Adherence
Outdoor green cycling (3x/week, 30-40 mins) significantly improves psychological well-being (reduced stress, mood disturbance, and depression; increased vigor) and glycemic control (HbA1c) compared to indoor stationary cycling in patients with knee osteoarthritis and type 2 diabetes.
If you have knee pain and diabetes, try cycling outdoors three times a week for 30-40 minutes. This specific type of 'green exercise' not only helps lower your blood sugar better than indoor cycling but also significantly reduces stress and improves your mood, making you more likely to stick with it. Start with supervision to ensure proper form and safety.
By 24 weeks, the OGC group showed a greater reduction in perceived stress (3.7 vs. 2.8, P = 0.007), and total mood disturbance (POMS) scores decreased more in the OGC group (-7.2 vs. -6.1, P = 0.030)... Participants in OGC group achieved significant decrease of HbA1c than participants in ISC group.
Why this rating
Randomized controlled trial with a reasonable sample size (N=82) and clear statistical significance, though limited by lack of blinding and short follow-up.
