Heart rate and Exercise

Question 1

Why can trained individuals train at a high intensity for longer?

Answer 1

Because they have a greater range in heart rate

Question 2

Give an example of a heart rate range

Answer 2

Mo Farah
- Max HR = 220-36 = 184bpm
- Resting HR = 33bpm
- Range = 184-33 = 151bpm

Question 3

Describe the sub-maximal HR graph

Answer 3

Begins with an anticipatory rise, then a sharp rise, then begins to level off into a steady state, then a rapid decline occurs which is followed by a recovery.

Question 4

Describe the maximal HR graph

Answer 4

Begins with an anticipatory rise, then a sharp rise which continues to rise until exercise stops, a rapid decline then occurs which is followed by recovery.

Question 5

What is anticipatory rise? (a)

Answer 5

Heart rate increases due to release of adrenaline (arousal levels rise)

Question 6

Why does the sharp rise occur? (b)

Answer 6

Due to the body working anaerobically

Question 7

Why does HR continue to rise? (c)

Answer 7

As the body continues to work anaerobically, therefore doesn’t reach a steady state.

Question 8

Why does the heart rate level off into a steady state? (d)

Answer 8

As oxygen supply meets oxygen demand, they’re working aerobically

Question 9

What causes the rapid decline? (e)

Answer 9

Exercise stopping

Question 10

Why does heart rate slowly decrease in recovery? (f)

Answer 10

In order to remove waste products such as lactic acid and CO2. (EPOC)
