title: Body fat, but not muscle quality, is related to perceived fatigue in young-adult active and inactive women

description: Abstract The purpose of this study was to investigate the association of perceived fatigue with body composition and muscle quality (strength, thickness and specific torque) in young adult women. Fifty-one healthy women (31.98 ± 6.88 years) were assessed regarding perceived fatigue, body composition, knee extensors muscle strength, muscle thickness, and muscle quality. The short version of International Physical Activity Questionnaire was applied to classify subjects as active or inactive. To examine the relationship between perceived fatigue and dependent variables, the Pearson’s correlation was performed. Perceived fatigue was significantly correlated (p &lt; 0.05) with body weight (r = 0.469), body mass index (r = 0.369), fat mass (r = 0.469), percent body fat (r = 0.396), and relative peak torque (r = -0.378). Additionally, inactive women had significantly greater (p &lt; 0.05) body weight, body mass index, fat mass, percent body fat, and perceived fatigue than active women. Perceived fatigue is related to body weight and fat mass, but not to muscle strength or muscle quality. Moreover, physically active women showed lower perceived fatigue, body weight, and body fat compared to physically inactive women. These results suggest that body fat may play a role in perceived fatigue and physical activity could attenuate such symptom.

title: Assessment of bone mineral density in young female handball players

description: Abstract Optimizing bone mass gain during childhood and adolescence may help prevent bone diseases in advanced ages. The aim of this study was to verify the bone mineral density (BMD) and bone mineral content (BMC) in female adolescent’s handball players. This is a cross-sectional study where 68 female adolescents (12–17 years) were allocated into two groups: handball players (n = 29) (HG) and control group (n = 39) (CG). BMC and BMD from total body (TB), total body less head (TBLH), lumbar spine (L1–L4), femoral neck (FN), Ward’s triangle (WT) and respectively Z-scores were measured using dual-energy X-ray absorptiometry (DXA). Sexual maturity, menarche, PHV, time of sun exposure, physical activity level and Calcium and vitamin D intake were assessed. The HG showed significantly higher BMC, BMD as well Z-scores values (p≤0.05) of total body, TBLH, femoral neck, hip and lumbar spine than the CG. When the values were adjusted for lean soft tissue (LST) the HG showed significantly higher BMC of femoral neck (p≤0.05), as well as BMD of TBLH and femoral neck (p≤0.05) and Z-score values all bone sites except hip, than the CG. We conclude that handball players have significantly higher bone mass values compared to group of girls of the same age.

title: Community and environment for physical activity among young people: a systematic review of the Report Card Brazil 2018

description: Abstract The aim of this study was to identify evidence about the prevalence of the community and environment indicators related to physical activity (PA) among young Brazilian people. A systematic review was carried out using eight databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar) with descriptors in Portuguese and English. Community and environment Indicators included access, presence, proximity, quality, safety and pollution of/in spaces, facilities, programs available for PA among young people (up to 18 years-old), which may be measured subjectively and/or objectively. A total of 23 documents were included, representing 15 different studies. There were more studies in the South region (n=8), followed by the Northeast (n=3) and Southeast (n=3). Self-reported instruments were more frequently used (n=15). The studies reported prevalence of perception (positive and/or barrier) for access to facilities, programs and/or parks (n=13); presence of sidewalks and bicycle lanes (n=4); proximity to residence (n=5); quality (n=5); safety from crime and traffic (n=14) and pollution (n=6); number of spaces and/or facilities around the residence (n=1); and observation of adolescents using public spaces for PA (n=3). The prevalence rates showed high variability according to environmental indicator. No studies are available for the North and Midwest of the country. Distinct environmental measures were used in self-reported studies, impairing data comparability. To date, no studies have been identified that provide information about the prevalence of combined environmental measures (perceived and objective).

title: Prevalence of weight excess in Brazilian children and adolescents: a systematic review

description: Abstract The prevalence of obesity is rapidly increasing worldwide, no mattering age groups and socioeconomic status. In Brazil, it is still unclear the prevalence of obesity in children and adolescents, since most Brazilian studies have only verified regional prevalence of obesity. Therefore, the aim of the present study was to analyze the scientific production regarding the prevalence of weight excess in Brazilian children and adolescents. A search in the relevant electronic databases Medline/Pubmed, Web of Science, Lilacs, Scielo and BVS was performed. After analyzing 61 studies, the overall prevalence was 25.5%. When sample was stratified weight excess degree, a prevalence of 17% and 11.6% for overweight and obesity were observed, respectively. Analyzing differences by sex, boys presented higher prevalence of overall weight excess (e.g., 26.4% vs 23.5%), overweight (17% vs 16%) and obesity (11.9% vs 9.1%) than girls. With respect to Brazilian regions and its differences, individuals from southern presented the highest prevalence of overall weight excess (33.2%) and overweight (20.1%). The southeastern region showed the highest prevalence of obesity (18.2%). The results obtained in the current study indicate that Brazil presents a scenario of crescent increasing on the prevalence of weight excess. These results are in accordance with studies from other countries, and reinforce the increase of the overall weight excess prevalence in Brazilian children and adolescents, highlighting the increasing of obesity rates, since it is a more concerning condition than overweight. Therefore, preventive measures to reduce weight excess increase, as well as treatment programs aiming to tackle obesity in childhood should be public health system top priority.

title: Predictive factors of the attack efficacy: the case of the Brazilian women’s Volleyball League champion team

description: Abstract The aim was to identify the predictive factors of the attack efficacy of the Brazilian women’s League Champion team according to the level of performance of the opposing team.The sample was composed of the observation of 1137 attacks in 21 games of the 2015-2016 Brazilian women’s Volleyball League champion team. The results were significant to identify the predictive factors of the attack efficacy against high (.2=110.562; .&lt;0.00001), intermediate (.2=64.134; .&lt;0.00001) and low (.2=62.137; .&lt;0.00001) performance opponents. Thus, it is concluded that when playing against high- performance teams, powerful attack for position 6 and second attack tempo increase the chances of attack point; powerful attacks for position 1 and 5 reduce the chances of game continuation; and powerful attack for position 6 increases the chances of blocking. In addition, in games against intermediate-performance teams, reception that allows organized attack without all attack options reduces the chances of attack point and game continuation, while the reception effect did not seem to be a predictive factor of the attack efficacy in games against high- and low-performance opponents and, finally, in games against low-performance teams, powerful attack for position 1 reduces the chances of game continuation and attack blocking.

title: Assessment of critical velocity in track and treadmill: physiological profiles and relationship with 3000-meter performance

description: Abstract The present study aiming to verify the interference of different conditions (treadmill vs. track) on critical velocity (CV) values, as well as on the correlation to the 3000-meter performance (v3000m), and thus infer about the specificity of each values as training parameter for this distance. Seven runners (15.3±1.4 years) were submitted to a maximal progressive test (1.0 km×h-1 increments per minute until exhaustion) to assess V̇O2max and maximal aerobic velocity (vV̇O2max). Subsequently, CV was estimated from three running performances at each test condition, with exercise intensities adjusted for different time limits (tLim) at 900, 2100 and 3300 meters in track or at 90, 95 and 115% of vV̇O2max in treadmill. From linear adjustments, using stepwise method, CV was assessed on treadmill (CVTREADMILL) and track (CVTRACK), and both compared by the Mann-Whitney test. The sample-adjusted dispersion coefficient (R2adj) analyzed the variance of v3000m with CVTRACK, CVTREADMILL and vV̇O2max. In all analyses, significance was set at P≤0.05. In progressive test, V̇O2max reached 54.2±5.2 mLO2×kg-1×min-1 and vV̇O2max reached 16.8±1.9 km×h-1. No differences were observed between CVTREADMILL and CVTRACK (14.0±1.8 vs. 12.3±3.2 km×h-1, P=0.46). Correlations were observed for v3000m with CVTREADMILL (R2adj ~0.94), CVTRACK (R2adj ~0.99) and vV̇O2max (R2adj ~0.90), all showing P=0.001. It could be concluded that no influence was observe on the ability to achieve identical CV values from different assessment conditions. The correlation to the v3000 meters suggested better specificity of CVTRACK than CVTREADMILL for training prescription and performance control.

title: Longitudinal follow-up of physical activity from preschool to school age: the ELOS-Pré study

description: Abstract The aim of this study was to verify if the practice of physical activity in the preschool age (3-5 years) is predictive of this behavior after entering the school age (5-7 years).A longitudinal, school-based study with 700 children enrolled in public and private schools of the city of Recife, Pernambuco, who were evaluated in 2010 and followed in 2012. The study variables were the time spent in outdoor games and plays (a measure referred to by the parents / guardians of children through questionnaire applied as an interview) and the level of physical activity (objective measure obtained by the Actigraph accelerometer). The latter measure was extracted from a subsample (n = 98) of children. To analyze data, binary logistic regression was used. Children who spent 60+ minutes per day in this type of activity were 45% more likely of maintaining this behavior after entering the school age (OR = 1.45, 95% CI 1.02-2.07, p = 0.04). In addition, children who presented global NAF measure of 300+ counts / minute in 2010 were 173% more likely of maintaining this level of physical activity after entering the school age (OR = 2.73, 95% CI, 98-7.59, p = 0.06). It was verified that the practice of physical activity in the preschool age is a predictor of this behavior after entering the school age. It is suggested the development of campaigns to inform parents and teachers about the importance of early adherence to physical activity recommendations.

title: The prevalence of global physical activity among young people: a systematic review for the Report Card Brazil 2018

description: Abstract The aim of this study was to summarize data on the prevalence of global physical activity (PA) among children and adolescents in Brazil. This systematic review included an electronic search in 8 databases (PubMed, Scopus,Web of Science, LILACS, SPORTDiscus,BIREME,Scielo, and Google Scholar) and a manual search in the references of retrieved studies.Observational studies that assessed global PA among Brazilian children and adolescents were included. A narrative approach toward results was adopted. An initial database search reached 3276 potentially relevant titles (2534 titles after duplicate analysis); 92 (62 different studies) met all inclusion criteria. Studies were carried out between 2001 and 2015; most studies were conducted in Southern and Northeastern Brazil.Three were nationwide surveys (4.8%), but no studies included children aged 0-5 years. Eighteen different instruments for PA measurement were used; only two studies used objectively-measured PA. The most used definition was ≥ 300 minutes/week of moderate-to-vigorous PA. The overall proportion of young people who were physically active ranged from 6.5% to 92.3%.Fourteen studies (22.6%) found a prevalence of ≥ 50%. Three nationwide surveys reported the prevalence of physically active students ranging from 29.0% to 66.0%. A wide variability of PA estimates were found. Important research gaps (e.g., studies with objectively-measured PA, children aged up to 6 years-old and in Northern Brazil) should be considered to develop new research studies in Brazil.

title: Prevalence of Brazilian children and youth who meet health criteria for cardiorespiratory fitness: systematic review

description: Abstract The study aimed to systematically review the literature to identify the prevalence of Brazilian children and adolescents that meet health criteria for cardiorespiratory fitness (CRF). The search was performed in the electronic databases (PubMED, SciELO, LILACS, Scopus, SPORTDiscus and Web of Science) and list of references of identified articles. Inclusion criteria were: population composed of children and/or adolescents (0-19 years or average age up to 19 years); studies with Brazilian children and/or adolescents and observational studies with cross-sectional or longitudinal design. The process of analysis of studies involved reading titles, abstracts and full texts. After these phases, 60 articles were eligible. Regarding the design, two studies were longitudinal. Of the total studies included, 49 presented moderate methodological quality values and 11 presented low methodological quality values, according to National Heart, Lung, and Blood Institute instrument. The prevalence of children and adolescents who met CRF health criteria varied among studies (7.5% to 70.4%), and this variation was higher in girls than in boys. Total of 49.093 individuals aged 6-19 years were surveyed to compute all of these studies, resulting in 32.2% of subjects (27.7% of boys and 28.4% of girls) with CRF levels adequate for health around Brazil. These results may help to screen the pediatric population at risk if CRF is considered as a health measure.
