Brief summary
For the many individuals with established osteoporosis who will not, or cannot take medication there are currently no recommended therapeutic alternatives. Calcium and vitamin D are vital but insufficient therapies and are similarly limited by poor patient compliance. Recent evidence suggests high intensity exercise is an effective stimulus for bone. Whole body vibration (WBV) can also be anabolic to the musculoskeletal system. Early research has shown that WBV is a simple, passive therapy with greater appeal to the target population than exercise or drugs. This trial will be the first to use rigorous methods to examine the effects of WBV alone, and in combination with high-intensity exercise, in participants on and off bone medications, to improve risk factors for hip fracture (bone density, balance and muscle strength).
Interventions
Arm 1. WBV: Participants will stand on the 30 Hz WBV device installed in their home for 10-minutes 5 days per week for 9 months. Compliance is recorded by the device. Arm 2. HiRIT: Participants will attend Griffith University for a 30-minute high intensity resistance and impact training (HiRIT) session, supervised by a trained exercise physiologist or exercise scientist, twice per week for 9 months. A participant diary will be completed every session. Arm 3. HiRIT + WBV: Participants will stand on the WBV device installed in their home for 10-minutes 5 days per week for 9 months, and attend Griffith University for a 30-minute high intensity resistance and impact training (HiRIT) session, supervised by a trained exercise physiologist or exercise scientist, twice per week for 9 months. Compliance is recorded by the device, and a participant diary will be completed every session.
