Bone Response to Resistance and Impact Exercise (BRRIE) in Women on Antiresorptive Medications: A Randomized Controlled Trial
Abstract
Performing resistance training and impact exercise at a moderate to high intensity may help prevent bone loss. However, medications used to treat bone diseases such as osteoporosis reduce the activity of bone cells. The investigators are unsure whether bone cells will still respond to exercise in people on osteoporosis medications. Therefore, investigators have designed a study to compare bone response to moderate-high intensity exercise that involves resistance training and impact exercise versus posture and low intensity balance exercises. Women taking osteoporosis medication will be equally and randomly assigned to one of the exercise groups. There will be 23 participants per group and both exercise programs will be performed over a span of 6 months, twice weekly, for approximately 30-45 minutes per session. Investigators will measure sclerostin, a bone-related protein found in the blood, to see if there are any changes after 3 months of training. Higher levels of sclerostin may result in greater bone breakdown. It is expected that the moderate-high intensity exercise program will decrease sclerostin levels more than low intensity training. Further, changes in sclerostin levels during the 6-month exercise intervention will be explored. The effects of the exercise program on other bone markers in the blood, physical ability, and quality of life will be reported. The willingness of the participants to perform the exercise program and the safety of the exercises provided…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 26 participants or records.
