Effect of accumulated aerobic work with a progressive intensity on the blood pressure variables and Heart Rate

Abstract

The importance of current study lies in being acquainted with the temporary effect of an aerobic work upon the blood pressure variables in healthy subjects. The study aimed at being acquainted with the values of blood pressure variables at each of two minutes as a temporary response throughout a progressive intensity aerobic work lasting 14 minutes in addition to be acquainted with the limits of significant change in blood pressure values throughout this effort. The sample included 10 students from the college of physical education at university of Mosul. The sample conducted a standardized test of aerobic effort for 14 minutes. The variables of heart rate (HR), diastolic blood pressure (DBP), systolic blood pressure (SBP), mean arterial pressure (MAP), and pulse pressure (PP) were measured at each of two minutes throughout the effort period in addition to measure them at rest. The values of variables at rest had compared with the effort states in addition to compare the latter values at each of two minutes with the next one throughout the effort period. The means, standard deviations, and ANOVA by repeated measurements were used to process data statistically. There were signifigant differences between the rest and some stages of effor for the variables of SBP, HR, MAP and PP. Having the result presented and discussed, the study concluded the following:  The progressive intensity aerobic effort makes a significant change in variables of blood pressure in comparison with the rest (excluding the variable of DBP), in addition, when transferring from one stage of the effort to another progressive one. However, the latter change was until specific limit.  The change occurring in variables of SBP, HR, MAP, and PP when transferring form the rest to effort does not contentious throughout all stages of the progressive intensities effort, but values of those variables stabilize approximately at the first third of effort where as the HR does not stabilize until the final stage of effort. Finally, the study recommended to conduct future studies dealing with blood pressure variables at other various intensities and durations
