Introdução: A Dança Desportiva (DD) é um tipo de dança, sendo atualmente considerado como um desporto dado a sua vertente competitiva. Uma nutrição equilibrada e ajustada e não apenas uma ingestão energética adequada, parece ser relevante para atingir o desempenho ideal na dança. Objetivos: Caracterizar a ingestão alimentar e o estado nutricional de atletas portugueses de DD e avaliar a sua composição corporal. Metodologia: Avaliação antropométrica de 27 dançarinos através de uma balança de bioimpedância, fita métrica e adipómetro; aplicação de um diário alimentar 24h para avaliar a sua ingestão alimentar e aplicação de um questionário - International Physical Activity Questionaire (IPAQ) - para avaliar o nível de atividade física dos dançarinos. Resultados: A maioria dos dançarinos demostrou ser normoponderal (74,1%). A massa gorda oscilou entre os 9% e os 39,9%, a massa muscular variou entre 27,6 % e 47% e a gordura visceral oscilou entre os níveis 2 e 9. Nos dias de semana/fim-de-semana os dançarinos ingeriram cerca de 1676,1 kcal por dia. A proteína representou cerca de 26,6% do valor energético total (VET), os hidratos de carbono representaram 46,3% e os lípidos 27,2%. Em dias de competição, os dançarinos ingeriram cerca de 1428,8 kcal por dia. A proteína representou cerca de 21,1% do VET, os hidratos de carbono representaram 49,3% e os lípidos 29,7%. Dezanove (70,4%) participantes foram classificados como “Muito ativo” e oito (29,6%) como “Moderadamente ativo”. Nenhum atleta foi classificado como sedentário. Discussão/Conclusão: Comparando com as recomendações nutricionais publicadas no contexto da dança desportiva, seria recomendado um reforço na alimentação dos atletas no que diz respeito aos hidratos de carbono e proteínas em dias de competição. Os atletas têm poucos cuidados com a alimentação no seu dia-a-dia e em especial em dias de competição, influenciando eventualmente a sua composição corporal e rendimento. Embora as recomendações nutricionais para outros desportos possam ser adaptadas para dançarinos, a necessidade de desenvolver diretrizes específicas para a dança desportiva é urgente.
ABSTRACT - Introduction: Dancesport (DD) is a type of dance, currently considered as a sport given its competitive aspect. Balanced and adjusted nutrition, and not just an adequate energy intake, seems to be relevant to achieve optimal dance performance. Objectives: To characterize the food intake and nutritional status of Portuguese DD athletes and assess their body composition. Methodology: Anthropometric evaluation of 27 dancers using a bioimpedance scale, measuring tape, and adipometer; application of a 24-hour food diary to assess their food intake and application of a questionnaire - International Physical Activity Questionaire (IPAQ) - to assess the level of physical activity of dancers. Results: Most dancers proved to be normal-weight (74.1%). Fat mass ranged between 9% and 39.9%, muscle mass ranged between 27.6% and 47% and visceral fat ranged between levels 2 and 9. On weekdays/weekends, the dancers ingested about 1676,1 kcal per day. Protein represented about 26,6% of the total energy value (VET), carbohydrates represented 46,3% and lipids 27,2%. On competition days, the dancers ingested about 1428,8 kcal per day. Protein represented about 21,1% of the VET, carbohydrates represented 49,3% and lipids 29,7%. Nineteen (70,4%) participants were classified as “Very active” and eight (29,6%) as “Moderately active”. No athlete was classified as sedentary. Discussion/Conclusion: Comparing with the nutritional recommendations published in the context of dancesport, it would be recommended to reinforce the athletes' diet with carbohydrates and proteins on competition days. Athletes have little care with food in their day-to-day and especially on competition days, influencing eventually their body composition and performance. Although nutritional recommendations for other sports can be adapted for dancers, the need to develop specific guidelines for dancesport is urgent.
