A new study published in The BMJ indicates that aerobic exercise is the most effective physical activity for managing knee osteoarthritis. The review analyzed 217 clinical trials involving over 15,000 participants, focusing on various exercise types including walking, cycling, and swimming. The findings show that aerobic activities significantly reduce knee pain, enhance physical function, and improve quality of life in both the short and mid-term. In contrast, other exercise forms like strength training provided more modest benefits and are recommended as supplementary to aerobic workouts. The study emphasizes that aerobic exercises are safe for individuals with knee osteoarthritis, as they help improve blood circulation and joint lubrication while avoiding high-impact activities that could exacerbate pain. Experts recommend engaging in aerobic activities for 30-45 minutes, 3-5 times per week to effectively manage symptoms.
