Comparing exercise types for knee arthritis relief

This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This study is testing whether different types of exercise—aerobic (heart-pumping) activity, strength training, or a combination of both—can help reduce pain and improve muscle function in people with knee osteoarthritis. Researchers will measure how well each type of exercise helps your muscles use oxygen, builds strength, reduces pain, and improves your ability to move and perform daily activities.

Knee osteoarthritis causes pain and stiffness that can limit your daily life, and while exercise is known to help, doctors aren't sure which type of exercise works best. This study will help determine whether focusing on aerobic fitness, muscle strength, or a mix of both is most effective for managing your symptoms.

Do you qualify?

You likely qualify if…

you are between 45 and 65 years old
you have been diagnosed with knee osteoarthritis in both knees (grade 2 or 3 severity)
you have a body mass index below 30
you are willing to commit to supervised exercise three times per week for 6 weeks
you have not received treatment for knee osteoarthritis in the past 6 months

You likely don't qualify if…

you have other orthopedic or rheumatologic problems in your lower legs or circulation issues
you have uncontrolled high blood pressure, lung disease, or diabetes
you have a neurological condition or cognitive impairment that would prevent you from safely exercising
you are already very active (exercising more than 600 minutes per week)
you have a significant knee extension deficit (difficulty straightening your knee)

What participation looks like

You will visit the research facility three times per week for 6 weeks (18 sessions total), where you'll complete one of three supervised exercise programs: aerobic cycling, strength training, or a combination of both. Each session lasts about an hour and includes a warm-up, the main exercise, and a cool-down. You'll also do simple stretching exercises at home 3–5 days per week. The research team will check your progress at baseline, week 3, week 6, and week 10 to measure your pain, strength, and how well your muscles are working.
