چکیده
زمینه و هدف: هدف از پژوهش حاضر بررسی تاثیر چهار هفته تمرین متناوب هوازی شدید ویژه فوتبال بر شاخص های عملکردی هوازی بازیکنان فوتبال می باشد. روش تحقیق: به این منظور18 بازیکن فوتبال شرکت کننده در لیگ آزادگان ایران با میانگین سنی 24 / 2± 88 / 21 سال، قد 174/22±5/32سانتی متر، وزن± 5/7 67/77 کیلوگرم و درصد چربی 12/38+ 3/29، در غالب دو گروه تمرین ) 12 نفر( و کنترل ) 6 نفر( برای شرکت در این پژوهش داوطلب شدند. یک برنامه چهار هفته ای تمرین متناوب هوازی شدید )هاف(، سه جلسه در هفته، شامل چهار دوره حرکت با توپ در یک مسیر ویژه از پیش طراحی شده، اجرا گردید. دوره های کاری فعالیت به صورت چهار دوره چهار دقیقه ای با شدت 90 - 95 درصد حداکثر ضربان قلب بود که با سه دقیقه استراحت فعال، و با 70 درصد حداکثر ضربان قلب، اجرا شد. داده ها با استفاده از آزمون های آماری tمستقل و زوجی و آنوا با اندازه گیری مکرر تجزیه و تحلیل شدند. یافته ها:نتایج نشان داد که پس از چهار هفته تمرین، VO2max، و زمان واماندگی بازیکنان اندکی افزایش یافت، اما سطوح هماتوکریت و هموگلوبین در بین دو گروه تمرینی و کنترل تغییر معناداری نکرد. با این حال، کاهش معناداری در نشانگرهای آسیب عضلانی خون پس از تمرین مشاهده شد. نتیجه گیری: بر اساس نتایج تحقیق می توان اظهار داشت که چهار هفته تمرین هاف شاخص های آسیب عضلانی بازیکنان فوتبال را به طور معنادار متاثر ساخت.

چکیده [English]
Background and Aim: The aim of this study was to assess four weeks of high intensity aerobic interval training on aerobic performance in soccer players. Materials and Methods: 18 soccer players (weight: 67.77±5.7 kg, height: 174.22±5.33 cm, age: 21.88±2.24 years, percent body fat: 12.38±3.29 percent) were experienced in Azadegan competitions randomized and divided into two groups (training: 12 players, control: 6 players). Four weeks of high intensity aerobic interval training was performed three times a week at the end of the soccer training sessions. Training intervention consisted of interval training, comprising four bouts of four minutes work periods dribbling a soccer ball. Working intensity was at 90–95% of each player’s HRmax, with work periods separated by 3 min of jogging at 70% of HRmax. The values obtained before and after the training period were compared using Student’s paired and un-paired t –test and ANOVA Repeated Measure test. Results: The results showed that a 4 week training period caused a little increases in the VO2max and Tmax, but hematocrit and hemoglobin did not changed significantly. However, creatin phosphokinase and lactate dehydrogenase decreased significantly after training protocol. Conclusion: It is concluded that four weeks of high intensity aerobic interval training significantly affect muscular damage characteristics in soccer players.
