چکیده
واسپین بهعنوان یک آدیپوسایتوکاین، دارای تأثیرات حساسیت انسولینی است. با وجود تأثیرات ورزش بر هموستاز انرژی و تغییرات بافت چربی، مطالعات کمی به بررسی تأثیر ورزش بر میزان واسپین پرداختهاند. مطالعۀ حاضر به بررسی تأثیر تمرین مقاومتی بر سطح سرمی واسپین و CRP پرداخته است. بدین منظور 20 مرد چاق کمتحرک با میانگین و انحراف استاندارد سن، وزن و شاخص تودۀ بدنی (1/2 ± 1/50 سال، 8/5 ± 6/92 کیلوگرم، 4/1 ± 3/30 کیلوگرم بر متر مربع) انتخاب و بهصورت تصادفی به دو گروه فعالیت ورزشی (10نفر) و کنترل (10نفر) تقسیم شدند. برنامۀ تمرینی گروه تجربی به مدت 12 هفته و هر هفته 3 جلسه تمرین بود. مرحلۀ اول خونگیری پس از 12 ساعت ناشتایی و مرحلۀ دوم خونگیری 48 ساعت پس از خاتمۀ تمرینات در شرایط تجربی اجرا شد. سطح سرمی واسپین و CRP در گروه تجربی پس از 12 هفته تمرین بهترتیب 8/8 و 5/2 درصد کاهش یافت (05/0>P). وزن، شاخص تودۀ بدن، درصد چربی و اندازۀ دور کمر بهترتیب 7/0-، 8/0-، 08/2 - و 01/1- درصد و گلوکز خون و مقاومت انسولینی بهترتیب 4/4 و 01/5 درصد کاهش معناداری داشت (05/0>P). بین تغییرات واسپین با شاخصهای آنتروپومتریکی، مقاومت انسولینی و CRP رابطۀ معناداری مشاهده نشد.

چکیده [English]
Vaspin as a new adipocytokine improves insulin sensitivity. Despite the effects of exercise training on energy homeostasis and changes in fat tissue, few studies have investigated the effect of exercise training on vaspin. This study investigated the effect of resistance training on serum levels of vaspin and CRP. 20 sedentary obese men (mean + SD age: 50.1 + 2.1 years, weight: 92.6 + 5.8 kg, BMI: 30.3 + 1.4 kg/m2) were selected and randomly divided into two groups: exercise (n=10) and control (n=10). Training program of the experimental group consisted of 3 sessions a week for 12 weeks. Blood samples were gathered after 12 hours of fasting and then 48 hours after the last training session in the experimental condition. Serum levels of vaspin and CRP decreased (8.8%, 2.5% respectively) in the experimental group after 12 weeks (P˂0.05). Weight, BMI, BF% and waist circumference significantly decreased (-0.7%, -0.8%, -2.08% and -1.01% respectively). Blood glucose and insulin resistance significantly decreased (respectively 4.4%, 5.01%) (P˂0.05). There was no significant relationship between changes of vaspin and anthropometric indexes, insulin resistance and CRP.
