The adipocyte‐derived hormones leptin is known to increase in obesity and related disease. Thirty two non‐trained males (39±4.32 years, 176.5 – 6.5 ± 6.42 cm, and 31 ± 3.14 body fat %) were matched according to physical fitness enrolled in this study and divided to exercise and control group by accidentally. The participants of exercise group were completed an aerobic exercise program for 3 months (3 days/weekly) and control group were barred of exercise in this period. Anthropometrical measurements and fasting blood samples were obtained before and after interventions in two groups. Blood samples were collected in order to measuring serum leptin, triglyceride (TG), high density lipoprotein cholesterol (HDL), and Low density lipoprotein cholesterol (LDL). Pre‐ and post exercise independent variables were compared using a paired‐samples t‐test. Compared to pre‐training, the leptin levels decreased significantly (P<0.01) after aerobic exercise program in exercise group but not in the control subjects. Triglyceride concentration was decreased with exercise training whereas concentrations of LDL cholesterol did not change in exercise group (p≥0.05). Exercise training resulted in significant decrease in anthropometrical indexes (p Ë‚ 0.05) and a borderline significant increase in HDL (p=0.052). TG/HDL ratio were significantly decreased in exercise group by exercise training (p=0.028). All variable in control group remained no change in control group (p ≥ 0.05). These data suggest, despite lack significant changes in some lipid profile markers, aerobic exercise program can be improve systemic inflammation and TG/HDL ratio as a cardiovascular risk factor in obese subjects.

Abstract Background: Omentin-1 is a recently circulating adipokine that plays a crucial role in modulating insulin resistance and diabetes. We investigated the effect of eight weeks aerobic exercise training on serum omentin-1, insulin resistance and lipid profile in the smoker and non-smokers with normal-weight. Methods: Nineteen healthy men and twenty smoker men were randomly assigned into healthy control group (C), healthy exercise group (E), control smoker group (CS) and exercise smoker group (ES). Exercise groups participated in an 8-weeks aerobic exercise training program (three times a week, 45 min per session at 65%-80% of maximum heart rate). Serum omentin-1 and insulin values were determined by ELISA and HOMA-IR, glucose and lipid profile were measured at pre and post of the intervention. Paired Sample t-test, one-way analysis of variance (One-way ANOVA) and post-hoc Tukey test were applied to analyze the data (p<0.05).Results: Aerobic exercise improved both serum omentin-1 and high lipoprotein cholesterol (HDL-C) in the exercise groups (p<0.05). Also, Exercise training reduced insulin, blood sugar, HOMA-IR, total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels (p<0.05). Omentin-1 were significantly associated with insulin (r=-0.40, P=0.01), HOMA-IR (r=-0.38, P=0.04), TG (r=-0.40, P=0.01), TC (r=-0.49, P=0.02), LDL-C (r=-0.70, P=0.02) and HDL-C (r=0.55, P=0.03).Conclusion: The findings suggest that aerobic exercise-induced changes in omentin-1 in exercise trained smokers may be associated with the beneficial effects of exercise on reduced insulin and lipid profile.

Introduction: Obesity is a major risk factor for inflammation and cardiovascular diseases. We tried to assess whether 12 weeks of aerobic exercises affect serum resistin level and lipid profile in overweight females or not. Methods: For this purpose, 32 non-trained adult females with the mean age of 38 ± 7 years old and body mass index (BMI) of 32 ± 3 kg/m2 were randomly assigned to aerobic exercise (n=16) and control (n=16) groups. Twelve weeks of aerobic exercise program including 3 sessions weekly at 60-75% of maximum heart rate was considered. Fasting serum resistin level, lipid profile (total cholesterol [TC], low-density lipoprotein [LDL] and high-density lipoprotein [HDL] cholesterol, and triglyceride [TG]), and anthropometric indexes were measured and compared between the two groups before and after training. Results: Serum resistin, lipid profile markers, and anthropometrical indexes were not significantly different at baseline between the two groups (P>0.05). TG, TC, LDL, and serum resistin did not change significantly after the intervention in the exercise group (P>0.05). However, a significant increase in HDL (exercise: 46.3 ± 9.6 vs. 51.4 ± 8.5, P=0.011; control: 45.8 ± 7.9 vs. 46.8 ± 6.9 P=0.326) and a significant decrease in LDL/HDL ratio (exercise: 2.94 ± 0.12 vs. 2.47 ± 0.19, P=0.019; control: 3.14 ± 0.23 vs. 3.18 ± 0.63, P=0.265) were observed after the intervention. Other variables in the control group remained unchanged. Conclusion: Aerobic exercises had no impacts on the inflammatory profile but could improve lipid profile with an emphasis on HDL in adult obese women.

Background: Limited energy intake with physical activity is effective to reduce health problems associated with obesity. It has been shown that PYY3-36 level increased after intense exercise. This study investigated effect of exercise therapy on appetite suppression and weight loss among obese and/or overweight women. Methods: There was a quasi-experimental with a pretest-posttest design, two groups (control-exercise) study. Study population was overweight or obese women with 20-34 years old and body mass index 27-34 kg/m2. 13 women were randomly assigned in 2 groups (exercise group with 8 weeks of aerobic exercise training (n=7) and control group (n=6)). Weight, waist circumference, hip circumference, lipid profile, cortisol and PYY3-36 were measured at baseline and end of the study. Results: In baseline of study, there was no significant difference across the groups in factors mean (P>0.05).In control group, after 8 weeks, there was no significant difference in variables.(P>0.05) However, In exercise group significant decrease was observed in BMI, WHR, PYY3-36, TG, CHOLESTROL(TC) and LDL, compared to control group (P<0.05). Conclusion: Aerobic exercise within the 80% of heart rate reserve is beneficial in lipid profile, appetite management and modified anthropometric factors. These studies demonstrate that a cortisol change is not along with PYY3-36 changes. We suggest the longer exercise training for this purpose.

In addition to a variety of lipids, 2 products of the arachidonic acid cascade, prostacyclin and thromboxane, are involved in the pathogenesis of atherosclerosis as a result of their effects on platelet function and on the vascular endothelium. The aim of the present investigation was to ascertain if a sub-maximal 8 week endurance training period followed by a 4 week detraining period would have any effects on high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglycerides (TG), 2,3-dinor-6-keto-prostaglandin F1α(2,3-dinor-6-keto-PGF1α), the urinary metabolite of prostacyclin, 2,3-dinor-thromboxane B2(2,3-dinor-TXB2), the urinary metabolite of thromboxane, and the ratios of TC to HDL-C and of 2,3 dinor-6-keto-PGF1αto 2,3-dinor-TXB2. Thirty-eight boys aged 10–14 were randomly divided into exercise (n = 21) and control (n = 17) groups. The exercise group trained on a bicycle ergometer 4 times/week, 1 h/session, at 80% of their physical working capacity at a heart rate of 170 beats/min (PWC170), for 8 weeks. The control group did not participate in any specific physical exercise program. The results showed that relative to the control group, the exercise group had a significant increase in HDL-C and 2,3-dinor-6-keto-PGF1αconcentrations at the end of the 4th (p < 0.05 and p < 0.001, respectively) and the 8th week (p < 0.01 and p < 0.001) of training, respectively; a significant increase in the 2,3 dinor-6-keto-PGF1α– 2,3-dinor-TXB2ratio (p < 0.05 and p < 0.01 at the same intervals); a significant decrease in TG at the end of the 8th week of training (p < 0.05); and a significant decrease in the TC–HDL-C ratio at the end of the 4th (p < 0.05) and 8th weeks of training (p < 0.001).

The metabolic fitness (MF) is a component of athletes’ physical conditioning. This study aims to investigate the effects of quercetin supplementation on Turkish Junior athletes’ lipid and protein metabolism relating to MF after one month classic boxing training. Totally 20 voluntary junior male athletes were separated into two equal groups as the experimental group (EG) and control group (CG). The participants were supplemented with 500 mg quercetin fifteen minutes before each workout in one month boxing training program. Blood samples during pre and post training were taken from athletes in order to determine metabolic fitness related parameters. Lipid profile contains low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), trigliserid (TG), total cholesterol (TC) variables while protein metabolism includes the albumin, total protein, direct bilirubin and total bilirubin parameters. The Mann Whitney U analyzes were used for comparison of the means between experimental and control groups during pre and posttest and between pre and post test results in experimental and control groups. This study showed that EG had a similar physical characteristic with CG. There were significant decrease in TC and LDL-C and an increase in HDL-C in EG while there was only significant increase in HDL-C of in controls. A significant difference of HDL-C was observed between EG and CG during pretest. In other side, TC and LDL-C and HDL-C were significantly differentiated between EG and CG during posttest. Conclusion: it can be concluded that quercetin plays an important role on lipid metabolism not protein.

Objectives: To study the effect of four weeks of aerobic exercise training, on sleep quality and quality of life parameters like anxiety, depression and physical functioning in Post Myocardial Infarction (MI) patients. Methods: ST elevated MI patients (n=21, <65years age) were voluntarily divided into 2 groups, control group (n=11) and exercising group (n=10). The patients in experimental group followed an exercise program of 3 sessions per week for 4 weeks. The subjective quality of life, anxiety and depression levels were assessed by the SF 36 questionnaire and Hospital Anxiety & Depression Scale (HAD scale) and the sleep quality was assessed using Pittsburgh Sleep Quality Index (PSQI). Poor sleep quality and short sleep duration was defined as PSQI > 5 and total sleep time <6hrs. respectively. After 4 weeks of the program the questionnaires were repeated for all 21 patients. Wilcoxon rank order test and Student T test were used. P<0.05 was considered statistically significant Results: Intergroup analysis showed statically significant reduction in anxiety score (9vs0.5) and depression score (3vs0) in exercise group as compared to control group respectively. As compared to control group, exercise group also showed statistically significant improvement in the quality of life parameter score [physical functioning (750vs1000), role functioning physical (0vs400) & emotional (0vs300), energy level (215vs400), emotional well-being (400vs500), social functioning (120vs200), general health (230vs462.5) & health changes (50vs100)]. Intra group analysis also showed significant changes only in exercise group. After 4 weeks of exercise training, PSQI score improved in the experimental group from 9.5±4.11 to 1.13±0.35 (p=0.00029) indicating better sleep quality and duration. While it remained comparable to the baseline values in the control group i.e. from 9.9±4.70 to 10.33±3.87 (p value= 0.514). Conclusion: Four weeks of exercise program improves the quality & duration of sleep and quality of life in MI patients after 2 weeks of index event.
