    Background: The prevalence of low bone mineral density (BMD) among female athletes is higher than that among their male counterparts up to 40%. Low BMD increases the risk of stress fractures. Purpose: To examine factors associated with low BMD in female athletes, and to develop, test, and evaluate a Pre-screening Tool for Early Detection of Low BMD in Female Athletes (PreST-LBMD). Method: The development and validation groups (381 and 233 subjects, respectively) underwent a medical interview and a BMD test at the lumbar spine using dual-energy X-ray absorptiometry (DXA). A Z-score < −1 was classified as low BMD. After extracting factors associated with low BMD from univariate logistic regression and multivariate least absolute shrinkage and selection operator (LASSO) regression analyses, each variable was scored based on the β coefficients from LASSO regression to create the PreST-LBMD. The development model was validated using receiver operating characteristic (ROC) curves. Furthermore, using external validation data, sensitivity, negative predictive value (NPV), and area under the curve (AUC) were calculated to evaluate the performance of PreST-LBMD. Result: Factors associated with low BMD included age at menarche, amenorrhea for more than 1 year during the teenage years, current duration of amenorrhea, body mass index, history of stress fractures, and exercise load. The calculated cutoff value for a high likelihood of low BMD was 3 points, with a sensitivity of 0.83 (0.79–0.88), a negative predictive value of 0.85 (0.81–0.90), and an area under the curve of 0.74 (0.67–0.81). Conclusion:  We successfully developed the PreST-LBMD, which showed promising results identifying female athletes with low BMD. Those scoring ≥3 should be assessed by DXA and evaluated for the likelihood of low BMD by the athlete’s health and performance team.

     View Summary

    Objectives: The cardiac morphology of elite athletes is related to sports disciplines and race; however, no studies have examined the effects of sports discipline on East Asian athletes. Therefore, this study aimed to assess left ventricular (LV) remodeling using transthoracic echocardiography in elite Japanese athletes and establish standard values for the indicators of the cardiac morphology of elite athletes in East Asia, considering the influence of body size. Methods: We retrospectively evaluated 1,363 elite Japanese athletes who underwent electrocardiography and transthoracic echocardiography between January 2011 and December 2021. The athletes were assigned to four sports discipline categories (skill, power, mixed, and endurance). We evaluated the differences in LV volume and mass between the groups for each sex. Results: The LV end-diastolic volume (LVEDV) and LV mass indexed to the body surface area (BSA) in the endurance group (LVEDV/BSA: 72.3 ± 11.4 mL/m2 in males and 68.7 ± 11.0 mL/m2 in females, LV mass/BSA: 121.1 ± 19.1 g/m2 in males and 106.5 ± 18.0 g/m2 in females) were significantly larger than those of any other groups. Both values were affected by sex, BSA, and endurance sport type, whereas only LV mass was affected by age. Conclusion: Cardiac remodeling is proportional to the sport type, with a significantly greater effect in athletes playing endurance sports. The remodeling is particularly evident in the left ventricle; however, the corresponding remodeling is also observed in other heart chambers. Cardiac remodeling in elite Japanese athletes is similar to that observed in elite athletes of other races, except for the changes in LV wall thickness.
