چکیده

زمینه و هدف: در مورد مداخله تمرین مقاومتی و ترکیبی بر پاسخ بیومکانیکی استخوان تحت شرایط پوکی استخوان، اطلاعات کمی در دست است؛ از این رو در مطالعه حاضر، اثر تمرین ترکیبی و مقاومتی بر نشانگرهای تشکیل استخوان و استحکام مکانیکی استخوان ران رت های نر استئوپروتیک مورد بررسی و مقایسه قرار می گیرد. روش تحقیق: از بین 40 رت نر ویستار، 8 رت به عنوان گروه سالم جدا شدند، سپس پوکی استخوان با تزریق صفاقی محلول20% اتانول طی 3 هفته در سایر رت ها القاء گردید. رت های استئوپروتیک به 4 گروه پایه، مقاومتی، ترکیبی و کنترل تقسیم شدند. تمرین مقاومتی شامل 8 نوبت صعود از نردبان عمودی همراه حمل وزنه بود. گروه ترکیبی هر دو برنامه تمرین مقاومتی و استقامتی (60 دقیقه در روز با سرعت 12 متر در دقیقه) را انجام دادند. پس از تکمیل 12 هفته تمرین با تکرار 5 روز در هفته، نمونه های خونی جمع آوری و غلظت استئوکلسین و آلکالین فسفاتاز ویژه استخوان با روش الایزا اندازه گیری شدند. استخوان ران چپ خارج شده نیز به وسیله تست خمشی سه نقطه ای، برای به دست آوردن حداکثر نیرو و سفتی مورد آزمایش قرار گرفت. داده ها با آزمون تحلیل واریانس یک سویه و آزمون تعقیبی توکی در سطح معنی داری 05/0، مورد تجزیه و تحلیل آماری قرار گرفتند. یافته ها: دو گروه مقاومتی و ترکیبی، افزایش معنی داری در تمامی شاخص های اندازه گیری شده نشان دادند (05/0>p). در مقایسه با تمرین مقاومتی، تمرین ترکیبی بر آلکالین فسفاتاز سرم (04/0=p) و استحکام مکانیکی استخوان (0001/0=p)، تاثیر معنی دارتری داشت. نتیجه گیری: احتمالاً تمرین ترکیبی در مقایسه با تمرین مقاومتی، حمایت بیشتری در برابر پوکی استخوان ایجاد می کند.

چکیده [English]

Background and Aim: There is a little information available regarding the effect of resistance and combined training on biomechanical response of bone in osteoporosis condition. This study evaluated the effect of combined training compared to resistance training on bone formation markers and femoral mechanical strength of steoporotic male Rats. Materials and Methods: Among forty male Wistar rats, 8 rats were selected as healthy group, then osteoporosis were induced by intraperitoneal injection of 20% alcohol during 3 weeks for other rats. Osteoporotic rats were divided into 4 groups as: baseline, resistance, combined and control. The resistance training protocol consisted of 8 series of climbing activity on the vertical ladder with weights tied to animal tail. Combined group completed the both of resistance and endurance protocol (60 min/day, 12 m/min speed). After completing 12 weeks of exercise trainings (5 days a week), the blood samples were collected and serum levels of osteocalcin and bone specific alkaline phosphatase was measured by ELISA method. Execised left femurs were examined by three point bending test to obtain the maximum force and stiffness. The data were analyzed by one way-ANOVA and Tukey post hoc tests. A p-value (0.05) was set for data statistical analysis. Results: Two groups of the combined and resistance training showed a significantly increased on all measured parameters versus to control group (p<0.05). The effect of combined training on serum of bone specific alkaline phosphatase (p=0.04) and bone mechanical strength (P=0.0001) was more significant than resistance training. Conclusion: Perhaps the combined training provides more protection against of osteoporosis compared to resistance training.
