Cycling is a great means of improving bone mineral density. Is this statement true or false?

The statement about cycling improving bone mineral density is false. While cycling offers numerous benefits, such as cardiovascular fitness, muscle strength, and improved joint mobility, it is primarily a non-weight-bearing activity. Bone mineral density is primarily enhanced through weight-bearing exercises, where the body supports its own weight, stimulating bone growth and maintenance.

Cycling, whether on a stationary bike or on flat surfaces, does not impose the same stress and forces on the bones as activities like walking, running, or resistance training, which are essential for stimulating bone density increases. Therefore, relying solely on cycling would not effectively enhance bone mineral density, especially in older adults who are at increased risk for bone density loss and fractures.

The other options present varying conditions for the benefits of cycling, but fundamentally, the nature of cycling as a non-weight-bearing exercise does not lead to improvements in bone mineral density, making the statement about its efficacy in this regard inaccurate.
