Exercise puts the lungs under greater pressure to perform. More alveoli are involved in the
process of gaseous exchange and their ability to perform this task rapidly and efficiently
is improved. Continued smoking and prolonged exposure to air pollution can significantly
reduce the ability of the alveoli to accomplish this exchange and diminish the capacity of
whole sections of lungs to function. Fortunately, exercise, running in particular, can help
reverse this process and over time enable the tissue to regain its functional ability (unless
the smoking and air pollution have destroyed the walls of the alveoli themselves, as in
emphysema).
Pumping Iron for the Long Haul Although it seems that resistance training would improve endurance performance, that's not always the case. Strength has to be converted into sport-specific movement and power. However, resistance training is important for reducing injuries and slowing the muscle mass losses associated with aging.
