The objective of this work was to compare the anthropometric and physical fitness characteristics of Brazilian adolescents who practise team court sports and to compare specific parameters obtained for adolescents with data from the general population. This was a cross-sectional study of 1,348 male adolescents grouped as follows: basketball players (n = 287), indoor soccer players (n = 665), handball players (n = 108) and volleyball players (n = 288), all between 10 and 14 years of age. Anthropometric (body mass, body height, arm span, and body mass index) and physical fitness data (flexibility, muscular strength, explosive power, speed, aerobic fitness and agility) were collected. The Brazilian population was used as a reference and compared to the adolescent subjects using Z scores for all variables. Anthropometric characteristics and performances in physical fitness tests differed (p<0.05) among players of different sports. In addition, for each variable assessed, adolescents who practised team court sports showed similar or improved results compared to their counterparts in the general population (p<0.05). Furthermore, the anthropometric and physical fitness characteristics differed depending on the team court sport practised. These findings may elucidate which physical abilities are most impacted by the practise of a particular team sport as well as help teachers and physical education and sport professionals identify talented adolescents.

Purpose. Sedentary behavior has been identified as a risk factor for chronic non-communicable diseases. This study identified the prevalence of excessive TV viewing time during the week and weekend and associated factors in adolescents living in a small urban and rural area. Methods. A cross-sectional study involving 283 students (aged 10-19 years) from Brazil was conducted in 2010. Data on TV viewing time and sociodemographic information were collected by questionnaires, cardiorespiratory fitness was evaluated by the 20-m shuttle run test, and anthropometric characteristics were obtained by measuring waist circumference and skinfold thickness. Statistical analysis involved binary logistic regression. Results. The prevalence of excessive TV viewing time ( 2 h) was 76.7% during on weekdays and 78.4% on the weekend. Adolescents aged 10-12 years (OR = 6.20; 95% CI = 2.91, 13.19; p < 0.001) and 13-15 years (OR = 2.57; 95% CI = 1.28, 5.18; p = 0.008) were more exposed to excessive TV viewing time during the week. No associations were found for excessive TV viewing time on the weekend. Conclusions. Approximately 8 in 10 adolescents presented excessive TV viewing time; excessive TV viewing time during the week was associated with age.

Purpose. To determine the prevalence of the presence of concomitant low health-related physical fitness components with sociodemographic factors among Brazilian adolescents living in a small town of German colonization. Methods. A cross-sectional epidemiological study on adolescents (10 to 17 years old) from the public schools of Sao Bonifacio, Santa Catarina, Brazil (N = 277) was conducted. The FITNESSGRAM test battery was applied to assess three physical fitness components (body composition, cardiorespiratory and muscular fitness). Data on age (split into two age groups of 10-12 and 13-17 years), gender (male/ female), area of residence (rural/urban) and socioeconomic status (low/high) were collected by a questionnaire. Maturity, determined by pubic hair development, was self-assessed. The analyzed physical fitness components were analyzed in terms of the groups of three possible combinations that featured two physical fitness components concomitantly. Adjusted binary and multinomial logistic regression was applied, adopting a confidence level of 95%. Results. 75.4% of boys and 88.5% of girls showed unsatisfactory levels for health in at least one physical fitness component. Girls living in rural areas were more likely to have combinations of excess body fat with low muscular fitness (OR = 5.06, 95% CI [1.31, 19.61]), low muscular fitness with low cardiorespiratory fitness (OR = 5.46, 95% CI [1.24, 23.94]) and feature two (OR = 8.82, 95% CI [1.60, 48.49]) low values of the components regardless of which combination. Boys aged 10-12 years were less exposed to lower fitness levels compared to those with satisfactory levels (OR = 0.09, 95% CI [0.01, 0.61]). Conclusions. More effective measures aimed at promoting physical fitness among adolescents are needed, where special attention should be given to boys aged 10-12 years and girls aged 13-17 years and living in rural areas.

Purpose. The aim of this study was to verify and analyze the association between anthropometric indicators and serum lipid profiles in adolescents. Methods. The study included 250 adolescents aged 11-17 years from both sexes. The anthropometric variables measured were body weight, height and waist circumference. Body mass index and waist circumference were used to calculate a nutritional status rating (whether normal weight or overweight) and abdominal obesity, respectively. Total cholesterol, high-density lipoproteins, low-density lipoprotein and triglyceride levels were determined by an enzymatic colorimetric method using automatic spectrophotometry and were categorized according to cutoff points established by the III Brazilian Guidelines on Dyslipidemia and Atherosclerosis Prevention from the Brazilian Society of Cardiology. Results. The overweight and abdominal obesity prevalence was found to be 23.6% and 40.0%, respectively. Undesirable total cholesterol, high-density lipoprotein, low-density lipoprotein and triglyceride levels were found in 40.8%, 8.4%, 36.0% and 13.6% of the studied adolescents, respectively. Overweight adolescents were 2.29 (CI 95%, 1.07-4.91) times more likely to have high triglyceride levels, and those with abdominal obesity were 2.47 (CI 95%, 1.14-5.37) times more likely to show high triglyceride levels. Conclusions. A high prevalence of overweight and abdominally obese adolescents, with high levels of serum lipid profiles, were observed. Moreover, overweight and abdominally obese adolescents were more likely to have high triglyceride levels.

The aim of this study was to identify the morphological configuration of youth athletes from professional soccer clubs and to verify their differences according to the tactical position on the field. Overall, 67 male players aged 15 to 17 years were evaluated. The examined anthropometric measurements included body mass, body height, skinfolds (triceps, subscapular, supraspinal and medial calf), girths (flexed and tensed arm and calf) and breadths (humerus and femur). For statistical purposes, analysis of variance and post hoc Bonferroni and Kruskal-Wallis tests were used. We concluded that goalkeepers were heavier and taller than center backs (p = 0.015 and p = 0.001), midfielders (p = 0.005 and p <0.001) and center forward players (p = 0.024 and p <0.001). The average somatotype for defense, forward and goalkeeper positions was a balanced mesomorph. Midfield players showed ectomorphic-mesomorph characteristics. It was concluded that goalkeepers were characterized as being taller and heavier and that somatotype features of athletes were similar between positions, except for midfield players
