Violence against women in Ethiopia

Investigating the experience of violence against women and exploring women's coping strategies is a crucial component of re-tailoring the provision of services for victims/survivors. This article explores violence against women in the context of culture, theory of fear of violence and literature on spaces perceived to be 'safe' or 'dangerous' by women victims/survivors of violence in Ethiopia. To collect the relevant data, we conducted 14 semi-structured interviews with Ethiopian women who are victims/survivors of violence and three interviews with gender experts in Ethiopia. Our group of women suffer in 'silence' and confide only in friends and relatives. They did not resort to institutional support due to lack of awareness and general societal disapproval of such measures. This contrasts with claims by experts that the needs of these women are addressed using an institutional approach. Culture, migration status and lack of negotiating power in places of work are key factors when considering violence. The majority of the respondents in this study occupy both public and private spaces such as bars and homes and have experienced violence in those spaces. The social relations and subsequent offences they endured do not make spaces such as these safe. Education of both sexes, creation of awareness, sustainable resource allocation to support victims/survivors, ratification of the Maputo protocol and effective law enforcement institutions are some of the practical strategies we propose to mitigate the incidence of violence in Ethiopia. © 2010 Taylor & Francis.

Effect of reading sport chronicles on the perception of justice and the predisposition to protest actions in soccer

In this study three chronicles from national newspapers (one generalist and two sport press) were analyzed. The chronicles belong to Spain’s soccer final of the King’s Cup in 2014. The aim of the study was to know if there was any influence on the readers’ perception of justice and consequently if this influence could cause a particular predisposition to participate in acts of protest. 462 university students participated. The results showed that different chronicles caused differences in the perception of justice depending on the chronicle read. However, a clear influence on the willingness to participate in acts of protest was not obtained. These results should make us think about the impact of sport press and its influence, and to be aware of the indirect responsibility of every sector on the antisocial behaviors generated by soccer in our country.

The Effect of Psychological Distance on Willingness to Engage in Ideologically Based Violence

Research on the cognitive and decision-making processes of individuals who choose to engage in ideologically based violence is vital. Our research examines how abstract and concrete construal mindsets affect likelihood to engage in ideologically based violence. Construal Level Theory (CLT) states that an abstract mindset (high-level construal), as opposed to a concrete mindset (low-level construal), is associated with a greater likelihood of engaging in goal-oriented, value-motivated behaviors. Assuming that ideologically based violence is goal-oriented, we hypothesized that high-level construal should result in an increased likelihood of engaging in ideologically based violence. In the pilot study we developed and tested 24 vignettes covering controversial topics and assessed them on features such as relatability, emotional impact, and capacity to elicit a violent reaction. The ten most impactful vignettes were selected for use in the primary investigations. The two primary investigations examined the effect of high- and low-level construal manipulations on self-reported likelihood of engaging in ideologically based violence. Self-reported willingness was measured through an ideological violence assessment. Data trends implied that participants were engaged in the study, as they reported a higher willingness to engage in ideologically based violence when they had a higher passion for the vignette's social issue topic. Our results did not indicate a significant relationship between construal manipulations and level of passion for a topic.

INJURIES RELATED TO COMPETITIVE AND NONCOMPETITIVE SPORTS IN ELDERLY MEN

Objective: To verify the sociodemographic profile and the frequency of musculoskeletal injuries in elderly people who practice competitive and noncompetitive sports activities in the city of Pelotas, RS. Methods: Descriptive study, including 29 male subjects, aged 65 years or older, who practiced sports modalities in a competitive and noncompetitive way, in the city of Pelotas, in 2015. Data collection was performed through the application of a questionnaire with questions addressing economic, sociodemographic, nutritional and behavioral issues, and injuries sustained in sports activities. Statistical analysis was performed by calculating measures of central tendency for continuous variables and proportions for categorical variables. Results: The current practice of competitive sports was described by 58.6% (n=17) of the subjects, and the most practiced sports were 7-a-side football (53.0%, n=9), tennis (23.5%, n=4) and swimming (23.5%, n=4). Noncompetitive sports were practiced by 44.8% (n=13), and tennis was the most popular sport played (92.3%, n=12). The frequency of injuries among individuals practicing competitive and noncompetitive sports was, respectively, 35.3% (n=6), and 38.5% (n=5). The most frequent injuries were epicondylitis (50.0%, n=3) and meniscus injuries (60.0%, n=3), and the most affected body regions were knee (27.3%, n=3), elbow (27.3%, n=3), and shoulder (18.2%, n=2). The injuries occurred during the sports activities, and the dominant side was the one affected in 63.6% (n=7). Conclusion: This study verified that the occurrence of injuries in elderly individuals who practice sports is relevant, even among those who practice them noncompetitively, with epicondylitis as the most frequent among them, whereas meniscus injuries are the most frequent among those who practice competitive sports.

All Is not English that Glitters: False Anglicisms in the Spanish Language of Sports

Over the past decades, many studies have dealt with Anglicisms in Spanish, not only in science and technology, but also in other areas such as business, fashion and even sports. However, in spite of the large number of works on Spanish Anglicisms in sports, these have often disregarded the distinction between Anglicisms and false Anglicisms. Given their importance as evidence of the particular relationships between languages, this article focuses on the use of false Anglicisms in the Spanish language of sports, which has not only adopted English words giving them new meanings and usage, but has also either imported items with an English appearance from other languages or created its own forms based on English patterns. Although these false Anglicisms, which have proven extremely popular in various European languages (not only Spanish), have frequently been used and disseminated, as some examples will prove, little attention has been paid to their differences with the English term or their non-English origin.

Acute Exercise Decreases Trb3 Protein Levels In The Hypothalamus Of Obese Rats.

To evaluate the effects of acute exercise on the TRB3 protein levels and interaction between TRB3/Akt proteins in the hypothalamus of obese rats. In addition, we evaluated the relationship between TRB3 and endoplasmic reticulum stress (ER stress) and verified whether an acute exercise session is able to influence these processes. In the first part of the study, the rats were divided into three groups: control (lean) - fed with a standard rodent chow, DIO - fed with a high fat diet and DIO submitted to a swimming acute exercise protocol (DIO-EXE). In the second part of the study, we used other three groups: control (lean) receiving an intracerebroventricular (i.c.v.) infusion of vehicle, lean receiving an i.c.v. infusion of thapsigargin, and lean receiving an i.c.v infusion of thapsigargin and performing an acute exercise session. Four hours after the exercise session, the food intake was measured and the hypothalamus was dissected and separated for subsequent protein analysis by immunoblotting and Real Time PCR. The acute exercise session reduced the TRB3 protein levels, disrupted the interaction between TRB3/Akt proteins, increased the phosphorylation of Foxo1 and restored the anorexigenic effects of insulin in the hypothalamus of DIO rats. Interestingly, the suppressive effects of acute exercise on TRB3 protein levels may be related, at least in part, to the decrease of ER stress (evaluated though pancreatic ER kinase phosphorylation - pPERK and C/EBP homologous protein - CHOP protein levels) in the hypothalamus. In conclusion, the reduction of hypothalamic TRB3 protein levels mediated by exercise may be associated with the reduction of ER stress. These data provided a new mechanism by which an acute exercise session improves insulin sensitivity in hypothalamus and restores food intake control in obesity.

Resistance Training with Vascular Occlusion in Inclusion Body Myositis: A Case Study

GUALANO, B., M. NEVES JR, F. R. LIMA, A. L. PINTO, G. LAURENTINO, C. BORGES, L. BAPTISTA, G. G. ARTIOLI, M. S. AOKI, A. MORISCOT, A. H. LANCHA JR, E. BONFA, and C. UGRINOWITSCH. Resistance Training with Vascular Occlusion in Inclusion Body Myositis: A Case Study. Med Sci. Spot-is Exerc., Vol. 42, No. 2, pp. 250-254, 2010. Inclusion body myositis (IBM) is a rare idiopathic inflammatory myopathy that produces remarkable muscle weakness. Resistance training with vascular occlusion has been shown to improve muscle strength and cross-sectional area in other muscle wasting conditions. Purpose: We evaluated the efficacy of a moderate-intensity resistance training program combined with vascular occlusion by examining functional capacity, muscle morphology, and changes in the expression of genes related to muscle protein synthesis and proteolysis in a patient with IBM. Methods: A 65-yr-old man with IBM resistant to all proposed treatments underwent resistance training with vascular occlusion for 12 wk. Leg press one-repetition maximum; thigh cross-sectional area; balance, mobility, and muscle function; quality of life; and blood markers of inflammation and muscle damage were assessed at baseline and after the 12-wk program. The messenger RNA (mRNA) expression levels of mechanogrowth factor, mammalian target of rapamycin, atrogin-1, and muscle RING finger-1 were also quantified. Results: After the 12-wk training program, the patient`s leg press one-repetition maximum, balance and mobility function, and thigh cross-sectional area increased 15.9%, 60%, and 4.7%, respectively. All Short Form-36 Health Survey Questionnaire subscales demonstrated improvements as well, varying from 18% to 600%. mRNA expression of mechanogrowth factor increased 3.97-fold, whereas that of atrogin-1 decreased 0.62-fold. Muscle RING finger-1 and mammalian target of rapamycin mRNA levels were only slightly altered, 1.18- and 1.28-fold, respectively. Importantly, the exercise did not induce disease flare. Conclusions: We describe a novel, and likely the first, nonpharmacological therapeutic tool that might be able to counteract the muscle atrophy and the declining strength that usually occur in IBM.

Exercise Intensity, Inflammatory Signaling, and Insulin Resistance in Obese Rats

DA SILVA, A. S. R., J. R. PAULI, E. R. ROPELLE, A. G. OLIVEIRA, D. E. CINTRA, C. T. DE SOUZA, L. A. VELLOSO, J. B. C. CARVALHEIRA, and M. J. A. SAAD. Exercise Intensity, Inflammatory Signaling, and Insulin Resistance in Obese Rats. Med. Sci. Sports Exerc., Vol. 42, No. 12, pp. 2180-2188, 2010. Purpose: To evaluate the effects of intensity of exercise on insulin resistance and the expression of inflammatory proteins in the skeletal muscle of diet-induced obese (DIO) rats after a single bout of exercise. Methods: In the first exercise protocol, the rats swam for two 3-h bouts, separated by a 45-min rest period (with 6 h in duration-DIO + EXE), and in the second protocol, the rats were exercised with 45 min of swimming at 70% of the maximal lactate steady state-MLSS (DIO + MLSS). Results: Our data demonstrated that both protocols of exercise increased insulin sensitivity and increased insulin-stimulated tyrosine phosphorylation of insulin receptor and insulin receptor substrate 1 and serine phosphorylation of protein kinase B in the muscle of DIO rats by the same magnitude. In parallel, both exercise protocols also reduced protein tyrosine phosphatase 1B activity and insulin receptor substrate 1 serine phosphorylation, with concomitant reduction in c-jun N-terminal kinase and I kappa B kinase activities in the muscle of DIO rats in a similar fashion. Conclusions: Thus, our data demonstrate that either exercise protocols with low intensity and high volume or exercise with moderate intensity and low volume represents different strategies to restore insulin sensitivity with the same efficacy.

Abnormal Neurovascular Control in Anabolic Androgenic Steroids Users

NUNES ALVES, M. J. N., M. R. DOS SANTOS, R. G. DIAS, C. A. AKIHO, M. C. LATERZA, M. U. P. B. RONDON, R. L. DE MORAES MOREAU, and C. E. NEGRAO. Abnormal Neurovascular Control in Anabolic Androgenic Steroids Users. Med. Sci. Sports Exerc., Vol. 42, No. 5, pp. 865-871, 2010. Purpose: Previous studies showed that anabolic androgenic steroids (AAS) increase vascular resistance and blood pressure (BP) in humans. In this study, we tested the hypotheses 1) that AAS users would have increased muscle sympathetic nerve activity (MSNA) and reduced forearm blood flow (FBF) compared with AAS nonusers and 2) that there would be an association between MSNA and 24-h BP. Methods: Twelve AAS users aged 31 +/- 2 yr (means +/- SE) and nine age-matched AAS nonusers aged 29 T 2 yr participated in the study. All individuals were involved in strength training for at least 2 yr. AAS was determined by urine test (chromatography-mass spectrometry). MSNA was directly measured by microneurography technique. FBF was measured by venous occlusion plethysmography. BP monitoring consisted of measures of BP for 24 h. Results: MSNA was significantly higher in AAS users than that in AAS nonusers (29 +/- 3 vs 20 +/- 1 bursts per minute, P = 0.01). FBF (1.92 +/- 0.17 vs 2.77 +/- 0.24 mL.min(-1).100 mL(-1), P = 0.01) and forearm vascular conductance (2.01 +/- 0.17 vs 2.86 +/- 0.31 U, P = 0.02) were significantly lower in AAS users than that in AAS nonusers. Systolic (131 +/- 4 vs 120 +/- 3 mm Hg, P = 0.001), diastolic (74 +/- 4 vs 68 +/- 3 mm Hg, P = 0.02), and mean BP (93 +/- 4 vs 86 +/- 3 mm Hg, P = 0.005) and heart rate (74 +/- 3 vs 68 +/- 3 bpm, P = 0.02) were significantly higher in AAS users when compared with AAS nonusers. Further analysis showed that there was a significant correlation between MSNA and 24-h mean BP (r = 0.75, P = 0.002). Conclusions: AAS increases MSNA and reduces muscle blood flow in young individuals. In addition, the increase in BP levels in AAS users is associated with augmented sympathetic outflow. These findings suggest that AAS increases the susceptibility for cardiovascular disease in humans.

Creatine in Type 2 Diabetes: A Randomized, Double-Blind, Placebo-Controlled Trial

GUALANO, B., V. DE. SALLES PAINNELI, H. ROSCHEL, G. G. ARTIOLI, M. NEVES JR, A. L. DE SA PINTO, M. E. DA SILVA, M. R. CUNHA, M. C. G. OTADUY, C. DA COSTA LEITE, J. C. FERREIRA, R. M. PEREIRA, P. C. BRUM, E. BONFA, and A. H. LANCHA JR. Creatine in Type 2 Diabetes: A Randomized, Double-Blind, Placebo-Controlled Trial. Med. Sci. Sports Exerc., Vol. 43, No. 5, pp. 770-778, 2011. Creatine supplementation improves glucose tolerance in healthy subjects. Purposes: The aim was to investigate whether creatine supplementation has a beneficial effect on glycemic control of type 2 diabetic patients undergoing exercise training. Methods: A 12-wk randomized, double-blind, placebo-controlled trial was performed. The patients were allocated to receive either creatine (CR) (5 g.d(-1)) or placebo (PL) and were enrolled in an exercise training program. The primary outcome was glycosylated hemoglobin (Hb(A1c)). Secondary outcomes included the area under the curve of glucose, insulin, and C-peptide and insulin sensitivity indexes. Physical capacity, lipid profile, and GLUT-4 protein expression and translocation were also assessed. Results: Twenty-five subjects were analyzed (CR: n = 13; PL: n = 12). Hb(A1c) was significantly reduced in the creatine group when compared with the placebo group (CR: PRE = 7.4 +/- 0.7, POST = 6.4 +/- 0.4; PL: PRE = 7.5 +/- 0.6, POST = 7.6 +/- 0.7; P = 0.004; difference = -1.1%, 95% confidence interval = -1.9% to -0.4%). The delta area under the curve of glucose concentration was significantly lower in the CR group than in the PL group (CR = -7790 +/- 4600, PL = 2008 +/- 7614; P = 0.05). The CR group also presented decreased glycemia at times 0, 30, and 60 min during a meal tolerance test and increased GLUT-4 translocation. Insulin and C-peptide concentrations, surrogates of insulin sensitivity, physical capacity, lipid profile, and adverse effects were comparable between the groups. Conclusions: Creatine supplementation combined with an exercise program improves glycemic control in type 2 diabetic patients. The underlying mechanism seems to be related to an increase in GLUT-4 recruitment to the sarcolemma.

Beneficial Effect of Creatine Supplementation in Knee Osteoarthritis

NEVES JR., M., B. GUALANO, H. ROSCHEL, R. FULLER, F. B. BENATTI, A. L. DE SA PINTO, F. R. LIMA, R. M. PEREIRA, A. H. LANCHA JR., E. BONFA. Beneficial Effect of Creatine Supplementation in Knee Osteoarthritis. Med. Sci. Sports Exerc., Vol. 43, No. 8, pp. 1538-1543, 2011. Introduction: The aim of this study was to investigate the efficacy of creatine (CR) supplementation combined with strengthening exercises in knee osteoarthritis (OA). Methods: A randomized, double-blind, placebo-controlled trial was performed. Postmenopausal women with knee OA were allocated to receive either CR (20 g.d(-1) for 1 wk and 5 g.d(-1) thereafter) or placebo (PL) and were enrolled in a lower limb resistance training program. They were assessed at baseline (PRE) and after 12 wk (POST). The primary outcome was the physical function as measured by the timed-stands test. Secondary outcomes included lean mass, quality of life, pain, stiffness, and muscle strength. Results: Physical function was significantly improved only in the CR group (P = 0.006). In addition, a significant between-group difference was observed (CR: PRE = 15.7 +/- 1.4, POST = 18.1 +/- 1.8; PL: PRE = 15.0 +/- 1.8, POST = 15.2 +/- 1.2; P = 0.004). The CR group also presented improvements in physical function and stiffness subscales as evaluated by the Western Ontario and McMaster Universities Osteoarthritis Index (P = 0.005 and P = 0.024, respectively), whereas the PL group did not show any significant changes in these parameters (P > 0.05). In addition, only the CR group presented a significant improvement in lower limb lean mass (P = 0.04) as well as in quality of life (P = 0.01). Both CR and PL groups demonstrated significant reductions in pain (P G 0.05). Similarly, a main effect for time revealed an increase in leg-press one-repetition maximum (P = 0.005) with no significant differences between groups (P = 0.81). Conclusions: CR supplementation improves physical function, lower limb lean mass, and quality of life in postmenopausal women with knee OA undergoing strengthening exercises.

Effects of Aerobic Training on Airway Inflammation in Asthmatic Patients

MENDES, F. A. R., F. M. ALMEIDA, A. CUKIER, R. STELMACH, W. JACOB-FILHO, M. A. MARTINS, and C. R. F. CARVALHO. Effects of Aerobic Training on Airway Inflammation in Asthmatic Patients. Med. Sci. Sports Exerc., Vol. 43, No. 2, pp. 197-203, 2011. Purpose: There is evidence suggesting that physical activity has anti-inflammatory effects in many chronic diseases; however, the role of exercise in airway inflammation in asthma is poorly understood. We aimed to evaluate the effects of an aerobic training program on eosinophil inflammation (primary aim) and nitric oxide (secondary aim) in patients with moderate or severe persistent asthma. Methods: Sixty-eight patients randomly assigned to either control (CG) or aerobic training (TG) groups were studied during the period between medical consultations. Patients in the CG (educational program + breathing exercises; N = 34) and TG (educational program + breathing exercises + aerobic training; N = 34) were examined twice a week during a 3-month period. Before and after the intervention, patients underwent induced sputum, fractional exhaled nitric oxide (FeNO), pulmonary function, and cardiopulmonary exercise testing. Asthma symptom-free days were quantified monthly, and asthma exacerbation was monitored during 3 months of intervention. Results: At 3 months, decreases in the total and eosinophil cell counts in induced sputum (P = 0.004) and in the levels of FeNO (P = 0.009) were observed after intervention only in the TG. The number of asthma symptom-free days and (V) over dotO(2max) also significantly improved (P < 0.001), and lower asthma exacerbation occurred in the TG (P < 0.01). In addition, the TG presented a strong positive relationship between baseline FeNO and eosinophil counts as well as their improvement after training (r = 0.77 and r = 0.9, respectively). Conclusions: Aerobic training reduces sputum eosinophil and FeNO in patients with moderate or severe asthma, and these benefits were more significant in subjects with higher levels of inflammation. These results suggest that aerobic training might be useful as an adjuvant therapy in asthmatic patients under optimized medical treatment.

Out of the shadows: The critical sociology of sport in Australia, 1986 to 1996

The sociology of sport in Australia has reached a key point in its development. A critical tradition in the subdiscipline has been established over the last decade, but its intellectual and institutional progress has been uneven. This article briefly traces the emergence of critical sports sociology in a country outside the major centers in the UK and U.S., its break with functionalist approaches, and its attempts to overcome the neglect of local mainstream sociology. The authors proceed to examine (self-reflexively) the changes of theoretical direction and the new lines of research that are being explored in the field. A recent ''skirmish'' with narrative history over the preferred theories and methods in sports analysis is discussed as illustrative of the difficulties encountered by an energetic but small, dispersed and underorganized scholarly movement in Australia.
