چکیده
مقدمه: در این مطالعه اثر تعاملی دوازده هفته فعالیت ورزشی هوازی و مصرف مکمل مولتی ویتامین- مینرال بر میزان سرب خون مردان در مواجهه با هوای آلوده شهری مورد بررسی قرار گرفت.
روش کار: در این تحقیق نیمه تجربی، تعداد 46 آزمودنی‌ مرد با میانگین 2.1±25 سال، به صورت داوطلبانه و با رضایت کامل در این مطالعه شرکت و به صورت تصادفی در 4 گروه؛ مکمل و تمرین (11 نفر)- تمرین (11 نفر)– مکمل (12 نفر) و کنترل (12 نفر) قرار گرفتند. فعالیت هوازی با پروتکل تمرینی یکسان و فزاینده برای گروه ترکیبی و تمرین شامل: هفته اول 12 دقیقه دویدن با 60 درصد ضربان قلب ذخیره تا هفته دوازدهم به تدریج به 30 دقیقه دویدن با 85 درصد ضربان قلب ذخیره ای و مصرف مکمل مولتی ویتامین-مینرال به اندازه یک عدد کپسول 500 میلی گرم هر روز برای گروه های ترکیبی و مکمل پژوهش انجام گرفت. متغیر میزان سرب خون یک بار قبل و یک بار بعد از پایان 12 هفته با نمونه گیری خونی سه میلی متر از ورید بازویی با روش طیف سنجی جذب اتمی کوره گرافیتی اندازه گیری شد. از آزمون تحلیل واریانس با اندازه گیری های مکرر برای مقایسه بین گروهی و آزمون تعقیبی LSD برای مقایسه زوج گروه ها استفاده شد. سطح معناداری (0.05>p ) در نظر گرفته شد.
یافته ها: پس از 12 هفته مداخله، کاهش معناداری در میزان غلظت سرب خون در گروه های ترکیبی و مکمل و افزایش معنادار در گروه تمرین در مقایسه با قبل از مطالعه مشاهده شد (0.05>p). نتایج تحلیل واریانس با اندازه گیری تکراری تفاوت معناداری بین گروه ها در میزان غلظت سرب نشان داد، که این تفاوت فقط بین گروه ترکیبی و گروه تمرین معنادار بود.
نتیجه گیری: نتایج پژوهش نشان داد که مصرف مکمل موجب کاهش قابل توجه میزان غلظت سرب هنگام فعالیت ورزشی هوازی در هوای آلوده می شود. بنابراین، پیشنهاد می شود برای کاهش جذب سرب هنگام فعالیت ورزشی هوازی، مواد غذایی حاوی ویتامین ها و املاح مورد نیاز بدن به اندازه مصرف و در صورت کمبود از مکمل های آنتی اکسیدانی استفاده شود.

چکیده English

Introduction: In this study, the interactive effect of 12 weeks of aerobic exercise and the intake of multivitamin-mineral supplementation on blood lead levels in the men exposed to urban air pollution was investigated.
Materials and Methods: In this quasi-experimental study, 46 men with the average age of 25±1.2 year took part voluntarily and with complete satisfaction were randomly assigned to 4 groups: supplement and exercise (N=11), exercise (N=11), supplement (N=12), control (N=12). Aerobic exercise was carried out with the same and increasing practice protocol for the first and second groups (including the first week of 12 minutes running with 60% heart rate up to 12th week, progressively 30 minutes running with 85% heart rate reserve) and with supplementation of multivitamin - minerals (500mg) which were taken as one capsule each day for the first and third groups of the research. The variable including blood lead levels were measured before and after 12 weeks with 3 ml blood sampling from the venous vein by Graphite furnace atomic absorption spectrometry (GFAAS). A repeated measure ANOVA test was used for comparison between groups and the LSD test was used to compare the group pairs. A significant level (P<0.05) was considered.
Results: After 12 weeks of intervention, there was a significant decrease in the concentration of lead in the combined and supplementary groups and a significant increase in the exercise group compared with the pre-study (P<0.05). The results of ANOVA showed a significant difference between the groups in the concentration of lead. This difference was significant between the combined group and the training group, while there was no significant difference between the combined and complementary groups.
Conclusion: The results of this study showed that Consumption of supplementation reduced the concentration of lead when aerobic exercise activity urban polluted air. Therefore, using the same amount of vitamins and necessary minerals is recommended in order to reduce lead absorption during aerobic exercise, and in case of shortage, use antioxidant supplements, such as the multivitamin-mineral supplement.
