Question

select the correct answer. how does participating in an impact exercise such as jumping rope affect you? a. it decreases your chance of injury. b. it increases your contraction rate. c. it decreases your flexibility. d. it increases your bone density.

Explanation:

• Option A: Impact exercises like jumping rope may increase injury risk if not done properly, so A is incorrect.
• Option B: Contraction rate (of muscles) isn't directly increased by jumping rope in a typical way related to impact exercise benefits, so B is incorrect.
• Option C: Jumping rope can improve flexibility or at least not decrease it; impact exercises don't inherently reduce flexibility, so C is incorrect.
• Option D: Impact exercises put stress on bones, which stimulates bone growth and increases bone density. This is a known effect of weight - bearing/impact exercises.

Answer:

D. It increases your bone density.
