چکیده

هدف از پژوهش حاضر مقایسه و ارتباط میان شاخص‌های آمادگی جسمانی و توانایی انجام کار با بیان a 133 miRدر آتشنشانان سازمان آتشنشانی بود.

مطالعه حاضر از نوع کاربردی و از نظر روش تحقیق، به صورت توصیفی-تحلیلی بود. جامعه آماری کلیه آتشنشنانان سازمان آتشنشانی شهر شیراز بودندکه از میان ایستگاه های 24 گانه، ایستگاه12 آتشنشانی که تمایل به همکاری داشتند،20نفر (10 نفر پست اداری ، 10 نفر پست عملیاتی) به روش نمونه‌گیری قابل دسترس انتخاب شدند. شاخص های آمادگی جسمانی ، توانایی انجام کار با پرسشنامۀ WAI و بیان miR-133a با روش Real-time PCR مورد بررسی قرار گرفت . تجزیه و تحلیل داده ها با استفاده از آزمون های شاپیرو-ویلک ، پیرسون و تی مستقل توسط SPSS27 انجام و سطح معنی داری05/0 P< در نظر گرفته شد.

میان بیان miR-133a با توانایی انجام کار و شاخص های آمادگی جسمانی در گروه های مورد مطالعه ارتباط معنی داری مشاهده نشد. همچنین تفاوت معنی داری درتوانایی انجام کار ، استقامت عضلانی میان تنه، استقامت عضلانی بالاتنه و انعطاف پذیری در گروه عملیاتی و اداری وجود نداشت، اما بین حداکثر اکسیژن مصرفی (03/0 P= ) و بیان miR-133a (02/0 P= ) اختلاف معنی داری در میان آتشنشانان در گروه های عملیاتی و اداری مشاهده گردید.

در آتش‌نشانان عملیاتی، کاهش miR-133a با افزایش Vo2max همراه است. پیشنهاد می‌شود برنامه‌های تمرینی منظم برای بهبود آمادگی قلبی‌تنفسی و مدیریت استرس شغلی تدوین گردد. تحقیقات بیشتر برای درک رابطه بین miR-133a و آمادگی جسمانی ضروری است تا مداخلات بهداشتی مؤثرتری برای آتش‌نشانان طراحی شود.

چکیده [English]

Introduction: The aim of the present study was to compare and correlate physical fitness and work ability with the expression of miR-133a in firefighters of the fire department.

Methodology: The present study was of an applied type and descriptive-analytical in terms of research method. The statistical population was all firefighters of the Shiraz Fire Department, of which 20 (10 administrative posts, 10 operational posts) were selected from 24 stations and 12 fire stations that were willing to cooperate using the accessible sampling method. Physical fitness and work ability indices were examined using the WAI questionnaire and miR-133a expression was examined using the Real-time PCR method. Data analysis was performed using the Shapiro-Wilk, Pearson, and independent t-tests by SPSS27, and the significance level was considered to be P<0.05.

Results: No significant relationship was observed between miR-133a expression and work ability and physical fitness indices in the studied groups. There was also no significant difference in work ability, core muscular endurance, upper body muscular endurance, and flexibility between the operational and administrative groups, but a significant difference was observed between the maximum oxygen consumption (P=0.03) and miR-133a expression (P=0.02) among firefighters in the operational and administrative groups.

Conclusions: In operational firefighters, a decrease in miR-133a is associated with an increase in Vo2max. It is suggested that regular exercise programs be developed to improve cardiorespiratory fitness and manage occupational stress. Further research is necessary to understand the relationship between miR-133a and physical fitness in order to design more effective health interventions for firefighters.
