 Abstract: The aim of the study was to compare the players characteristics and physical fitness parameters according to playing positions and to identify the relation between body composition and physical fitness in professional soccer players at the beginning of the preparation period. Sixteen professional soccer players participated in this study. Body composition was evaluated by air displacement plethysmography instrumentation (BOD POD®) and physical fitness with specific tests: Running Anaerobic Sprint Test (RAST), Counter Moviment Jump (CMJ), Squat Jump (SJ) and Abalakov jump (ABK), Yo-yo Intermittent Recovery Level 1 (Yo-yo IR1), agility test and flexibility. Kruskal Wallis test demonstrated no significant difference in all estimated body composition, age, height and physical fitness parameters according to three playing positions (p < 0.05). We verified a significant negative correlation between body fat percentage and the performance of CMJ, SJ, ABK, peak, mean and minimum power (-.51 to -.87) and a significant positive correlation with the agility parameter (r = .85). Regarding to lean mass percentage, a significant positive correlation was found with performance of CMJ, SJ, ABK and peak, mean and minimum power (.51 to -.82) and significant negative correlation with agility parameter (r = -.85). Based on the results, we concluded that at the beginning of a pre-season a higher body fat percentage is associated with a negative influence in physical fitness, thus confirming that a greater amount of lean mass percentage is positively associated with the initial level of physical fitness of professional soccer players. Resumén: El objetivo del studio fue comparar las características de los jugadores y los parâmetros de aptitud física según las posiciones de juego e identificar la relación entre la composición corporal y la aptitud física em futebolistas profisionales al inicio del período de preparación. Dieciséis futebolistas profesionales participaron em este estudio. La composición corporal se evaluómediante instrumentación de plestimografia por desplazamiento de aire (BOD POD®) y aptitud física com pruebas específicas: capacidade anaeróbia (RAST), saltos verticales (CMJ, SJ y salto abalakov- ABK), resistência aeróbia, prueba de agilidade y flexibilidad. Kruskal Wallis no demostró diferencias significativas em todos los parâmetros estimados de composición corporal, edad, altura y condición física según las três posiciones de juego (p < 0.05). Verificamos uma correlación negativa significativa entre el porcentaje de grasa corporal y el rendimento de CMJ, SJ, ABK, potencia pico, media y mínima (-.51 to -.87) y uma correlación positiva significativa com el parâmetro de agilidade (r = .85). Em cuanto al porcentaje de massa magra, se encontro uma correlación positiva significativa com el rendimento de CMJ, SJ, ABK y potencia pico, media y mínima (.51 to -.82) y correlación negativa significativa com el parâmetro de agilidade (r = -.85). Com base em los resultados, concluimos que al inicio de una pré-temporada um mayor porcentaje de grassa corporal se associa com uma influencia negativa em la aptitud física, confirmando así que uma mayor porcentaje de massa magra se associa positivamente com el nível inicial de aptitud física de los futebolistas profesionales.

Abstract Background. Appropriate physical fitness components and body composition are required to overcome dangerous situations during sea rescues and in the first line of combat in the Mexican Navy. Aim of the study. To analyze the impact of body composition on physical fitness components such as cardiorespiratarory fitness and muscle strength-resistance of marines, rescue swimmers, and divers of the Mexican Navy classified as overweight. Methods. BC was assessed by two BMI cutoff points (WHO and military)­; body fat percentage and muscle mass percentage, and waist circumference were determined by anthropometry. Cardiorespiratory fitness was assessed by the Course-Navette test and MSR by a 1-minute maximal effort of push-ups, sit-ups, and bench presses. Results. We found significant differences in medians of physical fitness components and body composition among groups (p < 0.001). The WHO and military BMI showed 59 (54%) and 16 (15%) individuals as overweight, respectively. Marine instructors showed the highest percentage of men to be overweight, 24 (41%) (WHO) at the expense of good muscle mass percentage but high body fat percentage according to age. All groups showed cardiorespiratory fitness adequate for their age, but only 26 (51%) and 14 (24%) classified as normal and overweight (WHO), respectively, had good cardiorespiratory fitness (p = 0.003). Conclusions. Personnel classified as overweight had good body composition at the expense of high body fat percentage but adequate muscle mass, which could be adequate for their operational tasks; but their cardiorespiratory fitness, although good for their age, is still below the ideal value for military physical activity.

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.

AbstractThe feasibility and acceptability of using the Bod Pod procedure to measure changes in body composition in 30 adolescent females admitted to an inpatient eating disorder unit was evaluated using written surveys, Bod Pod measurements obtained at admission and discharge, and medical records review. Participants rated the Bod Pod test as acceptable (100%; 30/30), comfortable (93%, 28/30), and they were willing to repeat the procedure (97%, 29/30). Ten participants did not complete the final Bod Pod: eight were discharged before a second measure could be obtained, one refused the test, and one left against medical advice. Three participants had undetectable readings at admission. Paired t-tests (n = 17) revealed a significant (p < 0.001) mean increase in fat mass (3.7 ± 2 kg), body fat percentage (6.6 ± 3.8%), and lean mass (1.4 ± 1.2 kg) from admission to discharge. The Bod Pod is a feasible and acceptable procedure to measure changes in body composition in adolescent females hospitalized with an eating disorder.

Introduction: Adolescents are at increased risk for the development of obesity, while sport has been suggested as an effective means against adolescent obesity. The objectives of this study were to examine (a) the prevalence of overweight/obesity, (b) the relationship between body mass index and body fat percentage, and (c) the association between body mass index, body fat and physical fitness in soccer players aged 16-18 yr. Material and Methods: Members (n=109, aged 17.0?0.5 yr) of competitive soccer clubs were examined for physical and physiological characteristics. Results: Based on international body mass index cut-off points, 18.3% (n=20) of participants were classified as overweight. Body mass index was highly correlated with body fat percentage (r=0.70, p<0.001). Body fat percentage was in inverse relationship with aerobic power (r=-0.21, p=0.029), maximal anaerobic power (r=-0.20, p=0.044) and local muscular endurance (r=-0.39, p<0.001), while corresponding values of body mass index were non-significant (r=-0.05, p=0.614; r=0.03, p=0.771; r=-0.12, p=0.220, respectively). However, both body fat percentage and body mass index were inversely related with fatigue index of Wingate anaerobic test (r=-0.26, p=0.009; r=-0.29, p=0.003, respectively). Conclusions: The strong relationship between body mass index and body fat percentage suggest the further use of body mass index in adolescent soccer players. The findings confirmed previous observations on general population about the negative effect of overweight and fatness on physical fitness. The prevalence of overweight among participants was similar with what is observed in general population. Therefore, sport participation cannot guarantee physiological body mass and body composition, and it is necessary to prescribe exercise targeting body mass and fat control.

Abstract The number of studies related to soccer has been growing exponentially in the last years because the modality is considered the most popular in the world. It is known that the development of some specific physical capacities, even in young individuals, is essential to high-level performance and these capacities might be related to anthropometrics variables. The purpose of this study was to verify the relationship between body composition and physical capacities in young soccer players. Study participants were athletes from junior categories (under-12 and under-13) belonging to the Soccer Association of Chapecó, Brazil.. Athletes were submitted to agility, (Illinois), vertical jump (Sargent Jump), aerobic condition (TCAR), flexibility and sit-and-reach (Wells Bench) tests, as well as anthropometric assessment. All procedures were performed at UNOESC campus, Chapecó. Statistical analysis consisted of the Spearman’s Rô test, measuring the correlation among variables, additionally, significance level of p<0.05 was adopted. Results showed significantly correlation in agility (p=0.000; ρ=0.530) and vertical jump tests (p=0.003; ρ=-0.437) with body fat percentage. It was concluded that there is relationship between body fat percentage and agility and explosive power of lower limbs.

BACKGROUND: The Functional Movement Screen (FMS) is a clinical assessment tool used to determine musculoskeletal dysfunctions and asymmetries in athletes. OBJECTIVE: The aim of this study was to investigate whether FMS scores differed between elite youth male soccer players with low body fat percentage and those with normal body fat percentage and between those with and without a history of soccer injury. METHODS: Fifty-three elite youth male soccer players were included in the study. The participants’ injury histories were recorded, followed by body composition assessment and FMS tests. The participants were grouped according to body fat percentage and injury history for data analysis. RESULTS: The mean age, weight and height of the participants were 17.11 ± 0.91 years, 68.78 ± 7.41 kg and 1.77 ± 0.57 meters, respectively. Comparisons of the groups according to body fat percentage and injury history revealed no significant differences in FMS scores (p> 0.05). CONCLUSION: Lower body fat percentage did not confer an advantage or disadvantage to elite youth male soccer players in terms of FMS scores FMS scores provide limited information to predict injuries in elite youth male players.

The Relationship

The aim of this study is to analyze the relationship between body composition and physical fitness parameters in children. 286 male and 311 female students have voluntarily participated in the study. Data on body composition have been obtained through the measurements of the students’ height, body weight, BMI, body fat percentage, length (sitting height, arm length, forearm length, leg length, thigh lengths), circumference (elbow, shoulder, biceps (flexion) , buttock, knee, waist, calf, ankle). For somatotype characteristics, the Heat-Carter somatotype grading method has been used. The Sit-Reach Flexibility Test (cm) has been used to determine the characteristic of flexibility; the 20 m. Speed Test (seconds) to determine speed; the 20 m. Sit-up test to determine endurance; Takkei hand dynamometer to determine right-left hand grip strength; Takkei back and lift dynamometer for leg strength and the Flamingo Balance Test for balance have been used. In the analysis of data, the SPSS 16 software has been used and T test and Pearson correlation test have been carried out (p&lt;0.05). Between the body composition and physical fitness parameters of female and male students, a statistically significant relationship has been found with the exception of age, arm and waist measurements (p&lt;0.05). In both genders, positive or negative relationships have been found between height, circumference measurements and somatotype characteristics and performance tests (p&lt;0.05). It was found that there is a negative or positive relationship between the heights, circumference measurements and somatotype characteristics and their strength, endurance, speed, flexibility and balance characteristics of female and male children aged 10-12. As a result, it has been seen that the body composition of children aged 10-12 affects the physical fitness parameters. Children in this age group which is both a period of growth and development and skills selection period for numerous sports branches should regularly be followed by their physical education teachers, anthropometric measurements and performance tests should be carried out and the children should be directed towards suitable sports branches.

Thirty-four volunteer obese housewives, who have not done exercise regularly during the last six months and have had no health problems to prevent them from exercising, have participated in the study. For the participating volunteers (n = 34), their age averages have been determined as (39.30 ± 11.30 years), their average height have been determined as (166.40 ± 8.50 cm) and their average body weights have been determined as (82.44 ± 15.02 kg), their average BMIs have been determined as (26.03 ± 6.65 kg/m2) and their average body fat percentages have been determined as (32.17 ± 8.05 %). The volunteers have been given an aerobic exercise program at 75% an exercise intensity according to the Karvonen formula for 50 minutes a day and for 4 days a week during 12 weeks. Measurements (body weight, waist circumference, body fat percentage) of the volunteers have been taken at the beginning and the end of the 12-week aerobic program. The data have been analysed by using the SPSS 17.0 statistical package program. Statistical analyses have been made by using Wilcoxon Test and the significance value has been determined as p< 0.05.After the statistical analysis, statistically significant difference have been detected between the preliminary and the final test values of the subjects in terms of Body Weight (z=-5.08, p<0.05), Waist Circumference (z=-5.08, p<0.05), Body Fat Percentage (z=-4.71, p<0.05) and Body Mass Index (z=-4.57, p<0.05).As a result, it has been determined that aerobic exercise of 12 weeks in aerobic style has positive effects on physical fitness parameters of obese housewives. For this reason, the importance of the cost-free aerobic exercise in the right intensity for every age has been revealed again.
