October 20 was World Osteoporosis Day. I blogged about osteoporosis several years ago, but here is a quick refresher. It is a condition that weakens the bones and makes them more susceptible to injury and breakage. Although it mostly affects women, osteoporosis can happen to men, as well.
In my previous blog, I discussed the importance of weight training for those with this condition. As always, caution should be used in any exercise program and it is best to consult a medical professional before beginning. Although we have been accustomed to hearing that older people should not work with weights because they might hurt themselves or break a bone (which can happen), the opposite is the case with osteoporotic individuals. Putting controlled stress on the bones makes the stronger; working with weights does not just build muscle alone.
What are the best exercises to do for those with osteoporosis?
According to the Cleveland Clinic, cardio exercises (that help to build heart and lung capacity) should have a weight-bearing element to them. Swimming and biking are not weight-bearing, so while they are good for the body, they will not strengthen bones. Walking, running and dancing are examples of exercises that will affect the bone structure.
As for resistance training (using weights), the Cleveland Clinic suggests focusing on the parts of the body that are most likely to suffer a fracture: spine, hips, and wrists. As we age, many of us use lighter weights and do more reps (repetitions of the movement), but with osteoporosis there must be enough weight/resistance to cause the bone to respond; this requires using heavier weights and doing fewer reps. It is important to work with a fitness or PT professional to determine the right weight, exercises and number of reps to be most effective. Certain stretches are also important: back extensions, shoulder shrugs and rolls, knee raises and ankle flexes, so that the toes come up toward the knees.
There are elements of diet and medications that can improve the condition, but certainly exercise is an important aspect of managing osteoporosis. Even after World Osteoporosis Day, we raise awareness of the condition, the ways it can be treated, and the importance of continued research that will allow older adults to live longer, stronger and healthier lives.
