Physical Activity and Bone Mass

 The Facts:
a. The authors were interested in the effect of physical activity on bone mineral density in young adults.

b. They reviewed the existing literature and selected 19 manuscripts for inclusion in their review.
  
C. The included studies did not show a consensus but did seem to indicate that participation in sports during the periods of growth and during young adulthood promoted bone density.

e. The authors felt that “promoting vigorous-intensity activity especially” for females was important to reduce osteoporosis risks.

 Dr. Lane: It appears that the time to start thinking about osteoporosis is years before it becomes a crisis. We‘ve all heard that you have to use it or lose it but in this case it appears that you have to use it to even get it in the first place.
