Osteochondritis Dissecans of the Humeral Capitellum in Young Athletes
Background:
Osteochondritis dissecans (OCD) lesions are often observed in the humeral capitellum both in young baseball players and gymnasts. It is generally believed that capitellar OCD in baseball players can be seen on an anteroposterior (AP) radiograph with the elbow in 45° of flexion. However, the mechanism of injury seems to be different in baseball players and gymnasts. Repetitive valgus overload with the elbow in flexion is believed to be the cause of capitellar OCD lesions in baseball players, whereas weightbearing with the elbow in extension may be the cause of OCD in gymnasts.
Purpose:
To determine the difference in capitellar OCD location between baseball players and gymnasts and to propose the optimal AP radiographic angle of the elbow for visualization of early-stage OCD lesions in adolescent gymnasts.
Study Design:
Cross-sectional study; Level of evidence, 3.
Methods:
Subjects consisted of 95 baseball players (95 elbows) and 21 gymnasts (24 elbows) with a mean age of 13.7 years (range, 11-18 years). To localize the lesion, inclination of the affected area in the humeral capitellum against the humeral axis was investigated using sagittal computed tomography images of the elbow. The inclination angle was defined as the angle between the long axis of the humerus and the line perpendicular to a line that connected the anterior and posterior margin of the lesion. The inclination angle in each group was compared and statistically analyzed.
Results:
The mean inclination angle was 57.6° ± 10.7° in baseball players and 28.0° ± 10.7° in gymnasts. Capitellar OCD lesions were located more anterior in baseball players when compared with gymnasts (P < .01).
Conclusion:
Due to differences in applied stress, capitellar OCD lesions in baseball players were located more anteriorly compared with those seen in gymnasts. Therefore, although AP radiographs with the elbow in 45° of flexion are optimal for detecting OCD lesions in baseball players, radiographs with less elbow flexion or full extension are more useful in gymnasts, especially in early-stage OCD.

IMPACT OF PREPARATORY PERIOD ARTISTIC GYMNASTICS TRAINING ON AEROBIC PERFORMANCE IN FEMALE GYMNASTS
elite artistic gymnasts. Eight female gymnasts (16.0 ± 2.7 years) were compared to a control group of eight untrained peers (15.9 ± .4 years). Over a 4-month preparatory period, the gymnasts underwent training focused on strength, speed, and endurance development. Anaerobic performance was assessed before and after the intervention using the Wingate test, countermovement jumps (with and without arm swing), repeated vertical jumps (10- and 60-second series), and handstand jumps on a contact mat-based ergometer. Key performance indicators included peak and mean power output, fatigue index, jump height, and blood lactate concentration. Statistical analysis was conducted using Wilcoxon T-tests for within-group and Mann-Whitney U-tests for between-group comparisons. Post-training, the gymnasts demonstrated significant improvements (p ≤ .05) in jump height, power output, and fatigue resistance across multiple tests. The control group showed no significant changes, except for a minor increase in mean power output in the 60-second jump test. These findings suggest that targeted gymnastic training during the preparatory phase effectively enhances anaerobic capacity, potentially enabling gymnasts to perform more complex elements and improve overall competitive performance. V raziskavi smo preučevali, kako posebna priprava vpliva na anaerobne sposobnosti vrhunskih telovadk v orodni telovadbi. Osem telovadk (16,0 ± 2,7 leta) smo primerjali s skupino osmih običajnih vrstnic (15,9 ± 0,4 leta). V štirimesečnem pripravljalnem obdobju so telovadke vadile z osredotočenostjo na moč, hitrost in vzdržljivost. Anaerobno zmogljivost smo pred in po vadbenem posegu ocenili z Wingateovim preizkusom, s skokom z nasprotnim gibanjem (z in brez zamaha rok), s ponavljajočimi se navpičnimi skoki (nizi po 10 in 60 sekund) ter z odrivi iz stoje na rokah na merilnem sistemu s kontaktno blazino. Glavni kazalniki so bili največja in povprečna moč, kazalnik utrujenosti, višina skoka ter delež mlečne kisline v krvi. Za primerjave znotraj skupin smo uporabili Wilcoxonov T-preizkus, za medskupinske pa Mann-Whitneyjev U-preizkus. Po vadbi so telovadke dosegle pomembna izboljšanja (p ≤ 0,05) pri višini skoka, izhodni moči in odporu proti utrujanju v več preizkusih. V primerjalni skupini ni bilo pomembnih sprememb, razen manjšega porasta povprečne moči v 60-sekundnem nizu skokov. Ugotovitve kažejo, da ciljno usmerjena telovadba v pripravljalnem obdobju učinkovito poveča anaerobno zmogljivost, kar lahko telovadkam omogoči izvedbo zahtevnejših prvin in boljši tekmovalni dosežek.

Body Composition, Dietary Intake and the Risk of Low Energy Availability in Elite-Level Competitive Rhythmic Gymnasts
The aim of this study was to analyze dietary intake and body composition in a group of elite-level competitive rhythmic gymnasts from Spain. We undertook body composition and nutritional analysis of 30 elite gymnasts, divided into two groups by age: pre-teen (9–12 years) (n = 17) and teen (13–18 years) (n = 13). Measures of height, weight, and bioimpedance were used to calculate body mass index and percent body fat. Energy and nutrient intakes were assessed based on 7-day food records. The two groups had similar percentages of total body fat (pre-teen: 13.99 ± 3.83% vs. teen: 14.33 ± 5.57%; p > 0.05). The energy availability values for pre-teens were above the recommended values (>40 kcal/FFM/day) 69.38 ± 14.47 kcal/FFM/day, while those for the teens were much lower (34.7 ± 7.5 kcal/FFM/day). The distribution of the daily energy intake across the macronutrients indicates that both groups ingested less than the recommended level of carbohydrates and more than the recommended level of fat. Very low intakes of calcium and vitamin D among other micronutrients were also noted. The main finding is that teenage gymnasts do not consume as much energy as they need each day, which explains their weight and development. Moreover, they are at a high risk of developing low energy availability that could negatively impact their performance and future health.

QUALITY OF LIFE, LEVEL OF ANXIETY AND LEVEL OF DEPRESSION AMONG FORMER ARTISTIC GYMNASTS, FORMER GYMNASTS FROM OTHER SPORTS AND NON-ATHLETES
Involving people in physical activity or sport provides some health-related benefits and has a positive effect on their quality of life (QoL). However, high level athletes experience anxiety to cope with the high demands of the sport. The purpose of the study was to assess the QοL, level of anxiety (STAI) and level of depression (BDI) among former artistic gymnasts, former athletes from other gymnastics sports (acrobatic, rhythmic, gymnastics for all) and non-athletes. Secondly, it aimed to investigate if there are gender differences within the groups on the aforementioned variables. 114 healthy people (75 women and 39 men) were involved in the present study with a mean age 27.11 ± 9.92 years. The sample was divided into 3 different groups (1st group: 39 former artistic gymnasts (FAG); 2nd group: 53 former gymnasts from other gymnastic sports (GOS), and 3rd group: 22 non-athletes (CG). Participants were asked to complete three different questionnaires in order to assess their QoL, STAI, and BDI. Statistical analysis showed no significant differences on QοL and STAI, whoever a statistically significant difference was found between groups on BDI (p <.05). No main effect was found on gender. Further, results revealed that former gymnasts, regardless of the type of sport, have better QoL, lower level of STAI and BDI compared to non-athletes. In conclusion, former gymnasts, even after years of absence from the sport, report better QoL, and have a lower level of STAI and BDI than non-athletes.

Effect of Plyometric Training on Handspring Vault Performance and Functional Power in Youth Female Gymnasts
This study aimed to determine the effect of plyometric training (PT) when added to habitual gymnastic training (HT) on handspring vault (HV) performance variables. Twenty youth female competitive gymnasts (Age: 12.5 ± 1.67 y) volunteered to participate and were randomly assigned to two independent groups. The experimental plyometric training group (PTG) undertook a six-week plyometric program, involving two additional 45 min PT sessions a week, alongside their HT, while the control group (CG) performed regular HT only. Videography was used (120 Hz) in the sagittal plane to record both groups performing three HVs for both the baseline and post-intervention trials. Furthermore, participants completed a countermovement jump test (CMJ) to assess the effect of PT on functional power. Through the use of Quintic biomechanics software, significant improvements (P < 0.05) were found for the PTG for run-up velocity, take-off velocity, hurdle to board distance, board contact time, table contact time and post-flight time and CMJ height. However, there were no significant improvements on pre-flight time, shoulder angle or hip angle on the vault for the PTG. The CG demonstrated no improvement for all HV measures. A sport-specific PT intervention improved handspring vault performance measures and functional power when added to the habitual training of youth female gymnasts. The additional two hours plyometric training seemingly improved the power generating capacity of movement-specific musculature, which consequently improved aspects of vaulting performance. Future research is required to examine the whether the improvements are as a consequence of the additional volume of sprinting and jumping activities, as a result of the specific PT method or a combination of these factors.
