Question

select the correct answer.

how does resistance training prevent osteoporosis?

it lowers the cholesterol levels in your blood, which causes your bones to become strong.
it reduces your blood pressure, causing your bone density to increase.
it increases bone mass, making your bones stronger and denser.
it makes you feel hungry so you eat more calcium, which strengthens your bones.

Explanation:

Analyze the physiological mechanism of resistance training on bone health

Resistance training (weight-bearing exercise) places mechanical stress on bones. This mechanical loading stimulates osteoblasts (bone-building cells) to lay down new bone tissue, which increases bone mineral density and overall bone mass.

Evaluate the given options

• Option 1: Cholesterol levels do not directly regulate bone strength or bone mineral density.
• Option 2: Blood pressure reduction is beneficial for cardiovascular health, but it does not drive bone density increases.
• Option 3: Resistance training directly increases bone mass, making bones stronger, denser, and less prone to fractures, which directly prevents osteoporosis.
• Option 4: Feeling hungry and consuming calcium is an indirect, non-scientific explanation; resistance training physically stimulates bone remodeling directly.

Answer:

• It lowers the cholesterol levels in your blood, which causes your bones to become strong.
• It reduces your blood pressure, causing your bone density to increase.
• It increases bone mass, making your bones stronger and denser. (Correct answer)
• It makes you feel hungry so you eat more calcium, which strengthens your bones.
