بررسی اثر هشت هفته تمرین هوازی بر شاخص‎های عملکردی و دامنه حرکتی زانوی مردان سالمند فعال مبتلا به استئوآرتریت زانو

Background: Osteoarthritis is the most common joint disease, and the main histopathologic (pathology) tissue in the local destruction of the articular cartilage. This study was done to study the effect of eight weeks aerobic training on functional indicators and range of motion in active older men with knee osteoarthritis. Methods: Population includes active older men with knee osteoarthritis in West Azerbaijan. 20 active men who exercised at least twice a week, into two groups of 10 patients were randomly divided. The program was performed on the subjects for 8 weeks, three times a week. Functionality was measured using three tests, and goniometer was used to measure knee range of motion. Statistical analyses were performed using analysis of Covariance (ANCOVA), and paired-sample t-test through SPSS v.22 software. Results: Significant differences between the experimental and control groups in, knee range of motion (F= 6, p= 0.021), get up and go (F= 61, p= 0.0001), six minute walk (F= 361, p=0.000) and 8 feet time up and go (F= 561, p= 0.000) were observed. Also comparison within groups, in knee range of motion, get up and go, six minute walk and 8 feet time up and go showed a significant difference in the group aerobic (p= 0.0001). Conclusion: Overall, eight weeks Aerobic training significantly improves functional indicators and range of motion in active older men with knee osteoarthritis.
