Abstract: Objective To explore the effects of estrogen,sport walking with weight and estrogen plus sport walk on serum lipid,bone metabolism and bone mineral density(BMD) in postmenopausal women.Methods 52 postmenopausal women were divided into the hormone replacement therapy(HRT) group(n=12),sport walking with weight group(Sp group,n=14),HRT + Sp group(n=12) and control group(n=14).HRT group took compound nylestriol,Sp group took sport walking with 5 kg weight and exercise intensity was from 60% to 80% VO2max,HRT+Sp group received two treatments as HRT group and Sp group.The experimental duration consisted of six months.Results The total cholesterol(TC),TC/high density lipoprotein cholesterol(HDL-C),alkaline phosphatase(APL) and urine calcium(Ca)/creatinine(Cr) were markedly lower in three experimental groups than the control group and before experiment(P<0.05 or P<0.01),HDL-C in Sp and HRT+Sp groups were markedly higher than the control group and before experiment(P<0.05),BMD of spine(L₂～L₄) and left trochanter in three experimental groups were markedly higher than the control group(P<0.01) and before experiment(P<0.0).Conclusion Both estrogen replacement therapy and sport walking with weight effectively improve serum lipid,prevent and reverse osteoporosis induced by menopause in women.
