Treinamento aeróbio de natação aumenta a atividade de enzimas antioxidantes e o conteúdo de glicogênio no musculoesquelético de ratos

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.

Efeito do treinamento contrarresistência e isoflavona na densidade mineral óssea em mulheres na pós-menopausa

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.

Efeito do treinamento com pesos na pressão arterial de repouso em idosas normotensas

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.

Formação para o ensino agrícola nos Centros de Treinamento de Professores e de Auxiliares Rurais (1952-1963)

This paper analyzes agricultural education as proposed and developed by the National Campaign for Rural Education (1952-1963) in Training Centers for Rural Teachers and Assistants. It analyzes the curricula of such courses published by the campaign in special issue, number 10 in 1961/1962. Agricultural education was a part of rural education and aimed to train rural teachers and expand the knowledge of rural men to make them remain in their environment. This training aimed to address the shortage of rural teachers, of agricultural knowledge, rural hygiene, strongly guided by the education of manners, of how to behave at the table and by the appreciation of rational leisure, together with campaigns for civil and marriage registration, a campaign for trees, encouragement to elect representatives to boards as a means of educating for citizenship. Such lack of rural teachers and the complaints about low wages disclose the practices of our current rulers who devalue the teaching profession.

Análise morfológica do músculo gastrocnêmio medial de ratos submetidos a um protocolo de treinamento concorrente

The aim of this study was to analyze the morphophysiological changes of medial gastrocnemius muscle (GM) of Wistar rats underwent to eight weeks of concurrent training (TC). We used fifteen male Wistar rats divided into three groups with five animals each: baseline (LB), control (C) and trained (T). The TC consisted of aerobic endurance training in swimming (TRA) and a forced training (TF) in the same session, three times per week, for eight weeks. There was an increase of 4.4% in the comparison between average cross section area of the GM in animals of groups T (4905,5 ± 77,1µm²) and C (4699,9 ± 78,3 µm²). It is concluded that concurrent training was effective in causing hypertrophy in GM of rats.
