The adolescent female athlete: current concepts and conundrums

The urinary bladder wall is remodeled by undulatory resistance training in female Wistar rats

Urinary stress incontinence has a high prevalence in women, with many associated risk factors, such as high impact and intensity sports due to increased intra-abdominal pressure causing stretching and weakening of the pelvic floor muscles. No previous study has investigated the effects of undulatory resistance training (URT), deemed as high impact sports's modality, on urinary bladder (UB) and tissue remodeling. Healing of tissue depends on the equilibrium of metalloproteinases (MMPs) and their inhibitors (TIMPS). We aimed to investigate the histomorphological effects of URT on UB wall. Twelve female Wistar rats were randomly divided in two groups: sedentary (SED, n = 5) and URT (n = 7). URT was performed with a ladder climbing equipment after the maximum loaded carrying test (MLCT) was carried out. The training sessions were organized in three blocks increasing the MLCT's weight each block. New MLCT were set at the end of each block. The day after the last training, the rat was euthanized and the UB was harvested and stored in formalin for later histological analysis stained with hematoxylin-eosin (HE), Masson's trichrome (MT), picrosirius-hematoxylin (PH) and resorcin-fuchsin (RF), and immunohistochemistry for metalloproteinase-1 (MMP1) and tissue inhibitor of metalloproteinase (TIMP1). UB slices of URT rats stained with HE showed changes in all UB layers, with increased thickeness of the urothelium. MT staining allowed to observe an increased collagen concentration on the lamina propria layer (LP) of URT rats. PH staining demonstrated a higher luminous intensity for collagen type I and III in lamina propria and smooth muscle layers of the UB wall in the URT group than in SED. RF staining demonstrated an increase of elastic fiber concentration on the LP and smooth muscle layer of the bladder wall in the URT group. Immunohistochemistry of UB slices showed that MMP1 and TIMP1 were immunolabeled on the LP the UB wall in URT rats, with TIMP1 showing a lighter labeling than MMP1. Therefore, the findings suggest that URT induces remodeling of the urinary bladder wall characterized by imbalance between MMP1 and TIMP1 and evoking an alteration in the connective tissue from loose to dense.

How are female rugby players affected by contact breast injuries and exercise-induced breast pain - an international survey

Female Rugby Union players were affected by contact breast injuries (CBI) and exercise-induced breast pain (EIBP). Hundred and eighty-two female Rugby players from 25 different countries reported incurring a CBI or EIBP which affected sport performance. A higher percentage of 7s players (7s: 64.3%, 15s: 51.9%) reported at least one CBI over a 12-month period. EIBP frequency, during the same period, was notably low for 7s and 15s. Sprinting, jumping and running were the most frequent activities precipitating the severest EIBP. Being tackled or tackling most frequently caused a CBI. Respondents affected by either CBI (57.3%) or EIPB (51.3%) reported always playing-on during matches despite their pain or injury. Between 19.4% and 32.1% of the respondents did not have a CBI or EIBP prevention strategy. A paucity of player knowledge on prevention strategies was noted, indicating a need for education addressing breast pain and injury among players.

Contact Breast Injuries Among Female Athletes: A Systematic Review

BACKGROUND

Robust surveillance of injury aetiology and epidemiology is recognised as fundamental for effective injury reduction and management programmes. However, while sex-specific differences in injury type and nature are noted in the literature, it is unclear if these are reflected in surveillance practices, and how the athlete is affected.

OBJECTIVE

Therefore, this study aimed to systematically review contact breast injuries (CBIs) among adult female athletes.

METHODS

The following databases were searched: PubMed, EMBASE, SPORTDiscus including MEDLINE, Web of Science and Scopus. The literature search was conducted in May 2023 and the search was limited to articles in the English and German language. Studies including female athletes, aged 18 years and above, in any sports (team or individual) at any level (amateur, semi-professional and professional), where an occurrence of CBI was documented were included. Studies were included irrespective of their investigated timeframes (e.g. the whole career, one or multiple seasons). Findings were categorised (e.g. sport, level of competition and investigated timeframe of the study) to enable possible comparisons. Case studies were excluded due to the non-generalisability of findings.

RESULTS

Of the six studies included, rugby codes (rugby union, rugby league and rugby sevens) had the highest occurrence rate (62.0%) of CBIs among eight different investigated sports (rugby codes 62.0%, softball 59.5%, Australian Football League (AFL) 51.0%, water polo 50.0%, soccer 46.7%, basketball 27.6-48.8%, volleyball 34.6%, boxing 0.0%). Between 25.6% and 62.0% of participants reported incurring a CBI and between 0.0% and 42.9% of CBIs were reported to a medical professional or support staff. The reported treatment rate for CBIs ranged between 0.0% and 2.1%, The main mechanisms for CBIs (where reported) were contact with another athlete (AFL 37.6%, rugby codes 56%) the ball (AFL 31.6%, rugby codes 25.5%) and the ground (AFL 6.6%, rugby codes 22%). Between 18.2% and 48% of the participants reported that CBIs negatively affected their performance. Risk factors increasing CBIs were positional differences, larger breast size and higher body mass index (BMI). In-season injury data collection and surveillance supported through education of both players and medical staff were identified to be of relevance for future CBI prevention. None of the studies reported incidence rate.

CONCLUSION

Despite the frequent occurrence of CBIs among female athletes, reporting and treatment remains low. Awareness and education of all stakeholders are fundamental to ensuring better breast safety in female sport. Identifying the mechanics, severity and risk factors of CBIs through thorough injury surveillance must be a focus of further research.

REGISTRATION

The study was preregistered on Open Science Framework (OSF).

Changes to breast structure and function across a woman's lifespan: Implications for managing and modeling female breast injuries

BACKGROUND

Female breasts change throughout a woman's life in response to fluctuating hormonal influences. Individuals managing active women and those modeling female breasts must understand these structural and functional changes across a female's lifespan because these changes affect breast injuries sustained by women.

METHODS

We initially review female breast structure and function and then describe how breast structure changes across a woman's lifespan. Key studies about direct contact and frictional breast injuries are then summarized. Limitations of current breast injury research, gaps in knowledge about breast injuries incurred by specific populations, and the lack of breast injury models are also highlighted.

FINDINGS

With minimal anatomical protection, it is unsurprising that breast injuries occur. Although research about breast injuries is scant, direct contact during blunt force trauma to the anterior chest wall and frictional breast injuries have been reported. There is a lack, however, of research documenting the incidence and severity of breast injuries incurred in occupational settings and in women's sports. Therefore, to design effective breast protective equipment, we recommend research to model and investigate the mechanisms and forces involved in breast injuries, particularly injuries sustained during sport.

INTERPRETATION

This unique review summarizes how female breasts change over a woman's life span, with implications for breast injuries sustained by females. Knowledge gaps about female breast injuries are highlighted. We conclude by recommending research required to develop evidence-based strategies to improve how we classify, prevent, and clinically manage breast injuries sustained by females.

SUMMARY

We review changes to the breast across a woman's lifespan, highlighting implications for managing and modeling female breast injuries.

Ultrasound Imaging-Based Methods for Assessing Biological Maturity during Adolescence and Possible Application in Youth Sport: A Scoping Review

Bone maturity is an indicator for estimating the biological maturity of an individual. During adolescence, individuals show heterogeneous growth rates, and thus, differences in biological maturity should be considered in talent identification and development. Radiography of the left hand and wrist is considered the gold standard of biological maturity estimation. The use of ultrasound imaging (US) may be advantageous; however, its validity and reliability are under discussion. The aims of this scoping review are (1) to summarize the different methods for estimating biological maturity by US imaging in adolescents, (2) to obtain an overview of the level of validity and reliability of the methods, and (3) to point out the practicability and usefulness of ultrasound imaging in the field of youth sports. The search included articles published up to November 2022. The inclusion criteria stipulated that participants had to fall within the age range of 8 to 23 years and be free of bone disease and fractures in the region of interest. Nine body regions were investigated, while the hand and wrist were most commonly analyzed. US assessment methods were usually based on the estimation of a bone maturity stage, rather than a decimal bone age. Furthermore, 70% of the assessments were evaluated as applicable, 10% expressed restraint about implementation, and 20% were evaluated as not applicable. When tested, inter- and intra-rater reliability was high to excellent. Despite the absence of ionization, low costs, fast assessment, and accessibility, none of the US assessments could be referred to as a gold standard. If further development succeeds, its application has the potential to incorporate biological age into selection processes. This would allow for more equal opportunities in talent selection and thus make talent development fairer and more efficient.

What is known from the existing literature about the available interventions for pelvic floor dysfunction among female athletes? A scoping review

BACKGROUND

Female athletes may be at higher risk of developing pelvic floor dysfunction (PFD). However, despite the great number of epidemiologic studies, the interventions have not been standardized.

AIM

The present scoping review aimed to map and summarize the literature to identify the available interventions for PFD among female athletes.

METHODS

Seven databases were searched up to May 2021. Studies considering female athletes practising sports at any performance level with any type of PFD were eligible for inclusion. Any clinical intervention and any context were considered. No language, study design, and publication type restrictions were applied. Additional studies were identified through gray literature and the reference lists of articles included. The results were presented numerically and thematically.

RESULTS

From 2625 initial records, 35 studies met inclusion criteria. The majority of articles were narrative reviews, considering athletes with urinary incontinence practising multiple or high-impact sports. Authors discussed a wide range of interventions: preventive (n = 8); conservative (n = 35), pharmacological (n = 12), and surgical (n = 10). In particular, the Pelvic Floor Muscle Training was considered in 30 studies.

CONCLUSIONS

This is the first scoping review to provide a comprehensive overview of the topic. Besides the great number of available interventions, specific programs and randomized controlled clinical trials for female athletes are still limited. Findings highlighted evident gaps in the primary research confirming that the current management is based on expert opinion. This review may be useful for the overall management, and it may represent a starting point for future research.

Vitamin D and Stress Fractures in Sport: Preventive and Therapeutic Measures-A Narrative Review

There are numerous risk factors for stress fractures that have been identified in literature. Among different risk factors, a prolonged lack of vitamin D (25(OH)D) can lead to stress fractures in athletes since 25(OH)D insufficiency is associated with an increased incidence of a fracture. A 25(OH)D value of <75.8 nmol/L is a risk factor for a stress fracture. 25(OH)D deficiency is, however, only one of several potential risk factors. Well-documented risk factors for a stress fracture include female sex, white ethnicity, older age, taller stature, lower aerobic fitness, prior physical inactivity, greater amounts of current physical training, thinner bones, 25(OH)D deficiency, iron deficiency, menstrual disturbances, and inadequate intake of 25(OH)D and/or calcium. Stress fractures are not uncommon in athletes and affect around 20% of all competitors. Most athletes with a stress fracture are under 25 years of age. Stress fractures can affect every sporty person, from weekend athletes to top athletes. Stress fractures are common in certain sports disciplines such as basketball, baseball, athletics, rowing, soccer, aerobics, and classical ballet. The lower extremity is increasingly affected for stress fractures with the locations of the tibia, metatarsalia and pelvis. Regarding prevention and therapy, 25(OH)D seems to play an important role. Athletes should have an evaluation of 25(OH)D -dependent calcium homeostasis based on laboratory tests of 25-OH-D3, calcium, creatinine, and parathyroid hormone. In case of a deficiency of 25(OH)D, normal blood levels of ≥30 ng/mL may be restored by optimizing the athlete's lifestyle and, if appropriate, an oral substitution of 25(OH)D. Very recent studies suggested that the prevalence of stress fractures decreased when athletes are supplemented daily with 800 IU 25(OH)D and 2000 mg calcium. Recommendations of daily 25(OH)D intake may go up to 2000 IU of 25(OH)D per day.

Lower urinary tract and gastrointestinal dysfunction in sportswomen: a systematic review and meta-analysis of observational studies

INTRODUCTION

The aim of this review was to assess the prevalence of gastrointestinal (GI) and lower urinary tract symptoms (LUTS) in sportswomen having high intensity training and to determine whether the type of sport might also affect LUTS and GI symptoms.

EVIDENCE ACQUISITION

A systematic review of the literature was performed by searching PubMed, CINAHL, Cochrane Library and Web of Science up to November 2018. The search strategy included several keywords concerning pelvic floor disorders, urinary dysfunction, bowel dysfunction, sportswomen, and elite sports. Inclusion criteria were studies of women who performed any kind of sport with a prevalence of LUTS and/or bowel symptoms without any restriction for age, sport modality or frequency of training. Outcomes were prevalence of LUTS and GI symptoms and meta-analyses and moderator analyses to identify risk factors for the occurrence of these symptoms in female athletes.

EVIDENCE SYNTHESIS

During the search, 1263 records were screened, 31 of which met the methodological criteria for qualitative analysis and 5 for meta-analysis. Sportswomen during daily activity showed a threefold higher risk to develop urinary incontinence (UI) than controls (OR 3.13; 95% CI: 2.39-4.00). No differences were found stratifying data for UI types. Cumulative prevalence rates were: 58.7% of all kinds of UI (daily life together with sport time), 32.8% at rest (during daily life out of sport time), 36.3% during sport time; 23% of stress urinary incontinence (SUI) during sport time versus 38.6% at rest; 11% of urge urinary incontinence (UUI) during sport time versus 17.8% at rest; 11.9% of mixed urinary incontinence (MUI) during sport time versus 20.7% at rest. Prevalence rates of GI symptoms before sport time were 57.6%, during sport competition 35.2% and 58.2% after competition.

CONCLUSIONS

All the analyzed studies showed bias. This meta-analysis indicated that competitive sport activities represent a risk factor for urinary incontinence and gastrointestinal disorders. To prevent urinary leakage athletes should be instructed to strengthen the pelvic floor muscles.

URINARY INCONTINENCE AND EXERCISE: KINESIOLOGICAL DESCRIPTION OF AN INTERVENTION PROPOSAL

ABSTRACT Introduction Research shows that symptoms of urinary incontinence are common among women who engage in physical activity. Objective To conduct a kinesiological analysis of specific exercises for the pelvic floor muscles (PFM), proposing correspondences of these postures through resistance exercises. Methods This research project is of a descriptive nature with level of evidence V. Videos and photos were taken to obtain an image for the collection of data based on the accomplishment of the specific postures. Results The kinesiological study revealed that the muscles involved in the postures of exercises targeting the prevention of urinary incontinence beyond those specific to the pelvic floor were: trunk flexors; spinal erector; adductors and hip extensors. The resistance exercises corresponding to these positions in bodybuilding apparatus were the machine hack squat; sitting adductor exercises; sitting abductor exercises; the smith machine squat and the free squat or machine squat. Conclusion This study showed that it is possible to construct correspondence between exercises for the pelvic floor muscles and resistance exercises with bodybuilding equipment and free weights. A new strategy is suggested for the physical education professional, based on resistance exercises: taking a coadjuvant approach to the treatment and prevention of urinary incontinence during physical and sports exercises. Level of evidence V, Case series.

Strength and conditioning in adolescent female athletes

Despite evidence that strength and conditioning (S&C) programs decrease injury risk and increase sport performance, young females are rarely offered S&C programs comparable to those of their male counterparts. The purpose of this study was to evaluate the current body of available literature regarding S&C in adolescent female athletes, describe potential benefits, and generate recommendations for S&C programs for female adolescent athletes. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Systematic searches of the PubMed and Google Scholar databases were conducted using the following keywords: 'female athletes,' 'injury prevention,' 'adolescent,' 'physical fitness,' 'strength,' 'female adolescent,' and 'conditioning.' Studies included in this review evaluated the effectiveness of S&C protocols and/or the habits and attitudes of coaches and athletic trainers working with female adolescent athletes. Seven articles evaluating S&C programs for the adolescent female athlete were used as the basis for this systematic review. These articles described current protocols and/or factors that should be taken into account when designing S&C programs. The identified articles focused on improving the strength of adolescent female athletes, decreasing the risk of injury, and exposing female athletes to the benefits of S&C that are routinely afforded to their male counterparts. Despite the critical potential benefits of S&C training, such as improved landing mechanics, coaches and athletic trainers do not routinely implement S&C programs for female adolescent athletes. The lack of such programs is largely due to misconceptions surrounding female athletes, such as the perception that females fear bulking up. S&C programs for adolescent female athletes should incorporate stretching of the hip adductors, targeted hamstring, gluteal and quadriceps strengthening, and a synergistic adaptation model, which tailors training protocols to an athlete's pubertal stage.

Idiopathic Granulomatous Mastitis: Manifestations at Multimodality Imaging and Pitfalls

Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory breast entity characterized by lobulocentric granulomas. IGM has a persistent or recurrent disease course and affects parous premenopausal women with a history of lactation. It has also been associated with hyperprolactinemia. The most common clinical sign is a palpable tender mass. However, the nonspecific manifestations and varied demographic features of this condition, as well as the other similar-appearing and superimposed breast entities, pose substantial diagnostic challenges. Entities with similar manifestations include inflammatory breast cancer (IBC), infective mastitis, foreign body injection granulomas, mammary duct ectasia, diabetic fibrous mastopathy, and systemic granulomatous processes. The strategy for imaging IGM depends on patient age, clinical manifestations, and risk factors. Targeted ultrasonography, mammography, and less commonly, magnetic resonance imaging have proven to be useful for imaging evaluation. Core-needle biopsy, with or without fine-needle aspiration for cytopathologic examination, and culture analysis are usually required to exclude IBC and other benign inflammatory breast processes. Patients with IGM have an excellent prognosis when they are appropriately treated with oral steroids or second-line immunosuppressive and prolactin-lowering medications. However, surgical excision may be an option for patients in whom medication therapy is unsuccessful. Imaging surveillance can be offered to patients with incidentally encountered IGM or mild symptoms. Clinical suspicion for this rare disease and the breast imager's prompt diagnosis can lead to an improved patient outcome. The purpose of this article is to review the imaging manifestations of IGM in a multimodality case-based format and to describe relevant clinical and imaging-based differential diagnoses. The associated pitfalls, epidemiologic and histopathologic factors, clinical manifestations, natural course, and management of IGM also are discussed. ©RSNA, 2018.

Prevalence and risk of sport types to stress urinary incontinence in sportswomen: A cross-sectional study

OBJECTIVE

The objective of our study was to investigate the prevalence and risk of developing stress urinary incontinence (SUI) in each type of high-intensity sport, and the associated impact on quality of life in sportswomen.

METHODS

This cross-sectional study was conducted between March and November 2016. The study included 278 sportswomen. The basic inclusion criteria were being nulliparous and engaging in high-intensity physical activity. The exclusion criteria were childbirth, surgical treatment of gynecological and urological illnesses and urinary tract infection. For evaluation were used: The International Physical Activity Questionnaire (IPAQ), The International Consultation on Incontinence Questionnaire Urinary Incontinence (ICIQ-UISF), the Overactive Bladder Questionnaire (OAB-q), the Urinary Incontinence Quality of Life Scale (I-QOL).

RESULTS

The highest percentage of SUI was found in athletes (23.8%), followed by volleyball players (19.6%). We found that cumulative metabolic equivalent (MET) did not affect SUI, but the type of sport did. The risk of SUI was highest in volleyball sportswomen (odds ratio[OR] = 2.16,95% confidence interval[CI] = 0.96-4.89, P < 0.05) and athletes (OR = 2.56,95%CI = 0.87-7.51, P = 0.08). As assessed by the I- QOL, SUI in people who participated in fitness and athletics (e.g., basketball, volleyball and handball) had a negative impact on quality of life including behavior, psychosocial impacts and social embarrassment score.

CONCLUSION

Volleyball players have a 116% chance of getting SUI compared to women who play other types of sports that were analyzed as part of this study. Healthcare professionals should inform the population of sportswomen with risk factors for SUI in order to implement preventive physiotherapy for strengthening pelvic floor muscles.

Breast Injuries in Female Collegiate Basketball, Soccer, Softball and Volleyball Athletes: Prevalence, Type and Impact on Sports Participation

Objective

In 2015-2016, over 214,000 female athletes competed at the collegiate level in the United States (U.S.). The National Collegiate Athletic Association (NCAA) collects injury data; however, breast-related injuries do not have a specific reporting category. The exact sequelae of breast injury are unknown; however, a relationship between breast injury and fat necrosis, which mimics breast carcinoma, is documented outside of sports participation. Breast injuries related to motor vehicle collisions, seatbelt trauma, and blunt trauma have been reported. For these reasons, it is important to investigate female breast injuries in collegiate sports. The objectives of this study are to report the prevalence of self-reported breast injuries in female collegiate athletes, explore injury types and treatments, and investigate breast injury reporting and impact on sports participation.

Materials and Methods

A cross-sectional study of female collegiate athletes at four U.S. universities participating in basketball, soccer, softball, or volleyball. Main outcome measure was a questionnaire regarding breast injuries during sports participation.

Results

Almost half of the 194 participants (47.9%) reported a breast injury during their collegiate career, less than 10% reported their injury to health personnel with 2.1% receiving treatment. Breast injuries reported by breast injuries reported by sport include softball (59.5%), basketball (48.8%), soccer (46.7%), and volleyball (34.6%).

Conclusions

The long-term effects and sequelae of breast injuries reported by female collegiate athletes during sport play are unknown. Nearly 50% of participants had a breast injury during sports activities. Although 18.2% indicated that breast injury affected sports participation, only 9.6% of the injuries were reported to medical personnel with 2.1% receiving treatment.

Menstrual irregularity and use of oral contraceptives in female adolescent athletes in Swedish National Sports High Schools

Objective Female adolescent athletes seem to use oral contraceptives (OCs) in the same proportion as the general population. In athletes not using OCs, menstrual irregularity (MI) is reported to be common but there are few studies of MI in adolescent athletes. The aim of the study was to survey menarche, menstrual irregularity and use of OCs in adolescent athletes in the National Sports High Schools in Sweden. A further aim was to study the associations between current sport injury and menstrual irregularity as well as use of OCs. Subjects Two hundred and ninety-eight female adolescent athletes at Swedish National Sports High Schools. Methods A web-based questionnaire containing questions related to menstrual status, contraception and current injury. Results One third (32.6%) of the athletes used OCs and of the remaining athletes 31.8% had MI. The group of athletes with MI had a significantly (p = 0.038; Cohen's d, 0.32) lower BMI and consisted of a significantly (p = 0.043) higher proportion of endurance athletes. OC users were less likely to participate in endurance sports compared to non-OC users (p = 0.024). Current injury was equally distributed in the OC and the non-OC group but athletes with MI had fewer sports injuries compared to eumenorrheic women. Conclusion OCs are frequently used among athletes at Swedish National Sports High Schools. OC users were less likely to participate in endurance sports compared to non-OC users. MI was common and athletes with MI had lower BMI compared to eumenorrheic athletes. Sports injuries were not associated with use of OC and eumenorrheic athletes had a higher proportion of current injury.

[Prevalence of iron deficiency]

Studies of prévalence in iron deficiency separate iron depletion (defined as decreased blood ferritin) and iron deficiency anemia (defined as blood decrease in both ferritin and hemoglobin). In Europe, most studies are outdated. Prevalence of iron depletion varies from 7 to 18 % and 24 to 36% in toddlers and adolescents, respectively. Prevalence of iron deficiency anemia varies from 2 to 8.5% and 7 to 10% in toddlers and adolescents. In French speaking African countries, Demography Health Surveys show that 80% of children aged 0 to 2 years are anemic, severely for 5 to 9% of them.

Are Elite Female Soccer Athletes at Risk for Disordered Eating Attitudes, Menstrual Dysfunction, and Stress Fractures?

OBJECTIVE

To determine the prevalence of stress fractures, menstrual dysfunction and disordered eating attitudes in elite female soccer athletes.

DESIGN

Cross-sectional descriptive study.

SETTING

Female soccer athletes were recruited from a national level youth soccer club, an NCAA Division I university team, and a women's professional team.

PARTICIPANTS

Two hundred twenty female soccer athletes with a mean age of 16.4 ± 4 years and BMI of 20.8 ± 2 kg/m(2) completed the study, representing all athletes from the included teams.

METHODS

One-time surveys completed by the athletes.

MAIN OUTCOME MEASUREMENTS

Height and weight were recorded, and body mass index (BMI) was calculated for each athlete. Athletes reported age of menarche, history of missing 3 or more menses within a 12-month period and stress fracture. The Eating Attitudes Test (EAT-26) was used to assess the athlete's body perception and attitudes toward eating.

RESULTS

Of the 220 soccer athletes, 3 athletes (1.6%) had a low BMI for their age, and 19 (8.6%) reported stress fractures of the lower extremity. Among athletes who had reached menarche, the average onset was 13 + 1 year; menstrual dysfunction were present in 21 (19.3%). On the EAT-26, 1 player scored in the high risk range (>20) and 17 (7.7%) scored in the intermediate risk range (10-19) for eating disorders. Athletes with an EAT-26 score ≥ 10 points had a significantly higher prevalence of menstrual dysfunction in the past year compared to athletes with an EAT-26 score of less than 10 (P = .02).

CONCLUSIONS

Elite female soccer athletes are susceptible to stress fractures and menstrual dysfunction and have delayed onset of menarche despite normal BMI and appropriate body perception and attitudes towards eating. Further studies are needed to better understand stress fracture risk in female soccer athletes and in other team sports to determine how these findings relate to long-term bone health in this population.

Non-puerperal mastitis masking pre-existing breast malignancy: importance of follow-up imaging

Mastitis is an inflammatory condition of the breast with common symptoms of pain, swelling, erythema, warmth, and fever. Diagnosis of mastitis is easily made on the basis of typical symptoms and ultrasonographic findings, such as diffusely increased echogenicity of the parenchyma and subcutaneous fat, or skin thickening. However, when it occurs in women middle-aged or older, associated malignancy should be considered. In our cases, we detected irregular hypoechoic malignant masses after the disappearance of inflammatory changes. Therefore, when non-puerperal women have inflammatory signs on their breast, follow-up imaging should be performed. In particular, in the case of persistent or growing palpability after the recovery of breast inflammation, percutaneous core biopsy and short-term follow-up with ultrasonography should be considered to exclude the associated malignancy.

Prevalence of stress urinary incontinence in elite female endurance athletes

The goal of the study was to assess the prevalence of stress urinary incontinence in a group of elite female endurance athletes, as professional sport is one of the risk factors for stress urinary incontinence. SUI rates in the groups of female cross-country skiers and runners were compared to determine whether the training weather conditions like temperature and humidity influenced the prevalence of urinary incontinence. An anonymous questionnaire was distributed among 112 elite female athletes ie., 57 cross-country skiers and 55 runners. We used a short form of the Urogenital Distress Inventory (UDI-6) to assess the presence of SUI symptoms and the level of urogenital distress. Only women who had been practicing sport professionally for at least 3 years, on an international and national level, were included in the research. The study group consisted of 76% nulliparous and 24% parous women. 45.54% of all participants reported leakage of urine associated with sneezing or coughing which indicates stress urinary incontinence. 29.46% were not bothered by the urogenital distress symptoms. 42.86% of the participants were slightly bothered by the symptoms, 18.75% were moderately bothered, 8.04% were significantly bothered and 0.89% were heavily bothered. The absence of statistically significant differences between both groups seems to indicate that training weather conditions did not influence the prevalence of SUI in elite female endurance athletes.

The LEAF questionnaire: a screening tool for the identification of female athletes at risk for the female athlete triad

BACKGROUND

Low energy availability (EA) in female athletes with or without an eating disorder (ED) increases the risk of oligomenorrhoea/functional hypothalamic amenorrhoea and impaired bone health, a syndrome called the female athlete triad (Triad). There are validated psychometric instruments developed to detect disordered eating behaviour (DE), but no validated screening tool to detect persistent low EA and Triad conditions, with or without DE/ED, is available.

AIM

The aim of this observational study was to develop and test a screening tool designed to identify female athletes at risk for the Triad.

METHODS

Female athletes (n=84) with 18-39 years of age and training ≥5 times/week filled out the Low Energy Availability in Females Questionnaire (LEAF-Q), which comprised questions regarding injuries and gastrointestinal and reproductive function. Reliability and internal consistency were evaluated in a subsample of female dancers and endurance athletes (n=37). Discriminant as well as concurrent validity was evaluated by testing self-reported data against measured current EA, menstrual function and bone health in endurance athletes from sports such as long distance running and triathlon (n=45).

RESULTS

The 25-item LEAF-Q produced an acceptable sensitivity (78%) and specificity (90%) in order to correctly classify current EA and/or reproductive function and/or bone health.

CONCLUSIONS

The LEAF-Q is brief and easy to administer, and relevant as a complement to existing validated DE screening instruments, when screening female athletes at risk for the Triad, in order to enable early detection and intervention.

Bone mineral density in elite adolescent female figure skaters

Abstract

Elite adolescent figure skaters must accommodate both the physical demands of competitive training and the accelerated rate of bone growth that is associated with adolescence, in this sport that emphasizes leanness. Although, these athletes apparently have sufficient osteogenic stimuli to mitigate the effects of possible low energy availability on bone health, the extent or magnitude of bone accrual also varies with training effects, which differ among skater disciplines.

Purpose

We studied differences in total and regional bone mineral density in 36 nationally ranked skaters among 3 skater disciplines: single, pairs, and dancers.

Methods

Bone mineral density (BMD) of the total body and its regions was measured by dual energy x-ray absorptiometry (DXA). Values for total body, spine, pelvis and leg were entered into a statistical mixed regression model to identify the effect of skater discipline on bone mineralization while controlling for energy, vitamin D, and calcium intake.

Results

The skaters had a mean body mass index of 19.8 ± 2.1 and % fat mass of 19.2 ± 5.8. After controlling for dietary intakes of energy, calcium, and vitamin D, there was a significant relationship between skater discipline and BMD (p = 0.002), with single skaters having greater BMD in the total body, legs, and pelvis than ice dancers (p < 0.001). Pair skaters had greater pelvic BMD than ice dancers (p = 0.001).

Conclusions

Single and pair skaters have greater BMD than ice dancers. The osteogenic effect of physical training is most apparent in single skaters, particularly in the bone loading sites of the leg and pelvis.
