چکیده

هدف این پژوهش بررسی تأثیر شش هفته تمرینات تناوبی مبتنی بر نقطۀ شکست ضربان قلب (HRDP) براساس مدل D-Max بر لاکتات خون، عملکرد و مدت زمان رسیدن به خستگی بازیکنان جوان فوتبال بود. 20 بازیکن فوتبال برای شرکت در این پژوهش داوطلب شدند و به شکل تصادفی به دو گروه تمرین (10 نفر) و کنترل (10 نفر) تقسیم شدند. گروه کنترل تمرینات باشگاهی خود را سه جلسه در هفته به مدت شش هفته و گروه تمرینی علاوه‌بر تمرینات باشگاهی، تمرینات تناوبی با شدت معادل HRDP براساس روش-D-Max را اجرا ­کردند. برای تعیین تفاوت­های درون و میان‌گروهی به‌ترتیب از آزمون­های t همبسته و t مستقل استفاده شد. زمان رسیدن به خستگی (00/0P=) و لاکتات تولیدی (02/0 P=) فقط در گروه تمرینی به­طور معنا­داری افزایش داشت، اما بهبود عملکرد در هر دو گروه تمرین (02/0P=) و کنترل (04/0P=) مشاهده شد. همچنین گروه تمرینی به­طور معناداری تأثیرات بهتری را بر سطح لاکتات (01/0P=)، زمان رسیدن به خستگی (03/0P=) و عملکرد (00/0P=) بازیکنان فوتبال داشت. به­طور کلی به مربیان و بازیکنان ­فوتبال پیشنهاد می‌شود تا در کنار تمرینات باشگاهی خود، تمرینات تناوبی را با شدت معادل HRDP برگرفته از روش-D-Max برای رسیدن به اهداف تمرینی، به‌کار گیرند.

چکیده [English]

The aim of this study was the effect of 6 weeks of interval training based on heart rate deflection point (HRDP) extracted from D-Max method on blood lactate, performance and time to fatigue of young soccer players. 20 soccer players volunteered to participate in this study and were randomly divided into two groups: training (n=10) and control (n=10). Control group performed their club training 3 sessions a week for 6 weeks and training group conducted the interval training with equivalent intensity of HRDP based on D-Max method in addition to their club training. The dependent and independent t tests were used to determine intragroup and intergroup differences. The results showed that time to fatigue (P=0.00) and produced lactate (P=0.02) significantly increased only in the training group, but performance was improved in both training (P=0.02) and control (P=0.04) groups. Also, the training group showed significantly better effects on lactate (P=0.01), time to fatigue (P=0.03) and performance (P=0.00) in soccer players. Generally, coaches and soccer players are recommended to use interval training with equivalent intensity of HRDP extracted from D-Max method combined with their club training in order to achieve their training goals.
