RESUMO. Objetivo: Analisar a associação entre insatisfação com a imagem corporal e autoestima de adolescentes matriculados na rede pública estadual de ensino fundamental em Salvador-Bahia. Método: Participaram deste estudo de corte transversal 860 adolescentes de 10 a 19 anos de idade, de ambos os sexos, matriculados do 7º sétimo ao 9º nono ano em 12 escolas de médio porte da rede pública estadual do ensino fundamental em turno integral, do município de Salvador, Bahia. A autoestima foi avaliada por meio da Escala de Autoestima de Rosenberg e a insatisfação com a imagem corporal pelo Body Shape Questionnaire. Dados demográficos e socioeconômicos, maturação sexual, estado antropométrico, nível de atividade física e sedentarismo foram também avaliados. A associação entre insatisfação com a imagem corporal e autoestima foi analisada pela regressão multinominal para variáveis politômicas utilizando o programa estatístico SPSS, versão 23.0. Resultados: Entre os adolescentes, 24,8% tinham moderada autoestima e 27,3% apresentaram os menores escores desse constructo. A insatisfação com a imagem corporal foi identificada em 25,2% dos adolescentes. A análise de associação revelou que adolescentes com insatisfação com a imagem corporal possuem 5,61 (IC 95% 3,08-10,24) vezes maior chance em manifestar baixa autoestima para o sexo feminino e 3,83 (IC 95% 2,03-7,25) vezes para o sexo masculino. Ainda entre as meninas, a insatisfação com a imagem corporal permaneceu associada positivamente à moderada autoestima após ajuste do modelo (OR: 2,31; IC 95% 1,21-4,41). Conclusão: Foi observada alta prevalência de níveis baixos e moderados de autoestima e que a insatisfação com a imagem corporal influenciou a baixa autoestima em ambos os sexos e a moderada entre as meninas.

ABSTRACT. Objective: To analyze an association between dissatisfaction with body image and self - esteem of adolescents enrolled in the public elementary school system in Salvador - Bahia. Methods: Participated in this cross-sectional study 860 adolescents aged 10 to 19, of both sexes from the 7th to the 9th year, enrolled in twelve medium-sized schools of the public elementary school system in full shift, in the city of Salvador, Bahia. Self-esteem was assessed through the Rosenberg Self-esteem Scale and body image dissatisfaction by the Body Shape Questionnaire. Demographic and socioeconomic data, sexual maturation, anthropometric status, physical activity level and sedentary lifestyle were evaluated. The association between dissatisfaction with body image and self-esteem was analyzed by multinominal regression for polytomic variables using the statistical program SPSS Version 23.0. Results: Among the adolescents, 24.8% had moderate self-esteem and 27.3% had the lowest scores of this construct. Body image dissatisfaction was identified in 25.2% of the adolescents. The association analysis revealed that adolescents with body image dissatisfaction have 5.61 (95%ci 3.08-10.24) times greater chance of manifesting low self-esteem for females and 3.83 (95%ci 2.03-7.25) times for males. Still among girls, dissatisfaction with body image remained positively associated with moderate self-esteem after adjusting the model (OR: 2.31; 95%ci 1.21-4.41). Conclusion: It was concluded that the prevalence of low and moderate self-esteem was high, and dissatisfaction with body image influenced low self-esteem in both sexes and a moderate among girls.

Establishing Cephalometric Norms in Primary Dentition Using Comprehensive Craniofacial Growth Analysis - A Digital Cephalometric Study

ABSTRACT Objective: To establish cephalometric norms in primary dentition among males and females using novel customized Comprehensive Cephalometric Growth (CCG) Analysis. Material and Methods: The study was conducted on 67 subjects with a mean age of 5.5 yrs. Digital lateral cephalometric radiographs were obtained using Planmeca Pro One. The digital images were then transferred to Nemoceph software. Craniofacial Growth (CCG) Analysis was configured in the software with five sub-groups. This sub-grouping was done such that related components were grouped together and comprehensively; it would provide an assessment of every component of the craniofacial region that could be affected either by treatment maneuver or growth process. The same was used for the cephalometric analysis and to determine the cephalometric norms in the primary dentition. Results: Certain linear measurements were higher among males when compared to females. However, most measurements remained similar among males and females during this age group. The CCG analysis provided a comprehensive knowledge of the craniofacial parameters during the growth process. Conclusion: The cephalometric norms during primary dentition thus established using Comprehensive Craniofacial Growth analysis would provide the data for early diagnosis and treatment planning in interceptive orthodontic treatment procedures.

Fatores associados à satisfação e distorção da imagem corporal em crianças de 7 a 10 anos de idade / Factors associated with satisfaction and distortion of body image among children from 7 to 10 years of age

RESUMO O objetivo deste estudo é analisar a satisfação e distorção da imagem corporal em crianças de 7 a 10 anos de idade e verificar quais fatores antropométricos e socioeconômicos estão associados a elas. Trata-se de um estudo transversal, realizado com 307 crianças de escolas públicas de Goiânia. A saúde da criança e os aspectos socioeconômicos da família foram avaliados por meio de um questionário semiestruturado; a imagem corporal foi avaliada por meio da Escala de Silhuetas Brasileiras Para Crianças; e também foram coletados dados antropométricos de peso, estatura, dobras cutâneas e circunferência da cintura. Observou-se homogeneidade do gênero neste estudo, predomínio de meninos (52%) eutróficos (73%). Apesar de se tratar de uma amostra com peso saudável, a insatisfação e a distorção da imagem corporal prevaleceram sobre a maior parte da amostra: a insatisfação esteve presente em 92% das crianças, prevalecendo o desejo por uma menor silhueta, enquanto a distorção esteve presente em 75% da amostra, com predomínio da subestimação da silhueta. No entanto, este estudo encontrou associação da insatisfação com a imagem corporal apenas com IMC (aferido, atual e desejado) e circunferência da cintura; e associação da distorção da imagem corporal apenas com os IMC (aferido e atual).

ABSTRACT The aim of this study is to analyze the satisfaction and distortion of body image in children from 7 to 10 years old and to verify which anthropometric and socioeconomic factors are associated with them. This is a cross-sectional study, carried out with 307 children from public schools in Goiânia. The child's health and the socioeconomic aspects of the family were assessed using a semi-structured questionnaire; body image was assessed using the Brazilian Silhouettes Scale for Children; and anthropometric data on weight, height, skinfolds and waist circumference were also collected. Gender homogeneity was observed in this study, with a predominance of eutrophic(73%) boys (52%). Despite being a sample with a healthy weight, dissatisfaction and distortion of body image prevailed over most of the sample: dissatisfaction was present in 92% of children, the desire for a smaller silhouette prevailing, while distortion was present in 75% of the sample, with a predominance of underestimation of the silhouette. However, this study found dissatisfaction association with body image only with BMI (measured, current and desired) and waist circumference; and association of the distortion of the body image only with the BMI (measured and current).

Concordancia en la medición testicular de varones adolescentes con 3 métodos de orquidometría / Concordance of testicular measurement in male adolescents with three methods of orchidometry

Introducción. El orquidómetro de Prader es el método estándar para medir el volumen testicular (VT) en niños y adolescentes. Objetivo. Evaluar la concordancia en la estimación del VT y del inicio puberal con las técnicas de orquidometría de Prader, Chipkevitch y Sotos. Métodos. Diseño descriptivo transversal realizado en varones de entre 9 y 20 años. Se midió el VT (ml) en cada adolescente con las técnicas de Prader (método de referencia), Chipkevitch (modelo gráfico) y Sotos (medición de ancho testicular con regla plástica y fórmula equivalente a ecuación elipsoide). Se excluyeron varones con patología urogenital y enfermedades que afectan el crecimiento testicular. Para la concordancia entre métodos, se utilizó kappa para el inicio puberal, y coeficiente de correlación intraclase (CCI) y gráficos de Bland-Altman (GBA) para el VT. Resultados. Se incluyeron 377 varones sanos. Para la concordancia en VT (ml), la comparación Prader-Chipkevitch obtuvo CCI: 0,994 y p < 0,001; y de CCI; 0,312 y p < 0,001 para la de Prader-Sotos. En los GBA se halló una media de las diferencias cercana a 0 ml en la comparación Prader-Chipkevitch y cercana a 8 ml en la de Prader-Sotos. El acuerdo en el inicio puberal obtuvo un valor de kappa 0,93 en la comparación Prader-Chipkevitch y de 0,75 en la de Prader-Sotos. Conclusión. Los orquidómetros de Prader y Chipkevitch tienen una excelente concordancia en la estimación del VT y el inicio puberal; por lo tanto, podrían intercambiarse en la atención diaria de varones adolescentes. El método de Sotos mostró una concordancia buena en la estimación del inicio puberal, pero baja en la medición del VT

Introduction. The Prader orchidometer is the standard method used to measure testicular volume (TV) in children and adolescents. Objective. To assess the concordance in the estimation of TV and puberty onset with the Prader, Chipkevitch, and Sotos orchidometric techniques. Methods. Cross-sectional descriptive study conducted among male children and adolescents aged 9-20 years. For each adolescent, TV was measured with the methods by Prader (gold standard), Chipkevitch (graphic model), and Sotos (measurement of testicular width with a plastic ruler and use of a formula equivalent to the ellipsoid equation). Male children and adolescents with urogenital conditions and disorders affecting testicular growth were excluded. Kappa statistics was used to determine concordance among methods for puberty onset, and intraclass correlation coefficient (ICC) and Bland-Altman (B&A) plots for TV. Results. In total, 377 healthy males were included. Regarding the concordance for TV (mL), the Prader-Chipkevitch comparison obtained an ICC of 0.994 and a p < 0.001; while the Prader-Soto comparison obtained an ICC of 0.312 and a p < 0.001. With the B&A plots, mean differences were close to 0 mL in the Prader-Chipkevitch comparison and close to 8 mL in the Prader-Sotos comparison. Concordance for puberty onset obtained a kappa value of 0.93 and 0.75 in the Prader-Chipkevitch and Prader-Sotos comparisons, respectively. Conclusion. The Prader and Chipkevitch orchidometers show an excellent concordance in estimating TV and puberty onset; therefore, both methods could be used interchangeably in the daily care of male adolescents. The Sotos method showed a high concordance in estimating pubertal onset, but low in measuring TV.

Assessment of the upper limbs maximum power and the locomotion speed in amputee football players

Abstract Aim: The purpose of the study was to assess upper limbs' maximum power and locomotion speed among amputee football (amputee soccer) players. Methods: The 30-s Wingate Anaerobic test and the 20-m sprint test were performed. Anthropometric measurements and body composition (Body mass index (BMI), percentage of body fat (% BF), and lean body mass (LBM)) were examined. Results: BMI significantly differentiated forwards and defenders (p < 0.05). Peak power (PP) and mean power (MP) were related to LBM (p < 0.05), thus defenders reached higher values of PP, in comparison to forwards. % BF and BMI were related to relative mean power (rMP) (p < 0.05). Field position differentiated players in terms of upper limbs' relative peak power (rPP) in favour of forwards (p < 0.05). Age was a significant factor for speed velocity on 10 m and 20 m (p < 0.05). There was no relationship between upper limbs' power and locomotion speed. Conclusion: Body composition, especially % BF may influence on the anaerobic performance of amputee football players.

Effect of the inclusion of static stretching in general warming up on muscle strength in Brazilian army military personnel

Abstract Aim: Several health professionals prescribe static stretching exercises (SS) as essential for those that practice physical exercises, for injury prevention and performance improvement, although there is still no consensus. There are few studies on the effects of SS use on warming up. Thus study aimed to compare the effects of the inclusion of SS in general warming up procedures on muscle strength in Brazilian army personnel. Methods: Thirty-two young military men were selected. They were subjected to anthropometric evaluation and performed knee extension and flexion in an isokinetic digital dynamometer, at a speed of 60°/s. Then, they were divided into two randomized and counterbalanced groups, Traditional Group (TG) and Experimental Group (EG). The TG performed the lower limbs warm-up protocol provided for military physical training (MPT) and immediately after, performed the isokinetic muscle strength test. The EG performed the same protocol, performing the SS in the hamstrings and quadriceps, before warming up. Results: An increase was found in the peak isokinetic torque in the knee extension of the EG (Pre: 209.80 ± 21.36 vs Post: 243.98 ± 30.35; p = 0.001) and flexion (Pre: 130.86 ± 18.63 vs Post: 142.41 ± 25.92; p = 0.006). In the TG, significant differences were found in the extension of the knee, but not in flexion (Pre: 209.14 ± 34.27 vs. Post: 239.38 ± 36.17; p = 0.001 and Pre: 129.23 ± 18.43 vs Post: 133.66 ± 13.20; p = 0.297, respectively). Conclusion: The inclusion of SS in general warming up did not harm and even improved muscle strength performance in knee extension and flexion in Brazilian Army military personnel.

Waist Circumference Above 80 cm Predicts Increased Systolic Blood Pressure in Healthy Young Adult Women

Abstract Background: Among anthropometric measures for assessing adiposity-related risk, waist circumference (WC) is simple and fast to perform. Cut-off values for WC proposed by the International Diabetes Federation (IDF), and the Adult Treatment Panel III of the National Cholesterol Education Program (NCEP-ATP III) are categorized by gender and are not age-specific. Objective: To analyze the association between WC and cardiometabolic risk factors in adult women. Methods: A total of 164 healthy adult women were grouped by WC according to IDF and NCEP-ATP III cutoff values. Continuous variables were described as mean ± standard deviation or median (interquartile range). The Shapiro-Wilk test was used to assess the normality of data. Variables were analyzed by unpaired Student's t-test, Mann-Whitney U and Kruskal-Wallis tests. The correlation of WC categories with systolic (SBP) and diastolic (DBP) blood pressure, fasting blood glucose, high-density lipoprotein cholesterol (HDL-c), and triglycerides were examined by Spearman's rho correlation coefficient and linear regression analysis. A p value < 0.05 was considered statistically significant. Results: Increased WC showed a significant correlation with SBP, DBP, glucose, HDL-c, and triglycerides. In bivariate linear regression, approximately 63.0 % of the variability of SBP (≥ 130 mmHg) among the age group 20-40 years was predicted by increased WC according to both criteria. Conclusion: A WC above 80 cm in women aged 20-40 years strongly predicted variability in SBP, calling attention to the importance of measuring WC for the monitoring and prevention of cardiovascular and metabolic diseases in women in this age group.

Acute Strength Exercise Decreases Satiety by Modifying Blood Cytokines Levels in Physically Active Men

Abstract Aim: Exercise elicits adaptations in several physiological systems, such as the gastrointestinal tract. We evaluated the effects of an acute strength exercise (acute-SE) on gastric satiety and its correlation with creatinine kinase (CK), lactate, and plasma cytokine levels in humans. Methods: Anthropometric parameters, body composition, muscular strength, and satiety (drink test protocol) at rest and exercise were assessed. Results: In the squat, bench press, and T-bar row exercises, we observed a significant decrease (p<0.05) in muscular strength in the second, third, and fourth sets compared with that in the first set. Compared with rest, we observed a significant increase (p<0.05) in CK and lactate levels after acute-SE. In the drink test, acute-SE significantly increased (p <0.05) the total intake, calories ingested, and a total time of ingestion. Concerning cytokines, there was a significant increase (p<0.05) after acute-SE of IL-1β and IL-6 levels at the beginning of the test and a decrease in IL-6, -10, -13, and TNF-α levels after acute-SE at the end of the test (p<0.05). There was a correlation between CK, lactate, and total intake after acute-SE (p<0.05) as well as between IL-6, 13, TNF-α, and volume ingested in the last score of the drink test after acute-SE (p<0.05). Conclusion: Acute-SE decreases satiety associated with changes in lactate, CK, and plasma cytokine levels in healthy humans.

Intra and inter-rater agreement of the Dynamic Movement Assessment ™ Agreement of the DMA™

Abstract Aims: To investigate the inter-and intra-rater agreement of the Dynamic Movement Assessment (DMA™) risk classification. Method: In this study, after the anthropometric measurements were made, 17 female soccer athletes were filmed performing the six DMA™ tests (full squat, step-up, single-leg squat, jump test, test plank, and side plank). Both, major and secondary deviations, were observed during the tests. Two experienced health professionals performed video analysis using Kinovea 8.15.0 (inter-rater agreement). To assess the intra-rater agreement, the same video analysis was performed two months later. Participants were rated from 0 to 21 points and at low, medium, moderate, and high risk of developing musculoskeletal injuries. To assess the reliability of the assessment of movement patterns of DMA, the intraclass correlation coefficient (ICC) was performed with a 2-way random-effects model with an absolute agreement (inter-rater) and a 2-way mixed-effects model and consistency (intra-rater). Weighted Kappa Agreement Analysis (kw) was performed with linear weights to assess the level of agreement related to the risk classification of DMA (high, moderate, medium, or minimum). The Analysis was performed with StatsDirect v.3 and SPSS (23.0). Results: Comparing the number of points between the inter-and intra-rater, the ICC was 0.91 (95% CI = 0.74-0.97) and 0.84 (95% CI = 0.59-0.94), respectively, with kw = 0.46 (P = 0.02) intra -rater and kw = 0.46 (P = 0.006) inter-rater (Table 9). Conclusion: DMA has excellent inter-and intra-rater reliability to evaluate movement patterns and classify the risk of musculoskeletal injuries.

The influence of maturational and morphological status pre- and post-menarche on the 100-m freestyle swimming performance of competitive teenagers

Abstract Aim: This study investigated whether the difference anthropometric of swimmers pre- and post-menarche influence the motor performance of a 100-m freestyle swimming test. Methods: Twenty-five female swimmers participated in this study, nine swimmers have not had menarche (age 11.7 ± 0.63), and sixteen swimmers already have had it (age 15.17 ± 1.36). Body composition (skinfold thickness), anthropometrical parameters (height and weight), and biological age (Tanner self-assessment) were measured. A univariate and multivariate linear regression analysis was run to assess which personal or anthropometric variable predicts the motor performance (time trial) on a 100-m freestyle swimming test in pre- and post-menarche participants. As well, it was performed a Pearson's correlation test between the maturational status on Tanner self-assessment and the motor performance. Results: Post-menarche swimmers demonstrated better motor performance than pre-menarche swimmers. Anthropometric characteristics did not predict the motor performance of pre-menarche swimmers. Age, height, and weight predicted 47.8% of the motor performance of post-menarche swimmers. The Tanner classification demonstrated a strong negative correlation with swimming performance. Conclusion: Anthropometric characteristics only impacted the motor performance of post-menarche swimmers.

Performance comparison in the Wingate test between standing and seated positions in competitive cyclists

Abstract Aims: The current study aimed to compare the anaerobic power output through the Wingate test in different positions, i.e., standing and seated, and identify the relationship between power-output and body mass. Methods: Eleven male competitive cyclists (age: 30.3 ± 4.7 years; body mass: 73.7 ± 7.7 kg; body fat: 11.3 ± 4.2%) were submitted to two sessions of the Wingate test (WT) in different positions, on different days. Results: The peak power (W), average power (W), relative peak power (W·kg-1), relative average power (W·kg-1), average cadence (rpm), and average velocity (km·h-1) presented significant differences in the standing position compared with the seated position (p < 0.05), 1155 ± 130 vs. 1082 ± 182 (W), 875 ± 96 vs. 818 ± 116 (W), 15.9 ± 1 vs. 15.0 ± 2 (W kg-1), 12.1 ± 1 vs. 11.3 ± 1 (W kg-1), 117.5 ± 7 vs. 109.8 ± 10 (rpm), 37.0 ± 2 vs. 34.6 ± 3 (km·h-1), respectively. However, when controlled the body mass, the differences in variables power output ceased to exist (p > 0.05). The fatigue and peak heart rate (bpm) indices did not present significant differences between the tests (p > 0.05). Conclusions: Sprint performance was improved when the WT was performed in a standing position in competitive cyclists. The study also reports the important relationship between body mass and anaerobic production capacity in the WT, emphasizing that it is desirable an increase in lean body mass and a reduction in fat mass, similar in competitions. We suggest that, for anaerobic assessment in cyclists, the standing position should be used during the WT, to determine the maximum power-output capacity.

Subacute effects of the number of Pilates exercise series on cardiovascular responses in hypertensive women

Abstract Aim: To evaluate the subacute effects of the number of Pilates exercise series (one and three) on the cardiovascular responses of medicated hypertensive women. Methods: Eight hypertensive and nine normotensive women underwent a Pilates session with low and high volume, and cardiovascular responses were measured. Aged sample of 50-65 years old underwent to anthropometrical measurements previously to the experimental procedures. The cardiovascular assessment was performed before and after every experimental session. The experimental procedures consisted of two familiarization sessions, load determination, and two experimental sessions (one or three series) for each group. Results: In the intragroup analysis, HR was found to be reduced in the normotensive group. In the hypertensive group, a reduction in the double product was observed after both Pilates sessions, and in the normotensive group only after the session with one series. The volume of exercises of the Pilates method did not interfere in the responses of systolic and diastolic BP after exercise. However, a more prominent area under the curve was seen in the systolic BP of hypertensive subjects who performed three series. Conclusion: The present study shows that performing one or three series of the Pilates exercise does not induce hypotension post-exercise and did not interfere in the cardiovascular responses of medicated hypertensive women.

The relative peak power output of amateur mountain bikers is inversely correlated with body fat but not with fat-free mass

Abstract Aims: To evaluate whether body mass (BM) and body composition may influence mountain bike cycling performance. Methods: Forty male amateur mountain bikers attended the laboratory on two non-consecutive days. At the first visit, anthropometric measures (height, BM, body fat [BF], fat-free mass [FFM] and body mass index [BMI]) and familiarization to incremental cycling test were performed. On the second visit, cyclists performed again the incremental cycling test to measure peak power output (PPO), peak power output relative to BM (PPO-BM), and time to exhaustion (TE), which were posteriorly correlated with BM and anthropometric measures. Results: A low and moderate significant correlation were observed between TE and BM (p<0.01; r=0.40) and FFM (p<0.01; r=0.56). Moderate significant correlation was found between PPO and BM (p<0.01; r=0.45), BMI (p=0.03; r=0.35) and strong with FFM (p<0.01; r=0.59). Also, PPO-BM significantly correlated with BM (p=0.04; r=-0.31), BMI (p=0.02; r=-0.35) and BF (p<0.01; r=-0.55). No other significant correlations were observed. Conclusion: Considering PPO-BM as mainly performance variable, BM and BF can be a determining factor in mountain biking performance but FFM did not.

Blood glucose threshold determination is stage length dependent

Aim: This study aimed to verify whether different stage length affects the intensity of the Blood Glucose Threshold (BGT), and the agreement between evaluators for BGT determination. Methods: Fourteen subjects attended the laboratory during the first session to perform anthropometric measures and become familiar with procedures. In the following three sessions, subjects performed an incremental test on the ergometer bicycle and in each test a different protocol was performed in randomized order (1, 3- and 5-min stage) to identify BGT. Three different evaluators determined the BGT. Results: Our data show that the BGT is stage length-dependent (1, 3- and 5-min; P<0.0001). The intraclass correlation coefficient showed that there was a strong correlation among evaluators for all protocols (ICC = 0.8 to 1 min; ICC = 0.8 to 3 min; and ICC 0.9 to 5 min). However, one evaluator determined the BGT at a higher intensity than others. The peak load was lower at long stage length. Conclusion: We concluded that stage length influences the BGT intensity determination. The BGT presents a good agreement among evaluators. However, a minimum of two evaluators is needed for BGT determination. The peak load is affected by stage length.(AU)
