Female athletes and performing artists can present with low energy availability (LEA) from either unintentional (eg, inadvertent undereating) or intentional (eg, eating disorder [ED]) methods. Whereas LEA and ED risk have been examined independently, few researchers have examined them simultaneously. Awareness of LEA with or without ED risk may provide clinicians with innovative prevention and intervention strategies.
To examine LEA with or without ED risk (eg, eating attitudes, pathogenic behaviors) in female collegiate athletes and performing artists and compare sport type and LEA with the overall ED risk.
Cross-sectional study.
Free living in sport-specific settings.
A total of 121 collegiate female athletes and performing artists (age = 19.8 ± 2.0 years, height = 168.9 ± 7.7 cm, mass = 63.6 ± 9.3 kg) participating in equestrian (n = 28), soccer (n = 20), beach volleyball (n = 18), softball (n = 17), volleyball (n = 12), and ballet (n = 26).
MAIN OUTCOME MEASURE(S): Anthropometric measurements (height, mass, body composition), resting metabolic rate, energy intake, total daily energy expenditure, exercise energy expenditure, Eating Disorder Inventory-3 (EDI-3), and EDI-3 Symptom Checklist were assessed. Chi-square analysis was used to examine differences between LEA and sport type, LEA and ED risk, ED risk and sport type, and pathogenic behaviors and sport type.
Most (81%, n = 98) female athletes and performing artists displayed LEA and differences between LEA and sport type ((\def\upalpha{\unicode[Times]{x3B1}})(\def\upbeta{\unicode[Times]{x3B2}})(\def\upgamma{\unicode[Times]{x3B3}})(\def\updelta{\unicode[Times]{x3B4}})(\def\upvarepsilon{\unicode[Times]{x3B5}})(\def\upzeta{\unicode[Times]{x3B6}})(\def\upeta{\unicode[Times]{x3B7}})(\def\uptheta{\unicode[Times]{x3B8}})(\def\upiota{\unicode[Times]{x3B9}})(\def\upkappa{\unicode[Times]{x3BA}})(\def\uplambda{\unicode[Times]{x3BB}})(\def\upmu{\unicode[Times]{x3BC}})(\def\upnu{\unicode[Times]{x3BD}})(\def\upxi{\unicode[Times]{x3BE}})(\def\upomicron{\unicode[Times]{x3BF}})(\def\uppi{\unicode[Times]{x3C0}})(\def\uprho{\unicode[Times]{x3C1}})(\def\upsigma{\unicode[Times]{x3C3}})(\def\uptau{\unicode[Times]{x3C4}})(\def\upupsilon{\unicode[Times]{x3C5}})(\def\upphi{\unicode[Times]{x3C6}})(\def\upchi{\unicode[Times]{x3C7}})(\def\uppsy{\unicode[Times]{x3C8}})(\def\upomega{\unicode[Times]{x3C9}})(\def\bialpha{\boldsymbol{\alpha}})(\def\bibeta{\boldsymbol{\beta}})(\def\bigamma{\boldsymbol{\gamma}})(\def\bidelta{\boldsymbol{\delta}})(\def\bivarepsilon{\boldsymbol{\varepsilon}})(\def\bizeta{\boldsymbol{\zeta}})(\def\bieta{\boldsymbol{\eta}})(\def\bitheta{\boldsymbol{\theta}})(\def\biiota{\boldsymbol{\iota}})(\def\bikappa{\boldsymbol{\kappa}})(\def\bilambda{\boldsymbol{\lambda}})(\def\bimu{\boldsymbol{\mu}})(\def\binu{\boldsymbol{\nu}})(\def\bixi{\boldsymbol{\xi}})(\def\biomicron{\boldsymbol{\micron}})(\def\bipi{\boldsymbol{\pi}})(\def\birho{\boldsymbol{\rho}})(\def\bisigma{\boldsymbol{\sigma}})(\def\bitau{\boldsymbol{\tau}})(\def\biupsilon{\boldsymbol{\upsilon}})(\def\biphi{\boldsymbol{\phi}})(\def\bichi{\boldsymbol{\chi}})(\def\bipsy{\boldsymbol{\psy}})(\def\biomega{\boldsymbol{\omega}})(\def\bupalpha{\bf{\alpha}})(\def\bupbeta{\bf{\beta}})(\def\bupgamma{\bf{\gamma}})(\def\bupdelta{\bf{\delta}})(\def\bupvarepsilon{\bf{\varepsilon}})(\def\bupzeta{\bf{\zeta}})(\def\bupeta{\bf{\eta}})(\def\buptheta{\bf{\theta}})(\def\bupiota{\bf{\iota}})(\def\bupkappa{\bf{\kappa}})(\def\buplambda{\bf{\lambda}})(\def\bupmu{\bf{\mu}})(\def\bupnu{\bf{\nu}})(\def\bupxi{\bf{\xi}})(\def\bupomicron{\bf{\micron}})(\def\buppi{\bf{\pi}})(\def\buprho{\bf{\rho}})(\def\bupsigma{\bf{\sigma}})(\def\buptau{\bf{\tau}})(\def\bupupsilon{\bf{\upsilon}})(\def\bupphi{\bf{\phi}})(\def\bupchi{\bf{\chi}})(\def\buppsy{\bf{\psy}})(\def\bupomega{\bf{\omega}})(\def\bGamma{\bf{\Gamma}})(\def\bDelta{\bf{\Delta}})(\def\bTheta{\bf{\Theta}})(\def\bLambda{\bf{\Lambda}})(\def\bXi{\bf{\Xi}})(\def\bPi{\bf{\Pi}})(\def\bSigma{\bf{\Sigma}})(\def\bPhi{\bf{\Phi}})(\def\bPsi{\bf{\Psi}})(\def\bOmega{\bf{\Omega}})({\rm{\chi }}_5^2) = 43.8, P < .001). The majority (76.0%, n = 92) presented with an ED risk, but the ED risk did not differ by sport type (P = .94). The EDI-3 Symptom Checklist revealed that 61.2% (n = 74) engaged in pathogenic behaviors, with dieting being the most common (51.2%, n = 62). Most (76.0%, n = 92) displayed LEA with an ED risk. No differences were found in LEA by ED risk and sport type. Softball players reported the most LEA with an ED risk (82.4%, n = 14), followed by ballet dancers (76%, n = 19).
Our results suggested that a large proportion of collegiate female athletes and performing artists were at risk for LEA with an ED risk, thus warranting education, identification, prevention, and intervention strategies relative to fueling for performance.
女性运动员和表演艺术家可能会因无意(例如,不经意间吃得过少)或有意(例如,饮食失调[ED])的方法而出现低能量可用性(LEA)。虽然已经分别检查了 LEA 和 ED 风险,但很少有研究同时检查它们。对 LEA 伴或不伴 ED 风险(例如,饮食态度、致病行为)的认识可能为临床医生提供创新的预防和干预策略。
检查女大学生运动员和表演艺术家的 LEA 伴或不伴 ED 风险(例如,饮食态度、致病行为),并比较运动类型和 LEA 与整体 ED 风险的关系。

特定运动的自由生活环境。
121 名女大学生运动员和表演艺术家(年龄=19.8±2.0 岁,身高=168.9±7.7cm,体重=63.6±9.3kg),参加马术(n=28)、足球(n=20)、沙滩排球(n=18)、垒球(n=17)、排球(n=12)和芭蕾舞(n=26)。
人体测量学测量(身高、体重、体成分)、静息代谢率、能量摄入、总每日能量消耗、运动能量消耗、饮食障碍问卷-3(EDI-3)和 EDI-3 症状检查表。使用卡方分析检查 LEA 与运动类型、LEA 与 ED 风险、ED 风险与运动类型以及致病行为与运动类型之间的差异。

我们的研究结果表明,很大一部分女大学生运动员和表演艺术家有 LEA 伴 ED 风险的风险,因此需要教育、识别、预防和干预策略,以促进运动表现。
