High-impact workouts can benefit seniors' bone mass
By Gina Garippo, Pure Matters
A study published in the journal Sports Health: A Multidisciplinary Approach analyzed the bone density of 560 athletes, ages 47 to 93, who competed in the Senior Olympic Games. They found that men and women who played high-impact sports had much higher bone density than those who participated in low-impact games. High-impact activities include those that require almost continual running and jumping -- such as track and field, road racing, and basketball.
A Big Impact on Bone Density
The difference in bone density measurements between adults playing high- and low-impact sports was significant. Playing a high-impact sport improved bone density scores by 3 percent. That's about the same percentage of decline caused by some individual risk factors, such as age.
Not everyone can participate in high-impact activities. It may be better for people with osteoarthritis and other chronic health problems to stick with low-impact activities. Thankfully, any weight-bearing exercise -- including lower-intensity activities like walking -- can help ward off bone loss. However, the study shows that for older adults who are able, exercising at a higher intensity may provide additional bone benefits.
Even Small Amounts of Activity Help
You don't have to be an Olympic athlete to reap the benefits of high-impact activity. Add a little jogging to your daily walk or join a high-impact aerobics class. Just be sure to talk with your doctor before starting or changing an exercise program.
