abstract It is important to know about overweight and obesity situation of Brazilian children and adolescents. The present study aims to update scientific production, through a systematic review, on the prevalence and factors associated with overweight and obesity in Brazilian children and adolescents. Nine databases were verified, and 1,316 references were examined from 2018 to 2019. The electronic search was conducted by three independent researchers. All review steps followed a strategy based on PRISMA. 40 studies were included in this systematic review. Most studies use the World Health Organization classification criteria. The prevalence of overweight in Brazilian children and adolescents varies from 8.8% to 22.2% (boys: 6.2% to 21%; girls: 6.9% to 27.6%). The prevalence of obesity varied from 3.8% to 24% (boys: 2.4% to 28.9%; girls: 1.6% to 19.4%). It was observed that the socioeconomic factors (sex, skin color, economic level, region, mother's educational level, living in a rented house and without access to the internet), hereditary/genetic (family history of dyslipidemia and overweight and rs9939609 genotype) and behavioral (physical activity, screen time, eating habits, perceived body weight, health vulnerability, presence of a result close to home, alcoholic beverages, cigarette consumption) were associated with the outcome. It is concluded that the prevalence of overweight and obesity among Brazilian children and adolescents are worrisome and most of the factors associated with the outcomes are subject to change from the adoption of a healthy lifestyle.

Abstract Physical activity occurring through organized sport has been positioned as an engaging manner not only to prevent chronic-degenerative diseases but also to promote healthier societies. However, there is a lack of evidence linking competitive sport participation in the club environment in promoting youth athletes’ psychosocial development and mental health. Thus, this study aimed to analyze the effects of age, sport type, and training experience on the psychosocial development and mental health of youth Brazilian club athletes. Participants were 220 male adolescent athletes (Mean =14.09 years; SD = 2.21) from individual and team sports. Instruments included the Portuguese Youth Experience Survey for Sport (P-YES-S) and the Portuguese Mental Health Continuum – Short Form (P-MHC-SF). Correlation and multilevel linear regression analyses were performed. The results indicated a moderated correlation between both questionnaires. For the P-YES-S, model effect estimations showed variation for age in the Personal and Social Skills dimension and variations for training experience in the Cognitive Skills and Negative Experiences dimensions. For the P-MHC-SF, model effect estimations showed variation for age in the Emotional Well Being dimension and variation for sport type in Social Well Being and Psychological Well Being dimensions. More research is needed to continue examining how characteristics of sport participation are related to psychosocial development and mental health.

abstract – This study aimed to identify the prevalence of excess body weight in university students from a representative state in Brazil's southern region and establish associations with the demographic, university environment, and health behavior correlates. A random sample of 5,310 university students answered an online questionnaire with demographic, university environment, and eight health behavior data. Excess body weight was identified using the body mass index (BMI ≥ 25 kg/m2). The data were processed using bivariate analysis and hierarchical multiple regression. The overall prevalence of excess body weight exposure was equivalent to 39.1% [35.7-42.6], with significantly different rates between gender, age, and marital status. Likewise, housing type and study year showed significant associations with excess body weight. Among health behavior indicators, with control of all other variables involved in the model, depressive symptoms (p = 0.031), high stress (p = 0.045), sleep duration < 6 hours/night (p < 0.001), moderate-vigorous physical activity < 150 min/week (p = 0.022) and fruit/vegetable consumption < 5 servings per day (p < 0.001) were independently associated with the outcome. However, tobacco use, binge drinking, and prescription drug misuse did not remain in the adjusted multivariate model. In conclusion, the findings emphasize the importance of proposing and implementing multifaceted preventive intervention actions to prevent health outcomes related to excess body weight, once since significant associations with modifiable factors have been identified.

The aging process leads to deterioration in physiological functions, decreasing functional capacity. Since physical exercise reduces deleterious effects, measuring physical condition is necessary in older adults. The aim of this study was to verify the evolution of the range of motion in institutionalized sedentary older adults. The sample consisted of 19 volunteers aged 65-95 years who completed the Chair Sit-and-Reach test (CSR) and the Back-Scratch test (BS) to measure flexibility of the lower and upper limbs, respectively, before and after a period of 12 weeks without intervention. The results showed significant decrease during the control period (BS, p=0.004; CSR, p=0.001). These findings confirm that physical inactivity could lead to important loss of flexibility of institutionalized individuals, indicating decline of the elastic properties of musculoskeletal tissues and of connective tissues of joints. Therefore, the participation of institutionalized older adults in properly prescribed and guided physical exercises should be continuous and regular.

Abstract Obesity represents one of the main cardiovascular risk factors with high prevalence among the Brazilian population. The aim of this study was to assess body adiposity index (BAI) and associated factors in workers of the furniture sector. A descriptive study was conducted with 204 workers of the furniture sector in the city of Ubá-MG of both sexes aged 20-70 years. Working sector, economic class, level of physical activity, body mass index, waist circumference, abdominal circumference, waist-to-hip ratio, systolic and diastolic blood pressure, fasting glycemia, total cholesterol, high density lipoprotein, low density lipoprotein and triglycerides were assessed. Odds ratio (RC) was used to determine the strength of association among variables. Of the total number of individuals assessed, 50% had high BAI, presenting higher anthropometric, blood pressure, glucose and triglyceride values (p <0.05). It was observed that advanced age (RC: 2.76; p = 0.002) and production sector (RC: 2.52; p = 0.045) were significantly associated with BAI. According to economic class and level of physical activity, increase in BAI was observed with reduction of economic class. It could be concluded that high percentage of increased BAI was found among workers, with association with age, working sector and economic class.

Abstract To investigate the cross-validity of two equations widely used in national research to predict body mass and height in older Brazilians. Additionally, the importance of possible differences between observed and predicted BMI will be investigated with the help of equations. BM and HEI were measured using mechanical scales and portable stadiometers in a sample of 200 older women (66.6 ± 5.43 years) living in Maceió / AL - Brazil. To verify the validity of equations, the following variables were used: Student's t-test, constant error (CE), total error (TE) and standard error of estimation (SEE). To verify agreement between actual and predicted values, the Bland-Altman test was used. The comparison between BM and HEI values obtained through equations and those verified in measurements showed statistically significant differences (p <0.05). CE between predicted and measured values, TE of tested equations, as well as SEE for the prediction of variables: BM (1.66; 0.11 and 6.33), HEI (-0.02; 0.02 and 0.10) and BMI (1.47; 0.10 and 3.24) allowed determining relative values very close to actual ones (2.6%, 1.31% and 5.3% for BM, HEI and BMI respectively); however, values were not statistically significant. The equations analyzed should not be used in a general way for the population of older Brazilian women with characteristics similar to those analyzed in this study. Therefore, further studies should be carried out with the objective of constructing specific equations for the population of older women and hospitalized patients, especially the most fragile ones.
摘要:探讨在巴西国家研究中广泛使用的预测老年人体重和身高的两个方程的交叉效度。此外，观察到的BMI和预测的BMI之间可能存在的差异的重要性将在方程的帮助下进行研究。采用机械秤和便携式体重计对居住在Maceió / AL -巴西的200名老年妇女(66.6±5.43岁)的BM和HEI进行测量。为了验证方程的有效性，使用了以下变量:学生t检验、常数误差(CE)、总误差(TE)和估计的标准误差(SEE)。为了验证实际值和预测值之间的一致性，使用了Bland-Altman检验。公式计算的BM和HEI值与实测验证值比较，差异有统计学意义(p <0.05)。预测值与实测值之间的CE，检验方程的TE，以及变量预测的SEE: BM (1.66;0.11和6.33)，HEI (-0.02;0.02和0.10)和BMI (1.47;0.10和3.24)允许确定非常接近实际值的相对值(BMI、HEI和BMI分别为2.6%、1.31%和5.3%);然而，数值没有统计学意义。所分析的方程不应以一般方式用于具有与本研究中分析的特征相似的巴西老年妇女人群。因此，应开展进一步的研究，目的是为老年妇女和住院病人，特别是最脆弱的病人建立具体的方程。

Abstract The aim of the current study was to analyze players’ interactions in serve and serve return situations and examine the way points were decided due to players’ positions and surfaces. Fourteen ATP 1000 tournament matches were analyzed (7 on hard surface; 7 on clay surface). The type of surface did not affect the way points ended (χ²=9.26; p > 0.05) but did influence serve return vertical positioning (χ²=270.86; p < 0.001). The return positioning, both lateral (χ²=92.68; p < 0.001 on deuce side - χ² = 78.98; p < 0.001 on advantage side) and vertical (χ²=33.59; p < 0.001), and the type of serve (χ²=45.13; p < 0.001) affected the way points were decided. The results from the present study suggest that tennis players should use, or at least seek, strategies based on aggressiveness and consistency of the 1st serve and also indicate that in the 2nd serve return, players are more offensive, and that on hard surfaces, players stand a few steps inside the court to return the serve, differently from clay surfaces. It recommended that serve returns should combine aggression, by inside the court positioning, and accuracy.

Abstract This study compared the effects of using continuous and interval aerobic exercise during concurrent training on cardiorespiratory adaptations in women. Thirty-two participants were randomly assigned into one of the following groups: continuous running and resistance training (C-RUN, n = 10), interval running and resistance training (I-RUN, n = 11), or control group that performed resistance training only (RT, n = 11). Each group trained twice a week during 11 weeks. Oxygen uptake corresponding to the first ventilatory threshold (VO2VT1), second ventilatory threshold (VO2VT2) and maximal effort (VO2max) was measured in a maximal incremental test performed before and after training. Significant increases in VO2VT1, VO2VT2 and VO2max were observed in all training groups. VO2VT2 and VO2max presented time-group interactions, indicating that the magnitude of the increase in these variables was dependent on the training group (VO2VT2: C-Run = 6.6%, I-Run = 15.7%, RT = 1.7%; VO2max: C-Run = 7.2%, I-Run = 14.3%, RT = 2.7%). The effect size observed for post-training values comparing C-RUN and RT groups was d = 0.566 for VO2VT2 and d = 0.442 for VO2max. On the other hand, values of d = 0.949 for VO2VT2 and d = 1.189 for VO2max were verified between I-RUN and RT groups. In conclusion, the use of continuous and interval aerobic exercise during concurrent training improved different cardiorespiratory parameters in women, but in a greater magnitude when interval aerobic exercise was performed simultaneously to resistance training.

Thirty-two participants were randomly assigned into one of the following groups: continuous running and resistance training (C-RUN, n = 10), interval running and resistance training (I-RUN, n = 11), or control group that performed resistance training only (RT, n = 11). Each group trained twice a week during 11 weeks. Oxygen uptake corresponding to the first ventilatory threshold (VO2VT1), second ventilatory threshold (VO2VT2) and maximal effort (VO2max) was measured in a maximal incremental test performed before and after training. Significant increases in VO2VT1, VO2VT2 and VO2max were observed in all training groups. VO2VT2 and VO2max presented time-group interactions, indicating that the magnitude of the increase in these variables was dependent on the training group (VO2VT2: C-Run = 6.6%, I-Run = 15.7%, RT = 1.7%; VO2max: C-Run = 7.2%, I-Run = 14.3%, RT = 2.7%). The effect size observed for post-training values comparing C-RUN and RT groups was d = 0.566 for VO2VT2 and d = 0.442 for VO2max. On the other hand, values of d = 0.949 for VO2VT2 and d = 1.189 for VO2max were verified between I-RUN and RT groups. In conclusion, the use of continuous and interval aerobic exercise during concurrent training improved different cardiorespiratory parameters in women, but in a greater magnitude when interval aerobic exercise was performed simultaneously to resistance training.","PeriodicalId":38989,"journal":{"name":"Revista Brasileira de Cineantropometria e Desempenho Humano","volume":"148 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77914486","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}

Abstract The aging process causes changes in the physical and functional conditions, as well as in the foot structure and function. This study aimed to analyze the plantar pressure variation with respect to visual information and physical activity in adult and older women. This was a cross-sectional study that included 142 women (mean age of 67.8 years). Participants responded the anamnesis questionnaire, Mini Mental State Examination, and International Physical Activity Questionnaire. Plantar pressure was assessed using computerized baropodometry. Weight distribution was observed in semitandem positions for the right foot forward and then the left foot forward . Data analysis showed that foot type had no correlation with age (p = 0.37 right foot; p = 0.93 left foot) or level of physical activity (p = 0.28 right foot; p = 0.96 left foot). Moreover, plantar pressure variation showed no significant relationship with age (R2 = 0.2; p = 0.6). In conclusion, plantar pressure variation is not associated with the morphological foot type in women analyzed, as the visual condition did not generate plantar pressure variations when compared to its effect on the classification of plantar arches. Furthermore, level of physical activity was not associated with plantar pressure variation .

Abstract Extended-field-of-view ultrasonography is a valid alternative to determine the dimensions of the skeletal striated muscle; however, some factors may influence the final measurement. The aim of this study was to determine the test-retest reliability and measurement error of vastus lateralis muscle architecture variables through internal anatomical landmarks and to compare three fixed determined points using extended-field-of-view ultrasonography. Twelve young (24 ± 6 years) adult university male students participated in the study. Images were obtained through extended-field-of-view ultrasonography of the vastus lateralis muscle. Measurements were made for muscle thickness (MT), fascicle length (FL), and fascicle pennation angle (FA) using a method that identifies internal anatomical landmarks. MT was also measured at predetermined distances of 2 cm proximal, 6 cm proximal, and 2 cm distal. One-way ANOVA with repeated measures did not identify any test-retest significant differences for all variables measured. Typical measurement error in centimeters (cm) or degrees (º), coefficient of variation in percentage (%) and intraclass correlation coefficient were MT = 0.07 cm, 2.93%, 0.964; FL = 0.31 cm, 2.89%, 0.947; FA = 0.92°, 4.08%, 0.942; MT 2 cm proximal = 0.10 cm, 3.77%, 0.910; MT 6 cm proximal = 0.27 cm, 9.66%, 0.576; MT 2 cm distal = 0.35 cm, 19.76%, 0.564. MT, FL and FA showed high reliability and low measurement error. Internal anatomical landmarks proved to be more reliable and presented smaller measurement errors when compared to the predetermined distances method.
扩展视场超声检查是确定骨骼肌尺寸的有效替代方法;然而，一些因素可能会影响最终的测量结果。本研究的目的是通过内部解剖标志确定股外侧肌结构变量的重测信度和测量误差，并利用扩展视场超声比较三个固定测点。研究对象为12名年轻(24±6岁)成年大学生。通过股外侧肌的大视场超声检查获得图像。测量肌肉厚度(MT)，肌束长度(FL)和肌束夹角(FA)使用识别内部解剖标志的方法。MT也在近端2厘米、近端6厘米和远端2厘米的预定距离测量。重复测量的单因素方差分析没有发现所有测量变量的任何重测显著差异。典型测量误差以厘米(cm)或度(º)为单位，变异系数以百分比(%)为单位，类内相关系数分别为MT = 0.07 cm、2.93%、0.964;FL = 0.31 cm, 2.89%， 0.947;Fa = 0.92°，4.08%，0.942;MT 2 cm近端= 0.10 cm, 3.77%， 0.910;MT近端6cm = 0.27 cm, 9.66%， 0.576;MT 2 cm远端= 0.35 cm, 19.76%， 0.564。MT、FL和FA具有较高的信度和较低的测量误差。与预定距离方法相比，内部解剖标志被证明更可靠，测量误差更小。
