Walking habits and health-related factors in a 70-year-old population.

Walking and other physical activities were studied in a representative population sample of 619 70-year-old people in the city of Gothenburg, Sweden. Walking was the most common physical activity declared, and two thirds of those without an obvious disability walked 30 min or more every day. Subjects who took a daily walk of at least 30 min had a significantly better climbing capacity, higher bone mineral content and lower concentration of blood triglycerides than subjects who walked less. Male 'walkers' had a significantly larger lung volume than 'non-walkers'. Walkers had a more positive attitude towards physical activity as well as a higher estimation of their own physical fitness than non-walkers.
