ZusammenfassungRegelmäßige körperliche Betätigung trägt zu einer gesunden Knochendichte bei, Leistungssportlerinnen in einigen Sportarten weisen jedoch eine erhöhte Prävalenz erniedrigter Knochendichte sowie vermehrt Stressfrakturen auf. Häufig liegt dem ein relatives Energiedefizit (RED), verbunden mit hoher mechanischer Belastung und intensivem Trainingsalltag, zugrunde. Das Vorliegen eines RED im Sport ist oft unterdiagnostiziert, daher hat sich eine systematische multidisziplinäre Zusammenarbeit unter Zuhilfenahme standardisierter Tests, z. B. des RED‑S CAT (Relative Energy Deficiency in Sport Clinical Assessment Tool) als hilfreich erwiesen. Therapieansätze zielen primär auf eine Behebung der negativen Energiebilanz der Patientin als auch auf psychotherapeutische Interventionen ab. Darüber hinaus kann in schweren Fällen eine medikamentöse Therapie zur Unterstützung sowohl einer ausgeglichenen hormonellen Situation als auch des Knochenstoffwechsels notwendig sein.

Background It has been noticed that Female Athlete Triad (Fat) and Relative Energy Deficiency (Red-S) in Sport are characterized by the symptoms of impaired endocrine-metabolic function and bone health in female athletes. In addition, it may be evaluated with a qualitative tool, such as Low Energy Availability in Females questionnaire (LEAF-Q) and quantitative measurements: bone mineral density (BMD), resting energy expenditure (REE), body composition, 24-hour dietary recall. Methods The aim of this study was to assess the prevalence of Triad and Red-S using the LEAF-Q in youth female football players. Additionally, the difference in the BMD, body composition, REE and energy intake (EI) were assessed between the Triad/Red-S risk and not at-risk groups. Results Almost two thirds (64.7%) of participants are classified as being at-risk for the triad according to their LEAF-Q scores. There were no statistically significant differences (p > 0.05) between most of the values among children from the analyzed groups. There was a statistically significant difference (p < 0.001) between the EI values among girls from the two analyzed groups: at-risk (1,773.18 kcal ±  232.57) and not at-risk (2,054.00 kcal ±  191.39). Girls who did not meet the energy intake recommendations were 10.00 as likely to be in the Triad/Red-S risk group. Conclusion Early identification of Fat/Red-S symptoms by screening tools such as the LEAF questionnaire is important in protecting young athletes from long-term damage due to the progression of the risk factors associated with the Fat/Red-S.

Low Energy Availability

Low energy availability (EA) is suspected to be the underlying cause of both the Female Athlete Triad and the more recently defined syndrome, Relative Energy Deficiency in Sport (RED-S). The International Olympic Committee (IOC) defined RED-S as a syndrome of health and performance impairments resulting from an energy deficit. While the importance of adequate EA is generally accepted, few studies have attempted to understand whether low EA is associated with the health and performance consequences posited by the IOC.ObjectiveThe purpose of this cross-sectional study was to examine the association of low EA with RED-S health and performance consequences in a large clinical population of female athletes.MethodsOne thousand female athletes (15–30 years) completed an online questionnaire and were classified as having low or adequate EA. The associations between low EA and the health and performance factors listed in the RED-S models were evaluated using chi-squared test and the odds ratios were evaluated using binomial logistic regression (p<0.05).ResultsAthletes with low EA were more likely to be classified as having increased risk of menstrual dysfunction, poor bone health, metabolic issues, haematological detriments, psychological disorders, cardiovascular impairment and gastrointestinal dysfunction than those with adequate EA. Performance variables associated with low EA included decreased training response, impaired judgement, decreased coordination, decreased concentration, irritability, depression and decreased endurance performance.ConclusionThese findings demonstrate that low EA measured using self-report questionnaires is strongly associated with many health and performance consequences proposed by the RED-S models.

And Performance

The term Relative Energy Deficiency in Sport was introduced by the International Olympic Committee in 2014. It refers to the potential health and performance consequences of inadequate energy for sport, emphasizing that there are consequences of low energy availability (EA; typically defined as <30 kcal·kg−1 fat-free mass·day−1) beyond the important and well-established female athlete triad, and that low EA affects populations other than women. As the prevalence and consequences of Relative Energy Deficiency in Sport become more apparent, it is important to understand the current knowledge of the hormonal changes that occur with decreased EA. This paper highlights endocrine changes that have been observed in female and male athletes with low EA. Where studies are not available in athletes, results of studies in low EA states, such as anorexia nervosa, are included. Dietary intake/appetite-regulating hormones, insulin and other glucose-regulating hormones, growth hormone and insulin-like growth factor 1, thyroid hormones, cortisol, and gonadal hormones are all discussed. The effects of low EA on body composition, metabolic rate, and bone in female and male athletes are presented, and we identify future directions to address knowledge gaps specific to athletes.

Residual Errors

The human body requires energy for numerous functions including, growth, thermogenesis, reproduction, cellular maintenance, and movement. In sports nutrition, energy availability (EA) is defined as the energy available to support these basic physiological functions and good health once the energy cost of exercise is deducted from energy intake (EI), relative to an athlete’s fat-free mass (FFM). Low EA provides a unifying theory to link numerous disorders seen in both female and male athletes, described by the syndrome Relative Energy Deficiency in Sport, and related to restricted energy intake, excessive exercise or a combination of both. These outcomes are incurred in different dose–response patterns relative to the reduction in EA below a “healthy” level of ∼45 kcal·kg FFM−1·day−1. Although EA estimates are being used to guide and monitor athletic practices, as well as support a diagnosis of Relative Energy Deficiency in Sport, problems associated with the measurement and interpretation of EA in the field should be explored. These include the lack of a universal protocol for the calculation of EA, the resources needed to achieve estimates of each of the components of the equation, and the residual errors in these estimates. The lack of a clear definition of the value for EA that is considered “low” reflects problems around its measurement, as well as differences between individuals and individual components of “normal”/“healthy” function. Finally, further investigation of nutrition and exercise behavior including within- and between-day energy spread and dietary characteristics is warranted since it may directly contribute to low EA or its secondary problems.

The Uk

The prevalence of injury in adolescent elite track and field competitors is high,1 however only one study has been conducted with UK athletes.2 Relative Energy Deficiency in Sport (RED-S), encapsulating the Female Athlete Triad, is a syndrome whereby decreased energy availability affects health and performance, potentially leading to an increased injury risk; particularly to bone (3). Calculating decreased energy availability is difficult, however identifying contributing factors, such as disordered eating and menstrual dysfunction, is more viable.3AimThis study was conducted to identify the prevalence of musculoskeletal injury, disordered eating and menstrual dysfunction in elite junior UK track and field athletes.MethodData was collected from track and field athletes ranked within the top 10 of the UK U17 rankings in 2017 or 2018, with 138 athletes participating. Participants completed a self-reported musculoskeletal injury, disordered eating and menstrual dysfunction questionnaire relating to a 12-month time period.ResultsThis study found a 12-month retrospective injury prevalence of 43.5%. 13% of participants presented with disordered eating, whilst 37.7% of female participants presented with menstrual dysfunction. There was a statistically significant difference in injury prevalence according to gender, with more male athletes sustaining an injury compared with female athletes. No differences in injury prevalence were noted according to event group, menstrual dysfunction or disordered eating. The anatomical location displaying the highest prevalence of injury was the ankle and foot (22.5%). The anatomical structure displaying the highest 12-month injury prevalence was muscle (43.6%), followed by bone (30.9%). Additionally, 21.7% of respondents reported having previously sustained a stress fracture prior to taking part in this study.ConclusionThere is a high prevalence of injuries in junior UK track and field athletes, with most injuries affecting the lower limb. Although there was no difference noted in injury risk for athletes with menstrual dysfunction or disordered eating, the prevalence of bone injuries was alarmingly high. This study indicates the requirement for future research investigating RED-S within this population.ReferenceZemper, E. Track andField Injuries. In: Caine DJ, Maffulli N. (eds).
