|---|---|---|---|---|---|
| Anticipatory rise in heart rate prior to exercise | The release of adrenalin prepares your body for the increased demands exercise will put on the body
🗑
|
||||
| Increased heart rate | due to the rise in carbon dioxide picked up by the chemoreceptors.
🗑
|
||||
| Increased cardiac output | exercise increases the demand for oxygen, so cardiac output also increases
🗑
|
||||
| Cardiac output | stroke volume X heart rate (amount of blood pumped from the heart in 1 minute)
🗑
|
||||
| Stroke volume | the amount of blood ejected by the heart per beat
🗑
|
||||
| Heart rate | the number of times the heart beats per minute
🗑
|
||||
| Increased blood pressure | exercise means more blood is pumped through the blood vessels
🗑
|
||||
| Blood pressure | the pressure of the blood against the walls of your arteries
🗑
|
||||
| Systolic (top number) | the pressure on your artery wall when the heart contracts
🗑
|
||||
| Diastolic (bottom number) | the pressure on your artery when the heart relaxes
🗑
|
||||
| What happens to blood flow during exercise | It is redirected from the digestive system (vasoconstriction) to the working muscles (vasodilation)
🗑
|
||||
| Cardiac Hypertrophy | where the walls of the heart gets thicker, this increases the strength of its contractions
🗑
|
||||
| Cardiac Hypertrophy means the heart can... | pump more blood per beat so can transport more oxygen to the working muscles
🗑
|
||||
| Why does exercise lead to a decrease in resting heart rate? | Because the heart is bigger and can pump more blood per beat, the heart does not have to work as hard
🗑
|
||||
| Exercise leads to a reduction in resting blood pressure, what does this reduce the risk of? | heart disease & stroke
🗑
|
||||
| Exercise increases capillarisation, what does this lead to? | more oxygen & nutrients can be diffused into the blood from the alveoli and into the muscles
🗑
|
||||
| Sudden Arrhythmic Death Syndrome (SADS) | a heart condition that can cause sudden death.
🗑
|
||||
| What is SADS usually caused by? | an irregular heart beat (cardiac arrythmia)
🗑
|
||||
| Hypertension | high blood pressure (risk for heart disease & stroke)
🗑
|
||||
| Hypotension | low blood pressure
🗑
|
||||
| Hyperthermia | increase in core body temperature (can lead to heat stroke)
🗑
|
||||
| Hypothermia | drop in core body temperature below 35C
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
