Objective: Obesity is associated with an exacerbated metabolic condition that is mediated through impairing balance in the secretion of some adipo-myokines. Therefore, the objective of the present study was to explore the impact of astaxanthin supplementation in conjunction with a 12-week CrossFit training regimen on some selected adipo-myokines, insulin insensitivity, and serum lipid levels in obese males. Material and Methods: This study is a randomized control trial design; 60 obese males were randomly divided into four groups of 15, including the control group (CG), supplement group (SG), training group (TG), and combined training and supplement group (TSG). The participants were subjected to 12 weeks of astaxanthin (AST) supplementation [20 mg/d capsule, once/d] or CrossFit training or a combination of both interventions. The training regimen comprised 36 sessions of CrossFit, each lasting 60 min, conducted three times per week. The metabolic indices, body composition, anthropometrical, cardio-respiratory, and also some plasma adipo-myokine factors, including decorin (DCN), activin A, myostatin (MST), transforming growth factor (TGF)-β1, and follistatin (FST), were examined 12 and 72 h before the initiation of the main interventional protocols, and then 72 h after the final session of the training protocol. Results: There was no significant difference in the baseline data between the groups (p > 0.05). There were significant interactions between group x time for DCN (η² = 0.82), activin A (η² = 0.50), FST (η² = 0.92), MST (η² = 0.75), and TGFB-1 (η² = 0.67) (p < 0.001 for all the variables). Significantly changes showed for DCN in TSG compared to TG and SG and also TG compared to SG (p = 0.0001); for activin A in SG compared to TG (p = 0.01) and TSG (p = 0.002); for FST in SG compared to TG and TSG (p = 0.0001), also in TSG compared to TG (p = 0.0001); for MST in SG, TG, and TSG compared to CG (p = 0.0001) and also in TSG compared to SG (p = 0.0001) and TG (p = 0.001); for TGFB-1 in SG, TG, and TSG compared to CG (p = 0.0001) and also TSG compared to SG (p = 0.0001) and TG (p = 0.001). Conclusions: The 12-week CrossFit training concurrent with AST supplementation reduced anthropometric and metabolic factors and also serum lipid levels while producing positive changes in body composition and cardiovascular factors. Increased FST and DCN and reduced activin A, MST, and TGF-β1 were other affirmative responses to both interventions.

Background: The present study aimed to compare the effects of three therapeutic methods, including regular aerobic training, hyaluronic acid (HA), and mesenchymal stem cells, on Wnt/β-catenin signaling of cardiac tissue in rats with the experimental model of knee osteoarthritis. Methods: Sixty-three male rats were divided into nine groups (seven in each group): (1) healthy control, (2) patient control, (3) sham, (4) saline, (5) exercise (EXT), (6) mesenchymal stem cells (MSCs), (7) hyaluronic acid, (8) EXT + MSCs, and (9) EXT + HA. After inducing the osteoarthritis (OA) model, we conducted 5 days of running on the treadmill for five weeks for the EXT group. Also, HA was injected intra-articularly. After 12 to 14 hours of fasting and 72 hours following the last training session, we conducted cardiac tissue sampling for β-catenin, GSK-3β, Wnt, Fz, TCF, and DKK1 analysis. We used RT-PCR to analyze the expression of the β-catenin, GSK-3β, Wnt, Fz, TCF, and DKK1 genes in cardiac tissue. The data were analyzed using one-way ANOVA and Tukey's post hoc test (P < 0.05). Results: Osteoarthritis induction significantly decreased the expression of the GSK-3β and DKK1 genes but significantly increased the expression of the β-catenin, Wnt, Fz, and TCF genes of cardiac tissue compared to the control group. However, the EXT, HA, MSC, and combination methods increased the expression of the GSK-3β and DKK1 genes but decreased the expression of the β-catenin, Wnt, Fz, and TCF genes of cardiac tissue, which were significant in the combination group. Conclusions: Regular exercise, along with HA and MSCs, may have protective effects for the following reasons: (1) reducing the expression of the β-catenin, Wnt, Fz, and TCF genes; (2) increasing the expression of the GSK-3β and DKK1 genes in cardiac tissue; and (3) inhibiting Wnt signaling in the heart.

Background: Oxidative stress harms cells and impairs the balance between oxidative and antioxidative factors. Exercise and capsaicin have anti-inflammatory and antioxidant effects, as well as some benefits on the cardiovascular system. Objectives: The aim of the present study was to examine the effect of aerobic training with capsaicin on heart changes oxidative stress in rats fed a high-fat diet (HFD). Methods: In this experimental study, 40 male Wistar rats were fed a normal diet (ND, n = 8) or HFD (n = 32) for 8 weeks. After eight weeks, all rats were divided into five groups: ND, HFD, high-fat diet-training (HFDT), high-fat diet-capsaicin (HFDCap), high-fat diet-training-capsaicin (HFDTCap). Training groups performed a progressive aerobic running program (at 15 - 25 m/min, 30 - 60 min/day, and 5 days/week) on a motor-driven treadmill for eight weeks. Capsaicin (4 mg/kg/day) was administered orally, by gavage, once a day. Results: The results showed significant increase in cardiac SOD, GPx and CAT levels in HFDT (P < 0.001), HFDCap (P < 0.001) and HFDTCap (P < 0.001) groups. Also, a significant increase in the amount of this index was observed in the HFDTCap compared to the HFDT and HFDCap groups (P < 0.05). The level of malondialdehyde (MDA) in all experimental groups was significantly lower than the HFD group (P < 0.001). Conclusions: Exercise and capsaicin improve HFD-induced oxidative stress. Therefore, exercise and capsaicin can be used as an appropriate alternative treatment for obesity and its associated inflammatory and oxidative effects.

Background: Volleyball requires high anaerobic and aerobic capacity, so to evaluate this important issue, there are various tests such as Bruce maximal test. There is no standard field test to measure cardiovascular function for women volleyball according to exercise mode. Objectives: This study aimed to design and validation of functional cardiorespiratory exercise field tests in women volleyball players. Methods: In a diagnostic value study, 64 competitive female volleyball players with three years of playing experience (Age: 27 ± 6) were voluntarily selected from Tehran’s first division league. To evaluate VO2max, the Bruce test and the newly designed test, which was fully explained in the methodology section, were used. Data were analyzed using the ROC curve test. Results: The results showed that the area under the curve exceeded 0.71%, and the sensitivity and specificity values were 70.8% and 75%, respectively. The PPV obtained in this study was 89.5, and also the NPV values were 46.2, indicating relatively good reliability for screening. Conclusions: The present study shows that the newly designed test for women volleyball players, which uses a special exercise mode in modeled volleyball, has relatively good reliability. This test may be used as an efficient and inexpensive field test to measure the VO2max in women volleyball players.

Purpose Pathological hypertrophy of heart tissue has been attributed to changes in some microRNAs and their target genes in heart tissue. This study intended to study the effects of eight weeks of moderate and high intensity aerobic training (MIT&HIT) on the mRNA of Mir-145, Wnt3a, and Dab2 in heart tissue of type 2 diabetic rats. Methods To implement this experimental research, 60 male Wistar rats were randomly divided into 6 groups, including Healthy-control (HC), Diabetic-control (DC), Moderate intensity training (MIT), Diabetes-MIT (DMIT), high intensity training (HIT) and Diabetes-HIT (DHIT). The aerobic training was conducted with moderate (50–60% VO2max) and high (85–90% VO2max) intensity, 5 days a week, for 8 weeks. The Mir-145, Wnt3a and Dab2 gene expression in the heart tissue samples was measured by Real Time PCR. Data were analyzed by one-way ANOVA and Tukey post hoc test at the P < 0.05. Results Moderate and high intensity aerobic training was associated with non-significant increase in Mir-145 mRNA of Heart tissue in type 2 diabetic rats than the diabetic control group(P < 0.05). Moderate and high intensity aerobic training was associated with significant increase in Wnt3a mRNA (P = 0.001) and significant decrease in Dab-2 mRNA (P = 0.001) of Heart tissue in type 2 diabetic rats than the diabetic control group. The Dab-2 mRNA was significantly lower of heart tissue in the diabetes- high intensity training group than the diabetes- moderate intensity training group (P = 0.001). Conclusion It seems that moderate and high intensity aerobic exercise can help regulate the genes of the physiological hypertrophy pathway of the heart tissue in diabetes.

Introduction: The aim of this study was to investigate the effect of endurance training and stem cell injection on FGF2 and MMP13 gene expression in knee tissue of rats with knee osteoarthritis. Methods: The type of study was an experimental one.Male Wistar rats were randomly divided into 5 groups: control - healthy, control - patient, patient - stem cell, patient - training, and patient - training - stem cell. The training program consisted of 30 minutes of running on a treadmill with no slope at 16 m / min for the first week, with 1 m / min added weekly. Rats received MSCs through intracellular injection of 1*106 cells / kg. Expression of FGF2 and MMP13 genes was measured by Real Time PCR. One way ANOVA and if there was a significant difference, Tukey post hoc test were used to determine the difference between groups. All statistical analyzes were performed using SPSS version 20. Results: Data analysis showed that training and stem cell therapy have significantly increased in genes expression of FGF2 and MMP-13 in mice with osteoarthritis (p <0.000). Moreover, Tukey post hoc test showed a significant difference in the level of FGF2 changes in the training-stem cell groups compared to the training group and the saline group (p=0.000‌). There was also a significant difference between the MMP-13 follow-up test with the control group with the saline group, the training group and the stem cell with the train-stem cell, and the saline group with the training group9(P=0.000‌). Conclusion: The results showed that FGF2 levels and MMP13 in the cartilage tissue of mice with osteoarthritis have increased and endurance training and stem cells therapy caused a decrease in the level of factors.
