DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n1p82 The evaluation of psychological factors can help preventing eating disorders in athletes. This study aimed to verify possible links between body dissatisfaction and media influence, perfectionism, mood and risk behavior for eating disorders and to compare the study variables among artistic gymnastics elite and non-elite athletes and non-athletes. Participants were 413 adolescents of both sexes (elite and non-elite athletes and non-athletes), aged 10-18 years (mean age 12.86 ± 1.80). BSQ, EAT-26, SATAQ-3, MPS and BRUMS were applied to evaluate body dissatisfaction, risk behavior for eating disorders, media influence, perfectionism and mood, respectively. Anthropometric data were collected to estimate body mass index (BMI) and body fat percentage (%BF). Descriptive statistical, comparative and correlational analyses were held. Only EAT-26 influenced BSQ in the three groups. In non-athletes, BMI, BRUMS and SATAQ-3 added explanation to the model. For non-elite athletes, %BF, media influence and mood were also predictors of body dissatisfaction. Elite athletes had lower BMI and %BF than the others. Non-athletes had lower perfectionism scores while non-elite athletes athletes had lower mood scores. It could be concluded that the risk behavior for eating disorders is the factor most strongly related to body dissatisfaction among elite and non-elite athletes and non-athletes.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n1p93 Low back pain is increasing considerably among adolescents, reaching proportions similar to the adult population. Flexibility (Flex) and muscle strength/resistance, components of Health-Related Physical Fitness (HRPF), seem to be associated with presence of low back pain. The aim of this study was to assess the ability of Flex and muscle strength/resistance in the screening of adolescents with low back pain and to propose cutoff points for these HRPF components. The study was conducted with 1.455 students aged 10-17 years randomly selected. Low back pain was estimated using a questionnaire. Flex was measured by the sit and reach test and muscle strength/resistance by the one minute sit up test. The analysis of the receiver operating characteristic (ROC) curve was used to identify the capacity of Flex and muscle strength/resistance for screening low back pain. To propose cutoffs points, the best balance between sensitivity and specificity was analyzed. The frequency of low back pain was 16.1 %, higher (p<0.05) among females (21.6%) than in males (10.5%). The ROC curve analysis indicated that Flex is able to identify girls more likely of having low back pain (p<0.05). Sit and reach test and the proposed cutoff points can be used as screening tool of female adolescents more likely of having low back pain.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p155 The aim of the present study was to evaluate the effects of human head hair on performance and thermoregulatory responses during 10-km outdoor running in healthy men. Twelve healthy males (29.5 ± 3.7 years, 174.9 ± 4.3 cm, 72.7 ± 3.2 kg and VO2max 44.6 ± 3.4 ml.kg-1.min-1) participated in two self-paced outdoor 10-km running trials separated by 7 days: 1) HAIR, subjects ran with their natural head hair; 2) NOHAIR, subjects ran after their hair had been totally shaved. Average running velocity was calculated from each 2-km running time. Rectal temperature, heart rate and physiological strain index were measured before and after the 10-km runs and at the end of each 2 km. The rate of heat storage was measured every 2 km. The environmental stress (WBGT) was measured every 10 min. The running velocity (10.9 ± 1 and 10.9 ± 1.1 km.h-1), heart rate (183 ± 10 and 180 ± 12 bpm), rectal temperature (38.82 ± 0.29 and 38.81 ± 0.49oC), physiological strain index (9 ± 1 and 9 ± 1), or heat storage rate (71.9 ± 64.1 and 80.7 ± 56.7 W.m-1) did not differ between the HAIR and NOHAIR conditions, respectively (p>0.05). There was no difference in WBGT between the HAIR and NOHAIR conditions (24.0 ± 1.4 and 23.2 ± 1.5ºC, respectively; p=0.10). The results suggest that shaved head hair does not alter running velocity or thermoregulatory responses during 10-km running under the sun.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p166 The aim of this study was to develop an upper limb muscle power (PUL) prediction model using the Medicine Ball Throw Test (MBT) in rugby players. Eighteen amateur rugby players underwent the MBT test and the guided bench press exercise at 30, 40, 50 and 60% of 1. Myotest® accelerometer was positioned on the bench press bar to estimate muscle power. Linear regression was used to derive the upper limb muscle power prediction equation from the MBT distance. The residue analysis estimated the residual error of the predicted values using values obtained by Myotest®. Bland-Altman plots were used to verify agreement between actual and predicted upper limb muscle power, both in absolute Watts (W) and relative terms (W/kg of fat-free mass). There were significant correlations between actual and predicted upper limb muscle power (r = 0.834, 0.854, and 0.872) for intensities of 30%, 40% and 50%, respectively. Absolute bias of predicted values was -1.87 W (p <0.05). For muscle power predicted relative to fat-free mass, bias was 0.782 W/kg (p <0.05). Conclusion: The MBT test has high correlation with actual PUL values and it was found that the equation developed in this study has high accuracy to predict PUL in rugby players of both sexes.

Published: December 2017

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p187 Although the tri-set system is widely adopted by athletes and experienced weight training practitioners aimed at optimizing the metabolic overload, there are still few works in literature on the effect of exercise order manipulation on this training system. Therefore, this work was aimed at investigating the effect of exercise order manipulation on the number of repeats and training volume using the tri-set system for lower limbs. This is a randomized cross-over design study. The experimental group consisted of 14 healthy men (23.53 ± 5.40 years; 24.51 ± 2.96 kg/m2). Subjects were submitted to two experimental sessions at different exercise order for lower limbs: Sequence A: squat on guided bar, leg press 45° and bilateral leg extension; sequence B: bilateral leg extension, leg press 45° and squat on guided bar. Three sets to volitional fatigue in all exercises were performed, with intensity of 75% 1RM. Superiority for sequence B in the total number of repeats (70.14 ± 13 vs 60.93 ± 7.94 repeats, p = 0.004) and total training volume (9129.64 ± 2830.05 vs 8238.29 ± 2354.20 kg, p = 0.014) was observed. Based on the above, the performance of single-joint exercises before multi-joint exercises in the tri-set system adopted for lower limbs induced higher number of repeats and total training volume.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p197 The purpose of this study was to determine the level of agreement between critical power (CP) and intensity corresponding to 50% of the difference (50% Δ) between oxygen uptake (VO2) at lactate threshold (LT) and maximal oxygen uptake (VO2max) in untrained subjects during cycling exercise. Fifteen healthy male subjects (age: 26.0 ± 3.5 years; body weight: 76.6 ± 10.4 kg; height: 178.2 ± 7.6 cm) volunteered to participate in the study. Each subject performed a series of tests to determine LT, VO2LT, CP, VO2CP, 50% Δ, VO250% Δ, and VO2max. The values of LT, VO2LT, CP, VO2CP, 50% Δ, VO250% Δ and VO2max were 109 ± 15 W, 1.84 ± 0.23 L.min-1, 207 ± 17 W, 2.78 ± 0.27 L.min-1, 206 ± 19 W, 2.77 ± 0.29 L.min-1, and 3.71 ± 0.49 L.min-1, respectively. No significant difference was found between CP and 50% Δ (t = 0.16; p = 0.87) or between VO2CP and VO250% Δ (t = 0.12; p = 0.90). However, the bias ± 95% limits of agreement for comparison between CP and 50% Δ and between VO2CP and VO250% Δ were 1 ± 27 W (0.3 ± 14.1%) and 0.01 ± 0.24 L.min-1 (0.2 ± 8.9%), respectively. In summary, the mean CP and 50% Δ values were not significantly different. However, considering the limits of agreement between the two intensities, CP estimated based on 50% Δ might result in a remarkable error when the absolute variability of individual differences is taken into account

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p207 This study aimed to examine the validity and reliability of scales of intrapersonal, interpersonal, and environmental factors associated with physical activity (PA) in secondary students. Two cross-sectional studies were conducted with students in 7th to 9th grades form secondary schools in order to test the validity, internal consistency (n = 1,178, 51.4% were boys), and test–retest reproducibility (n = 194, 56.2% were boys) of the instrument. Factors associated with PA (attitude, self-efficacy, social support of friends, parents and the school’s teachers, as well as the perceived neighborhood environment and perceived school environment) were measured. The confirmatory factor analysis and Spearman correlation between the scales and the weekly time spent in moderateto-vigorous PA (measured by questionnaire) were applied to test the construct validity. For reliability, the Cronbach’s α (internal consistency), composite reliability (CR) and intraclass correlation coefficient (ICC for test–retest reproducibility) were applied. The confirmatory factorial analysis showed five one-dimensional and two two-dimensional (self-efficacy and perceived environment) scales, with factor loadings ranging from 0.46 to 0.85. Significant and positive correlations between almost all scale scores and moderateto-vigorous PA (p<0.05) were found. The Cronbach’s α and CR were greater than 0.70 in almost all scales (except perceived school environment, α and CR of 0.61) and the ICC ranged from 0.62 (parental social support) to 0.70 (self-efficacy). In conclusion, the scales showed acceptable validity and reliability and can be used for measuring of PA correlates in elementary students.

The objectives of the study were to compare the proportions of practice team sports in the years 2010, 2012 and 2014 in college and to analyze the association between participation in the classes of Physical Education, before entering university, with the practice team sports during the university period. Three cross-sectional surveys were conducted in the years 2010, 2012 and 2014, with students from a higher education institution. The dependent variable was the current practice of team sports and the independent variable the participation, prior to entering the university in Physical Education classes at school. Participated 1,084, 1,085 and 1,041 college in 2010, 2012 and 2014, respectively. The proportion of practicing team sports was stable in the three surveys and college who participated regularly of the lessons of Physical Education, prior to entering the university showed higher prevalence ratios (PR) practice of team sports during college years (2010, RP: 2.87; 95%CI: 1.48; 5.55; 2012, RP: 2.04; 95%CI: 1.14; 3.65; 2014, RP: 4.06; 95%CI: 1.58; 10.43). The number of students practicing team sports was similar in all investigated years and regular participation of college in Physical Education classes in school, period prior to entering university showed a positive association with practice of team sports at the university.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p233 In the past few years, increased popularity of resistance training (RT) and a significant increase in the number of professionals and undergraduate in Physical Education students have been observed. A variety of names has been usually adopted for the same resistance exercise in fields. The aim of the study was to compare the resistance exercise nomenclature adopted by physical education professionals and students, and also to identify the frequencies of names adopted for these resistance exercises. The study included 191 graduate students and active physical education professionals of RT centers and gyms in the state of Rio de Janeiro, Brazil. Ten exercises traditionally performed on RT programs were selected. The results indicated that there was no association between the nomenclature of exercises and academic degree for all exercises included in the survey. However, there was significant difference (p <0.001) among response frequencies for each exercise, for the whole sample. In this sense, this study enabled identifying significant differences in the nomenclature of resistance exercises. Therefore, nomenclature standardization is essential to establish a direction and clearness in communication among professionals.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p259 Obesity is considered a disease with multiple etiologies. Recent advances in technology have pointed candidate genes that are related to weight gain in several populations. However, in countries with ethnic miscegenation, such as Brazil, studies of this nature with students are still scarce. The aim of the present study was to compare anthropometric variables of Brazilian male students according to the genotypes of the rs9939609 of the FTO gene. In order to do so, 205 participants underwent body mass, height, waist circumference and skinfold thickness measurements. Body mass index (BMI), waist-to-height ratio and body fat percentage were calculated. Volunteers were characterized as overweight according to the BMI-for-age z-score. Participants were genotyped according to the single nucleotide polymorphism rs9939609 of the FTO gene (AA, AT and TT). ANOVA one-way with Bonferroni’s post hoc was performed to compare genotypes and anthropometric variables. Odds Ratio was calculated to reveal increased chances of presenting higher body mass index z-score, waist-to-height ratio and body fat percentage. Participants homozygous for the A allele presented significantly higher values of BMI-for-age z-score (0.38±1.01 vs. -0.29±1.15), waist circumference (77.15±6.51 vs. 72.85±7.36 cm) and waist-to-height ratio (0.44±0.04 vs. 0.42±0.04) when compared to individuals with the TT genotype. The A allele of the rs9939609 of the FTO gene seems to influence in the adiposity of male students.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p277 This study aimed to estimate the prevalence of overweight and investigate its association with sociodemographic factors, physical activity level, hypercholesterolemia, and diabetes in civil servants of a university in the state of Paraná, Brazil. The research was conducted with 339 civil servants aged above 18 years. Overweight was analyzed by self-reported body mass index. Physical activity level was evaluated using a questionnaire. Sociodemographic data (sex, age, economic status, educational level, marital status, and working hours) and information on the chronic diseases of interest (hypercholesterolemia and diabetes) were obtained from self-report. The association between overweight and the other variables was investigated using binary logistic regression. The prevalence of overweight was 50.6%. The groups most susceptible to overweight were: male civil servants (OR: 2.04; CI: 1.30-3.22), those less than 12 years of education (OR: 2.46; CI: 1.43-4.23), who were insufficiently active (OR: 1.64; CI: 1.03-2.60), and those with hypercholesterolemia (OR: 2.28; CI: 1.32-3.96). This study concluded that more than a half of the sample was overweight and that this condition was associated with male sex, educational level below 12 years, insufficient physical activity, and hypercholesterolemia.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p287 The aim of this study was to examine the reliability of the 6-minute walk test (6MWT) and post-exercise cardiac autonomic markers in physically active and sedentary older women. Eighteen physically active older women (64.2±3.1 years; 63.0±2.7 kg; 1.52±0.06 m; 26.9±2.7 kg.m-2) who performed Tai Chi Chuan for at least 6 months, and 18 sedentary older women (64.0±3.7 years; 63.8±8.9 kg; 1.49±0.05 m; 28.4±3.5 kg.m-2) were submitted to 6MWT in two separate occasions. Immediately after 6MWT, heart rate recovery at one (HRR1’) and two minutes (HRR2’), as well as the heart rate variability (HRV) were recoded. Reliability was verified by intraclass correlation coefficient (ICC) with 95% confidence interval, Bland-Altman plots were used as a measure of agreement, and coefficient of variation (CV) was calculated. High reliability (ICC=0.86) was found for performance in 6MWT (528.8 ± 71.4 m and 473.2 ± 62.4 m; CV=7.9 and VC=8.5%) in both groups. Likewise, high reliability (ICC≥0.84 and ICC≥0.80) was found for HRR 1’ (29.0±11.0 bpm and 17.0±8.0 bpm; VC=30.1% and VC =40.2%) and HRR 2’ (36.0±10.0 bpm and 24.0±9.0 bpm; VC =23.7% and VC =22.8%) in both groups. Regarding HRV, moderate reliability was found in the active group (CCI≥0.57; VC =35-47%), while moderate-high reliability was found in the sedentary group (CCI=0.65-0.76; VC=34-69%). Agreement was found for all variables analyzed. In conclusion, post-exercise 6MWT, HRR, and HRV are reliable tools to assess functional capacity and cardiac autonomic control in physically active and sedentary older women.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p311 The aim of this study was to compare coordination index, propulsive time, duration of stroke phases and kinematic parameters over 200 m front crawl. Variables were compared among four sections of 50 m (T1 to T4) in fifteen competitive swimmers (age: 21.1 ± 7.1 years; height: 180.1 ± 6.1 cm; height: 187.3 ± 8, 1 cm; body mass: 72.1 ± 10.1 kg; better performance in the race: 77.5 ± 4.7% of the world record). Data were obtained with two video cameras (60 Hz - coupled to a cart on rails on the side of the pool) for simultaneous images of the swimmer’s sagittal plan: below the water line and above the water line. Mean stroke rate stroke length, assumed as the mean distance traveled per cycle, and mean swimming speed were obtained with manual timing. Over the 200 m, the coordination index remained unchanged (p >0.05), but there was an increase in the frequency of cycles (p <0.05) and reduction of distance traveled per cycle (p <0.05). Between T1 and T2, there was an increase in the propulsive time (p <0.05) and between T1 and T4, there was an increase in the length of the pull phase (p <0.05). The swimming speed decreased only between T1 and T2 (p <0.05). Over 200 m front crawl, well-trained swimmers increment propulsive time and pull phase duration and frequency of stroke cycles, and such changes may be due to the speed maintenance attempt over the 200 m.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p322 The purpose of the present investigation was to identify the effects of a 130-km cycling race on indices of biochemical indirect markers of muscle damage and muscle soreness responses during a 72-hour recovery period. Fifteen endurance-trained male cyclists which were competing for more than 2 years and were involved in systematic training at least of 3 days/wk underwent a collection of indirect biochemical markers of muscle damage (CK, LDH, Myo) and delayed onset of muscle soreness (DOMS), at five different moments of data collection: before (PRE) and immediately after (POST) a 130-km cycling race, and 24, 48, 72 hours following the cycling race. CK and LDH plasma concentrations significantly increased POST-race (p < 0.001) and remained high throughout the 72 hour recover period (CK: p < 0.05; LDH: p < 0.001). Myo increased significantly POST-race (p < 0.001) and returned to the PRE-race values 24 hours thereafter (p < 0.05). DOMS increased significantly POST-race (p < 0.001) and returned to the PRE-race values at 48 hours after (p > 0.05). A 130-km cycling race has a noteworty effect on indices of biochemical indirect markers of muscle damage and muscle soreness responses, indicating that 72 hour recovery period do not seems to be enough for long-distance cyclist, and reinforce the propositions of scientific literature about the need of a sufficient recovery period for cycling endurance athletes.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p332 Physiological effects of thermal changes in tissues might influence some physical properties of muscle fibers, such as strength. The aim of this study was to compare the effects of cryotherapy and microwave diathermy application on the strength production capacity of the elbow flexor muscles. Thirty male, healthy and sedentary subjects, with average age of 22.40 (±3.42) years, participated in this prospective study. Participants were submitted to assessment of isometric strength production capability by an adapted load cell. Half of volunteers received cryotherapy on the first day of application and microwave diathermy (MD) 48 hours later, whereas the other half was treated the other way around. Cryotherapy was applied up to the temperature of the biceps region reached 25ºC, and MD was applied up to 42ºC. Six peak strength reevaluations were made over 2 hours. There was significant increase in peak strength (PS) up to 15 minutes after cryotherapy, then there was a decrease in maximum isometric strength, however, statistically significant difference remained up to 1 hour and 30 minutes after cryotherapy. In MD, PS decreased significantly after application until 15 min. From this moment, PS returned close to the initial value, and in the last assessment, PS reduced again. Cryotherapy and MD differently interfered in isometric muscle strength production capacity of elbow flexors, while cooling generated increment, heating caused decline.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p362 The aim of this study was to verify the influence of the technical skills level on the decision making of novice volleyball players on service, reception and set actions. The sample was composed of 80 novice athletes of school volleyball teams of both sexes. Based on the results from the Volleyball Skills Test Battery, the sample was divided into three groups: low, intermediate and high technical level, by means of One-Way ANOVA. The intermediate group was excluded from further analyses. Decision making was assessed with the Game Performance Assessment Instrument (GPAI). For data analysis purposes, the independent student-t test was used, adopting significance level of p≤0.05. The results showed that players with low skill level in service and set actions also had lower performance on the decision-making test when compared to players with high technical level. On the other hand, in the reception action, no differences were found among groups. It was therefore concluded that the technical level seems to influence the decision making in service and set actions in novice volleyball players.

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 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.

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.
