Background and Objective: Physical activities affect on antioxidative pathway. Varity, period and intensity of activities are important in health improvement. This study was carried out to determine the effect of short and medium periods of high intensities aerobic training on serum level of superoxide dismutase (SOD) and Catalase (CAT) enzymes in female rats. Methods: In this experimental study, 45 Sprague Dawley female rats were randomly allocated into control, short (4 weeks) and medium (8 weeks) of high intensities aerobic training groups. The exercise program was performed on 5 session in each week with speed of 10-17 meters per minute in slope range (5

Background and Objective: There are controversial reports about the effect of training on serum level of visfatin and TNF-α Cytokine .This study was done to evaluate the effect of 8 weeks of aerobic training on serum level of visfatin and TNF-α in non-athletic young women. Methods: In this quasi-experimental study, thirty non-athletic healthy women were non-randomly based on the weight, height, BMI index and body fat percentage divided into two control and training groups. In the training group 8 weeks of aerobic exercise on a stationary bicycle 3 times a week was performed. Serum level of visfatin and TNF-α was measured using ELISA method, prior and at the end of 8th week of training while the subjects were fasted for 12-14 hours. Results: At the end of 8 weeks of aerobic exercise, serum level of visfatin and TNF-α significantly reduced in the training group in comparison with controls (P<0.05). Conclusion: Eight weeks of aerobic training reduces visfatin and TNF-α serum level in non-athletic healthy women.

Background and Objective: Alpha lipoic acid (ALA) is a powerful biological antioxidant which is involved in metabolism and energy production as a co-factor in mitochondrial dehydrogenase enzyme complex. This study was done to evaluate the effect of aerobic exercise and alpha lipoic acid supplement on insulin resistance in females with type 2 diabetes. Methods: In this quasi-experimental study, 44 females with type 2 diabetes divided into four groups including: control, supplementation, training and supplementation + training groups. Patients of supplementation and complex (supplementation + training) groups took three 100mg ALA capsules per day for eight weeks. The training program consisted of 8 weeks and three sessions per week. In each session, the subjects warmed up for 10-15 minutes, ran on a treadmill with the intensity of 40-50% of maximum heart rate for 30 minutes and then cooled down for 5-10 minutes. Blood samples were taken after 12-14 hours fasting in two stages - the beginning and the end of the eighth week. Results: Eight weeks of taking ALA supplements significantly reduced patients' insulin resistance (P<0.05). Eight weeks of running on a treadmill with an intensity of 40-50% of maximum heart rate non-significantly reduced insulin resistance in the training group compared to the controls. In the supplementation + training group a significant reduction of insulin resistance was observed (P<0.05). Conclusion: Alpha lipoic acid supplementation reduces insulin and insulin resistance. While, reduction in fasting blood glucose level causes reduction in insulin resistance in the combination of supplementation and training.

Background and Objective: Diabetes mellitus is the most common type of metabolic diseases which is characterized with hyperglycemia due to implicit or relative insulin deficiency. Diabetes mellitus is acutely related to obesity. Agouti-related protein (AGRP) has 132 amino acids and increases appetite in humans. This study was done to determine the effect of eight weeks aerobic exercise on plasma level of agouti-related protein, glycated hemoglobin and glucose in non-active type II diabetic women. Methods: In this quasi-experimental study, 30 female diabetic patients were divided into exercise and control groups. The training program was performed 3 sessions a week in course of 8 weeks, each session was last for 60 minutes, and the controls did not have any exercise. The plasma level of agouti-related protein, glycated hemoglobin and glucose were measured. Results: There was no significant alteration in the level of AGRP, HbA1c and glucose in either exercise or control groups. There was no significant relation between AGRP with glucose, AGRP with HbA1c and HbA1c with glucose in the exercise and control groups. Conclusion: Eight weeks of aerobic exercise is not enough for making any changes on plasma level of AGRP, HbA1c and glucose in non-active type II diabetic women.

Background and Objective: Different physical activities affect on anti-oxidative system. Varity, period and intensity of activities are necessary in health improvement. This study was carried out to determine the effect of medium period of progressive anaerobic training on serum level of superoxide dismutase and Catalase in female rats.

Methods: In this experimental study, 30 female rats were randomly allocated into control and anaerobic training groups. The training program lasted for 8 weeks with control (without activity) and anaerobic including 3 sessions in a week with speed of 24-30 meters per minute in slope range (515) for 30 seconds.

Results: Serum level of superoxide dismutase was significantly increased in progressive anaerobic training group (109.1±17.3 U/ml) in compare to controls (98.8±12.8 U/ml) (P<0.05). Serum level of Catalase was 51.2±7.2 and 48.4±4.2 U/ml in control and progressive anaerobic training, respectively. This difference was not significant.

Conclusion: The medium period of progressive anaerobic training influences serum level of superoxide dismutase and Catalase in female rats.

Background and Objective: Physical exercise and nutrition supplements are recommended interventions to reduce cachexia. This study was conducted to determine the effect of resistance training and resveratrol supplementation on muscle regeneration indices of MyoD (myoblast determination protein) and eMHC (embryonic Myosin Heavy Chain) in CT-26 colon cancer mice.
Methods: This experimental study was performed on 20 six-week-old BALB/c mice to which CT-26 tumor was implanted. The mice were divided into four groups of resistance training, resveratrol, combination of resveratrol with resistance training, and control. The resistance training group performed six weeks of progressive resistance training. The resveratrol group received 100 mg/kg resveratrol per day, and the control and resistance training group received the solution of Methyl cellulose through gavage. In gastrocnemius muscle MyoD protein and eMHC level were measured using western blot and ELISA methods, respectively.
Results: eMHC protein in combination of resveratrol with exercise group (4.66±0.25) increased significantly compared to the exercise group (3.46±0.64) (P<0.05). Body weight of mice without tumor (21.50±1.30) in the resistance training group increased significantly compared to other groups (P<0.05). There was no significant difference in the tumor weight of mice and MyoD protein in expermental groups.
Conclusion: Regarding the increasing effect of combination of resveratrol with exercise group compared to resistance training group on eMHC, resveratrol supplementation at higher doses may be recommended along with resistance training to improve muscle regeneration.
