The Effects Of Exercises On Bone Healh Of Middle And Old-aged Women

Among all kinds of precaution and treatment steps for osteoporosis, exercise has been taken seriously by the academic circles. So far ,the studies in osteoporosis focus mainly on bone mass , the bone mass measure is certainly important , but it can not comprehensively reflect the seriousness extent of bone laxity and the decrease of bone mechanics,and with age increasing,the muscle function of the middle and old-aged also decreases. Based on the human objects of 195 middle and old-aged women that take physical examination in Beijing FuChan hospital , by using the DPX-IQ DEXA, MES-O1 S20 Mobility Evaluation System,mathematical analysis and other scientific research methods,this dissertation attempts to make a study about the effects of exercise on the old and middle-aged women's bone health,in order to provide suggestions for preventing and treating the OP more widely. The experiments indicates:(l)Exercise plays an important role in the health of human bone, it can prevent the incidence of bone fracture by retarding the bone loss and the decrease of bone mechanical strength , maintaining the muscle strength and the elasticity and steadiness ofjoints.(2)The non-systematic exercise that old man usually take , also plays a significantly optive role in their bone strength and the bone density on different sites.(3)The bone strength was strongly optively correlated with bone mineral density and limber maximum muscle strength , was strongly negatively correlated with weight, body fat and BMI.Long -term exercise can play an important role in the prevention of osteoporosis by maintaining weight, body figure, strengthening muscle strength .(4)The prescription of preventing osteoporosis is medium or high density exercise no less than half an hour every time and no less than three times per week .
