The objective of the present study was to investigate deformational behavior and functional adaptation of articular cartilage by comparing the changes of biochemical osteoarthritis markers’ concentrations due to 30-min exercise after 12-weeks of regular high impact, impact or non-impact exercise. Blood samples were drawn from 44 healthy sedentary males immediately before, immediately after and 0.5 h after a 30-min moderate walking exercise. Osteoarthritis biomarkers’ (Serum COMP and CTX-I) concentrations were determined with enzyme-linked immunosorbent assay. After the first measurements, participants were randomly assigned to running, cycling, swimming, and control groups. All groups except for control group trained for 12 weeks. After 12-weeks, post tests were applied. Multivariate tests indicated a significant fatigue and resting effect on serum COMP concentration in all groups at pre- and post-tests. Therefore, pair wise comparisons were conducted in order to assess the differences across all groups and conditions. Results indicated significant differences in post-test measurements among phases of groups except for running group. However, fatigue or resting did not change the concentration of serum CTX-I in any groups during the tests. According to results, moderate walking activity has an influence on the increase of serum COMP concentrations of young sedentary men. However, 12 weeks regular weight-bearing high impact physical exercise decreases the deformational effect of walking activity by functional adaptation of articular cartilage to specific environmental requirements.
