title: Skeletal age and explosive strength in young volleyball players

description: Abstract Identifying different anthropometric, physiological and motor aspects is essential to obtain success in sports practice. However, these components may be developed in same age subjects differently, in part due biological development. The aim of the study was compare and correlate the explosive strength to biological maturation by sex, obtained by estimation of skeletal age based on anthropometric variables. The sample consisted of 239 subjects of both sexes, aged 10 to 13 years. Maturation was assessed by skeletal age predictive equation and upper and lower limbs explosive strength using medicine ball throw test and vertical jump, respectively. Skeletal age was assessed by skeletal age using a predictive anthropometrical based equation. Upper and lower limbs explosive strength were evaluated by medicine ball throwing test and vertical jump test, respectively. Post hoc analysis showed delayed biological development subjects had worst medicine ball throwing test performance than accelerated boys (p=0.001; d=0.96) and girls (p&lt; 0.01; d= 2.01); regarding to vertical jump test, worst performance was also detected to maturational delayed boys when compared to accelerated ones (p=0.24; d=1.1) and girls (p=0.007; d=0.75). Regression analysis showed skeletal age explained variance of 36% and 19.2% for boys and 45.2% and 16.1% for girls upper and lower limbs explosive strength. Skeletal age is positively related to upper and lower limbs explosive strength and show higher performance for accelerated biological development young players when compared to delayed ones, independently from sex.

title: Reliability of isometric and isokinetic peak torque of elbow flexors and elbow extensors muscles in trained swimmers

description: Abstract In this study, it was hypothesized that the peak torque reliability would depend on the type of muscular action. The aim of this study was to analyze and to compare the reliability of isometric peak torque (IPT) and isokinetic peak torque at speeds of 60º.s-1 and 180º.s-1 (CPT60 and CPT180, respectively) of elbow flexors (EF) and elbow extensors (EE) muscles in trained swimmers. Twenty trained male swimmers (23 ± 5 years) performed the following protocols in different days: 1) Familiarization to isokinetic dynamometer; 2) Two maximal isometric voluntary contractions to determine IPT and five maximal concentric isokinetic contractions at 60º.s-1and 180º.s-1 to determine CPT60 and CPT180, respectively (T1). The tests for IPT, CPT60 and CPT180 determination were performed in random order, and; 3) The same tests were performed in the same order of those performed on the second day (T2). There was no significant difference of IPT, CPT60 and CPT180 values between T1 and T2. Higher intraclass correlation coefficient (ICC) and lower typical error (TE) of IPT (ICC - 0.87 - 0.92; TE - 6.9 - 10.9%) in relation to CPT60 (CCI - 0.66 - 0.79, TE - 12.0 - 12.8%) and CPT180 (ICC - 0.85 - 0.85; TE - 8.5 - 9.2%) was observed. Based on these results, it could be concluded that the peak torque of EF and EE muscles presents moderate to excellent reliability, and can be influenced by the type of muscular action performed by trained swimmers.

title: Cross-cultural adaptation and psychometric properties of the Brazilian coach-athlete relationship questionnaire (CART-Q) - Athlete Version

description: Abstract The aim of this study was to test the psychometric properties of the Brazilian version of the Coach-Athlete Relationship Questionnaire (CART-Q) - Athlete Version. For this, three studies were performed. In the first, four translators and five experts in Sport Psychology adapted the CART-Q contents to the Brazilian context. In the second, 364 athletes of individual and collective sports answered the adapted version of CART-Q. In the third, an independent sample of 185 athletes answered the CART-Q and the Task and Ego Orientation in Sport Questionnaire (TEOSQ) to analyze the external validity of the instrument; and 50 athletes answered the CART-Q in two distinct moments for the analysis of the temporal stability. Study 1 showed that the Portuguese version contains clear and relevant questions (CVC&gt; 0.80). Study 2 showed that the CART-Q presents satisfactory internal consistency (α&gt; 0.70 / CC&gt; 0.70). The confirmatory factor analysis showed that the model with 11 items showed good fit [X2/gl = 3.03; CFI = 0.96, GFI = 0.94; TLI = 0.94; RMSEA = 0.08] and also the existence of the second-order model. Study 3 showed the external (r&gt; 0.40 with variable task orientation) and internal validity (CFA with an independent sample) and temporal stability (ICC&gt; 0.70). It was concluded that the Brazilian version for of CART-Q proved to be valid to evaluate the perception of athletes about their relationship with the coach in the Brazilian sports context.

title: Exposure to simultaneous sedentary behavior domains and sociodemographic factorsassociated in public servants

description: Abstract Exposure to sedentary behavior may contribute to health problems. This study aimed to estimate the prevalence of exposure to simultaneous sedentary behavior domains and verify associated sociodemographic characteristics among technical and administrative servers of a Brazilian university. This is a cross-sectional epidemiological study carried out with 623 technical and administrative servers. Sedentary behavior was identified through a questionnaire in the following domains: commuting (active / passive), sitting time at work, daily time spent watching television and computer use (≥3 hours / day). Sociodemographic variables were age, sex and educational level. The prevalence of servers that had one, two, three and four simultaneous sedentary behavior was 28.4%, 43.2%, 22.5% and 4.3%, respectively. Women were more likely to have three sedentary behavior simultaneously (OR = 1.61, CI 95% = 1.02, 2.56). Servers with 9-11 years of schooling were less exposed to two (OR = 0.27, CI 95% = 0.17, 0.44), three (OR = 0.39, CI 95% = 0.23, 0.66) and four (OR = 0.22, CI 95% = 0.07; 0.69) sedentary behavior simultaneously and those over 12 years of schooling were less likely of having two (OR = 0.22, CI 95% = 0.10; 0.49) and three (OR = 0.15, CI 95% = 0.05, 0.46) sedentary behavior simultaneously. More than half of servers have two sedentary behavior during the week. Having sedentary behavior in more than one domain simultaneously was associated with sex and educational level.

title: Effects of downhill walking training on aerobic and neuromuscular fitness of young adults

description: Abstract Eccentric exercise training using low intensity-high volume approach has been performed to improve maximal muscle strength and power. The aim of this study was to compare the effects of short-term downhill walking and level walking training on lower limb strength and maximal oxygen uptake of active individuals. Eighteen young adults were divided into level walking group (n = 9) or downhill walking training group (n = 9). Both groups performed a four-week training program. The level walking group performed seven level walking sessions per week, while the downhill walking group walked downhill (-16%) in the same weekly frequency. One week before and one week after the training protocol, maximal oxygen uptake, muscle-bone cross-sectional area and isometric peak torque of knee extensors and plantar flexors were assessed for both groups. A significant group vs. time interaction was found only for cross sectional area of plantar flexors (PF), showing increases for the downhill walking group (112.6 ± 28.9 cm2 vs. 115.9 ± 29 cm2) but not for the level walking group (94.9 ± 23.3 cm2vs. 94.6 ± 228 cm2). Maximal oxygen uptake remained unaltered after training for both groups and IPT was increased after training for both groups. It was concluded that short-term downhill walking training does not seem to be efficient in promoting improvements in cardiorrespiratory fitness of young adults. However, it seems to promote gains in some variables related to neuromuscular fitness.

title: Ballistic stretch or aerobic warm-up evoke postexercise hypotension after maximal exercise

description: Abstract Warm-up is broadly used to increase performance and protect against injury in sports. However, the effects of different models of warm-up on maximal exercise and the subsequent recovery period are undetermined. This study aimed to assess the effects of different warm-ups on performance, blood pressure and autonomic control. Methods: 53 subjects rested for 5 minutes and then were randomly allocated to one of four experimental groups: Control (CTR), Aerobic Warm-up (AER), Static (SST) or Ballistic (BST) stretch. Immediately after warm-up, they performed a maximal cycling test and rested for 30 minutes. Heart rate variability (HRV), Systolic (SBP) and diastolic (DBP) blood pressure were assessed throughout the entire experiment. Statistical analysis was performed by one-way ANOVA with Tukey post-test or two-way ANOVA followed by either Bonferroni or Dunnet post-test, when appropriate. Warm-up did not change test performance or HRV (p&gt;.05), however, when compared between-groups, SBP was higher in BST against all groups (p.05). When compared to baseline values SST showed increased SBP in recovery (p

title: Relative age effect in Brazilian Basketball Championship: Under 15 players

description: Abstract In sport, the relative age effect (RAE) refers to the advantages of participation and performance that athletes born in the first months of the selection year have in relation to those within the same age category. The aim of the present study was to investigate the RAE in athletes of the Brazilian Basketball Championship of the U-15 category in 2015, analyzing differences between sexes, geographic region, competitive level and performance of teams. The information of teams and the birth quarter (quartile) of 530 basketball players were obtained through the website of the Brazilian Basketball Confederation (www.cbb.com.br). The results showed greater representation of male athletes born in the first months of the year, the first and second divisions, of the Southeastern, Northern and Mid-Western regions and in female medalists. It was concluded that the RAE is present in Brazilian U-15 male basketball players, being higher in athletes of higher competitive level, particularly in the Southeastern, Northern and Mid-Western regions of Brazil. In addition, RAE proved to be associated with the winning of women’s medals.

title: Association between Physical Education program in school and the practice team sports during university

description: Abstract The practice of team sports such as soccer and volleyball, are one of the main activities practiced by college. 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.
