Question

1. Sit down with a family member and measure the pulse rate in their radial artery. You can do this by placing your index and middle finger on the underside of their wrist, below the base of the thumb. Take three separate readings (30 seconds each). Calculate the beats per minute by multiplying each reading by two and find the average. Record this in table one. This value will also be your trial 1 result in table two.
2. Have your relative repeat step one on you.
3. You and your family member will run on the spot for three minutes. Use a timer to guide you. Immediately after the three minutes, check each other’s pulse by following the instructions at step one. Record these results in trial 2.
4. Rest for five minutes and measure each other’s pulse rate again. Record this as trial 3.
5. Repeat steps three and four two more times. This will give you the results for trials 4-7.

Pulse rate 1	Pulse Rate 2	Pulse Rate 3	Average

1. Trial	Activity	Your pulse rate	Family member pulse rate
   1	Average resting pulse rate
   2	Immediately after exercising
   3	After resting for five minutes
   4	Immediately after exercising
   5	After resting for five minutes
   6	Immediately after exercising
   7	After resting for five minutes

1. Compare your pulse rate to that of your family member. Give a possible reason (s) for any difference observed.

2. The normal pulse rate for adults is 60-90 beats per minute. Compare this to your pulse rate. Give a possible reason (s) for any difference observed.
3. How does your pulse rate change after running on the spot? Why do you think this happens?

Answer 1

ANSWER :-

PULSE RATE 1	PULSE RATE 2	PULSE RATE 3	AVERAGE
TRIAL	ACTIVITY	YOUR PULSE RATE	FAMILY MEMBERS PULSE RATE
1	Average resting pulse rate	82	64
2	Immediately after exercising	114	92
3	After resting for five minutes	80	68
4	Immediately after exercising	122	98
5	After resting for five minutes	84	68
6	Immediately after exercising	120	102
7	After resting for five minutes	82	74

1. First of all, being a younger individual, taking my age into consideration, the maximum heart rate that I can achieve is (220-24 = 196 bpm) and as the relative is of mid-age, there will be reduction in the heart rate when running and also there will be time for recovery after exercise is being done in the form of running on spot.
2. This difference in the heart rate can be spotted from the table represented above. Basically, during an exercise, the muscles and the cells need more input of oxygen which can be transported by blood and hence the heart starts to pump a large volume of blood to the appropriate regions which in turn is associated with an overall increase in the pulse rate.
