Abstract

Background and Objective: Cervical stabilization training is a method of exercise which is designed to improve the mechanisms by which the cervical spine maintains a stable, injury-free state. The aim of this study was to compare effectiveness of muscle stabilization training with dynamic exercises on the chronic neck pain and disability. Materials and Methods: In this double-blind clinical trail study twenty-six patients with chronic neck pain were recruited. Subjects were randomly assigned to either a stabilization (n=13) or a dynamic exercises group (n=13). Before and after intervention, pain was assessed with visual analog scale (ordinal) and Northwick Park Neck Pain Questionnaire (NPNPQ), disability (ordinal) with Neck Disability Index (NDI), neck muscles strength (bar) using Dynatest and cervical ranges of motion (degrees) with specific neck goniometer. A 24 session exercise program which lasted 12 weeks, two sessions per week, and 45 minutes per session was performed for both groups. Independent t-test or Mann-Whitney U and paired t-test or Wilcoxon were used for comparison between the pretreatment and post treatment test results between groups and within groups, respectively. Results: The mean neck pain (NPNPQ) decreased from 18.23±0.77 to 7.54±4.39 in the stabilization group and from 18.31±3.99 to 11.85±3.89 in the dynamic group (P<0.05). The mean disability (NDI) decreased from 22.69±4.99 to 8.23±4.09 in the stabilization group and from 22.23±4.88 to 14.92±5.54 in the dynamic group (P<0.05). After treatment, neck muscles strength and range of extension increased and both neck pain and disability decreased in the stabilization group compared with the dynamic ones (P<0.05). However, there was no significant difference between two groups regarding flexors and left lateral flexors strength and ranges of flexion, right and left lateral flexion. Conclusion: This study showed that neck specific stabilization and dynamic exercises increase, range of motion, decrease pain and disability. Also specific stabilization exercies was more useful than dynamic procedure.

Abstract

Background and Objective: Fibrinogen, an inflammatory marker as well as a fundamental part of the coagulation cascade, is suggested to play a significant role in the pathogenesis of atherosclerosis and complications of atherothrombotic diseases. This study was carried out to assess the comparison of acute aerobic and resistance training method on plasma fibrinogen concentration in young women. Materials and Methods: This semi-experimental study was done on twenty trained volunteer women students, which was selected objectively, and availability. The subjects were randomly divided into two groups of aerobic (n=10) and resistance training (n=10). Aerobic group performed exhaustive workout program on treadmill intensity 65 to75% of Vo2max on treadmill. The resistance group completed three sets of 5-7 repetitions of six exercises at an intensity corresponding to 80% of 1RM. Following 12 to 14 hours of nightly fasting, venous blood samples (5 cc) were collected pre, immediately after exercise and after 60 min of recovery and analyzed for fibrinogen content. Participants were matched according to anthropometric measurements, age, fat percentage and Vo2max. Data tested by using independent t, repeated measures analysis of variance and post-hoc test least significant difference (LSD) (P≤0.05). Results: In both the aerobic and resistance training groups, fibrinogen levels increased immediately after exercise and remained higher than baseline levels during recovery. This changes were significant only in aerobic group (P<0.05). Resistance training increased significantly the fibrinogen levels immediately after exercise than aerobic exercise (P<0.035). Conclusion: It can be concluded that the exhaustive aerobic exercise may induce slightly increase the fibrinogen levels in comparison with resistance training at intensity corresponding to 80% of 1RM.

Abstract

Background and Objective: Adiponectin is an adipocyte-secreted hormone. Low levels of Adiponectin may indicate the insulin resistance and development of diabetes. The regular exercise therapy induces insulin resistance to be reduced. Glucose uptake increase in muscles, increased adiponectin levels and decreased of HbA1c in diabetic patients. This study was designed to evaluated the effect of down-hill and up-hill running exercises on the adiponectin and serum glucose in type-2 diabetic patients. Materials and Methods: This clinical trial study was conducted on 28 patients (13 male and 15 female), age 40 to 60 years, with type-2 diabetes, in neuromuscular rehabilitation research center, Semnan, Iran during 2009. Participants were assigned randomly in one of the two experimental groups, eccentric or concentric exercise using treadmill. Before and after control and intervention period, glucose, HbA1c and adiponectin serum were measured in both groups. Data were analyzed using SPSS-18, Kolmogorov-Smirnov, Repeated Measures ANOVA, Tukey and independent t tests. Results: Eccentric and concentric exercise significantly decreased glucose, HbA1c and also increased adiponectin levels (P<0.05) in type-2 diabetic patients. However, eccentric exercise also significantly reduced glucose and HbA1c and increased adiponectin levels compared to the concentric exercise (P<0.05). Conclusion: This study showed that eccentric exercise are more effective than concentric exercise to reduce and control the blood glucose level and improve serum adiponectin in type-2 diabetes mellitus patients.

Abstract

Free radicals are unstable molecules in reaction with other molecules lead to a variety of injuries and illnesses. However, to prevent the injuries, enzymatic and non-enzymatic antioxidants react with free radical in various forms. Free radicals and antioxidant enzyme acts by various mechanisms, although age, gender and physical activity affects on these reactions. Different responses and adaptation are experienced to oxidative stress among women and men, young, elderly, subjects with physical fitness and untrained subjects. The present article reviewed the effect of oxidative stress due to exercise-induced adaptations.

Abstract

Background and Objective: Accumulating evidence indicates a relation between aerobic capacity and glucose concentration, although the molecular mechanisms of this relationship are not fully known yet. This study was done to determine the effect of effect of 12 weeks aerobic exercise training on aerobic capacity and glucose concentration in obese men. Methods: In this quasi-experimental study, thirty two adult obese males were divided into interventional and control groups. Anthropometrical indexes, fasting blood glucose and insulin, resting heart rate and aerobic capacity (VO2max) were measured before and after a 12 weeks aerobic exercise in the interventional and control groups. Beta cell function was calculated by fasting glucose and insulin. Results: Long time aerobic exercise led to significant reduction in glucose (112±10 vs. 85±11 mg/dl), anthropometrical indces, BMI (28.44±2.29 vs. 33.24±5.14), increase in VO2max (26.12±4.11 vs. 32±6.41 ml/kg/min), beta cell function (83±23 vs. 181±35) and in interventional group in comparision with controls. A significant correlation was found between the changes in VO2max with changes in beta cell function and glucose level, these correlations were independent of BMI. There was no significant change in insulin level between intervention and control groups. Conclusion: Increased aerobic capacity or cardiovascular fitness by exercise training improve beta cell function of glucose concentration in obese men.

Abstract

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.

Abstract

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.

Abstract

Background and Objective: Pregnancy is a period of women’s life which is usually associated with reducing maternal daily physical activity. However, maintaining adequate daily physical activity is important for mother and fetus. This study was conducted to determine the relationship between exercise before and during pregnancy and gestational diabete mellitus (GDM).

Methods: This case-control study was conducted on 80 pregnant women with gestational diabete mellitus and 57 non-diabetic pregnant women. Physical activity during one and eight years before, and first and second trimesters of pregnancy was recorded through interview.

Results: Regular participation in exercise activities in non-diabetic women were significantly more than diabetic women during all periods (P<0.05). Regular participation in exercise during one year before and second trimester of pregnancy was inversely correlated to GDM (P<0.05). Energy expenditure of second trimester of pregnancy was significantly correlated to reduce GDM (P<0.05).

Conclusion: Regular exercise before and during pregnancy can be effective in reducing the probability of GDM. Exercise during one year before and especially second trimester of pregnancy are more important predictors of GDM.

Abstract

Background and Objective: Aging eldely is associated with impaired angiogenesis, glomerulosclerosis and increased susceptibility to nephrotoxic injury. This study was done to compare the independent and combined effect of aerobic exercise and garlic extract on the levels of renal vascular endothelial growth factor (VEGF) and transforming growth factor-β1 (TGF-β1) in eldely rats.

Methods: In this experimental study, 35 aged eldely male Wistar rats were randomly allocated into 5 groups including control, sham, garlic (2.5 g/kg/bw), aerobic exercise, garlic plus exercise. The animals exercised by swimming training at 5 min to 60 min per day, 3 days a week over 8 weeks. Animals in garlic plus exercise were received garlic extract (2.5 g/kg/bw) and swimming training. The renal TGF-β1 and VEGF level were evaluated by ELIZA method.

Results: 8 weeks swimming training, garlic supplementation and the combined intervention were associated with a significant increased the renal VEGF and reduced TGF-β1 level (P<0.05). There was no difference between swimming training, garlic supplementation and garlic plus exercise on renal VEGF and TGF-β1 levels in aged rats.

Conclusion: It seems that the protective role of regular swimming training, garlic supplementation and the combined intervention in the renal aging process meight in part be related to their ability to attenuate TGF- β1 and up regulating VEGF.
