Muscle loss slows down the elderly
÷ Elderly people walk at a slower speed and tire more quickly because of loss of strength and mass in leg muscles, according to a study. ÷ Using computer simulations they found that these physiological changes explain the slower walking speed preferred by the elderly, and that a focus on building up these leg muscles may be the only effectivewayto improve elderly walking. ÷ The Journal of Physiology research pointed out that a decline in walking performance can lead to a less active lifestyle, worsening the health of elderly people, and is directly linked to a lower 10year survival rate for people at age 75. ÷ The findings of this study suggest that a focus on building up muscles in the legs may be the only effective way to improve elderly walking. In other words, improving other features such as joint flexibility or walking strategy would not help normal elderly people to walk better.
