Question

1. Describe what happened to heart rate and systolic blood pressure at each posture. Is this what you expected? Why or why not? Explain why you should see change in these variables with changes in posture.

Answer 1

Heart rate for adults remains for 60 to 100 beats per minute in which a lower rate of heart implies the more efficient function of the heart and better cardiovascular fitness. Heart rate takes place many times in which one can observe the different types of beats per minute when they are resting.
Systolic blood pressure refers to the amount of pressure in the artery which is observed during the contraction of the heart muscle. This is also referred to as blood pressure in which the heart muscle is between the beats. Systolic blood pressure can be caused due to some underlying conditions like the stiffness of artery and hyperthyroidism or Diabetes.
There are different postural effects on heart rate and but systolic pressure there are different types of body positions in which one can observe different types of blood pressure.
The sitting‐lying- in this posture one can observe the increased blood pressure and Pulse rate because the trunk is moved towards the vertical position.
The sitting‐standing- in this posture one can observe the hydrostatic influence that acts on the change of the thigh in two different postures.
The squatting posture- the level of tissues and vessels which are involved in this position. One can observe the lower down of heart rate and systolic blood pressure in this posture.
Yes, these are the posture which we expect because of the body at the different cardiac output. One should see the changes in this variable which change with posture because of different other organs that are related to this. The static concentration of muscles is also responsible to change the systolic and diastolic blood pressure.
