چکیده

هدف این مطالعه مقایسۀ تأثیر سه شیوۀ تمرین ترکیبی بر غلظت تستوسترون، کورتیزول، نسبت تستوسترون به کورتیزول و قدرت عضلانی زنان سالمند بود. به این منظور 40 نفر از زنان سالمند (دامنۀ سنی 82/0±34/60 سال) به‌طور تصادفی ساده در یکی از چهار گروه تمرین استقامتی+ قدرتی (E+S) (n=9)، قدرتی+ استقامتی (S+E) (n=10)، ترکیبی چرخشی (ACT) (n=12) و کنترل (n=9) قرار گرفتند. برنامه­های تمرینی به مدت 8 هفته و 3 روز در هفته انجام گرفت. برنامۀ­ تمرین استقامتی شامل کار روی دوچرخۀ ثابت و برنامۀ تمرین قدرتی شامل چندین تمرین منتخب بالاتنه و پایین‌تنه بود. از آزمون تی وابسته و آزمون آنالیز واریانس یکطرفه به‌منظور تجزیه‌وتحلیل داده­ها استفاده شد. نتایج نشان داد 8 هفته تمرین تغییری در میزان تستوسترون گروه S+E و ACT نداشت، اما کاهش معناداری در میزان تستوسترون در گروه E+S مشاهده شد (007/0=P). نتایج نشان‌دهندۀ وجود اختلاف معنادار در میزان تستوسترون بین گروه‌های E+S و ACT بود (01/0=P ). علاوه‌بر این، در میزان کورتیزول و نسبت تستوسترون به کورتیزول (T/C) پس از تمرین تغییر معنا­داری مشاهده نشد. همچنین، افزایش معنادار قدرت بالاتنه فقط در گروه‌های E+S و ACT و قدرت پایین‌تنه در همۀ گروه‌های تمرین مشاهده شد. با توجه به عدم تغییر شایان توجه در سطح پایۀ هورمون­ها در سه گروه تمرین ترکیبی، این افراد وضعیت کاتابولیکی مزمنی را تجربه نکردند و از آنجا که قدرت در همۀ گروه‌ها افزایش یافته است، به‌نظر می­رسد بین وضعیت هورمونی و کسب قدرت در این مطالعه رابطه­ای وجود ندارد.

چکیده [English]

The aim of this study was to compare the effects of three types of combined training on testosterone and cortisol concentration, testosterone/cortisol ratio and muscular strength in elderly women. 40 elderly women (age range: 60.34±0.82 years) were randomly divided into four groups: endurance + strength (E+S) (n=9), strength + endurance training (S+E) (n=10), alternative concurrent training (ACT) (n=12) and control (n=9). The training program was performed for 8 weeks, 3 days per week. Endurance training protocol included performance on a cycle ergometer and strength training protocol involved several selected upper and lower body workouts. Paired samples t test and one-way ANOVA were used to analyze data. The results showed that 8 weeks of training did not change testosterone in S+E and ACT groups but a significant decrease was observed in testosterone in E+S group (P=0.007). In addition, results showed a significant difference in testosterone between E+S and ACT groups (P=0.01). In addition, no significant changes were observed in cortisol and testosterone/cortisol ratio after the training. Also, there was a significant increase in upper body strength only in E+S and ACT groups and in lower body strength in all groups. As there were no significant changes to basal hormones in 3 combined training groups, these subjects experienced no chronic catabolic state. Since strength increased in all groups, it seems that there was no relationship between hormonal status and the strength gains in the present study.
