چکیده

هدف این پژوهش بررسی تأثیر یک دورۀ تمرین اینتروال و تیپرپلکانی بر تغییرات وزنی و عملکرد استقامتی رت‌های نر در حال بالیدگی بود.
در این مطالعۀ تجربی، 40 سر موش­ صحرایی ویستار نر سه‌هفته­ای به‌طور تصادفی به گروه­های کنترل و تمرین تقسیم شدند. گروه تمرین پس از پایان دورۀ شش‌هفته­ای تمرین اینتروال فزاینده به سه گروه تیپر سه‌هفته­ای کاهش شدت، تواتر و تکرار تقسیم شدند. وزن و شاخص­های عملکردی ارزیابی شدند. یافته­های پژوهش با استفاده از آنالیز واریانس دوطرفه و آزمون LSD در سطح 05/0α≤ تجزیه‌وتحلیل شد.
نتایج نشان داد تفاوت معنا­داری بین زمان­ خستگی گروه­های مختلف تیپر با یکدیگر (001/0P≤) و هفته­های تیپر با دورۀ اینتروال (008/0P≤) وجود دارد. تیپر شدت با کاهش 57/28 درصدی در شدت تمرین، بهترین میانگین زمان خستگی، مسافت طی‌شده در آزمون و عملکرد (Pri) را نسبت به سایر گروه­­ها داشت. همچنین مسافت طی‌شده در آزمون و زمان واماندگی در هفتۀ دوم تیپر به حداکثر خود رسید.
براساس نتایج پژوهش حاضر، تیپر پلکانی شدت موجب افزایش 13/52 درصدی عملکرد استقامتی می­شود. همچنین دو هفته کاهش بار تمرینی آثار هم‌افزایی مؤثرتری با مداخله بر تغییرات وزنی و زمان واماندگی در پی دارد.

چکیده [English]

The aim of this study was to investigate the effect of a period of interval training and step taper on weight changes and endurance performance in male rats during puberty. In this experimental study, 40 male Wistar rats (3 weeks old) were randomly divided into exercise and control groups. After 6 weeks of incremental interval training, exercise group was divided in to 3 groups of 3-week taper with Intensity, frequency and repetition. Weight and performance indexes were evaluated. Data were analyzed using two-way ANOVA and LSD test at α≤0.05. The results showed a significant difference in fatigue time among all different taper groups (P≤0.001) and also between taper weeks and interval period (P≤0.008). Intensity taper with 28.57% reduction in intensity had the best average fatigue time, distance traveled in the test and performance (Pri) compared with other groups. Also, the distance traveled in the test and exhaustion time reached their maximum in the second week of taper. The results of the present study suggested that intensity step taper increased endurance performance by 52.13%. Also, 2 weeks of reduction in exercise load can have more effective synergic effects through an intervention in weight changes and exhaustion time.
