Study of Changes in Respiratory Rate Following an Exercise Bout
Pintu SilAssistant Professor, State Institute of Physical Education for Women, Hastings House, Kolkata, India.
During all types of exercise respiratory rate is increased as a result of increased demand of Oxygen. The purpose of the study was to find out the maximum changes in respiratory rate following an exercise bout and to study the recovery period of respiratory rate after completing an exercise bout in three categories of women - obese, normal and lean. A total of 13 young adult female within the age of 21-30 years were volunteered as subject for this study. Each subject’s body fat were measured and classified under three groups’ namely overweight or obese group (G1), Normal group (G2) and Lean or underweight group (G3). Respiratory rate was considered as criterion of the present study. Respiratory rate was measured manually by observation of breath in and breathe out per minute. Standard stop watch was used for time specification. Step up and down for five minutes was used as exercise protocol. All data for the present study was collected at average 25.210C temperature and 63.33% humidity. Multiple group design with three independent groups was considered for the present study. All calculations were done by the standard statistical procedure. Findings have revealed that respiratory rate significantly increased (F=9.4) for all groups of subjects immediately after exercise (p<0.05). The raise of respiratory rate immediate after exercise was found highest for G1 group and lowest for G3 group. The recovery period was found longest for G1 group (15.33 min) and shortest for G3 group (7.5 min). Result clearly indicated that respiratory rate increased significantly immediately after exercise in all categories of women but recovery period of respiratory rate was not significantly different for women having different body fat.
