A minority of female athletes participating in ballet, gymnastics, distance running, rowing, and cycling, as well as other sports activities, occasionally experience menstrual and associated physiologic changes. Women competing in the sports of ballet and gymnastics have been reported to have a particularly increased incidence of primary and secondary amenorrhea, decreased bone density, stress fractures, and symptoms of anorexia nervosa. Results of several studies have indicated decreased levels of circulating estrogen as well as other metabolic changes. Research designed to determine the etiology of the amenorrhea and the associated changes has shown mixed results. Low body fat cannot be linked in a causative fashion to hormonal changes or decreased levels of circulating estrogen. Early studies linking minimum body fat and menarche, as well as maintenance of regular menstrual cycles, have not been replicated. However, measurement of percentage of body fat may be helpful in assessing the nutritional status of athletes. Ballet and gymnastics are perceived by some to be activities that are stressful psychologically. Although stress has been shown to cause amenorrhea, studies to date have not demonstrated the presence of significantly increased levels compared with agematched girls not participating in ballet and gymnastics. Some authors have postulated that tall, thin athletes who may be genetically at risk for delayed maturation are naturally attracted to these sports. Some of the delays may relate to preselection. However, no evidence currently exists proving a definite relationship between preselection and the physiologic changes in these athletes. There is an increased emphasis by athletes, coaches, judges, and spectators on a slender physique for female gymnasts and ballet dancers.

Athletes’ nutrition status, somatotype, and adequate dietary intake are strongly related to their sport performance. Examining those markers in adolescent age is essential in order to develop the optimum physical characteristics for the future. This study was conducted to identify the nutrition status based on anthropometry value, somatotype, food and fluid intake of youth athletic athletes in Indonesia. Descriptive quantitative design was used in this study. Subjects participated in the study were 25 youth athletic athletes from Students Education and Training Program (Program Pembinaan dan Pelatihan Pelajar) in Yogyakarta and Aceh, and School of Sports (Sekolah Keolahragaan) Ragunan, Jakarta Selatan. Anthropometry measurement consists of body weight, height, body fat percentage, and somatotype. Nutrition status was identified according to BMI/age and height/age. Food and fluid intake were assessed using 24-hour dietary recall interview and semi quantitative fluid frequency questionnaire. Descriptive statistical analysis was performed and the result was presented in mean and deviation standard. BMI/age values in male and female athletes were -2 SD ≤ Z ≥ +1 SD (normal) and +1 SD ≤ Z ≥ +2 SD (overweight), respectively. Height/age value for both gender was normal in -2 SD ≤ Z ≥ +2 SD. Percentage of body fat ranged in 12-16% for males and 18-28% for females. Somatotype category for males was ectomorphic mesomorph (2.3-5.0-3.3) and endomorphic mesomorph (4.4-5.6-2.0) for females. Fulfillment of energy and carbohydrate was found inadequate (< 80%), whereas fat intake was found excess (> 110%). Total fluid intake was ranged from 2700 ml to 5800 ml per day. Overweight nutrition status was still found in female athletes. Ideal somatotype was found only in male athletes. Excessive percentage of body fat was detected in both gender. Total energy, macro nutrients, micro nutrients, and fluid intake were inadequate compared to dietary recommendation.

For the first time, body composition has been studied in a very large sample of female anorexia nervosa patients (n 200) using two methods: anthropometry (skinfold thickness) and densitometry (underwater weighing). The concurrent validity of both methods appeared to be good (r 0·84). Although the mean percentage of body fat (13·5) in our sample corresponds with most of the previous reports, the range (4·3–24·8) is great. Our study shows that BMI is not a good measure of fatness. Age and duration of illness were not related to body fat. Percentage fat was found to be different (t 2·76, P <0·01) according to the diagnostic subtype of anorexia nervosa: restricters (12·9) v. bingers and/or purgers (14·7).

Abstract Background An adequate hydration status is critical to ensure efficiency during mental and physical activities. Our goal was to assess the hydration status of a Spanish group of aeronautical military men and to determine the association of hydration status with body composition and anxiety. Methods A total of 188 men were evaluated through a validated hydration questionnaire, anthropometric and biochemical parameters, and an anxiety questionnaire. Based on these methods, the criteria of hydration were established. Results Of the total sample, 81% met the hydration criteria (urine color = well hydrated, water balance ≥ 0 ml, and total water intake/weight ≥ 35 ml/kg), and 19% did not meet the hydration criteria (urine color = not sufficiently hydrated or dehydrated, water balance < 0 ml, and total water intake/weight < 35 ml/kg). Subjects not meeting the hydration criteria had lower urine pH, negative water balance, and lower water intake. The latter also had higher anxiety status (score = 4 vs. 3, P = 0.026), weight [(84.7 ± 10.5) vs. (80.5 ± 10.2) kg], body mass index [(26.3 ± 3.1) vs. (25.2 ± 2.8)]kg/m2, body fat [(22.3 ± 5.6) vs. (18.3 ± 6.5)] %, urine specific gravity, and urine color. Using a logistic binary regression model, hydration status was related significantly with the percentage of body fat (P = 0.004), but no relation was found with age, comorbidities, or medications. Furthermore, total water intake/weight was positively correlated with percentage of body water (r = 0.357, P = 0.000) and negatively with body fat (kg) (r = − 0.427, P = 0.000), percentage of body fat (r = − 0.405, P = 0.000), and waist/hip ratio (r = − 0.223, P = 0.002). Based on a linear regression model, total water intake/weight was related significantly with percentage of body fat (P = 0.001) and percentage of body water content (P = 0.035). No relation was found, however, with waist/hip ratio, age, comorbidities, or medications. Conclusions These findings all suggest a relationship between hydration status and body composition but also set the bases for future studies that relate hydration status and anxiety status. These results can be used to improve the hydration status and body composition of military personnel.

Abstract Introduction and hypothesis Artistic gymnastics, team gymnastics and cheerleading are sports including high-impact activities. It is presumed that the athletes’ pelvic floor must be functioning well to prevent urinary (UI) and anal incontinence (AI) during sports. The aim of this study was to investigate the prevalence and risk factors for UI and AI in female artistic gymnasts, team gymnasts and cheerleaders; the influence of UI and AI on daily living and sport performance; and the athletes’ knowledge about the pelvic floor muscles (PFM). Methods All female athletes ≥ 12 years of age competing in ≥ 1 National Championship in artistic gymnastics, team gymnastics or cheerleading in 2018/2019 were invited. International Consensus on Incontinence Questionnaires were used to assess the prevalence/bother of UI and AI. Results Among the 319 gymnasts and cheerleaders who participated, the prevalence of UI and AI was 67% and 84%, respectively. Age, training ≥ 4 days/week and straining to void were significantly associated with stress urinary incontinence (SUI) and years of training with AI. Eighty-three percent of athletes with SUI reported a negative effect on sports performance, 22% would occasionally avoid training or specific exercises because of leakage, and 28% used pads for protection. Forty-one percent of the athletes had never heard about the PFM, and 74% reported an interest in PFM training to prevent/treat UI or AI. Conclusions UI and AI were prevalent in female gymnasts and cheerleaders, and SUI negatively influenced sport performance. The athletes’ knowledge about the PFM was limited.

Abstract Soccer is the most popular sport worldwide. Despite its global acclaim, scientific studies of soccer have tended to focus on tactics and techniques, thereby neglecting the physical and physiological profile of the players. Therefore, the purpose of this study was to examine physical and anthropometric characteristics of male South African university soccer players. Twenty-seven male soccer players aged 19 to 24 (mean age: 22.1 years; s = 1.5 years) volunteered to participate in the study. The results showed that goalkeepers (77.5 ± 9.7 kg) and defenders (68.2 ± 6.5 kg) were the heaviest compared to players in other playing positions. The goalkeepers also had the highest percentage of body fat (11.3 ± 2.3%), in contrast to midfielders who had the lowest body fat content (9.1 ± 0.9%). With regard to flexibility, defenders (45.1 ± 4.9 cm) and midfielders (45.9 ± 5.4 cm) performed better than goalkeepers (37.1 ± 4.3 cm) and strikers (40.1 ± 3.4 cm). Midfielders (57.2 ± 3.1 ml1·kg−1·min1) and defenders (56.1 ± 5.1 ml1·kg−1·min1) had significantly higher values of maximal oxygen uptake (VO2max) than goalkeepers (47.9 ± 0.2 ml−1·kg−1·min−1) and strikers (49.8 ± 6.2 ml−1·kg−1·min−1). No significant (p > 0.05) differences were observed for all other variables, with the exception of body height, body mass, and VO2max. It was therefore concluded that sports scientists and coaches should tailor conditioning programmes in soccer according to players’ positions in view of the implications for successful performance.
