Exercise is an important part of the overall strategy for improving the health of your bones. The optimal exercise regimen for preventing osteoporosis has yet to be established, but these guidelines are based on our current state of knowledge. We do know that exercise works best when you have adequate levels of estrogen, calcium intake and vitamin D.
Even though we think of bones as solid, rocklike structures, they’re actually a living tissue that is constantly changing. Peak bone mass usually occurs by the age of 25 and then slowly declines. Bone loss accelerates during the first several years following menopause. The foods we eat, the amount of physical activity we perform and various lifestyle and genetic factors contribute to bone health.
If you have been diagnosed with osteoporosis or osteopenia, check with your physician before starting any exercise program.
How we work, play, sit and move can determine the stress placed on our spine. Viewed from the side, the spine is shaped like an S-curve. It is ten times stronger when these natural curves are maintained. Good posture and body mechanics can alleviate/prevent back pain and protect your spine against fracture.
Moving & Lifting
It requires lots of practice before new ways of performing daily tasks become a habit. But the payoff is long-term back health. Start off with a few changes. Make an effort to be aware of your movements and protect the spine.
Much of our day is spent sitting or bending. This can tighten some muscles and put stress on the spine. As part of an overall program of stretching, develop good flexibility in your back, hamstrings (back thigh), hip flexors (front thigh) and pectoral (chest) muscles. Avoid forward bending exercises which can put stress on the bones and discs of the spine. Stretch the muscles to a point of tension, not pain, and hold the stretch for 15-30 seconds at least 3 -5 times daily or as directed by your physical therapist.
Strength training is probably one of the most important things you can do to build or maintain strong bones. To get the best results, you should consider
Each time we step, jump, run or balance on part of our body, the impact causes compressive force on the bone, which encourages bone building. That’s why it’s important to participate in regular weight-bearing exercise that is appropriate for your fitness level and current bone health. For example: very fast walking, uphill walking, stair-stepping, jump rope or jumping activities, high-impact aerobics, jogging, dancing, soccer, tennis, squash and basketball can all be good exercise choices for bone-building. High impact forces and a variety of movement patterns cause a stronger bone response. However, your strength, heart health and bone integrity must be adequate for safe exercise. Your doctor or physical therapist can tell you what’s safe and effective for you.
Strength training exercises done standing (or when balancing your weight on a leg or hand) are also an important part of a weightbearing exercise program.
Good levels of strength and flexibility guarantee that you’ll keep your balance more easily. To help prevent falls, activities that require balance are also good to practice. Many forms of dance, yoga and martial arts training (including tai chi) can promote good balance.
A simple exercise: Practice standing on one foot for 30 seconds. Repeat with the other leg. When you can do this easily, try it with your eyes closed or while moving the "air leg" forward-and-back or out-and-in. There are all kinds of balance games and activities you can do. Just remember to progress gradually and provide for something to grab if you need a balance check.
As an adolescent or young adult, exercise can boost your bone mass. After the mid-thirties, success means keeping the bone you have (or slowing the rate of bone loss). Whatever your age, exercise is good medicine for your body and your bones.
