplements, and for glucose and cholesterol after 6 weeks of fish oil. Comparison of analytical methods was also undertaken during both studies; use of a point-of-care system using capillary blood correlated well with plasma biochemistry using venous blood, while the Hirano method for sdLDL measurement correlated favourably with more labour-intensive centrifugation techniques. Limitations of the methods used are discussed, and proposals put forward for future work, including improving compliance through the use of newly emerging technologies such as metabolomics.

Obesity is a complex condition that affects all age groups and socioeconomic strata and places significant burdens on health and social care systems in both developed and developing countries. Overeating and a lack of exercise, along with smoking and high alcohol use, are the most common causes of non-communicable diseases, which account for almost two-thirds of global deaths each year. This programme of PhD research aimed to better understand dietary and other health risk behaviours by considering the influence of evolutionary behavioural strategies, while controlling for other determinants of health risk behaviours, including childhood experience and socioeconomic variables. In the first study, young adults (n=393; aged 18-30 years) completed a bespoke self-report questionnaire and provided data on their developmental experiences and their socioeconomic environments, in addition to a range of behavioural choices and evolutionary strategies (e.g. reproductive behaviour). In the second study, a secondary analysis of the second iteration of the North West Mental Well-being Survey (NWMWBS) 2012/13 was undertaken to supplement findings from study 1. These studies were analysed using regression analysis and Latent Class Analysis. Across both studies, there was a clustering of risk behaviours. Adverse childhood experiences and lower socioeconomic status were found to be predictive of health risk behaviours, including unhealthy eating, binge drinking and smoking cigarettes. Various evolutionary behavioural strategies were found to be predictive of health risk behaviours. Reproductive strategy was found to be predictive of BMI; health offsetting was found to be predictive of risky eating behaviour and physical activity; investing behaviour was found to be predictive of BMI, general health risk taking, binge drinking, current daily smoking, and violence; altruism was found to be predictive of eating preference; trust was found to be predictive of general health risk taking, current daily smoking, and physical activity; cooperation was found to be predictive of current daily smoking; and, planning behaviour was found to be predictive of current daily smoking, and risky sexual practices. Overall, the research suggests that childhood experiences and socioeconomic inequality are key determinants of behavioural strategies, and that such strategies are likely to be adaptive.

O morador do campo não atua mais somente como produtor de alimentos, mas passou a ser pluriativo, desenvolvendo também atividades não-agrícolas, que incluem comércio e serviços. Entre as atividades que caracterizam a multifuncionalidade no uso da terra estão os empreendimentos de turismo rural, que geralmente praticam a venda direta de produtos agroalimentares locais. Essa dissertação aborda o tema turismo rural e sua relação com a pluriatividade no campo e com as cadeias agroalimentares curtas em um estudo de caso em Borborema – SP, o agroturismo Caminho Caipira. O objetivo do trabalho foi investigar como o turismo se insere no espaço rural, verificando a potencialidade do Caminho Caipira para o turismo de Borborema De maneira específica, buscou-se analisar os pontos fortes e fracos do empreendimento, identificar a participação dos agentes públicos e privados na criação e manutenção do Caminho Caipira, e elencar os elementos que caracterizam a produção artesanal do empreendimento e sua relação com as cadeias curtas de comercialização. Para tal, a pesquisa teve caráter exploratório e descritivo, com abordagem qualitativa. A coleta de dados foi feita por meio de questionários semiestruturados aplicados sob os princípios da pesquisa participante. Concluiu-se que o Caminho Caipira possui potencial no turismo de Borborema e que a adoção da venda direta foi uma conveniência baseada nos princípios de sustentabilidade e produção orgânica que obriga a sazonalidade do agroalimento. O estudo apurou que não houve apoio institucional, o que tem gerado entraves ao empreendimento. / Society transformations, in economic, social and environmental scenarios, led to a new way of working in agriculture, combining land, work and family. The residents of the field no more are only producer of food, but became pluriativos (people who words in several kinds of jobs) and also develop non-agricultural activities, including commerce and services. Among the activities that characterize the multifunctionality of land use are the rural tourism achievements, which usually practice the direct sale of local food products. This dissertation addresses the issue rural tourism and its relationship with pluriactivity in the field and with short food supply chains in a case study in Borborema - SP, the agritourism Caminho Caipira. The objective of this study was to investigate the insertion of the tourism into the rural áreas, and specifically to check the potential of Caminho Caipira for tourism of Borborema City, and the relation about the short circuits of sales. For this, the research was exploratory and descriptive qualitative approach. Data collection was made through semi-structured questionnaires on the principles of participatory research. It was concluded that the Caminho Caipira has potential for the Borborema City tourism and the adoption of direct sales was a convenience on the principles of sustainability and organic production which requires the seasonality of agroalimento. The survey also sought to identify the participation of the government in creating and maintaining the project. In this case, the study found that there was no institutional support, which has created barriers to enterprise.
