Study Summary

This trial will test if a "calcium clamp" can prevent bone breakdown during exercise by keeping calcium levels stable.

Who is the study for?
This trial is for healthy adults aged 60-80 who are currently taking bisphosphonates for osteoporosis. It's not suitable for those on other bone-affecting meds, with severe osteoporosis, uncontrolled high blood pressure, liver or kidney issues, diabetes, thyroid dysfunction, asthma or heart disease.Check my eligibility
What is being tested?
The study tests if using a 'calcium clamp' to prevent drops in serum calcium during exercise can also stop increases in markers of bone loss. Participants will receive either Calcium Chloride/Calcium Gluconate or a placebo while exercising.See study design
What are the potential side effects?
Potential side effects may include reactions at the infusion site due to calcium administration such as warmth or discomfort and possible changes in blood pressure. Long-term effects on bone health are being studied.
