Progressive high-impact training improved the patellar cartilage quality of the postmenopausal women who may be at risk of osteoporosis (bone loss) as well as at risk of osteoarthritis. This was found out in the study carry out in the Department of Health Sciences at University of Jyväskylä, Finland. The effects of high-impact exercise were examined on knee cartilages, osteoarthritis symptoms and physical function in postmenopausal women with mild knee osteoarthritis. The study was conducted in cooperation with the Central Finland Central Hospital and the Department of Medical Technology, Institute of Biomedicine in University of Oulu in Finland.
Eighty eligible postmenopausal women from 50 to 65 -years of age and having knee pain on most days of the month, were enrolled into the study and randomly assigned into either a training group or a control group. The mild knee osteoarthritis of all participants was confirmed prior the randomization and intervention by radiographs. Training group exercised according a supervised progressive high-impact exercise program three times a week for 12-months, while the control group continued their normal physical activity. The effects of exercise on patellar cartilage texture and the amount of liquid was measured by T2 relaxation time at MRI imaging.
