A large body size and mass are advantages in rugby. The desire to gain weight can bring players to become overweight or obese. This can worsen their thermoregulation and health risks. The aim was to evaluate anthropometric characteristics and to determine the effect of additional body fat percentage on sweat loss during play-match in male rugby players. Nineteen qualified male rugby players were tested during play-match. The age, height, body mass, body mass index (BMI) and body fat percent of participants were: 29 ± 6 years, 183 ± 7 cm, 96.86 ± 12.88 kg, 29.07 ± 3.90 kg/m2, 20.52 ± 5.64%, respectively. The skin fold thickness measurement was used to assess body fat percent. Body mass loss was detected by weighting. The mean BMI was 26.18 ± 2.37 (kg/m2) and the body fat 15.87 ± 3.97% in backs. Forwards were significantly heavier and had BMI 31.18 ± 3.44 (kg/m2)(p = 0.002) and the body fat 23.91 ± 4.02% (p < 0.001). The mean body mass decrease in the play-match was 1.83 ± 0.84%. The mean sweating intensity was 2.24 ± 1.07 l/h, but individual varied among players in very wide range (1.12–6.16 l/h). Relationships between the body fat percentage and sweating intensity was not determined (p > 0.05). Recommendation is to increase the volume of regular strength training, to correct the diet and liquid consumption.

Body mass index (BMI) is to monitor nutritional status adults, especially those related to deficiency and overweight. Body fat percentage can describe the risk of degenerative diseases.This study was conducted to measure the relationship between BMI and body fat percentage. Methods An analytical study was conducted to 41 male and 51 female participant from Universitas Teuku Umar. The body weight was measured using scales, whereas the body height was measured using microtoise. The body fat percentage was measured using Karada Scan. The BMI was calculated by dividing the body weight in kilogram divided by body height in meter square. Data was collected from 16-18th February 2021 and analyzed by Pearson’s correlation test. The results showed BMI underweight, normal, and overweight were 10,9, 57,6, and 31,5. High body fat percentage in men were 75,6% and in women were 35,5%. There is a relationship between the nutritional status of the women group and the body fat percentage with p-value is obtained = 0.021. Furthermore, for men, there is no relationship between nutritional status in the men group and the body fat percentage. There is a relationship between nutritional status and body fat percentage in women. Among this population, BMI can still be used to determine body fat percentage

Background: One of the conditions on premenopausal period is the increase in body fat, among which are caused by levels of the fluctuating estrogen hormone. Increase fat affects the body fat percentage and adipsin levels. Adipsin plays a role in the stimulation of insulin secretion by producing C3a, in which C3AR1 (C3a Receptor 1) fragments interact with beta cells to secrete insulin.Objective: The purpose of this study is to determine correlation of body fat percentage with adipsin levels on premenopause.Design: This was an analytical study with cross-sectional design. Body fat percentage was obtained by examination using Bioelectrical Impedance Analysis (BIA). Venous blood was taken at the mediana cubiti area used for serum adipsin levels. Adipsin levels were analyzed by Enzyme-linked Immunosorbent Assay (ELISA) technique.Results: The mean of body fat percentage on premenopausal was 36,18 ± 8,35%. The mean of adipsin levels on premenopausal was 117,05 ± 87,93 ng/ml. Result of Pearson test analysis got value r = 0,632 and value p = 0.0005 (p <0,05).Conclusions: There is a positive significant correlation between the percentage of body fat with adipsin levels on premenopause.

The study was aimed to evaluate cardiovascular risk parameters, body mass index (BMI) centiles for sex and age, and body fat percentage using the electric bioimpedance method in children with juvenile idiopathic arthritis (JIA). 30 children with JIA participated in the study. A control group included 20 children. Patients were well matched for the age and sex. The body mass and body fat percentage were determined using the segmental body composition analyser; the BMI centiles were determined. All patients had the following parameters determined: lipid profile, hsCRP, homocysteine, and IL-6. The intima media thickness (IMT) was measured. Patients with JIA had significantly lower body weight, BMI, and the BMI centile compared to the control group. The IL-6 levels were significantly higher in patients with JIA compared to the control group. There were no differences between two groups with regard to the lipid profile, % content of the fat tissue, homocysteine levels, hsCRP, and IMT. Further studies are necessary to search for reasons for lower BMI and BMI centile in children with JIA and to attempt to answer the question of whether lower BMI increases the cardiovascular risk in these patients, similarly as in patients with rheumatoid arthritis (RA).

The aim of the study is to improve talent search, training methodology and injury prevention in women’s soccer. It analyses to what extent there are physical differences between top female soccer players (S) and a control group of sporty females (ff = fitness females). Furthermore, it examines whether differences in injuries can be identified between individual game positions (defense, midfield, forward, goalkeeper) and/or somatotypes. For this purpose, the anthropometric measurements of 233 top female soccer players (Ø 22 years old) and 40 fitness females (Ø 25 years old) who had been doing regular strength/endurance training twice a week for 2 years were statistically recorded, evaluated and used for determination of constitutional types according to Heath and Carter, Conrad and Knussmann and the AKS index according to Tittel and Wutscherk. In addition, body fat percentage according to Siri and the body mass index (BMI) were calculated. For the sample of soccer players, the types of injuries (categories: cruciate ligament, other knee, ankle joint/foot, shoulder/torso/hip, other injuries) and injury frequency according to the game positions, somatotypes and various body mass indices were compared statistically. There were significant differences between the anthropometric measurements of pelvic circumference (S: 81.2 ± 4.3cm; ff: 95.7 ± 7.7 cm; p ≤ 0.001) and maximum femoral circumference (S: 54.1 ± 3.1 cm; ff: 51.1 ± 4.4 cm; p ≤ 0.001). In terms of kinanthropometry, there were significant differences in the somatochart according to Heath and Carter [9] (S: 4/5/2; ff: 6/5/3), in the checkerboard pattern according to Conrad [3] (S: leptomorphic/hyperplastic; ff: metromorphic/hyperplastic) and in body fat percentage (S: 18.1 ± 2.1%; F: 25.0 ± 4.3%; p ≤ 0.001). The goalkeepers differed significantly from the field players with higher heights, lengths, sizes, higher body weight and a higher proportion of other injuries (e.g. hand, arm and head injuries). In constitutional terms, they differed only slightly from the field players. These appeared homogeneous in terms of body structure and injury mechanisms.

Abstract This papers aims at identifying the mean body mass index and body fat percentage among students from Physical Education and Sport Faculty in Iaşi. The study was conducted on a series of 297 students majoring in Physical Education and Sports, but also in Kinetotherapy and Special Motricity (bachelor studies and master studies). By determining the body mass index mean and body fat mean for students within five specialties, we managed to classify them into categories. The assessment of body mass index was conducted using the standard formula BMI= weight in kilograms/height in meters2 and that of body fat using the Fat Track II body fat calliper. Research findings highlighted that the body mass index mean values for each academic year range within normal parameters. As for body fat, the mean value of all academic years ranges in the “very good” and “good” categories. Whereas most mean values range within normal limits, it must not be neglected that overweight or underweight cases were also pinpointed, which should be a warning sign for the future specialists in the field of Physical Education and Sports.

Objective: To compare the anthropometric characteristics of sedentary women beginners in a physical exercise program in the gym, which had clinical diagnosis of hypothyroidism, with women who did not have hypothyroidism. Methods: The sample consisted of eighty women aged between 23 and 45 years who started in a gym at an interval of two years and who had hypothyroidism and the control group, without this pathology, selected in a simple random way. Anthropometric measurements, such as body mass, height, body mass index, abdominal circumference and waist, and body fat percentage were performed. Student's t-test was applied for independent samples between groups and Pearson correlation within groups. The statistical significance adopted was p < 0.05. Results: The group with hypothyroidism showed significant difference (p = 0.05) compared to control group for the body fat percentage just for women above 35 years, just like women with hypothyroidism above 35 years showed strong association of anthropometric variables with waist hip ratio (r ≥ 0.70). Conclusion: Sedentary women, above 35 years and affected by hypothyroidism, showed greater association of anthropometric variables with the predisposition to the risk of developing cardiovascular disease compared to their peers without the condition, and below this age range.
