Exercise in Old Age Strengthens Your Immunity and Heart

Notably, T-cell activity was not only higher in active versus inactive older adults, but the very active cyclists were also producing a level of T-cells common among young adults in their 20s. According to Science Daily, these findings are significant to adults in the U.K., in part, because:5

  • Less than half of adults over age 65 get enough exercise to stay healthy
  • More than half of adults aged 65 or older suffer from at least two chronic diseases

“[The study] really tells us that staying physically active all of your adult life can prevent much of what we think of as aging, including immune aging,” said study author and professor Janet Lord, director of the Institute of Inflammation and Aging at the U.K.’s University of Birmingham.6 She added:7

 “The immune system declines by about 2 to 3 percent a year from our 20s, which is why older people are more susceptible to infections, conditions like rheumatoid arthritis and, potentially, cancer. Because the cyclists have the immune system of a 20-year-old rather than a 70- or 80-year-old, it means they have added protection against all these issues.”

Professor Emeritus Norman Lazarus, 82, of the Center of Human and Aerospace Physiological Sciences at King’s College London, who was a study participant and coauthor of the research, said, “If exercise was a pill, everyone would be taking it.” Professor of human and applied physiology and Center director Steve Harridge stated, “Being sedentary goes against evolution because humans are designed to be physically active.”8
