چکیده

هدفازتحقیق حاضر،بررسیتأثیرهشتهفتهتمرینات سرعتی تکراریدرشرایطهایپوکسی و نورموکسی بر رکورد شنای شناگران نخبه دختر می باشد. تحقیق حاضر بر روی 30 شناگر نخبه دختر انجام گرفت که بصورت تصادفی در سهگروه10نفری شامل دو گروه تجربی(هایپوکسی و نورموکسی)و یک گروهکنترلقرار گرفتند. برنامه تمرینی برای هر دو گروه تجربی به مدت هشت هفته و هر هفته شامل دو جلسه تمرین با ارگومتر شنا و سه جلسه تمرین در استخر دنبال شد. پروتکل تمرینی برای دو گروه با شدت و مدت زمان یکسان (9 کوشش30 ثانیه ای با شدت 80 درصد حداکثر اجرا، همراه با دو دقیقه استراحت بین هر کوشش) بر روی ارگومتر شنا طراحی گردید، با این تفاوت که تمرینات گروه تجربی اول در شرایط هایپوکسی معادل 14 درصد fio2 انجام گردید. گروه کنترل در این مدت، فقط به اجرای 5 جلسه تمرین عادی شنای خود پرداختند. نتایج با استفاده از آزمون آماری تحلیل واریانس در سطح معنی داری
 05/0
p≤ تجزیه و تحلیل شدند. نتایج نشان داد که هشت هفته تمرینات سرعتی تکراری باعث بهبود رکورد شنای 100متر(013/0=P) و شنای 200متر (009/0=p) در شرایط هایپوکسی نسبت به نورموکسی می شود.

چکیده [English]

The aim of this study was to compare the effect of 8 weeks of repetitive sprint training in hypoxia and normoxia conditions on swimming record of female elite swimmers. The subjects included 30 female elite swimmers who were randomly divided into 3 groups (each group 10 subjects):  2 experimental groups (hypoxia and) and one control group. Training protocol was administered to both experimental groups for 8 weeks, 2 sessions per week with swimming ergometer and 3 sessions in the swimming pool. The protocol was designed for both experimental groups with similar intensity and duration (nine 30-sec. attempts at the intensity of 80% of maximum performance with two minutes of rest) on swimming ergometer. Hypoxia group performed the training in hypoxia condition with %14 of Fio2. The control group had only 5 session of regular swimming in the pool. Results were analyzed using ANOVA at P≤0.05. The results showed that 8 weeks of repeated sprint training improved 100 m swimming record (P=0.013)  and 200 m swimming record (P=0.009) in hypoxic condition compared with normoxia condition.
