Outline of Final Research Achievements

We evaluated the effects of exercise training on cartilage metabolism by systemic biomarkers. Females were classified into pre-radiologically defined osteoarthritis [Kellgren-Lawrence (K-L) grade<2] or radiologically defined osteoarthritis (K-L grade>1). After a combination of aerobic, resistance, flexibility, and balance exercise trainings was assigned for 90 minutes once a week during 12 weeks, they were followed up during subsequent 12 weeks. In K-L<2 group (n=23), the training resulted in a significant decrease in the collagen degradation evaluated by carboxy-telopeptide of type II collagen at 1, 2, 4, 8, and 24 weeks as well as by collagenase-generated neoepitope of type II collagen at 12, 20, 24 weeks. In K-L>1 group (n=8), no favorable effect by the training was found on cartilage metabolism evaluated by the biomarkers of type II collagen, whereas cartilage oligomeric matrix protein (degradation marker) increased at 1, 2, 20, and 24 weeks after the initiation of intervention.
