RESUMoExistem evidências de que exercícios resistidos contribuem para o controle de hipertensão arterial sistêmica, porém, são necessários estudos que indiquem a melhor forma de utilizá-los. O objetivo deste estudo foi analisar a influência da ordem de execução de exercícios resistidos na hipotensão pós-exercício em idosos com hipertensão arterial bem controlada. A amostra foi composta por oito idosos com hipertensão arterial sistêmica bem controlada (quatro homens e quatro mulheres). No protocolo 1 (P1) foram realizados inicialmente três exercícios para membros superiores e, posteriormente, três exercícios para membros inferiores. No protocolo 2 (P2) a sequência foi inversa. Já no protocolo 3 (P3) os exercí-cios foram realizados de forma alternada. Todos os exercícios foram realizados em três séries de 12 RM. Após cada protocolo a pressão arterial (PA) foi verificada em intervalos de 10 minutos, até 60 minutos pós-exercício. Os dados obtidos foram analisados através da ANOVA de fator duplo e fator único com post-hoc de Tukey e teste t de Student pareado com distribuição bicaudal (p < 0,05). Em relação ao repouso, as seis verificações de PA pós-exercício de P1 não apresentaram diferenças significativas; no P2 foram significantemente diferentes apenas as verificações de 20 e 40 minutos na PAS; no P3 foram observadas diferenças significativas em todas as seis verificações da PAS e nas de 10, 20, 30 e 60 minutos da PAD. A verificação de 20 minutos na PAD do P3 demonstrou-se significantemente diferente das de 20 minutos de P1 e P2. Conclui-se que a ordem de realização de exercícios resistidos em idosos com hipertensão arterial bem controlada influenciou na duração da resposta hipotensiva, mas não diretamente em sua magnitude.Palavras-chave: pressão arterial, massa muscular, tratamento não farmacológico. aBStRaCtThere is evidence that resistance training can help to control hypertension, although further studies are needed to show the best way to perform it. The objective of this study was to analyze the influence of the resistance exercises order performance in post-exercise hypotension in elderly with controlled hypertension. The study sample consisted of eight elderly with controlled hypertension (four men and four women). In exercise protocol 1 (P1), they performed three upper limb exercises and then three lower limb exercises. In exercise protocol 2 (P2) the sequence was reversed. In exercise protocol 3 (P3) the subjects performed the same exercises in an alternate way. All exercises were performed in three sets of 12RM. Blood pressure (BP) was measured after each protocol at every 10 min until 60 min post-exercise. The data obtained were assessed using two-way ANOVA with post-hoc Tukey and paired Student's t test (p<0.05). Concerning rest values, P1 did not show statistically significance in any moment; however, in P2 at 20 and 40 min Systolic Blood Pressure (SBP) values were statistically significant. Moreover, P3 showed differences in all SBP moments and also in the 10, 20, 30 and 60 min of Diastolic Blood Pr...

OBJECTIVE:Oxidative stress plays an important role in skeletal muscle damage in sepsis. Aerobic exercise can decrease oxidative stress and enhance antioxidant defenses. Therefore, it was hypothesized that aerobic exercise training before a sepsis stimulus could attenuate skeletal muscle damage by modulating oxidative stress. Thus, the aim of this study was to evaluate the effects of aerobic physical preconditioning on the different mechanisms that are involved in sepsis-induced myopathy.METHODS:Male Wistar rats were randomly assigned to either the untrained or trained group. The exercise training protocol consisted of an eight-week treadmill program. After the training protocol, the animals from both groups were randomly assigned to either a sham group or a cecal ligation and perforation surgery group. Thus, the groups were as follows: sham, cecal ligation and perforation, sham trained, and cecal ligation and perforation trained. Five days after surgery, the animals were euthanized and their soleus and plantaris muscles were harvested. Fiber cross-sectional area, creatine kinase, thiobarbituric acid reactive species, carbonyl, catalase and superoxide dismutase activities were measured.RESULTS:The fiber cross-sectional area was smaller, and the creatine kinase, thiobarbituric acid reactive species and carbonyl levels were higher in both muscles in the cecal ligation and perforation group than in the sham and cecal ligation and perforation trained groups. The muscle superoxide dismutase activity was higher in the cecal ligation and perforation trained group than in the sham and cecal ligation and perforation groups. The muscle catalase activity was lower in the cecal ligation and perforation group than in the sham group.CONCLUSION:In summary, aerobic physical preconditioning prevents atrophy, lipid peroxidation and protein oxidation and improves superoxide dismutase activity in the skeletal muscles of septic rats.

This study explores the relationship between organisational culture and total quality management (TQM) implementation in Australia, with the purpose of identifying the particular culture that dominants the Australian construction industry, and distinguishing which cultures determine the successful implementation of TQM. Although the application of the competing values framework (CVF) for evaluating organisational culture (OC) in the construction industry has been studied by some scholars, research into OC and its impact on TQM procedures in connection to the CVF in project-based industries such as construction has received less attention. Thus, this research intends to determine the relationship between OC and TQM regarding the CVF in the Australian construction industry. The research methodology used the validated organisational culture assessment instrument (OCAI) CVF to frame OC, and TQM practices identified from the literature review. An online questionnaire was distributed through Qualtrics, whereby 42 valid responses representing various construction organisations in Australia were analysed through IBM SPSS Statistics 26 through endorsing k-means cluster analysis, and analysis of variance. The findings support that Australian construction organisations are dominated by the market and external focused cultures according to the CVF of organisational classification. Furthermore, the findings acknowledge that organisations that are dominated by hierarchical cultural characterises could provide an unfavourable environment for the successful implementation of TQM. Whilst an organisation that obtains a mix of cultures, specifically with the adhocracy and market cultures dominating could provide a favourable environment for the successful implementation of TQM.
