The concurrent effect of one bout aerobic exercise and short-term garlic supplementation on the lipids profile in male non-athletes

زمینه و هدف: بیماری های قلبی- عروقی امروزه به عنوان یکی از عوامل تهدید کننده سلامتی انسان ها بخصوص در بیماران کم توان ذهنی محسوب می شوند. این مطالعه با هدف بررسی تأثیر دوازده هفته تمرین هوازی بر نیمرخ لیپیدهای سرمی و توان هوازی دختران کم توان ذهنی غیر ورزشکار طراحی و اجرا شد. روش بررسی: در این مطالعه کارآزمایی بالینی،22 دختر کم توان ذهنی با میانگین سنی 5/0±38/23 سال، قد 6/4±161 سانتیمتر، وزن 73/6±15/61 کیلوگرم، نمایه توده بدن 19/4±68/25 کیلوگرم بر مجذور قد و با بهره هوشی50 تا 75 به صورت نمونه گیری در دسترس انتخاب و به صورت تصادفی در دو گروه تجربی (10 نفر) و شاهد (12 نفر) تقسیم شدند. گروه تجربی در یک دوره تمرینات هوازی به مدت 12 هفته، با شدت 60 تا80 درصد ضربان قلب ذخیره شرکت نمودند؛ ولی گروه شاهد در هیچگونه تمرینی شرکت نکردند. متغیرها در دو گروه، در دو مرحله ی پیش و پس آزمون مورد مقایسه قرار گرفتند. یافته ها: قبل از آزمون بین دو گروه از نظر سن، قد، وزن و شاخص توده بدنی تفاوت معناداری وجود نداشت (05/0P). میانگین نسبت محیط کمر به باسن، درصد چربی بدن، لیپوپروتئین- کلسترول با چگالی بالا بین دو گروه تفاوت معنی دار ی نشان داد (05/0>P). نتیجه گیری: براساس نتایج این مطالعه فعالیت هوازی می تواند متابولیسم لیپوپروتئین ها را تغییر داده و سبب کاهش عوامل خطر ساز بیماری قلبی- عروقی در دختران کم توان ذهنی شود

The Effect of a Six- Month Aerobic Exercise on Levels of GH, IGF-1 and GH/IGF-1 Ratio Serum in Sedentary Middle-aged Women

Introduction: In recent years, a number of researches have been carried out regarding the relationship between atherosclerosis and serum levels of GH and IGF-1 and different results were obtained. This study aimed to determine the effect of a six-month aerobic exercise on levels of GH, IGF-1 and GH/IGF-1 ratio serum in sedentary middle-aged women Methods: Nineteen healthy females, who were selected by convenience sampling method, were divided into two [active (n=11) and non-active (n=8)] groups. The exercise protocol included aerobic exercise training lasted for 6 months and 3 sessions per week. Every session lasted for 60 minutes with intensity of 55-65 percent of heart rate reserve. Blood samples were taken and Serum IGF-1 and GH were measured before and after six months of aerobic training. To make intra and intergroup comparisons as well as to investigate the interactive effect, repeated measure analysis of variance were used. For all statistical comparisons, the level of significance was set at p < 0.05. Results: This study demonstrated that the level of serum IGF-1 in middle-aged women decreased significantly (P=0.016). However, the levels of GH didn't change significantly during this period. Moreover, GH to IGF-1 ratio increased significantly (P=0.007). Conclusion: The study results indicated that six-month aerobic exercise led to a decrease on the levels of IGF-1 and did not make a change in GH serum in sedentary middle-aged women. In other words, doing aerobic exercises reduced IGF-1 levels that have a significant relationship with severity of a coronary disease and thus can prevent the atherosclerosis disease

Effect of 8-week walking program on serum lipoprotein (a) concentration in non-athlete menopausal women

Background and Objective: Lipoprotein (a) [Lp(a)] is a new cardiovascular risk factor and its concentration increase cardiovascular diseases, while physical activity decrease cardiovascular diseases. This study intend to investigate the effect of eight week walking program on lipoprotein (a) concentration in non-athlete iranian menopausal  women. Materials and Methods: Twenty two healthy menopause women of 47-55 year of age any specific disorder were enrolled in this study. The subjects randomly divided into experimental and control groups. Anthropometric characteristics including height ,weight, body mass index (BMI), body fat percent and Waist-to-Hip ratio (WHR) and serum lipoprotein on fasting were measured pre and post-walking program. The data were compared using independent t-test, U mann witny and pearson correlation caefficeint was used for assessement of relation between lipoprotein (a) with anthropometric indexes. Results: According to these results, there was a significant reduction of serum lipoprotein (a) (pre test12.5±4/1 post test 10.5±3md), WHR, BMI and body fat percent prior and after the training in experimental group (P<0.05) while non significant changes was observed in control group. Also, there was non significant relationship between lipoprotein (a) with Anthropometric indexes. Conclusion: This study revealed that 8-week walking program had useful effects on menopausal women’ serum lipoprotein (a) concentration, WHR, BMI and body fat percent

Effect of one session of aerobic exercise associated with abdominal laser therapy in lipolytic activity, lipid profile, and inflammatory markers

Increased abdominal fat and sedentary lifestyles contribute to cardiovascular disease risk. The combination of exercise and low‐level laser therapy (LLLT) appears to be an innovative method to increase the lipolytic rate of abdominal adipocytes, in order to reduce abdominal fat.info:eu-repo/semantics/publishedVersio
