The cross-cultural adaptation committee was composed of three experts. Our validation sample consisted of 643 athletes from individual and team sports. The results showed clear and relevant content validation and satisfactory internal consistency of the items in the Portuguese version. EFA suggested the exclusion of nine items and the retention of four factors. The CFA analysis with 16 items showed satisfactory adjustment of the model [X²/df = 2.70; CFI = 0.928; TLI = 0.911, RMSEA = 0.05]. The 16-item scale had adequate reliability (> 0.70). It was concluded that the Brazilian version of MSOS showed acceptable psychometric properties.

The efects of aerobic gmnynastics and water gmnynastics in body composition of older women. R. bras. Ci e Mov. 2004; 12(2): 13-18. The purpose of this study was compared and evaluated the effects of aerobic gymnastics and water gymnastics on body composition changes in older women. The sample, composed by 59 women, was splited in three differents roups: two experimental (group 1-aerobic gymnastics, and group 2-water gymnastics) and a control group (group 3). Oriented class was designed for experimnetal groups with three times week, 50 minutes during twelve weeks. The body composition was assessed by Dual Energy X-ray Absorptiometry (DXA) before and after the physical activities treatment. A Split-plot ANOVA (SPANOVA) and a Friedman statistical tests were performed in order to evaluate the following dependent variables: total body weight (kg), total relative body fat, and relative fat from the legs, arms and trunk. After twelve weeks a significant (p < 0,05) impact on body composition was observed in group 1, where there were a reduction in body weight, relative fat from the legs, as well as an increase lean body mass. In group 2 it was observed only a reduction in relative fat from the legs. By these analysis is possible atests that aerobic gymnastics is better than water gymnastics on body composition changes in older women in this study.

Objective: The purpose of this study was to evaluate the priorities that nutritionist and triathletes attributed to food to enhance the sport performance. Method: The sample was composed by 56 subjects, splited in two groups: Nutritionists (G1, n = 29) and Triathletes (G2, n = 27). The Intake Food Priority Question-naire (QPA), composed by food groups, was used to evaluate the importance of each food in the athletic performance. Results: To the data analysis, each food was grouped into one of the eight categories designed in nutrition pyramid. An arithmetic means were elaborated to categories and it was performed t tests for independent samples to compare nutritionists and triathletes priorities about each category. There were no differences between groups in Vegetables, Leguminous, Fruits and Sugar/Candies categories and, also, to the black coffee item. However, the triathletes overestimated the Cereals/Breads/Tubercle and Meat/Eggs categories and underestimated the Milk/Dairy Products and Oils/Fat categories. Conclusion: The triathletes overestimated some macronutrients (carbohydrates and proteins) in detriment from another, like lipids.

Medidas tem surgido e sugerida a reavaliação de outras para identificar o fenômeno do consumo de álcool. Porém, o Alcohol Use Disorders Identification Test (AUDIT) ainda tem sido o instrumento mais utilizado em estudos no mundo, o qual tem se revelado consistente. O presente estudo tem como objetivo avaliar a consistência interna e fatorial do AUDIT em universitários em diferentes estados brasileiros. O AUDIT e dados sociodemográficos foram respondidos por 639 universitários dos dois sexos, acima de 18 anos, distribuídos em diferentes cursos superiores de instituições particulares e públicas em quatro estados no Brasil. Realizando distintos cálculos estatísticos, observaram-se indicadores psicométricos que revelaram confiabilidade na medida do AUDIT na amostra pesquisad...

Resistance training (RT) is effective in controlling glycemia and lipemia in kidney disease; however, the effect of RT with blood flow restriction (RT+BFR) on these metabolic factors has not been investigated. We aimed to verify if chronic (6 months) RT and RT+BFR performed by patients with stage-2 chronic kidney disease (CKD) improves their glycemic homeostasis and immunometabolic profiles. Patients with CKD under conservative treatment (n = 105 (33 females)) from both sexes were randomized into control (n = 35 (11 females); age 57.6 ± 5.2 years), RT (n = 35 (12 females); age 58.0 ± 6.2 years), and RT+BFR (n = 35 (10 females); 58.0 ± 6.4 years) groups. Chronic RT or RT+BFR (6 months) was performed 3 times per week on non-consecutive days with training loading adjusted every 2 months, RT 50%–60%–70% of 1RM, and RT+BFR 30%–40%+50% of 1RM and fixed repetition number.

Therefore, training volume is an important variable related to these neuromuscular adaptations (American College of Sports, 2009). During a resistance exercise (RE) session the number of repetitions performed by a subject is influenced by the inter-set rest intervals (Ratamess et al., 2012; Tibana et al., 2012). In untrained subjects the rest interval between sets should be sufficient to promote an adequate bioenergetic recovery, facilitate the removal of metabolic waste products, and provide for the reestablishment of force production (Willardson, 2006).Previous studies revealed that shorter rest intervals between sets and exercises (1- versus 3- or 5-min) elicit a more pronounced metabolic (Farinatti & Castinheiras Neto, 2011; Ratamess et al., 2007), hormonal (Bottaro et al., 2009), and cardiovascular stress (de Salle...

Considering a recursive structural equation model, it showed that the socio-normative peers were associated positively to the cultural attributes of collectivism and instructive leisure habits, and these were negatively associated with deviant behaviors. Moreover, the socio-normative pairs were negatively related with the cultural attributes of individualism and hedonistic pleasure, the latter related positively to deviant behavior.

Can resistance training with and without blood flow restriction improve redox balance and positively impact the autonomic cardiac modulation in chronic kidney disease patients? What is the main finding and its importance? Resistance training with and without blood flow restriction improved antioxidant defence (paraoxonase 1), decreased the pro‐oxidative myeloperoxidase, improved cardiac autonomic function and slowed the decrease in renal function. We draw attention to the important clinical implications for the management of redox balance and autonomic cardiac function in chronic kidney disease patients.

Brain-derived neurotrophic factor (BDNF) levels are negatively associated with depressive symptoms and decrease during a single hemodialysis session. Resistance training (RT) might be an additional non-pharmacological tool to increase BDNF and promote mental health. Methods: Two randomized groups of hemodialysis patients: control (CTL, n = 76/F36; 66.33 ± 3.88 years) and RT (n = 81/F35; 67.27 ± 3.24 years). RT completed six months of training thrice a week under the supervision of strength and conditioning professional immediately before the dialysis session. Training loads were adjusted using the OMNI rating of perceived exertion. The total antioxidant capacity (TROLOX), glutathione (GSH), thiobarbituric acid reactive substance (TBARS), and BDNF levels were analyzed in serum samples. Quality of life (assessed through Medical Outcomes—SF36), and Beck Depression Inventory was applied. Results: RT improved handg...

A amostra foi constituida por 42 mulheres idosas ativas com idade media igual a 68,8 (± 6,0) anos, estatura 1,53 (± 5,8) metros e massa corporal 65,8 (± 9,9) Kg. Estas foram subdivididas em 3 grupos segundo o perfil psicologico de genero, sendo o Grupo 1 - Heteroesquematicas Masculinas (n= 11), Grupo 2 - Isoesquematicas (n= 13) e Grupo 3 (Heteroesquematicas Femininas (n= 18). Para a avaliacao de forca muscular de membros inferiores, foi utilizado o dinamometro isocinetico da marca Biodex 3 System Pro® (Biodex Biomedical Systems, Inc., Shirley, NY). Foram analisados o pico de torque (PT), a potencia (POT), o trabalho total (TT) e a razao I/Q de extensores e flexores de joelho dominante e nao dominante, no modo isocinetico, nas velocidades de 6...

Considering a recursive structural equation model, it showed that the socio-normative peers were associated positively to the cultural attributes of collectivism and instructive leisure habits, and these were negatively associated with deviant behaviors. Moreover, the socio-normative pairs were negatively related with the cultural attributes of individualism and hedonistic pleasure, the latter related positively to deviant behavior.

The research of an exploratory qualitative approach performed with 21 aged from 60 years, members of the Coral "Sempre Jovem (Forever Young)", the Open University of the Third Age (Universidade Aberta da Terceira Idade - UnATI) Catholic University of Brasilia (Universidade Catolica de Brasilia - UCB-DF). Semi-structured interviews, questionnaire and socioeconomic Rosenberg Self-Esteem Scale (RAS) were conducted. The analysis procedures included: content analysis / thematic analysis, transcription and categorization of interviews and calculating the overall score of the EAR. In EAR, subjects older than 6 months had a higher percentage of self-esteem than the Starter (less than 6 months), 76% and 72.3% respectively. The elderly women have more time to participate maintained a higher standard homogeneous self-est...

Para tanto, participaram da amostra 444 mulheres brasileiras participantes de Jogos Olímpicos até Londres em 2012. Dos relatos de vida, foram retirados dados relacionados aos objetivos deste estudo. Os resultados nos permitem inferir que modalidades como natação, ginástica e tênis o início foi muito precoce, já nos esportes coletivos a idade de início corresponde a fase escolar, quando neste momento o profissional de Educação Física é o principal responsável pela iniciação ao rendimento. Esportes como tiro, arco, boxe e levantamento de peso tem seu início já no final da adolescência. Com relação ao final de carreira, a faixa etária de aposentadoria corresponde com a modalidade, onde aqueles esportes que se começa cedo as idades de aposentadoria são menores. Observou-se também que os motivos principais par...

Can resistance training with and without blood flow restriction improve redox balance and positively impact the autonomic cardiac modulation in chronic kidney disease patients? What is the main finding and its importance? Resistance training with and without blood flow restriction improved antioxidant defence (paraoxonase 1), decreased the pro‐oxidative myeloperoxidase, improved cardiac autonomic function and slowed the decrease in renal function. We draw attention to the important clinical implications for the management of redox balance and autonomic cardiac function in chronic kidney disease patients.

Brain-derived neurotrophic factor (BDNF) levels are negatively associated with depressive symptoms and decrease during a single hemodialysis session. Resistance training (RT) might be an additional non-pharmacological tool to increase BDNF and promote mental health. Methods: Two randomized groups of hemodialysis patients: control (CTL, n = 76/F36; 66.33 ± 3.88 years) and RT (n = 81/F35; 67.27 ± 3.24 years). RT completed six months of training thrice a week under the supervision of strength and conditioning professional immediately before the dialysis session. Training loads were adjusted using the OMNI rating of perceived exertion. The total antioxidant capacity (TROLOX), glutathione (GSH), thiobarbituric acid reactive substance (TBARS), and BDNF levels were analyzed in serum samples. Quality of life (assessed through Medical Outcomes—SF36), and Beck Depression Inventory was applied. Results: RT improved handg...
