DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p371 Among volleyball skills, spike is responsible for the highest number of scores, and the first tempo of attack is related to the higher incidence of score a point, by hindering the defensive opponent’s action. However, most of the studies show general results and do not specify the conditions and constraints of each attack zone. Thus, the aim of this study was analyzing the offensive game (complex I) performed by the middle attacker at the 2014/2015 National men’s Brazilian Championship (Superliga). The sample wascomposed by 142 games of 12 teams, totaling 5350 receptions, setting and spikes actions. The results showed that the middle spikes occurred mostly after receptions A and B, being the most frequent attack scoring point as well as the most powerful one. Moreover, the relationship between the reception effect and setting effect was observed, showing that the best receptions influenced the setting type and the attack effect. Therefore, the middle attack had effective effect in the winning score, since it decreased the chances of opponent’s defense, due to the reduced time to defensive organization. Finally, the situational constraints delimited the middle attacker actions. Based on the above, we suggest that future studies should restrict the analysis conditions and situational constraints of each specific game situation.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p381 The aim of this study was to compare body adiposity indexes and to identify cutoff values in the prediction of disability in older women. Eighty-seven voluntees (67.27±6.45 years) underwent body composition assessment using dual-energy X-ray absorptiometry (DXA) and had five anthropometric indexes measured (Waist Circumference, WC; Waist-to-Height Ratio, WHtR; Body Mass Index, BMI; Body Adiposity Index, BAI; and conicity index). Functionality was assessed from three Senior Fitness Test Battery protocols: 30-second chair stand, 8-foot up-and-go, and 6-minute walk. Pearson’s correlation was conducted to identify the relationship between body adiposity indexes and functionality results. Cutoff values to predict disability were obtained from ROC curves and odds ratio were calculated for the same outcome. Disability prevalence was 36.8%. Scores in the 30-second chair stand, 8-foot up-and-go, and 6-minute walk tests showed stronger associations with WC (r=-0.345; p<0.01), WHtR (r=-0.417; p<0.01) and BAI (r=0.296; p<0.01), respectively. The cutoff values identified were 89.5cm, 39.2%, 26.93kg/m2, 34.6%, 0.51cm and 1.23 for WC, DXA-derived body fat percentage, BMI, BAI, WHtR and conicity index, respectively. WC showed greater odds ratio for disability outcome (odds ratio: 3.16; CI: 1.3–7.8). WC showed strong relationship with functional tests and its cutoff values exhibited predicting skill for disability in older women.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p411 Pedaling asymmetries quantified during stationary cycling, when cyclist body positioning and intensity remain unchanged, may not fully reproduce the training and competition situations, in which cyclists experience different intensities and may opt for different saddle positioning aiming at power output optimization. Previous studies showed that torque and power can be asymmetric in cyclists. It is not clear whether changes in saddle height and exercise intensity may affect asymmetries. The aim of the present study was to determine pedaling asymmetries during cycling at different saddle heights and different exercise intensities. Twelve competitive cyclists performed an incremental maximal test, a constant-load (“heavy” intensity domain), and a Wingate test. Constant load and the Wingate tests were repeated using three different saddle heights (reference and lower or higher by 2.5% of the distance from the pubic symphysis to the ground). Crank torque was recorded throughout the pedaling cycle. Asymmetry (higher torque for the preferred limb) was found in all saddle heights (p<0.001) in both intensities. Asymmetry index was similar across the saddle positions (p>0.05) in both intensities. Our results suggest that asymmetric cyclists present a consistent pattern regardless of small changes in the saddle height or in exercise intensity. For practical implication, cyclists producing asymmetric torque may be adapted to this condition so they are continuously exposed to asymmetric effort and overload on the lower limbs.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p419 The aim of the present study was to analyze the development of postural balance in 4- to 10-year-old Brazilian children, compared to a group of young adults under normal and deprived visual conditions. Body sway was assessed through average velocity and sway range at the center of pressure (CoP) in the anteroposterior and medio-lateral directions, obtained on a force platform (AMTI, Inc.). Sample was composed of 153 children (of seven different age groups) and 47 adults. Inter-group comparisons were performed using one-way ANOVA and Tukey’s post-hoc test at 5% significance level. The results showed that starting at 9 and 10 years of age, CoP velocity and displacement values for children were similar to values for adults under restricted visual conditions; however, there were differences between children and adults. The findings suggest that visual stimulation plays a prominent role in the balance of individuals up to 10 years of age, with significant evidence that postural balance is not fully developed up to that age.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p441 This study aimed to verify the association between health-related physical fitness and academic performance in adolescents. Overall, 326 students aged 15-18 years of the Federal Institute of Sergipe (IFS) participated in this cross-sectional study. Data relating to physical fitness were collected by applying the following tests: body mass index, sit and reach, abdominal in one minute and one mile running, which comprise the American Alliance for Health, Physical Education, Recreation and Dance testing battery. Academic performance was measured by the grades of two-month period in the disciplines that comprise the following areas of knowledge: languages and codes, natural sciences and humanities, obtained from the IFS school record. Students with average grades ≥ 6.0 were considered on satisfactory academic performance. The prevalence of physical unfitness in the sample was 15.8% (girls 15.4%; boys 16.4%) in body composition, 32.3% (girls 23.1%; boys 41.5%) in flexibility, 93.0% (95.8% girls; 90.2% boys) in muscular strength and 86.9% (85.3% girls; 88.5% boys) in cardiorespiratory endurance. On academic performance, the prevalence of adolescents below the average grade was 8.8% (girls 5.6%; boys 12.0%) in languages and codes, 24.5% (girls 19.5%; boys 29.5%) in natural sciences and 12.8% (girls 11.9%; boys 13.7%) in humanities. Adolescents with low cardiorespiratory endurance levels were more likely to have worse academic performance (OR=2.39; CI95%=1.05 to 5.44). It was concluded that low cardiorespiratory endurance levels were associated with worse academic performance.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p460 The aim of the research was to analyze the association of physical activity (PA) intensity and duration with male aging symptoms. This is a cross-sectional study of probabilistic sample involving 416 men from two cities in southern Brazil. Data collection used a questionnaire divided into six parts: sample characteristics; anthropometric measurements; economic level by the Brazilian Institute of Geography and Statistics (IBGE); International Physical Activity Questionnaire (IPAQ short-version); Behavioral Risk Factors Surveillance System Questionnaire (BRFSS) and Male Aging Symptoms Scale (AMS). The sample was divided into two groups: with and without male aging symptoms, making use of descriptive and inferential statistics. The presence of male aging symptoms was identified in 61.6% of men, especially somatic and psychological symptoms. Most were considered sufficiently active (60.1%), highlighting men without male aging symptoms (p = 0.026), with a possible effect of moderate and total PA on low-intensity symptoms (p = 0.027; p = 0.015). This study identified relationships between PA duration and intensity and intensity of male aging symptoms. PA practice with specific intensity and duration is suggested in order to obtain health benefits related to male aging symptoms.

We conducted a phone survey with 914 Secretary of Health from cities that received funds until July/2012. We calculated prevalence (%) of health promotion actions, expected results, number of people that would be assisted, partners for actions, health professionals in actions, manager group for coordinate and main objectives for proposal the actions. The most of the cities were of the south (25.9%) and southeast (33.4%). The actions would provide reach over one million of people in 25% of the cities. Improves of physical activity and healthy food are priorities in the actions. The most of cities had partners for actions. Only 50% of the cities had used health indicators for planning the program and 25% of the cities had planned training for health professionals and manager group for coordinate the program. The actions had focus in physical activity and healthy food. A large of number of people would be reach in actions. Only half of cities used health indicators for plan and few cities planned professional training and manager group. It is necessary improve the use of health indicators for plan, training of professionals and developing manager group for coordinate the actions. The continuum evaluation these program to verify possible effectiveness results in physical activity level and healthy food of population is a challenge for the Ministry of Health.

Published: December 2017

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p493 The International Classification of Functioning (ICF) was elaborated by the World Health Organization (WHO) in order to unify the language among health professionals within the biopsychosocial model. ICF contains domains that resemble conceptual aspects and practical perspectives of functional training (FT). There is a consensus limitation of which aspects should be considered about the term “functionality”, in addition to being notorious the little use of ICF in physical activity programs. The aim of this approach study was to support the practical application of ICF as an easy way to complement functional evaluation in FT methods. Discussions were held on how the term “functionality” can be better understood in physical activity programs as well as some possibilities to make ICF in FT more operational. The absence of evidence about the use of ICF in relation to sports science elucidates the need of this approach, which may contribute to expand the knowledge about individuals’ functional health.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p509 The aim of this study was to analyze the association between diseases and chronic health conditions, multimorbidity and body mass index (BMI) in older adults from southern Brazil. Epidemiological cross-sectional study, with household basis was carried out with 343 older adults aged 60-79 years, selected by probability sampling and all aged 80 years or older (n=134). Hypertension, diabetes, cancer, chronic pulmonary diseases, coronary heart disease, cerebrovascular disease, arthritis, osteoporosis, depression, history of falls and dependency in activities of the daily living were assessed by self-report. Associations between independent variables and BMI (outcome) were tested using simple and multiple linear regression. Participated in the study 270 women (73.2±8.8 years) and 207 men (73.3±9.0 years). After adjustment (age, education, living arrangement, smoking, alcohol consumption, waist circumference, cognitive status and all other disease and chronic health conditions), the associations identified were: hypertension with higher BMI values (β 3.43; 95%CI: 2.38 to 4.48), for women, and chronic pulmonary disease with lower BMI values (β -2.05; 95%CI: -3.50 to -0.60). There was a linear trend between number of diseases and BMI for both sexes. Conclusion: The results showed an independent association between specific chronic diseases and BMI. Monitoring of nutritional status in older adults is important to identify extreme BMI values, especially those with more than two diseases and chronic health conditions.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p520 The aim of this study was to estimate the prevalence of commuting physical activity and associate sociodemographic, behavioral and health characteristics in longlived older adults of Florianópolis/SC. This cross-sectional epidemiologic study included 343 individuals aged 80 and older; these individuals are members of community groups registered in the municipality of Florianópolis/SC. Sociodemographic information and health and behavior data were collected. To assess physical activity, the “commuting” domain of the International Physical Activity Questionnaire (IPAQ) was used, adapted for older adults. Data were analyzed using Stata 11.0 with Logistic regression expressed in odds ratios and 95% confidence interval. The prevalence of commuting physical activity was 19.5%. The oldest members of the group (p= 0.011; OR= 0.90; 95%CI= 0.83/0.98), with worse health perception (p< 0.001; OR= 0.33, 95%CI= 0.18/0.60) and with hypertension diagnosis (p= 0.009; OR=0.47; 95%CI= 0.27/0.83) had lower odds ratio of commuting physical activity. Knowledge about sociodemographic, behavioral and health characteristics associated with commuting physical activity can serve as a basis for the development of programs and actions to encourage commuting physical activity among long-lived older adults.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p530 Anthropometric indicators enable professionals for predicting risk of falls in the elderly; however, there is a gap in literature on reference values. This study analyzes anthropometric indicators such as screening tests for falls in the elderly. Cross-sectional population-based systematic sampling was conducted through a household survey and body composition assessment. Anthropometric measurements were performed using portable electronic scale and stadiometer. Bioimpedance device was used to measure body mass index, body fat and lean body mass. Falls were evaluated in the 12 months preceding the interview as a dependent variable. Discriminatory analysis was performed for falls through the ROC curve, sensitivity, specificity, positive and negative predictive values. Overall, 275 older adults participated in this study, whose prevalence of falls was 23.6%. The average body mass index was 27.8kg/cm2 and 52.1% of individuals were overweight. Among older men, height (ROC=0.68; 95%CI 0.54-0.78) and lean body mass (ROC=0.63, 95%CI 0.58- 0.76) were associated to the occurrence of falls. When considering cutoff of 52.2kg and 166cm, sensitivity was obtained in 75% and high negative predictive values (88.1% and 89.1% respectively). For women, lean body mass (ROC=0.61, 95%CI 0.30-0.49) and body mass (ROC=0.60, 95%CI 0.53-0.72) were relevant from the optimal cutoff point of 28.9% and 57.2kg/m2. Lean body mass was more sensitive (63.2%) and body mass little more specific (64.3%), both with high negative predictive values (82.0% and 83.0%). The indicators used were able to discriminate older adults who have suffered from falls.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p539 Many researches have concluded that the time spent in front of TV, computer and other screen-type devices is an important risk factor for overweight and obesity. The aim of this study was to identify the discriminatory power and to propose screen time cutoff points for overweight, obesity and abdominal obesity in adolescents. This household survey had cross-sectional design with sample of 613 adolescents aged 15-18 years living in a city in northeastern Brazil. The predictive power and cutoffs points of screen time for the outcomes of interest were identified by receiver operating characteristic curves (ROC). The study adopted 95% confidence interval (CI). Screen time during one day on the weekend was a good discriminator for the presence of overweight only among girls, area under the curve ROC = 0.59 (0.51 to 0.65). There were no areas under the ROC curve with statistical significance to discriminate obesity and abdominal obesity. Remain sitting for accumulated four hours per day during the weekend discriminates presence of overweight among girls (sensitivity = 60.9%, specificity = 52%). The long time spent in front of TV, computer and other screen-type devices on the weekend discriminate overweight in girls.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p548 The aim of this study was to evaluate the diagnostic accuracy of body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR) and conicity index (C index) for the prediction of excess body fat (estimated by skinfold thickness) and determine the cutoffs of anthropometric indicators (BMI, WC, WHtR and C index) that best predict excess body fat. Overall, 1,589 students (11-14 years old) from public and private schools of Florianopolis (southern Brazil) participated in this study. Anthropometric measurements of body weight, height, WC, and skinfolds (triceps and medial calf) were collected. ROC curves were used to compare the discriminatory power of BMI, WC, WHtR and C index in detecting adolescents with excess body fat (relative body fat estimated with skinfold thickness). All anthropometric indicators, except for C index in females, obtained good performance in the detection of excess body fat in both sexes, expressed as the area under the ROC curve. Cutoffs for boys and girls, respectively, associated with high excess body fat were BMI (20.7 and 19.7kg/m²), WC (68.7 and 65.9cm), WHtR (0.43 and 0.41cm), and C index (1.13 and 1.11). The study showed that, except for C index in females, BMI, WC and WHtR can be used to identify excess body fat in adolescents, considering the suggested cutoffs from this research.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p557 Excess body fat is associated with chronic degenerative diseases, being a global public health problem. The aim of this study was to investigate the association of obesity with sociodemographic factors, lifestyle (physical activity, dietary habits) and sexual maturation in high school students of a city in southern Brazil. This is a crosssectional study with 820 adolescents enrolled in public high schools of São José, Santa Catarina, Brazil, aged 14-17 years. Obesity was estimated by body fat percentage (BF%). BF% was calculated using the Lohman equation, which considers the sum of skinfolds (triceps and subscapularis). Cutoff points proposed by William et al. were used to classify individuals into normal weight or obese. Independent variables were sex, age, economic status, parental education, eating habits, physical activity and sexual maturation. The prevalence of obesity was 17.2%. Females (OR: 4.22; 95% CI: 2.72-6.54) and young people at post-pubertal stage of sexual maturation (OR: 1.95; 95% CI: 1.33-2.86) were more likely to have obesity. These results may help health authorities in the planning of public policies to prevent obesity.
