“…In recent years a growing number of individuals suffering from anorexia nervosa has been observed [6,7]. However, the incident rate varies between different populations [8]. To date, no genetic mechanisms underlying AN have been established [9].…”

Introduction: Anorexia nervosa (AN) is an eating disorder characterised with extremely low weight. Adipokines are adipose tissuederived substances that show a wide spectrum of biological activities. We aimed to assess selected adipokine levels in women with AN before and after nutritional intervention. We also sought to examine whether BMI is the only confounding factor influencing adipokine assessment in AN. Material and methods: Sixty-five women participated in the study: 20 individuals with AN before any treatment, 18 AN patients after nutritional intervention lasting for at least six months, and 27 women as controls. In all participants blood collection and anthropometric measurements were performed. ELISA was used for evaluation of leptin receptor, adiponectin and its isoforms, and resistin. Leptin was assessed with RIA, and visfatin was measured with EIA assay. Results: Leptin and free leptin index (FLI) were lowest in treatment-naïve AN women. HMW-adiponectin and visfatin were enhanced in AN. Other adipokine levels showed no significant differences. When two subsets of anorexia nervosa were compared, only leptin, leptin receptor, and FLI were markedly different. When data were adjusted to BMI, leptin and FLI remained significantly different in the pre-treated AN subgroup when compared with the control group. Conclusions: Our results suggest that leptin is the most important adipokine in AN. It is also important that in our AN population leptin and FLI are the only factors that are influenced not only by the fat content. (Endokrynol Pol 2017; 68 (4): 422-429)

“…Uma situação de excessiva magreza pode conduzir a situações patológicas difíceis de controlar como a anorexia nervosa e bulimia nervosa (6) , tendo sido demonstrado que a anorexia nervosa está relacionada com hipoestrogenismo, hipoleptinemia, hipercortisolemia, redução dos níveis de IGF-1; concorrendo estes sintomas para a osteoporose (19) .…”

Desafios nutricionais de bailarinos profissionais PALAVRAS CHAVE:Dança. Nutrição. Controlo ponderal. RESUMOA dança caracteriza-se pela acentuada solicitação dos vários sistemas orgânicos na procura e manutenção de corpos funcionalmente aptos e esteticamente belos. A dança, embora seja essencialmente arte, ao procurar a máxima expressão visual e artística determina um grau de solicitação neuro-motora que obriga o corpo a elevadas exigências fisiológicas e biomecânicas. Quanto mais pesado o corpo do bailarino/a, maiores serão as forças de impacto ao solo, sendo que muitas lesões de overuse resultam de microtraumatismos frequentes que são acentuados quer pela fragilidade das estruturas mio-articulares quer pelo excessivo peso corporal. Assim, os bailarinos tendem a procurar um baixo peso corporal, o que pode promover certos comportamentos nutricionais energeticamente deficitários e tendencialmente patológicos. Défices calóricos constantes e consumos inadequados de alguns micronutrientes podem induzir estados hormonais incompatíveis quer com o rendimento funcional quer com a saúde óssea. De facto, corpos esbeltos, magros e longilíneos não podem ser procurados através de práticas nutricionais que afetem quer o rendimento quer a saúde. O bom senso, também para os bailarinos/as, é a regra de ouro nutricional. ABSTRACTDancing request different organic systems to allow the search and maintenance of an aesthetic and fully developed body. Although dance is essentially art, dancing request a high neuromotor activity, which places the body to high physiological and biomechanical demands. As much heavier the dancer's body is, higher will be not only the impact forces on the ground, but also the shock waves reverberating throughout the body.Many overuse injuries result from frequent microtrauma that are emphasised by the fragility of the myo-articular structures and excessive body weight. Therefore, dancers struggle for a low body weight that can lead to nutrition disorders and other nutritional behaviours eventually pathologic. Low energy and nutrient intakes can induce hormonal dysfunction with consequently negative impact on bone health and performance.Dance aesthetic and artistic demands emphasise on slenderness, leanness and lankiness forms of the body. These special bodies cannot be searched through deleterious nutritional practices that affect either the performance or health. Common sense is the golden rule for dancers' nutrition.

“…Cognisant of the potential detrimental aspects that go with dance, such as creating an ideal body aesthetic and perfectionism [39], dance sessions need to ensure competence and self-satisfaction can be achieved by all participants. Integrating a mixture of activities, a degree of flexibility and autonomy suitable to a range of participants and motivations can be complicated and difficult to design, implement and evaluate [14].…”

Extensive challenges are often encountered when recruiting participants to chronic exercise (training) studies. High participant burden during chronic exercise training programmes can result in low uptake to and/or poor compliance with the study. The aim of this qualitative study was to identify factors affecting adolescent girls' recruitment and adherence to chronic exercise training research studies. Twenty-six adolescent girls (aged 12 to 15 years) participated in one of five focus groups discussing recruitment and retention to exercise physiology research involving a chronic exercise training programme. A thematic analysis was used to analyse the data and eight final themes were inductively identified. Seven evidence-based practical recommendations are suggested to improve the recruitment and retention of participants for prospective, chronic exercise training studies. Successful recruitment requires: (i) the defining of exercise-related terms; (ii) appropriate choice of recruitment material; and (iii) an understanding of participant motivations. Retention strategies include: (iv) regular monitoring of participant motives; and (v) small groups which foster peer and researcher support. Finally, (vi) friendship and ability groups were favoured in addition to (vii) a variety of activities to promote adherence to an exercise training programme.
