چکیده

هدف پژوهش حاضر بررسی اثرات یک دوره تمرین عضلات دمی در ارتفاع بر انرژی مصرفی دمی، اشباع اکسیژن سرخرگی و عملکرد دوندگان تیم ملی استقامت بود.12مرد دونده استقامت تیم ملی (سن14/3±41/24سال، قد23/4±50/180سانتی‌متر، وزن 46/3± 75/66 کیلوگرم، BMI07/1±53/20درصد) در شرایط هایپوکسی به طور تصادفی به دو گروه تمرین عضلات دمیIMTو کنترل تقسیم شدند. از آزمودنی‌ها آزمون‌های دوی1500متر، حداکثر قدرت عضلات دمی(S-Index)، انرژِی مصرفی عضلات دمی و SpO2 قبل و 24ساعت بعد انجام شد. برنامه تمرینی شامل تمرینات مشابه تداومی، تناوبی، هوازی و مقاومتی برای هر دو گروه بود. دوندگان، به طور میانگین 16جلسه در هفته به مدت چهار هفته زندگی در ارتفاع، تمرین در ارتفاع و تمرین در پایین (اجرای3 جلسه تمرین فقط روزهای زوج در ارتفاع پایین و ادامه تمرینات به همراه خواب در ارتفاع بالا)در تمرینات حضور یافتند. تمرینات عضلات دمی برای گروه IMT شامل30 تکرار با بینی بسته 2 بار در روز (صبح و عصر) 7 روز هفته به مدت چهار هفته با50% S-Index اجرا گردید. برای تحلیل داده‌ها از روش آماری تحلیل واریانس با اندازه‌گیری مکرر در سطح معنی‌داری (05/0P≤) استفاده شد. تمرین عضلات دمی منجر به کاهش معناداری در زمان دوی 1500 متر، افزایش قدرت عضلات دمی از قبل تا بعد از تمرین و عدم تفاوت بین گروهی در انرژی مصرفی دو گروه شد. تفاوت معناداری SpO2 مشاهده نگردید (05/0P≤). به طور کلی به نظر می‌رسد استفاده از تمرین عضلات دمی به همراه تمرین اختصاصی در شرایط هایپوکسی، موجب افزایش قدرت عضلات دمی، بهبود کار تنفسی، کاهش میزان تهویه و کاهش زمان دوی 1500 متر در ارتفاعات پایین‌تر می‌گردد.

Effect of inspiratory muscle training at high altitude on energy cost, arterial oxygen saturation and 1500m performance of national team's endurance runners

چکیده [English]


Purpose: The aim of this study was to investigate the effect of inspiratory muscle training at high altitude on Energy cost,
peripheral capillary oxygen saturation and 1500m performance among endurance runners. Methods: The study was
carried on a group of Twelve endurance male runners (age: 244.41±3.14yrs, height: 180.5±4.23cm, weight: 66.75±3.46
kg, Body mass index: 20.53±1.07) among Iranian national team were randomly divided into case IMT training and control
group in hypoxic condition. Exhaustive testing 1500m, energy coast, strength Index and arterial oxygen saturation tests
were taken before and 24hour after. Training program include same continues, interval, aerobic and resistance training for
two groups. Runners performed 16 training session per week in high live train high and low (LHTH,L) within four weeks
(just 3 training sessions per week at even days performed at low altitude). Results: Data were analyzed by analysis of
ANOVA repeated measure (P≤0.05). Inspiratory muscle training at hypoxia due to significant decrease in 1500m running
time, inspiratory muscle strength and Energy coast in both group, but the differences in peripheral capillary oxygen
saturation were not significant (P≤0.05). Conclusions: This study suggests that using inspiratory muscle training along
with specified training in hypoxia increases inspiratory muscle strength and reduction in the work of breathing meanwhile
it decreases ventilation and 1500meter running time in lower altitude.
