“…Study in Turkey 2016 found that weight lifters (non-endurance sport) have greater body fat than swimming athletes (endurance sport). 26 Body fat percentage in swimming athletes is higher than other athletes in endurance sports (medium distance running, long-distance running, and rowing). These results were in line with research in Brazil 2017 which showed female swimming athletes has a higher body fat percentage than other athletes such as running, gymnastics, and rowing since these sports require more movement.…”

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.

“…However, adolescents with AN had lower LBMI Z ‐score than adolescents with AAN, and adolescents without a prior history of overweight had lower LBMI Z ‐score than adolescents with a prior history of overweight. Deficits in lean mass may contribute to low BMD (Koşar, ). Adolescents with AAN and a prior history of overweight did not demonstrate significant deficits in LBMI Z ‐score.…”

Objective: To compare bone mineral density (BMD) and body composition among adolescents: 1) with atypical anorexia nervosa (AAN) versus anorexia nervosa (AN) and 2) those with and without a prior history of overweight. Method: Electronic medical records of patients 9–20 years with AN or AAN who underwent dual-energy x-ray absorptiometry (DXA) scans were retrospectively reviewed and analyzed. Results: A total of 286 adolescents with AN or AAN were included. In linear regression models, AAN was associated with greater Z-scores in whole body bone mineral content (BMC, B=0.88, p<0.001), lumbar spine BMD (B=0.79, p=0.002), femoral neck BMD (B=0.670, p=0.009); fat mass index (FMI, B=1.33, p=0.003), and lean body mass index (LBMI, B=1.10, p<0.001) compared to AN, adjusting for age, sex, and duration of illness. A prior overweight history was associated with greater Z-scores in whole body BMC; lumbar spine BMD, total hip BMD, femoral neck BMD, and LBMI. Discussion: Adolescents with AAN had higher BMD Z-scores than adolescents with AN; adolescents with a prior overweight history had greater BMD Z-scores than adolescents without a prior overweight history. These findings may inform clinical guidelines for the medical management of AAN.

“…Compared to preceding studies that investigated adolescent female wrestlers [ 9 , 12 ], the present elite wrestlers demonstrated no outstanding features concerning the stature, the body mass, and the BMI ( Table 2 , stature: 151.9 ± 3.8 cm in LW and 161.9 ± 4.6 cm in HW, body mass: 47.2 ± 2.5 kg in LW and 61.6 ± 5.8 kg in HW, BMI: 20.5 ± 1.1 in LW and 23.5 ± 2.3 in HW). When compared with athletes other than wrestlers [ 14 , 26 , 27 , 28 , 29 ], the present wrestlers did not have particularly large BMI ( Table 2 ). Despite the importance of muscle development in wrestling, the present elite female wrestlers showed ordinary BMI, probably because competitive wrestling is conducted in a weight-class system.…”

Studies evaluating the physical fitness levels of elite wrestlers during junior high school are limited. This study aimed to examine the body composition and physical fitness profiles of elite Japanese female wrestlers aged <12 years until >20 years. There were 114 elite female wrestlers enrolled. Measurements were conducted in the following age categories: <12 years (U-12), <15 years (U-15), <17 years (U-17: cadet), <20 years (U-20: junior), and >20 years (senior). Body composition variables consisted of body mass index (BMI), percent body fat, fat free mass, and fat free mass index (FFMI). Fitness measurements included grip strength, back strength, sit-up, rope-climbing, and endurance running tests. The wrestlers in this study demonstrated comparable or greater FFMI values (e.g., FFMI: 17.9 ± 0.4 kg/m2 for light and 19.8 ± 0.9 kg/m2 for heavy weight categories in U-20), when compared with young female wrestlers in previous studies, whereas stature, body mass, and BMI of the wrestlers in our study were unremarkable. Regarding the fitness assessment, a remarkable increase in back strength was observed after late puberty. An outstanding enhancement of muscle strength after late puberty, which is unlikely to occur in ordinary women, would be an important requirement to become the world’s top female wrestler.
