Purpose of the study was to find out the physiological differences between the athletes of selected events in track and field. A total of 30 subjects (10 from each event) were selected by purposive sampling from LNUPE, Gwalior. The variables selected for this study were Vital Capacity, Resting Pulse Rate and Blood Pressure. The resting pulse rate of each of the subject was recorded in the morning on their bed, just after the sound sleep. It was recorded through the radial artery. The blood pressure was measured (diastolic and systolic) with sphygmomanometer (dial-type) and the stethoscope in millimeters of mercury (mmHg). Maximal volume forcefully expired after maximal inspiration (Vital Capacity) was measured with the help of dry Spiro-meter in liters. The One Way Analysis of Variance was employed for the analysis of data. The level of significance was set at 0.05. The result of the study was found that there was a significant difference in the vital capacity and resting pulse rate of sprinters, jumpers and long distance runners. But, no significant differences were found in case of Blood Pressure (i.e. systolic and diastolic blood pressure).
