The effect of aerobic exercise in water and land on inflammatory factors and its relationship with pain and function in overweight women with osteoarthritis of the knee

Knee osteoarthritis is a common knee joint disorder in the elderly, which involves a combination of factors including muscle weakness and changes within the joint, cartilage and bone, and is more common in overweight people. The aim of this study was to compare the effect of aerobic exercise in water and land on inflammatory factors and its relationship with pain and function in overweight women with osteoarthritis of the knee. Type of research: Quasi-experimental with pre-test and post-test design with control group.A total of ۲۴ women aged ۵۰-۶۰ years with osteoarthritis of the knee with mean weight (۷۱.۵۰ ۶۵ ۴.۶۵) and mean BMI (۲۵.۶۱ ۴۰ ۰.۴۰) were randomly divided into three groups: water exercise and onshore exercise. And controls (۸ people in each group). Exercises were performed for ۸ weeks (۳ sessions per week). Exercise in water and land was similar in terms of intensity, duration and frequency of exercise, and the intensity of exercise in water was continuously monitored by the researcher through manual measurement of heart rate (between ۱۴۰ and ۱۶۵). Before and after the training period, measurements of pain and motor function were performed on the subjects and blood samples were taken from three groups in the ۱۲-hour fasting condition and CRP and TNF-α levels were measured for each sample.Both types of exercises significantly reduced weight (۶۸.۱۲ ۳ ۳.۵۲), BMI (۲۴.۳۸ ۵۰ ۰.۵۰), pain and TNF-α and CRP levels and significantly improved motor function in women with knee osteoarthritis. (P <۰.۰۵ and t = ۰.۴۶), but no significant difference was observed between the effects of the two types of exercise (P> ۰.۰۵). Also, with decreasing TNF-α and CRP levels, pain decreased and motor function increased (t = ۰.۰۵ and t = ۰.۸۳, P <۰.۰۵).Exercise and weight loss in overweight women with osteoarthritis of the knee can reduce the inflammatory factors of pain and improve motor function. On the other hand, the variables (intensity, volume and frequency) between the two types of training in water and land were the same, probably no significant difference was observed between them.
