This study aimed to determine whether swimming could improve function of osteoarthritic joints in canine hip OA. Fifty-five dogs were categorized into three groups. The OA with swimming group (OA-SW; ), the healthy (non-OA; ) with swimming group (H-SW), and the healthy (non-OA; ) without swimming group (H-NSW). All animals were allowed to swim for a total of 8 weeks (2-day period, 3 cycles of swimming for 20 minutes, and resting period for 5 minutes in each cycle). Three ml of blood was collected every 2 weeks for evaluation of the levels of biomarkers for OA, including chondroitin sulfate epitope WF6 (CS-WF6) and hyaluronan (HA). Clinical evaluation of the OA-SW group found that most parameters showed improvement () at week 8 compared to pretreatment, while pain on palpation was improved () at week 6. The relative level of serum CS-WF6 in the OA-SW group was found to be significantly different () at weeks 6 and 8 compared with the preexercise. The levels of serum HA of the H-SW group in weeks 2–8 were significantly () higher than preexercise. Conclusion, swimming over 2-day period, 8 weeks continually, can improve the function of OA joint.
