Abstract
Background: Premenstrual syndrome is one of the most incidencial problems in
women’s during reproductive age. That effect personal performance in family and society
status. Varied therapeutic treatment has been studied for its promotion. The main
attention was to find a method without complications. This study performed with aim of
assessing effect of one period of continuous aerobic exercise on premenstrual syndrome
in 18-25 years female students in jahrom medical school.
Methods: This study was a kind of semi experimental study with two group plane. Forty
students were assessed for premenstrual syndrome with regular mense, without previous
history of Diabetes mellitus and Thyroid, Gynecologic and psychological disease.
Twenty subjects (with similar VO2 MAX) were selected and randomly divided to two
experimental and control groups. Data gathering was from ILPDD questionnaire
concluded 11 question about signs and symptoms of mental and physical complain
related to premenstrual syndrome that filled by samples. All samples have positive five
complain that four of them depend on mental symptoms of premenstrual syndrome.
Intensity of quantity of premenstrual syndrome and levels of estrogen and progesterone
were measured. Then, exercise regime including continuous aerobic exercise, were
performed for eight weeks, with frequency of three sessions every week. At the end of 8th
week, posttests were repeated in the situation similar to pretest. Analytic statistic as a
Nonparametric Mann-whitney test, and nonparametric Wilcoxon signed ranks test was
used for comparing variables.
Results: This study showed that after two method of aerobic exercise, somatic and
effective complain was decrease in case group (p>0.05). Hormonal change in two groups
was not significant.
Conclusion: Releaving aerobic experiences is effective for somatic and affective
complains secondary to premenstrual syndrome and this plan can be replace by other
methods of medical management.

Abstract
Background: Asthma is a major health condition in Iran. This randomized clinical trial was aimed for the comparison of the effects of two exercise protocols (aerobic and aerobic-strength) on the pulmonary indices and quality of life of asthmatic patients.
Methods: The study was conducted in pulmonary ward of Dr Shariati Hospital in Tehran, and Research Center of Exercise Medicine of Tehran in 2009. Fifty six asthmatic patients were selected and after two weeks of education, their spirometric parameters were recorded and the St George's respiratory questionnaire was completed. Then patients were randomly assigned to two groups of A and B. For ten weeks group A did the aerobic-strength exercises and group B did only the aerobic ones at home. At the end, again their spirometric parameters were recorded and the questionnaire was completed. Finally 42 patients completed the study.
Results: After the intervention, FEV1 and FVC but not FEV1/FVC increased in group A. There were no changes in these parameters in group B. In addition, post-intervention FEV1 and FVC were significantly higher in group A than group B. All scores of St George's respiratory questionnaire were significantly improved in both groups but they were not different between them.
Conclusions: Our findings showed that regular aerobic exercises, individually or concomitant with strength exercises, could improve vital signs and quality of life of mild to moderate asthmatic patients. However, only aerobic exercises with strength ones improve spirometric parameters. Therefore, a combination of both aerobic and strength exercises could be considered in treatment protocols of asthmatic patients.

Background: Obesity is a major health problem all around the world. On the other hand, few
people, especially women, are physically active to the levels recommended by Healthy
People 2010 web site managed by
the U.S. Department of Health and Human Services. The
objective of this study was to compare the potential effects of intermittent
and continuous exercise programs combined with concurrent calorie restriction
diets on lipid profile and fasting blood sugar in overweight and obese females.
Methods : Forty-five women with a sedentary life style and a BMI
greater than 25 kg/m2,
were randomly assigned to one of the three groups (15
subjects in each group): a) 40
minutes of medium-intensity intermittent exercise (64-76%
of maximal heart rate), 3
bouts per day for 5 days a week, b) a
single bout of a 40-minute continuous
exercise per day for 5 days a week, C)
the non-exercising control group. A self-monitored
calorie restricted diet was recommended to all participants by a dietitian. The
lipid profile, fasting blood sugar and blood pressure of all participants were
assessed at baseline and 12 weeks after the intervention
period.
Results : After the intervention, there were no significant differences among the groups
in terms of lipid profile [cholesterol (P=0.94),
triglyceride (P=0.62)] fasting blood sugar (P=0.054),
systolic blood pressure (P=0.84) or diastolic
blood pressure (P=0.30).
Conclusion: There
seems to be no significant differences between short term continuous and
intermittent aerobic exercise programs in improving lipid profile, fasting
blood sugar or blood pressure both in overweight and obese women.

Abstract
Background: Studies indicate that obestatin, an anti-hunger peptide, plays an important role in energy balance, GH secretion, and body weight. It has been physiologically shown that obestatin apposes the function of Ghrelin. The purpose of the present study was to investigate the effects of a single session of aerobic exercise in trained women (a 1.5-mile run) on the expression of obestatin gene found in lymphocytes.
Methods: 16 trained female participants (4±1 years of training experience) were voluntarily selected from Khorasan province in Iran and were randomly divided into two groups: the control and aerobic exercise groups. The participants in the aerobic group were asked to run for 1.5 miles with a fixed speed (70 VO2 max) while the controls were passively present in the exercise environment. Following an overnight fast, blood samples (10 ml from the antecubital vein) were collected before and immediately after the exercise from all the participants. Obestatin expression was investigated after separating the lymphocytes by centrifuge and using semi-quantitative RT-PCR.
Results: There was a rise in obestatin gene expression in the case group after one session of aerobic training versus the control group but the changes were not statistically significant.
Conclusion: The results indicated that a single aerobic exercise could not significantly increase the expression of obestatin. Perhaps the type, duration and intensity of the applied protocol in this study did not have a cumulative effect on this gene although these results are in harmony with the results of other studies in this regard.

Abstract
Background: Obesity and sedentary lifestyle are growing problem. The global community's concern is to find the best strategy to obtain a more efficient process of weight reduction, increase physical activity, and minimize weight regain level. The purpose of this study was to evaluate the long-term effects of a short-term intervention on weight changes.
Methods: The present study is a one-year follow-up study of a 12-week intervention during which the 15 individuals in the intermittent group performed 40 minutes exercise in three bouts per day however, the 15 participants of the continuous group did the same but 40 minutes continuously. The 15 participants in the control group had no exercise prescription. After one year, weight changes, body fat percentage, and BMI were re-evaluated in the groups.
Results: After adjusting the baseline weight, patterns of change in the mean weights from the end of the third month to the twelfth month were different across groups (P=0.02). After significant weight loss in the intermittent group, the mean weight in this group increased by 2.32 kilograms during the period, although not statistically significant. No increase was observed in the control group’s mean weight (P=1.00). In the continuous group, the mean weight increased statistically (P=0.048, 3.63 kilograms).
Conclusion: It seems that long-term effects of moderate intensity intermittent aerobic exercise in overweight and obese women on weight control are more efficient than those of continuous exercise. However, for a change in lifestyle and prevention of weight regain, longer follow-ups are required.

Abstract
Background: Probably L-Carnitine can induce increasing of Pyruvate dehydrogenase activity, decreasing of lactic acid production and performance improvements due to the reinforcement of long chain fatty acid oxidation and stabilize of Coenzyme A (CoASH) to free Coenzyme A (COA). Based on this, the aim of this study was to investigate the effect of acute L-Carnitine supplementation on blood lactate, glucose, VO2max and anaerobic power in trained men.
Methods: Sixteen trained men (aged 19-23) volunteers from University of Guilan, facul-ty of Physical Education and Sport Sciences participated as subjects in this investiga-tion. Subjects divided to aerobic (A) and anaerobic (An) group randomly. In a double blind design, subjects participated in two separated tests by one week. Subjects ingested 3 grams of L-Carnitine supplementation or placebo (maltodextrin) 90 minute before aerobic and anaerobic exercise. For aerobic activity used shuttle run 20 meter and for anaerobic activity used RAST test. Blood samples were collected 5 minute prior at rest and 4 minute post tests. Participants were asked in the morning to obtain fasting blood samples and perform tests. A t-test was used to detect differences between supplementa-tion and placebo groups in each exercise.
Results: L-Carnitine group ((A) 141.25±20.62 and (An) 145.38±55.47) significantly had lower lactate concentration than placebo ((A) 151.00±20.85 and (An) 152.50±28.59) after tests (P≤0.05). L-Carnitine group ((A) 136.00±19.74 and (An) 115.50±13.64) had significa-ntly higher blood glucose compared to placebo ((A) 121.62±15.65 and (An) 110.12±12.63) too (P≤0.05). Also, VO2max, mean and maximum anaerobic power in L-Carnitine group were significantly more than ones in placebo (P<0.05).
Conclusion: These findings indicate that acute oral supplementation of L-Carnitine can induce fatigue decreasing and improvement of aerobic and anaerobic performance.

Methods: This investigation is a semi-experimental study that was performed in September 2015 at Urmia University, Iran. The statistical population was all healthy and sedentary postmenopausal women 50 to 65 years old in Urmia city. Twenty sedentary postmenopausal women with an average age 60.12±2.12 yr, weight 72.35±10.50 kg, and body mass index 29.46±3.24 kg/m2 voluntarily and bona fide participated in this study, and then subjects were randomly divided to the Exercise/E (10 women) and Control/C (10 women) groups by random sampling method. E group performed of 12 weeks walking and jogging moderate-intensity aerobic exercise at 65-70% maximal heart rate of training, three sessions per week and per session 50-60 (min), but the C group participated in no intervention. Twenty-four hours before and after the 12-week training program were taken blood samples in order to measure of alkaline phosphatase gene expression and serum markers of bone in the E and C Groups. Evaluation of gene expression and serum markers of bone were measured by real-time reverse transcription PCR (RT-PCR) and Auto-analyzer (Biotechnica, Italy)/ ELISA reader (Awareness Inc., USA) machines, respectively. Data analysis included descriptive and inferential (ANCOVA test) statistics using SPSS version 23 (Chicago, IL, USA) and a significance level of P≥0.05 was considered.
Results: The results showed that alkaline phosphatase gene expression and parathyroid hormone after 12 weeks of moderate-intensity aerobic exercise in between-groups were significantly increased (P=0.027 and P=0.006, respectively), while serum levels of calcium and alkaline phosphatase were not significantly different (P=0.941 and P=0.990, respectively).

Abstract
Background: Type2 diabetes is a metabolic disease that is rapidly increasing in the world. GLUT4 and RBP4 are factors that play a role in glucose uptake. This study aimed to investigate the effect of moderate-intensity continuous training on RBP4 and GLUT4 gene expression of soleus muscle in STZ induced diabetic rats.
Methods: This experimental study was conducted between May and September 2016 at Baqiyatallah University of Medical Sciences. In this study, there were 48 8-week-old male Wistar rats (mean weight 250±20) that were randomly divided into four groups: basic control, 12-week control, diabetes, diabetes and moderate continuous training. Diabetes was induced by injection of streptozotocin solution. The training protocol consisted of continuous aerobic training for 12 weeks, five sessions per week in the form of running on a treadmill. After sampling, real-time PCR expression was used to measure gene expression. Statistical analysis was performed by SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) and graphs were drawn using GraphPad Prism, version 8, (GraphPad Software, USA).
Results: According to the results, there was a significant increase in RBP4 in the diabetic group compared to other groups. compared to the two groups of diabetes and diabetes, along with moderate continuous training, RBP4 gene expression was less expressed in diabetic training. Regarding GLUT4, there was a significant difference between diabetes and diabetes groups with training. Also, the expression of the GLUT4 gene in the diabetic group with training was higher than the other groups. According to this study, it was shown that moderate-intensity continuous training somehow reduces the negative effects of diabetes on metabolism and health by activating various cellular and molecular pathways and mechanisms.
|
Conclusion: the present study showed the effect of moderate-intensity continuous training on the expression of RBP4 and GLUT4 genes in soleus muscle which can be effective in glucose uptake. It was also shown that moderate-intensity continuous training can minimize the complications of diabetes by reducing RBP4 gene expression.
