Meta-analytical studies have indicated that isometric handgrip training promotes significant reduction in blood pressure in hypertensive patients with similar or greater decreases in blood pressure than observed after aerobic and dynamic resistance training. However, several gaps in the literature still need to be addressed. Thus, we designed the ISOPRESS network group, which consists of a task force of different research groups aimed at analyzing the effects of isometric handgrip training on different contexts, parameters, and populations. Thus, the aim of this study was to describe the rationale and design behind the ISOPRESS, presenting the methods employed. The ISOPRESS questions involve whether isometric handgrip training is effective in hypertensives in different settings (ISOPRESS 1 – unsupervised training and ISOPRESS 2 – public health system), whether it works in patients with other cardiovascular diseases (ISOPRESS 3 – obstructive sleep apnea and ISOPRESS 4 – peripheral artery disease) and what are the mechanisms underlying the effects of isometric handgrip training in hypertensives (ISOPRESS 5 – neural mechanism). The study will yield information on the effectiveness of isometric handgrip training in different settings and patients with other cardiovascular diseases. Finally, it will help to understand the mechanisms involved in reducing blood pressure in hypertensives.

Aims: The relative age effect (RAE) has been a research subject in several fields of society. RAE is present in different sports, influencing the young athlete’s opportunities of participation. The aim of this study was to analyze the occurrence of RAE in Brazilian elite men and women futsal. Methods: Birthdate of 376 athletes from Brazilian Men National Futsal League (LNF)/2013 and 227 from Brazilian Women National Futsal League/2014 were collected on leagues’ homepages and divided into four quarters (Q1:January-March, Q2:April-June, Q3:July-September and Q4:October-December) and two semesters (S1:January-June, S2:July-December). In men case, results were compared with Penna and Moraes (2010) data on LNF/2009. Chi-square test was used to analyze differences between distributions of birthdates by quarters and semesters. The significance level was set at α<0.05, with Bonferroni correction when necessary. Results: there is RAE in men futsal, predominantly on athletes born in first semester. In women futsal, there is no evidence of RAE. Conclusions: On men futsal, there is a need for offering similar opportunities to young players, while on women, the small amount of athletes in Brazil must be regarded as an alert to the culture of futsal as a men social space, which deters the entry of new practitioners.

Aims: To advance knowledge of long-term development of basketball players, this study investigated age and sex differences in game-related statistics which discriminate winners from losers in World Basketball Championships held after the 2010 rule change. Methods: A total of 935 games from six categories (under-17, under-19 and open age for both men and women) were analyzed. All games were classified into three types (balanced, unbalanced and very unbalanced) according to point differential by a k-means cluster analysis. A discriminant analysis was performed to identify game-related statistics which discriminate winners from losers in each game type. An absolute value of a structural coefficient (SC) equal to or above 0.30 was considered relevant for the discrimination. Results: In balanced games, assists discriminated winners from losers in open games (men, |SC| = 0.32; women, |SC| = 0.34), whereas successful free throws did so in under-17 games (men, |SC| = 0.30; women, |SC| = 0.31). Successful 2-point field goals discriminated winners from losers only in women’s games (under-19, |SC| = 0.38; open, |SC| = 0.36). Conclusion: There were three novel findings in balanced games: 1) successful free throws but not assists discriminated winners from losers in under-17 games; 2) successful 2-point field goals discriminated winners from losers in women’s games but not in men’s games; and 3) discriminating power of successful 3-point field goals was extremely small in women’s games. These results may be related to the new rules for the shot clock and the 3-point distance.

Aim: to analyze the pattern and trends of use of screen-based devices and associated factors from two surveys conducted on public high school students in Caruaru-PE. Methods: two representative school-based crosssectional surveys conducted in 2007 (n=600) and 2012 (n=715) on high school students (15-20 years old). The time of exposure to television (TV) and computer/videogames PC/VG was obtained through a validated questionnaire, and ≥3 hours/day was considered as being excessive exposure. The independent variables were socioeconomic status, school related, and physical activity. Crude and adjusted binary logistic regression were employed to examine the factors associated with screen time. The statistical significance was set at p<0.05. Results: There was a significant reduction in TV time on weekdays and total weekly, but no change in the prevalence of excessive exposure. The proportion of exposure to PC/VG of ≥3 hours/day increased 182.5% on weekdays and 69.5% on weekends (p <0.05). In 2007, being physically active was the only protection factor for excessive exposure to total screen time. In 2012, girls presented less chance of excessive exposure to all screen-based devices and total screen time. Other protective factors were studying at night and being physically active (PC/VG time), while residing in an urban area [OR 5.03(2.77-7.41)] and having higher family income [OR 1.55(1.04-2.30)] were risk factors. Conclusion: Significant and important changes in the time trends and pattern of use PC/VG were observed during the interval of 5 years. This rapid increase could be associated with increased family income and improved access to these devices, driven by technological developments.

Aim: To compare the anthropometric, metabolic, and inflammatory parameters of overweight adolescents after 12-weeks of resistance and aerobic training (CT), taking into account the Gln27Glu polymorphism of the β2 adrenergic receptor (ADRB2) gene. Methods: Forty-seven adolescents (15.05±1.07y) were assigned to one of four groups, according to the presence or absence of the Glu27 allele: CT (CarrierT n=11; NoncarrierT n=11) or control (CarrierC n=13; NoncarrierC n=12). Body composition, abdominal fat, maturation, fitness, metabolic and lipid profile, inflammatory markers were assessed. The CT consisted of six resistance exercises, followed by 30 min of walking/ running at 50-80% VO2max, totaling 60 min/session, three times a week. A mixed-model factorial ANOVA was used to compare variables at baseline and after 12-weeks. Results: TC was effective in reducing total fat mass (NoncarrierT ES=.45, CarrierT ES=.27) and subcutaneous abdominal fat (NoncarrierT ES=.48, CarrierT ES=.46) and increasing lean mass (NoncarrierT ES=.58, CarrierT ES=.60) and fitness. CarrierT group showed a reduction in leptin (ES=.49). Conclusion: The responses of body composition and physical fitness to TC were not influenced by the presence of the Gln27Glu polymorphism. However, only the Glu27 allele carriers showed reductions in leptin after 12-weeks. Besides, a lack of intervention caused obesogenic effects, especially in Glu27carriers.

Aims: to design reference percentile curves of waist circumference (WC) in children aged 6–10 from municipalities of developed (Portugal) and developing (Brazil) countries and to compare these results with other international references. Methods: this cross-sectional study enrolled a 6–10-year-old probability sampling. Univariate analysis of covariance adjusted by height was carried out to test the main effects of age, sex, countries, and interactions. WC percentile curves were performed with the LMS Chart Maker. Results: The sample comprised 6,475 children. Portuguese children presented a curvilinear increase in WC curves and Brazilian WC curves have shown a linear increase with age both for boys and girls. Overweight and obesity prevalence was 15.9 % and 4.7 % for Portuguese children and 12.9 % 4.5% for Brazilian children, respectively. There was a main effect (p<0.0001) for age and countries, and an interaction effect for sex*age (p=0.001) and countries*age (p<0.0001). Portuguese boys and girls have shown higher values for the 50th, 75th, and 95th percentiles than Brazilian boys and girls. Conclusions: WC reference percentile curves were drawn for 6–10-year-old Portuguese and Brazilian children. Portuguese children have higher WC values than Brazilian children and other children from developed countries.

Portuguese boys and girls have shown higher values for the 50th, 75th, and 95th percentiles than Brazilian boys and girls. Conclusions: WC reference percentile curves were drawn for 6–10-year-old Portuguese and Brazilian children. Portuguese children have higher WC values than Brazilian children and other children from developed countries.","PeriodicalId":267352,"journal":{"name":"Motriz-revista De Educacao Fisica","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116628205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
