چکیده:
Clinical experiences indicate that aquatic exercises may have advantages for osteoarthritis
patients. The purpose of this study was to examine the effects of aquatic exercise training on the
knee pain and its symptoms as well as on the motor performance associated with daily living
activities (ADL), sport-recreational activities, and the quality of life in men over 50. 30 men over
50 years old who suffered from knee osteoarthritis were selected voluntarily and were randomly
assigned to aquatic exercise therapy and control groups. The means and standard deviations of
age, height and weight of participants in each group were 54.26 ± 3.08 and 57.6 ± 5.76 yr; 169 ±
4.99 and 168.13 ± 4.76 cm; and 76.33 ± 8.11 and 71.53 ± 8.09 kg, respectively. Aquatic exercise
training was carried out 3 times per week for 6 weeks. Knee pain, symptoms, motor function in
daily activities and sport- recreation and quality of life were measured before and after exercise
training. Results showed that the knee pain, symptoms, motor function in daily and sports –
recreational activities and quality of life after the exercise protocol significantly improved in the
aquatic exercise group (P < 0.05); however, there was no significant change in control groups
from pre to post-test (p> 0.05). The results showed that aquatic exercises, as a safe and effective
exercise method, could be incorporated to improve the pain, motor functions and quality of life in
over-50-year-old males with knee osteoarthritis.
شواهد بالینی نشان میدهد که تمرین در آب میتواند برای مبتلایان به استئوآرتریت مفید باشد. هدف پژوهش حاضر، بررسی آثار برنامه تمرین ورزشی در آب بر میزان درد زانو، علائم بیماری، عملکرد حرکتی در فعالیت های روزانه و ورزشی - تفریحی (DHI) وکیفیت زندگی مردان بالای ٥٠ سال مبتلا به استئوآرتریت زانو بود. تعداد ٣٠ مرد بالای ٥٠ سال مبتلا به استئوآرتریت زانو به صورت داوطلبانه ، به عنوان نمونه انتخاب شدند و در یکی از دو گروه تمرین در آب و شاهد به صورت تصادفی قرار گرفتند. میانگین و انحراف استاندارد سن در دو گروه به ترتیب ٣/٠٨±
٥٤/٢٦ و ٥/٧٦±٥٧/٦ سال، قد ٤/٩٩±١٦٩ و ٤/٧٦±١٦٨/١٣ سانتیمتر، وزن ٨/١١±٧٦/٣٣ و ٨/٠٩±٧١/٥٣ کیلوگرم بود. شرکت کنندگان گروه اول، برنامه تمرینی ورزش در آب را به مدت ٦ هفته و ٣ جلسه در هر هفته زیر نظر محقق انجام دادند. موارد ارزیابی در دو مرحله قبل و بعد از ٦ هفته شامل درد زانو، علائم ، عملکرد حرکتی فعالیت های روزانه و ورزشی - تفریحی و کیفیت زندگی بود. شدت درد زانو، میزان علائم بیماری، عملکرد حرکتی در فعالیت های روزانه و ورزشی-تفریحی و کیفیت زندگی پس از اجرای پروتکل به میزان معنیداری در گروه تمرین در آب بهبود یافته بود (٠٠٥>p)، در حالی که در گروه کنترل تغییرات معنیداری در هیچ یک از متغیرها مشاهده نشد (pB٠٠٥).
نتایج نشان داد که برنامه تمرینی ورزش در آب می تواند به عنوان یک روش تمرینی ایمن و مؤثر در بهبود درد، علائم ، عملکرد حرکتی و کیفیت زندگی مردان بالای ٥٠ سال دارای استئوآرتریت زانو مورد توجه قرار گیرد.
خلاصه ماشینی:
"Results showed that the knee pain, symptoms, motor function in daily and sports – recreational activities and quality of life after the exercise protocol significantly improved in the aquatic exercise group (P < 0.
Lim, Tchai, and Jang (2010) designed two exercise programs, on land and in water to increase knee function and decrease body fat in obese patients with knee OA and concluded that body fat rate significantly decreased in the aquatic exercise group and pain, disability and quality of life significantly improved at the end of the protocol, even though, there was no significant difference in general traits in these people at first.
So, on the basis of the emphasis of aquatic exercise benefits for strengthening of muscles and reducing of probable sport injuries on joints, the aim of this study was the effects of aquatic exercise training on knee pain, symptoms, motor performance in daily and sports – recreational activities and quality of life in men over 50 years with knee osteoarthritis.

DISCUSSION Based on the findings and testing of these research hypotheses, results showed that pain, symptoms, motor performance in daily and sports-recreational activities and QOL in participants significantly improved in water exercise group after performing the protocol, while no significant changes were observed in any of these variables in the control group."
