Which two practices are listed as ways athletes stimulate bone formation?

• A. Being active on your feet and varying exercises that stress all areas of bone
• B. Sitting and performing repetitive same movement
• C. Avoiding weight-bearing activities
• D. Highly specialized, single-exercise routines

Answer: (A)

Bone adapts to the mechanical stress it experiences, so loading the skeleton through activity promotes bone formation. Being active on your feet provides weight-bearing stimulus that loads bones in the legs, hips, spine, and feet, encouraging new bone growth where the forces are applied. Adding variety in training means different bones and regions are loaded in multiple directions and magnitudes, leading to broader and more uniform bone remodeling rather than growth at just one site. Sitting with repetitive, the same movement offers little or highly repetitive stress, so the stimulus for bone formation is minimal. Avoiding weight-bearing activities reduces the loading signal bones need to form more matrix, which can lead to weaker bone over time. Highly specialized, single-exercise routines concentrate load on a few areas and miss others, limiting overall bone adaptation.
