Which activity is most appropriate to include in a lesson to illustrate how to improve bone density?

• A. brisk walking.
• B. cycling on a stationary bike.
• C. swimming laps.
• D. jumping rope on a soft mat.

Answer: (A)

When teaching how bone density changes in response to activity, the key idea is that bones adapt to the mechanical loads they experience. Weight-bearing, loading activities stimulate bone remodeling, leading to higher bone density over time. Brisk walking provides a safe, accessible weight-bearing load that travels through the bones with each step. This mechanical stimulus is enough to illustrate how bone density can improve through regular activity, making it a solid, practical example for most learners and settings. In contrast, cycling on a stationary bike and swimming involve little to no weight bearing on the skeleton, so they don’t provide the loading necessary to stimulate bone density changes. Jumping rope can be high-impact and beneficial for bone loading, but on a soft mat the actual forces are reduced, and it may not be as suitable for all students in a general lesson.
