چکیده

زمینه و هدف امروزه سبک زندگی کم‌تحرک با شیوع بیماری‌های مختلف و اختلالات متابولیکی همراه است. شاخص آتروژنیک پلاسما (AIP) می‌تواند به عنوان یکی از معیارهای پیش‌بینی‌کننده مهم بیماری‌های کرونری قلب در نظر گرفته شود. هدف از این تحقیق، بررسی تأثیر هشت هفته تمرین هوازی با شدت متوسط بر شاخص‌های تن‌سنجی، آتروژنیک پلاسما و برخی عوامل خطرزای قلبی عروقی در مردان غیرفعال بود. 
مواد و روش‌ها در این تحقیق نیمه‌تجربی40 کارمند غیرفعال با میانگین±انحراف‌معیار سن 8/97±36/17 سال و شاخص توده بدن 4/12±26/60 کیلوگرم بر متر مربع به صورت داوطلبانه و پس از اخذ رضایت‌نامه آگاهانه به مدت هشت هفته (هر هفته سه جلسه و به مدت 45 تا 60 دقیقه) در فعالیت دو با شدت 70 درصد ضربان قلب بیشینه شرکت کردند. نمونه‌های خونی قبل و بعد از تمرین جهت اندازه‌گیری متغیرهای سرمی گرفته شد. داده‌ها به وسیله آزمون آماری تی زوجی در سطح 0/05>P تحلیل شدند. 
یافته‌ها یافته‌ها نشان داد پس از هشت هفته فعالیت ورزشی، درصد چربی بدن (0/04=P)، کلسترول (0/001=P)، نسبت کلسترول به لیپوپروتئین پرچگال (0/001=P)، نسبت لیپوپروتئین کم‌چگال به لیپوپروتئین پرچگال (0/03=P)، نسبت تری‌گلیسرید به لیپوپروتئین پرچگال (0/01=P) و آپولیپوپروتئین B (0/001=P) کاهش معنی‌داری یافتند. همچنین مقادیر حداکثر اکسیژن مصرفی (0/010=P) و لیپوپروتئین پرچگال (0/011=P) پس از هشت هفته شرکت در فعالیت هوازی افزایش معنی‌داری پیدا کرد.
نتیجه‌گیری به نظر می‌رسد افزایش در سطوح فعالیت بدنی در کاهش خطر ابتلا به بیماری‌های قلبی عروقی مؤثر باشد. همچنین می‌توان بر فعالیت بدنی به عنوان یک اقدام حمایتی برای برخوردار بودن از سبک زندگی سالم‌تر در جامعه به‌ویژه در میان کارمندان و افراد غیرفعال تأکید کرد.

چکیده [English]

Background and Aims: The sedentary lifestyle is related to the incidence of various diseases and metabolic disorders. Atherogenic Index of Plasma (AIP) can be considered as an appropriate criterion predicting coronary heart disease. This study aimed to investigate the Effect of 8-week aerobic training on anthropometric Indices, the Atherogenic Index of Plasma, and some cardiovascular risk factors in inactive men.
Methods: In the current quasi-experimental study, 40 inactive employees with a Mean±SD age of 36.17±8.97 years and body mass index of 26.60±4.12 kg/m2 after obtaining testimonial voluntarily performed aerobic exercise training for 8 weeks (each session 45 to 60 minutes) with 70 percent of maximal heart rate. Blood samples were taken before and after exercise to measure serum variables. Data were analyzed by paired t-test at the significant level of P<0.05.
Results: Statistical analysis showed that after 8 weeks of aerobic exercise, Body fat percentage (P=0.04), cholesterol (P=0.001), LDL/HDL ratio (P=0.03), TG/HDL ratio (P=0.01), TC/HDL ratio (P=0.001), and apo-B (P=0.01) decreased significantly. Also, VO2max (P=0.011) and HDL (P=0.010) increased dramatically after 8 weeks of participation in aerobic activity. 
Conclusion: According to the results, an increase in physical activity can probably reduce the risk of cardiovascular disease. Also, physical activity with lowering the risk factors of developing CVD events and significant prevention of its progression, the beneficial properties of physical activity are underscored, and promoting its effectiveness as support for healthier lifestyles in the community and particularly among inactive men is emphasized.
