METHODS:4 runners diagnosed with mild unilateral AT (4M , 48.8 ± 7.5 yrs, 188.8 ± 11.2 cm, 82.5 ± 11.1 kg) performed a 5 min. treadmill run in the sports medicine clinic, as part of a larger study, with 8 IMU’s at the feet, tibia, upper legs, sacrum and sternum. Ankle and knee angles were determined at initial contact (IC) and mid stance (MS). Additional parameters that were calculated were the vertical lower leg angle at IC (VLL), peak tibial impact (PTA), peak sacral impact (PSA), push-off power (POP) (lin. velocity at toe off, TO) and internal rotation (IR) of the tibia (at TO). Parameters were determined for the injured and non-injured leg at 1-min. intervals. An independent Mann-Whitney U-test was used to test for differences within patients between the injured and non-injured leg. RESULTS: Table 1 CONCLUSIONS:The injured leg of these AT patients showed significantly different running kinematics. AT strongly affected ankle mechanics, possibly as a compensatory strategy, indicating non-full recovery of the patients. The use of IMUs to determine the recovery of AT patients quantitatively is promising. Using IMUs there is no need for 3d optical motion capture systems or an instrumented treadmill to quantify running kinematics. Future research should follow up on these measurements to identify fully recovered patients.

The effect of relative age is a topic to consider in the selection of elite athletes to ensure that a good detection of sporting talents is being carried out during the athlete's growth and maturation phase. PURPOSE: Evaluate the relationship of relative age with sport performance of elite athletes according to gender and sports modality of sports and to evaluate differences between men and women. METHODS: We analyzed the data of 1285 athletes who were selected and attended the High Performance National Center in Chile between 1992 and 2017. The athletes came from different sports disciplines which were divided into Combat Sports, Sports with Ball, Strength and Resistance and Art and Precision sports. Only athletes presenting complete data on date of birth and sports discipline were included, while all Paralympic athletes were excluded. The age of the athletes varied from 8 to 49 years old, with a total of 59.4% men. With the data of month of birth and sports discipline we organized athletes in 4 quartiles. Athletes were classified by sport discipline and gender, and statistical analysis was carried out through Chi square to see differences between the groups. RESULTS: No effect of relative age was observed in the overall sample, however there was a slight decrease in those born in the 4th quartile, with a total of 23% of the total births, without significant differences between the quartiles without variation when analyzing by gender and sports performance. Of the 4 sports disciplines, Strength and Resistance and Combat sport showed an increase of those born in the first quartil and a decrease of those born in the last 3 months of the year, without significant differences between the groups. In sports with a balloon, this effect was not observed, while in Art and Precision sports a slight increase was observed in those born in the last months. CONCLUSIONS: Although an effect of relative age was not observed in elite athletes who train in High Performance Center in Santiago, an important decrease was found in those born in the last 3 months, especially in strength and endurance and combat sports, leaving the doubt if younger athletes are being considered during the selection of sports talents and if they are having the same opportunities to compete as their peers who were born a few months earlier.

Energy deficiency in exercising women can lead to menstrual disturbances (MD). There is no gold standard to accurately estimate energy deficiency. Ratios of measured to predicted resting metabolic rate (RMR) have been used as a proxy to categorize women as energy deficient. PURPOSE: To evaluate whether measured to predicted RMR ratios are predictive of amenorrhea or other MD. METHODS: We performed a cross-sectional comparison of 223 exercising women (≥2 hrs/wk, age 18-35 years, BMI 16-30 kg/m) who were ovulatory (OV), amenorrheic (AMEN), or subclinical MD (sMD) (including oligomenorrhea, anovulation, and luteal phase defects). Menstrual status was determined using urinary measures of reproductive hormones and menstrual calendars. Body composition was measured with DXA and RMR with the SensorMedics Vmax. Harris-Benedict, Cunningham, and DXA equations were used to calculate predicted HBRMR, CRMR, and DXARMR and to calculate the measured to predicted RMR ratio. ANOVA and Kruskal-Wallis tests determined group differences and logistic regression determined predictors of AMEN or any MD. Calculations of sensitivity, specificity and positive predictive value (PPV) assessed accuracy of predictions. RESULTS: Groups did not differ in lean or fat free mass. AMEN had lower body mass (p<0.01) than sMD, and lower BMI, percent body fat, fat mass (p<0.001) and measured RMR (1172 ± 21 kcal/d) (p<0.05) than OV (1227 ± 20 kcal/d) and sMD (1233.68 ± 17 kcal/d). HBRMR was lower in AMEN (1402± 8 kcal/d) vs sMD (1434 ± 9 kcal/d) (p<0.05). CRMR ratio (0.84 ± 0.01) was lower in AMEN vs OV (0.88 ± 0.01) (p<0.05), but DXARMR ratio (0.90 ± 0.01) was lower in AMEN vs both OV (0.96 ± 0.01) and sMD (0.95 ± 0.01) (p<0.01). Each ratio predicted AMEN (HBRMR: χ =4.822, p<0.05; CRMR: χ =8.708, p<0.01; DXARMR: χ =14.068, p<0.001), but only DXARMR ratio predicted any MD (χ =6.795, p<0.01). DXARMR ratio correctly identified the most women with AMEN (ppv=0.5; sensitivity= 0.49, specificity= 0.74) and with any MD (AMEN+sMD: ppv=0.75; sensitivity= 0.39, specificity= 0.75). CONCLUSIONS: Each ratio may be used to predict AMEN, but only DXARMR significantly predicts MD, regardless of severity. Similarly, DXARMR ratio correctly identified the most subjects. DXARMR ratio can be utilized to correctly identify women with AMEN or MD secondary to energy deficiency.
