Triathlete with Multiple Stress Fractures in the Lower Limbs: Case Report and Literature Review / Triatleta com múltiplas fraturas por estresse nos membros inferiores: Relato de um caso e revisão da literatura

Abstract Recurrent stress fractures rarely affect the same athlete. We present the case of a female triathlete who suffered multiple stress fractures in both tibias, the right fibula, and the left femoral neck. Conservative treatment was instituted in all episodes, with rest, reduced training load, and physical therapy rehabilitation. The relative energy deficiency in sport syndrome, along with an eating disorder, training overload, and osteopenia, was identified as a risk factor. Although rare, multiple stress fractures can occur in female triathletes. These patients must be screened for risk factors associated with biomechanics, nutrition, and training to develop an effective prevention and treatment program.

Resumo Fraturas por estresse recorrentes num mesmo atleta são raras. Apresentamos o caso de uma triatleta que sofreu múltiplas fraturas por estresse na tíbia bilateral, na fíbula direita e no colo femoral esquerdo. O tratamento conservador foi instituído em todos os episódios, com repouso, redução da carga de treino e reabilitação fisioterápica. Foi identificada como fator de risco a síndrome da deficiência energética relativa no esporte, com distúrbio alimentar, sobrecarga de treino e osteopenia. Mesmo que seja raro, múltiplas fraturas por estresse podem ocorrer em mulheres triatletas, nas quais é importante avaliar os fatores de risco associados à biomecânica, nutrição e ao treinamento para arquitetar um programa de prevenção e tratamento efetivos.

Cultural adaptation and validation of the low energy availability in females questionnaire (leaf-q) / Adaptación cultural y validación del low energy availability in females questionnaire (leaf-q) / Adaptação cultural e validação do low energy availability in females questionnaire (leaf-q)

ABSTRACT Introduction: Low energy availability, amenorrhea and osteoporosis make up the Female Athlete Triad observed in physically active females and athletes. The Low Energy Availability in Females Questionnaire (LEAF-Q) was created with the purpose of identifying female athletes at risk for the Female Athlete Triad. Objective: To translate and culturally adapt the LEAF-Q for Brazilian Portuguese and validate it in a group of Brazilian athletes. Methods: The first stage of the study consisted of translation, cultural adaptation and content validation of the questionnaire in 20 athletes. In the second stage, for the test-retest reliability analysis and the construct validation, the final adapted version was applied in a sample of 127 athletes from various sports disciplines, 54 of whom responded to the questionnaire on a second occasion. For the test-retest reliability analysis, the intraclass correlation coefficient (ICC) was calculated and the paired t-test, McNemar's test and Bland-Altman plot were carried out. The construct validation modeled by known or contrasted groups was carried out by comparing the mean LEAF-Q scores of group 1 (athletes who practiced weight-sensitive sports) with those of group 2 (athletes who practiced team sports) using the Student's t test. Results: The Brazilian version of the LEAF-Q showed excellent test-retest reliability, with an ICC of 0.92. The construct validity by known or contrasted groups was confirmed after demonstrating that athletes who practiced weight-sensitive sports had a higher LEAF-Q mean score than athletes who practiced team sports (p≤0.05). Conclusion: The Brazilian version of the LEAF-Q is an important tool, which presented textual and cultural adequacy, proved to be reliable in terms of test-retest reliability, and presents evidence of validity to investigate the risk of the triad.

The Female Athlete Triad/Relative Energy Deficiency in Sports (RED-S) / A tríade da atleta feminina/déficit energético relativo no esporte (RED-S)

Abstract In a healthy athlete, the caloric intake is sufficient for sports energy needs and body physiological functions, allowing a balance between energy availability, bone metabolism, andmenstrual cycle.Onthe other hand, an imbalance causedby low energy availability dueto a restrictive diet, eating disorders or long periods of energy expenditure leads to multisystemic deregulation favoring the essential functions of the body. This phenomenon, described as the female athlete triad, occurs in a considerable percentage of high-performance athletes, with harmful consequences for their future. The present review was carried out based on a critical analysis of themost recent publications available and aims to provide a global perception of the topic relative energy deficit in sport (RED-S). The objective is to promote theacquisition ofmore consolidated knowledgeon an undervaluedtheme, enabling the acquisition of preventive strategies, early diagnosis and/or appropriate treatment.

Resumo Emumaatleta saudável, oaporte calórico é suficientepara anecessidade energética esportiva e para as funções fisiológicas corporais, permitindo um equilíbrio entre disponibilidade energética (DE), metabolismo ósseo e função menstrual. Por outro lado, um desequilíbrio devido à baixa disponibilidade energética (BDE) por dieta restritiva, perturbações alimentares ou grandes períodos de gasto energético conduz a uma desregulação multissistêmica priorizando as funções essenciais do corpo. Este fenômeno, descrito inicialmente como tríade da mulher atleta e, atualmente, comodéfice energético relativo no esporte (RED-S, nasigla eminglês) tem como pilares a BDE, disfunção menstrual e alterações na densidade mineral óssea (DMO), estando presente em uma percentagem considerável de atletas de alta competição, com consequências nefastas para o seu futuro a curto, médio e longo prazo. A presente revisão foi realizada a partir da análise crítica das publicações mais recentes disponíveis e pretende proporcionar uma percepção global do tema RED-S. O objetivo é promover a aquisição de um conhecimento mais consolidado sobre uma temática subvalorizada, possibilitando a aquisição de estratégias preventivas, diagnóstico precoce e/ou tratamento adequado.

Além da tríade da mulher atleta: o novo conceito de deficiência relativa de energia no esporte / Beyond the female athlete triad: the new concept of relative energy deficiency in sport

"Tríade da mulher atleta" e "deficiência relativa de energia no esporte" são afecções comuns encontradas em esportistas. Tendo como fisiopatologia a disponibilidade energética negativa, essas síndromes têm impacto negativo na saúde das atletas. Apesar de serem frequentemente discutidas entre especialistas vinculados ao mundo desportivo, ainda são pouco conhecidas entre outras especialidades. Essa revisão da literatura foi proposta com o intuito de expor o problema ao ginecologista e obstetra, considerando esses profissionais importantes aliados na prevenção e diagnóstico precoce. Da mesma maneira, a intervenção terapêutica correta minimiza os diversos prejuízos à saúde e melhora o desempenho esportivo.(AU)

"Female athlete triad" and "relative energy deficiency in sport" are conditions relatively common among women participating in sports. Its pathophysiology based on negative energy availability, these syndromes have a negative impact on the athlete's health. Although they are frequently discussed among specialists linked to the sports all over the world, a little has been known among other physicians. This literature review was proposed in order to expose the problem to the gynecologist and obstetrician, considering these professionals as important allies in prevention and early diagnosis. In the same way, the correct therapeutic intervention allows to minimizes the numerous damages to athlete's health and to improve their sports performance.(AU)

A tríade da atleta / The female athlete triad

A Tríade da Atleta (TA) é uma síndrome que se manifesta na mulher por meio da baixa disponibilidade de energia (com ou sem distúrbios alimentares), disfunção menstrual e baixa densidade mineral óssea (DMO). Geralmente, acomete pessoas envolvidas com a prática de atividades físicas que enfatizam o emagrecimento.(1,2,3) O diagnóstico pode ser feito por meio da análise do Índice de Massa Corporal (IMC) da paciente; pelo cálculo da disponibilidade de energia; exames de densitometria óssea e radiografia da coluna vertebral, associados à presença de menstruações infrequentes ou amenorreia no ciclo menstrual da paciente. A incidência da TA vem aumentando na atualidade devido à maior divulgação dos benefícios da prática esportiva e à preocupação excessiva com a estética corporal imposta pela sociedade em que vivemos. Os profissionais da saúde devem estar aptos a detectar precocemente os sinais da TA para dar início ao tratamento, uma vez que este é o fator mais importante para diminuir as severas consequências ao organismo.(3) O presente artigo tem como objetivo informar sobre a existência dessa síndrome, com destaque para os métodos diagnósticos e o tratamento.(AU)

The Athlete Triad (AT) is a syndrome that is manifested in women through low energy availability with or without eating disorders, menstrual dysfunction and low bone mineral density (BMD). Usually affects people involved in physical activities that emphasize weight loss. (1,2,3) The diagnosis can be made through the patient's Body Mass Index (BMI) analysis; by calculating the availability of energy; examination of bone densitometry and radiography of the spine associated with infrequent periods or amenorrhea in the patient's menstrual cycle. The incidence of AT is increasing today because the dissemination of sports benefits and excessive concern with body imposed by society. Health professionals must be able to detect early signs of AT to start the treatment, because is the most important factor to reduce the severe consequences on the body.(3) This article has the objective to inform health professionals about the existence of this syndrome with emphasis on diagnostic methods and treatment tools.(AU)

Pre-participation gynecological evaluation of female athletes: a new proposal / Avaliação ginecológica pré-participação da mulher atleta: uma nova proposta

Objective To propose the inclusion of a gynecological investigation during the evaluation of athletes before competitions, using a specific instrument called the Pre-participation Gynecological Examination (PPGE). Methods The study assessed 148 athletes, mean age of 15.4±2.0 years, who engaged in eight different sports modalities, and who responded to a questionnaire named Pre-Participation Gynecological Examination (PPGE), to the International Consultation on Incontinence Questionnaire - Short Form (for urinary loss), and to the Eating Attitudes Test (for eating disorders). Results Fifty percent of the participants reported irregular menstrual intervals, 23.0% did not know about sexually transmitted diseases, and 72.4% denied having, at least, an annual gynecological appointment. The study identified 18.2% who had urinary loss, and 15% presented with an increased risk of eating disorders. Moreover, 89.9% were not familiar with the occurrence of urinary incontinence in athletes and did not know that they were susceptible to the female athlete triad. A total of 87.1% of them stated that would not mention these issues to their coaches even if this would improve their health or performance. Conclusion The Pre-Participation Gynecological Examination can be considered an easy-to-apply instrument that allowed the diagnosis of alterations often underestimated by the athletes themselves. After its application, the alterations were identified, and determined the athletes’ referral to appropriate evaluation and treatment. .

Management of Low Bone Mass in Female Athletes / 고신대학교의과대학학술지

As female athletic participation has increased, the positive effects of exercise on health have become evident. However, with this growth in sports activity, a set of health problems unique to the female athlete has emerged. The female athlete triad and its components can occur in females of all ages in every sport. The Female Athlete Triad poses serious health risks, both short and long term, to the overall well-being of affected individuals. Sustained low energy availability can impair health, causing many medical complications within the skeletal, endocrine, cardiovascular, reproductive, and central nervous systems. With the surge of females participating in athletics within the past 10 to 15 years, it is both conceivable and likely that the prevalence of this syndrome will continue to grow. Therefore, it is imperative that appropriate screening and diagnostic measures are enacted by a multidisciplinary team of health care providers, counselors, teachers, and dieticians in order to provide the proper care to affected athletes. Initial awareness should take place within the educational confines of elementary and high schools. Screening for female athletes exhibiting risk factors for the triad should also take place at the time of sports physicals. If one component of the triad is identified, the clinician should take the time to effectively workup the other. Treatment for each component of the triad includes both pharmacological and nonpharmacological measures, with emphasis placed upon increased energy availability and overall improved nutritional health. Using this all-encompassing type of approach, sports medicine practitioners should feel empowered to continue to promote the lifelong well-being of female athletes in the years to come.

Female and Sports / 한양의대학술지

The past three decades have seen a dramatic increase in female participation in athletics. The presentation of female athlete in 2008 Beijing Olympic Game increased up to 42.4% of total competitors. Despite the increased participation in female athletics, sports medicine research focusing on female athletics is still in its early stages. The unique anatomic, physiologic, and biomechanical characteristics of female need special attention. In general, females are shorter in stature, shorter femur, wider pelvis, larger knee valgus, narrower shoulder, and more lax in soft tissue. Females tend to have more fat, less muscle mass, and lower bone mineral density than equally trained males. Female athletes also have a concern about the pregnancy and cyclic hormonal changes with menstruation. The important musculoskeletal conditions for female athlete are scoliosis, shoulder instability and frequent knee problems including anterior cruciate ligament injury. Medically, female athlete triad composed with disordered eating, athletic amenorrhea, and premature osteoporosis is a major problems to evaluate and needs the early management.

CHANGES IN SALIVA DEHYDROEPIANDROSTERONE IN FEMALE FOOTBALL PLAYERS DURING COMPETITIVE SPORTS / 体力科学

[Objective] The aim of this investigation was to evaluate salivary dehydroepiandrosterone (DHEA) responses during a competitive period among female football players.<BR>[Methods] Subjects were college female football players (n=9) . Saliva and blood samples were collected at 18 : 00 (6 : 00 pm) and the profile of mood state (POMS) was recorded during a period of normal training (Pre), 3 days of competition (Competition), and a recovery period (Post) . Levels of salivary DHEA, cortisol, and serum creatin kinase (CK), urea nitorogen (UN), were determined.<BR>[Results] The levels of salivary DHEA significantly increased during competition (2 nd days) compared with Pre (p<0.05), and significantly decreased after competition compared with Pre (p<0.05) . The levels of salivary cortisol significantly increased during the competition (2 nd and 3 rd days) compared with Pre (p<0.05) . Whereas it decreased after competition compared with Pre. The levels of serum CK significantly increased during the competition (2 nd days) compared with Pre (p<0.05) . The levels of serum UN did not change during the study. The fatigue score of POMS significantly increased during competition (2 nd days) compared with Pre (p<0.05) .<BR>[Conclusion] These data suggest that DHEA could be a useful endocrinological indicator for evaluating training status in female athletes.

Decrease of pulsatile gonadotropin secretion in female athletes / 体力科学

Ten athletic women (5 normal ovulatory cycles, 5 short luteal phases) and 6 non-athletic women with normal ovulatory cycles were subjected to an investigation of episodic gonadotropin secretion. In the middle follicular phase, blood samples were obtained via an indwelling venous catheter every 15 minutes for 4 hours.<BR>Mean levels of gonadotropins in both athletic groups were lower (p<0.001) than in the control group. LH pulse frequencies in the short luteal group were significantly lower than in the control group (p<0.001) . LH pulse amplitudes were similar in all groups. FSH dynamics were the same as those for LH.<BR>In athletic women, low mean levels and infrequent episodic secretion of gonadotropins were obvious. These data suggest that strenuous athletic activity may cause hypothalamic-pituitary insufficiency, especially that of hypothalamic origin.
