Abstract
ABSTRACT
Background and Objectives: Osteoarthritis (OS) is the most common type of arthritis and joint disease, especially in women. Proinflammatory cytokines, biochemical factors, specially matrix metalloproteinases, and reactive oxygen species play important roles in joint destruction in this disease. Therefore, the present study aimed to evaluate level of inflammatory factors and its relationship with clinical symptoms of OS in female patients.
Methods: The study was performed on female patients with knee OS, referring to healthcare centers of Tabriz University of Medical Sciences. After measuring the weight and height of patients, clinical symptoms such as severity of pain and physical performance were evaluated using the Knee Injury and Osteopaedic Outcome Score questionnaire. Serum levels of IL-1β, TNF-α, and hs-CRP in fasting blood samples were measured using ELISA kits and immunoturbidimetric assays.
Results: There was a significant association between level of IL-1β and score of pain. There was no significant relationship between the clinical symptoms and level of other inflammatory factors.
Conclusion: The results of the present study showed that the increase in inflammatory factors is correlated with severity of pain in OS patients.

Abstract
ABSTRACT
Background and objectives: Studies have shown that exercise can affect hormone secretion and some metabolic and endocrine functions. The aim of this study was to assess the effect of eight weeks of aerobic training on thyroid hormones and quality of life in obese postmenopausal women.
Methods: In this semi-experimental study, 21 obese (body mass index >30 Kg/m2) women aged between 35 and 45 were randomly divided into an experimental (n=10) group and a control group (n=11). The subjects in the experimental group performed 30-60 minutes of aerobic exercise at 65-75% of maximum heart rate, three times a week, for eight weeks. Level of thyroid hormones and quality of life subscales were compared within and between the groups. Statistical analysis was performed at significance level of 0.05.
Results: After the eight-week exercise program, thyroxine, triiodothyronine and thyrotropin releasing hormone levels increased significantly, and thyroid releasing hormone level decreased significantly (P=0.001). The exercise program also had significantly positive effects on quality of life and its occupational, sexual and emotional subscales in obese postmenopausal women.
Conclusion: Aerobic exercise causes a significant increase in levels of thyroxine, triiodothyronine and thyrotropin releasing hormone and some subscales of quality of life. It also causes a significant decrease in thyroid releasing hormone level, which indicates the effect of exercise on hormone secretion.
KEYWORDS: Thyroid hormones, Obese, Quality of life, Aerobic training.

Abstract
Background and objectives: Given the growing prevalence of obesity in children, the present study aimed to investigate effects of continuous and interval aerobic training on insulin resistance index and serum cortisol levels of obese girls.
Methods: The study was performed on 36 healthy girls aged 9-11 years with a body mass index (BMI) of higher than 85th percentile. The subjects were randomly divided into three groups of interval training, continuous training and control. The training groups performed exercises three days a week for eight weeks. The exercises were performed at 70% of VO2max in the first four weeks and at 80% of VO2max in the following weeks. Fasting blood samples were taken 72 hours before the first session and 72 hours after the last training session in order to measure levels of cortisol, glucose, insulin and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR).Weight, BMI and body fat percentage were also measured by conventional methods. Data analysis was performed in SPSS 21 using paired t-test and one-way analysis of variance.
Results: The mean level of BMI and body fat percentage decreased significantly after the interval and continuous training, respectively (P<0.05). The HOMA-IR index did not change significantly in the study groups (P>0.05). The cortisol level increased slightly in the continuous training and control groups (P=0.075) and decreased insignificantly (P=0.131) in the interval training group. There was no difference between the training groups and the control group in terms of HOMA-IR and cortisol levels.
Conclusion: Insulin levels, HOMA-IR showed a decrease trend while a reasonable increase in cortisol level we showed in the continuous training group. BMI level and fat percentage decreased in two both training groups.

Abstract
Background and objectives: Endurance exercise causes fatigue due to mitochondrial dysfunction and oxidative stress. The present study was designed to investigate the effects of taurine supplementation on lipids peroxidation and antioxidant activity during endurance activities.
Methods: Twenty-four male volunteers aged 27 ± 1.8 years and weighting 74.9 ± 5.9 kg were randomly divided into three groups: taurine supplementation (n=8), placebo (n=8), and control (n=8). The subjects completed a 28-day endurance training protocol. Biochemical parameters such as superoxide dismutase (SOD), glutathione peroxidase (GPX) activities, as well as malondialdehyde (MDA) concentrations (8 hours before the first session and 8 hours after the last session) and maximum rate of oxygen consumption, were measured to evaluate the antioxidant, lipid peroxidation, and VO2 max status respectively. Finally, data were analyzed by SPSS software at a significance level of <0.05.
Results: Taurine supplementation significantly increased SOD (p=0.001) and GPX (p=0.001) but significantly decreased MDA (p=0.001). However, it had no significant effect on the VO2 max.
Conclusion: The results of the present study indicate that taurine has antioxidant effects against endurance exercise-induced oxidant stress and lipid peroxidation.
