Lifelong endurance training significantly enhances cardiovascular capacity and left ventricular function in elderly men. Veteran athletes maintained superior physical function compared to sedentary peers, highlighting the benefits of sustained physical activity.

Area of Science:

  • Cardiology
  • Exercise Physiology
  • Gerontology

Background:

  • Aging is associated with declines in cardiovascular capacity and left ventricular function.
  • Lifelong physical activity may mitigate age-related cardiovascular changes.

Purpose of the Study:

  • To investigate the long-term effects of endurance training on cardiovascular function in elderly men.
  • To compare cardiovascular capacity, left ventricular function, and myocardial perfusion between veteran athletes and sedentary controls.

Main Methods:

  • Studied 10 healthy elderly male endurance athletes (73 ± 3 years) and 12 sedentary controls (75 ± 2 years).
  • Utilized echocardiography, exercise stress tests, gated blood pool scans, and myocardial perfusion scintigraphy.
  • Measured maximal oxygen uptake (VO2 max).

Main Results:

  • Veteran athletes exhibited significantly higher maximal VO2 (41 vs. 26 mL.kg-1.min-1, P < 0.001).
  • Athletes showed superior resting systolic and diastolic left ventricular function and higher exercise ejection fraction (P = 0.003).
  • Myocardial perfusion defects were observed in 70% of athletes, but none of the controls.

Conclusions:

  • Endurance training enables maintenance of high physical capacity into old age.
  • Superior cardiovascular function in veteran athletes is attributed to enhanced left ventricular systolic and diastolic function.
  • Myocardial perfusion defects in veteran athletes require careful interpretation due to their prevalence.
