Effect of Regular Physical Activity on Physical Efficiency of female subjects (Indian).

Present investigation evaluated the effects of regular physical activity on Body Fitness and Cardio-respiratory responses of middle aged Women (n=100) working in rural brick field located at remote village in paschim Medinipur district and non working women (n=100) living in Medinipur (West) district town .All subjects were belongs to age group in between 35 years to 45 years. Anthropometric data of Vertical Height and Body mass of women living in District Town and rural working women were measured by Anthropometer Rod, Weighing machine and compared. Body fat percent was estimated of the subjects of both groups by Siri Equation putting the value of arm skinfold thickness and iliac skinfold thickness using Harpenden Skin Fold Calipers. VO2 max was determined by treadmill exercise with direct measurement of oxygen consumption. Pulmonary minute ventilation (VE)of the subjects of both group were measured by Electronic Spirometer. Blood Pressure was measured by Sphygmomanometer and Radial Pulse rate (beats /min) was measured. Blood Haemoglobin Concentration was measured by spectrophotometrical technique and compared. Erythrocyte count of the subjects of both rural and urban area was taken by Automatic Coulter Counter. Working(Heavy)women living in rural area had significantly higher body mass, physical efficiency and aerobic capacity than women living in urban area Nonworking women living in town area showed a significantly (p<0.05) lower cardio-respiratory responses to exercise than working women living in rural area. Insignificant (p>0.05) difference of R.B.C count, blood haemoglobin concentration (gm %) and body mass of rural subjects in respect of non working women of urban area was observed. Regular systematic exercise has some induction role in oxygen transport to tissues, oxygen uptake by tissues, muscular strength as well as physical efficiency in either sex of human beings.
