Osteoporosis Research Studies
Context: Osteoporosis affects approximately 200 million people worldwide and approximately 14 million people in the United States. A decrease in estrogen levels in post-menopausal women puts them at a higher risk for osteoporosis and consequently leaves them at a higher risk for bone fractures. Certain types of physical activities and exercises have been shown to slow the effects of osteoporosis.
Objective: The authors goal was to use previously conducted studies to determine which types of exercises and prescriptions were most effective in minimizing the negative effects of osteoporosis in post-menopausal women.
Design: The authors conducted a literature search using several keywords such as post-menopausal osteoporosis, aerobic training, …show more content…
Main Outcome Measure(s): In order to determine the effectiveness of the various interventions the authors primarily looked at how the interventions affected the subjects bone mineral density (BMD). Other measurements utilized were lab results looking for bone formation markers, bone resorption marker, and urine resorption marker.
Results: A study reviewed looked at BMD in 44 elderly runners compared to generally sedentary subjects of similar age. The runners had a 2% increase in lumbar spine BMD and a 6.8% increase in femoral head BMD over the sedentary subjects.1 A randomized controlled trial that looked at power versus strength training in an elderly population. After the subjects went through two years of the intervention the power-training group maintain lumbar spine BMD while the strength-training group saw an average decrease of 2.4% in lumbar spine BMD.1 In a study that examined balance and proprioceptive exercises in post-menopausal women that did a program that included balance and proprioceptive exercises had a 38% decrease in the incidence of falling.1 In a study that examined the effectiveness of low frequency vibration on osteoporosis a group that received vibration treatments saw a 4.3% increased BMD in the femoral neck over a group that walked 3 times per
