Why the study?
Does regular physical exercise improve microcirculatory function and nitric oxide availability in older and young men compared to a sedentary lifestyle?

84 men, including 39 male athletes (age range 22-72 years) and 45 age- and sex-matched sedentary controls
Comparison
Regular physical exercise (athlete status) vs Sedentary lifestyle (untrained controls)

Does regular physical exercise improve microcirculatory function and nitric oxide availability in older and young men compared to a sedentary lifestyle?
Regular physical exercise is associated with improved endothelial function and increased nitric oxide availability in both young and older men, counteracting age-related microcirculatory impairment.
