Abstract
One of the most frequent musculoskeletal disorders in adults is osteoarthritis. occurs due to degenerative processes in the joints, through wear and tear mechanism, especially in the articular cartilage. The treatment options for osteoarthritis are classified into symptomatic therapy and disease modification therapy. However, many people who suffer from osteoarthritis have limitations in their daily activities, thus preventing them from modifying their lifestyles. Many types of exercise exist, yet the best exercise for symptomatic osteoarthritis hasn’t been found. In daily practices, Moderate Intensity Continuous Training (MICT) is the most recommended and commonly performed type of exercise performed by patients with OA because MICT has a range of cardiovascular health benefits and maintains body weight. However, MICT may not provide enough stimulus to increase lower muscle mass and strength, articular changes that contribute to the pain, stiffness, and functional limitations seen in patients with knee OA. Some new studies found that High-Intensity Interval Training (HIIT) is more efficient than MICT as a classic exercise after six to eight weeks of exercise. HIIT in symptomatic osteoarthritis can significantly improve a patient’s fitness, visceral fats, and symptoms. HIIT can be a treatment option in resolving symptomatic knee osteoarthritis.
