A study examining the effects of smoking cessation found some fitness improvements after a week. Eleven young men who smoked about a pack a day for 31/2 years were subjected to several tests while on a stationary bike before quitting, and then a week later. The 2000 study, published in Medicine & Science in Sports & Exercise, showed that pulmonary functions showed no significant improvement, but oxygen concentration considerably increased, and exercise time was greatly extended.
