Hyponatremia in Endurance Athletes

The purpose of this paper was to identify the relationship between hyponatremia, or water intoxication, and endurance athletes. Athletic trainers and paramedics must be educated about this potentially fatal problem and be able to determine the appropriate treatment for a hyponatremic athlete.

The role of the National Audit Office in Private Finance Initiative endurance

The Private Finance Initiative (PFI) has become one of the UK’s most contentious public policies. Despite New Labour’s advocacy of PFI as a means of achieving better value for money, criticisms of PFI have centred on key issues such as a lack of cost effectiveness, exaggerated pricing of risk transfers, excessive private sector profits, inflexibility and cumbersome administrative arrangements. Nevertheless, PFI has persisted as a key
infrastructure procurement method in the UK and has been supported as such by successive governments, as well as influencing policy in the Republic of Ireland and other European Nations. This paper explores this paradoxical outcome in relation to the role played in the UK by the National Audit Office (NAO). Under pressure to justify its support for PFI, the Blair government sought support for its policies by encouraging the NAO to investigate issues relating to PFI as well as specific PFI projects. It would have been expected that in fulfilling its role as independent auditor, the NAO would have examined whether PFI projects could have been delivered more efficiently, effectively or economically through other means. Yet, in line with earlier research, we find evidence that the NAO failed to comprehensively assess
key issues such as the value for money of PFI projects, and in so doing effectively acted as a legitimator of PFI policy. Using concepts relating to legitimacy theory and the idea of framing, our paper looks into 67 NAO private finance reports published between 1997 and 2011, with the goal of identifying the preferences, values and ideology underpinning the
NAO’s view on PFI during this period. Our analysis suggests that the NAO sought to legitimise existing PFI practices via a selective framing of problems and questions. Utilising a longitudinal approach, our analysis further suggests that this patterns of selective framing persisted over an extended time period during which fundamental parameters of the policy (such as contract length, to name one of the most important issues) were rarely addressed.
Overall the NAO’ supportive stance toward PFI seems to have relied on 1) a focused on positive aspects of PFI, such as on time delivery or lessons learned, and 2) positive comments on aspects of PFI that were criticised elsewhere, such as the lack of flexibility of underlying contractual arrangements. Our paper highlights the possibility that, rather than providing for a critical assessment of existing policies, national auditing bodies can
contribute to the creation of legitimatory environments. In terms of accounting research we would suggests that the objectivity and independence of accounting watchdogs should not be taken for granted, and that instead a critical investigation of the biases which can characterise these bodies can contribute to a deeper understanding of the nature of lobbying networks in the modern state.

Aerobic endurance in HIV-positive young adults and HIV-negative controls in Malawi

Background Aerobic endurance is an important aspect of physical fitness that enables individuals living with HIV to endure in the work place as well as in agricultural operations in order to earn a living and improve their quality of life. However, despite high HIV prevalence rates, the aerobic endurance status of young Malawians living with HIV remains unknown. The objective of this study was to determine the difference in VO2max between HIV-negative and HIV-positive individuals in Blantyre, Malawi. Methods Fifty five participants (17 males and 38 females) who have HIV and were not taking antiretroviral medication and 78 HIV-negative participants (45 males and 33 females) performed the Rockport submaximal treadmill exercise test. Measures of body weight, post-exercise heart rate and time to walk one mile were obtained and used to predict VO2max. Comparisons between groups were adjusted for age differences using analysis of covariance (ANCOVA). Results VO2max was significantly lower in HIV-positive subjects [31.1, 28.7 - 33.5mL.kg-1.min-1(mean, 95% CI)] compared with HIV-negative subjects [56.2, 54.3 - 58.1mL.kg-1.min-1]. Conclusion Aerobic endurance was markedly reduced in HIV-positive participants compared with HIV-negative participants. Findings of the current study implicate factors associated with the HIV infection as contributors to a decreased aerobic endurance in people living with HIV.

Efeito de um programa de exercícios para prevenção da dor lombar ao nível do endurance e co-ativação bilateral do músculo médio glúteo, sway postural e intensidade da dor

INTRODUÇÃO E OBJETIVOS: A dor lombar (DL) é considerada um dos maiores problemas socioeconómicos dos países industrializados e está associada à manutenção da posição de ereta em atividades ocupacionais e laborais. O objetivo do presente estudo é descrever e analisar o efeito de um programa de exercícios para prevenção da DL ao nível do endurance e co-ativação bilateral do músculo médio glúteo (MG), sway postural e a intensidade da DL em indivíduos que desenvolvem dor (DD) numa tarefa prolongala em pé. É expetável que os indivíduos DD, após o programa de exercícios, reduzam a intensidade subjetiva da dor, o nível de co-ativação bilateral e o sway postural e que aumentem o endurance do músculo MG. MATERIAIS E MÉTODOS: Os participantes (19 homens, 31 mulheres), sem história prévia de DL, foram sujeitos ao teste de indução de DL transitória. Antes do teste foi avaliado o endurance da musculatura lombo-pélvica pelo side-bridge teste (SBT); e durante o teste foram recolhidos dados da atividade do músculo MG através de eletromiografia (EMG) de superfície, avaliado o sway postural com recurso a um acelerómetro 3D e intensidade subjetiva da dor, pela EVA. Um aumento>10mm na EVA durante o teste categorizou os indivíduos como DD. Os participantes foram aleatoriamente distribuídos por sexo e por desenvolver ou não dor (DD/NDD) em grupo experimental (Exp) e controlo (Cont). O grupo Exp realizou um programa e exercícios no domicílio e o grupo Cont manteve as suas atividades. Após 4 semanas procedeu-se à reavaliação. RESULTADOS: Os individuos que constituem a amostra deste estudo foram agrupados de acordo com diversos critérios e avaliados vários aspectos relacionados com a DL. Os resultados revelaram que 48% dos participantes foram classificados como DD. Em muitos aspectos analisados, o comportamento dos indivíduos foi semelhante não existindo diferenças significativas (p≥0,05). No entanto, os resultados mostram que existem diferenças quanto à intensidade subjetiva da dor onde se obteve uma variação significativa entre os dois dias de teste (p<0,05) em indivíduos DDExp. Também se observou um efeito clinicamente relevante na interação da intervenção e sexo enquanto medidas repetidas ao nível do endurance. CONCLUSÕES: O programa de exercícios provou ser benéfico na redução da intensidade da dor durante uma tarefa prolongada em pé. O endurance muscular revelou uma variação positiva ao exercício. Nos participantes em estudo não houve alteração relevante nas medidas de co-ativação muscular e sway postural.
