Comparative Study of Change in Physical Activity on Cardio-respiratory Efficiency and Exercise Performance in Sedentary Females
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2014, Vol 2, Issue 1
Abstract
Few data are available regarding the outcome of women in cardiac rehabilitation. To determine whether women are differing in physical profile and outcome, 45 sedentary females were prospectively studied for post exercise cardio-respiratory changes and exercise efficiency. Females were divided into five groups, 9 in each. Each group performed different exercise (whole body, walking, upper limb, lower limb and combined exercise) for 12 weeks under the supervision of physical trainer. Interventions included respiratory rate, resting pulse rate, blood pressure, forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR), 6 minute maximum walking distance (6 MWD), 12 minute maximum walking distance (12 MWD), 6 minute maximum bicycle ergo meter (6 MBE) test and 6 minute maximum arm ergo meter (6MAE) test. Parameters were studied twice before and after exercise training. Students paired t test was applied for pre and post data analysis. Cardio- respiratory efficiency found to be significantly higher in response to whole body, combined and walking exercises. The other modes like only upper limb or only lower limb exercise are not as beneficial. Exercise performance showed non-significant results except 6MBE distance. In conclusion cardio respiratory efficiency was improved by regular exercise training and whole body, walking and combined exercises are better than upper and lower limb exercises.
