Questions and Answers

What are some benefits of exercise mentioned in the text?

  • Promotes clinical depression and accelerates some forms of dementia
  • Expands peripheral blood circulation, increases cardiac output, and improves vascular elasticity (correct)
  • Reduces peripheral blood circulation, decreases cardiac output, and worsens vascular elasticity
  • Stimulates bone loss and accelerates osteoporosis

What do the mechanisms underlying the benefits of exercise do?

  • Drive healthy adaptations and antagonize the inflammation and metabolic consequences of atrophy and aging (correct)
  • Suppress healthy adaptations and promote inflammation and metabolic consequences of atrophy and aging
  • Have no impact on the inflammation and metabolic consequences of atrophy and aging
  • Exacerbate inflammation and metabolic consequences of atrophy and aging

What does exercise increase the expression of?

  • Genes promoting inflammation and metabolic consequences
  • Key adaptive genes (correct)
  • Genes associated with atrophy and aging
  • Genes related to sedentary lifestyle
