Osório, Helena B. Rower, Marina R. Barbosa, Joao Gabriel S.T. da Silva, Bernardete Weber, Alexandre B. Cavalcanti, Aline Marcadenti Journal of Hypertension, 2024 Objective: To evaluate the effectiveness of a nutritional strategy based on two components and adapted for the public health system on blood pressure, cardiometabolic features, self-care, qualify of life and diet quality in individuals with hypertension. Methods: NUPRESS was an open-label, parallel-group, superiority randomized controlled clinical trial in which participants at least 21 years with hypertension and poorly controlled blood pressure were randomly assigned (1 : 1 allocation ratio) to either an individualized dietary prescription according to nutritional guidelines (control group, n = 205); or a two-component nutrition strategy, including a goal-directed nutritional counseling and mindfulness techniques (NUPRESS [intervention] group, n = 205). Primary outcomes were SBP (mmHg) after 24 weeks of follow up and blood pressure control, defined as either having SBP more than 140 mmHg at baseline and achieving 140 mmHg or less after follow-up or having SBP 140 mmHg or less at baseline and reducing the frequency of antihypertensive drugs in use after follow-up. Results: In total, 410 participants were randomized and submitted to an intention-to-treat analysis regarding primary outcomes. Both groups decreased blood pressure, but after adjusting for baseline values, there was no significant difference between them on SBP [intervention-control difference: -0.03 (-3.01; 2.94); P = 0.98] nor blood pressure control [odds ratio 1.27 (0.82; 1.97); P = 0.28]. No differences between groups were also detected regarding secondary and tertiary outcomes. Conclusion: There was no difference between a two-component nutritional strategy and an established dietary intervention on blood pressure in participants with hypertension.
Resistance training prevents dynamics and mitochondrial respiratory dysfunction in vastus lateralis muscle of ovariectomized rats Cecília Tardivo Marin, Anderson Diogo de Souza Lino, Iara Dinik Santos Avelar, Marina Rodrigues Barbosa, Gabriel Carlos Goulart Scarlato, Diego Felipe Cavalini, Fábio Tamanini, André Vessoni Alexandrino, Anibal Eugênio Vercesi, Gilberto Eiji Shiguemoto Experimental Gerontology, 2023 To investigate whether ovariectomy affects mitochondrial respiratory function, gene expression of the biogenesis markers and mitochondrial dynamics of the vastus lateralis muscle, female Wistar rats divided into ovariectomized (OVX) and intact (INT) groups were kept sedentary (SED) or submitted to resistance training (RT) performed for thirteen weeks on a vertical ladder in which animals climbed with a workload apparatus. RT sessions were performed with four climbs with 65, 85, 95, and 100 % of the rat's previous maximum workload. Mitochondrial Respiratory Function data were obtained by High-resolution respirometry. Gene expression of FIS1, MFN1 and PGC1-α was evaluated by real-time PCR. There was a decrease on oxidative phosphorylation capacity in OVX-SED compared to other groups. Trained groups presented increase on oxidative phosphorylation capacity when compared to sedentary groups. For respiratory control ratio (RCR), OVX-SED presented lower values when compared to INT-SED and to trained groups. Trained groups presented RCR values higher compared to INT-SED. Exercise increased the values of FIS1, MFN1 and PGC1-α expression compared to OVX-SED. Our results demonstrated that in the absence of ovarian hormones, there is a great decrease in oxidative phosphorylation and electron transfer system capacities of sedentary animals. RT was able to increase the expression of genes related to mitochondrial dynamics markers, reversing the condition determined by ovariectomy.
Circuit resistance training in women with normal weight obesity syndrome: Body composition, cardiometabolic and echocardiographic parameters, and cardiovascular and skeletal muscle fitness Fabiano C. Ferreira, Danilo R. Bertucci, Marina R. Barbosa, João E. Nunes, João P. Botero, Maria F. Rodrigues, Gilberto E. Shiguemoto, Valdir Santoro, Ana C. Verzola, Rodrigo O. Nonaka, Roberto M. Verzola, Vilmar Baldissera, Sérgio E. Perez Journal of Sports Medicine and Physical Fitness, 2017 BACKGROUND: Normal weight obesity (NWO) syndrome has been characterized in subjects with normal Body Mass Index (BMI) and high body fat mass percentage (BF%>30 for women) being a risk factor for cardiometabolic dysregulation and cardiovascular mortality. This study evaluated whether circuit resistance training (CRT) improves body composition, heart size and function, cardiometabolic parameters, and cardiorespiratory, cardiovascular and skeletal muscle fitness in women with NWO. METHODS: Data are means (95% Confidence Interval). Twenty-three women participated: 10 NWO-CRT (baseline: BMI=22.4 [21.4-23.3] kg/m2; BF%=44.5 [41.0-48.0]%) performed CRT; and 13 untrained NWO-control (baseline: BMI=21.7 [20.8-22.7] kg/m2; BF%=37.8 [34.6-41.1]%). At baseline and after 10 weeks were performed/measured dual-energy X-ray absorptiometry, echocardiography, blood tests, arterial pressure, exercise testing, and total-overload-by-training-session (TOL). RESULTS: At baseline, the NWO-CRT exhibited larger BF (27.28 [23.9-30.6] kg) than NWO-control (22.41 [19.5-25.3] kg) (P=0.0227). After training, NWO-CRT: reduced 8 kg of BF (P=0.000002); became BF% lower than NWO-control (33.1 [30.1-36.0] <37.0 [34.3-39.6]%, P=0.0423), with 30% of NWO-CRT subjects becoming without-obesity; reduced 3 kg in trunk fat mass (P=0.000005); showed fasting glucose (72.8 [69.4-76.2] mg/dL) smaller than NWO-control (81.7 [78.6-84.8] mg/dL) (P=0.004); increased TOL (5087.5 [4142.5-6032.5] to 6963.3 [6226.4-7700.2] rep.kg, P=0.0004); increased load at VO2peak (122.5 [106.8-138.2] to 137.5 [118.18-156.82] W, P=0.0051); reduced double product/load at VO2peak ratio (277.4 [222.1-332.8] to 237.7 [194.2-281.2] mmHg.bpm/W, P=0.0015); and increased left ventricular mass/body surface area ratio (84.29 [78.98-89.6] to 90.29 [81.45-99.12] g/m2, P=0.0215). CONCLUSIONS: CRT reduced BF% and generated cardiometabolic, cardiac, skeletal muscle and cardiovascular benefits, being a useful strategy to combat the normal weight obesity syndrome in women.
Effects of resistance training and estrogen replacement on adipose tissue inflammation in ovariectomized rats Maria Fernanda Cury Rodrigues, Fabiano Candido Ferreira, Natália Santanielo Silva-Magosso, Marina Rodrigues Barbosa, Markus Vinicius Campos Souza, Mateus Moraes Domingos, Gustavo Henrique Rigo Canevazzi, Uliana Sbeguen Stotzer, Sabrina Messa Peviani, Fábio Santos de Lira, Heloísa Sobreiro Selistre de Araújo, Sérgio Eduardo de Andrade Perez Applied Physiology Nutrition and Metabolism, 2017 Estrogen deficiency is directly related to central obesity and low-grade inflammation. Hormonal replacement and exercise training are both able to decrease fat accumulation and inflammation in postmenopausal women. However, the efficiency of resistance training (RT) and estrogen replacement (ER) in minimizing adiposity and inflammation in the visceral adipose tissue (VAT) of ovariectomized (OVX) rats has not yet been elucidated. In this study, Sprague–Dawley rats were divided into the following 6 groups: sham-operated sedentary (Sham-Sed), OVX-Sed, Sham-RT, OVX-RT, OVX-Sed-ER, and OVX-RT-ER groups. ER was performed by implanting silastic capsules containing 17β-estradiol. For RT, the animals were required to climb a 1.1-m vertical ladder with conical flasks containing weights attached to their tails for 12 weeks. Histological analyses were used to evaluate morphological changes. Gene expression levels were determined by quantitative real-time reverse transcriptase polymerase chain reaction, and protein concentrations were determined using Multiplex/Luminex assays. Ovariectomy increased the body mass (BM), adipocyte area, and inflammation in the VAT, the latter of which was indicated by reduced interleukin-10 (48%) and increased tumor necrosis factor (TNF)-α concentration (∼3%). RT efficiently decreased BM, adipocyte area, and inflammation in the OVX groups. The combination of RT and ER decreased BM (19%) and the TNF-α concentration (18%) and increased the gene and protein expression levels of adiponectin (173% and 18%). These results indicate that RT and the combination of RT and ER are efficient strategies for reducing the BM and improving the inflammatory status of OVX rats.
Resistance training and hormone replacement increase MMP-2 activity, quality and quantity of bone in ovariectomized rats Markus V.C Souza, Anderson D. S Lino, Leandro G. D Ruffoni, Mateus M. Domingos, Marina R. Barbosa, Maria F C. Rodrigues, Fabiano C. Ferreira, Luciane M. Tomaz, Gustavo H. R. Canevazzi, Natália S. Silva, Jeferson A. A. Teixeira, Richard D. Leite, Gilberto E. Shiguemoto, Sérgio E. A. Perez Motriz Revista De Educacao Fisica, 2017 AIMS The aim of the present study was to investigate the influence of resistance training (RT) and hormone replacement (HR) on MMP-2 activity, biomechanical and physical properties bone of ovariectomized (OVX) rats. METHODS Sprague-Dawley female rats were grouped into six experimental groups (n = 11 per group): sham-operated sedentary (SHAM Sed), ovariectomized sedentary (OVX Sed), sham-operated resistance training (SHAM RT), ovariectomized resistance training (OVX RT), ovariectomized sedentary hormone replacement (OVX Sed-HR), and ovariectomized resistance training hormone replacement (OVX RT-HR). HR groups received implanted silastic capsules with a 5% solution of 17β-estradiol (50 mg 17β-estradiol/ml of sunflower oil). In a 12-week RT period (27 sessions; 4-9 climbs) the animals climbed a 1.1 m vertical ladder with weights attached to their tails. Biomechanical and physical bone analyses were performed using a universal testing machine, and MMP-2 activity analysis was done by zymography. RESULTS Bone density and bone mineral content was higher in the RT and HR groups. The MMP-2 activity was higher in the RT and HR groups. The biomechanical analysis (stiffness, fracture load and maximum load) demonstrated better bone tissue quality in the RT associated with HR. CONCLUSION The RT alone as well as when it is associated with HR was efficient in increasing MMP-2 activity, biomechanical and biophysical properties bone of ovariectomized rats.
Resistance Training and Ovariectomy: Antagonic Effects in Mitochondrial Biogenesis Markers in Rat Skeletal Muscle M. Barbosa, G. Shiguemoto, L. Tomaz, F. Ferreira, M. Rodrigues, M. Domingues, M. Souza Master, G. Canevazzi, N. Silva-Magosso, H. Selistre-de-Araujo, S. Perez International Journal of Sports Medicine, 2016 Estrogen reduction is associated with a decline in skeletal muscle mitochondrial biogenesis. Molecular events associated with improvements in markers of mitochondrial biogenesis after resistance training and estradiol replacement are unknown. This study aimed to investigate the effects of ovariectomy, resistance training, and estradiol replacement on markers of mitochondrial biogenesis and protein expression related to oxidative capacity in the rat gastrocnemius pool. Estradiol replacement was performed using Silastic(®) capsules. During the 12-week resistance training, animals climbed a ladder with weights attached to their tails. Gene expression was analysed by RT-PCR, and protein content was determined by western blotting. Ovariectomy decreased the gene expression of the mitochondrial biogenesis markers PGC-1α (~73%), NRF-1 (~44%), and TFAM (~53%) (p<0.05) and decreased the protein expression of phosphorylated AMPK, CREB and AKT, which are related to oxidative capacity. Resistance training increased PGC-1α (~59%) and TFAM (~48%) expression compared to the Ovariectomy-Sedentary group. The combination of resistance training and estradiol replacement was superior to the ovariectomy-sedentary and ovariectomy-resistance training treatments regarding the gastrocnemius muscle. Estrogen deficiency altered the expression of genes and proteins that favour the development of a mitochondrial dysfunction phenotype, which was improved with resistance training and was partially improved by estradiol replacement.
