Abstract

Swim records data from the U.S. Masters swim program afforded a chance to estimate the decline in swim performance over middle life. Men's records data indicated a falloff in swim performance of slightly less than one percent per year over the ages of 27.5 to 57.5 years. Men's decline in freestyle performance was seen to be essentially the same, regardless of varying oxygen requirements secondary to the distance swum. Men's decline in swim performance for the breaststroke and backstroke events was nearly that of the freestyle. Falloff in men's performance in the butterfly stroke rose to 1.47 percent per year. Women's times showed a decline between 20 to 50 percent greater than that seen for the men. Previous findings of athletes' decrease in pulmonary function over middle age closely parallel the observed decrease in Masters swimmers' records--approximately one percent per year.
