Question: Osteopenia- tread mill excercise


 rajivb - Tue Nov 03, 2009 10:25 am

I am a 60 years old female diagnosed last year with Osteopenia; my BMD readings in last one year have shown deterioration in AP Spine (old reading -1.4, new -2.0) and Right Fore arm (old -1.7, new- 2.4) and no change in Left Femur -1.8.
What excercises will benefit me?
Will 30 minutes walking on Tread Mill at 4 to 5 km per hour speed be helpful or this is not recommended.Please advise.
I have recently started Fosavance 70 mg once a week.

User avatar Hi,
It is well known that exercises have beneficial effects on bones. Human as well as animal studies have shown that exercises do increase bone mineral density (BMD), as well as bone mass and strength . In addition, exercise has been shown to protect against age-related bone loss.It is thought that the mechanical stresses generated by exercises play a crucial role in the osteogenic response. Human studies have investigated osteogenic responses to exercise in many types of training programs, such as running and walking, resistance training, aerobic exercise, and high-impact or jump exercise etc.

Most animal studies have investigated treadmill running and found beneficial effects on bone in induced osteopenia.Some isolated reports have noted that high-impact, low-repetition jump exercise has an osteogenic effect on lower limbs in middle-aged osteopenic rats.One must be careful in extrapolating these results in animal experiments to a human situation.

Weight-bearing exercises are those where one's muscles are working against gravity. These can be divided into low-impact and high-impact exercises.Low-impact weight-bearing exercises are advisable if one is already diagnosed with osteopenia and is at risk for fall or fracture. In low-impact, weight-bearing exercise, one should not jump or twist. Usually, one foot must always be on the ground.

Treadmills and stair-climbing machines provide low-impact weight-bearing benefit.Treadmills are OK as long as the speed is such that one does not start to run(in which case, it becomes a high impact exercise).Therefore, it is advisable to do treadmill exercises under supervision rather than to experiment with the speed settings. The other safer option is to join a low-impact aerobics class or go for a careful,brisk walk.

Best wishes!
