چکیده مقاله :
زمینه و هدف: میدانهـاي الکترومغناطیسـی بر سیستم قلبی و کبدی انسان تاثیر مخربی دارد. با توجه به نقش فعالیت ورزشی بر سلامت انسان، مطالعه حاضر با هدف بررسی 8 هفته تمرین هوازی بر آنزیمهای کبدی، وزن قلب، وزن بدن و نسبت وزن قلب به وزن بدن موشهای صحرایی در معرض امواج الکترومغناطیسی صورت گرفت.
مواد و روش ها: در این مطالعه تجربی تعداد 32 سر موش صحرایی به طور تصادفی به چهارگروه (1) کنترل بدون هیچ گونه مداخله، (2) کنترل تحت اشعه الکترومغناطیس، (3) گروه تمرین هوازی تحت تاثیر اشعه الکترومغناطیس و (4) تمرین هوازی بدون اشعه الکترومغناطیس و هر گروه 8 سر موش تقسیم شدند. گروه های 2 و 3 هشت هفته به مدت 1 ساعت در روز در معرض اشعه الکترومغناطیس قرار گرفتند. نمونههای گروههای 3 و 4 سه جلسه در هفته به مدت 8 هفته بر روی نوار گردان دویدند. سطوح سرمی آلانین آمینوترانسفراز، آسپارتات آمینوترانسفراز اندازهگیری و گروهها با هم مقایسه شدند.
نتایج: قرار گرفتن در معرض اشعه الکترومغناطیس اثر معنی داری بر سطوح آلانین آمینوترانسفراز و آسپارتات آمینوترانسفراز نداشت اما منجر به افزایش سطوح وزن، افزایش وزن قلب و افزایش نسبت وزن قلب به وزن بدن موش های صحرایی گردید (05/0>P). تمرینات هوازی منجر به کاهش وزن، وزن قلب و نسبت وزن قلب به وزن بدن موشهای صحرایی تحت اشعه الکترومغناطیس گردید (05/0>P). تمرین هوازی همچنین، موجب افزایش سطوح آلانین آمینوترانسفراز و آسپارتات آمینوترانسفراز موشهای صحرایی تحت اشعه گردید (05/0>P). سطوح آسپارتات آمینوترانسفراز در گروه تمرین هوازی به طور معنی داری بالاتر از گروه تمرین هوازی تحت اشعه بود (05/0>P).
نتیجهگیری: به نظر می رسد اشعه الکترومغناطیس اثری بر آنزیمهای کبدی ندارد، درحالیکه موجب افزایش سطوح وزن، وزن قلب و نسبت وزن قلب به وزن بدن موش های صحرایی میگردد. انجام تمرینات هوازی وزن، وزن قلب و نسبت وزن قلب به وزن بدن موشهای صحرایی تحت اشعه الکترومغناطیس را کاهش میدهد و اثر مثبت بر آنزیمهای کبدی دارد.
Background and aim: Electromagnetic fields have a detrimental effect on the human heart and liver system. Considering the impact of physical activity on human health, the present study aims to investigate the effects of 8 weeks of aerobic training on liver enzymes, heart weight, body weight, and the heart weight-to-body weight ratio in rats exposed to electromagnetic waves.
Materials and Methods: In this experimental study, 32 rats were randomly divided into four groups: (1) a control group without any intervention, (2) a control group exposed to wireless electromagnetic radiation, (3) an aerobic exercise group exposed to wireless electromagnetic radiation, and (4) an aerobic exercise group without electromagnetic radiation (each group has 8 rats). Groups 2 and 3 were exposed to electromagnetic radiation for 1 hour a day over eight weeks. The samples from groups 3 and 4 underwent treadmill exercise three times a week for the same duration. Serum levels of were measured, and the groups were compared. alanine aminotransferase and aspartate aminotransferase
Results: Exposure to wireless radiation had no significant effect on alanine aminotransferase and aspartate aminotransferase levels, but it resulted in increased weight, heart weight, and the heart weight-to-body weight ratio in rats (P<0.05). Aerobic exercises led to decreased weight, heart weight, and the heart weight-to-body weight ratio in rats exposed to wireless radiation (P<0.05). Additionally, aerobic exercise increased alanine aminotransferase and aspartate aminotransferase levels in rats under wireless radiation (P<0.05). Notably, aspartate aminotransferase levels in the aerobic exercise group were significantly higher than those in the aerobic exercise group exposed to wireless radiation (P<0.05).
Conclusion: It seems that electromagnetic radiation has no effect on liver enzymes, while it increases the levels of weight, heart weight and the ratio of heart weight to body weight in rats. Performing aerobic exercises reduces the weight, heart weight and ratio of heart weight to body weight of rats exposed to wireless radiation and has a positive effect on liver enzymes.
