Abstract in brief

  • The LIFE study found that increasing physical activity levels in older adults with mobility limitations leads to better physical functioning and reduces the risk of developing major mobility disability.
  • The study showed a dose-dependent relationship, meaning the more physical activity participants engaged in, the greater the improvements in gait speed, physical performance scores, and disability prevention.
  • Even small increases in weekly physical activity, around 48 minutes, were associated with meaningful benefits, emphasizing the importance of moderate activity for maintaining mobility in older adults.]
