تاثير تمرين هوازي با شدت بالا در شرايط ايزوانرژيك و مصرف آرژنين بر مقادير سرمي PYY3-36 و شاخص هاي آنتروپومتريك پسران چاق

Effect of HIT and Supplementation of Arginine under Isoenergetic Conditions on PYY3-36 Signal and Anthropometric Indices in obese boys

سابقه و هدف. انتخاب مناسب تمرين بدني و ملاحظات تغذيه اي، عاملي مهم در تغيير شيوه زندگي نوجوانان چاق و شاخصي موثر در كنترل و درمان چاقي محسوب مي شود. هدف ما تعيين اثر هشت هفته تمرينHIT در شرايط ايزوانرژيك و مصرف آرژنين بر مقادير سرمي PYY3-36 و شاخص هاي آنتروپومتريك پسران چاق بود. مواد و روش ها. در شرايط ايزوانرژيك 20 نوجوان چاق به صورت تصادفي به دو گروه 1) تمرينHIT و دارونما (10 نفر) و 2) تمرينHIT به همراه مكمل ال آرژنين (10 نفر) تقسيم شدند. قبل از ورود به پروتكل تمرين و 48 ساعت پس از آخرين جلسه تمرين، شاخص هاي آنتروپومتريك و مقادير هورموني PYY3-36 در خون اندازه گيري شد. براي بررسي تفاوت هاي درون و بين گروهي به ترتيب از تي استيودنت وابسته و مستقل استفاده شد. يافته ها. نتايج نشان داد كه تغييرات كاهش وزن درون و بين گروهي معنادار است(0/05≥p). كاهش شاخص توده بدن در هر دو گروه معنادار (0/05≥p) بود؛ اما تغييرات بين گروهي معنادار نبود(0/05

Background&Purpose.physical training appropriate selection and nutritional considerations is an important factor in changing the lifestyle of obese Adolescent and Effective Index in control and treatment of obesity.The purpose of this study was to determine the effect of eight weeks of HIT and supplementation of arginine under isoenergetic conditions on PYY3-36 signal and anthropometric indices in obese boys. Methodology. In isoenergetic conditions, 20 obese adolescents were randomly divided into two groups including: 1) HIT and placebo (C, n=10) and HIT with supplementation of arginine (T, n=10). Before Intervention exercise Protocol and 48 hours after the last exercise session, hormonal levels of PYY3-36 in blood and Anthropometric Indices were measured. For Investigation the differences between intra-and intergroup, Independent and independent Student was used. Results.The results showed that intra-and intergroup weight loss was significant (p≤0.05). The decrease in body mass index in both groups was significant (p≤0.05), but the intra group changes were not significant(P ≥0.05). Body fat percentage changes were not significant in both groups (P ≥0.05). The results showed that there was no significant difference between PYY3-36 peptide compared to baseline levels among and between in C and T groups(P ≥0.05). Conclusion: Despite some contradictions, however, arginine supplementation along with HIT seems to be an effective approach in weight management for obse boys, Although, determining the mechanism and nature of the effect of these exercises on PYY3-36 requires further studies.
