Investigating Pulse Rate

You will have lower pulse rate when you are jogging but higher pulse rate when you are running.

• True

• False

• Both jogging and running will give same pulse rate

Who has the highest pulse rate?

• Father

• Son

• Grandfather

• All have the same pulse rate

What is the effect of exercise on pulse rate?

• Exercise causes pulse rate to remain constant.

• Exercise has no effect on pulse rate.

• Exercise increases pulse rate.

• Exercise decreases pulse rate.

Answer explanation

Exercise increases pulse rate.

Define homeostasis in the context of pulse rate regulation.

• Homeostasis refers to the body's ability to regulate blood sugar levels

• Homeostasis in pulse rate regulation involves maintaining body temperature

• Homeostasis is the process of controlling muscle movement

• Homeostasis in pulse rate regulation refers to the body's ability to maintain a stable heart rate within a normal range.

Answer explanation

Homeostasis in pulse rate regulation refers to the body's ability to maintain a stable heart rate within a normal range.

How does the body maintain a stable pulse rate during rest?

• Sympathetic division of the autonomic nervous system speeds up the heart rate by releasing adrenaline.

• The body temperature decreases, leading to a slower pulse rate.

• Increased intake of caffeine causes the heart rate to stabilize.

• Parasympathetic division of the autonomic nervous system slows down the heart rate by releasing acetylcholine.

Answer explanation

The parasympathetic division of the autonomic nervous system slows down the heart rate by releasing acetylcholine, helping maintain a stable pulse rate during rest.

What are the factors that can influence an individual's pulse rate?

• Physical activity, stress levels, caffeine intake, medication, body temperature, overall health condition

• Recent meals, shoe size, favorite color

• Weather conditions, time of day, music preference

Answer explanation

The factors that can influence an individual's pulse rate include physical activity, stress levels, caffeine intake, medication, body temperature, and overall health condition.

Why is it important to monitor changes in pulse rate during physical activity?

• To count the number of steps taken

• To assess exercise intensity, prevent overexertion, and detect health issues.

• To measure the temperature of the environment

• To track the amount of water consumed

Answer explanation

Monitoring changes in pulse rate during physical activity is important to assess exercise intensity, prevent overexertion, and detect health issues.

How can one measure their pulse rate accurately at home?

• Use a stethoscope to listen to the pulse

• Measure pulse rate after exercising vigorously

• Count the beats for 1 minute instead of 30 seconds

• Rest for a few minutes, place two fingers on the wrist, neck, or chest, count the beats for 30 seconds, and multiply by 2.

Answer explanation

To measure pulse rate accurately at home, rest for a few minutes, place two fingers on the wrist, neck, or chest, count the beats for 30 seconds, and multiply by 2.

Why might pulse rate vary significantly between individuals?

• Due to differences in body size and composition only.

• Because of varying levels of physical fitness and genetic factors.

• It is solely based on the individual's age.

• Pulse rate variation is a myth; it does not vary significantly between individuals.

How does body position (sitting, standing, lying down) affect pulse rate?

• Body position has no effect on pulse rate.

• Pulse rate is higher when lying down compared to standing.

• Pulse rate increases when moving from a lying or sitting position to a standing position.

• Pulse rate decreases when moving from a standing to a lying position.
