Swim performance decrement over middle life.

R H Rahe, R J Arthur

    Medicine and Science in Sports
    |January 1, 1975

    Summary

    Masters swimmers experience a performance decline of about 1% annually in middle age. Women swimmers show a greater performance decrease than men, with butterfly stroke decline being the steepest for men.

    Area of Science:

    • Sports Science
    • Gerontology
    • Human Performance

    Background:

    • Middle age is associated with physiological changes impacting athletic performance.
    • Understanding age-related performance decline in swimmers is crucial for training and health.
    • Previous studies suggest a link between declining pulmonary function and reduced athletic capacity in aging athletes.

    Purpose of the Study:

    • To estimate the rate of swim performance decline in middle-aged athletes using U.S. Masters swimming data.
    • To compare performance decline across different swimming strokes (freestyle, breaststroke, backstroke, butterfly).
    • To analyze sex-based differences in age-related swim performance decline.

    Main Methods:

    • Analysis of U.S. Masters swim records data spanning middle age.
    • Calculation of annual percentage decline in performance for male and female swimmers.
    • Comparison of decline rates across various swimming strokes.

    Main Results:

    • Men's swim performance declined by approximately 1% per year between ages 27.5 and 57.5.
    • Freestyle, breaststroke, and backstroke performance declines were similar for men; butterfly showed a higher decline (1.47% per year).
    • Women's swim performance declined 20-50% more than men's.

    Conclusions:

    • Swim performance decreases steadily throughout middle age, aligning with general trends in athletic decline.
    • The rate of decline is stroke-dependent, with butterfly showing the most significant drop in men.
    • Women experience a more pronounced performance reduction compared to men in Masters swimming.
