Changes in Blood Pressure After Single Bout of Aerobic Exercise in Young Healthy People- Influence of Body Composition.

Amount of change in blood pressure after exercise is related to risk of hypertension and cardiovascular diseases. The aim of this study was to determine whether there is a difference in the amount of change of blood pressure after exercise among people with different morphological characteristics, especially with differences in percent of body fat. 30 healthy subjects (15 males and 15 females) aged 25-30 years were included in the study. They were measured for weight and height, and their body composition was assesed by bioelectrical impendance device GAYA 357. Blood pressure was measured at rest and immediately after performing Cooper´s test. After classification of subjects according to BMI (body mass index) and according to percent of body fat (PBF) differences in the size of change in blood pressure among categories were compared. Results indicate that there is no difference between sexes in amount of change for DBP, but there is difference in change of SBP; in males this change was significantly higher than in females. We also found difference in SBP results at rest between different categories of BMI (p=0,023), that was not influenced by gender, while the difference between categories based on different PBF were under the influence of gender. Based on results conclusion can be made that percent of body fat is a factor that influence amount of change in blood pressure with exercise, and is potentially important, and could be predictive factor, like BMI or together with it, in determining the risk of hypertension in young healthy people.
