Contribution of Structured Exercise Class Participation and Informal Walking for Exercise to Daily Physical Activity in Community-Dwelling Older Adults.

Examined the physical activity and exercise habits of independent-living older adults from a structured exercise program, noting the contribution of formal and informal exercise participation relative to total daily physical activity measured using pedometer and daily activity logs. Participation in structured exercise was an important contributor to total physical activity and the only source of resistance and flexibility training, despite frequent walking for exercise outside of class.
