Eating disorders are associated with short and long-term consequences that can affect sports performance. The purposes of this study were to investigate whether female athletes, particularly gymnasts and footballers, exhibit more eating problems compared to female non-athletes, and to identify individual personality characteristics including anxiety, self-esteem, and perfectionism as possible contributors to eating disorder risk. In a sample of 120 participants, 80 adolescent female athletes were compared to a control condition of 40 non-athletes (mean age 17.2 ± 2.82). Participants responded to a questionnaire package to investigate the presence of disordered eating (SCOFF) and psychological variables in relation to disordered eating symptoms or eating disorder status. Subsequently, anthropometric measures were obtained individually by trained staff. There were statistically significant differences between conditions. One of the most important results was the score in SCOFF (Mann–Whitney = 604, p < 0.05; Cohen’s d = 0.52, r = 0.25), being higher in control than in the gymnast condition. These results suggest that non-athlete female adolescents show more disturbed eating behaviours and thoughts than female adolescents from aesthetic sport modalities and, therefore, may have an enhanced risk of developing clinical eating disorders.

This study aims to investigate dietary composition and nutrition knowledge of 60 athlete and 59 non-athlete adolescent females (age, 14-18 years), using a 3-day food recall and a questionnaire on nutrition. The reported daily energy intake was similar in athletes and non-athletes, but less than the recommended and the estimated requirements. In the athletes, the energy supply from breakfast was higher than in the non-athletes (18.5 ± 6.6 vs. 15.0 ± 8.2%, p < .005). Energy intake from carbohydrates was higher (53.6 ± 6.2 vs. 49.8 ± 63%, p < .05) and that from lipids was lower (30.4 ± 5.5 vs. 34.2 ± 5.2%, p < .001) in athletes than in non-athletes. Athletes also showed higher fiber (20.0 ± 5.8 vs. 14.1 ± 4.3 g/day, p < .001). iron (10.6±5.1 vs. 7.5 ± 2.1 mg/day,/7 < .001) and vitamin A (804 ± 500 vs, 612 ± 456 μg/day, p < .05) reported intake than non-athletes. Calcium, iron, and zinc intake were less than 100% RDA in both groups. Athletes gave a slightly higher rate of correct answers on the nutrition knowledge questionnaire (77.6 vs. 71.6%,p < .01) than non-athletes. In conclusion, the overall recalled dietary intake and nutrition knowledge of the studied adolescent females show some misconceptions and nutrient deficiencies, but the results in athletes are quite better man in non-athletes, suggesting a favorable role of sport practice on dietary habits and nutrition knowledge.

Abstract The aim of this study was to determine whether young adolescent female artistic gymnasts demonstrate better functional stability than age- and sex-matched non-athletes. Different characteristics of the gymnasts’ postural control were expected to be observed. Twenty-two 10- to 13-year-old healthy females (ten national-level artistic gymnasts and twelve non-athletes) participated in the study. To assess their forward functional stability, the 30-s limit of stability test was performed on a force plate. The test consisted of three phases: quiet standing, transition to maximal forward leaning, and standing in the maximal forward leaning position. Between-group comparisons of the directional subcomponents of the root mean squares and mean velocities of the center of pressure and rambling-trembling displacements in two phases (quiet standing and standing in maximal leaning) were conducted. Moreover, anterior stability limits were compared. During standing in maximal forward leaning, there were no differences in the center of pressure and rambling measures between gymnasts and non-athletes (p > 0.05). The values of trembling measures in both anterior-posterior and medial-lateral directions were significantly lower in gymnasts (p < 0.05). Both groups presented similar values for anterior stability limits (p > 0.05). The comparisons of rambling components may suggest a similar supraspinal control of standing in the maximal leaning position between gymnasts and healthy non-athletes. However, decreased trembling in gymnasts may indicate reduced noise in their postural control system possibly due to superior control processes at the spinal level. The anterior stability limit was not influenced by gymnastics training in female adolescents.

Background: Adolescent dancers may be a high-risk population for patellofemoral instability (PFI), but the condition remains under-investigated, to date, in this sub-group of athletes. Purpose: The purpose of this study was to (1) investigate the descriptive epidemiology of PFI in adolescent dancers, (2) analyze the efficacy of various patellar stabilization procedures within this population, and (3) compare PFI in dancers to a larger control group of matched, non-dancer athletes. Methods: A retrospective review of athletes, ages 10 to 19, who presented to a single tertiary care center with PFI between 2008 and 2017 was performed. Based on each patient’s primary sport, the cohort was divided into a dancer and a non-dancer control group. Demographics, clinical and radiologic features, surgical stabilization technique, and postoperative course and clinical outcomes were collected. Independent categorical groups were tested using chi squared and Fisher exact tests. Results: 258 adolescent athletes were included, 41 of whom were dancers, all females. This group was therefore matched with a control group of similarly aged, all-female athletes with PFI (Table 1). 54 athletes had bilateral PFI, yielding 285 knees for analysis. There was no difference between dancer and non-dancer athletes’ age, BMI, laterality, mechanism of injury, nor number of preoperative instability events. However, dancers had lower Dejour Classifications (p=0.044), smaller patella inclination angles (20.9±8.14 versus 25.0±9.84; p=0.004), and smaller Caton-Deschamps Indices (1.18±0.161 versus 1.25±0.189; p=0.041). Among dancers, there was no association between surgical stabilization technique and rates of recurrent instability (p=0.418) nor re-stabilization procedures (p=1.0) (Table 2). However, dancers who underwent tibial tubercle osteotomy (TTO) had higher rates of subsequent, non-stabilization procedures (66.7%), all for implant removal, compared to those undergoing isolated medial retinacular repairs (MRP) (3.8%) (p<0.001). There was no difference between the dancer and non-dancer athletes’ rates of recurrent instability (p=0.297), re-stabilization procedures (p=0.061), nor subsequent non-stabilization procedures (p=0.242). Conclusions: Female dancers with PFI have similar demographic and clinical features as other female athletes with PFI, but have lower rates or less severe trochlear dysplasia, lateral tilt and patella alta. Therefore, the ligamentous laxity inherent in dancers may be a more powerful risk factor for PFI than other non-modifiable risk factors. Notably, the TTO was a powerful stabilization procedure for this sub-population with low rates of recurrent instability episodes and no revision stabilization procedures performed. Rates of implant removal surgery following TTO may be substantial, though this may be technique or surgeon dependent. Tables/Figures: [Table: see text][Table: see text]

The aim of this paper is to examine the differences in particular dimensions of selfconcept in female and male adolescents depending on sports engagement, as well as to determine which domain-specific self-perceptions provide the highest contributions to global self-worth in female and male adolescents engaged in sport and those not engaged in it. This research included 400 subjects at early adolescent age, of both genders (235 females and 164 males) further divided to sub-samples of athletes and non-athletes. An adapted version of a scale Self-Perception Profile for Adolescents (Harter, 1988) was applied, which consists of nine subscales. The obtained results indicate that sport-engaged adolescents of both genders provide more favourable perception of themselves in most tested aspects of self-concept than those not engaged in an organized sports activity. Engagement in sport has special effect on selfconcept of male adolescents. Results of multiple regression analysis point out unambiguously the significance of self-perception of physical appearance in global self-worth of adolescents of both genders, irrespective of whether they are involved in sports activity or not.

El presente estudio evaluó la percepción sobre su imagen corporal actual, ideal, social e inconformidad corporal entre adolescentes mexicanas deportistas vs no-deportistas. La muestra fue obtenida por conveniencia con un total de 408 mujeres con una edad de M= 14.24 y DE= 1.69 años; 198 de ellas conforman el grupo de deportistas (M=14.30 y DE= 1.57) ya que practican algún deporte y participan regularmente en torneos o competencias deportivas, las otras 210 participantes son del grupo de no deportistas (M= 14.18 y DE= 1.79). Todas contestaron la Escala Informatizada para la Estimación del Contorno de la Figura (EIECF) adaptada e informatizada. Los resultados del análisis de la varianza, muestran que las adolescentes no deportistas son quienes eligen modelos más gruesos para su figura actual y social, además de mostrar mayor inconformidad corporal. Resultados que permiten concluir que, en general, las personas activas tienen una mejor percepción de su imagen corporal, que las sedentarias.Abstract. This study consisted in determining differences and similarities between Mexican adolescents who practice a sport and those who do not with regard to their perception of their actual, ideal, and social body image, as well as their body dissatisfaction. A total sample of 408 female teenagers aged 12-17 years old participated in this study; 198 of them practiced a sport and regularly participated in tournaments or competitions. All the participants completed the Contour Drawing Rating Scale adapted and computerized by Gastélum and Blanco (2006). The results of the one-way multivariate analysis of variance, followed by the one-way univariate analyses of variance, showed that adolescents who do not regularly participate in sports show thicker models in their present and social body image, in addition to displaying higher body dissatisfaction.

Background This study aimed to clarify the relationship between the triad risk assessment score and the sports injury rate in 116 female college athletes (average age, 19.8 ± 1.3 years) in seven sports at the national level of competition; 67 were teenagers, and 49 were in their 20s. Methods Those with menstrual deficiency for >3 months or <6 menses in 12 months were classified as amenorrheic athletes. Low energy availability was defined as adolescent athletes having a body weight <85% of ideal body weight, and for adult athletes in their 20s, a body mass index ≤17.5 kg/m2. Bone mineral density (BMD) was measured on the heel of the right leg using an ultrasonic bone densitometer. Low BMD was defined as a BMD Z-score <−1.0. The total score for each athlete was calculated. The cumulative risk assessment was defined as follows: low risk (a total score of 0–1), moderate risk (2–5), and high risk (6). The injury survey recorded injuries referring to the injury survey items used by the International Olympic Committee. Results In swimming, significantly more athletes were in the low-risk category than in the moderate and high-risk categories (p = 0.004). In long-distance athletics, significantly more athletes were in the moderate-risk category than in the low and high-risk categories (p = 0.004). In the moderate and high-risk categories, significantly more athletes were in the injury group, whereas significantly more athletes in the low-risk category were in the non-injury group (p = 0.01). Significantly more athletes at moderate and high-risk categories had bone stress fractures and bursitis than athletes at low risk (p = 0.023). Discussion These results suggest that athletes with relative energy deficiency may have an increased injury risk.

Background: Based on the duration and intensity of the exercise, sports can b classified into two types: endurance and non endurance (strength and power). Endurance sports is a high risk sport with low diet quality, nutritional status (body mass index (BMI) and body fat percentage), and haemoglobin level. Objectives: The aimed of this study is to analyze the differences of diet quality, nutritionl status, and haemoglobin level of female adolescent athletes in endurance and non endurance sports. Methods: An observational study with a cross-sectional design was conducted on 23 endurance athletes and 21 non endurance athletes in BBLOP Central Java, UNNES swimming and athletic sports club, and Salatiga atlhetic sports club. Subjects were selected by purposive sampling. BMI and body was measured by Bioelectrical Impedance Analysis (Tanita DC-360). Haemoglobin level was assessed by cyanmethemoglobin method. Diet quality was measured by semi quantitative food frequency questionnaire (SQ-FFQ) and diet quality index-international (DQI-I) form. Data was analyzed by independent t-test and Mann-Whitney. Results: The majority of nutritional status based on BMI and perventage body fat in endurance and non endurance athlete were normal. About 9,5% of non endurance athlete had anemia. There were significant difference in diet quality (p=0,029) and variety of protein source, iron, vitamin C, and empty calorie foods intake (p<0,001; p=0,028; p=0,045; p<0,001) of endurance and non endurance athletes, but no significant difference in body fat percentage (p=0,573) and haemoglobin level (p=0,714). Conclusion: There were significant difference on diet quality, variety of protein source, iron, vitamin C, and empty calorie foods intake between endurance and non endurance athletes.

Research has shown that elite female athletes competing in competitive sports may experience weight consciousness and face demands to conform to unrealistic standards of body weight. The purpose of this research was to investigate body image and dieting behaviours in adolescent female athletes and non-athletes. A self-reporting questionnaire was administered to 60 athletes aged between 13-16 years derived from eight different sporting populations, and a control group consisting of 60 non-athletes or inactive individuals aged between 13-16 years. Two major areas relating to weight and eating behaviours were examined: disordered eating and distorted body image. Other variables under investigation included current attempts at weight loss, level of acceptance of thin female stereotypes promoted by the media, reasons for dieting, and perception of one’s own body image. Results indicated that the majority of the athletes displayed a positive body image and were generally happy with their overall body shape. This group was less likely to employ weight loss behaviours. However, the non-athletes were more likely to display distorted body image and distorted eating behaviours. Consistent with the cultural expectations of thinness, large proportions of the non-athletes wished to lose weight, even though their actual weight (i.e. Body Mass Index) was normal or underweight. Weight concerns in the non-athlete group related more to attaining a media driven “ideal” of femininity. The weight concerns recorded amongst a small number of athletes were related more to improving sporting performance. Although no clinically diagnosed cases of eating disorders were recorded, eating behaviours, weight reduction practices and body image beliefs indicated that the adolescent female non-athletes may be at risk of developing disordered eating and body image problems.

Competitive swimming is a sport in which "the need to succeed" is stressed and the desire to reach the optimal level of performance--physically, emotionally, and nutritionally is strong. This research sought to investigate whether there were differences in nutrient intakes, percent body fat, and body image between male and female swimmers and their non-athletic counterparts at Muncie Central High School in Muncie, Indiana.The accessible population for this study included those male and female athletes and non-athletes, ages 14 to 18, who attended Muncie Central High School during the 1989-1990 school year.The data indicated that athletes did not differ from non-athletes while males and females did differ significantly in significant differences in height between athletes and non-athletes, primarily due to the differences in the height of female athletes as males appeared to be similar, but female athletes were one-half inch taller, on the average, than female non-athletes. There were no significant differences between the weights of male between athletes and non-athletes,male non-athletes were and female athletes and non-athletes; however, male athletes were 13 lbs. lighter, on the average, than their male counterparts. There was a significant interaction, in percent body fat, significantly fatter than male athletes. There was a tendency for males to have lower scores on the Eating Attitudes Test (EAT) than females, suggesting that males were at lower risks for disorders than females.These data suggest that nutrition education programs should be planned to ensure good diets for all students, athletes, and non-athletes.Department of Home Economics
