Dancers are an athlete population at high risk of developing iron deficiency (ID). The aesthetic nature of the discipline means dancers potentially utilise dietary restriction to meet physique goals. In combination with high training demands, this means dancers are susceptible to problems related to low energy availability (LEA), which impacts nutrient intake. In the presence of LEA, ID is common because of a reduced mineral content within the low energy diet. Left untreated, ID becomes an issue that results in fatigue, reduced aerobic work capacity, and ultimately, iron deficient anaemia (IDA). Such progression can be detrimental to a dancer's capacity given the physically demanding nature of training, rehearsal, and performances. Previous literature has focused on the manifestation and treatment of ID primarily in the context of endurance athletes; however, a dance-specific context addressing the interplay between dance training and performance, LEA and ID is essential for practitioners working in this space. By consolidating findings from identified studies of dancers and other relevant athlete groups, this review explores causal factors of ID and potential treatment strategies for dancers to optimise absorption from an oral iron supplementation regime to adequately support health and performance.
舞者是易患缺铁性贫血(ID)的高风险运动员群体。该学科的审美性质意味着舞者可能会通过饮食限制来达到身体目标。再加上高强度的训练需求,这意味着舞者容易出现与低能量状态相关的问题,这会影响营养摄入。在低能量状态存在的情况下,由于低能量饮食中的矿物质含量减少,ID 很常见。如果不加以治疗,ID 会发展成疲劳、有氧运动能力下降,最终导致缺铁性贫血(IDA)。鉴于训练、排练和表演的身体要求很高,这种进展可能对舞者的能力造成损害。先前的文献主要集中在耐力运动员的 ID 表现和治疗上;然而,对于在这一领域工作的从业者来说,关注舞蹈训练和表演、低能量状态和 ID 之间相互作用的舞蹈特定背景是至关重要的。通过整合已确定的舞者和其他相关运动员群体的研究结果,本综述探讨了 ID 的因果因素以及舞者的潜在治疗策略,以优化口服铁补充剂的吸收,从而充分支持健康和表现。
