Abstract(s)
A baixa disponibilidade de energia (DE) é considerada a causa subjacente de uma série de más adaptações em atletas, incluindo função fisiológica prejudicada, baixa densidade mineral óssea (DMO) e disfunção hormonal. A 'Deficiência Relativa de Energia no Desporto’ (RED-S) advém como uma consequência da baixa disponibilidade energética (DE). A síndrome da (RED-S) é uma entidade clínica caracterizada por baixa disponibilidade de energia, que pode afetar negativamente a saúde e o desempenho de atletas masculinos e femininos, incluindo função menstrual, imunidade, taxa metabólica, saúde óssea, saúde cardiovascular, com consequências psicológicas.
O objetivo deste trabalho foi estudar a disponibilidade energética e quais as consequências que dela advêm na saúde e desempenho dos atletas, bem como identificar os mecanismos fisiológicos subjacentes que controlam o relógio circadiano destes indivíduos e a sua capacidade de se adaptarem às condições externas diárias.
Realizou-se uma revisão da literatura nos últimos 5 anos, através da pesquisa nas plataformas PubMed e Scopus, no período de janeiro de 2019 a janeiro de 2024.
Os atletas precisam ser avaliados e educados individualmente por profissionais de saúde apropriados sobre a DE e as possíveis consequências para a saúde associadas à baixa DE. Entende-se que as intervenções nutricionais selecionadas são uma maneira eficaz de melhorar a sincronização dos relógios biológicos, se o horário das refeições e do sono forem adequadamente respeitados. Pesquisas futuras são necessárias para poder avaliar a capacidade dessas intervenções nutricionais para apoiar o melhor desempenho do atleta.
Low energy availability is considered the underlying cause of several mal adaptations in athletes, including impaired physiological function, low bone mineral density and hormonal dysfunction. ‘Relative Energy Deficiency in Sport' comes as a consequence of low energy availability. The syndrome Relative Energy Deficiency in Sport is a clinical entity characterized by low energy availability, which can negatively affect the health and performance of male and female athletes, including menstrual function, immunity, metabolic rate, bone health, cardiovascular health, with psychological consequences. The goal of this work was to study the energy availability and what the consequences that arise from it on the health and performance of athletes, as well as identifying the underlying physiological mechanisms that control the circadian clock of these individuals and their ability to adapt to daily external conditions. A literature review was carried out in the last 5 years, through research on the PubMed and Scopus platforms, from January 2019 to January 2024. Athletes need to be evaluated and educated individually by appropriate health professionals about energy availability and the possible health consequences associated with low energy availability. It is understood that the selected nutritional interventions are an effective way to improve the synchronization of biological clocks if the time of meals and sleep are properly respected. Future research is necessary to be able to evaluate the ability of these nutritional interventions to support the best performance of the athlete.
