Variation of Blood Pressure, Heart Rate and Oxygen Consumption and Their Relationship with Body Lipid Profile in Active and Inactive Students

This study aimed at investigating the variations of blood pressure, heart rate and oxygen consumption and their relationship with body lipid profile in active and inactive students. 10 active students (mean age 21 yr, weight 68.1 kg and height 174.1 cm) and 10 inactive students (mean age 21.5 yr, weight 73.07 kg and height 177 cm) from Shahid Rajaee Teacher Training University who volunteered to participate in the study were randomly selected. The participants performed Canningham Faulkner submaximal treadmill test until exhaustion (slope: 20%, speed: 12.9 km/hr). Firstly, sitting systolic and diastolic blood pressures (SBP, DBP), sitting heart rate (HR), double product (DP), blood lipid, visceral fat, body fat ratio and body mass index were measured before the test. Then sitting BP and HR and DP were measured immediately after the test and after 3 minutes. The analysis of variance and covariance with repeated measures were used for data analysis. The results showed that recovery of HR (P=0.006, F=6.012), SBP (P=0.02, F=4.353) and DP (P=0.004, F=6.38) occurred more in active students. Modification of results with overweight and blood lipids showed the relationship between some of these indices and poor recovery in inactive students. So it can be stated that fitness and physical activity had positive effects on better recovery of hemodynamic indices after exercise even though no differences were observed in resting and exercise values. Overweight and dyslipidemia can partially explain some of these differences between active and inactive.
