Comparison of Bone Mineral Density in Lumbar Spine between Athletic and Non-Athletic Premenopausal Women

Background & Aims: The purpose of the present research was to compare the bone mineral density (BMD) of lumbar spine between athletic and non-athletic premenopausal women. Methods: Fifteen female athletes (runner) with the mean age of ۳۳.۸۰ ± ۴.۸۱ years, mean height of ۱۶۴.۱۳ ± ۵.۳۱ cm, mean weight of ۵۷.۳۳ ± ۴.۲۲ kg, and mean body mass index (BMI) of ۲۱.۴۱ ± ۲.۲۱ kg/m۲ and ۱۵ female non-athletes with yhe mean age of ۳۶.۷۳ ± ۵.۰۲ years, mean height of ۱۶۱.۲۰ ± ۴.۱۷ cm, mean weight of ۶۸.۰۰ ± ۱۰.۶۷ kg, and mean BMI of ۲۶.۷۸ ± ۴.۳۴ kg/m۲ at the premenopausal age (۳۰-۴۵ years) were participated. The BMD of lumbar spines were measured by dual-energy X-ray absorptiometry (DEXA). The collected data were analyzed through t-test statistical methods. Results: Based on T-score and Z-score criteria, all of athletes had normal bone tissue while, ۱۳.۳ percent of non-athletes were osteopenic. Moreover, the BMD of lumbar in athletes was significantly more than nonathletes. Furthermore, in the lumbar spine region, significant differences observed between the T-score and Z-score values for both athletes and non athletes. Conclusion: It seems likely that running can increase the BMD of lumbar in premenopausal women; therefore, it can play an important role in preventing osteoporosis as an effective non-medicine method.
