Osteoporosis is common in Australia. Roughly 3.8% of the population were diagnosed with Osteoporosis, which is roughly 924,000 Australians. It’s a condition where the bones become fragile, weak and brittle, leading to a high risk of fractures from minor bumps or accidents.


WHAT IS OSTEOPOROSIS?

Osteoporosis is a skeletal disorder characterised by compromised or weakened bone strength, leading to an increased risk of fracture.

Bone mineral density (BMD) plays a role in indicating the presence of Osteoporosis. According to the World Health Organization (WHO) a BMD T-score between -1.0 and -2.5 below the young adult average is classified as Osteopenia, meaning low bone mass, while a score -2.5 or more below indicates the presence of Osteoporosis.

Decreased bone mineral density occurs when bones lose minerals more quickly than the body can replace them.


RISK FACTORS FOR OSTEOPOROSIS

There are some risk factors for Osteoporosis we can change, and some we cannot. Here are some common ones: ● Sedentary lifestyle ● Ageing resulting in reduced testosterone and oestrogen levels ● Menopause ● Previous fracture ● Excessive alcohol consumption ● Previous or current smoker ● Insufficient Calcium and Vitamin D intake ● Androgen-deprivation therapy treatment for prostate cancer ● Medications such as Thiazides (anti-diabetic medication) and Glucocorticoids (asthma medication) ● Chronic Kidney Disease, including those receiving dialysis treatment


TYPES OF EXERCISE THAT ARE OSTEOGENIC AND REDUCED FRACTURE RISK

Exercise that is bone building (osteogenic), is very important from early childhood to early adulthood as it provides stimulus to lay down a solid foundation. As we age, we naturally lose bone due to the ageing process.

Exercise has been scientifically proven to help in the treatment and management of Osteoporosis by slowing the decline or increasing bone strength.

The bone remodeling process takes approximately 9-12 months to occur, which means in order to see improvements in bone strength, exercise should be maintained for at least a few months.


THERE ARE 3 MAIN EXERCISE TYPES COMMONLY USED TO TREAT OSTEOPOROSIS:
1. PROGRESSIVE RESISTANCE TRAINING (PRT)

PRT is the most effective strategy to improve skeletal muscle mass, size and strength, and thus should form the basis of any exercise programs designed to reduce fracture risk. Recommendations suggest that 2 days per week, 2-3 sets of 8 repetitions of approximately 8 exercises per session should be included, targeting major muscle groups that attach around the hip and spinal regions, which are the most common sites of Osteoporosis. It’s encouraged to perform PRT for a few weeks prior to commencing impact exercise to develop a baseline level of strength.

2. IMPACT LOADING

Impact Loading is a form of osteogenic exercise, consisting of movements that expose bone to load and stimulate bone growth in fast, novel and multidirectional ways. The difficulty may be increased by varying the exercise, direction, height of different jumps or adding weighted vests. Here are some exercise examples: ● Moderate impact activities: running, stride jumps, jump rope, side steps, highland-type dancing, jump take offs and hops ● High impact activities: landings from jumps (high vertical jumps, star jumps, tuck jumps, and drop landings


Considerations: If you don’t have low bone mineral density (nil Osteopenia or Osteoporosis), you may perform high-impact activities. If you have Osteopenia, you may perform moderate-high impact activities. If you have Osteoporosis, you may perform moderate impact activities only.





3. BALANCE TRAINING

Our balance declines due to the natural ageing process, but it is possible to slow the decline in function or even improve their integration. Exercises should incorporate both static and dynamic balance that aims to reduce the risk of falling and ultimately, the risk of fracture and associated disability.

Guidelines suggest balance training should be performed 4 times per week for approximately 30 minutes before or after PRT or impact loading sessions, be challenging and preferably specific to everyday tasks you may perform. These exercises may be progressed by reducing base of support, adding external perturbations, dual tasking and modifying surfaces (just to name a few). Aim to complete the exercise without holding on; if you need to hold onto something before achieving the desired time, the exercise may be too difficult.

Considerations: Ensure you have something to hold onto nearby if required.
