ABSTRACT

Background: Appropriately designed and controlled physical activity by means of aerobic, weight-lifting and motor-coordination exercises has an impact in the bone quality.
Objective: The aim is to observe the effect of the physical activity on the bone mineral density (BMD) in Mexican women between 45 and 60 years of age.
Material and Method: A prospective, longitudinal, descriptive study in forty seven sedentary women (17 premenopausal and 30 menopausal), between 45 to 60 years of age, recruited for a ten-month physical program. Bone mineral density and speed of sound (SOS) were measured using a quantitative ultrasound of the tibia and radius at the beginning and at the end of the physical program.
Results: There were significant differences in physical condition before and after the program. Bone mineral density showed no significant change. There was an increment in SOS—in radius from 3085,21 to 3999 m s-1, and in tibia from 28,74 to 3801,7 m s-1 (p‹ 0.02)—in both groups.
Conclusions: Controlled physical activity can maintain bone quality in menopausal women. Quantitative ultrasound allows monitoring of changes in bone microarchitecture and so lowers the cost of related studies.
