Analyze mechanical stress on bone remodeling

Using the Bone Remodeling and Bone Functions knowledge points

• Bone tissue adapts to mechanical stress by increasing deposition of mineral salts and collagen fibers.
• Without mechanical stress, bones undergo demineralization (loss of bone minerals) and collagen reduction.
• Therefore, exercises that place physical stress or load on the skeletal system stimulate osteoblast activity, increasing bone density.

Evaluate the exercise options

• High impact: Activities like jumping or running apply rapid, high-magnitude forces to bones, which strongly stimulates bone deposition. (Correct)
• Density depleting: This is not a standard exercise type and implies losing bone density, which is harmful to bone health. (Incorrect)
• Strength-training: Resistance exercises (e.g., lifting weights) pull on the bones via muscle contraction, promoting localized bone growth and strength. (Correct)
• Weight-bearing: Exercises where you work against gravity while staying upright (e.g., walking, hiking) force the bones to support body weight, stimulating bone maintenance. (Correct)
