آيا بين شاخص توده بدني و انحرافات وضعيتي در ورزشكاران پاورليفتينگ چاق و داراي اضافه وزن رابطه اي وجود دارد؟

Is there a relationship between body mass index and postural deviations in overweight and obese powerlifting athletes

انحرافات وضعيتي يكي از اختلالات عضلاني اسكلتي است، به نظر مي رسد برخي از تمرينات ورزشي و شاخص توده ي بدني بر روي وضعيت بدن تاثير گذار است، به همين روي هدف از پژوهش حاضر تعيين انحرافات پاسچرال در ورزشكاران پاورليفتينگ چاق و داراي اضافه وزن و مقايسه انحرافات پاسچرال بين اين دو گروه مي باشد. مواد و روش ها ورزﺷﮑﺎران ﻣﺮد ﭘﺎورﻟﯿﻔﺘﯿﻨﮓ 18 ﺗﺎ 35 ﺳﺎﻟﻪ ﺑﺮ اﺳﺎس ﺷﺎﺧﺺ ﺗﻮده ﺑﺪﻧﯽ ﺑﻪ ﯾﮑﯽ از دو ﮔﺮوه ﭼﺎق )25 ﻧﻔﺮ ﺑﺎ ﺷﺎﺧﺺ ﺗﻮده ﺑﺪﻧﯽ 30 و ﯾﺎ ﺑﯿﺶﺗﺮ( و ﯾﺎ اﺿﺎﻓﻪ وزن )50 ﻧﻔﺮ ﺑﺎ ﺷﺎﺧﺺ ﺗﻮده ﺑﺪﻧﯽ 25 ﺗﺎ 29/9( وارد ﺷﺪﻧﺪ و از آنﻫﺎ در ﺻﻔﺤﺎت ﺳﺎﺟﯿﺘﺎل و ﻓﺮوﻧﺘﺎل ﺑﺎ ﺑﻬﺮهﮔﯿﺮي از ﺧﻂ ﺷﺎﻗﻮﻟﯽ و ﯾﮏ ®symmetrograph ﺗﺼﻮﯾﺮﺑﺮداري ﺷﺪ، و ﺳﭙﺲ اﻧﺤﺮاﻓﺎت ﻧﻘﺎط ﮐﻠﯿﺪي ﭘﺎﺳﭽﺮ ﺑﺮ روي ﺗﺼﺎوﯾﺮ ﺑﺮرﺳﯽ ﮔﺮدﯾﺪ. ﯾﺎﻓﺘﻪﻫﺎ: ورزﺷﮑﺎران در ﻫﺮ دو ﮔﺮوه ﺗﻨﻬﺎ در ﺻﻔﺤﻪ ﻓﺮوﻧﺘﺎل در ﺳﻄﻮح ﺳﺮ، ﺳﺘﻮن ﻓﻘﺮات ﮔﺮدﻧﯽ و ﮐﻤﺮي داراي وﺿﻌﯿﺖ ﻃﺒﯿﻌﯽ ﺑﻮدﻧﺪ، ﻫﻢﭼﻨﯿﻦ اﻧﺤﺮاف وﺿﻌﯿﺘﯽ در ورزﺷﮑﺎران ﭼﺎق در ﺻﻔﺤﻪ ﺳﺎﺟﯿﺘﺎل در ﺳﻄﺢ ﺳﺘﻮن ﻓﻘﺮات ﺳﯿﻨﻪاي )0/008=P( و در ﺻﻔﺤﻪ ﻓﺮوﻧﺘﺎل در ﺳﻄﻮح ﺳﺎق )0/019=P( و ﮐﺘﻒ )0/029=P( در ﻣﻘﺎﯾﺴﻪ ﺑﺎ ورزﺷﮑﺎران داراي اﺿﺎﻓﻪ وزن ﺑﻪ ﺷﮑﻞ ﻣﻌﻨﺎداري ﮐﻢﺗﺮ ﺑﻮد نتيجه گيري يافته ها نشان داد كه انحرافات وضعيتي در ورزشكاران با شاخص توده بدني بيش تر، در برخي از سطوح كم تر مي باشد. به نظر مي رسد ورزشكاران چاق داراي حجم عضلات بيش تري بوده، و در برابر نيروهاي آسيب زننده محافظت شده بودند.

Postural deviations are one of the musculoskeletal disorders. It seems that some exercises and body mass index could affect postural conditions. Therefore, the purposes of the present study was to determine and compare the postural deviations in obese and overweight powerlifting athletes. Materials and Methods The male powerlifting athletes aged 18 to 35 years old entered to one of two groups based on their body mass index, 25 athletes for obese group (BMI: ≥ 30) and 50 athletes for overweight group (BMI: 25-29.9). The Sagittal and Frontal planes were photographed using a plumb line and a symmetrograph®, and then deviations of the postural key points were investigated on the images. Results Athletes in both groups only had normal posture in the head, cervical and lumbar vertebral levels in the frontal plane, and also the deviations in obese athletes in the sagittal plane at the level of the thoracic vertebral (P=0.008), and in the frontal plane at the level of the leg (P=0.019) and the scapula (P=0.029) were significantly lower than those of overweight athletes. Conclusion It is demonstrated that Postural deviations in powerlifting athletes with higher body mass index were lower in some levels. Interestingly, it seems that, the obese athletes may be protected against the injurious forces due to the greater muscle mass.
