RESUMO

BACKGROUND: The aim of this study was to compare cell integrity indicators according to the playing position in university indoor football athletes. METHODS: The sample consisted of 34 university athletes (20 female and 14 male). Dependent variables were cell integrity indicators: total body water (TBW), intracellular water (ICW), extracellular water (ECW), ECW/ICW ratio, body cell mass (BCM), ECW/BCM ratio, phase angle (PhA), resistance (R), Xc (reactance) and impedance (Z), evaluated by the electrical bioimpedance method. Independent variable was the playing position: goalkeeper (a), defender (a), winger (left and right) and pivot collected through questionnaire. Control variables were age, time of sport practice, participation in competitions per year and training load obtained by applying the anamnesis form, and body fat and fat and bone-free mass were obtained through dual emission X-ray absorptiometry (DXA). Covariance analysis (ANCOVA) was used, with post-roc Tukey's test, to identify difference between groups, with p <0.05. RESULTS: In the adjusted analysis, female athletes in the defense position had BCM values (31.1 ±2.1) higher than those in the wing position (25.8 ±1.1) (p <0.01). In males, pivots showed higher ICW values (31.47 ±0.77) when compared to defenders (25.7 ±0.8) (p = 0.02). In addition, goalkeepers had higher TBW values (52.7 ±2.5) compared to wingers (42.3 ±1.2) (p = 0.03). CONCLUSIONS: Cell integrity indicators may vary according to the playing position in indoor football.

RESUMO

BACKGROUND: Bioelectrical impedance vector analysis (BIVA) is able to identify differences in hydration status and body composition components, such as body cell mass (BCM) by means of plotting individuals in ellipses, when comparing groups with different characteristics. OBJECTIVE: Compare the confidence and tolerance ellipses of BIVA in individual and team sports athletes with a non-athlete reference population. DESIGN AND PARTICIPANTS: One hundred sixty-seven college athletes (team sports: 117 athletes, individual sports: 50 athletes) aged between 18 and 35 years. Bioelectrical impedance was used to measure resistance (R) and reactance (Xc) values that were used in the BIVA analysis to identify hydration status and BCM, respectively. Hotelling's t-test was used to identify differences between groups in the confidence ellipses and the comparison was made with a non-athlete Italian reference population. RESULTS: There were no differences between male team sports and individual athletes (p = 0.151) and for female athletes (p = 0.624). Most athletes were located in the 50% tolerance ellipses, indicating adequate hydration. Compared to the Italian a non-athlete population, athletes of both sexes presented left impedance vector deviation in the minor axis (Xc) of the tolerance ellipses, indicating higher BCM. CONCLUSION: There were no differences in BIVA between team and individual sports athletes, but most athletes presented an adequate hydration state and, compared to a non-athlete population, the athletes of the present study presented higher BCM.

RESUMO

ABSTRACT Introduction: Physical exercise has been considered an important non-pharmacological treatment for reducing tiredness, pain, low self-esteem and increases in body mass in individuals diagnosed with cancer. Objective: To verify the relationship between fatigue, quality of life and levels of physical activity in cancer patients undergoing chemotherapy. Methods: Observational, cross-sectional study. The sample consisted of 85 adult patients undergoing cancer treatment at a university hospital. Physical activity was assessed by the IPAQ, and fatigue and quality of life by the PFS and EORTC QLQ-C30 questionnaires, respectively. Student's t and the Fisher's Exact tests were used to identify differences between active and physically inactive patients for the variables fatigue and quality. Additionally, covariance analysis (ANCOVA) was used, in which simple (outcome and exposure) and adjusted models (age, time of diagnosis and type of cancer) were tested. Results: The study included 85 cancer patients, with a mean of 51.78 years of age (±11.72). Most were female and not physically active. Patients classified as physically inactive had higher scores for "total fatigue" (p=0.01), "behavioral" (p=0.01), "affective" (p=0.02) and psychological/sensory fatigue (p=0.04), compared to the physically active patients (p=0.01). Patients classified as physically not very active presented poorer quality of life in the dimensions: "overall" quality of life (p=0.05) and "functional" (p=0.04), "appetite" (p=0.02), "insomnia" (p=0.0 2), "diarrhea" (p=0.04), "fatigue" (p=0.01), "pain" (p=0.01) and "nausea" (p=0.03), when compared to the physically active patients in both analyses; simple and adjusted. Conclusion: The practice of physical activity during treatment can be a determining factor for increasing quality of life and reducing fatigue in cancer patients, minimizing the adverse effects of chemotherapy. Level of evidence II; retrospective study.


RESUMO Introdução: O exercício físico tem sido considerado um importante tratamento não farmacológico para diminuir a sensação de cansaço, as dores, a baixa autoestima e o aumento da massa corporal em indivíduos com diagnóstico de câncer. Objetivo: Verificar a relação entre fadiga, qualidade de vida e níveis de atividade física em pacientes oncológicos submetidos à quimioterapia. Métodos: Estudo observacional, transversal. A amostra foi composta por 85 pacientes adultos em tratamento oncológico em hospital universitário. A atividade física foi avaliada pelo IPAQ, a fadiga e a qualidade de vida, pelos questionários PFS e EORTC QLQ-C30, respectivamente. Foram empregados os testes t de Student e Exato de Fisher para identificar diferenças entre os pacientes fisicamente ativos e pouco ativos para as variáveis de fadiga e qualidade de vida. Adicionalmente, foi empregada a análise de covariância (ANCOVA) em que foram testados modelos simples (desfecho e exposição) e ajustados (idade, tempo de diagnóstico e tipo de câncer). Resultados: Participaram do estudo 85 pacientes com câncer e média de 51,78 anos de idade (± 11,72). A maioria era do sexo feminino e pouco ativa fisicamente. Pacientes classificados como fisicamente pouco ativos apresentaram maiores escores de "fadiga total" (p = 0,01), "comportamental" (p = 0,01), "afetiva" (p = 0,02) e fadiga psicológica/sensorial (p = 0,04), em comparação com pacientes fisicamente ativos (p=0,01). Os pacientes classificados como fisicamente pouco ativos tinham pior qualidade de vida nas dimensões: qualidade de vida "geral" (p = 0,05) e "funcional" (p = 0,04), "apetite" (p = 0,02), "insônia" (p = 0,02), "diarreia" (p = 0,04), "fadiga" (p = 0,01), "dor" (p = 0,01) e "náuseas" (p = 0,03) quando comparados com os pacientes fisicamente ativos, em ambas as análises, simples e ajustada. Conclusão: A prática da atividade física durante o tratamento pode ser um fator determinante para aumentar a qualidade de vida e reduzir a fadiga em pacientes com câncer, minimizando os efeitos adversos da quimioterapia. Nível de Evidência II; Estudo retrospectivo.

RESUMO

The aim of this systematic review was to identify and summarize evidence for the association between muscle strength (MS) and metabolic syndrome (MetS), and MS and combinations of risk factors for MetS in children and adolescents. Five databases (Medline/PubMed, EBSCO, Scielo, Scopus, and Web of Knowledge) were searched up to November 2019 with complementary reference list searches. Inclusion criteria were studies that investigated the relationship between MS and MetS or MS and combinations of risk factors for MetS in children and adolescents (≤19 years of age). Risk of bias was assessed using standard procedures. From the total of 15,599 articles initially identified, 13 articles were included, representing 11,641 children and adolescents. Higher MS values were associated with lower risk for MetS or combinations of risk factors for MetS (n=11/13 studies). Of the total of included studies, about 23.1% (03/13) were longitudinal and all included studies were classified as having a moderate risk of bias. This review provides preliminary evidence for a beneficial relationship between MS and MetS among children and adolescents. Additionally, although the body of evidence points to the beneficial relationship between higher MS and lower risk for combination of factors for MetS in children and adolescents, this relationship is inconclusive.

RESUMO

OBJECTIVE: The purpose of this study was to identify and summarize the relationships between MS and individual components of metabolic syndrome (MetS) [high waist circumference (WC), high blood pressure (BP), high systolic blood pressure (SBP), high diastolic blood pressure (DBP), high triglycerides (TG), fasting blood glucose (GL) and low HDL cholesterol levels (HDL-C)] in adults. METHODS: A systematic review was performed on six electronic databases (Lilacs, Pubmed, Scielo, Scopus, Sportdiscus, and Web of Knowledge), with complimentary searches in reference lists. The databases were investigated without restrictions regarding the period of publication. RESULTS: Of the 6,833 articles initially identified, 17 were included, with data on 43,343 adults. Higher MS values were associated with lower WC values. Different results in relation to the association between MS and BP, MS and SBP, and MS and DBP were verified. In addition, inconclusive results were verified in the relationship between MS and TG, MS and HDL-C, and MS and GL. CONCLUSION: Higher MS values were related with lower WC in adults. More evidence from longitudinal studies with high methodological rigor is needed to elucidate the relationship between MS and CVD among adults.

RESUMO

BACKGROUND: Bus drivers are exposed to unique working conditions. The behavioral and health trends of these workers should be investigated. OBJECTIVE: To estimate the prevalence of abdominal obesity and associated lifestyle factors in bus drivers in a city in Southern Brazil. METHODS: A cross-sectional study with 103 bus drivers with mean age of 41 years (±8.5) was conducted. Abdominal obesity was measured through waist circumference using anthropometric tape. To evaluate the different lifestyle domains, the Brazilian version of the Canadian Fantastic Lifestyle questionnaire was used. To check the association between abdominal obesity and lifestyle, binary logistic regression was used, with odds ratio (OR) estimates and 95% confidence intervals (95% CI). RESULTS: It was verified that 26.3% of drivers had abdominal obesity. In addition, bus drivers who had inadequate lifestyle in the "Nutrition" and "Type of behavior" domains were, respectively, 3.6 (95% CI: 1.3-9.5, p = 0.01) and 2.6 times (95% CI: 1.1-6.7; p = 0.04) more likely of having abdominal obesity when compared to those adequate in these lifestyle domains. CONCLUSIONS: Approximately one in four drivers had abdominal obesity and the "Nutrition" and "Type of Behavior" domains were associated with abdominal obesity.

RESUMO

INTRODUCTION: Bioelectrical impedance analysis (BIA) has been used to evaluate cellular health and integrity through bioelectrical indicators. In the sporting context, monitoring these indicators can be useful to assess the quality and vitality of cells and body tissues. OBJECTIVE: The aim of this systematic review was to investigate indicators of cellular health and integrity evaluated by BIA in athletes. METHODS: Searches were performed in December 2017 in the Lilacs, Medline, PubMed, Science Direct, Scielo, Scopus, SPORTDiscus, and Web of Science databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: The searches retrieved 31 articles (30 involving professional athletes and one involving university athletes). In longitudinal studies (n = 15), the bioelectrical parameters directly associated with cellular health and integrity were extracellular water (ECW), phase angle (PA), BIA vector analysis (BIVA), crude reactance data (Xc), resistance (R), and ECW/BCM ratio. Regarding the findings of cross-sectional studies (n = 16), the investigated parameters (ECW, PA, BIVA, Z, BCM, and ECW/BCM) were directly associated with gender, age, sports performance level, modality, and game position. CONCLUSIONS: In the included studies, the cellular health and integrity indicators were: Z, Xc, R, total water, intracellular water, ECW, PA, BIVA, BCM, and ECW/BCM.

RESUMO

OBJECTIVE: Examine association between phase angle and isolated and grouped physical fitness indicators in adolescents. METHODS: The sample consisted of 353 adolescents, aged 10-16 years. Phase angle was calculated based on crude resistance and reactance values (50 kHz frequency) obtained by tetrapole electrical bioimpedance (BIA). Fat mass and lean mass were estimated by means of anthropometric equations. Hydraulic dynamometer was used to measure handgrip strength and aerobic fitness was obtained by means of the 20-m back-and-forth test. The z-score for isolated and grouped physical fitness indicators was calculated. Covariates were age, habitual physical activity and screen time (obtained by questionnaire), and sexual maturation (self-reported). RESULTS: For males, phase angle was directly associated with lean mass (ß = 0.02, p < 0.01), handgrip strength (ß = 0.03, p < 0.01), and aerobic fitness (ß = 0.01, p = 0.05), even adjusting for covariates. For females, phase angle was directly associated with lean mass (ß = 0.02; p = 0.04) after adjusting for covariates. Phase angle was directly associated with composite physical fitness z-score in both sexes (male, ß = 0.09, p < 0.01, female, ß = 0.03, p = 0.05), even adjusting for covariates. CONCLUSIONS: Phase angle was directly associated with isolated and grouped physical fitness indicators in adolescents. In this way, the phase angle can be used to monitor the health of adolescents.

RESUMO

Rodrigues de Lima, T, Custódio Martins, P, Henrique Guerra, P, and Augusto Santos Silva, D. Muscular fitness and cardiovascular risk factors in children and adolescents: A systematic review. J Strength Cond Res 34(8): 2394-2406, 2020-The purpose of this study was to identify and summarize the relationships between muscular fitness (MF) and individual components of metabolic syndrome (high waist circumference [WC], high blood pressure [BP], high systolic BP [SBP], high diastolic BP [DBP], high triglycerides [TG], fasting blood glucose [FG], and low HDL cholesterol levels [HDL-C]) in children and adolescents. A systematic review was conducted in 5 electronic databases, with complementary searches in reference lists, and the inclusion criteria were children and adolescents (age group up to 19 years of age) with no special clinical conditions. In all articles, risk of bias was analyzed by a standardized instrument. Of the 5,973 articles initially identified, 21 were included, with data on 22,261 children and adolescents. Higher MF values were associated with lower TG (n = 07) and WC values (n = 15). Different results in relation to the relationship between MF and SBP (n = 10) and MF and DBP (n = 07) were verified. In addition, there was no relationship between MF and FG (n = 06). In addition, inconclusive results were verified in the relationship between MF and HDL-C (n = 07). Concluded higher MF values were related to lower WC values and lower TG concentrations.

RESUMO

Aim: This study assessed whether the presence of malocclusion had a negative impact on the oral health-related quality of life (OHRQoL) of eight to ten-year-old children of low socioeconomic status. Methods: A cross-sectional study was conducted with a total of 111 children, eight to ten years of age, randomly selected from public schools from Diamantina, MG, Brazil. The number of children was determined by a sample size calculation. Two calibrated examiners performed clinical oral examinations for the diagnosis of malocclusion, dental caries experience, and traumatic dental injuries following the Dental Aesthetic Index (DAI), the World Health Organization (WHO), and Andreasen's classification, respectively. The Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) was applied to evaluate the OHRQoL. Descriptive and bivariate (p < 0.05) analyses were also performed. Results: Children had a mean age of 8.89 ± 0.82 years, of which 52.3% were female. The prevalence of malocclusion was 62.2%. Significant differences were found in emotional (p = 0.045) and social (p = 0.017) well-being subscale scores as well as in the total CPQ8-10 (p = 0.022) scores between children with and without malocclusion. Conclusion: The presence of malocclusion negatively impacted the OHRQoL of children aged eight to ten years of age of a low socioeconomic status.

RESUMO

Abstract Aims: The objective was to estimate the prevalence and the factors of behaviors of provocation and control of the weight associated with dissatisfaction with the body image among adolescents. Methods: Cross-sectional study with 580 adolescents (11 to 17 years old) from Criciúma, Brazil. The body image was evaluated by the silhouettes scale and the behaviors of provocation and weight control by questionnaires. A multinomial logistic regression was used (p ≤ 0.05). Results: Of the total number of adolescents, 48.6% were dissatisfied with being overweight (male 47.9%, female 49.3%) and 22.9% dissatisfied with thinness (male 23.8%, female 22.1%). Male adolescents who were dissatisfied with being overweight were more likely to be joked and laughed at because of their appearance and lower chances of being nicknames due to their size or body weight, while those who were unsatisfied with being thin were more likely to joke and laughter because of the appearance, compared to satisfied. Female adolescents who were dissatisfied with being overweight were more likely to be laughed at because they were uncoordinated and without food for 24 h, while those who were unsatisfied with being thin were less likely to be joking and laughing because of their appearance and higher chances to be the targets of laughter because they are uncoordinated, compared to those that are satisfied. Conclusion: The dissatisfaction with body image was associated with different behaviors of provocation and weight control according to sex.

RESUMO

Neste artigo, buscou-se compreender a concepção de Educação para C. G. Jung e suas possíveis contribuições para o processo educativo, principalmente no tocante à sua teoria dos tipos psicológicos. Embora tenham sido orientados para o trabalho psicoterapêutico, os resultados apontaram que a Psicologia Analítica traz pressupostos relevantes que podem ser aplicados à educação. Os resultados, também, demonstraram a importância da escola na formação da consciência individual, por ser o primeiro espaço que a criança frequenta fora do ambiente familiar. O processo transferencial e as interferências dos conteúdos inconscientes envolvidos na relação educador-aluno sugere a necessidade de atuação sobre a personalidade do educador, no sentido de desenvolver não somente o aspecto cognitivo, mas, principalmente, a afetividade e a sensibilidade, a fim de evitar influências negativas na transmissão do conhecimento. A teoria dos tipos psicológicos contribui para pensar as diferenças individuais, ao considerar as variadas formas de cognição, adaptação e percepção do mundo.


In this article, we try to understand the conception of Education for C. G. Jung and his possible contributions to the educational process, especially his theory about psychological types. The results pointed out, although it was oriented to psychotherapeutic work, Analytical Psychology provides relevant assumptions that can be applied to education. The results demonstrated the importance of the school in the formation of individual consciousness, since it is the first space that the child attends outside the family environment. The transfer process and the interferences of the unconscious contents involved in the educator-student relationship suggest the need to act on the personality of the educator, seeking to develop not only the cognitive aspect, but mainly the affectivity and sensitivity, in order to avoid influences in the transmission of the knowledge. The theory of psychological types contributes to the thinking of individual differences, considering the different forms of cognition, adaptation and perception of the world.

RESUMO

Analisar a relação entre autoeficácia e estratégias de enfrentamento em usuários abstinentes de drogas. Estudo descritivo, correlacional, com abordagem quantitativa, de campo e transversal. Aplicaram-se a Escala de Autoeficácia para Abstinência de Drogas, o Inventário de Habilidades de Enfrentamento Antecipatório para a Abstinência de Álcool e outras Drogas e um Questionário Sociodemográfico. Participaram 100 homens. Evidenciou-se que a crença de ser autoeficaz diante das emoções negativas obteve correlação positiva e significativa ao ser Assertivo na Recusa de Drogas, no Autocontrole de Emoções e na Expressão de Emoções Positivas. Já ser Assertivo na Recusa de Drogas apresentou correlação positiva e significativa com a crença de ser eficaz frente a Emoções Negativas, Situações Sociais Positivas, Preocupações com outros, e estados fisiológicos como a Síndrome de Abstinência ou Fissura. Tais relações demonstram a necessidade da utilização destes fenômenos quando se busca a abstinência de usuários de drogas.


To analyze the relationship between self-efficaciousness and coping strategies in drug-abstaining people. Descriptive, co-relational, quantitative, transversal field study. Auto-efficaciousness Scale for Drug Abstinence, Inventory of Anticipatory Coping Abilities for Alcohol and Drug Abstinence and a Socio-demographic Questionnaire, with one hundred males. Belief in auto-efficaciousness with negative emotions had a positive and significant co-relationship with regard to Assertion in Drug Refusal, Self-control in Emotions and in Expression of Positive Emotions. Assertion in Drug Refusal had a positive and significant co-relationship with belief in efficiency to cope with Negative Emotions, Positive Social Situations, Concern for Others, and physiological states such as Abstinence Syndrome or Fissure. Relationships demonstrated the need for these phenomena when drug users seek abstinence.

RESUMO

ABSTRACT Objective: To identify sociodemographic, physical activity, and physical fitness factors associated with flexibility. Methods: Cross-sectional study with 909 adolescents (486 girls) aged 14 to 19 years from the city of São José, Santa Catarina, Brazil. To evaluate flexibility, we used the sit and reach test. Sociodemographic and physical activity data were collected by a self-administered questionnaire. We analyzed muscle strength with manual dynamometry. Aerobic fitness was assessed with the modified Canadian aerobic fitness test, and physical activity with a questionnaire. We used multiple linear regression to identify the variables associated with flexibility, with a significance level of 5%. Results: For each additional centimeter in the girls' levels of flexibility, the boys were 2.94 cm less flexible. In addition, the increment of 0.12 kg/force in muscle strength levels increased the levels of flexibility in 1 cm. Conclusions: Lower levels of flexibility were associated with male adolescents and with reduced strength levels.


RESMO Objetivo: Identificar os fatores sociodemográficos, de atividade física e da aptidão física associados à flexibilidade. Métodos: Estudo transversal com 909 adolescentes (486 meninas) de 14 a 19 anos da cidade de São José, Santa Catarina, Brasil. A flexibilidade foi avaliada por meio do teste de sentar e alcançar. Os dados sociodemográficos e de atividade física foram levantados por meio de questionário autoadministrado. A força muscular foi analisada por meio da dinamometria manual. A aptidão aeróbia foi analisada por meio do teste canadense modificado de aptidão aeróbia, enquanto a atividade física foi avaliada por questionário. Utilizou-se regressão linear múltipla para identificar as variáveis associadas à flexibilidade, com nível de significância de 5%. Resultados: Verificou-se que a cada centímetro a mais nos níveis de flexibilidade nas meninas, os meninos tiveram 2,94 cm a menos de flexibilidade. Ademais, o incremento de 0,12 kg/força nos níveis de força muscular aumentou em 1 cm os níveis de flexibilidade. Conclusões: Menores níveis de flexibilidade estiveram associados aos adolescentes do sexo masculino. Além disso, menores níveis de flexibilidade foram diretamente associados aos adolescentes que apresentavam menores níveis de força.

RESUMO

PURPOSE: To examine the capacity of physiological variables and performance to predict peak oxygen consumption (peak V˙ O2) in children and adolescents living with HIV. METHOD: Sixty-five children and adolescents living with HIV (30 boys) aged 8-15 years, participated in the study. Peak V˙ O2 was measured by breath-by-breath respiratory exchange during an incremental cycle ergometer until volitional exhaustion. Information on the time to exhaustion, maximal power output (Pmax), and peak heart rate (peak HR) were also recorded. RESULTS: Predictive models were developed and all equations showed the ability of performance variables to predict peak V˙ O2. However, Model 1 was based only on Pmax by following equation: Y = 338.8302 + (Pmax [W] * 11.16435), R2 = 0.90 and standard error of estimation (SEE) = 180 ml ⋅ min-1. CONCLUSION: The V˙ O2 peak can be predicted simply by the Pmax obtained from the incremental cycle ergometer test. This protocol is a valid and useful tool for monitoring the aerobic fitness of children and adolescents living with HIV, especially in resource-limited settings.

RESUMO

The objective of this study was to identify the association of phase angle with physical fitness in children and adolescents infected with HIV. Sixty-four children and adolescents infected with HIV (8-15 years old) were tested for vertical transmission. The electrical bioimpedance was used to obtain the phase angle. Body fat (BF) and lean soft tissue mass (LSTM) were measured by x-ray absorptiometry, and the manual grip strength was evaluated by dynamometry. The peak oxygen consumption (VO2 peak) was measured by respiratory change in a submaximal incremental test. Moderate-vigorous physical activity (MVP) and sedentary behavior were measured using accelerometers and were used as covariates. Multiple linear regression was used. The linear correlation analyses demonstrated that the phase angle was inversely proportional to relative BF (r = -0.26), but was not associated with absolute body fat (r = -0.02). The phase angle was directly associated with LSTM (r = 0.57), handgrip strength, and (r = 0.43) peak VO2 (r = 0.55). The phase angle was not associated with absolute BF (ß = -0.017, P = 0.413) and relative (ß = -0.014, P = 0.175). The phase angle presented a direct association with LSTM (ß = 0.041, P = 0.019) and peak VO2 (ß = 0.005; P = 0.019), regardless of age, sex, sexual maturation, MVPA, sedentary behavior, antiretroviral drugs, and viral load. No association was found between phase angle and handgrip strength (ß = 0.153; P = 0.199). It was concluded that phase angle was associated with LSTM and the aerobic fitness in HIV-infected children and adolescents.

RESUMO

Chicken meat and eggs are important sources of food for the world population. The significant increase in food demand has pushed the food industry toward a rapid non-expensive production which in turn raises ethical issues. How chicken are cultivated and processed in food industry is no longer acceptable. Ethical and economical concerns emerging from chicken culling need to be solved in the near future. Indeed, in egg production industry, male chicken are killed at the age of 1-day post-hatching since they are not egg producers. A number of laboratory all over the world are looking for innovative non-invasive sexing methods to determine the sex of chicken in the early stages of the development before hatching. It will allow males' chicken elimination before the pain-feeling stages. In order to evaluate the efficiency of these methods, the scientific community need a reliable, easy to use and cost-effective in-ovo invasive sexing method. In this report, we developed two new invasive assays based on PCR and Q-PCR techniques respectively, which fulfil the above mentioned requirements. In the same line with other groups, we exploited the differences betweed males (ZZ) and females (ZW) chicken sexual chromosomes. We identified two genes, SWIM and Xho-I, on chromosome W and DMRT gene on chromosome Z allowing a clear discrimination between the two sexes using PCR and qPCR respectively. These two new genomic markers and their corresponding methods not only increase the accuracy but also reduce time and cost of the test compared to previously developed sexing methods. Depending on the technology available in the lab, one can choose between the two techniques requiring different machines and expertise.

RESUMO

OBJECTIVE: To identify sociodemographic, physical activity, and physical fitness factors associated with flexibility. METHODS: Cross-sectional study with 909 adolescents (486 girls) aged 14 to 19 years from the city of São José, Santa Catarina, Brazil. To evaluate flexibility, we used the sit and reach test. Sociodemographic and physical activity data were collected by a self-administered questionnaire. We analyzed muscle strength with manual dynamometry. Aerobic fitness was assessed with the modified Canadian aerobic fitness test, and physical activity with a questionnaire. We used multiple linear regression to identify the variables associated with flexibility, with a significance level of 5%. RESULTS: For each additional centimeter in the girls' levels of flexibility, the boys were 2.94 cm less flexible. In addition, the increment of 0.12 kg/force in muscle strength levels increased the levels of flexibility in 1 cm. CONCLUSIONS: Lower levels of flexibility were associated with male adolescents and with reduced strength levels.

RESUMO

OBJECTIVE: To compare indicators of fluid distribution and cellular integrity in university athletes through a cross-sectional study of 167 university athletes (18-35 years) who competed in team sports and individual sports. APPROACH: Bioimpedance was used to estimate total body water (TBW), intracellular water (ICW), extracellular water (ECW), ECW/ICW ratio, impedance (Z), reactance (Xc), resistance (R), phase angle, body cell mass (BCM) and ECW/BCM ratio at a frequency of 50 kHz. X-ray absorptiometry was used to determine lean soft tissue mass and body fat. As covariables, sex, age, time of practice and type of modality were obtained by questionnaire. MAIN RESULTS: Individual male athletes presented higher values of ECW/ICW ratio (means difference MD = 0.006, p  = 0.020) and ECW/BCM ratio (MD = 0.006, p  = 0.017) than team sports male athletes. Values of Z (MD = 24.988, p  = 0.009), Xc (MD = 3.327, p  = 0.008) and R (MD = 24.755, p  = 0.09) were higher in male athletes practicing team sports than individual sports. Female team sports athletes presented higher values of Z (MD = 32.029, p  = 0.015) and R (MD = 31.987, p  = 0.015) than individual female athletes. It was concluded that ECW/ICW and ECW/BCM ratios were higher in male athletes who practiced individual sports. For the Z, R, and Xc values, the athletes in team sports presented higher values. The female athletes who practiced team sports presented higher values of Z and R than did individual female athletes. SIGNIFICANCE: ECW/ICW and ECW/BCM ratios were higher in male athletes who practiced individual sports. For the Z, R, and Xc values, the athletes in team sports presented higher values. The female athletes who practiced team sports presented higher values of Z and R than did individual female athletes.

RESUMO

ABSTRACT Introduction: Fecal incontinence is the involuntary loss of stools and gases, characterized by the inability to keep physiological control of bowel contents. It can negatively affect patients' quality of life. Biofeedback is a therapeutic tool used in the treatment, through the training of the pelvic floor muscles from visual and sound stimuli. Objective: To evaluate the effects of biofeedback in the treatment of female fecal incontinence. Methods: Twenty-three patients with fecal incontinence, diagnosed by clinical evaluation and manometry, and referred for biofeedback treatment, participated responding to the Cleveland Clinic Incontinence Assessment scale, and the Fecal Incontinence Quality of Life Questionnaire to obtain personal data, clinical complaints and incontinence characteristics. Four biofeedback sessions were held once a week. After the protocol, they were reevaluated with anorectal manometry and questionnaires, and they were instructed to daily perform the sphincteric contraction exercises at home. Results: The comparison of the Cleveland Clinic Florida Scoring System and FIQL scores before and after the biofeedback protocol showed a significant decrease (p = 0.0001) in fecal incontinence. The mean anal pressure at rest was 33.3 mmHg before and 49.65 mmHg after biofeedback, while the mean anal pressure of maximal voluntary contraction was 85 mmHg before treatment and 136.65 mmHg after it. Conclusion: Biofeedback is an effective method for the treatment of fecal incontinence, with increased sphincter strength and improved quality of life.


RESUMO Introdução: A incontinência anal é a perda involuntária de fezes e gases, caracterizada pela incapacidade de manter o controle fisiológico do conteúdo intestinal. Pode interferir negativamente na qualidade de vida dos pacientes. Biofeedback é uma ferramenta terapêutica utilizada no tratamento, através do treinamento dos músculos do assoalho pélvico, a partir de estímulo visual e sonoro. Objetivo: Avaliar os efeitos do biofeedback no tratamento da incontinência anal feminina. Metódos: Participaram 23 pacientes portadoras de incontinência anal, diagnosticadas pela avaliação clínica, manométrica e encaminhadas para tratamento com biofeedback, responderam um questionário para obtenção dos dados pessoais, queixas clínicas e características da incontinência, a escala de Avaliação da Incontinência da Cleveland Clinic e o questionário Fecal Incontinence Quality of life. Foram realizadas quatro sessões de biofeedback, uma vez por semana. Após o protocolo foram novamente reavaliadas com exame de manometria anorretal e questionários, foram orientadas a realizar os exercícios de contração esfincteriana diariamente em casa. Resultados: Na comparação dos escores dos questionários Cleveland Clinic Florida Scoring System e FIQL antes e após o protocolo de biofeedback pode-se observar diminuição significativa (p = 0,0001) da incontinência anal. As medias de pressão anal de repouso foi de 33,3 mmHg antes e 49,65 mmHg após o biofeedback, enquanto que a média da pressão anal de contração voluntária máxima foi de 85 mmHg antes do tratamento e 136,65 mmHg após o mesmo. Conclusão: O biofeedback é um método efetivo no tratamento da Incontinência anal, com aumento da força esfincteriana e melhora da qualidade de vida.
