We are exploring a unique weight-training program for men and women 55 years or older with knee osteoarthritis (OA) that emphasizes high-speed movmenents. We believe that the speed at which muscles move may be more important to the improvement of muscle performance, function and pain than how strong the muscles are. We are comparing high-speed power training with traditional strength training to determine which method has the greatest effects on muscle strength, muscle power, speed of movement, functional performance and pain. We believe that high-speed training will improve these measures to a greater extent than simply training for increased muscle strength.

Further study details as provided by University of Missouri-Columbia:

Primary Outcome Measures:
  • Strength and power [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
    The strength of the lower limb muscles will be measures using Keiser pneumatic leg press and knee extension exercise machines. The Keiser machines allow for the specific measurement of the contributions of force and velocity to the development of power, which will reveal whether the high-speed training protocol impacts speed-related measures of muscle performance.

Secondary Outcome Measures:
  • Function [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
    Measures of mobility and function were evaluated using the 400-m Walk, Berg Balance Scale and timed chair rise which assess walking endurance, balance, and stregnth, respectively, all important variables for mobility

Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: High-speed power training
Volunteers randomized into SHPT will be exercised 3 times per week for 12 weeks. Each training session will consist of 3 sets of 12 to 14 repetitions at 40% of maximal strength for leg press (LP) and seated knee extension (KE) exercises.
Other: weight training
Weight training performed 3 times a week for 12 weeks
Active Comparator: Slow-speed strength training
Volunteers randomized into STR will be exercised 3 times per week for 12 weeks. Each training session will consist of 3 sets of 8 to 10 repetitions at 80% of maximal strength for LP and KE exercises.
Other: weight training
Weight training performed 3 times a week for 12 weeks
No Intervention: Control
Volunteers randomized into CON will undergo a placebo exercise intervention consisting of lower extremity range of motion and flexibility exercises performed 2 times per week with the assistance of the research staff.
