ObjectivesThis paper aimed to report the prevalence of drop-out from organised sports between the ages of 10 and 14 years, and to examine potential associated detriments to levels of body fat.MethodsAll data were drawn from waves 4–6 of the Longitudinal Study of Australian Children. Participants’ sport participation was parent reported and body fat percentage was measured using bioelectrical impedance analysis. A total of 4159 participants had sports participation data at age 10 years (M=10.32 years, SD=4.68).ResultsFrom 3013 sport participants at age 10 years, 29.7% (n=894) had dropped out of sports at age 12 years. Of 2016 sport participants at age 12 years, 33.3% (n=705) had dropped out of sports by the age of 14 years. There were no differences in body fat percentage at any age according to differences in sport participation behaviours.ConclusionsBased on a high prevalence, drop-out from organised extracurricular sports during childhood and adolescence may be an important public health behaviour to consider. A solution-oriented approach to dropout from organised sports is recommended, but more evidence as to potential health detriments is needed using high-quality research designs.

The aim of the presented study was to assess changes in body composition and intersexual differences among children at pre-pubertal and early-pubertal age. The research was designed as a non-randomized cross-section study. The screened sample consisted of 136 girls and 212 boys assigned into three groups according to their age. Body composition was measured using a direct segmental multi-frequency bioelectrical impedance analysis (DSM-BIA). To examine the association between obesity and selected health-related parameters, Kruskal-Wallis ANOVA and Eta2 were used. For evaluation of intersexual differences, Mann-Whitney U-test was used. The presented article is the part of VEGA 1/0840/17 project. From the perspective of age, neither in the group of girls nor boys we recorded any differences in indicators of body composition, namely in body fat mass index, body fat percentage and, in addition, in the group of girls in the waist to hip ratio parameter.

Abstract: Physical activity is a body movement produced by skeletal muscles which requires energy. Lack of physical activity has a negative impact, one of which is an increase in body fat percentage above the normal threshold or often associated with obesity. Zumba is one of the popular aerobic exercises in the form of dancing. This study was aimed to compare the percentage of body fat before and after undertaking Zumba exercise in adult woman. This was an experimental field study with the one group pretest-posttest design. Samples were obtained by using total sampling technique. Zumba exercise was undertaken for 4 weeks, 3 times a week for 60 minutes. The percentage of body fat was measured by using an instrument based on Bioelectrical Impedance Analysis. Data were analyzed with the Wilcoxon Signed Rank test. The results showed that l6 subjects were involved in this study. The mean percentage of body fat percentage before Zumba exercise was 39.300% (SD±8.1041) meanwhile the mean percentage of body fat percentage after Zumba exercise was 39.031% (SD±7.9232). The statistical analysis to compare the body fat percentage before and after doing Zumba exercise obtained a P value of 0.065. Conclusion: There was no significant difference in body fat percentage before and after undertaking 4-week Zumba exercise among adult females.Keywords: body fat percentage, Zumba exercise Abstrak: Aktivitas fisik merupakan gerakan tubuh yang dihasilkan otot rangka yang memer-lukan energi.

Abstract The purpose of this study was to determine the relationship between peak cadence indicators and body mass index (BMI) and body fat percentage (BF%)-defined weight status in children. The sample comprised 485 Brazilian children. Minute-by-minute step data from accelerometry were rank ordered for each day to identify the peak 1-minute, 30-minute and 60-minute cadence values. Data were described by BMI–defined and bioelectrical impedance-determined BF% weight status. BMI-defined normal weight children had higher peak 1-minute (115.5 versus 110.6 and 106.6 steps/min), 30-minute (81.0 versus 77.5 and 74.0 steps/min) and 60-minute cadence (67.1 versus 63.4 and 60.7 steps/min) than overweight and obese children (p<.0001), respectively. Defined using %BF, normal weight children had higher peak 1-minute (114.5 versus 106.1 steps/min), 30-minute (80.4 versus 73.1 steps/min) and 60-minute cadence (66.5 versus 59.9 steps/min) than obese children (p<.0001). Similar relationships were observed in boys; however, only peak 1- minute cadence differed significantly across BMI and %BF-defined weight status categories in girls. Peak cadence indicators were negatively associated with BMI and BF% in these schoolchildren and significantly higher among normal weight compared to overweight or obese children.

In some countries, obesity rates among police officers are higher than the general public, despite physically demanding jobs. Obesity rates based on body mass index (BMI) may lack accuracy as BMI does not directly address body composition. Since data are lacking for obesity rates among Russian police officers, this study documented and compared officer obesity rates to the adult Russian population and compared the accuracy of body mass index (BMI) for obesity classification to two direct measures of body composition. Moscow region police officers (N = 182, 84% men) underwent height, weight, waist circumference (WC), and body fat percentage (BF%) bioelectrical impedance measurements during annual medical examinations. BMI-defined obesity rates were 4.6% for men and 17.2% for women, which were >3 and >1.8 times lower than Russian adults, respectively. WC-defined obesity rates were similar to BMI (3.3% for men and 10.3% for women), but BF%-defined obesity rates were much higher (22.2% for men and 55.2% for women). Although obesity rates were lower than those found among police officers in other countries, BMI alone was not a particularly accurate method for classifying weight status among Russian police officers.

The objective of the present study was to compare different methods for evaluating body fat percentage (BF%) (anthropometric methods and bioelectrical impedance analysis) in university students. Subjects were 653 healthy students whose mean age, body height, body weight and BMI were 21·1 (SD 2·5) years, 166·0 (SD 8·4) cm, 62·8 (SD 11·0) kg and 22·7 (SD 3·1) kg/m2, respectively. Results showed that BMI is a poor predictor of body fatness since the sensitivity was low in comparison with the reference method (Siri equation). The lowest values of BF% were obtained using the reference method (Siri equation) (21·8 (SD 6·8)%). The two methods with the highest agreement were Siri and Lean (mean difference, −0·5), followed by Brozek (mean difference, −1·4) and Deurenberg (mean difference, −1·5). The largest mean difference for BF% was between Siri and impedance (−4·5). Although the methods and/or equations used in the present study have been commonly utilised to estimate BF% in young adults, the results must be interpreted with caution in the diagnosis and monitoring of overweight and obesity.

Objective.To compare the measurements of body fat percentage (BF%) using the foot-to-foot bioelectrical impedance analysis (FTF-BIA) with the direct segmental multifrequency BIA (DSM-BIA).Methods.There were 36 men and 52 women (37.1±14.3years) with 57% Malays, 30% Chinese, and 13% Indian. For children, there were 45 boys and 26 girls (11.5±2.5years) with 52% Malay, 15% Chinese, and 33% Indian.Results.Mean height for men was 168.4 cm, 11 cm taller than women. Men were 10 kg heavier than women at 70 kg. BF% in women was 32% and 33% whereas BF% in men was 23% and 25% when measured using FTF-BIA and DSM-BIA, respectively. In children, BF% measured with FTF-BIA and DSM-BIA was 49% and 46%, respectively. The correlations were significant for men (r=0.92, SEE = 2.80), women (r=0.91, SEE = 3.31), boys (r=0.95, SEE = 5.44), and girls (r=0.96, SEE = 5.27). The BF% in underweight/normal (r=0.92, SEE = 2.47) and that in overweight/obese adults (r=0.89, SEE = 3.61) were strongly correlated. The correlations were significant in normal/underweight (r=0.94, SEE = 3.78) and obese/overweight children (r=0.83, SEE = 6.49). All ethnic groups showed significant correlation with BF%. Malay adults (r=0.92, SEE = 3.27) and children (r=0.94, SEE = 0.88) showed significant mean differences in BF%.Conclusion.The FTF-BIA showed higher accuracy for all normal/underweight and Chinese group with acceptable overestimation in children and underestimation in adults. Caution should be taken when interpreting BF% depending on gender, BMI, and ethnicity.

Football athletes require high-quality physical fitness that affects achievement. Nutritional status was the outcome of dietary intake and can influence physical fitness. Athletes who boarded have an organized eating arrangement, so the dietary intake is more assured. The objective of this study was to analyze the differences of energy, macronutrients intake, nutritional status, and V2 max between boarding and nonboarding football athletes aged 13 - 18 years. A cross-sectional study was done in 32 people who divided into two groups (boarding and non-boarding football athletes).The collected datas included food intake using 6x24 hoursfood recalls, height using microtoise, weight using digital scales, BMI for Age using WHO Anthro Plus, body fat percentage using Bioelectrical Impedance Analysis, VO2 max using Cooper Test 2.4 km. Nutrient values were analyzed using NutriSurvey. Statistical analysis using Independent TTest. There were significant differences between energy and macronutrient intake (p=0.001), body fat percentage (p=0.004), and VO2 max score (p=0.001) of boarding and non-boarding athletes. Energy and macronutrient intake of boarding and non-boarding athletes were still in the deficient category; however, the average nutritional intake of boarding athletes were still higher than non-boarding athletes. Most nutritional status of athletes based on BMI/Age were in normal category (87.5% in boarding athletes and 62.5% in non-boarding athletes). There was no over in non-boarding athlete. However, there were 12.5% of boarding athletes in the over fat category. 25% of non-boarding athletes were in the under fat category, while in boarding athletes, none of athlete in under fat category. 62.5% boarding athletes had VO2 max score at a very good level, while 87.5% of non boarding athletes were in enough category. There were significant differences between energy and macronutrient intake, body fat percentage, and VO2 max score between boarding and non-boarding football athletes.

Body composition is a determinant of performance in soccer. To estimate the body fat percentage (%BF), dual energy X-ray absorptiometry (DXA) is effective though this method is expensive and not readily accessible. This study examines the validity of widely used field methods based on anthropometric data and bioelectrical impedance analysis (BIA). Participants were 21 male Spanish First Division soccer players aged between 22 and 35 years. In each participant, body fat mass was determined by BIA and using 18 anthropometric equations including skinfold (SKF) measurements. DXA was used as reference. Correlation with DXA measurements was excellent for all equations and separate SKF measurements yet only moderate for BIA. However, only the equation recently developed for use in soccer players based on iliac crest and triceps SKFs showed no significant or standardized differences with DXA-derived %BF and these measurements also had the lowest bias. Our findings suggest that when DXA is not available, the best field method for %BF assessment in footballers is the equation based on iliac crest and triceps SKF. As another good option, we propose the sum of triceps, subscapular, supraspinal, and abdominal SKFs, as this combination also showed good correlation with DXA.
