title: Reasons for dropout of the practice of artistic gymnastics in the extracurricular context

description: Abstract Sport is the main option for physical activity among children and youth. Despite the great interest of this group with regard to sports practices, the literature indicates a high dropout rate. Motivated by this conjuncture, the objective of this study was to verify the reason for dropout, more specifically, in Women Artistic Gymnastics (WAG) within the context of extracurricular activities. We interviewed practitioners of WAG who have a record regarding withdraw of this sport for a certain period of time. For the data treatment, the content analysis proposed by BARDIN was chosen. We found that intrinsic and extrinsic factors are linked to the process of dropout of this sport. However, the extrinsic factors overlapped those intrinsic, evidencing that the environment and situational and interpersonal conditions exert greater influence on the withdrawing of the gymnasts. Thus, we emphasize the importance of the coaches’ attention to these aspects in order to ensure that activities meet the needs and desires of gymnasts.

title: Effects of the alternance between aerobic and resistance exercise in different concurrent exercise sessions on blood pressure responses of healthy adults: a controlled and randomized study

description: Abstract Aerobic exercise (AE) and resistance exercise (RE) have shown benefits in preventing and / or controlling blood pressure (BP), although the influences of these two models (concurrent exercise) in a single session of exercise on BP are still unknown to the individual. Therefore, the aim of the present study was to verify the effects of the alternating between AE and RE in different concurrent exercise sessions on BP responses. In order to do so, ten young male athletes (22.6 ± 3.78 years, 70.3 ± 5.89 kg, 175.96 ± 5.83 cm, 6.8 ± 2.38 % body fat) participated in the study. The tests consisted of four randomized protocols, the sessions consisted of AE followed by RE (AR), RE followed by AE (RA), circuit (CC) (ER and EA alternating intermittently) and control session (CO) (without exercise). AE was performed on a treadmill at 90% of indirect minimum lactate and RE was performed on a circuit at 90% of 12 RM, alternating muscle segments in six exercises. BP was measured in all protocols and post-exercise recovery period (PERP) every 15 minutes during one hour. Results showed a significant decrease in systolic blood pressure (SBP) at the 45th minute of recovery (R45) and one-hour mean values of the PERP in the RA protocol when compared to its value at rest. Diastolic and mean BP showed no significant differences. Thus, the RA session promoted a more accentuated decrease in SBP when compared to the other sessions.

title: Multilevel modeling and mixed longitudinal design in the research in Physical Education and Sport Medicine

description: The main aim of this study was to introduce the use of multilevel modeling in the data from a mixed longitudinal study concerning growth, development and health of Portuguese adolescents. The sample comprises 5155 subjects from 4 age cohorts: 10 to 12, 12 to 14, 14 to 16 and 16 to 18 years. Variables chosen for analysis were handgrip strength and percentage of total body fat. Multilevel modeling analysis showed a quadratic trajectory of adolescents' handgrip strength performance, with higher annual increasing in boys. The percentage of total body fat was positively associated with the static strength and there were marked interindividual differences. The use of a mixed longitudinal design allowed a faster data collection process; in addition, multilevel modeling analysis was sufficiently flexible and robust to accommodate, in a single model, aspects of individual and interindividual changes in static strength development over the time.

title: Attitudes towards physical exercise and body image dissatisfaction of individuals who frequently go to gyms

description: AbstractThe aim of this study is to evaluate the body image dissatisfaction, and negative attitudes towards physical exercise, and the correlation among these two factors in individuals who frequently go to gyms. A sample of 100 sportspeople (67 women and 33 men) has answered electronically the Body Shape Questionnaire (BSQ) and Commitment Exercise Scale (CES). Participants also informed weight, height, time spent at the gym and their objectives in exercising. Pearson´s correlation analysis between BSQ and CES were evaluated, and CES scores were compared to BSQ classifications using Student's t-test. Differences between genders were evaluated using generalized linear model. Linear regression model tested predictors for body satisfaction and attitudes towards exercise. It was found that women have a higher level of body image dissatisfaction (p &lt; 0,001). Moreover, there was not any difference between sex in relation to physical exercises. There was not found any correlation between body image dissatisfaction and the attitudes towards physical exercises, however, there was a positive correlation between Body Mass Index (BMI) and body image dissatisfaction (p = 0,001 to men; p = 0,002 to women). The time spent at the gym was predictor to negative attitudes towards physical exercises (R2 = 0,580), and the BMI and a smaller importance of leisure in the practice of physical exercise were predictors of body insatisfaction (R2 = 0,368). Similar studies evaluating other body image aspects, such as drive for muscularity are needed.

title: Ball velocity on the kick in futsal: comparison between youth with different performance levels and correlation of the predictive variables of performance

description: AbstractThe aim of this study was to compare and verify the possible correlations between ball velocity with foot velocity, knee angle and length of last stride between practitioners and non-practitioners of futsal game. Fourteen young males with aged between 13 and 15 years old divided into two groups: practitioners (G1) and non-practitioners (G2), according with the time of futsal structured practice. For the kinematic analysis we had used two cameras at a sampling frequency of 120 Hz, fixed laterally to the movement performed in order to focus the markers in the limb of kick. Each participant has performed ten kicks simulating a kick of ten meters in futsal. Three-dimensional data of the lower limb of kick were obtained in DVIDEOW software and treated in Matlab environment in order to obtain the variables of interest: ball velocity (VELBALL), foot velocity (VELFOOT), knee angle (ANGKNEE) and length of last stride (LLS). Statistically all data displayed higher levels in G1 compared to G2. In addition, no significant differences were found between trials in each group (p &lt; 0.05). In G1 a multiple regression analysis revealed only influence on VELBALL 17% caused by LLS. Moreover, in G2 any variable have influenced VELBALL. However, we conclude that the variables are different between practitioners and non-practitioners of futsal game with aged between 13 and 15 years old, and the variable VELBALL could be little influenced by the LLS in this age band. Thus, we suggested that coaches maintain focus on development and monitoring this characteristic of movement, especially in novices, in order to identify players with different levels of performance of kicking in a futsal context.

title: Network design of a social sports project: actors, representations and meanings

description: This study is offered with the aim of exploring the meanings assigned by a network of actors who develops a social sports project. The Boxing Project Vidigal (PBV) has its activities in the Vidigal slum, located in the south of the city of Rio de Janeiro, next to the neighborhood of Leblon. The methodology used in this study was based on the procedures of network analysis and also the construction of categories, based on the definition of the core and the periphery of representations. We conclude that there is great centralization of the person who conceived the project, for this reason there is low density and high centrality in the network. The perceptions of the actors roam the ideas that the project "changes people's lives," that young people "become less aggressive," that there are "social contribution in the formation of children, youth and families" and promotes "social inclusion of people living in poor.

title: Analysis of the offensive patterns of the Spanish National Soccer Team in the 2010 FIFA® World Cup, in relation to match status

description: This paper aimed to analyze the tactical behavior of Spain National Football Team during the FIFA(r) World Cup, in four different match statuses: Draw, Win+1, Win+2, and Loss-1. The sample comprised 894 offensive sequences performed over Spain's seven matches during the tournament. Data analysis was performed through observations of video footage recorded from a TV station. Following variables were analyzed of play: Achievement time of the attack, Number of contacts with the ball, Number of balls received/Number of passes, Ball transmission speed, Location of acquisition and recovery of ball possession and Form of acquisition and recovery of ball possession. Descriptive statistics were conducted, and so were Chi-Square and Kruskal-Wallis tests. The significance level was set to p &lt; 0.05. Significant differences were found for the following variables: "ball transmission speed", "location and form of acquisition and recovery of ball possession". In conclusion, it was possible to infer that the tactical behavior of the Spanish team underwent few modifications during the tournament regarding match status.

title: Effect of β-alanine supplementation on 20 km cycling time trial performance

description: The effects of β-alanine supplementation on high-intensity cycling performance and capacity have been evaluated, although the effects on longer duration cycling performance are unclear. Nineteen UK category 1 male cyclists completed four 20 km cycling time trials, two before and two after supplementation with either 6.4 g•d-1 β-alanine (n = 10; BA) or a matched placebo (n = 9; P). Performance time for the 20 km time trial and 1 km split times were recorded. There was no significant effect of β-alanine supplementation on 20 km time trial performance (BA-pre 1943 ± 129 s; BA-post 1950 ± 147 s; P-pre 1989 ± 106 s; P-post 1986 ± 115 s) or on the performance of each 1 km split. The effect of β-alanine on 20 km time trial performance was deemed unclear as determined by magnitude based inferences. Supplementation with 6.4 g•d-1 of β-alanine for 4 weeks did not affect 20 km cycling time trial performance in well trained male cyclists.

title: Hazard score, rating of perceived exertion and pacing strategy during a 10 km running

description: The aim of the study was to verify the modifications on pacing strategy induced by the hazard score of premature fatigue and rated perceived exertion (RPE) in amateur runners during a simulated 10-km running. Fifty five amateur runners with the 10-km run time of 41:39 ± 3:52 min:s participated in the study. The pacing strategy and the RPE were analyzed each kilometer. The hazard score of premature fatigue was expressed as the product of RPE by the remaining distance of the running. An ANOVA one-way for repeated measures was applied to determine possible statistical differences in speed, RPE and hazard score at each kilometer or the running speed differences at each kilometer and the average running speed. Pearson's product moment correlations were calculated between RPE and hazard of premature fatigue and running speed. The speed in the first kilometer was 8.1% higher than the average speed (p ≤ 0.001). There was a progressive decrease in speed during the running with an increment near the last kilometer. The RPE increased linearly until the end of the running and the hazard score of premature fatigue significantly decreased after the third kilometer. During the running there was a strong negative correlation between speed and RPE (r = -0.80; p = 0.006). It was also observed a moderate negative correlation between speed and hazard score of premature fatigue (r = -0.57; p = 0.04). Thus, our results suggested the important role of RPE on speed adjustment during a 10-km running and the increase of running speed near the end of the race seems to be associated to the lower score of hazard of premature fatigue.

title: Visuomotor memory in elderly: effect of a physical exercise program

description: Memory, namely visuomotor memory, is one of the most essential cognitive functions in elder’s life. Among others, regular exercise seems to be an important factor in counteracting age-related-cognitive skills changes and thus prevent memory loss. However, in spite of the importance of visuomotor memory, the results of the scarce studies concerning the influence of exercise on this capacity are contradictory. The aim of this study was to investigate the effect of physical exercise (PE) in visuomotor memory (VMM) of elderly adults in function of gender and age. VMM (time spent in performing the test and errors during the execution) of 74 subjects aged 60-90 years, being 36 practitioners of PE (P - mean age of 70.22 ± 0.90 years) and 38 non-practitioners (NP - mean age of 68.26 ± 1.12 years) were assessed by VMM Test. The results showed that: a) P presented a better performance in the time of performing the test and in the number of errors committed compared to NP; b) Gender and age did not influence the VMM performance. Data suggest that PE seems to have positive effect in the VMM, independently of gender and age.

title: Wellness of physical education teacher of southern region of Brazil according to the life cycles

description: The aim of the study was to evaluate association between the life cycles and the social-environmental (work satisfaction) and individual (lifestyle) parameters of Wellness in Physical Education Teacher from the public teaching southern region of Brazil. In the investigation, 1645 teachers answered a social-demographic and professional questionnaire, as well as the QVT-PEF and PEVI tools. The chi-square, likelihood ratio and multinomial logistic regression, in the original form and in two adjusted models, were used for evaluating the associations. The results demonstrated that the use of moderating variables in the adjusted analyses of work satisfaction construct helped in understanding the teachers's perceptions changes across the life. Contrary situation was demonstrated in lifestyle evaluation, which revealed that the original model analysis was the principal manner of observing significant differences in most of the components and in the general computation.

title: Comparison of a single leg stance balance between children and adults

description: The aim of this study was to compare postural balance in single leg stance between typically developing children aged 8 to 11 years old and healthy adults. The participants were divided into 3 groups: 8-9 years old, 10-11 years old and 18-30 years old. A force plate (AccuSway Plus, AMTI, Inc.) was used to measure the postural balance. Each subject performed three trials lasting 30 seconds in dominant single leg stance. The parameters recorded were: center of pressure amplitude the in the anteroposterior and mediolateral directions, total path length, average velocity and 95% of the ellipse area. SPSS (version 13.0) was used for statistical analysis. Shapiro-Wilk test, One-way Anova, Bonferroni post hoc and Pearson correlation were applied. The level of significance used was p &lt; 0.05. The results showed significant differences (p &lt; 0.01), between children and adult groups in all variables. Between groups of children (8-9 years and 10-11 years) there was no significant difference in any variables. The results suggest that children aged 08-11 years old have not reached complete maturation of postural balance. This information may be important to aid in the diagnosis of disorders or deficits of balance, both in children and in adults.

title: In vitro and in vivo study of Williams-type periodontal probes available in the Brazilian market

description: Abstract Introduction The periodontal probe is the best tool for the clinical diagnosis of periodontal disease; however the probe design can influence the results. Objective To evaluate the structural characteristics of Williams-type periodontal probes available in the Brazilian market and evaluate their clinical use during periodontal probing. Material and method The probe groups were divided into: 1) Hu-Friedy® (n=15); 2) Trinity® (n=15); 3) Fava® (n=15); 4) Millennium® (n=15). In vitro analyzes were performed: weight (g), diameter of the active tip (mm), cable diameter (mm) and millimeter of the probes (mm). For the in vivo study, 10 participants were selected who had at least four teeth with periodontitis. The probe marks were coded in A, B, C and D for the examiner's blinding. Result There was a diameter of the active tip suggestive of a conical three-dimensional shape for the Trinity®, Hu-Friedy® and Millennium®, with increasing taper, while the Fava® tip demonstrated a suggestive diameter of a cylindrical / parallel three-dimensional shape. The Fava® probe showed the largest diameters in the initial and middle thirds, while the Hu-Friedy® revealed the smallest diameter in the initial third. All the probes presented similar milimeter. In the clinical study, it was found that the Fava® probe resulted in a lower average of probing depth than the others. Conclusion Periodontal probes have structural differences that must be considered during the selection of the instrument, and the conical probes present more reliable results to clinical practice, since the design of the probe directly interferes with the clinical diagnosis of periodontal disease.

title: Influence of metal bar lever-arm on screws detorque for dental prosthesis implant supported

description: Abstract Introduction The cantilever length of implant-supported fixed prosthesis metal structure has been considered an important factor to transfer occlusion forces to the dental implant. Objective This study evaluated the influence of different extensions of cantilevers of Branemark protocol implant prosthesis when submitted to mechanical thermocycling by screw loosening evaluation. Material and method The groups G10 (n = 5), G15 (n = 5) and G20 (n = 5) were formed according to the distance in millimeters between the force application site in the cantilever and the center of the last implant. All metal structures (n = 15) were submitted to a 120 N cyclic vertical load in a chewing simulation machine (MSM-Elquip, São Carlos-SP, Brazil) under controlled temperature and moisture conditions. Two hundred and fifty thousand mechanical cycles were performed with a frequency of 2 Hz that simulates a masticatory activity similar to 3 months. To compare the data obtained regarding the loosening of the metal structure screws, implant position and sites of load application, the analysis of variance with two factors and the Tukey test were performed. Result Statistical analysis showed that the G10 group presented greater torque loss, statistically different from G15 (p = 0.001) and G20 (p = 0.002), and there was no significant difference between groups G15 and G20. Conclusion It can be concluded from the results that all the screws presented torque loss after simulation of 3 month masticatory activity, suggesting the need for periodical evaluation to prevent failures in the treatment.

title: Behavioral and clinical aspects associated with probable sleep bruxism in early childhood

description: Abstract Introduction Although many studies are being carried out with sleep bruxism, the literature points to a lack of studies with methodological quality in children. Objective To evaluate the behavioral and clinical aspects associated with probable sleep bruxism in early childhood. Material and method A cross-sectional observational study carried out with 371 children between 4 and 6 years of age. Parents answered a questionnaire with aspects related to their children's sleep behavior. Among the clinical characteristics, the presence of lip sealing, clicking, teeth marks on the jugal mucosa, and the side of the tongue was evaluated. Tooth wear was assessed using the BEWE index criteria. Simple logistic regression models were adjusted for each independent variable, estimating the gross odds ratios with the respective 95% confidence intervals. Variables with P &lt;0.20 in the individual analyzes were adjusted in a multiple logistic regression model, with those with P ≤ 0.05 remaining in the model. Result 42.4% of parents reported that their children gritted their teeth while sleeping. Children who showed wear on their teeth were 1.53 times more likely to grind their teeth. There was no significant association with the other variables analyzed (P &gt; 0.05). Conclusion Behavioral aspects were not associated with probable sleep bruxism. Among the clinical characteristics evaluated, tooth wear showed an association, which may indicate the probable bruxism of sleep in early childhood.

title: External control of water fluoridation in a small municipality of northeast of Brazil

description: Abstract Introduction Fluoridation of public water supply is an important measure in the prevention of dental caries. Objective This study aimed to monitor the fluoride (F) concentrations of a public water supply with water fluoridation program in a small municipality in the Northeast region of Brazil. Material and method It is a quantitative study with a descriptive approach. Three points of the urban area were selected for collecting water samples twice a month for 12 months. The average of F concentrations was calculated considering these three samples of each collection point at the same occasion. F concentrations in the water samples were determined by potentiometry and the results were classified according to the criterion proposed by criterion set down by Collaborating Center of the Brazilian Ministry of Health for Oral Health Surveillance. The samples were classified according to the best risk-benefit adjustment (0.55 – 0.84 mg F /L). Result Less than 10% of the samples were within the ideal range. Conclusion It was observed that water fluoridation in this municipality was interrupted since many water samples showed f-levels below the minimal acceptable values.
