The Research On Feasible Exercise Intensity Of Women Aged From 56 To 60y

The research studied the different changes observed on 33 women aged from 56 to 60 years old after an 8-week exercise at different intensities. All subjects were divided into 3 groups and given walking exercise (3 times per week, 30 min on THR time) at different intensities which are according to the percentage of Function Capacity (FC): 30-45%FC, 46-60%FC and 61-75%FC. We compared the data on configuration and body composition, cardio-respiratory capacity and blood fat took before and after 8-week's walking.The results are showed as followed, lower intensity (30-45%FC) seems to threw better effect on body composition, reduce the content and percentage of body fat and blood fat, decrease the systolic pressure and improve vital capacity. Middle intensity (46-60%FC) can improve the cardiac fitness, e.g. increase EDD, EDV, EF, SV, reduce FIR and enhance the contraction ability of cardiac muscles, also meliorate vital capacity and systolic pressure. Higher intensity (61-75%FC) can visibly enhance the cardiac fitness and vital capacity, expedite reaction time and make better of the metabolic ability of body fat, but it has no effect on FC, blood pressure and body composition. Different intensity seems to have no apparent effect on balancing and coordination ability.The research observed different effects on different system at different exercise intensity. Different intensities are suitble for different aims of physical exercises. The conclusions can be drew as followed,1 xercise for good shape and reducing body fat, lower intensity (30-45%FC) should be taken,2 Exercise for decreasing blood pressure and blood fat, lower and middle intensity should be selected,3 xercise for enhancing the cardiac capacity, middle intensity (46-60%FC) should bechoosed,4 xercise for increasing vital capacity, all intensity (30-75%) can be selected,hose who have been basically trained and no disease on the heart and vessel, 61-75%FCshould be suitable for their further training. Special related exercises are needed to improve balancing, flexibility and coordination.
