Finding the Optimal Resistance Training Intensity For Your Bones

Status Recruiting

Clinical Trial Summary

Osteoporosis is a bone disease that can result in fractures, disability and an increased risk of premature death. Exercise is recommended for fall and fracture prevention, but health care professionals often recommend walking or lower intensity community exercise classes, which may not be effective for building bone. Further, individuals with osteoporosis are often told to avoid lifting or moving in certain ways, which creates fear and activity avoidance. Conversely, research suggests that to stimulate bone, you need higher loads on bone, with either higher intensity resistance training or impact exercise - the types of things people with low bone mass are told to avoid. Our study will examine different types of exercise intensity and how they translate to building bone in people with low bone mineral density (BMD).

Clinical Trial Description

The FORTIFY Bones study will compare the effect of supervised twice-weekly progressive resistance training (PRT) at moderate or high intensity for one year to a home posture and balance exercise program on lumbar spine bone mineral density (BMD), in individuals with low bone mass not taking osteoporosis medication. As secondary analyses, we will examine the differences between each resistance training intensity and home exercise, and between resistance training intensities on all outcomes. Participants will be randomized to one of three exercise programs to be completed twice weekly: posture and balance exercise program at home, in-person, supervised progressive resistance training at 70% of estimated 1 Repetition Maximum (1RM) intensity, or in-person, supervised progressive resistance training at an 85% estimated 1RM intensity. The study is a multi-centre trial that will take place at the University of Waterloo, Toronto General Hospital, and the University of Saskatchewan. The long-term goal of this study is to generate evidence to support decision-making on the type of exercises for people with osteoporosis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
