- Liposuction Induces a Compensatory Increase of Visceral Fat Which Is Effectively Counteracted by Physical Activity: A Randomized Trial(2012) BENATTI, Fabiana; SOLIS, Marina; ARTIOLI, Guilherme; MONTAG, Eduardo; PAINELLI, Vitor; SAITO, Fabio; BAPTISTA, Luciana; COSTA, Luiz Augusto; NEVES, Rodrigo; SEELAENDER, Marilia; FERRIOLLI, Eduardo; PFRIMER, Karina; LIMA, Fernanda; ROSCHEL, Hamilton; GUALANO, Bruno; LANCHA JR., AntonioContext: Liposuction is suggested to result in long-term body fat regain that could lead to increased cardiometabolic risk. We hypothesized that physical activity could prevent this effect. Objective: Our objective was to investigate the effects of liposuction on body fat distribution and cardiometabolic risk factors in women who were either exercise trained or not after surgery. Design, Setting, and Participants: Thirty-six healthy normal-weight women participated in this 6-month randomized controlled trial at the University of Sao Paulo, Sao Paulo, Brazil. Interventions: Patients underwent a small-volume abdominal liposuction. Two months after surgery, the subjects were randomly allocated into two groups: trained (TR, n = 18, 4-month exercise program) and nontrained (NT, n = 18). Main Outcome Measures: Body fat distribution (assessed by computed tomography) was assessed before the intervention (PRE) and 2 months (POST2), and 6 months (POST6) after surgery. Secondary outcome measures included body composition, metabolic parameters and dietary intake, assessed at PRE, POST2, and POST6, and total energy expenditure, physical capacity, and sc adipocyte size and lipid metabolism-related gene expression, assessed at PRE and POST6. Results: Liposuction was effective in reducing sc abdominal fat (PRE vs. POST2, P = 0.0001). Despite the sustained sc abdominal fat decrement at POST6 (P = 0.0001), the NT group showed a significant 10% increase in visceral fat from PRE to POST6 (P = 0.04; effect size = -0.72) and decreased energy expenditure (P = 0.01; effect size = 0.95) when compared with TR. Dietary intake, adipocyte size, and gene expression were unchanged over time. Conclusion: Abdominal liposuction does not induce regrowth of fat, but it does trigger a compensatory increase of visceral fat, which is effectively counteracted by physical activity.
- Safety and possible effects of low-intensity resistance training associated with partial blood flow restriction in polymyositis and dermatomyositis(2014) MATTAR, Melina Andrade; GUALANO, Bruno; PERANDINI, Luiz Augusto; SHINJO, Samuel Katsuyuki; LIMA, Fernanda Rodrigues; SA-PINTO, Ana Lucia; ROSCHEL, HamiltonIntroduction: Our aim was to evaluate the safety and efficacy of a low-intensity resistance training program combined with partial blow flow restriction (BFR training) in a cohort of patients with polymyositis (PM) and dermatomyositis (DM). Methods: In total, 13 patients with PM and DM completed a 12-week twice a week low-intensity (that is, 30% one-repetition-maximum (1RM)) resistance exercise training program combined with partial blood flow restriction (BFR). Assessments of muscle strength, physical function, quadriceps cross sectional (CSA) area, health-related quality of life, and clinical and laboratory parameters were assessed at baseline and after the intervention. Results: The BFR training program was effective in increasing the maximal dynamic strength in both the leg-press (19.6%, P < 0.001) and knee-extension exercises (25.2% P < 0.001), as well as in the timed-stands (15.1%, P < 0.001) and timed-up-and-go test (-4.5%, P = 0.002). Quadriceps CSA was also significantly increased after the intervention (4.57%, P = 0.01). Similarly, all of the components of the Short Form-36 Health Survey, the Health Assessment Questionnaire scores, and the patient-and physician reported Visual Analogue Scale were significantly improved after training (P < 0.05). Importantly, no clinical evidence or any other self-reported adverse event were found. Laboratory parameters (creatine kinase and aldolase) were also unchanged (P > 0.05) after the intervention. Conclusions: We demonstrated that a 12-week supervised low-intensity resistance training program associated with partial blood flow restriction may be safe and effective in improving muscle strength and function as well as muscle mass and health-related quality of life in patients with PM and DM.
- Prescribed Versus Preferred Intensity Resistance Exercise in Fibromyalgia Pain(2018) RIBEIRO, Roberta P. da Cunha; FRANCO, Tathiane C.; PINTO, Ana J.; PONTES FILHO, Marco A. G.; DOMICIANO, Diogo S.; PINTO, Ana L. de Sa; LIMA, Fernanda R.; ROSCHEL, Hamilton; GUALANO, BrunoExercise is the treatment of choice for fibromyalgia (FM), but little is known about resistance exercise prescription to modulate pain in this condition. This study aimed to compare the effects of different resistance exercise models, comprising self-selected or prescribed intensity, on pain in FM patients. In a cross-over fashion, 32 patients underwent the following sessions: (i) standard prescription (STD; 3 x 10 repetitions at 60% of maximal strength); (ii) self-selected load with fixed number of repetitions (SS); (iii) self-selected load with volume load (i.e., load x sets x repetitions) matched for STD (SS-VM); and (iv) self-selected load with a free number of repetitions until achieving score 7 of rating perceived exertion (SS-RPE). Pain, assessed by Visual Analogic Scale (VAS) and Short-Form McGill Pain Questionnaire (SF-MPQ), was evaluated before and 0, 24, 48, 72, and 96 h after the sessions. Load was significantly lower in SS, SS-VM, SS-RPE than in STD, whereas rating perceived exertion and volume load were comparable between sessions. VAS scores increased immediately after all sessions (p < 0.0001), and reduced after 48, 72, 96 h (p < 0.0001), remaining elevated compared to prevalues. SF-MPQ scores increased immediately after all exercise sessions (p = 0.025), then gradually reduced across time, reaching baseline levels at 24 h. No significant differences between sessions were observed. Both prescribed and preferred intensity resistance exercises failed in reducing pain in FM patients. The recommendation that FM patients should exercise at preferred intensities to avoid exacerbated pain, which appears to be valid for aerobic exercise, does not apply to resistance exercise.
- The Liposuction-Induced Effects on Adiponectin and Selected Cytokines Are Not Affected by Exercise Training in Women(2014) SOLIS, Marina Yazigi; ARTIOLI, Guilherme Giannini; MONTAG, Eduardo; PAINELLI, Vitor de Salles; SAITO, Fabio Lopes; LIMA, Fernanda Rodrigues; ROSCHEL, Hamilton; GUALANO, Bruno; LANCHA JUNIOR, Antonio Herbert; BENATTI, Fabiana BragaIt has been suggested that the abrupt liposuction-induced decrease in adipose tissue could affect adipokine secretion pattern. We hypothesized that exercise training could positively impact adipokine metabolism following liposuction. The aim of this study was to investigate the effects of liposuction on inflammation-related adipokines in women who were either exercise-trained or remained sedentary after surgery. Thirty-six healthy normal-weight women underwent an abdominal liposuction and two months after surgery were randomly allocated into two groups: trained (TR, n = 18, four-month exercise program) and nontrained (NT, n = 18). Inflammation-related adipokine serum levels (TNF-alpha, IL-6, IL-10, and adiponectin) and abdominal and thigh subcutaneous adipose tissue (scAT) mRNA levels were assessed before (PRE) and six months after surgery (POST6). TNF-alpha, IL-6, and IL-10 serum levels were unchanged in both groups. In contrast, TNF-alpha, IL-6, and IL-10 mRNA levels in scAT were increased, whereas adiponectin scAT mRNA and serum levels were decreased at POST6 (P < 0.05, main effect for time). No changes were observed in mRNA levels of MCP-1, CD14, and CD68 in any of the groups. In conclusion, liposuction downregulates adiponectin scAT gene expression and serum levels and upregulates scAT gene expression of inflammation-related genes six months after surgery in normal-weight women, irrespective of exercise training.
- Creatine Supplementation Associated or Not with Strength Training upon Emotional and Cognitive Measures in Older Women: A Randomized Double-Blind Study(2013) ALVES, Christiano Robles Rodrigues; MEREGE FILHO, Carlos Alberto Abujabra; BENATTI, Fabiana Braga; BRUCKI, Sonia; PEREIRA, Rosa Maria R.; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; ROSCHEL, Hamilton; GUALANO, BrunoPurpose: To assess the effects of creatine supplementation, associated or not with strength training, upon emotional and cognitive measures in older woman. Methods: This is a 24-week, parallel-group, double-blind, randomized, placebo-controlled trial. The individuals were randomly allocated into one of the following groups (n=14 each): 1) placebo, 2) creatine supplementation, 3) placebo associated with strength training or 4) creatine supplementation associated with strength training. According to their allocation, the participants were given creatine (4 x 5 g/d for 5 days followed by 5 g/d) or placebo (dextrose at the same dosage) and were strength trained or not. Cognitive function, assessed by a comprehensive battery of tests involving memory, selective attention, and inhibitory control, and emotional measures, assessed by the Geriatric Depression Scale, were evaluated at baseline, after 12 and 24 weeks of the intervention. Muscle strength and food intake were evaluated at baseline and after 24 weeks. Results: After the 24-week intervention, both training groups (ingesting creatine supplementation and placebo) had significant reductions on the Geriatric Depression Scale scores when compared with the non-trained placebo group (p = 0.001 and p = 0.01, respectively) and the non-trained creatine group (p < 0.001 for both comparison). However, no significant differences were observed between the non-trained placebo and creatine (p = 0.60) groups, or between the trained placebo and creatine groups (p = 0.83). Both trained groups, irrespective of creatine supplementation, had better muscle strength performance than the non-trained groups. Neither strength training nor creatine supplementation altered any parameter of cognitive performance. Food intake remained unchanged. Conclusion: Creatine supplementation did not promote any significant change in cognitive function and emotional parameters in apparently healthy older individuals. In addition, strength training per se improved emotional state and muscle strength, but not cognition, with no additive effects of creatine supplementation.
- Rearfoot alignment and medial longitudinal arch configurations of runners with symptoms and histories of plantar fasciitis(2011) RIBEIRO, Ana Paula; TROMBINI-SOUZA, Francis; TESSUTTI, Vitor; LIMA, Fernanda Rodrigues; SACCO, Isabel de Camargo Neves; JOAO, Silvia Maria AmadoOBJECTIVE : To evaluate and compare rearfoot alignment and medial longitudinal arch index during static postures in runners, with and without symptoms and histories of plantar fasciitis (PF). INTRODUCTION: PF is the third most common injury in runners but, so far, its etiology remains unclear. In the literature, rearfoot misalignment and conformations of the longitudinal plantar arch have been described as risk factors for the development of PF. However, in most of the investigated literature, the results are still controversial, mainly regarding athletic individuals and the effects of pain associated with these injuries. METHODS: Forty-five runners with plantar fasciitis (30 symptomatic and 15 with previous histories of injuries) and 60 controls were evaluated. Pain was assessed by a visual analogue scale. The assessment of rearfoot alignment and the calculations of the arch index were performed by digital photographic images. RESULTS: There were observed similarities between the three groups regarding the misalignments of the rearfoot valgus. The medial longitudinal arches were more elevated in the group with symptoms and histories of PF, compared to the control runners. CONCLUSIONS: Runners with symptoms or histories of PF did not differ in rearfoot valgus misalignments, but showed increases in the longitudinal plantar arch during bipedal static stance, regardless of the presence of pain symptoms.
- A randomized controlled trial to reduce sedentary time in rheumatoid arthritis: protocol and rationale of the Take a STAND for Health study(2020) PINTO, Ana Jessica; PECANHA, Tiago; MEIRELES, Kamila; BENATTI, Fabiana Braga; BONFIGLIOLI, Karina; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; PEREIRA, Rosa Maria Rodrigues; IRIGOYEN, Maria Claudia Costa; TURNER, James Edward; KIRWAN, John P.; OWEN, Neville; DUNSTAN, David W.; ROSCHEL, Hamilton; GUALANO, BrunoBackground Patients with rheumatoid arthritis spend most of their daily hours in sedentary behavior (sitting), a predisposing factor to poor health-related outcomes and all-cause mortality. Interventions focused on reducing sedentary time could be of novel therapeutic relevance. However, studies addressing this topic remain scarce. We aim to investigate the feasibility and efficacy of a newly developed intervention focused on reducing sedentary time, and potential clinical, physiological, metabolic and molecular effects in rheumatoid arthritis. Methods The Take a STAND for Health study is a 4-month, parallel-group, randomized controlled trial, in which postmenopausal patients with rheumatoid arthritis will set individually tailored, progressive goals to replace their sedentary time with standing and light-intensity activities. Patients will be recruited from the Clinical Hospital (School of Medicine, University of Sao Paulo) and will be assessed at baseline and after a 4-month follow up. Outcomes will include objectively measured sedentary behavior (primary outcome) and physical activity levels, clinical parameters, anthropometric parameters and body composition; aerobic fitness, muscle function, blood pressure, cardiovascular autonomic function, vascular function and structure, health-related quality of life, and food intake. Blood and muscle samples will be collected for assessing potential mechanisms, through targeted and non-targeted approaches. Discussion Findings will be of scientific and clinical relevance with the potential to inform new prescriptions focused on reducing sedentary behavior, a modifiable risk factor that thus far has been overlooked in patients with rheumatoid arthritis.
- Cardiac autonomic impairment and chronotropic incompetence in fibromyalgia(2011) RIBEIRO, Roberta Potenza da Cunha; ROSCHEL, Hamilton; ARTIOLI, Guilherme Gianini; DASSOUKI, Thalita; PERANDINI, Luiz Augusto; CALICH, Ana Luisa; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; BONFA, Elosa; GUALANO, BrunoIntroduction: We aimed to gather knowledge on the cardiac autonomic modulation in patients with fibromyalgia (FM) in response to exercise and to investigate whether this population suffers from chronotropic incompetence (CI). Methods: Fourteen women with FM (age: 46 +/- 3 years; body mass index (BMI): 26.6 +/- 1.4 kg/m(2)) and 14 gender-, BMI- (25.4 +/- 1.3 kg/m(2)), and age-matched (age: 41 +/- 4 years) healthy individuals (CTRL) took part in this cross-sectional study. A treadmill cardiorespiratory test was performed and heart-rate (HR) response during exercise was evaluated by the chronotropic reserve. HR recovery (deltaHRR) was defined as the difference between HR at peak exercise and at both first (deltaHRR1) and second (deltaHRR2) minutes after the exercise test. Results: FM patients presented lower maximal oxygen consumption (VO2 max) when compared with healthy subjects (22 +/- 1 versus CTRL: 32 +/- 2 mL/kg/minute, respectively; P < 0.001). Additionally, FM patients presented lower chronotropic reserve (72.5 +/- 5 versus CTRL: 106.1 +/- 6, P < 0.001), deltaHRR1 (24.5 +/- 3 versus CTRL: 32.6 +/- 2, P = 0.059) and deltaHRR2 (34.3 +/- 4 versus CTRL: 50.8 +/- 3, P = 0.002) than their healthy peers. The prevalence of CI was 57.1% among patients with FM. Conclusions: Patients with FM who undertook a graded exercise test may present CI and delayed HR recovery, both being indicative of cardiac autonomic impairment and higher risk of cardiovascular events and mortality.
- A randomized clinical trial on the effects of exercise on muscle remodelling following bariatric surgery(2021) GIL, Saulo; KIRWAN, John P.; MURAI, Igor H.; DANTAS, Wagner S.; MEREGE-FILHO, Carlos Alberto Abujabra; GHOSH, Sujoy; SHINJO, Samuel K.; PEREIRA, Rosa M. R.; TEODORO, Walcy R.; FELAU, Sheylla M.; BENATTI, Fabiana B.; SA-PINTO, Ana L.; LIMA, Fernanda; CLEVA, Roberto; SANTO, Marco Aurelio; GUALANO, Bruno; ROSCHEL, HamiltonBackground Muscle atrophy and strength loss are common adverse outcomes following bariatric surgery. This randomized, controlled trial investigated the effects of exercise training on bariatric surgery-induced loss of muscle mass and function. Additionally, we investigated the effects of the intervention on molecular and histological mediators of muscle remodelling. Methods Eighty women with obesity were randomly assigned to a Roux-en-Y gastric bypass (RYGB: n = 40, age = 42 +/- 8 years) or RYGB plus exercise training group (RYGB + ET: n = 40, age = 38 +/- 7 years). Clinical and laboratory parameters were assessed at baseline, and 3 (POST3) and 9 months (POST9) after surgery. The 6 month, three-times-a-week, exercise intervention (resistance plus aerobic exercise) was initiated 3 months post-surgery (for RYGB + ET). A healthy, lean, age-matched control group was recruited to provide reference values for selected variables. Results Surgery resulted in a similar (P = 0.66) reduction in lower-limb muscle strength in RYGB and RYGB+ET (-26% vs. -31%), which was rescued to baseline values in RYGB + ET (P = 0.21 vs. baseline) but not in RYGB (P < 0.01 vs. baseline). Patients in RYGB+ET had greater absolute (214 vs. 120 kg, P < 0.01) and relative (2.4 vs. 1.4 kg/body mass, P < 0.01) muscle strength compared with RYGB alone at POST9. Exercise resulted in better performance in timed-up-and-go (6.3 vs. 7.1 s, P = 0.05) and timed-stand-test (18 vs. 14 repetitions, P < 0.01) compared with RYGB. Fat-free mass was lower (POST9-PRE) after RYBG than RYGB + ET (total: -7.9 vs. -4.9 kg, P < 0.01; lower-limb: -3.8 vs. -2.7 kg, P = 0.02). Surgery reduced Types I (similar to - 21%; P = 0.99 between-group comparison) and II fibre cross-sectional areas (similar to - 27%; P = 0.88 between-group comparison), which were rescued to baseline values in RYGB+ET (P > 0.05 vs. baseline) but not RYGB (P > 0.01 vs. baseline). RYGB + ET showed greater Type I (5187 vs. 3898 mu m(2), P < 0.01) and Type II (5165 vs. 3565 mu m(2), P < 0.01) fCSA than RYGB at POST9. RYGB + ET also resulted in increased capillarization (P < 0.01) and satellite cell content (P < 0.01) than RYGB at POST9. Gene-set normalized enrichment scores for the muscle transcriptome revealed that the ubiquitin-mediated proteolysis pathway was suppressed in RYGB + ET at POST9 vs. PRE (NES: -1.7; P < 0.01), but not in RYGB. Atrogin-1 gene expression was lower in RYGB + ET vs. RYGB at POST9 (0.18 vs. 0.71-fold change, P < 0.01). From both genotypic and phenotypic perspectives, the muscle of exercised patients resembled that of healthy lean individuals. Conclusions This study provides compelling evidence-from gene to function-that strongly supports the incorporation of exercise into the recovery algorithm for bariatric patients so as to counteract the post-surgical loss of muscle mass and function.
- BLOOD FLOW RESTRICTED RESISTANCE TRAINING ATTENUATES MYOSTATIN GENE EXPRESSION ON A PATIEINIT WITH ONCLUSION BODY MYOSITIS(2014) SANTOS, A. R.; NEVES JR., M. T.; GUALANO, B.; LAURENTINO, G. C.; JR, A. H. Lancha; UGRINOWITSCH, C.; LIMA, F. R.; AOKI, M. S.Inclusion body myositis is a rare idiopathic inflammatory myopathy that produces extreme muscle weakness. Blood flow restricted resistance training has been shown to improve muscle strength and muscle hypertrophy in inclusion body myositis. Objective: The aim of this study was to evaluate the effects of a resistance training programme on the expression of genes related to myostatin (MSTN) signalling in one inclusion body myositis patient. Methods: A 65-year-old man with inclusion body myositis underwent blood flow restricted resistance training for 12 weeks. The gene expression of MSTN, follistatin, follistatin-like 3, activin II B receptor, SMAD-7, MyoD, FOXO-3, and MURF-2 was quantified. Results: After 12 weeks of training, a decrease (25%) in MSTN mRNA level was observed, whereas follistatin and follistatin-like 3 gene expression increased by 40% and 70%, respectively. SMAD-7 mRNA level was augmented (20%). FOXO-3 and MURF-2 gene expression increased by 40% and 20%, respectively. No change was observed in activin II B receptor or MyoD gene expression. Conclusions: Blood flow restricted resistance training attenuated MSTN gene expression and also increased expression of myostatin endogenous inhibitors. Blood flow restricted resistance training evoked changes in the expression of genes related to MSTN signalling pathway that could in part explain the muscle hypertrophy previously observed in a patient with inclusion body myositis.
