Osteoporosis is a condition affecting bone density. Bones are mostly made up of collagen, a protein that provides the flexible framework of bone, and minerals such as calcium phosphate and calcium carbonate that provide rigidity and strength to the framework.
Bone cells are constantly changing and adapting to their environment, with bones responding to the demands and stresses placed on them. If you do not use your muscles and bones they will become weaker, but if you stay active and use your muscles then bones become stronger due to imposed demands.
Osteoporosis develops when bones lose minerals faster than the body replaces them, meaning the bones decrease in mass and density. Overtime the bones become more fragile and brittle. Osteoporosis is often called a “silent” disease as the bone loss stays hidden until you see the effects, eg. a fracture, Dowagers hump, loss of height. The most common bones affected are the hip, spine, wrist, ribs, pelvis and upper arm. Osteopenia is the definition of having lower than normal bone density and is one stage before osteoporosis.
The greatest amount of bone is built during childhood and adolescence. By age 18 in girls and 20 in boys, nearly 90 percent of “peak bone mass” is reached. However the amount of bone tissue can keep increasing until around age 30. Once “peak bone mass” is reached we start to lose bone density (as well as muscle strength) each year as we age. It is therefore important to build as much bone mass as possible early on in life.
Risk factors for developing osteoporosis include: a family history, Caucasian/Asian females, being older than 60 years, medical history, lifestyle (such as low levels of exercise, smoking, high alcohol intake, being underweight), low calcium and low vitamin D levels.
To reduce the risk of developing osteopenia or osteoporosis it is recommended that you eat a healthy diet with adequate calcium, get sufficient vitamin D, quit smoking, reduce alcohol and coffee intake, and undertake regular exercise. Activities shown to specifically improve bone density include weight bearing activities and strength training.
If done correctly Pilates offers a great platform for strengthening bones and preventing fractures.
Pilates exercises can:
• increase bone density
• increase muscle strength and mass, allowing the body to support the bones weakened by osteoporosis
• improve coordination and balance which can help to prevent falls
• improve flexibility and posture and help reverse some of the postural changes as a result osteoporosis.
Before prescribing Pilates exercise it is important to distinguish between those people that have osteoporosis, osteopenia and those with normal bone density.
For those people that do not have osteoporosis the aim is to increase bone density and prevent bone loss. Weight bearing exercises need to have an effect on the bone, be regular and need to be moderate to vigorous in intensity e.g. jogging, jumping, stair climbing, walking up hills, tennis, aerobics. Strength training exercises can include hand weights, resistance bands, machine weights, body weight. Machine and mat Pilates are perfect ways to achieve these aims.
A diagnosis of osteoporosis requires a great deal more care and consideration when designing a Pilates program. People with osteoporosis require an individual program as there is a higher risk of fractures due to falls or inappropriate exercising. High intensity exercises are not recommended, the aim is to maintain bone strength and reduce the risk of falls and fractures by improving posture, balance and muscle strength. Exercises to be avoided are those that place strain on the spine including trunk flexion (bending forward or sit ups), twisting movements and high impact exercises. Good exercises include those that work the back, shoulders, legs and hips, areas that commonly lose density the most and result in more debilitating fractures.
So if you are looking at preventing a loss of bone density, improving your muscle strength and bone density, or have a diagnosis of osteoporosis please see one the Physiotherapists at QPilates. We are well qualified to assess you and provide an individualised program to ensure you are performing appropriate exercises for your condition.
