Latest Research into Specific Strength Training for Osteoporosis


weight bearing exercise older adults

Osteoporosis Australia and ESSA have issued a joint position statement stating that : Bones need to be ‘stressed’ in very specific ways in order to get stronger. There is now good quality evidence that weight bearing impact exercises, such as hopping and jumping, and progressive resistance training (PRT), such as lifting weights in the gym, are the most effective exercises for improving and preserving bone strength throughout life.

Experts have generally been very cautious with exercise advice for people with osteoporosis, but there is growing evidence for the benefits of quite intensive resistance exercise in this group. However, it’s absolutely crucial that these exercises are performed under strict supervision by a qualified exercise professional’.

The best example of scientific evidence, for a highly specific exercise program for Osteoporosis was seen in the ‘Osteo-cise’ study in Melbourne. (Daly, 2014). The study ran over 12 months, implementing exercise programs out of local gym facilities for patients diagnosed with Osteoporosis. There were 3 main components of the exercise program which contributed to its success

  • High velocity, power resistance training (fast concentric, slower eccentric)

  • Highly challenging balance exercises

  • Moderate impact exercise – chosen individually

The average percentage improvement in bone in this study was 1.5% in the Lumbar spines. Other studies looking at combined strength and impact exercise have shown similar improvements of percentages of up to 3.8%. Interestingly too, studies where patients just walked showed no improvement in bone density.

The percentage improvement of bone density with exercise should be taken into context, for example, during menopause, females can be losing 2-3% of bone density per year and around 1% per year following menopause (Watkins, 2010). A common medication used for osteoporosis, Fosamax, has reported improvements of 4-8% in the spine and 1-3% in the hip (Osteoporosis Australia). From the studies reviewed we have seen strength exercise to have similar percentage improvements, without the side effects of medication and added benefit of muscle retention and growth.
