Desafios nutricionais de bailarinos profissionais

Abstract

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.

Body Image Dissatisfaction, Eating Disorders, and Associated Factors in Brazilian Professional Ballroom Dancers

“…However, the search for excessive thinness can lead to pathological situations such as the development of eating disorders. 1,16,32 Hence the present study found an association between dissatisfaction with the percep-tion of being overweight and eating disorders, with a 3% greater chance for those professional dancers showing higher EAT scores and a 28% greater chance for those presenting higher scores on the BITE symptom scale to develop these disorders. The current literature confirms these tendencies, indicating that dancers as a population are exceptionally prone to dissatisfaction due to the perception of being overweight 17,30,31,33 and consequently to eating disorder symptoms, 3,10,16,32,34 all of which are 28% more prevalant in females than males.…”

“…D edication to a professional career in dance requires a high level of functional aptitude and an aesthetically beautiful body. 1,2…”

“…Thus, professional dancers search for maximum artistic and visual expression that is literally embodied in the demand for excellent physical qualities and great biomechanical and physiological capabilities. 1,[3][4][5] Due to intense concern with aesthetic standards, dancers tend to maintain thin bodies, [6][7][8][9] which can lead to discomfort with body image. [9][10][11] Studies have indicated that independent of sex and age, it is common for individuals, even those at their ideal weight, to be dissatisfied with their bodies.…”

A insatisfação com a imagem corporal e os possiveis distúrbios alimentares entre os praticantes de balé clássico / The dissatisfaction with body image and possible food disorders among classic ballet practice

“…A dança é uma expressão corporal e tem exigências estéticas que incentivam os seus praticantes ao controle nutricional excessivo para manter uma adequação da silhueta corporal exigida. Cada dançarino desempenha sua habilidade dentro do limite de competência fisiológica e biomecânica, destacando-se aqueles que apresentam a melhor capacidade física (LANCHA JÚNIOR, 2011;AMORIM, 2014).…”
