Osteoporosis is a loss of bone mineral density that causes bones to become brittle and highly susceptible to fracture – particularly in the hip, spine and wrists. No matter what your age, bone needs physical activity, just like muscle, to retain strength and post-menopausal women can expect to lose around 1% of their bone mineral density each year. Currently 1 in 2 adults over 50 are inactive, that is they participate in fewer than 30 minutes of exercise per week.
Other modifiable lifestyle factors that can affect bone density are:
- excessive alcohol intake
- poor nutrition
- low calcium intake
There are no warning signs of osteoporosis. The disease is silent and painless until a fracture has occurred.
Exercise works for osteoporosis prevention because it places stress on bones, which results in increased bone mass. For post-menopausal woman the most effective exercise to strengthen bones is high impact exercise. A well balanced exercise programme including weight-bearing, impact exercises and strength training should be designed for an individual hoping to prevent or minimise the deterioration of osteoporosis.
Weight bearing high impact exercises could include:
- stair climbing
If you are not able to do high impact exercises then you could consider:
- elliptical training machines
- low impact aerobics
- stair-step machines
- walking (treadmill/outside)
Strength training should have a whole body approach as adaptations in bone mineral density are site specific. Strength training exercises include activities such as:
- Functional movements, such as standing and rising up on your toes
- Lifting weights
- Using elastic exercise bands/dynabands
- Using weight machines
- Lifting your own body weight, such as push-ups.
If you would like to reduce your risk of osteoporosis, increase your bone density and slow or reverse the normal bone loss associated with ageing, a good place to start would be my blog on Resistance exercises using body weight.
