SOC:9 The Long Term Effects Of Exercise

Question 1

Adaptation

Answer 1

Your body’s response to training and how your body changes to cope with new activity

Question 2

Aerobic

Answer 2

Working at a moderate intensity level with oxygen

Question 3

Anaerobic

Answer 3

Working at a high intensity level without oxygen

Question 4

Alveoli

Answer 4

Tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream

Question 5

Diaphragm

Answer 5

The primary muscle used in the process of inspiration or inhalation

Question 6

Cardiac output

Answer 6

The amount of blood ejected from your heart in one minute (CO) = (SV) x (HR)

Question 7

Resting stroke volume

Answer 7

The amount of blood pumped per beat

Question 8

Recovery rate

Answer 8

The speed at which your heart returns To RHR after you exercise

Question 9

Effects on the musculo- skeletal system

Answer 9

-Increased strength of ligaments and tendons
-Increased bone density
-Muscle hypertrophy
-Adaptation

Question 10

Effects on the respiratory system - your lungs

Answer 10

Increased lung capacity/ volume and vital capacity
Your lungs will become more efficient, and they will be better at delivering oxygen to your working muscles, so your body will cope better during exercise.

Increased number of alveoli
More alveoli will become available for gaseous, exchange after regular exercise, so more
oxygen can be absorbed by the capillaries and more carbon dioxide taken from them.

Increased strength of the diaphragm and external intercostal muscles.
Exercise increases the strength of the diaphragm and the external intercostal muscles – the muscles that work to increase airflow during physical activity

Question 11

Effects on the cardio system - your blood

Answer 11

Capillaries: Improved fitness increases the number of capillaries in your heart muscle and helps your blood vessels more elastic, flexible and efficient.

Increased number of red blood cells: These cells carry oxygen to the muscles, so having higher red blood cell count can improve their performance.

Drop in resting blood pressure: regular exercise reduces blood pressure due to the

Question 12

Effects on the cardio system - your heart

Answer 12

Decreased resting heart rate: Your heart gets bigger/ stronger with training, so it can supply the same amount of blood with fewer beats.

Faster recovery rate: Heart recovery rate is the speed at which your heart returns to RHR after you exercise. The faster your recovery rate, the fitter you are.

Increased resting stroke volume: Stroke volume is the amount of blood pumped by your heart per beat. When you exercise regularly, your stroke volume increase, both at rest and at work.
Maximum cardiac output: The amount of blood ejected from your heart in one minute. Cardiac output (CO) = stroke volume (SV) X heart rate (HR).

Size and strength of the heart: Training increases the heart muscles in size, thickness and strength
