Firstly, due to dynamic exercise, we hypothesised that dynamic exercise will increase heart rate, systolic pressure, pulse pressure, but decreases diastolic pressure due to vasodilation of the aorta, and the mean arterial will remain the same.
The figures illustrate the effect of exercise for instance figure 1, 3 ,4, and 5 shows an increase in systolic pressure, pulse pressure, heart rate and mean arterial pressure compared to at rest, whereas figure 2 shows a decrease in diastolic pressure due to peripheral vasodilation, which facilitates blood flow to the working muscles. Secondly, during dynamic exercise, the sympathetic branch of the autonomic nervous system start activation. The sympathetic nervous system is responsible for the "fight-or-flight" …show more content…
The p-value for systolic pressure, diastolic pressure, heart rate and pulse pressure were p0.05.
Systolic, diastolic, pulse pressure and heart rate has increased significantly p0.05 therefore we are going to accept the null hypothesis as our hypothesis was significant and because the P value was greater than the significance level.
However, errors and limitation can occur in this type of hypothesis. The sources of errors that can occur in such hypothesis can be human error, or instrument used was not calibrated this might affect the measured blood pressure, hence skewing the result.
The limitations of such hypothesis can be that the person may not exercise as the other person creating problems for the result; therefore, there will be a difference in the diastolic pressure.
Lastly, due to biological variation in individuals hence there will be no similarity in blood pressure and diastolic pressure.
The errors can be improve by ensuring that all equipment used for the experiment are well calibrated and tested before using. As such, error can be prevented and improvement of results may
