چکیده

زمینهوهدف:کاهش فعالیت جسمانی، چاقی و اضافه وزن از جمله عوامل مهم افزایش سطوح چربی خون می باشند. تاثیر متقابل این عوامل بر هم و در پاسخ به تمرینات ورزشی، می تواند با تغییرات شبانه روزی اعمال فیزیولوژیک بدن رابطه داشته باشد. پژوهش حاضر با هدف بررسی تاثیر درس تربیت بدنی عمومی (1) در نوبت صبح و عصر بر توان هوازی، ترکیب بدن و نیمرخ لیپیدی و لیپوپروتئینی خون دانشجویان غیر ورزشکار دانشگاه شهید باهنر کرمان انجام شد. روشتحقی: 15 آزمودنی گروه عصر، 14 آزمودنی گروه صبح و 15 آزمودنی گروه کنترل، از بین دانشجویان غیر ورزشکاری که در حال گذراندن واحد تربیت بدنی عمومی (1) به صورت داوطلب انتخاب شدند. نمونه خون از آزمودنی ها در حالت ناشتا و در دو نوبت، قبل و بعد از 8 هفته مداخله گرفته شد. تغییرات نیمرخ لیپیدی سرم  )تری گلیسرید، کلسترول تام، لیپوپروتئین با چگالی بالا و لیپوپروتئین با چگالی کم( با روش آنزیماتیک مورد ارزیابی قرار گرفت. توان هوازی با آزمون کوپر و درصد چربی بدن با روش چین پوستی، در زمان های مشابه مورد اندازه گیری قرار گرفتند. نتایج با استفاده از آزمون تحلیل واریانس استخراج شدند و تغییرات در سطح 0/05≥p معنی دار تلقی گردید. یافتهها: نتایج نشان داد که 8 هفته درس تربیت بدنی عمومی (1) با تکرار یک جلسه در هفته در نوبت صبح و عصر، بر شاخص های کلسترول تام ، تری گلیسرید، لیپوپروتئین با چگالی بالا و لیپوپروتئین با چگالی کم و درصد چربی بدن تاثیر معنی داری ندارد؛ در حالی که توان هوازی دانشجویان را صرف نظر از وهله صبح یا عصر، به طور معنی داری (0/01>p) بالا می برد. نتیجهگیری: یک جلسه درس تربیت بدنی عمومی برای ارتقاء سامتی دانشجویان کافی نیست و ارائه آن در نوبت صبح و عصر تفاوتی ندارد.

چکیده [English]

Background and Aim: Decreasing in physical activity, overweight and obesity are the main causes of increasing serum lipid profile. The interaction of these factors with each other and in response to exercise could be correlated with physiologic circadian functions. The aim of present study was to compare the effects of 8-weeks of general physical education course (1) at the morning and evening on aerobic capacity, body composition, blood lipids and lipoproteins among non-athlete students in Shahid Bahonar University of Kerman. Materials and Methods: 15 (evening group), 14 (morning group) and 15 (control group) subjects among non-athlete general physical education course (1) students were selected as volunteer sample. Fasting blood samples (12 to14 hours) were taken two times before and also after 8 weeks of intervention. The changes in serum lipids profile (TC, TG, lipoprotein HDL and LDL) were determined by enzymatic methods. The aerobic power and percent body fat were measured by Cooper test and skinfold technique respectively. The data was analyzed by a mixed two-way Split Plot ANOVA test (SPANOVA) and the significant level set as p≤0.05. Results: The results indicated that 8 weeks of general physical education course (1) (one session in every week) had no significant effect on blood factors (TC, TG, HDL and LDL) and percent body fat (p>0.05). But, aerobic power of students
regardless of time during the morning and evening were significantly increased (p<0.01). Conclusion: One session of general physical education course (1) would not be enough to improve student’s health, moreover there is no difference affect of performing these courses during the morning and the evening time.
