WHO Recommends Exercise Regimens to Protect Senior Brain Health

The World Health Organization and the United Nations define the onset of aging at about 60‑65 years, a period often linked to retirement and declining muscular, cognitive and functional abilities. Scientific evidence shows that around age 66 the brain’s network topology changes, making physical activity a crucial tool for preserving cognition.

The NeuronUP platform explains the FITT model (Frequency, Intensity, Time, Type) for senior exercise: any activity beats sedentarity; moderate‑to‑vigorous intensity triggers neurotrophic factors like BDNF; 70‑140 minutes of moderate or 35‑75 minutes of vigorous exercise weekly are sufficient for measurable cognitive benefits; and a mix of aerobic, strength, and coordination‑balance activities (e.g., walking, cycling, resistance training, dancing) targets different brain mechanisms.

Separately, sociologist Serge Guérin notes that the social perception of “old age” has shifted upward, now closer to 70 rather than 60, with no fixed age threshold. He highlights that while medical risk of loss of independence rises after 85, workplace bias can begin at 45 and intensify after 55. The combined insights stress the importance of both active lifestyles and evolving social attitudes for healthy aging.
