Study Results

The first aim of this study was to compare body mass index (BMI) (indirect method) classification with the body fat percent (PBF) (direct method) and to determine how BMI classifies subjects with different levels of skeletal muscle mass percent (PSMM). The second aim was to determine the prevalence of overweight and obesity status among police trainees (PTs). A total of 103 male PTs participated in this research: age = 21.46 ± 0.64 years, body mass (BM) = 75.97 ± 8.10 kg, body height (BH) = 174.07 ± 6.31 cm, BMI = 25.05 ± 2.12 kg/m2. The InBody 370 multichannel bioelectrical impedance analysis (BIA) measured body composition. Study results indicated that muscular PTs could be misclassified as overweight and that PBF identified more subjects as obese. Namely, three PTs were obese according to BMI, while 13 were obese according to PBF. The information provided by this research could be used to help professionals understand the importance of measuring body composition, and the inaccuracies in BMI classification. In conclusion, whenever possible PSMM and PBF should replace the utilization of BMI to screen overweight and obesity in PTs. Agencies may think of using BIA as non-invasive, quick and inexpensive measurement tool.

Body Scan

Overweight and obesity are considered among the major health concerns worldwide. The body mass index is a frequently used measure for overweight and obesity and is associated with common non-communicable diseases such as diabetes type II, cardiovascular diseases and certain cancers. However, the body mass index does not account for the distribution of body fat and relative fat to muscle mass. 3D laser-based photonic full body scans provide detailed information on various body circumferences, surfaces, and volumes as well as body height and weight (using an integrated scale). In the literature, body scans showed good feasibility, reliability, and validity, while also demonstrating a good correlation with health parameters linked to the metabolic syndrome. However, systematic differences between body scan derived measurements and manual measurements remain an issue. This study aimed to assess these systematic differences for body height, waist circumference, and body mass index using cross-sectional data from a homogenous sample of 52 young Swiss male volunteers. In addition to 3D laser-based photonic full body scans and correlative manual measurements, body fat distribution was assessed through bioelectrical impedance analysis. Overall, an excellent correlation was found between measurements of waist circumference and body mass index, and good correlation between body mass index and total fat mass, as well as between waist circumference and visceral fat mass as assessed by bioelectrical impedance analysis. Volunteers were shorter in height measured by body scan when compared to manual measurements. This systematic difference became smaller when volunteers stood in the scanner in a completely upright position with their feet together. Waist circumference was slightly smaller for manual measurements than for body scan derived values. This systematic difference was larger in overweight volunteers compared to leaner volunteers.

Introduction. Anthropometric measurements are widely used in the assessment of growth, nutritional status and body composition in children. The objective of the study was to describe growth and body composition of children using simple anthropometric measures. Material and Methods. The investigation was performed in 13 primary schools in the territory of North Backa during 2017 and at the beginning of 2018. A total of 593 schoolchildren aged 6.50 - 10.49 years (in decimals) were included in the study. The following parameters were measured: height, weight, upper arm circumference and triceps skinfold thickness. These measurements were used to calculate the body mass index, total upper arm area, upper-arm muscle area, upper-arm fat area, and the arm fat mass percentage for each individual. Results. The study results show that children?s growth is almost linear over the first decade of life and the lean body mass increases at similar rates in boys and girls. However, girls show higher percentage of body fat and higher triceps skinfold thickness, while the body mass index is not significantly different. The secular trends in height are slowing down or have already ceased, but the weight generally continues increasing. Conclusion. Although sexual differences in anthropological measures are insignificant, the differences in body composition are evident before puberty.

Introduction. Body composition measurements and dynamometric parameters are very reliable indicators of performance and progress in the training process. The aim of this study was to assess the body composition and muscle strength and to establish the correlation between these parameters in various sports. Material and Methods. The study was conducted at the Department of Physiology, Laboratory of Functional Diagnostics, Faculty of Medicine in Novi Sad. It included 45 male examiners: 15 handball players, 15 football players, and 15 sprinters. The following parameters were measured: body weight, body height, body mass index, skinfold thickness, and dynamometric parameters of calf extensors and forearm flexors. Results. In comparison to football players and sprinters, handball players presented with statistically significantly higher body mass index (p < 0.05). In terms of skinfold thickness, there were statistically significant differences (p < 0.05) between the groups. The values of dynamometric parameters of calf extensors (average value of load of the calf extensors, maximum value of load of the calf extensors, strength of muscle contraction of calf extensors) showed no statistically significant differences between the groups of athletes (p > 0.05). Compared to football and handball players, sprinters had significantly higher values of dynamometric parameters of forearm flexors (average value of load of forearm flexors, maximum value of load of forearm flexors, strength of muscle contraction of forearm flexors). Conclusion. In the group of handball players there was a positive correlation between the percentage of the body fat and muscle power in both examined muscle groups; however, among the football players and sprinters, a correlation was found between the body composition and strength of calf extensors.

The Relationship

INTRODUCTION: Physical activity is an essential element in our daily life that leads to long-term health benefits. Physical activity refers to movement of the body that requires energy. Body mass index (BMI) indicates a ratio of body weight to squared height, which is a useful health indicator. On the contrary, body composition describes the body by measuring percentages of fat and muscle in human bodies. MATERIALS AND METHODS: This cross-sectional study aimed to determine the relationship between physical activities, BMI and body composition among pre-university students from one of the universities in Selangor, Malaysia. Stratified random sampling was employed to recruit 70 pre-university students into this study. RESULTS: From the study, 50% of the respondents are categorized as minimally active. In addition, there is significant difference between the physical activity levels of male and female respondents. The relationship between physical activity and BMI indicates a very weak negative correlation. Similarly, the correlation between physical activity and fat mass is a weak negative relationship. Meanwhile, there is a weak positive correlation between physical activity and muscle mass. CONCLUSION: Therefore, it can be concluded that when physical activity increases, BMI and body fat mass will decrease, while muscle mass will increase. Moreover, it was shown that there was a significant relationship between physical activity and body composition.

The Body composition is related to higher physical performance and a lower risk of health problems, it connects to external and internal factors. Military activitiesf are characterized with a high physical load and a psychological load, physical fitness and the body composition have an adverse effect on military performance. The primary purpose of the body composition and physical fitness is related to the selection of individuals the best suited to the demands of military service [2,10]. The proper body mass supports good health capacity [11,13]. The maintenance of body composition and appropriate physical fitness standards by the military personnel is affected by the intrinsic factors such as the individual’s genetic factors, development history, social background, and extrinsic factors, environmental changes and institutional, systemic changes. The effects of the excess body mass are widespread, raise the variety of concerns relevant to the health and performance of the military personnel [1,3,4,5]. The diabetes mellitus, hyperlipidemia, hypertension and heart disease increased with the obesity [6,7,9,12]. The individuals with overweight have more medical complication than the individuals with the standard body mass. The higher body mass index was associated with higher morbidity and mortality [8]. We have classified individuals according to the age into subgroups and provided the evaluation of the body composition on the basis of the main anthropometric characteristics as well the analysis of the standard physical fitness tests results. The analysis of the average value of the body mass and the Body Mass Index have shown large individual changes inside the subgroups and between the subgroups. The assessment of the results of physical fitness tests is provided differentially according to the individual corresponding age subgroup. The analysis of the respondent data reveals the overweight and obesity problem that became actual with the increasing the age of individuals. Physical fitness tests results have shown that the excellent physical fitness evaluation is received by about 33–44% of the military personnel that reflects a high unit of operational readiness.

Objectives: To retrospectively investigate the reliability of the age-based formula, year/4 + 3.5 mm in predicting size and year/2 + 12 cm in predicting insertion depth of preformed endotracheal tubes in children and correlate these data with the body mass index. Patients and Methods: Patients were classified into 4 groups according to their nutritional status: thinness, normal weight, overweight, and obesity; we then retrospectively compared the actual size of endotracheal tube and insertion depth to the predicting age-based formula and to the respective bend-to-tip distance of the used preformed tubes. Results: Altogether, 300 patients were included. The actual endotracheal tube size corresponded with the Motoyama formula (64.7%, 90% CI: 60.0-69.1), except for thin patients, where the calculated size was too large (0.5 mm). The insertion depth could be predicted within the range of the bend-to-tip distance and age-based formula in 85.0% (90% CI: 81.3-88.0) of patients. Conclusion: Prediction of the size of cuffed preformed endotracheal tubes using the formula of Motoyama was accurate in most patients, except in thin patients (body mass index < −2 SD). The insertion depth of the tubes was mostly in the range of the age-based-formula to the bend-to-tip distance.

The aim of the present study was to analyse body composition, anxiety, cardiovascular, and physical activity factors related with academic performance of school students as well as to analyse differences, by age, in these factors. We analysed in 266 primary school students’ (8.81 ± 1.62 years, range: 5–13 years) heart rate, anthropometric variables to calculate body mass index, physical activity performance, anxiety levels and academic results by the average of marks. Students were divided in two different groups, firstly by their lower or higher academic performance, and secondly by age. Results showed a negative correlation between academic performance and age, weight, body mass index and trait anxiety variables. Additionally, significant differences were found by age, presenting older students higher scores in body mass index and lower physical activity, trait anxiety, heart rate and academic performance values than younger students. Overweight and obesity may have a great impact in academic performance in children and we pointed out the necessity to establish programs related with healthy habits which include improvements in physical activity and nutrition behaviours with the objective to enhance children’s health general status, psychological profile, cognitive and motor development, and academic performance.
