In this Chapter, we discuss the evidence for physical activity interventions conducted across a range of older people, including the chronologically ‘old-old’, frail older people, those with disabilities and those with one or more of the health conditions covered by the National Health Priority Areas.
The WHO Heidelberg guidelines (1997) identify three groups of older people along the health-fitness gradient:
- the physically fit-healthy
- the physically unfit-unhealthy but independent living and
- the physically unfit- unhealthy and dependent individuals.
- the physically unfit yet currently healthy.
