چکیده
افزایش همزمان قدرت و استقامت از عوامل اساسی رسیدن پاروزنان به اوج عملکرد است. هدف اصلی این تحقیق مقایسۀ اثر هشت هفته تمرین مقاومتی- پاروزنی با تمرینات پاروزنی بر برخی ویژگی‌های فیزیولوژیکی و عملکردی پاروزنان بود. بدین منظور شانزده نفر از پاروزنان دختر دراگون بت به‌صورت هدفمند انتخاب و به دو گروه تمرینات مقاومتی- پاروزنی (9 n=) و تمرینات پاروزنی (7n=) تقسیم شدند. پاروزنان گروه ترکیبی به مدت هشت هفته و هر هفته سه جلسه و هر جلسه 120- 90 دقیقه در تمرینات پاروزنی به‌همراه تمرینات مقاومتی شرکت کردند. گروه پاروزنی در همین زمان فقط به تمرینات پاروزنی پرداختند. توان بی‌هوازی بالاتنه، حداکثر اکسیژن مصرفی، قدرت پنجه، یک تکرار بیشینۀ حرکات پرس سینه و پارو و عملکرد پاروزنی ۵۰۰ متر قبل و پس از دورۀ تمرینی اندازه‌گیری شد. به‌منظور مقایسۀ تغییرات بین دو گروه از روش آماری کوواریانس استفاده شد. سطح معناداری برابر با 05/0 در نظر گرفته شد. حداکثر توان بی‌هوازی بالاتنه و حداکثر اکسیژن مصرفی (به‌ترتیب 40 و 23 درصد) در گروه ترکیبی افزایش نشان داد که نسبت به گروه کنترل معنادار بود )001/0 = (P. قدرت پنجه در گروه ترکیبی نسبت به گروه کنترل تغییر معناداری نیافت )1/0 = (P. در مقادیر یک تکرار بیشینۀ حرکات پرس سینه و پارو در گروه ترکیبی (به‌ترتیب 36 و 16 درصد) افزایش و بهبود شایان ملاحظه‌ای در زمان پاروزنی 500 متر در گروه ترکیبی (5 /17 درصد ) نسبت به گروه پاروزنی حاصل شد )02/0 = (P. به‌نظر می‌رسد شرکت در تمرینات مقاومتی به‌همراه تمرینات پاروزنی می‌‌تواند با افزایش توان هوازی، توان بی‌هوازی و قدرت پاروزنان، سبب بهبود عملکرد شود.

چکیده [English]
Concurrent increase in strength and endurance is one of the main factors of reaching the peak performance in paddlers. The aim of this study was to compare the effect of 8 weeks of resistance-paddling training and paddling training on some physiological characteristics and performance of paddlers. 16 female dragon boat paddlers were selected purposively and divided to resistance-paddling training group (n=9) and paddling training group (n=7). Resistance-paddling group participated in padding training along with resistance training for 8 weeks, 3 sessions per week, each session 90-120 min. The paddling group performed paddling training at the same time. Upper body anaerobic power, VO2max, hand grip strength, 1-RM of bench press and paddling and 500-meter paddling performance were measured before and after 8 weeks of training. ANCOVA was used to compare changes between the two groups and the significance level was 0.05. The results showed a significant increase in upper body anaerobic power and VO2max (40% and 23% respectively) in resistance-paddling training group which was significant compared with the control group (P=0.001). Hand grip strength did not change significantly in resistance-paddling group compared with the control group (P=0.1). 1-RM of bench press and paddling increased (36% and 16% respectively) in resistance-paddling group. The time of 500-m paddling performance significantly improved in resistance-paddling group (17.5%) compared with the paddling group (P=0.02). It seems that resistance-paddling training can improve performance through increased aerobic power, anaerobic power and paddlers' strength.
