Objective: The musculoskeletal abnormalities are characterized as any tissue damage of the musculoskeletal system and nerves, which disrupts the function of the limb. Thus, the current study aimed to compare the musculoskeletal abnormalities of the upper trunk between freestyle, Greco-Roman, and Chokheh wrestlers.
Methods: This descriptive-analytical study was conducted on 15 freestyle wrestlers, 15 Greco-Roman wrestlers, and 15 Chokheh wrestlers in north Khorasan Province, Iran, in 2019. The study subjects were purposively selected from an available community. Kyphosis and lordosis angles evaluation was performed using a flexible ruler. The forward head and forward shoulders performance from side view were evaluated with digital cameras, and angles were analyzed by AutoCAD software. For data analysis, Analysis of Variance (ANOVA) and Shafa's posthoc test.
Results: According to the achieved results, in all musculoskeletal abnormalities of the upper trunk, except for the lumbar lordosis, freestyle wrestlers had a higher frequency of abnormalities, compared to the Greco-Roman and Chokheh wrestlers (P<0.05). Furthermore, lumbar lordosis was higher in Greco-Roman wrestlers compared to the freestyle and Chokheh wrestlers (P<0.05).
Conclusion: The obtained data indicated that abnormalities in the head, shoulders, and spine areas could be affected by the type of sport. Maintaining an inappropriate posture for a long time also impacts the development of musculoskeletal abnormalities.
