چکیده

اهداف: فعالیت شدید و بلند مدت منجر به آسیب و پاسخ های دستگاه ایمنی و التهاب می شود، بدین دلیل وجود یک واسطه ضد التهابی طبیعی مانند چای سبز مورد توجه قرار می گیرد. پژوهش حاضر به بررسی تاثیر مصرف چای سبز و انجام تمرینات هوازی شدید بر ترکیب بدن، میزان آنزیم کراتین فسفو کیناز و لاکتات دهیدروژناز در مردان غیر فعال می پردازد.
مواد و روشها: 38 مرد جوان غیر فعال با میانگین سن 63/1±87/19 سال در این پژوهش یک سوکور شرکت کرده و بصورت تصادفی به چهار گروه چای سبز -تمرین هوازی، تمرین هوازی ، چای سبز و کنترل تقسیم شدند. آزمودنی ها روزانه 3 میلی گرم چای سبز یا دارونما را همراه سه وعده غذایی مصرف کرده و علاوه بر آن گروه های چای سبز- تمرین هوازی و تمرین هوازی ، سه جلسه در هفته به مدت یک ماه به تمرین هوازی با شدت 55 تا 85 درصد حداکثر ضربان قلب بیشینه پرداختند. نمونه های خونی قبل و پس از چهار هفته و 24 ساعت پس از آزمون اِل اِستاد از شرکت کنندگان گرفته و شاخص های کراتین فسفوکیناز و لاکتات دهیدروژناز اندازه گیری شد. نتایج با استفاده از آزمون t وابسته و آزمون کواریانس تجزیه و تحلیل شد.
یافته ها : نتایج نشان داد که درصد چربی در گروه چای سبز- تمرین هوازی همراه با کاهش معنی دار بود (001/0>p) اما در بقیه متغیرها معنی داری مشاهده نشد.
نتیجه گیری: به نظرمی رسد که مصرف چای سبز به همراه تمرین هوازی در کوتاه مدت می تواند اثرات مفیدی بر درصد چربی زیر جلد داشته باشد.

چکیده [English]

Purpose: Intensive, long-term activity can damage the immunity system and cause inflammation. So, a natural anti-inflammatory intermediate like green tea has attracted the interests. The objective of the present study was to examine the impact of green tea consumption and intensive aerobic exercise training on body composition, creatine phosphokinase and lactate dehydrogenase parameters in sedentary young men.
Materials and methods: Thirty-eight sedentary young men (age: 19.87±1.63 years) were participated in study and were randomly divided into four groups: green tea + aerobic training, aerobic training, green tea, and control. The subjects took three mg green tea or placebo a day with their meals. Also, green tea + aerobic training and aerobic training groups had aerobic training with 55-85% of maximum heart beat rate three sessions a week for one month. Blood samples were taken before and after four weeks and 24 hours after El-Estado test and their creatine phosphokinase and lactate dehydrogenase were measured. Data were analyzed with t-paired test and covariance test.
Results: It was revealed that fat percentage was significantly lower in green tea group (p < 0.001) but, no significance was observed in other variables.
Conclusion: It seems that green tea consumption with regular, short aerobic activities can favorably affect subcutaneous fat percentage.
