Neste trabalho, apresentamos a análise da abrangência pessoal dos recursos para a indeterminação do agente em língua portuguesa, ou seja, das pessoas - 1ª, 2ª, 3ª - envolvidas por tais recursos. Para a seleção dos recursos abordados, consideramos, inicialmente, as noções de indeterminação e agente; em seguida, tendo em vista o objetivo proposto, passamos a descrevê-los, especificando os fatores que concorrem para a escolha de um recurso e sua funcionalidade.

Este artigo propõe-se a refletir como as trajetórias pessoal e profissional de Helena Antipoff (1892-1974), aliadas às suas convicções de que a intervenção e transformação do real decorrem do conhecimento acumulado, da experiência e do desejo de ampliar o bem comum são elementos que vão construindo acervos pessoais, a partir dessa triangulação. Esta construção se funda mais nas práticas e ações do que na intenção de elaborar um acervo, mas termina por compor a construção de uma memória, articulada à formação do “Centro de Documentação e Pesquisa Helena Antipoff” – Ibirité-MG. Nascida na Rússia e tendo vivido no Brasil no período de 1929-1974, a educadora destacou-se por ações socialmente relevantes fundadas na organização do estudo e da pesquisa nos campos da psicologia, da educação e da educação rural, sendo estas duas últimas objetos de nossa pesquisa documental e análises.

INTRODUCTION: Studies which verified the effects of physical exercise on oxidative stress biomarkers and its relation to muscle glycogen are lack. OBJECTIVE: The present study verified the effects of aerobic swimming training (AST) on biomarkers of oxidative stress, glycogen content and cell growth in the skeletal muscle of rats. METHODS: Eighteen male Wistar rats (60 days) were divided into two groups: Sedentary Group (SG; n = 10): sedentary rats; and Trained Group (TG; n = 8): rats subjected to AST (5.0% of body weight), 1h/day, 5x/week, during 8 weeks. The activity of antioxidant enzymes (AOE) superoxide dismutase (SOD; U/ml), catalase (CAT; µmol/min/100mg), glutathione peroxidase (GPx; nmol/min/100mg), and substances that react with thiobarbituric acid levels (TBARs; nmolMDA/mg protein) were determined in the right gastrocnemius muscle. Glycogen (mg/100mg), protein (g/100g), and DNA (g/100g) contents were evaluated in the left gastrocnemius muscle. Data were analyzed by Student t-test (p < 0.05). RESULTS: AOE activity was higher in the TG group (CAT: 0.87 ± 0.04; SOD: 6.49 ± 0.45; GPX: 6.49 ± 0.52) when compared to SG group (CAT: 0.52 ± 0.03; SOD: 4.10 ± 0.37; GPx: 2.87 ± 0.35). TBARs levels was lower in TG (TG: 2.35 ± 0.45; SG: 8.90 ± 0.47). Gastrocnemius glycogen content (SG: 0.108 ± 0.013; TG: 0.320 ± 0.012) and protein/DNA ratio (SG: 24.94 ± 3.25; TG: 41.68 ± 4.02) were higher in TG group. CONCLUSION: Altogether, these data provide evidence that AST improved antioxidant defense, which may be associated to higher glycogen content of skeletal muscle of the animals.

This study aimed to investigate the independent and additive effects of counter-resistance training (RT) and soy isoflavone supplement (ISO) on bone mineral density (BMD) and bone turnover in postmenopausal women. This study used a placebo-controlled, double-blinded (soy), randomized two (ISO vs. placebo) x two (RT vs. no RT) design. Eighty sedentary postmenopausal women, aged 45-70 years, were randomly assigned to one of four groups (71 completed a 9-month intervention): RT+ISO (n=15); no RT+ISO (n=20); RT+placebo (n=18); no RT+placebo (n=18). Participants randomized to ISO received 100mg/ day/oral of soy isoflavone; and those to RT attended supervised counter-resistance training sessions at least twice a week. At baseline and 9-month, BMD was estimated by dual-energy X-ray absorptiometry (DXA). Serum levels of C-terminal cross-linked telopeptide of type I collagen (CTX), osteocalcin, and insulin-like growth factor-1 (IGF-1) were measured as bone turnover. ANOVA with time as the repeated measure and test t were used in the statistical analysis. After 9 months of intervention, neither ISO nor RT alone affected BMD at any site or levels of CTX, osteocalcin, and IGF-1 (p>0.05). ISO and RT had no additive effects on BMD and bone turnover. RT groups showed significantly increased muscle strength (+ 35.2%) (p=0.02). We found no additive effects of resistance training and soy isoflavone on bone mineral density or bone turnover in postmenopausal women after 9-months.

INTRODUCTION: Resistance training (RT) has been widely used for older adults in order to minimize or reverse the deleterious effects of aging in the neuromuscular system. However, the potential benefits of RT on arterial blood pressure and heart rate at rest in older adults remain controversial. OBJECTIVE: To analyze the effect of eight weeks of RT on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) in older women without hypertension. METHODS: Seventeen women (aged 66.0 ± 5.8 years) without previous experience in RT were randomly assigned to either a training (TG, n = 10) or control (CG, n = 7) groups. Hemodynamic parameters at rest were evaluated by auscultatory method (mercury sphygmomanometer) and HR monitor (Polar), before and after eight weeks of experimental period. RESULTS: Reductions attributable to RT were found only to SBP (-13.4 mmHg, p <0.01). Although significant reductions were observed for DBP and MBP, the analysis of covariance showed no interaction Group x Time significant. CONCLUSION: RT proved an effective training to promote adaptations in the cardiovascular system of older women without hypertension. Eight weeks of RT can significantly reduce SBP at rest in older women.
