Which option constitutes a special consideration for osteoporosis guidelines?

• A. Heavy resistance training
• B. Cycle, low-impact or step aerobics
• C. Sprint intervals
• D. High-impact plyometrics

Answer: (B)

In osteoporosis guidelines, safety and fracture risk reduction guide exercise selection. The best approach emphasizes low‑impact activities that still provide some weight-bearing or mechanical loading without exposing fragile bones to high forces. Cycling and low‑impact or well‑modified step aerobics fit this need because they deliver cardiovascular benefit and bone-loading stimulus while minimizing jarring impacts. Step aerobics can be adjusted with a small step height and controlled landings to stay low‑impact, and cycling is inherently non–weight bearing, reducing load on the spine and hips.

High‑impact alternatives like sprint intervals or high‑impact plyometrics impose greater forces on the bones and surrounding structures, increasing fracture risk and thus are not preferred for osteoporosis without careful medical/fitness supervision. Heavy resistance training can be beneficial when supervised and properly progressed, but the question focuses on a special consideration for osteoporosis, which is best addressed by prioritizing safer, low‑impact options such as cycle, low‑impact, or step aerobics.
