Regular physical activity, especially strength training, is key for older adults to maintain muscle performance and mobility, reducing fall risks. Trophic factors lack sufficient evidence for long-term use.

Area of Science:

  • Gerontology
  • Exercise Physiology
  • Muscle Biology

Background:

  • Age-related strength loss impairs mobility and increases fall risk.
  • Physical activity and trophic factors are explored for prevention.
  • Epidemiologic data supports physical activity for successful aging.

Purpose of the Study:

  • To review evidence on interventions preventing age-related strength loss.
  • To assess the efficacy of exercise and trophic factors.
  • To identify areas for future research.

Main Methods:

  • Review of epidemiologic evidence and randomized controlled trials.
  • Analysis of exercise interventions (endurance, strength, balance).
  • Consideration of trophic factors and psychoactive drug effects.

Main Results:

  • Strength and endurance training improve muscle performance in older adults.
  • Exercise interventions promote mobility and reduce fall risk, with variations by program and group.
  • Insufficient evidence supports long-term trophic factor use.
  • Psychoactive drugs may increase inactivity and affect muscle performance.

Conclusions:

  • Strength training is a recommended strategy for older adults, particularly the weak.
  • Further research is needed on strength training's benefits in chronic illnesses.
  • Avoiding certain psychoactive drugs warrants investigation.
