Aim: To evaluate aerobic capacity in trained and untrained subjects by recording systolic blood pressure and Vo2 max after exercise. Methods and Materials: In the present study 40 healthy male subjects who are studying physiotherapy course between the age group 22-24 years were selected. One group is not having any specific physical exercise that is control group and the second group which includes subjects who regularly do the cycling for 30 minutes all the days in a week since 6 months that is examination group. All the readings were taken 8:15 to 8:30 am from all the subjects before the breakfast. We took 3 readings for each parameter from each subject and took the average of the 3 readings. The subjects were asked to peddle the bicycle ergo metre first with a resistance of 2 kg for 5 minutes next with a resistance of 4 kg for 3 minutes there after resistance is increased by 0.5 kg for every 3 minutes until the subject is exhausted. Immediately after the exercise heart rate and systolic blood pressure were recorded with E.C.G and sphygmomanometer respectively. Statistical analysis: The data was analysed by using the Student’s t-test. P value less than 0.05 is considered as significant. Results & Conclusion: Vo2 max and the systolic blood pressure are higher in trained subjects than in untrained subjects after the exercise. P-value of systolic blood pressure is 0.001 and Vo2 max is 0.005 which are highly significant.
