    Exercise training can attenuate the inflammatory milieu in women with systemic lupus erythematosus
    (2014) PERANDINI, Luiz A.; SALES-DE-OLIVEIRA, Diego; MELLO, Suzana B. V.; CAMARA, Niels O.; BENATTI, Fabiana B.; LIMA, Fernanda R.; BORBA, Eduardo; BONFA, Eloisa; SA-PINTO, Ana L.; ROSCHEL, Hamilton; GUALANO, Bruno
    Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by chronic inflammation. This study sought to assess the effects of an exercise training program on cytokines and soluble TNF receptors (sTNFRs) in response to acute exercise in SLE women. Eight SLE women and 10 sex-, age-, and body mass index-comparable healthy controls (HC) participated in this study. Before and after a 12-wk aerobic exercise training program, cytokines and sTNFRs were assessed at rest and in response to single bouts of acute moderate/intense exercise. HC performed the acute exercise bouts only at baseline. After the exercise training program, there was a decrease in resting TNFR2 levels (P = 0.025) and a tend to reduction interleukin (IL)-10 levels (P = 0.093) in SLE. The resting levels of IL-6, IL-10, and TNF-alpha after the exercise training in SLE reached HC levels (P > 0.05). In response to a single bout of acute moderate exercise, the area under the curve (AUC) of IL-10 was significantly reduced after the exercise training program in SLE (P = 0.043), and the AUC of IL-10, IL-6, TNF-alpha, and sTNFR1 of SLE approached control values (P = 0.05). In response to a single bout of acute intense exercise, the AUC of IL-10 was significantly reduced in SLE (P = 0.015). Furthermore, the AUC of sTNFR2 tended to decrease after exercise training program in SLE (P = 0.084), but it did not reach control values (P = 0.001). An aerobic exercise training program attenuated the inflammatory milieu in SLE women, revealing a novel homeostatic immunomodulatory role of exercise in an autoimmunity condition.

    (2011) NEVES JR., Manoel; GUALANO, Bruno; ROSCHEL, Hamilton; LIMA, Fernanda Rodrigues; SA-PINTO, Ana Lucia de; SEGURO, Antonio Carlos; SHIMIZU, Maria Heloisa; SAPIENZA, Marcelo Tatit; FULLER, Ricardo; LANCHA JR., Antonio Herbert; BONFA, Eloisa
    We aimed to investigate whether creatine supplementation affects the measured glomerular filtration rate in postmenopausal women (age, 58 +/- 3 years). Subjects were randomly assigned to receive either creatine (20 g(.)day(-1) for 1 week and 5 g(.)day(-1) thereafter) or a placebo. Kidney function was assessed at baseline and after 12 weeks. [Cr-51] EDTA clearance remained unchanged (CR-PRE: 86.16 +/- 14.36 mL(.)min(-1) per 1.73 m(2), POST: 87.25 +/- 17.60 mL(.)min(-1) per 1.73 m(2); PL-PRE: 85.15 +/- 8.54 mL(.)min(-1) per 1.73 m(2), POST: 87.18 +/- 9.64 mL(.)min(-1) per 1.73 m(2); p = 0.81). Thus, we concluded that creatine supplementation does not affect glomerular filtration rate in postmenopausal women.

    Beta-alanine Supplementation Increases Muscle Carnosine Content And Physical Capacity In Elderly Subjects
    (2012) FAVERO, Serena del; ROSCHEL, Hamilton; SOLIS, Marina Y.; HAYASHI, Ana P.; ARTIOLI, Guilherme G.; OTADUY, Maria Concepcion; BENATTI, Fabiana B.; HARRIS, Roger C.; WISE, John A.; LEITE, Claudia C.; PEREIRA, Rosa M.; SA-PINTO, Ana L. de; LANCHA-JUNIOR, Antonio Herbert; GUALANO, Bruno
    PURPOSE: To investigate the effects of beta-alanine supplementation on exercise performance capacity and on the muscle carnosine content in elderly subjects. METHODS: Eighteen elderly subjects (65 ± 4 yrs) were randomly assigned to receive either beta-alanine (BA, n=12) or placebo (PL, n=6) for 12 weeks. The BA group received 3.2g of betaalanine per day (2x800mg, given 2 times per day). The PL group received the exact same amount of placebo. At baseline (PRE) and after 12 weeks (POST-12) of supplementation we assessed the muscle carnosine content and anaerobic exercise capacity. Food intake was monitored throughout the study. RESULTS: A significant increase in the muscle carnosine content of the gastrocnemius muscle was found in the BA group (+ 85.4%) when compared with the PL group (+ 7.2%) (p=0.004; ES: 1.21). The time-to-exhaustion in the TLIM test was significantly improved (p=0.05; ES: 1.71) in the BA group (+36.5%) versus the PL group (+8.6%). Similarly, time-to-exhaustion in the incremental test was also significantly increased (p=0.04; ES: 1.03) following beta-alanine supplementation (+12.2%) when compared with placebo (+0.1%). We also observed significant positive correlations between the relative change in the muscle carnosine content and the relative change in the time-to-exhaustion in the TLIM test (r=0.62; p = 0.01) and in the incremental test (r=0.48; p = 0.02). Dietary intake was unchanged. CONCLUSION: beta-alanine supplementation is effective in increasing the muscle carnosine content in healthy elderly subjects, with subsequent improvement in their exercise capacity.

    (2014) ALVES, Christiano Robles Rodrigues; MEREGE FILHO, Carlos Alberto Abujabra; JANNING, Paulo Roberto; BECHARA, Luiz Roberto Grassmann; AZEVEDO, Rafael de Almeida; BENATTI, Fabiana Braga; PEREIRA, Rosa Maria Rodrigues; PINTO, Ana Lúcia de Sá; BRUM, Patrícia Chakur; GUALANO, Bruno
    The aim of this study was to evaluate the effects of creatine supplementation associated or not with strength training upon lipid peroxidation in older women. This was a clinical, randomized, double-blind, placebo-controlled trial. Older women were randomly allocated into four groups: 1) placebo supplementation (PL, n = 10), 2) creatine supplementation (CR; n = 10), 3) placebo supplementation associated with strength training (PL + RT, n = 6) and 4) creatine supplementation associated with strength training (CR + RT, n = 8). Before (PRE) and after 24 weeks (POST), blood samples were collected to measure lipid hydroperoxides concentration by spectrophotometry. No statistical difference was observed on the lipid hydroperoxides concentration between groups (PL: PRE = 48.7 ± 36.9; POST = 29.3 ± 18.8; Δ = -13.0 ± 26.8; CR : PRE = 51.0 ± 46.0; POST = 54.2 ± 51.6; Δ = -8.6 ± 30.2; + PL TR: PRE = 33.0 ± 11.2; POST = 47.3 ± 31.6, Δ = 14.3 ± 39.2; CR + TR: PRE = 18.5 ± 10.1; POST = 28.1 ± 17.9, Δ = 9.7 ± 16.4 pmol.mg-1 of total protein, p = 0.17). Creatine supplementation associated or not with strength training did not affect the lipid peroxidation, an important plasmatic marker of oxidative stress, in elderly women.

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.

    (2011) NEVES JR., Manoel; GUALANO, Bruno; ROSCHEL, Hamilton; FULLER, Ricardo; BENATTI, Fabiana Braga; PINTO, Ana Lucia De Sa; LIMA, Fernanda Rodrigues; PEREIRA, Rosa Maria; LANCHA JR., Antonio Herbert; BONFA, Eloisa
    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 acute aerobic exercise on leukocyte inflammatory gene expression in systemic lupus erythematosus
    (2016) PERANDINI, L. A.; SALES-DE-OLIVEIRA, D.; ALMEIDA, D. C.; AZEVEDO, H.; MOREIRA-FILHO, C. A.; CENEDEZE, M. A.; BENATTI, F. B.; LIMA, F. R.; BORBA, E.; BONFA, E.; SA-PINTO, A. L.; ROSCHEL, H.; CAMARA, N. O.; GUALANO, B.
    Systemic lupus erythematosus (SLE) is an autoimmune disease with a persistent systemic inflammation. Exercise-induced inflammatory response in SLE remains to be fully elucidated. The aim of this study was to assess the effects of acute exercise on leukocyte gene expression in active (SLEACTIVE) and inactive SLE (SLEINACTIVE) patients and healthy controls (HC). Methods: All subjects (n = 4 per group) performed a 30-min single bout of acute aerobic exercise (similar to 70% of VO2 peak) on a treadmill, and blood samples were collected for RNA extraction from circulating leukocyte at baseline, at the end of exercise, and after three hours of recovery. The expression of a panel of immune-related genes was evaluated by a quantitative PCR array assay. Moreover, network-based analyses were performed to interpret transcriptional changes occurring after the exercise challenge. Results: In all groups, a single bout of acute exercise led to the down-regulation of the gene expression of innate and adaptive immunity at the end of exercise (e.g., TLR3, IFNG, GATA3, FOXP3, STAT4) with a subsequent up-regulation occurring upon recovery. Exercise regulated the expression of inflammatory genes in the blood leukocytes of the SLE patients and HC, although the SLE groups exhibited fewer modulated genes and less densely connected networks (number of nodes: 29, 40 and 58; number of edges: 29, 60 and 195; network density: 0.07, 0.08 and 0.12, for SLEACTIVE, SLEINACTIVE and HC, respectively). Conclusion: The leukocytes from the SLE patients, irrespective of disease activity, showed a down-regulated inflammatory gene expression immediately after acute aerobic exercise, followed by an up-regulation at recovery. Furthermore, less organized gene networks were observed in the SLE patients, suggesting that they may be deficient in triggering a normal exercise-induced immune transcriptional response.
