简要总结
The present study aimed to verify the effects of resistance exercise training and successive detraining on body composition, lipid profile, muscle strength, oxidative stress, and inflammatory markers of postmenopausal breast cancer survivors undergoing tamoxifen treatment.
详细描述
The present study aimed to verify the effects of 12 weeks of resistance exercise training and successive 12 weeks of detraining on body composition (Body Mass, Body Mass Index, Fat Mass, and Fat-Free Mass), lipid profile (Triglycerides, Total Cholesterol, LDL-Cholesterol, HDL-Cholesterol), muscle strength (1RM test), oxidative stress (Thiobarbituric acid reactive substances,Non-Protein Thiols, Catalase activity, and Superoxide Dismutase), and inflammatory markers (Interferon γ, Tumor Necrosis Factor α, interleukin 6 , Adiponectin, and Interleukin 4) of postmenopausal breast cancer survivors undergoing tamoxifen treatment.

结局指标
主要结局
Changes in blood biomarkers (U/gHb)
时间窗: Before and within 72 hours after 12 weeks of exercise training/detraining
Blood samples will be collected after 8-10 hours overnight fasting directly in evacuated tubes containing separator gel. After centrifugation for 10 min at 3000 rpm, the serum will be separated for immediate analysis or stored at -80 °C for further analysis. The activity of superoxide dismutase (SOD) was evaluated based on their ability to inhibit pyrogallol auto-oxidation and promote a decline in absorbance at 420 nm over time. Expressed in U/gHb.
Changes in blood biomarkers (mmol/L)
时间窗: Before and within 72 hours after 12 weeks of exercise training/detraining
Blood samples will be collected after 8-10 hours overnight fasting in evacuated tubes containing separator gel. After 10 min centrifugation at 3000 rpm, the serum will be stored at -80 °C for further analysis. Lipid peroxidation was estimated by determining the serum concentration of thiobarbituric acid reactive substances (TBARS). The TBARS concentration will be obtained by spectrophotometric reading at 535 nm and interpolation in a malondialdehyde calibration curve. Oxidative damage to serum proteins will be estimated by determining the concentration of carbonylated proteins by reading the absorbance at 370 nm and using the molar absorptivity coefficient of 22.000 M-1cm-1. The levels of non-protein thiols will be obtained by the colorimetric method based on the reaction of the sulfhydryl group with 5,5'-dithiobis (2-nitrobenzoic acid) (DTNB). Expressed in mmol/L.
Changes in blood biomarkers (mg/dL)
时间窗: Before and within 72 hours after 12 weeks of exercise training/detraining
Blood samples will be collected after 8-10 hours overnight fasting directly in evacuated tubes containing separator gel. After centrifugation for 10 min at 3000 rpm, the serum will be separated for immediate analysis or stored at -80 °C for further analysis. The serum levels of triglycerides (TGC), total cholesterol (t-C), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) will be determined using commercial kits (Labtest, Lagoa Santa, MG, Brazil) in a Technicon RA-XT biochemical analyzer (Bayer, New York, NY, USA). Expressed in mg/dL.
Changes in blood biomarkers (pg/mL)
时间窗: Before and within 72 hours after 12 weeks of exercise training/detraining
Blood samples will be collected after 8-10 hours overnight fasting directly in evacuated tubes containing separator gel. After centrifugation for 10 min at 3000 rpm, the serum will be separated for immediate analysis or stored at -80 °C for further analysis. Serum levels of IL-4, IL-6, IFN-γ, TNF-α and Adiponectin will be determined by enzyme-linked immunosorbent assays (ELISA) using commercial kits (BD Biosciences, San Jose, CA, USA), according to the manufacturer's instructions, in an Immulite 2000 analyzer (BD Biosciences, San Jose, CA, USA). Expressed in pg/mL.
Changes in blood biomarkers (K/gHb.s)
时间窗: Before and within 72 hours after 12 weeks of exercise training/detraining
Blood samples will be collected after 8-10 hours overnight fasting directly in evacuated tubes containing separator gel. After centrifugation for 10 min at 3000 rpm, the serum will be separated for immediate analysis or stored at -80 °C for further analysis.Catalase (Cat) activity was evaluated by the ability of this enzyme to convert H2O2 into O2 and H2O. Expressed in K/gHb.s.
