Lab Q/A

Laboratory Activity: Blood Pressure and Exercise

Subject: Colleen Richards Date: October 21, 2021

Tester: Nisha Jasani

Sex: M/F (highlight one) Age: 21 yrs

Directions:

1. Lie supine for 5 minutes

2. Take Supine Blood Pressure

3. Immediately following supine BP, take Initial standing BP.

4. Following Initial standing BP, wait 2 minutes to take Standing BP.

5. Sit down for 2 minutes and then take Sitting BP.

6. Repeat steps for Trial 2.

Blood Pressure (mmHg)
	Supine Position	Initial Standing	Standing Position	Sitting Position
Trial	Systolic	Diastolic	Systolic	Diastolic	Systolic	Diastolic	Systolic	Diastolic
1	120	78	120	82	120	85	125	80
2	130	80	125	85	120	82	120	78
Average	125	79	123	84	120	84	123	79

*Count HR for 60 seconds*

Resting Heart rate (Sitting Position): 69 bpm

Resting Heart rate (Supine Position): 78 bpm

Blood Pressure Classification (Table 4.2)
Sitting Position	High
Supine Position	High
Initial Standing	High
Standing Position	High

Blood Pressure During Cycling
	Time (minutes)	Intensity (Watts)	Systolic (mmHg)	Diastolic (mmHg)
Stage 1	2	50	130	85
Stage 2	4	70	145	75
Stage 3	6	100	148	80
Stage 4	8	120	165	75
Recovery	5	0	128	80

Blood Pressure: Upper-Body Isometric (Handgrip)
	MVC	30% MVC	Systolic (mmHg)	Diastolic (mmHg)
Trial 1	26	8	130	88

Blood Pressure: Lower-Body Isometric (Wall Sit)
	Time (minutes)	Systolic (mmHg)	Diastolic (mmHg)
Trial 1	3	145	82

Questions: Please write your answers underneath the questions in sentence/paragraph form (no bullet points). These answers should be in YOUR OWN words. Do not copy the answers from other laboratory students.

1. How do SBP and DBP response to cycling exercise of increasing intensity? What should the response to SBP and DBP be when performing exercise?

2. How does the blood pressure response during isometric handgrip compare with the response during isometric wall sit. Explain differences.

3. Explain the changes you observed in blood pressure with the different body positions. Explain what accounts for differences in blood pressure. Which position should contain the highest blood pressure reading? Which one should contain the lowest blood pressure reading? Explain why.

4. What is happening physiologically when a person stands up quickly and gets light-headed?
