title: Sociocultural domain

description: It was intended to examine the contextual influences and socio-environmental attitudes and behaviors of young athletes in sport participation. The participants were 24 young soccer players in a Professional Oriented Club (POC), divided into four teams, sub 14 through sub 17; they participated in group interviews regarding their sport participation, characterization of the context of practice and interpersonal relationships. The group climate, among peers, was positively mentioned by young athletes’ as important. The search for status and recognition, alongside with the aspiration to professionalism were stated as important in their sport trajectories. Parents are important agents in sport participation. The relationship with the young coach proved to be influential in the motivational climate perceived by young people. The results determine important assets to take into consideration when construing the training structure in youngsters playing in professional clubs. Young athletes’ sport participation needs to take into account the context of practice to promote positive development.

title: Stages of behavior change for physical activity among college students and associated sociodemographic factors

description: The objectives of this study were to describe the Stages of Behavior Change (SBC) for Physical Activity (PA) and to identify sociodemographic factors associated with SBC for PA among Physical Education students from a public institution in southern Brazil. This is a cross-sectional study with 236 Physical Education students from the Federal University of Santa Catarina. SBC (pre-contemplation, contemplation, preparation, action and maintenance) was assessed through a questionnaire. The following sociodemographic variables were analyzed: sex, age, marital status, employment, income, university course and maternal and paternal education. Among students investigated, 18.6% were in stages of physically inactive behavior (0.4 % pre-contemplation, 2.5 % contemplation, 15.7 % preparation). In relation to stages of active behavior, 81.4 % of college students were in the following situation: 18.2 % action; 63.2 % maintenance. Women were more likely to show inactive behavior. Health education programs and encouragement for the practice of sports in universities should be adopted to modify and adopt active behavior.

title: Football: representations and practices of students of the elementary school

description: This study aimed to characterize the practices and social representations of students about football within the Physical Education classes. This is a qualitative research of ethnographic type, which used participant observation and semi-structured interviews, as well as questionnaires, in a class of 29 students from 6th grade of Elementary Education, in a private school in Bauru City-SP. The results indicate that the media and the family are the main elements that constitute the representations of students about football, and that the way football practice is developed at school simultaneously builds and feed them. We conclude that social representations rule the relationships of students with football, insofar as they guide and organize their behavior. However, this does not make their conduct and values homogenous, because the students seek in football the satisfaction of something that is also personal, as fun and friendship.

title: Development of professional volleyball players: relations between elite athletes and early specialization

description: Although the literature indicates harms of early sport specialization, this procedure remains applicant, based on the belief that sooner training and participation in competition increase the chance of success in highest level. The purpose of this study was to investigate how was the process of sports initiation of 52 male professional volleyball players, in the Paulista Championship and National Superligue. The focus was to analyze the possible occurrence of early specialization and diverse sporting experiences. Data was collected using a questionnaire and analyzed by descriptive statistics. Results show that the majority of the athletes were not early specialized and experienced different practices during training in childhood in different sports. The data support the belief that when sport training focusing on competitive results begins after or during the puberty there are greater chances of success in sports compared to early sport specialization.

title: The relationship between oestrogen and muscle strength: a current perspective

description: The relationship between muscle strength and oestrogen is ambiguous and is still largely unresolved. The evidence for and against an effect of oestradiol on determinants of muscle function is equivocal and often contradictory. The bulk of the research in this area was performed during the eighties and nineties, using models of reproductive functioning such as; the menstrual cycle, the menopause and hormone replacement therapy, oral contraceptives and in vitro fertilisation treatment, to alter the female hormonal milieu. In the last decade, approximately 15 papers have demonstrated a relationship, both positive and negative, between the concentration of oestrogen and skeletal muscle strength. Conversely, around 20 articles have not shown any influence of oestrogen on a number of strength measures. The majority of these studies were performed using post-menopausal and eumenorrheic females. Most current studies use hormonal assays to confirm oestrogen status, however no recent studies have reported the bioavailable concentration of oestradiol. Similarly, no research in the last 10 years has used in vitro fertilisation treatment or pregnancy as acute and chronic models of supra-physiological changes in sex hormone concentration. Future work should focus on performing meta-analyses on each of the key components of muscle strength in an attempt to elucidate a causal relationship. In addition, models of reproductive functioning that cause the greatest magnitude of change to oestrogen concentration should be used, while controlling as many confounding factors as possible.

title: Evaluation of passive plantarflexion torque and active dorsiflexion torque in rhythmic gymnasts and nonathletes

description: The training performed by elite athletes leads to specific functional demands, producing changes on tendon and muscle properties. In the rhythmic gymnastics (RG) athletes there is a higher motor control demand in extreme plantarflexed positions. This functional demand can change the passive torque produced by the plantarflexors, as well as influence the dorsiflexion range of motion (ROM) and maximal dorsiflexion torque. We compared the dorsiflexor ROM and the influence of the passive plantarflexion torque (PPT) on the active dorsiflexion torque (ADT) between RG and nonathletes (NA) girls. The study included 10 RG and 10 NA. The dorsiflexor ROM was measured with a goniometer. The PPT and ADT were evaluated through isokinetic dynamometry at five ankle joint angles (20º, 10º, 0º, -10º, -20º). Independent T test was used to comparison between groups (α = 0.05). Pearson correlation coefficients indicated a high and moderate negative correlation between PPT and ADT for RG and NA, respectively. RG had a smaller dorsiflexion ROM than NA. The PPT was significantly higher in RG compared NA. In contrast, the ADT was higher in NA. The PPT correlation to ADT was r = -0.82; p &lt; 0.01 and r = -0.68; p &lt; 0.01, for RG and NA, respectively. Results suggest that higher mechanical loading on plantarflexors in the RG increase the PPT that influence negatively in the dorsiflexor ROM and ADT.

title: Analysis of shock absortion during gait wearing tennis shoes and military boots from Brazilian Army

description: This study aimed at comparing shock absorption during gait while walking barefoot, tennis shoes and military boots. Twenty healthy soldiers without neurologic or musculoskeletal disorders were evaluated. Subjects walked 10 meters along a straight and level walkway at a comfortable speed in barefoot condition and using tennis shoes and military boots. Two force platforms (Bertec, EUA) were placed in serial at the middle of the walkway used to measure the ground reaction forces (GRF). The kinematic system (Qualysis, Sweden) was used to measure gait speed in each test condition. The first peak of force (FPF) of the vertical component of the GRF, time to reach to FPF (T_FPF), transient impact peak force (IPF) were evaluated and the weight acceptance rate at 10% to 30%, 30% to 50%, 50% to 70%, 70% to 90% and 10% to 90% of FPF. T_FPF was 1 s shorter (p &lt; 0.0001), as well as IPF and weight acceptance rate at 10% to 30% in barefoot was higher (p &lt; 0.0001, both) than tennis shoes and military boots gait patterns. None statistical difference was found in the others analyzed variables, even as in the tennis shoes and military boots comparisons. The analyzed footwear delayed the FPF impact during gait, reduce the IPF and the weight acceptance phase during 10% to 30% of FPF, being efficient in reduce impact forces during gait.

title: Pedaling cadence effects on mechanical power and muscle contraction timing during cycling

description: The mechanical energy required to propel the crank may depend on eccentric and concentric muscle actions. However, it is uncertain whether pedaling cadence would elicit changes in concentric and eccentric contributions. Therefore, the purpose of the present study was to investigate the effects of alterations in pedaling cadence on the eccentric and concentric muscle actions. Joint power production and absorption were calculated to assess potential effects from variations in pedaling cadence on joint kinetics. Twenty-one cyclists participated in this study (VO2pico: 64.1 ± 5.0 ml/kg/min; training volume: 368.2 ± 69.5 km/week). In their first session, maximal power output (POMAX) and power output related to the second ventilation threshold (POVT2) were determined during an incremental maximal cycling test to exhaustion. In their second session, cyclists performed two 2-min trials with workload from their POVT2at two different cadences (70 and 90 rpm). Muscle activation of six muscles, pedal forces and lower limb joint kinematics were evaluated. Longer eccentric contraction at 70 rpm for vastus medialis (8%; p &lt; 0.01) and biceps femoris (20%; p = 0.04) were observed compared to 90 rpm. Longer concentric contraction for vastus medialis muscle (10%; p = 0.04) at 90 rpm was observed compared to 70 rpm. There were no differences in joint power production and absorption among pedaling cadences. No alterations in joint power could indicate maintenance of movement when pedaling cadence is changed. Eccentric contractions from knee muscles could be related to joint control, force transmission and reduced energy cost.
