چکیده

هدف از پژوهش حاضر بررسی تأثیر شش هفته تمرین تناوبی شدید تحت شرایط میکروگراویتی بر تغییرات ساختاری غلاف میلین عصب رادیال موش‌های صحرایی نر می‌باشد. به این منظور تعداد 24 سر موش صحرایی نر نژاد ویستار بطور تصادفی به چهار گروه تقسیم شدند: 1) استراحت طبیعی(6=n) 2) استراحت میکروگراویتی شبیه‌سازی شده(6=n) 3) تمرین تناوبی شدید طبیعی(6=n) 4) تمرین تناوبی شدید میکروگراویتی شبیه‌سازی شده(6=n). آزمودنی‌ها به مدت شش هفته و هر هفته پنج جلسه، پروتکل تمرینی را اجرا کردند. 24 ساعت پس از آخرین جلسه‌ی تمرینی آزمودنی‌ها مورد نمونه‌گیری و مطالعه قرار گرفتند. نتایج نشان داد که درصد تغییر تراکم غلاف میلین در گروه تعلیق + تمرین به طور معنی داری(001/0≥p) بیشتر از سایر گروه‌ها بود (27/5±27/30). بنابراین به نظر می‌رسد که تمرین تناوبی شدید در شرایط میکروگراویتی شبیه سازی شده می‌تواند با افزیش تراکم غلاف میلین، نقش مهمی در بهبود وضعیت‌های بالینی بیماران عصبی و همچنین کاهش آثار جانبی نامطلوب محیط کم جاذبه (اختلالات عصبی- عضلانی) بر فضانوردان داشته باشد.

چکیده [English]

The purpose of this study was to investigate the effect of six weeks of HIIT under simulated microgravity condition on morphological changes of radial nerve myelin sheath in male rats. In present study, 24 male wistar rats were randomly selected and divided into four groups including: TS(training during suspension:n=6), CS(suspension:n=6), T(training:n=6), C(control:n=6). The training groups run on treadmill for six weeks (five days in week). 24 hours after the last training session, the animals were prepared for tissue samples. At the end of the experiment, changes in myelin sheath were measured by Luxol fast blue. Our results showed that the percentage of changes in myelin sheath in HIIT group under simulate microgravity (p≤0.001) was highest than other groups, significantly (30/27+5/27). Based on the results, HIIT under simulated microgravity condition affected on changes in myelin sheath, Therefore, it seems that can play an effective role in improvement of the clinical status of neurological patients and decrease side effects in Astronauts.
